Medical Conditions That Can Make a Person Act Drunk

There are medical conditions that exist that can make a person act drunk or intoxicated.

DUI or Medical Condition?

You can’t always assume based on behavior alone that a person has been drinking or has been using drugs. If they display certain abnormal behaviors it could indicate a serious medical condition. If the situation allows you can always try and talk to the person to learn more about their condition or communicate with a relative if one is available. You might also look to see if they are wearing a medical alert bracelet that might indicate their condition.
