To clarify the neural correlates and brain activity during the progression of human non-rapid eye movement (NREM) sleep, we examined the absolute regional cerebral blood flow (rCBF) during light and deep NREM sleep and during wakefulness in normal humans using positron emission tomography with H(2)(15)O. Relative changes in rCBF during light and deep NREM(More)
To examine clinical features of cases of death among epilepsy patients as a case-control study, with special attention to suicide, we analyzed the records of 43 deceased patients with well-classified epilepsy. The subjects were compared with 1,722 control patients who showed definite subtypes of epilepsy. As a result, among the major causes of death, 13 of(More)
OBJECTIVE To evaluate which variables predict interictal psychosis in epilepsy. METHODS The authors reviewed the biological backgrounds, clinical characteristics, and EEG findings in 246 patients with epilepsy and interictal psychosis and in 658 control patients with epilepsy and no psychotic history. With a logistic regression approach, the significance(More)
Persons with epilepsy experience déjà vu phenomena with or without seizure recognition. Déjà vu experiences are also common mental phenomena in nonclinical individuals. The purpose of this study was to clarify two forms of déjà vu experiences in persons with epilepsy. Déjà vu experiences of 312 patients with epilepsy and 402 nonclinical individuals were(More)
PURPOSE To evaluate further the relevance of designating psychotic episodes as either postictal or interictal, we compared several biologic variables between epilepsy patients with and without psychosis. METHODS The study subjects comprised 282 patients with psychosis (36 with postictal psychosis, 224 with interictal psychosis, and 22 with both postictal(More)
PURPOSE To ascertain whether bimodal psychosis (i.e., independent postictal and interictal psychosis) in patients with epilepsy can be characterized by postictal psychosis that develops after interictal psychosis remits. METHODS We reviewed the records of 14 patients with bimodal psychosis treated at a national center hospital. Clinical and(More)
Delta wave deficits during sleep have been observed in patients with schizophrenia. Decreased slow-wave sleep is reported to be associated with negative symptoms. Frontal lobe dysfunction is also believed to underlie negative symptoms of schizophrenia. This study was designed to identify functional abnormalities in schizophrenia manifested on patients'(More)
Basophilic inclusions (BIs) are pathological features of a subset of frontotemporal lobar degeneration disorders, including sporadic amyotrophic lateral sclerosis (ALS) and familial ALS (FALS). Mutations in the fused in sarcoma/translocated in liposarcoma (FUS/TLS) gene have recently been identified as a cause of FALS. The FUS/TLS-immunoreactive inclusions(More)
This study aimed to identify brain regions with the least decreased cerebral blood flow (CBF) and their relationship to physiological parameters during human non-rapid eye movement (NREM) sleep. Using [(15)O]H(2)O positron emission tomography, CBF was measured for nine normal young adults during nighttime. As NREM sleep progressed, mean arterial blood(More)
Migraine-like features sometimes characterize the headache that follows epileptic seizure (postictal headache, PIH). We compared patients with different types of epilepsy to investigate the association between migraine-like PIH and seizure type. Subjects comprised 364 patients with partial epilepsy. Epilepsy types were temporal lobe epilepsy (TLE, n = 177),(More)
