Study of depression and associated factors in traumatic brain injury Anand sharma, Prof. R. S. Mittal, Achal Sharma, Akhilesh jain , I.D.Gupta Depression No Depression Introduction Incidence 1,444,000 patient had TBI per year 80% are mild to moderate head injury Post TBI patients had emotional, behavioral, physical, and psychosocial problems Aim And objective To investigate the prevalence and determinants of depression and its correlation with quality of life in patients of TBI. Material and method Inclusion criteria –Patients with mild to moderate TBI those who can be able to comprehend or answer verbal or written questionnaires. Exclusion criteria- to have a serious medical illness, to have a history of current or past psychosis or mania or any other mental disorder except MDD using DSM-IV criteria Tools Used- PHQ 9 and QOL BREF WHO for assessment of depression and QOL. Discussion 1.Strong association between head injury and depression corroborating findings of other studies (Creed F et al. 1990, Anderson KO et al. 2.Severity of head injury is associated with the severity of depression. 3. Strong association has been established between duration of head injury and occurrence of depression.4.Left frontal and left temporal contusions are high risk factor for occurrence of depression. 5.Quality of life is poor in traumatic brain injury patients. 6.Coexisting depression independently affect quality of life and outcome in traumatic brain injury Conclusion Depression are commonly associated, yet under diagnosed clinical entities in head injury and have tremendous impact in overall outcome measures. Every patient of head injury warrants psychiatric evaluation and concomitant treatment if required to ensure the attainment of not only neuroanatomical intact but overall productive and qualitative life vindicating the holistic and multidisciplinary treatment approach.
