What is the evidence for impusivity-related disorders?

Moderate quality evidence suggests the prevalence of problem gambling in people with bipolar disorder is around 9%. This is lower than in people with nicotine dependence (56.4%), major depressive disorders (29.9%), alcohol use disorders (21.2%), anxiety disorders (17.6%), social phobia (14.9%), generalised anxiety disorder (14.4%), panic disorder (13.7%), post-traumatic stress disorder (12.3%), cannabis use disorder (11.5%), attention-deficit hyperactivity disorder (9.3%), and adjustment disorder (9.2%). Risk factors for problem gambling include suicidal ideation or attempt, history of rapid cycling, and younger age at illness onset.

Moderate to low quality evidence suggests more harmful behavioural addictions in general in people with bipolar disorder than controls.
