Experts believe the right dose of alcohol, however, stops the cascade of swelling, inflammation and further destruction of brain cells, known as secondary brain injury.

The latest work, based on more than 38,000 moderate-to-severe head trauma patients, is the largest yet to look at the effects of alcohol on brain injury survival.
Like past research, Dr Ali Salim and his colleagues from the Cedars-Sinai Medical Center, in Los Angeles, found head injury patients who had drunk were significantly less likely to die than those who had not had any alcohol.
They also tended to be younger and have less severe injuries.

Some medical opinions
Dr John Heyworth, president of the College of Emergency Medicine, said: "This is a long way from thinking about giving alcohol to patients in A&E. But if, in the future, the science and evidence proves that it would be beneficial, we would consider it."
Professor Michael Oddy, of the Brain Injury Rehabilitation Trust, said: "Despite the intriguing findings the message must be the same - if you wish to avoid a brain injury, use alcohol with care and moderation."
Alcohol Concern chief executive Don Shenker said: "The fact is, being drunk increases your chances of getting into an accident in the first place. When judgement's impaired, we can put ourselves at risk."
