The authors present psychiatric and neurologic data on 20 patients who developed mania after closed head trauma. An association was seen between severity of head trauma (based on length of posttraumatic amnesia), posttraumatic seizure disorder, and type of bipolar disorder. The manic episodes were characterized by irritable mood rather than euphoria and by assaultiveness. Psychosis occurred in only 15% of the sample, and 70% had no depressive episodes. Bipolar disorders were absent among 85 first-degree relatives. The authors suggest that posttraumatic seizures may be a predisposing factor in posttraumatic mania.
"These authors found a significant association between mania and the presence of post-traumatic seizures , predominantly of the partial complex type (temporal lobe epilepsy). There was no association, however, with family history of bipolar disorder among first-degree relatives (Shukla et al., 1987). We have previously reported that six out of 66 TBI patients (9%) developed manic or mixed episodes at some point during the first year following TBI. "
"Association to trauma severity, cognitive impairment and seizures was not found. However, another study related mania after TBI to seizures (Shukla et al 1987). A case report by Murai and Fujimoto (2003) described a patient who developed rapid cycling bipolar symptoms after a circumscribed lesion in the left temporal pole due to TBI. "
[Show abstract][Hide abstract] ABSTRACT: Psychiatric disorders after traumatic brain injury (TBI) are frequent. Researches in this area are important for the patients' care and they may provide hints for the comprehension of primary psychiatric disorders. Here we approach epidemiology, diagnosis, associated factors and treatment of the main psychiatric disorders after TBI. Finally, the present situation of the knowledge in this field is discussed.

[Show abstract][Hide abstract] ABSTRACT: ZET: Sol temporal bölge lezyonu ile ilişkili atipik psiki-yatrik semptomlara sahip iki olgu sunumu Genel tıbbi durumla ilişkili pek çok etmen psikiyatrik bozukluklara sebep olabilir ve beyin lezyonları da özellikle tipik olmayan belirti ve bulgular oluşturması sebebiyle önemli bir risk faktörüdür. Psikiyatrik belirtilerle beyin içi lezyonun tipi ve lokalizasyonu arasında ilişki vardır. Bu vaka sunumunda sol temporal bölgede lezyonu bulunan iki olgu dolayısıyla, belirgin nörolojik belirtiler ortaya çıkmadan görülen karışık psikiyatrik belirtiler ve bu tür olgularda tedavi yaklaşımları tartışılacaktır. Her iki olgu da hem tanı hem de tedavi açısından klinisyenin beyin lezyonuna ikin-cil olarak oluşan psikiyatrik bozuklukların ayırıcı tanısının yapılmasında dikkatli olması gerektiğini hatırlatmaktadır.

There is an association between lesion type, location, and psychiatric symptoms. Common psychiatric comorbidities of brain lesions include affective, cognitive, and behavioral disorders; therefore, organic causes should be carefully investigated by clinicians and treatment regimens planned by considering organic causes. In this report, two patients with left temporal lesions, who developed atypical psychiatric symptoms, are described and the distinctive features of their diagnoses are summarized.
