Abstract

Objective: A large and under-recognized sub-set of patients suffer both traumatic brain injury (TBI) and alcohol dependence (ADep). This group appears to use alcohol to self-treat affective and anxiety lability following TBI, resulting in new ADep or worsened prior ADep. This study hypothesized that treatment of such patients with mood-stabilizing medications would relieve post-TBI emotional dysregulation and facilitate reduction in alcohol use.

Design: This study reported retrospective medical record data from outpatients in the Substance Abuse Treatment Programme who were treated for labile mood. Medications followed clinical indication and were given in non-blind fashion.

Method: Subjects included 18 patients who (1) complained of debilitating affective lability following TBI, (2) described drinking alcohol to ease lability symptoms, (3) met DSM-IV criteria for current ADep and (4) were treated with a mood stabilizing medication.

Results: During 6 weeks of treatment, 16 (89%) achieved abstinence from alcohol. All but two (14/16 or 88%) also showed improvement in their affective and anxiety symptoms.

Conclusions: These preliminary data are limited by the retrospective collection, clinical impression and non-blinded trial. Nonetheless, the results suggest further investigation of anti-convulsants as potentially useful agents in co-morbid emotional lability and ADep following TBI.
