BACKGROUND Causative role of encephalitis in major psychotic features, dyskinesias (particularly orofacial), seizures, and autonomic and respiratory changes has been recently emphasized. These symptoms often occur in young females with ovarian teratomas and are frequently associated with serum and CSF autoantibodies to the NMDA receptor (NMDAR). METHODS(More)
BACKGROUND The occurrence of duplications of the amyloid precursor protein gene (APP) has been described in European families with early-onset familial Alzheimer disease (EO-FAD) and cerebral amyloid angiopathy. However, the contribution of APP duplication to the development of AD in other ethnic populations remains undetermined. METHODS The occurrence of(More)
A 65-year-old man presented with bilateral postural hand tremor (3 Hz) followed by memory impairment, which improved spontaneously after admission to our hospital. Two weeks after admission, he had another bout of memory impairment and complained of insomnia. Brain magnetic resonance imaging (MRI) showed a signal intensity change in the medial part of the(More)
Recent CSF and postmortem brain hypocretin measurements in human narcolepsy suggest that hypocretin deficiency is involved in the pathophysiology of the disease. Thus, it is important to study whether neurological disorders also have abnormal CSF hypocretin levels. We therefore measured hypocretins in the CSF of various neurological disorders and(More)
Patients with multiple system atrophy (MSA) frequently exhibit orthostatic hypotension (OH). Leptin, an adipose-derived hormone, contributes to the sympathetic control of blood pressure (BP), and loss of leptin may cause OH. We aimed to clarify the relationship between leptin and OH in MSA. Serum leptin levels were measured in 36 patients with MSA, 25(More)
We reported a case with Kennedy-Alter-Sung syndrome (KAS) associated with bilateral external ophthalmoplegia. The patient had movement disturbance of bilateral infra-oblique muscles. The doll's eye phenomenon was not noted. It was suggested that the external ophthalmoplegia was due to the involvement of the oculomotor nucleus that innervated infra-oblique(More)
Patients with multiple system atrophy (MSA) often have evidence of compromised gastrointestinal motility. Ghrelin is a gut hormone that influences gastrointestinal motility in humans. The aim of this study was to determine whether ghrelin secretion is affected in MSA patients, and to investigate the relation between ghrelin secretion and gastrointestinal(More)
