Children with Attention Deficit Hyperactivity Disorder have problems with some cognitive functions. Also, these children are more likely to drop out of school than normal children.

this study was to investigate the effect Transcranial direct-current stimulation of brain (tdcs) on cognitive ability and working memory of students with attention deficit hyperactivity disorder.

The statistical population of the present study was all students aged 15-18 years who referred to the Psychology Clinic in Tehran in 1399-1400. Among them, 32 people were selected using available sampling method and were placed completely randomly in two experimental groups (16 people) and control group (16 people). Participants in the experimental group received 18 single sessions of 30-minute transcranial stimulation of the brain using direct electric current. Cognitive and problem solving questionnaires were used to collect data. Data were analyzed using SPSS software and statistical method of analysis of variance with repeated measures.
