PURPOSE Lateralization of language function is crucial to the planning of surgery in children with frontal or temporal lobe lesions. We examined the utility of functional magnetic resonance imaging (fMRI) as a determinant of lateralization of expressive language in children with cerebral lesions. METHODS fMRI language lateralization was attempted in 35(More)
Photophobia, or intolerance of light, is not completely understood as a symptom. It has been divided into ocular and central types. This study shows that persistent, usually mild, photophobia occurs in about one-third of children with cortical visual impairment (CVI). When the CVI is congenital the photophobia is present from birth, and when it is acquired(More)
The cognitive deficits associated with schizophrenia commonly include impairment in attention, which may contribute to difficulties with learning, memory, and executive function. This study evaluated the effectiveness of computer-aided training of attentional skills in schizophrenia. Two groups of schizophrenic subjects (9 men and 1 woman) were matched for(More)
Eight-year-old twins, one with a left frontal tumor and aphasic seizures, the other neurologically normal, underwent serial assessment of expressive language with functional magnetic resonance imaging and neuropsychology. The affected twin showed a significant amount of right hemisphere activation coincident with behavioral deterioration in expressive(More)
Attentional impairments in children occur in the context of both developmental and acquired disorders involving the central nervous system (CNS) and may have implications for ongoing development, potentially impeding cognitive, educational, and behavioral functions. Using a continuous performance paradigm (CPT), this study compared attentional profiles of(More)
Reports have suggested that isoniazid treatment may be associated with poor concentration and subtle reduction in memory. This study examines attentional function and processing speed in a group of 25 adolescents who received isoniazid prophylaxis for at least 6 months. As adolescents often face major educational assessment milestones, such cognitive side(More)
The authors studied 12 patients with major abnormalities of the afferent visual system following closed injury to the head. The anatomic sites of injury were the eye in five patients, the optic nerve in seven patients, the chiasm in four patients and the optic radiations in four patients. A technique for rapid evaluation of the afferent visual system in(More)
