Ref: Kaplan Sadocks Synopsis of Psychiatry, XthCh.12.2, Page no, 397.In a alcoholic man, Blackouts occur in Alcohol intoxication.Discussion:Alcohol intoxication Behavioral changes, slowing of motor performance, and decrease in the ability to think clearly may appear with a blood alcohol level as low as 20 to 30 mgdL. Most people show significant impairment of motor and mental performance when their alcohol levels reach 100 mgdL. With blood alcohol concentration between 200 and 300 mgdL, slurred speech is more intense and memory impairment, such as blackout and anterograde amnesia, becomes common. In a nontolerant person, a blood alcohol level over 400 mgdL can produce respiratory failure, coma, and death. Due to tolerance, chronic heavy drinkers can present with fewer symptoms, even with blood alcohol levels greater than 500 mgdL.
