This study aimed to elucidate the role of sex in neurocognitive function in patients with Parkinson’s disease (PD). Ninety-four idiopathic PD and 167 healthy elderly as normal controls (NCs) were recruited and underwent comprehensive neuropsychological assessments. The sex difference were found in NCs but not in PD. In male, PD patients had worse performance on the Digit symbol substitution (DSS) (p

BACKGROUND Social functioning is crucial for the determinants of Parkinson's disease (PD) with dementia; however, there is no social functioning scale applicable to PD. OBJECTIVE This study aimed to develop a social functioning scale specific to PD (PDSFS) and provide a cut-off score to improve diagnosis accuracy. METHODS The items were developed through literature, interview patients, and PD expertise. After the pilot study, one hundred fifty-seven patients and 74 healthy participants were enrolled and completed the Mini-Mental State Examination, Clock Drawing Test, Activities of Daily Living, Neuropsychiatric Inventory, Adaptive Behavior Assessment System-Second Edition (ABAS-II) and part III of the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS). RESULTS The final PDSFS has 23 items. The exploratory factor analysis revealed three factors, including "Family Life, Hobbies and Self-Care", "Interpersonal Relationship and Recreational Leisure", and "Social Bond". The internal consistency coefficient was 0.883, and the test-retest reliability was 0.774, respectively. The total score of the PDSFS was significantly related to the total score of ABAS-II (r = 0.609, p

Spasticity and pain in the masticatory muscles or mouth opening limitation have been reported as early signs and symptoms of amyotrophic lateral sclerosis (ALS). These signs and symptoms are also frequently seen in, and thus mistaken for, temporomandibular disorders (TMD).The authors report a case of ALS initially presenting with signs and symptoms of TMD. The TMD was followed by dysarthria of insidious onset, leading to the diagnosis of ALS. This case highlights the importance of considering TMD as a potential early form of presentation of ALS, requiring multidisciplinary treatment, especially by dental professionals.A review of the literature was conducted to elucidate the oral and facial signs and symptoms of ALS and to identify ways of improving the quality of life of patients through a multidisciplinary approach.

Patients with parkinsonism or other movement disorders may visit the emergency department due to acute deterioration of neurological status or consciousness disturbance. Under such circumstances, patients may be misdiagnosed as having a hyperacute stroke, i.e. stroke mimic. The purpose of the present study was to explore the clinical features and consequences of patients with parkinsonism or other movement disorders presenting as stroke mimics with activation of a stroke code.In this retrospective case-series study, we reviewed the charts and stroke code registry data in two stroke centers with high volume of stroke codes and thrombolytic therapy in the Southern Taiwan.We found seven male patients (67.0 ± 12.8 years old): one with focal myoclonus, one with focal dystonia, and the other five with parkinsonism. The chief problems for emergency department visit included acute consciousness disturbance in one patient and motor weakness in other six patients. Five of the six patients with motor weakness complained unilateral symptoms. Six patients were evaluated by neurology residents (five by second-year residents, one by a third-year resident) and one by a board-certified neurologist, while a misdiagnosis of a stroke was made in three patients. All patients experienced neurological improvement when follow-up. One patient who received intravenous thrombolytic therapy had no intracranial hemorrhagic complications.Although rare, parkinsonism or other movement disorders may present as a stroke mimic with activation of a stroke code. Consulting neurologists should clarify the etiology for those patients with acute consciousness disturbance or motor weakness and avoid unnecessary thrombolysis. Key Words: Parkinson disease, parkinsonism, movement disorders, stroke code, thrombolysis.

Internal responsiveness of HRQoL in the stable patient group. (DOCX 20 kb)

Objectives Generic and disease-specific health-related quality of life (HRQoL) instruments may reflect different aspects of lives in patients with Parkinson’s disease (PD) and thus be associated with different determinants. We used the same cluster of predictors for the generic and disease-specific HRQoL instruments to examine and compare the determinants of HRQoL. Method HRQoL was measured in 92 patients with PD by the 36-item Short-Form Health Survey (SF-36) and the 39-item Parkinson’s Disease Questionnaire (PDQ-39). The predictors included demographic and disease characteristics, and motor and non-motor symptoms. Multiple regression analyses were used to identify HRQoL determinants. Results Depressive symptoms and motor difficulties of daily living were the first two significant determinants for both instruments. The other significant determinant for the SF-36 was fatigue and non-motor difficulties of daily living, and for the PDQ-39 was motor signs of PD. Conclusions The results suggest the importance of the evaluation and intervention focused on depressive symptoms and motor difficulties of daily living in patients with PD. In addition, the SF-36 seems more related to non-motor symptoms, while the PDQ-39 appears more associated with motor symptoms. This information is important for understanding results from these two instruments and for choosing which to use.

Changed scores of measures in three groups. (DOCX 17 kb)

Proprioceptive deafferentation of spinal cord origin can cause pseudoathetosis, sensory ataxic gait, or both. The co-existence of pseudoathetosis and sensory ataxic gait caused by a surgically treatable condition of the spinal cord has been rarely reported. An 80-year-old man with cervical spondylotic myelopathy presented with severe sensory ataxic gait which confined him to a wheelchair. He also had poor control of his hands due to the pseudoathetoid movements of the fingers, which prevented him from sustaining constant muscle contraction. He underwent C3-4 and C4-5 anterior discectomies and anterior fusion. His neurological deficits gradually improved after the decompressive surgery. About 7months postoperatively, he was totally independent in activities of daily living and needed no mobility aid. This case highlights the clinical importance of recognizing a surgically treatable and reversible condition of the spinal cord that causes pseudoathetosis and sensory ataxic gait.
