Introduction and objectivesTraumatic brain injury (TBI) can result in a variety of neuropsychiatric disturbances ranging from subtle deficits to severe intellectual and emotional disturbances, including cognitive impairments, mood and psychotic disorders and behavioral disturbances. Alcohol use disorder (AUD) and TBI are closely related. The reward-mediated behaviors central to alcohol addiction seem to interact with the cognitive dysfunction of TBI. First, a significant proportion of patients with TBI have a history of alcohol abuse. Second, AUD might jeopardize TBI recovery and trigger or lower seizures threshold. Third, both AUD and TBI share a negative impact on mental functioning (from memory and cognitive performance to mood impairment). Finally, there is some limited and recent evidence that TBI can increase AUD in patients with no history of substance use prior to the injury, by disrupting incentive-motivation neurocircuitry.MethodsWe aim to present a 27-year-old Portuguese male patient without prior psychiatric history who developed AUD and epilepsy after TBI (from a work-related fall).ResultsAfter 3 years of treatment, the patient's hasn’t achieved abstinence. His treatment included pharmacological therapy with mood stabilizers, flufenazine injections and naltrexone, psychotherapy and rehabilitative interventions.ConclusionsGiven the sparse knowledge about this dual diagnosis, the approach of AUD after TBI is still challenging and the best treatment remains to be determined. Monitoring alcohol consumption should be considered in all patients presenting with TBI.Disclosure of interestThe authors have not supplied their declaration of competing interest.
