BACKGROUND: Minor traumatic brain injury accounts for about 70% of the head injuries. The major dysfunctions which goes unnoticed  are cognitive, behavioral and personality related complaints.

METHODS: A total of 166 cases of mild head injuries were included in the study. The outcome assessment was based upon the MMSE scale and tests like  trail making A,B, naming, memory–(immediate, delayed), attention, language abstraction, orientation fluency, calculation visuoperception done immediately, after one week, 3 and 6 month.

RESULTS: 79.5% of  patients were < 40 years. 81 patients had abnormal NCCT. MMSE scores were affected significantly in the group of frontal, temporal and parietal lesions both sided. Trail–A, B, abstraction, attention and arithmetic continued to show statistical difference followed by attention, memory, visuospatial and visuoperception. Least affected  were naming ,language, abstraction, orientation.

CONCLUSION: MMSE scores improved in both with abnormal and normal NCCT at 6 months but the cognitive tests showed significant impairment.
