Infantile autism is a syndrome of unknown aetiology and unknown neuro-anatomic substrate. The authors report a histological study of the brain of a well-documented 16-year-old female with autistic syndrome and severe mental retardation, using direct microscopic examination of the whole brain. The major findings are low brain weight, a thin corpus callosum(More)
Childhood autism is not usually considered as a neurological disease although frequent antecedents of ante, peri and postnatal injuries are found in its antecedents. Several symptoms of autism particularly in the early development, resemble the signs observed in frontal, temporal, striatal and brainstem dysfunctioning. These cerebral structures are(More)
This article reports the behavioral, biochemical, and electrophysiological effects of four therapeutic crossed-sequential double-blind trials with 60 autistic children: Trial A--vitamin B6 plus magnesium/magnesium; Trial B--vitamin B6 plus magnesium; Trial C--magnesium; and Trial D--vitamin B6. Therapeutic effects were controlled using behavior rating(More)
The Behavioral Summarized Evaluation scale (BSE), previously published and validated, was developed for the evaluation for the autistic behavior in developmentally disorder children. A revised version of this scale, the Revised Behavior Summarized Evaluation Scale (BSE-R) completed the 20-item BSE scale with the most relevant items extracted from a similar(More)
The influence of stimulus intensity on the N1 component of auditory evoked potentials recorded at fronto-central sites was investigated in respect to the spectral components of the EEG recorded at Cz, Fz and Oz. The study was performed on 14 healthy adult subjects. The only EEG frequency bandwidth that was strongly correlated with the N1 amplitude-intensity(More)
OBJECTIVE The authors investigated the metabolic maturation of the frontal cortex in pre-school autistic children. METHOD Regional cerebral blood flow (CBF) in five children with primary autism diagnosed according to the DSM-III-R criteria was studied longitudinally. Regional CBF in each of the autistic children was measured with single photon emission(More)
Preliminary analyses of 12 home movies taken by parents before the recognition of autistic disorders of their own child confirm the major value of this method for describing early signs: anomalies of eye contact, deficient variability of emotional expression, defect of attention and initiation of communication, motor abnormalities, etc. The possibilities of(More)
OBJECTIVE The authors investigated a possible cortical brain dysfunction associated with infantile autism. METHOD They measured regional cerebral blood flow with single photon emission computed tomography (SPECT) and xenon-133 in 21 children with primary autism (according to DSM-III-R criteria). Five cortical brain areas including frontal, temporal, and(More)
Auditory evoked potentials (AEPs) to tones (750 Hz--200 msec) ranging from 50 to 80 dB SPL were studied at Cz and Fz leads in 29 normal adults (15 males) ranging in age from 20 to 22. Peak-to-trough amplitudes were measured for the P1-N1 and the N1-P2 wave forms as well as baseline (500 msec prestimulus)-to-peak amplitudes for each component, i.e., P1, N1(More)
