The adverse effects of exposure to neurotoxic chemicals on the brain manifest themselves behaviorally as changes inmood and in cognitive function. Neuropsychological testing has emerged as a means of documenting and measuring these changes. This methodology has several advantages for use in both the clinical diagnosis of chemically induced disorders and the epidemiologic investigation of neurot...

This study examined the effect of sensory feedback (e.g., flashing lights and sound) on the imitation performance of children with autism and typical children group-matched for mental age. Participants were administered an immediate object-imitation task with six novel toys constructed for this study: three with a sensory effect that could be activated by imitating the modeled action and three ...

Carbon monoxide (CO) may be the cause of more than one-half of the fatal poisonings reported in many countries; fatal cases also are grossly under-reported or misdiagnosed by medical professionals. Therefore, the precise number of individuals who have suffered from CO intoxication is not known. The health effects associated with exposure to CO range from the more subtle cardiovascular and neuro...

BACKGROUND With the increase of motor vehicles, ambient air pollution related to traffic exhaust has become an important environmental issue in China. Because of their fast growth and development, children are more susceptible to ambient air pollution exposure. Many chemicals from traffic exhaust, such as carbon monoxide, nitrogen dioxide, and lead, have been reported to show adverse effects on...

Accumulating research documents typical rates in the range of 85% of mild traumatic brain injury (MTBI) showing prompt, complete resolution with 15% suffering from persistent neurobehavioral impairments. Studies of neurobehavioral symptoms of MTBI have not separated these two populations, resulting in either inconclusive or contradictory conclusions concerning the relationship of MTBI with resi...

BACKGROUND Cross-sectional neuroanatomical studies have reported abnormalities in schizophrenia that relate to disease variables. Longitudinal neuroimaging investigations that integrate anatomical, clinical, and neurobehavioral measures may help clarify the pathogenesis of schizophrenia. METHODS Magnetic resonance brain imaging and neurobehavioral studies were conducted at baseline and after ...

OBJECTIVE Nineteen patients with symptomatic carotid stenosis (>70%) were subjected to carotid endarterectomy in a prospective study to evaluate neurobehavioral changes before and 6 months following the operation. METHODS All patients were subjected to neurobehavioral rating scale one week before and 6 months after the operation. RESULTS There were no significant changes in the 27 items of ...
