A population survey of seasonality in six representative cities in Japan was conducted using the Japanese version of the Seasonal Pattern Assessment Questionnaire (SPAQ). The questionnaires were given to 951 parents (male: female ratio 1:1 age range 34-59 years) of high-school students. Significant regional differences in seasonal variations of mood, length(More)
Effects of a new lighting stimulation system upon subjective sleep and waking feeling were psychophysiologically examined in 24 healthy students in order to develop a way of obtaining comfortable awakening. The subjects underwent three different experimental conditions: the light stimulation condition, non-light stimulation condition and the control(More)
BACKGROUND To differentiate the features of electroencephalography (EEG) after status epileptics in febrile children with final diagnosis of either febrile seizure (FS) or acute encephalopathy for an early diagnosis. METHODS We retrospectively collected data from 68 children who had status epilepticus and for whom EEGs were recorded within 120 h. These(More)
A 12-year-old girl presented with talipes equinus of both legs, attenuation of upper and lower limb tendon reflexes, thermal hyperalgesia, and reduction of vibratory sensation. On clinical examination, muscle twitches of fingers of both hands, as well as the abductor halluces and the dorsal interossei muscles of the right foot were observed. Nerve(More)
The ability to fix the eyes on a target, visual fixation, is important for the maintenance of equilibrium. The visual suppression (VS) test is one method of measuring the function of visual fixation. The test records caloric nystagmus by electrooculography, and the maximum slow phase velocity of caloric nystagmus in darkness is compared with the slow phase(More)
Electromyographic artifacts are sometimes misinterpreted as epileptic discharges in scalp electroencephalograms (EEGs). In addition, the distribution of the epileptic discharges near the earlobe is often distorted by earlobe activation; therefore, these epileptic discharges may not be correctly diagnosed. Here, we report a case of palatal tremor in which(More)
PURPOSE To clarify the relationship between macrocephaly and neurodevelopmental disorders, as well as identify the prevalence of PTEN mutations in autism spectrum disorders with macrocephaly in Japan. SUBJECTS AND METHODS Diagnostic and other medical information of children with macrocephaly younger than 4years (n=93) were collected for analysis. PTEN(More)
AIM To determine the use of high b value diffusion-weighted imaging (DWI) in the diagnosis and assessment of acute febrile encephalopathy/encephalitis in childhood. SUBJECTS AND METHODS We enrolled 22 children, for whom we examined DWI with b=1000s/mm2, DWI with b=3000s/mm2, and apparent diffusion coefficient (ADC) map with b=1000 during the acute phase(More)
