To establish an early diagnosis of Alzheimer's disease (AD), we evaluated brain spatial dynamics and cognitive function in mild AD. Seventeen patients with the diagnosis of mild AD and 17 age-matched controls were examined for Omega (global complexity), Sigma (total power) and Phi (generalized frequency) by 19-channel electroencephalography (EEG). As a(More)
RATIONALE Both psychotropic drugs and mental disorders have typical signatures in quantitative electroencephalography (EEG). Previous studies found that some psychotropic drugs had EEG effects opposite to the EEG effects of the mental disorders treated with these drugs (key-lock principle). OBJECTIVES We performed a placebo-controlled pharmaco-EEG study(More)
To explore brain functions in schizophrenic patients, the global analytic strategy of multichannel EEG was performed that combines measures of global complexity (Omega), total power (Sigma) and generalized frequency (Phi), and EEG microstate analysis was applied to multichannel EEG data for 24 nonmedicated patients and 24 healthy subjects. The patients had(More)
Effects of four novel atypical antipsychotic drugs (olanzapine, perospirone, quetiapine, and risperidone) on scalp-recorded multi-channel EEGs were compared with two conventional antipsychotic drugs (chlorpromazine and haloperidol) and placebo in 14 healthy male volunteers. All subjects went through seven sessions. In each session, EEGs were recorded before(More)
The brain wave activity of a professional Salpuri dancer was observed while the subject recalled her performance of the Salpuri dance when sitting in a chair with closed eyes. As she recalled the feeling of the ecstatic trance state induced by the dance, an increase in alpha brain activity was observed together with marked frontal midline theta activity.(More)
To elucidate the role of ras gene mutations during the early stage of colorectal tumour progression, K-ras gene mutations were analysed in 32 benign adenomas and 36 adenomas with focal carcinoma in the colorectum by microscraping of histologically pure regions from tissue sections, polymerase chain reaction-restriction fragment length polymorphism and in(More)
BACKGROUND Vomiting is commonly encountered in clinical medicine. When organic gastrointestinal, metabolic, and brain diseases are ruled out, many cases are considered to be functional. We experienced an adult patient with epilepsy whose main symptom was vomiting. Biopsychosocial approaches were needed to control the symptoms. CASE PRESENTATION A(More)
We performed acupuncture treatment on first consultation for a female 28-year-old patient with severe axial dystonia, causing involuntary movement and abnormal posture of the neck and body, which had developed during treatment for schizophrenia. Involuntary movement involving elevation of the right shoulder began to occur in October X-1. Drugs were(More)
