Neuropsychological functioning following craniopharyngioma removal.

The neuropsychological functioning of patients who had undergone surgical removal of craniopharyngiomas was compared to that of an endocrine control group composed of patients with nontumor hypopituitarism, an obese control group, and a normal control group. Neuropsychological assessments consisting of measures of intelligence, memory, attention, and executive functioning were carried out. The craniopharyngioma group had lower Performance IQ than did the normal control group, but their Performance IQ was comparable to that of the hypopituitarism and obese control groups. The craniopharyngioma patients did not differ in Verbal or Full Scale IQs from the remaining groups. There were no group differences on measures of verbal or nonverbal memory, ability to sustain attention, or executive functioning including measures of verbal or figural fluency, nonverbal problem solving, ability to copy a complex geometric figure, and visual motor and visual sequencing skills. The group mean scores on the measures of intelligence and neuropsychological abilities for the craniopharyngioma patients were in the low-average to average range. While craniopharyngioma patients can have significant morbidity including endocrine and visual deficits as well as obesity resulting from hyperphagia, neuropsychological deficits are not always present. Their neuropsychological outcome is more benign than some previous studies have suggested.

Risk for injury in preschoolers: relationship to attention deficit hyperactivity disorder.

Parental ratings of preschoolers' risk for injury, direct assessment of preschoolers' behavior thought related to risk for injury (e.g., Inattention, impulsivity) and number of documented injuries were examined in preschoolers with Attention Deficit Hyperactivity Disorder (ADHD) and their non-ADHD peers (Control). Of preschoolers with ADHD, 58.3% exhibited behavior which placed them at-risk for physical injury (0% Control), and their performance was significantly poorer on clinic-based tests. Nonetheless, preschoolers with ADHD did not actually sustain significantly more injuries which warranted medical treatment in an emergency department. Although preschoolers with ADHD may be at increased risk for minor injuries, further research is needed to determine whether they more frequently sustain more serious injuries.

Neuropsychological outcome in children with acquired or congenital renal disease.

The neuropsychological abilities of children with congenital ( n=13) or acquired ( n=11) end-stage renal disease (ESRD) were compared. Patients were being treated with or being prepared for dialysis and were awaiting transplantation. None of the children had an identifiable syndrome with associated central nervous system (CNS) dysfunction or had exposure to drugs with known CNS toxicity. There were no group differences in intelligence, academic achievement, behavior, or immediate memory. Children with congenital ESRD had poorer fine motor coordination and more difficulty on tests of verbal and nonverbal long-term memory than children with acquired ESRD. However, the neuropsychological outcome for congenital ESRD is more favorable than previously described. Psychological and education treatment recommendations should be considered.
