Impulse control disorders
Impulsivity may also be a manifestation of other psychiatric disorders, especially manic episodes, obsessive-compulsive disorder, borderline personality disorder, and antisocial personality disorder. There is a high comorbidity between impulse control disorders and these other disorders as well as affective disorders and substance abuse disorders.
Although impulse control disorders can occur at any time during childhood and adulthood, symptoms most commonly present during adolescence with a male predominance.
Impulse control disorders can be associated with other medical conditions. A case-control study on members of the US Armed Forces demonstrated an association of impulse control disorders with previous treatment with dopamine agonists, mental health disorders, and fibromyalgia. Likewise, a longitudinal study on patients with Parkinson disease showed a strong association between the prevalence of impulse control disorders and the use of dopamine agonists.
