Sleep promotes consolidation of emotional memory in healthy children but not in children with attention-deficit hyperactivity disorder.

Fronto-limbic brain activity during sleep is believed to support the consolidation of emotional memories in healthy adults. Attention deficit-hyperactivity disorder (ADHD) is accompanied by emotional deficits coincidently caused by dysfunctional interplay of fronto-limbic circuits. This study aimed...
