Having low levels of alcohol in the blood may protect the brain from the effects of a head injury, a study suggests.
The University of Toronto found head injury patients who had drunk low amounts were 24% less likely to die than those who had not had any alcohol.
Heavy drinking increased the risk of death substantially – those with high levels of alcohol in their blood were 73% more likely to die than those with no alcohol.
The researchers said alcohol might one day be used as part of emergency treatment for some head injury patients.
