Sleep problems and memory in stable bipolar disorder patients not taking psychiatric medications

Euthymic patients with bipolar disorder displayed significantly poorer sleep quality and memory function compared to healthy controls.

• Twenty-two psychotropic drug-free euthymic patients with bipolar disorder were assessed alongside 44 matched healthy controls.
• The quality of sleep was measured using the Pittsburgh Sleep Quality Index.
• Memory function was evaluated with the Wechsler Memory Scale-Revised.
• Significant correlations were found between years of education, hypnotic use, and visual memory index scores.
• Management of sleep complaints may be crucial for improving outcomes in euthymic bipolar disorder patients.
