Alcohol intoxicação is a clinically significant transient condition that develops during or shortly after the consumption of alcohol that is characterised by disturbances in consciousness, cognition, perception, affect, behaviour, or coordination. These disturbances are caused by the known pharmacological effects of alcohol and their intensity is closely related to the amount of alcohol consumed. They are time-limited and abate as alcohol is cleared from the body. Presenting features may include impaired attention, inappropriate or aggressive behaviour, lability of mood and emotions, impaired judgment, poor coordination, unsteady gait, fine nystagmus and slurred speech. At more grave levels of intoxicação, stupor or coma may occur. Alcohol intoxicação may facilitate suicidal ideation or behaviour.
