Abstract

Background: Epileptic seizures have destructive effects on the brain, because they intervene in healthy and normal brain processes, and create interference at different stages of memory and cause malfunction in its performance and function, especially in the early years of life. The purpose of this study was to investigate memory as one of the important areas of cognition in patients with epilepsy.

Methods: In this causal-comparative study, the subjects consisted of 52 children of 8 to 14 years of age with epilepsy. Among them, 15, 16, and 15 patients had parietal lobe epilepsy, temporal lobe epilepsy, and frontal lobe epilepsy, respectively. The participants were selected among the patients referring to the clinic of a neurologist. Rey-Osterrieth complex figure (ROCF) test was used to assess visual memory.

Results: The visual memory scores in the epilepsy group were lower than the healthy group and the difference between the two groups was significant (t = 33.76, df = 103, P < 0.001). No significant difference was obtained between the three epilepsy groups in terms of visual memory scores (f = 1.6, df = 2, P < 0.212). In the present research, no significant difference was observed in visual memory between the three epilepsy groups.

Conclusion: It can be concluded that patients with epilepsy have impaired visual memory.
