A research team from Cedars-Sinai Medical Center, Los Angeles, studied 38,000 head trauma patients and found that head trauma patients who had drunk alcohol before suffering head injuries seemed less likely to die. They suspect that given the right dose, alcohol stop secondary brain injury (cascade of swelling, inflammation and further destruction of brain cells.
The amount of alcohol consumed seemed important with too little having no effect and too much causing the loss of the beneficial effect, based on animal studies.
Please note that those findings do not imply that one should drink alcohol before driving as alcohol affects reaction time and increases chance of accident. Also, patients with significant levels of alcohol in the blood tend to have medical complications.
The study does suggest the possibility of administering alcohol to brain trauma patients but before that become reality, more researchs need to be done.
