Abstract
Expression of cognitive and functional disorders is a common clinical development of traumatic brain injury (TBI) that is essentially determined by the site and severity of the insult. The present study sought to examine the effects of closed-head TBI on memory in albino rats, in order to further examine the potential efficacy of an acute antioxidants treatment with Dimethyl Sulfoxide (DMSO), Vitamin C and Alpha lipoic acid (ALA). The rat model of closed-head injury by weight drop method was applied on anesthetized rats. The treatment protocol included single oral administration of DMSO, Vitamin C and ALA in three different doses (22.5, 45 and 67.5 mg/kg) 1hr post-TBI. The Novel Object Recognition Test as well as the Modified Neurological severity score (mNSS) were employed to assess post-TBI memory and neurological function respectively. Our results revealed a recognition memory deficit that was significant 7 days after TBI up to 14 days post-TBI. Most importantly, DMSO, Vitamin C and ALA were able to attenuate the memory impairment by TBI. The mNSS of the treated groups decreased significantly than the non-treated group in the first and second week. Conclusively, the use of antioxidants can help in the management of TBI by reducing oxidative stress and improving cognitive function.

Key words: Traumatic Brain Injury, Impairment, Memory, Neurological severity score
