اثر چرت زدن در طول روز بر روی حافظه رویه ای و اعلانی در بیماران مبتلا به اسکیزوفرنی

The present study is the first to demonstrate significant differences between individuals with schizophrenia, depression and healthy matched controls with regard to measures of sleep and memory performance after a short period of daytime sleep (napping). In particular we found that a daytime nap of only about 40 min led to improvement of declarative memory performance in all investigated groups, whereas no beneficial effect was seen on procedural performance in the group of medicated patients with schizophrenia in contrast to healthy controls and patients with remitted to moderate major depression.
