Effect of anti-depressants on neuro-behavioural consequences following impact accelerated traumatic brain injury in rats

Indian J Exp Biol. 2010 May;48(5):466-73.

Abstract

Disruption of normal neuronal networks and neurotransmitters like serotonin and norepinephrine levels in post traumatic brain injury (TBI) are observed to be the primary causative agent for depression/anxiety. This communication reports the efficacy of various classes' anti-depressants in the treatment of depression/anxiety following TBI in rats. Chronic treatment with anti-depressants (escitalopram and venlafaxine) leads to improvement in the depressive/anxiogenic-like behaviour in the TBI rat and corroborates the notion of the involvement of serotonin and norepinephrine in the behavioural consequences of post-TBI. Chronic treatments with escitalopram and venlafaxine significantly reversed the effect of TBI as compared to vehicle-treated TBI group. The results showed a quantitative battery of neuro-behavioural functional assessments that correlates with neuronal damage following traumatic brain injury.
