title: Manic syndrome following head injury: another form of secondary mania.
abstract: Two cases of mania secondary to head injury are reported. Only four well-documented reports of head trauma as a cause of secondary mania were found in an English and foreign literature search, although such a search is made difficult by the paucity of cases meeting modern diagnostic criteria for mania. Previous reviews of the causes of secondary mania have not included head injury, but the two case reports confirm that head injury may be an additional cause. A diagnosis of mania secondary to head trauma should be considered in manic patients with atypical age of onset, absence of previous psychiatric illness, negative family history for bipolar illness, and close temporal proximity of head trauma to subsequent mania.
