Pharmacotherapy to prevent the onset of depression following traumatic brain injury

Introduction: Depressive symptoms may follow traumatic brain injury (TBI), affecting cognition, apathy, and overall general functioning. Pharmacotherapy to prevent the onset of depression following TBI is, therefore, crucial. Areas covered: The present report critically appraises current pharmacotherapy to prevent the onset of depression following TBI as well as novel potential pharmacological avenues on the matter. Both efficacy and safety issues are considered, emphasizing an evidence-based approach whenever feasible. The authors further provide the reader with their expert opinion and future perspectives on the subject. Expert opinion: Despite its clinical burden and relatively frequent occurrence, the prophylaxis of post-TBI depression warrants further research. The current clinical guidelines of depression do not account for people with a primary diagnosis of TBI. Prospective cohort studies supported by proof-of-concept trials are nonetheless urged toward more effective, patient-tailored pharmacotherapy to prevent the onset of depression and treatment-resistance phenomena following TBI.
