Aim: To analyse psychiatric morbidity in traumatic brain injury patients. Material and methods: This study cross sectional was done in out-patient department of psychiatry in a tertiary care institute among 152 subjects aged 15-60 years with TBI. General, detailed physical and mental assessment of traumatic brain injury patients was assessed. Scales used were M.I.N.I. 7.0 and MMSE to assess psychiatric morbidity and severity of traumatic brain injury. Results: 80 patients (52.6%) had mild injury and 72 patients (47.4%) had moderate injury. 89 subjects (58.6%) had blunt type trauma whereas 63 (41.4%) subjects had penetrating type injury. When MINI diagnosis was correlated with severity of injury, and a statistically significant correlation was found (p value 0.027). Of the total 80 patients with mild injury 42 (52.5%) subjects had Psychiatric Morbidity Absent and 38 (47.5%) subjects had Psychiatric Morbidity Present. Of the total 72 patients with moderate injury 29 (40.3%) subjects had Psychiatric Morbidity Absent and 43 (59.7%) subjects had Psychiatric Morbidity Present. Conclusion: In the treatment of head injury, apart from the treatment of physical symptoms, it is also important to treat psychiatric symptoms because psychiatric comorbidity delays the social and functional outcome of the patient. Most of it had been missed by clinicians and it affects the prognosis of the patient, so it is essential to identify the risk factors, understanding the clinical features for better treatment of the patient.
