Patients with Parkinson's disease (PD) often suffer from sleep disturbances, including excessive daytime sleepiness (EDS) and rapid eye movement behavior disorder (RBD). These symptoms are also experienced by patients narcolepsy, which is characterized orexin neuronal loss. In PD, a decrease in neurons observed pathologically, but the association between disturbance PD cerebrospinal fluid (CSF) levels still unclear. This study aimed to clarify role of as biomarker PD. CSF samples were...
Abstract In Parkinson’s disease, a precursor phenomenon to visual hallucinations presents as ‘pareidolias’ which make ambiguous forms appear meaningful. To evoke and detect pareidolias in patients, noise pareidolia test was recently developed, although its task-dependent mechanisms are yet be revealed. When subjected this test, we hypothesized that patients exhibiting would show altered top-down influence of processing allowing us demonstrate the pareidolic illusionary behaviour disease...
Abstract The precise neural underpinnings of face pareidolia in patients with Parkinson’s disease (PD) remain unclear. We aimed to clarify recognition network abnormalities associated such patients. Eighty-three PD and 40 healthy controls were recruited this study. Patients classified into nonpareidolia groups. Volumetric analyses revealed no significant differences between the ( n = 39) 44) patient further observed decreased functional connectivity among regions interest bilateral...
Abstract ‘Yips’ in golf is a complex spectrum of anxiety and movement-disorder that affects competitive sporting performance. With unclear etiology high prevalence documented western literature, the perception management this psycho-neuromuscular problem among Japanese elite golfers unknown. The objective study was to explore factors associated with yips, investigate performance deficits strategies implemented prevent yips. We surveyed approx. 1300 professional on their golfing habits,...
Background: Pareidolias are visual phenomena wherein ambiguous, abstract forms or shapes appear meaningful due to incorrect perception. In Parkinson's disease (PD), patients susceptible hallucinations experience visuo-perceptual deficits in the form of pareidolias. Although pareidolias necessitate top–down modulation processing, cortical dynamics internally generated perceptual priors on these misperceptions is unknown. Objectives: To study prestimulus-related electroencephalography (EEG)...
Objectives: Runner's dystonia is a task-specific that occurs in the lower limbs and trunk, with diverse symptomatology. We aimed to identify origin of dystonic movement abnormality using combined three-dimensional kinematic analysis electromyographic (EMG) assessment during treadmill running. Participant: A 20-year-old female runner who complained right-foot collision left-leg right-leg swing-phase, which mimicked right-ankle focal dystonia. Results: Kinematic EMG her running motion was...
レボドパ/カルビドパ配合経腸用液（levodopa-carbidopa intestinal gel; LCIG）療法における経皮内視鏡的胃瘻腸瘻造設術（percutaneous endoscopic gastro-jejunostomy; PEG-J）の合併症について，自験例14例について検討した．10例（71.4％）において合併症が発生した．高圧アラームでの来院では，Jチューブの不具合解消による改善が3例（21.4％），ポンプ交換での改善が3例（21.4％）であった．重篤な消化器症状として2例（14.3％）では穿孔，腹膜炎，潰瘍が認められた．胃瘻部の皮膚症状は7例（50.0％）であり，LCIG療法では，PEG-J関連合併症への対策が重要であることが示唆された．
Abstract ‘Yips’ is an involuntary movement disorder seen in some professional golfers. The diagnostic challenge yips to distinguish symptoms of task-specific dystonia from psychological ‘choking’. We hypothesized that mild-yips golfers, the yips-like shots demonstrate features are distinguishable normal-shots allowing for objective classification. 15 golfers with subjective complaints were assessed via motion-capture and surface electromyography during a ‘putting’ task. Normal-hits...
Abstract Background Parkinson’s disease (PD) patients susceptible to visual hallucinations experience perceptual deficits in the form of pareidolias. While pareidolias necessitate top-down modulation processing, cortical dynamics internally generated priors on pareidolic misperceptions is unknown. Objectives To study pre-stimulus related EEG spectral and network abnormalities PD experiencing Methods 21 in-patients 10 age-matched healthy controls were evaluated. Neuropsychological assessments...
Abstract ‘Yips’ is an involuntary movement disorder seen in some professional golfers. The diagnostic challenge yips to distinguish symptoms of task-specific dystonia from psychological ‘choking’. We evaluated 15 golfers with mild symptomatic via anxiety tests, motion-capture and surface electromyography during a ‘putting’ task. Movement instabilities were analyzed temporal statistical methodologies (one-dimensional parametric mapping). In subset golfers, we found significant differences...
症例は68歳，男性．20歳時に十二指腸潰瘍により幽門側胃切除術，Billroth II法再建後であった．57歳時にパーキンソン病と診断され薬物治療が開始された．薬剤調整を行ったが日常生活に支障をきたすウェアリングオフとジスキネジアを認めるようになった．レボドパ/カルビドパ配合経腸用液（levodopa-carbidopa intestinal gel; LCIG）療法導入を検討したが，腹壁癒着により経皮内視鏡的胃瘻造設術は施術困難であった．そのため，開腹胃瘻造設術によりLCIG療法導入し，経過は良好であった．本例は開腹胃瘻造設術によりLCIG療法を導入した本邦初の報告である．
Abstract Background Yips in golf is a complex spectrum of psychological anxiety and movement disorder that affects competitive sporting performance. Existing literature limited to several western studies the manifestations this problem Japanese golfers currently unknown. Objective To quantify self-reported perception manifestation yips among from professional golfers’ association (PGA). Methods We analyzed 1271 (of 1356) elite cross-sectional manner. Golfers were sensitized beforehand about...
