Post-trauma administration of caffeine plus ethanol reduces contusion volume and improves working memory in rats.

It has been demonstrated that ethanol exerts dose-dependent effects, both beneficial and detrimental, on the outcome of traumatic brain injury (TBI). Recently, it has been reported that co-administration of caffeine (10 mg/kg) and a low amount of alcohol (0.65 g/kg; caffeinol) reduces cortical infarct volume up to 80%, and improves motor coordination, following a rodent model of reversible common carotid/middle cerebral artery occlusion.
