Abstract:   (837 Views)
Objective: Previous studies on ADHD indicate impairments in executive functions including working memory. In addition, there are findings pointing to impairments in visual memory in these children. The objective of this study was to assess visual memory in children with ADHD using neuropsychological tests sensitive to temporal lobe function.
Method: In this cross-sectional analytical study, forty one 6-12 year old children with ADHD and normal IQ with no history of drug treatment were compared to 30 normal children matched for sex, age and IQ, using the neuropsychological tests Paired Associated Learning (PAL), Delayed Match to Sample (DMS) and Pattern Recognition Memory (PRM).
Results: ADHD children showed poorer performance on PAL than the normal group; significantly higher total errors and tries and significantly lower completed stages was. In DMS the percentage of correct responses in the patient group was significantly lower than the control group and this difference was also significant regarding the percentage of correct responses, total delays, and simultaneous display. The results in PRM test showed that the percentage of correct responses and the delay to correct response was worse in the patient group than in the normal group. However, this difference was not significant.
Conclusion: The performance of non-treated ADHD patients in tests sensitive to temporal function in general and visual memory in particular shows some impairment in comparison with the control group.
