Objective
Orthostatic hypotension (OH) is one of the most common autonomic dysfunctions in Parkinson’s disease (PD) patients. However, many patients with OH are asymptomatic. Conversely, orthostatic dizziness (OD) is not always associated with OH. We investigated the effects of positional changes on cerebral perfusion in patients with PD and OH.
Methods
We enrolled 42 patients, comprising 31 PD patients and 11 healthy controls. All the subjects underwent the following clinical assessments: the OH questionnaire, head-up tilt test (HUTT) with transcranial Doppler (TCD), near-infrared spectroscopy, measurement of the change in oxygenated hemoglobin (ΔHboxy) during the squat-to-stand test (SST), measurement of the time derivative of total hemoglobin (DHbtot), and time taken to reach the peak (peak time [PT]) of DHbtot after restanding.
Results
The mean flow velocity change (ΔMFV) in the TCD during the HUTT failed to differentiate between the PD-OH(+) and PD-OH(-) groups. The change in oxygenated hemoglobin ΔHboxy was greater in the PD-OH(+) group, which persisted for 9 min until the end of the HUTT only in the left hemisphere. During SST, PT was significantly delayed in the left hemisphere in PD-OH(+) patients.
Conclusion
Although TCD demonstrated no significant difference in ΔMFV, the parameters measured by near-infrared spectroscopy, such as ΔHboxy during HUTT and PT during the SST, significantly increased ΔHboxy or delayed PT in the left hemisphere of PD-OH(+). Positional changes have a detrimental effect on cerebral hemodynamics in patients with PD and OH, especially in the left hemisphere.

AbstractAbstract PDFSupplementary Material
Objective
Parkinson’s disease (PD) patients often find it difficult to visit hospitals because of motor symptoms, distance to the hospital, or the absence of caregivers. Telemedicine is one way to solve this problem.
Methods
We surveyed 554 PD patients from eight university hospitals in Korea. The questionnaire consisted of the clinical characteristics of the participants, possible teleconferencing methods, and preferences for telemedicine.
Results
A total of 385 patients (70%) expressed interest in receiving telemedicine. Among them, 174 preferred telemedicine whereas 211 preferred in-person visits. The longer the duration of disease, and the longer the time required to visit the hospital, the more patients were interested in receiving telemedicine.
Conclusion
This is the first study on PD patients’ preferences regarding telemedicine in Korea. Although the majority of patients with PD have a positive view of telemedicine, their interest in receiving telemedicine depends on their different circumstances.

AbstractAbstract PDFSupplementary Material
Movement disorders associated with glial fibrillary acidic protein (GFAP) autoantibodies have rarely been reported as ataxia or tremors. A 32-year-old man with headache and fever, initially diagnosed with viral meningoencephalitis, showed gradual improvement with empirical treatment. Two weeks after the illness, he suddenly developed orofacial, tongue, and neck dyskinesia accompanied by oculomotor abnormalities, which developed into severe generalized choreoballism. Brain magnetic resonance imaging (fluid-attenuated inversion recovery) showed signal hyperintensities in the bilateral globus pallidus interna. The clinical picture suggested an acute inflammatory trigger of secondary autoimmune encephalitis. The autoimmune antibody test was positive for GFAP, with the strongest reactivity in the cerebrospinal fluid (CSF) before treatment and decreased reactivity in serial CSF examinations during immunotherapy. Dyskinesia gradually improved to the extent that it could be controlled with only oral medications. This patient presented with parainfectious GFAP meningoencephalitis with distinctive clinical features and imaging findings.
