Cognitive and clinical outcomes associated with cannabis use in patients with bipolar I disorder.

Figure 1

“The objective of the present study was to compare clinical and neurocognitive measures in individuals with bipolar disorder with a history of cannabis use disorder (CUD) versus those without a history of CUD…

We compared the groups on clinical and demographic variables, as well as on performance on neurocognitive tests…

CUD+ subjects demonstrated significantly better performance on measures of attention, processing speed, and working memory…

Interestingly, bipolar patients with history of CUD had better neurocognitive performance as compared to patients with no history of CUD.

…these analyses indicate an interesting pattern suggesting superior neurocognitive performance among bipolar patients with comorbid CUD when compared to bipolar patients with no history of cannabis use.”
