Definition:
Alcohol poisoning or alcohol overdose occurs when there is so much alcohol in the bloodstream that areas of the brain controlling basic life-support functions - such as breathing, heart rate, and temperature control - begin to shut down.
Symptoms of alcohol overdose include mental confusion, difficulty remaining conscious, vomiting, seizure, trouble breathing, slow heart rate, clammy skin, dulled responses such as no gag reflex (which prevents choking), and extremely low body temperature. Alcohol overdose can lead to permanent brain damage or death.
