Mania and Traumatic Brain Injury: Is there any association?

Mania is defined as an uncommon but debilitating psychiatric occurrence following traumatic brain injury. Traumatic brain injury is a leading cause of mortality and morbidity. 74% of people develop mania within 1 year following traumatic brain injury. 

The illness trajectory varied from a single manic episode to recurrent mood episodes. In some patients, rapid cycling is also reported. Rapid cycling refers to the presence of at least 4 mood outbreaks in the last 12 months that meet the measures for hypomanic, manic, or major depressive disorder.
