Objectives To elucidate the phenotypes and pathophysiology of speech and voice disorders in Parkinson's disease (PD) with subthalamic nucleus deep brain stimulation (STN-DBS). Methods We conducted a cross-sectional study on 76 PD patients treated with bilateral STN-DBS (PD-DBS) and 33 medically treated PD patients (PD-Med). Speech and voice functions, electrode positions, motor function and cognitive function were comprehensively assessed. Moreover, speech and voice functions were compared between the on-stimulation and off-stimulation conditions in 42 PD-DBS patients. Results Speech and voice disorders in PD-DBS patients were significantly worse than those in PD-Med patients. Factor analysis and subsequent cluster analysis classified PD-DBS patients into five clusters: relatively good speech and voice function type, 25%; stuttering type, 24%; breathy voice type, 16%; strained voice type, 18%; and spastic dysarthria type, 17%. STN-DBS ameliorated voice tremor or low volume; however, it deteriorated the overall speech intelligibility in most patients. Breathy voice did not show significant changes and stuttering exhibited slight improvement after stopping stimulation. In contrast, patients with strained voice type or spastic dysarthria type showed a greater improvement after stopping stimulation. Spastic dysarthria type patients showed speech disorders similar to spastic dysarthria, which is associated with bilateral upper motor neuron involvement. Strained voice type and spastic dysarthria type appeared to be related to current diffusion to the corticobulbar fibres. Conclusions Stuttering and breathy voice can be aggravated by STN-DBS, but are mainly due to aging or PD itself. Strained voice and spastic dysarthria are considered corticobulbar side effects.

Introduction: Connector hubs are specialized brain regions that connect multiple brain networks and therefore have the potential to affect the functions of multiple systems. This study aims to examine the involvement of connector hub regions in essential tremor. Methods: We examined whole-brain functional connectivity alterations across multiple brain networks in 27 patients with essential tremor and 27 age- and sex-matched healthy controls to identify affected hub regions using a network metric called functional connectivity overlap ratio estimated from resting-state functional MRI. We also evaluated the relationships of affected hubs with cognitive and tremor scores in all patients and with motor function improvement scores in 15 patients who underwent postoperative follow-up evaluations after focused ultrasound thalamotomy. Results: We have identified affected connector hubs in the cerebellum and thalamus. Specifically, the dentate nucleus in the cerebellum and the dorsomedial thalamus exhibited more extensive connections with the sensorimotor network in patients. Moreover, the connections of the thalamic pulvinar with the visual network were also significantly widespread in the patient group. The connections of these connector hub regions with cognitive networks were negatively associated (FDR q < 0.05) with cognitive, tremor, and motor function improvement scores. Conclusion: In patients with essential tremor, connector hub regions within the cerebellum and thalamus exhibited widespread functional connections with sensorimotor and visual networks, leading to alternative pathways outside the classical tremor axis. Their connections with cognitive networks also affect patients’ cognitive function.

Sporadic inclusion body myositis (s-IBM) is an acquired degenerative inflammatory myopathy that leads to slowly progressive muscle weakness and atrophy of the limbs, face, and pharynx. Owing to the slow progression of the disease, the indications for surgical intervention remain unclear. Herein, we retrospectively reviewed the records of four patients with s-IBM who had undergone cricopharyngeal myotomy for severe dysphagia at our institution between 2016 and 2021. Among these, one patient underwent transcervical cricopharyngeal myotomy and laryngeal suspension, as videofluoroscopic examination of swallowing revealed poor laryngeal elevation. The remaining three patients underwent endoscopic cricopharyngeal myotomy using a curved rigid laryngoscope. Preoperatively, the mean Hyodo score was 8 points (range: 6-10) using a flexible endoscope. The mean surgical duration was 104 min, and no severe complications were observed. Postoperatively, all patients achieved improvement in swallowing function and food intake. Moreover, swallowing function was maintained in all four patients even 6-12 months postoperatively. Cricopharyngeal myotomy may be a safe surgical procedure with the potential to improve swallowing function, and a Hyodo score of 6 may be considered a surgical indication for cricopharyngeal myotomy in patients with s-IBM.

Introduction: Patients with Parkinson's disease (PD) encounter a variety of speech-related problems, including dysarthria and language disorders. To elucidate the pathophysiological mechanisms for linguistic alteration in PD, we compared the utterance of patients and that of healthy controls (HC) using automated morphological analysis tools. Methods: We enrolled 53 PD patients with normal cognitive function and 53 HC, and assessed their spontaneous speech using natural language processing. Machine learning algorithms were used to identify the characteristics of spontaneous conversation in each group. Thirty-seven features focused on part-of-speech and syntactic complexity were used in this analysis. A support-vector machine (SVM) model was trained with ten-fold cross-validation. Results: PD patients were found to speak less morphemes on one sentence than the HC group. Compared to HC, the speech of PD patients had a higher rate of verbs, case particles (dispersion), and verb utterances, and a lower rate of common noun utterances, proper noun utterances, and filler utterances. Using these conversational changes, the respective discrimination rates for PD or HC were more than 80%. Conclusions: Our results demonstrate the potential of natural language processing for linguistic analysis and diagnosis of PD.

Individuals with prodromal symptoms of Lewy body disease (LBD), such as rapid eye movement sleep behavior disorder (RBD), often showed imaging defects similar to patients with Parkinson’s disease and dementia with Lewy bodies. We examined dopamine transporter (DaT) single-photon-emission computed tomography (SPECT) and metaiodobenzylguanidine (MIBG) scintigraphy in 69 high-risk subjects with ≥2 prodromal symptoms (dysautonomia, hyposmia, and probable RBD) and 32 low-risk subjects without prodromal symptoms, whom were identified through a questionnaire survey of health checkup examinees. The high-risk subjects had significantly worse scores on Stroop test, line orientation test, and the Odor Stick Identification Test for Japanese than the low-risk subjects. The prevalence of abnormalities on DaT-SPECT was higher in the high-risk group than in the low-risk group (24.6% vs. 6.3%, p = 0.030). A decreased uptake on DaT-SPECT was associated with motor impairment, and MIBG scintigraphy defects were associated with hyposmia. The simultaneous evaluation of DaT-SPECT and MIBG scintigraphy may capture a wide range of individuals with prodromal LBD.

This study evaluated the safety of laryngeal closure and post-surgical changes in swallowing function of patients with amyotrophic lateral sclerosis (ALS) and proposed an appropriate surgical strategy for patients with ALS. Clinical and surgical data of 26 consecutive patients with ALS who underwent laryngeal closure at Nagoya University Hospital in Japan between 2003 and 2020 were retrospectively analyzed. Changes in swallowing functions were evaluated before and approximately 1 month post-surgery using Neuromuscular Disease Swallowing Status Scale (NdSSS), and Functional Oral Intake Scale (FOIS). The median operation time was 126 min (range, 51–163 min), and the median intraoperative blood loss was 20 mL (range, 0–88 mL). Among the 26 ALS patients who underwent laryngeal closure, grade 1 (mild) complications occurred in three patients (12%); however, no severe complications were observed. After surgery, 25 patients (96%) maintained the swallowing function and only one patient (4%) had deteriorating NdSSS and FOIS scores. No patients were referred to our hospital due to severe aspiration pneumonia after the surgery. Two patients did not require a feeding tube after the surgery and returned to oral intake. Laryngeal closure may be a safe surgical procedure for preventing chronic aspiration and may also maintain swallowing function of patients with ALS. Further multicenter prospective studies using the gold standard videofluoroscopic swallowing examination are required to support our findings.

OBJECTIVE The efficacy of magnetic resonance–guided focused ultrasound (MRgFUS) ablation for essential tremor (ET) is well known; however, no prognostic factors have been established. The authors aimed to retrospectively investigate MRgFUS ablation outcomes and associated factors and to define the cutoff values for each prognostic factor. METHODS Sixty-four Japanese patients who underwent unilateral ventral intermediate nucleus thalamotomy with MRgFUS for ET were included. Follow-up evaluations were performed at 1 week and 1, 3, 6, 12, and 24 months postoperatively. Tremor suppression was evaluated using the Clinical Rating Scale for Tremor (CRST), and adverse effects were recorded postoperatively. Outcome-associated factors were examined preoperatively, intraoperatively, and postoperatively using multivariate analyses. The cutoff values for the prognostic factors were calculated using receiver operating characteristics. RESULTS Percentage improvements in the CRST scores of the affected upper limb were 82.4%, 72.2%, 68.6%, and 65.9% at 1, 3, 6, and 12 months, respectively. Preoperatively, a high skull density ratio (SDR) (p ≤ 0.047), low CRST part B score (used to assess tremors during several tasks) (cutoff value 25, p ≤ 0.041), and nonoccurrence of resting tremors (p = 0.027) were significantly associated with improved tremor control. An intraoperatively high maximum mean temperature (cutoff value 52.5°C, p ≤ 0.047), postoperatively large lesion (cutoff value 3.9 mm in the anterior-posterior direction, p ≤ 0.002; cutoff value 5.0–5.55 mm in the superior-inferior direction, p ≤ 0.026), and small transducer focus correction (p ≤ 0.015) were also associated with improved tremor control. No valid cutoff value was found for SDR. Adverse effects (limb weakness, sensory disturbance, ataxia/walking disturbance, dysgeusia, dysarthria, and facial swelling) occurred transiently and were associated with high SDR, high temperature, high number of sonication sessions, large lesion, and occurrence of resting tremor. Patients who developed leg weakness experienced greater percentage improvement in tremors at 3 months postoperatively than those who did not. CONCLUSIONS MRgFUS ablation could be used to achieve good tremor control with acceptable adverse effects in Japanese patients with ET. The relatively low SDR in Asian ethnic groups as compared with that of Western populations makes treatment difficult; however, the cutoff values obtained in this study may be useful for achieving good treatment outcomes even in such patients.

Holmes tremor is a symptomatic tremor that develops secondary to central nervous system disorders. Stereotactic neuromodulation is considered when the tremors are intractable. Targeting the ventral intermediate nucleus (Vim) is common; however, the outcome is often unsatisfactory, and the posterior subthalamic area (PSA) is expected as alternative target. In this study, we report the case of a patient with intractable Holmes tremor who underwent dual-lead deep brain stimulation (DBS) to stimulate multiple locations in the PSA and thalamus. The patient was a 77-year-old female who complained of severe tremor in her left upper extremity that developed one year after her right thalamic infarction. Vim-thalamotomy using focused ultrasound therapy (FUS) was initially performed but failed to control tremor. Subsequently, we performed DBS using two leads to stimulate four different structures. Accordingly, one lead was implanted with the aim of targeting the ventral oralis nucleus (Vo)/zona incerta (Zi), and the other with the aim of targeting the Vim/prelemniscal radiation (Raprl). Electrode stimulation revealed that Raprl and Zi had obvious effects. Postoperatively, the patient achieved good tremor control without any side effects, which was maintained for two years. Considering that she demonstrated resting, postural, and intention/action tremor, and Vim-thalamotomy by FUS was insufficient for tremor control, complicated pathogenesis was presumed in her symptoms including both the cerebellothalamic and the pallidothalamic pathways. Using the dual-lead DBS technique, we have more choices to adjust the stimulation at multiple sites, where different functional networks are connected. Intractable tremors, such as Holmes tremor, may have complicated pathology, therefore, modulating multiple pathological networks is necessary. We suggest that the dual-lead DBS (Vo/Raprl and Vim/Zi) presented here is safe, technically feasible, and possibly effective for the control of Holmes tremor.

We present a 71-year-old woman with an eight-year history of Parkinson’s disease (PD). She began to experience wearing-off at the age of 66 and subsequently developed dyskinesia. She had worsened dyskinesias for three days, followed by a high fever, and she was subsequently hospitalized. On admission, severe dyskinesia, hyperpyrexia, and elevation of serum creatine kinase were observed. Severe dyskinesia without rigidity continued throughout the day and she was diagnosed with dyskinesia-hyperpyrexia syndrome (DHS). She was treated with standard medical care and anti-parkinsonian medications were reduced drastically. Dyskinesia started to wane three days after admission and almost disappeared on day twelve. Prior to admission, the patient reported she had been taking two to three times the dose prescribed of istradefylline, which was the suspected to be a trigger of DHS. Because DHS is a rare but potentially life-threatening complication, early recognition and diagnosis is vital. A proper treatment strategy for DHS may include standard medical care together with reduced anti-parkinsonian medications.

Holmes Tremor (HT) is an irregular, slow-frequency (<4.5 Hz) tremor characterized by a combination of resting, postural, and action tremors mostly of the upper extremities. Symptoms of HT typically emerge 4 weeks to 2 years after a brain injury caused by a spectrum of etiologies. HT pathophysiology is thought to result from aberrant collateral axonal sprouting and synaptic dysfunction following neuronal damage. To date, the dopaminergic nigrostriatal system, cerebello-thalamo-cortical pathway, and dentate-rubro-olivary pathway have all been implicated in the clinical manifestations of HT. The diversity of HT etiologies usually requires a personalized treatment plan. Current treatment options include carbidopa-levodopa, levetiracetam, and trihexyphenidyl, and surgical management such as deep brain stimulation in selected medication-refractory patients. In this review we discuss the pathophysiology, etiology, neuroimaging, and the latest clinical guidelines for care and management of HT.

Introduction: The impact of deep brain stimulation (DBS) on speech rhythm and its mechanism remains unclear. We investigated speech rhythm characteristics of patients with Parkinson's disease (PD) treated with subthalamic nucleus (STN) DBS to understand the underlying pathophysiology better. Methods: We enrolled a total of 105 participants and evaluated speech rhythm performances among patients with PD who had undergone STN-DBS (the PD-DBS group), patients with PD treated only with medication (the PD-Med group), patients with cerebellar ataxia (the CA group), and healthy controls (the HC group). Each participant was asked to repeat the syllable/pa/at a comfortable self-chosen steady pace. A widely-used software (the Motor Speech Profile) program performed an acoustic analysis. Results: Compared to the PD-Med and HC groups, speech rate instability (DDKjit) was significantly higher in the PD-DBS and CA groups (p < 0.01). However, after DBS was turned off, the DDKjit of the PD-DBS group improved to a level comparable to that of the PD-Med and HC groups. In contrast to the significantly higher variability of speech volume (DDKcvi) in the CA group, the PD-DBS group showed similar DDKcvi to the PD-Med and HC groups. Conclusions: STN-DBS affects the speech rate stability of patients with PD. Speech rhythm disorders caused by STN-DBS were phenotypically similar to that in CA in terms of interval variability but different regarding amplitude variability. Further studies are warranted to elucidate the underlying pathophysiology of speech rhythm disorders in PD patients treated with DBS.

Objective: The aim of this study is to evaluate the evolution of GPi DBS targeting. Methods: This retrospective, single-center study included patients implanted with GPi DBS leads for dystonia or PD during the years 2004 to 2018 at the University of Florida Fixel Institute for Neurological Diseases. Each patient underwent a high-resolution targeting study on the day prior to the surgery, which was fused with a high resolution CT scan that was acquired on the day of the procedure. Intraoperative target location was selected using a digitized 3D Schaltenbrand-Bailey atlas. All patients underwent a high-resolution head CT scan without contrast approximately one month after lead implantation and accurate measurement of neuroanatomical lead position was acquired after fusion of pre-operative and post-operative image studies. Results: We analyzed 253 PD patients with 352 leads and 80 dystonia patients with 141 leads. During 15 years of follow-up, lead locations in the PD group migrated more laterally (β = 0.09, p < 0.0001), posteriorly [slope (β) = 0.04, p < 0.05], and dorsally (β = 0.07, p < 0.001), whereas leads in the dystonia group did not significantly change position aside from a trend in the dorsal direction (β = 0.06, p = 0.053). Conclusion: The evolving target likely results from multiple factors including improvements in targeting techniques and clinical feedback intraoperatively and post-operatively. Our demonstrates the potential importance of a systematic post-operative DBS lead measurement protocol to ensure quality control and to inform and optimize DBS programming.

Background: Freezing of gait (FOG) is a common symptom in Parkinson’s disease (PD) and can be difficult to treat with dopaminergic medications or with deep brain stimulation (DBS). Novel stimulation paradigms have been proposed to address suboptimal responses to conventional DBS programming methods. Burst-cycling deep brain stimulation (BCDBS) delivers current in various frequencies of bursts (e.g., 4, 10, or 15 Hz), while maintaining an intra-burst frequency identical to conventional DBS. Objective: To evaluate the safety and tolerability of BCDBS in PD patients with FOG. Methods: Ten PD subjects with STN or GPi DBS and complaints of FOG were recruited for this single center, single blinded within-subject crossover study. For each subject, we compared 4, 10, and 15 Hz BCDBS to conventional DBS during the PD medication-OFF state. Results: There were no serious adverse events with BCDBS. It was feasible and straightforward to program BCDBS in the clinic setting. The benefit was comparable to conventional DBS in measures of FOG, functional mobility and in PD motor symptoms. BCDBS had lower battery consumption when compared to conventional DBS. Conclusions: BCDBS was feasible, safe and well tolerated and it has potential to be a viable future DBS programming strategy.

Background and purpose: Deep brain stimulation (DBS) is the most common surgical treatment for essential tremor (ET), yet there is variation in outcome and stimulation targets. This study seeks to consolidate proposed stimulation “sweet spots,” as well as assess the value of structural connectivity in predicting treatment outcomes. Materials and methods: Ninety-seven ET individuals with unilateral thalamic DBS were retrospectively included. Using normative brain connectomes, structural connectivity measures were correlated with the percentage improvement in contralateral tremor, based on the Fahn-Tolosa-Marin tremor rating scale (TRS), after parameter optimization (range 3.1–12.9 months) using a leave-one-out cross-validation in 83 individuals. The predictive feature map was used for cross-validation in a separate cohort of 14 ET individuals treated at another center. Lastly, estimated volumes of tissue activated (VTA) were used to assess a treatment “sweet spot,” which was compared to seven previously reported stimulation sweet spots and their relationship to the tract identified by the predictive feature map. Results: In the training cohort, structural connectivity between the VTA and dentato-rubro-thalamic tract (DRTT) correlated with contralateral tremor improvement (R = 0.41; p < 0.0001). The same connectivity profile predicted outcomes in a separate validation cohort (R = 0.59; p = 0.028). The predictive feature map represented the anatomical course of the DRTT, and all seven analyzed sweet spots overlapped the predictive tract (DRTT). Conclusions: Our results strongly support the possibility that structural connectivity is a predictor of contralateral tremor improvement in ET DBS. The results suggest the future potential for a patient-specific functionally based surgical target. Finally, the results showed convergence in “sweet spots” suggesting the importance of the DRTT to the outcome.

INTRODUCTION: The globus pallidus internus (GPi) region has evolved as a potential target for deep brain stimulation (DBS) in Parkinson's disease (PD). DBS of the GPi (GPi DBS) is an established, safe and effective method for addressing many of the motor symptoms associated with advanced PD. It is important that clinicians fully understand this target when considering GPi DBS for individual patients. METHODS: The literature on GPi DBS in PD has been comprehensively reviewed, including the anatomy, physiology and potential pitfalls that may be encountered during surgical targeting and post-operative management. Here, we review and address the implications of lead location on GPi DBS outcomes. Additionally, we provide a summary of randomized controlled clinical trials conducted on DBS in PD, together with expert commentary on potential applications of the GPi as target. Finally, we highlight future technologies that will likely impact GPi DBS, including closed-loop adaptive approaches (e.g. sensing-stimulating capabilities), advanced methods for image-based targeting and advances in DBS programming, including directional leads and pulse shaping. RESULTS: There are important disease characteristics and factors to consider prior to selecting the GPi as the DBS target of PD surgery. Prior to and during implantation of the leads it is critical to consider the neuroanatomy, which can be defined through the combination of image-based targeting and intraoperative microelectrode recording strategies. There is an increasing body of literature on GPi DBS in patients with PD suggesting both short- and long-term benefits. Understanding the GPi target can be useful in choosing between the subthalamic (STN), GPi and ventralis intermedius nucleus as lead locations to address the motor symptoms and complications of PD. CONCLUSION: GPi DBS can be effectively used in select cases of PD. As the ongoing DBS target debate continues (GPi vs. STN as DBS target), clinicians should keep in mind that GPi DBS has been shown to be an effective treatment strategy for a variety of symptoms, including bradykinesia, rigidity and tremor control. GPi DBS also has an important, direct anti-dyskinetic effect. GPi DBS is easier to program in the outpatient setting and will allow for more flexibility in medication adjustments (e.g. levodopa). Emerging technologies, including GPi closed-loop systems, advanced tractography-based targeting and enhanced programming strategies, will likely be future areas of GPi DBS expansion. We conclude that although the GPi as DBS target may not be appropriate for all PD patients, it has specific clinical advantages.

OBJECTIVE: Few studies have reported long-term outcomes of globus pallidus internus (GPi) deep brain stimulation (DBS) in Parkinson's disease (PD). The authors aimed to investigate long-term outcomes of bilateral GPi DBS for 5 years and beyond for PD patients. METHODS: The authors retrospectively analyzed the clinical outcomes in 65 PD patients treated with bilateral GPi DBS at a single center. The outcome measures of motor symptoms and health-related quality of life (HRQoL) included the Unified Parkinson's Disease Rating Scale (UPDRS) and the Parkinson's Disease Questionnaire (PDQ-39). Scores at baseline were compared with those at 1, 3, 5, and 6-8 years after implantation using Wilcoxon signed-rank tests with α correction. RESULTS: GPi DBS significantly improved the off-medication UPDRS III total scores, UPDRS IV, and dyskinesia score at 1 year when compared with baseline (all p < 0.001). The off- and on-medication tremor scores, UPDRS IV, and dyskinesia scores showed moderate and sustained improvement (the ranges of the mean percentage improvement at each time point were 61%-75%, 30%-80%, 29%-40%, and 40%-65%, respectively) despite lacking statistical significance at long-term follow-up with diminishing sample sizes. The off-medication UPDRS III total scores did not show significant improvement at 5 years or later, primarily because of worsening in rigidity, akinesia, speech, gait, and postural stability scores. The on-medication UPDRS III total scores also worsened over time, with a significant worsening at 6-8 years when compared with baseline (p = 0.008). The HRQoL analyses based on the PDQ-39 revealed significant improvement in the activities of daily living and discomfort domains at 1 year (p = 0.003 and 0.006, respectively); however, all the domains showed gradual worsening at the later time points without reaching statistical significance. At 3 years, the communication domain showed significant worsening compared with baseline scores (p = 0.002). CONCLUSIONS: GPi DBS in PD patients in this single-center cohort was associated with sustained long-term benefits in the off- and on-medication tremor score and motor complications. HRQoL and the cardinal motor symptoms other than tremor may worsen gradually in the long term. When counseling patients, it is important to recognize that benefits in tremor and dyskinesia are expected to be most persistent following bilateral GPi DBS implantation.

Management of patients with Parkinson disease (PD) during inpatient hospital stays is complex and poses unique challenges for physicians and ancillary staff. Patients with PD have a high risk of complications, encephalopathy, and prolonged hospital stay. Early recognition of complications and implementation of rehabilitation strategies along with appropriate management of medications are critical to improve outcomes. Patients with PD can exhibit worsening mobility and balance, insomnia, orthostatic hypotension, multiple neuropsychiatric symptoms, and gastrointestinal dysfunction while hospitalized. This review summarizes the specific in-hospital concerns observed in patients with PD and discusses potential treatment approaches.

Objective: To examine the short- and long-term clinical outcomes of the bilateral subthalamic nucleus (STN) and globus pallidus internus (GPi) deep brain stimulation (DBS) on gait and axial symptoms in Parkinson's disease (PD) patients. Available data have been inconsistent and mostly short-term regarding the effect of both brain targets on gait and axial symptoms. We aimed to identify potential target specific differences at 3-year follow-up from a large single-center experience. Methods: We retrospectively reviewed short-term (6-month follow-up) and long-term (36-month follow-up) changes in the Unified Parkinson's Disease Rating Scale (UPDRS) Part II and III total scores of 72 PD patients (53 with bilateral STN-DBS and 19 with bilateral GPi-DBS). An interdisciplinary team made target-specific decisions for each DBS patient. We analyzed changes in gait and axial subscores derived from UPDRS II and III. Results: In both the STN- and GPi-DBS cohorts, we observed no significant differences in gait and axial UPDRS derived subscores in the off-med/on stimulation state at long-term follow-up when compared to baseline. On-med axial scores remained similar in the short-term but worsened in both groups (STN, 2.23 ± 3.43, p < 0.001; GPi, 2.53 ± 2.37, p < 0.01) in the long-term possibly due to disease progression. At long-term follow-up, the UPDRS III off-med/on stimulation scores worsened but were persistently improved from baseline in both groups (-9.07 ± 13.9, p < 0.001). Conclusions: The study showed that long-term both STN- and GPi-DBS had a similar effect on gait and axial symptoms in UPDRS derived subscores at 36-month follow-up despite potential baseline differences in criteria for selection of each target. More sophisticated measures of gait and balance beyond the categorical UPDRS score will be needed for future studies.

BACKGROUND: Long-term efficacy of deep brain stimulation (DBS) on health-related quality-of-life (HRQoL) for isolated dystonia is not well established. This study aims to determine the long-term impact of DBS on HRQoL outcomes and identify clinical predictors. METHODS: We retrospectively investigated 16 inherited or idiopathic isolated dystonia patients treated with bilateral globus pallidus internus DBS who were followed beyond 9 years at our center. The cohort consisted of 9 males, 7 females; 10 generalized, 6 segmental; mean (range) age at implantation, 37.0 (8-67) years; mean follow-up duration after implantation, 10.9 (9-13) years. We employed the Unified Dystonia Rating Scale for motor and Short Form Health Survey for HRQoL assessments to monitor the change longitudinally. We analyzed the changes in motor and HRQoL at 1-2 years (short-term) and ≥9 years (long-term) follow-up as compared to baseline with a Wilcoxon signed-rank test. We assessed the factors that predicted motor and HRQoL improvement with univariate regression analyses. RESULTS: Motor (41.6%; p = 0.004) and HRQoL (total score, p = 0.039) improvements remained significant at long-term follow-up and, in the regression analysis, change in HRQoL outcomes correlated significantly with change in motor outcomes (R2 = 0.384, p = 0.010). Additionally, short-term motor and HRQoL improvements predicted the long-term motor (R2 = 0.384, p = 0.010) and HRQoL (total score, R2 = 0.594, p < 0.001) outcomes, respectively. CONCLUSION: Motor and HRQoL improvements with DBS in isolated dystonia remain sustained for nearly a decade and may largely be predictable by the short-term response to DBS.

Voxel-based analysis (VBA) of diffusion tensor images (DTI) and voxel-based morphometry (VBM) in patients with multiple sclerosis (MS) can sensitively detect occult tissue damage that underlies pathological changes in the brain. In the present study, both at the start of fingolimod and post-four months clinical remission, we assessed four patients with MS who were evaluated with VBA of DTI, VBM, and fluid-attenuated inversion recovery (FLAIR). DTI images for all four patients showed widespread areas of increased mean diffusivity (MD) and decreased fractional anisotropy (FA) that were beyond the highintensity signal areas across images. After four months of continuous fingolimod therapy, DTI abnormalities progressed; in particular, MD was significantly increased, while brain volume and high-intensity signals were unchanged. These findings suggest that VBA of DTI (e.g., MD) may help assess MS demyelination as neuroinflammatory conditions, even though clinical manifestations of MS appear to be in complete remission during fingolimod.

Background: Voice and speech disorders are one of the most important issues after subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson's disease (PD) patients. However, articulation features in this patient population remain unclear. Objective: We studied the articulation features of PD patients with STN-DBS. Methods: Participants were 56 PD patients treated with STN-DBS (STN-DBS group) and 41 patients treated only with medical therapy (medical-therapy-alone group). Articulation function was evaluated with acoustic and auditory-perceptual analyses. The vowel space area (VSA) was calculated using the formant frequency data of three vowels (/a/, /i/, and /u/) from sustained phonation task. The VSA reportedly reflects the distance of mouth/jaw and tongue movements during speech and phonation. Correlations between acoustic and auditory-perceptual measurements were also assessed. Results: The VSA did not significantly differ between the medical-therapy-alone group and the STN-DBS group in the off-stimulation condition. In the STN-DBS group, the VSA was larger in the on-stimulation condition than in the off-stimulation condition. However, individual analysis showed the VSA changes after stopping stimulation were heterogeneous. In total, 89.8 of the STN-DBS group showed a large VSA size in the on- than in the off-stimulation condition. In contrast, the VSA of the remaining patients in that group was smaller in the on- than the off-stimulation condition. Conclusions: STN-DBS may resolve hypokinesia of the articulation structures, including the mouth/jaw and tongue, and improve maximal vowel articulation. However, in the on-stimulation condition, the VSA was not significantly correlated with speech intelligibility. This may be because STN-DBS potentially affects other speech processes such as voice and/or respiratory process.

Speech and voice disorders are one of the most common adverse effects in Parkinson’s disease (PD) patients treated with subthalamic nucleus deep brain stimulation (STN-DBS). However, the pathophysiology of voice and laryngeal dysfunction after STN-DBS remains unclear. We assessed 47 PD patients (22 treated with bilateral STN-DBS (PD-DBS) and 25 treated medically (PD-Med); all patients in both groups matched by age, sex, disease duration, and motor and cognitive function) using the objective and subjective voice assessment batteries (GRBAS scale and Voice Handicap Index), and laryngoscopy. Laryngoscopic examinations revealed that PD-DBS patients showed a significantly higher incidence of incomplete glottal closure (77 vs 48 %; p = 0.039), hyperadduction of the false vocal folds (73 vs 44 %; p = 0.047), anteroposterior hypercompression (50 vs 20 %; p = 0.030) and asymmetrical glottal movement (50 vs 16 %; p = 0.002) than PD-Med patients. On- and off-stimulation assessment revealed that STN-DBS could induce or aggravate incomplete glottal closure, hyperadduction of the false vocal folds, anteroposterior hypercompression, and asymmetrical glottal movement. Incomplete glottal closure and hyperadduction of the false vocal folds significantly correlated with breathiness and strained voice, respectively (r = 0.590 and 0.539). We should adjust patients’ DBS settings in consideration of voice and laryngeal functions as well as motor function.

Voice and speech disorders are one of the most important issues after subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson’s disease patients; however, their characteristics remain unclear. We performed a comprehensive voice evaluation including the multi-dimensional voice program for acoustic analysis, the GRBAS scale for perceptual analysis, and the evaluation of the voice handicap index (VHI) for psychosocial analysis. In total, 68 patients who had undergone STN-DBS (37 assessed in the on- and off-stimulation conditions) and 40 who had been treated with medical therapy alone were evaluated. Further, we performed laryngoscopic examinations in 13 STN-DBS and 19 medical-therapy-alone patients. The STN-DBS group, especially females, showed widespread impairment of voice parameters and significantly poorer VHI scores than the medical-therapy-alone group. The degree of voiceless (DUV) and strained voice were the most impaired factors in the STN-DBS group; and DUV significantly improved after stopping stimulation. Furthermore strained voice, breathiness, and asthenia improved after stopping stimulation. Laryngoscopic examination showed that abnormal laryngeal muscle contraction and incomplete glottal closure were more prominent in the STN-DBS group than in the medical-therapy-alone group. We demonstrated that (1) more widespread voice impairment in females, (2) poorer voice-related QOL, (3) worse DUV and strained voice, and (4) abnormal laryngeal muscle contraction were the characteristic voice and laryngeal findings in the STN-DBS group compared with those in the medical-therapy-alone group.

Objectives: We assessed the usefulness of differential diagnosis of parkinsonism by evaluating lesions of the decussation of the superior cerebellar peduncle (SCP) in patients with progressive supranuclear palsy (PSP) using a new MRI procedure known as readout segmentation of long variable echo-trains (RESOLVE). Methods: We evaluated 100 cases, consisting of 20 with PSP, 24 with Parkinson's disease (PD), 13 with multiple system atrophy with predominant parkinsonism (MSA-P), 18 with multiple system atrophy with predominant cerebellar ataxia (MSA-C), and 24 controls. All patients were scored on the Unified Parkinson's Disease Rating Scale Part III and the Scale for the Assessment and Rating Scale of Ataxia, and MRI using RESOLVE was conducted. Results: Images acquired by this MRI procedure clearly showed high intensity areas corresponding to the decussation of the SCP in all controls, PD, and MSA patients. In contrast, ten of the 20 PSP patients exhibited abnormal iso intensities of the decussation of the SCP, while the other 10 showed high intensity signals. Among the PSP patients, there were no differences in clinical features between those with and those without visualization of the decussation of the SCP. Iso intensity signals had a sensitivity of 50% and a specificity of 100% for differentiating PSP from PD, MSA, and controls. Conclusion: This MRI procedure (RESOLVE) shows a potential for detecting the involvement of the decussation of the SCP in PSP, and can be used for discriminating PSP from PD and MSA-P. © 2013 Elsevier Ltd.

Background: The aim of this study was to investigate the cortical and subcortical brain structures in Parkinson's disease (PD) with visual hallucination (VH), and to elucidate the association between the proposed hypothesis of VH in PD and regional brain volume changes. Methods: We used 3T magnetic resonance imaging (MRI) and voxel-based morphometry (VBM) to investigate the brain structures of PD patients with VH (PD-VH; n=13) and PD patients without VH (PD-C; n=13). Results: The PD-VH patients showed significant cortical atrophy compared to the PD-C patients in the bilateral dorsolateral prefrontal cortex, left rostral region of the prefrontal cortex, left ventral section of the cingulate cortex, bilateral primary visual cortex, and secondary visual cortex including the left inferior occipital gyrus, right lingual cortex, right supramarginal gyrus, and left fusiform gyrus. Significant subcortical atrophic changes were observed in the white matter of the right parahippocampal gyrus, the bilateral posterior part of the cingulate gyrus, the left lingual gyrus, and the right middle occipital gyrus. Conclusions: VH in PD can occur due to distinctive neuroanatomical involvement. © 2013 Movement Disorder Society.

This symposium discusses the utility of the different MR techniques in the diagnosis and management of spinocerebellar degeneration (SCD). Conventional MRI is widely used and can show characteristic signal abnormalities such as putaminal hyperintensity, hyperintense putaminal rim, putaminal hypointensity, hot cross bun sign in the pontine base, and hyperintensity in the middle cerebellar peduncles strengthening a diagnosis of multiple system atrophy (MSA). However, the diagnostic utility of these signal abnormalities in early MSA remains restricted. In addition, it should be considered that different magnetic field strengths and sequences could be influenced on the findings resulting false negative. On the other hand, proton magnetic resonance spectroscopy, diffusion weighted imaging (DWI), diffusion tensor imaging (DTI) and voxel based morphometry (VBM) in the pontine base, cerebellum, and putamen will be informative in the early diagnosis of MSA and other SCD prior to conventional MRI changes and even before any clinical manifestation of symptoms. Particularly, DWI, DTI, and VBM are expected to have potential as surrogate markers of disease progression. Further prospective and large studies including earlier disease stages will be needed to clarify whether these novel MR techniques will aid in the future sets of diagnostic criteria and therapeutic trials.

We investigated the magnetic resonance imaging (MRI) findings of 32 multiple sclerosis (MS) patients using voxel-based morphometry (VBM) and voxel-based analysis of white matter fluid-attenuated inversion recovery image (FLAIR) high-intensity lesions and diffusion tensor imaging (DTI). Compared with 18 healthy controls, MS patients showed gray matter volume reduction in the thalamus, hypothalamus, caudate, limbic lobe, and frontal lobe. A marked volume reduction of white matter was evident along the ventriculus lateralis and corpus callosum. FLAIR high-intensity lesions were observed beside the ventriculus lateralis. DTI revealed reduced fractional anisotropy areas similar to those of the FLAIR high-intensity lesions. Changes in the volume of increased mean diffusivity (MD) were the most widespread and extended to normal-appearing white matter (p < 0.001). Multiple regression analysis revealed that MD values were significantly correlated with both disease duration (r = 0.381, p = 0.032) and expanded disability status scale scores (EDSS) (r = 0.393, p = 0.026). This study demonstrated that combined voxel-based analysis for volumetry, FLAIR high-intensity lesions, and DTI could reveal widespread brain abnormalities in MS patients. Furthermore, DTI, especially MD, showed far more widespread brain degeneration than other MRI parameters, and was significantly correlated with both severity and disease duration. © 2012 Elsevier B.V.

＜文献概要＞はじめに 首下がり症候群は,体幹に比して頸部が異常に前屈した状態を呈する疾患群を指す(図1).高橋は,「いくつかの基礎疾患に伴ってみられる症候としての首下がり」を首下がり症候群とした.首下がり症候群は,神経筋疾患が原因となる場合,神経変性疾患が原因となる場合,さらには脊椎・脊髄病変が原因となる場合に大別される(図1).一方,"首下がり"は,神経学用語集改訂第3版において,「三浦謹之助が詳述した項部筋不全麻痺による首下がりを主徴とする病態.当初地方病[Gerlier病]とされたが諸原因による」との記載がある.三浦の報告した「Kubisagari」で認めた頸部の前屈は,発作性,麻痺性,再発性で,しばしば家族性であるなど,現在,われわれが診療している首下がり症候群とは臨床像が大きく異なる.このため,目崎は,その総説の中で,dropped headを首下がりと訳すことに対して異を唱えている.この過度の頸部の前屈が,錐体外路疾患において注目されるようになったのは比較的最近であり,用語についてもその成因をジストニアと考えたことに由来するdisproportionate anterocollisや,筋力低下と考えたことに由来するdropped head syndrome(首下がり症候群)が用いられてきた.本レビューでは,錐体外路疾患におけるdisproportionate anterocollis(antecollis)・首下がり症候群の病態,分類,治療について整理したい.

＜文献概要＞はじめに 首下がり症候群は,体幹に比して頸部が異常に前屈した状態を呈する疾患群を指す(図1).高橋は,「いくつかの基礎疾患に伴ってみられる症候としての首下がり」を首下がり症候群とした.首下がり症候群は,神経筋疾患が原因となる場合,神経変性疾患が原因となる場合,さらには脊椎・脊髄病変が原因となる場合に大別される(図1).一方,"首下がり"は,神経学用語集改訂第3版において,「三浦謹之助が詳述した項部筋不全麻痺による首下がりを主徴とする病態.当初地方病[Gerlier病]とされたが諸原因による」との記載がある.三浦の報告した「Kubisagari」で認めた頸部の前屈は,発作性,麻痺性,再発性で,しばしば家族性であるなど,現在,われわれが診療している首下がり症候群とは臨床像が大きく異なる.このため,目崎は,その総説の中で,dropped headを首下がりと訳すことに対して異を唱えている.この過度の頸部の前屈が,錐体外路疾患において注目されるようになったのは比較的最近であり,用語についてもその成因をジストニアと考えたことに由来するdisproportionate anterocollisや,筋力低下と考えたことに由来するdropped head syndrome(首下がり症候群)が用いられてきた.本レビューでは,錐体外路疾患におけるdisproportionate anterocollis(antecollis)・首下がり症候群の病態,分類,治療について整理したい.

パーキンソン病(PD)に対する言語療法はLee Silverman Voice Treatmentが嚆矢となり,その後に病態解明や治療法の開発が進んできた.本稿では,米国のParkinson Voice Project(PD専門の言語治療クリニック)で行われている治療法を中心に紹介する.本施設ではPDにより低下した発声・発話機能の回復を目的とした個別療法と,改善した発声・発話機能の維持を目的とした集団療法の2つの治療プログラムが提供されている.いずれの治療法においてもPD患者が日常生活で良好な発話が保てるよう緻密に構想化されたアプローチのみならず,患者のモチベーションを高めるための創意工夫が随所に施されていた.(著者抄録)

視床下核脳深部刺激療法(STN-DBS)後、長期治療中に再増悪した運動合併症に対し、ロピエロール徐放錠が有効であった2例を経験した。症例1は56歳女で、44歳時に両上肢静止時振戦で発症した。薬物療法の調整は困難と判断し、52歳時に両側STN-DBSを施行した。刺激の調整による運動症状のロントロールは、刺激部位の変更や刺激強度の変更により、ジスキネジアの増悪、複視、手足のしびれなどが出現した。ロピニロール徐放錠へと切り替えたところ、ジスキネジアの増悪を伴うことなく軽度改善した。症例2は54歳女で、38歳時に両上肢静止時振戦で発症した。47歳時に左STN-DBSを施行した。左側への側前屈が増悪したため、ロピニロール徐放錠へと切り替えた。直後は動きの悪化を訴えたが、姿勢異常の軽度から中等度改善を認めた。
