title: Theophylline effects on cognition, behavior, and learning.
abstract: OBJECTIVE
  To compare a group of hospitalized asthmatic children taking theophylline with a similar group of hospitalized nonasthmatic children on standardized measures of distractibility, attention, hyperactivity, and academic achievement.
  
  
  METHODS
  Standardized psychological tests were used to measure cognition, attention, and learning, and results for the two groups were compared.
  
  
  METHODS
  All subjects were hospitalized in an intermediate care facility.
  
  
  METHODS
  Up to 63 asthmatic children taking theophylline were compared with a group of 46 nonasthmatic children matched for age, sex, socioeconomic status, and full-scale IQ. Children with head injuries, mental retardation, or known learning disabilities were not included.
  
  
  METHODS
  All asthmatic children and none of the nonasthmatic children maintained therapeutic levels of theophylline during the evaluation period.
  
  
  METHODS
  Independent t tests were used to examine differences between groups on psychological tests of cognition, attention, and learning.
  
  
  RESULTS
  No significant differences were found between groups on any variables at the 95% level of confidence.
  
  
  CONCLUSIONS
  While idiosyncratic side effects of theophylline are possible, most children are not more hyperactive, distractible, short of memory, different in academic achievement, or more impulsive than other children with chronic illness.
