Alcohol intoxication

Overview


Plain-Language Overview

Alcohol intoxication occurs when a person consumes a large amount of alcohol in a short period, affecting the brain and nervous system. It leads to changes in behavior, coordination, and judgment, making it difficult to think clearly or control movements. The condition can cause slurred speech, impaired balance, and slowed reaction times. In severe cases, it may result in confusion, vomiting, or loss of consciousness. The effects happen because alcohol acts as a depressant on the central nervous system, slowing down brain activity.

Clinical Definition

Alcohol intoxication is an acute condition characterized by the ingestion of ethanol leading to central nervous system depression and impaired cognitive and motor functions. It results from excessive alcohol consumption that overwhelms the body's metabolic capacity, primarily involving the liver enzyme alcohol dehydrogenase. The condition manifests with behavioral changes, impaired judgment, ataxia, and slurred speech. Severe intoxication can cause respiratory depression, hypoglycemia, and coma, posing significant risks to life. Diagnosis is clinically based on history and physical examination, supported by elevated blood alcohol concentration (BAC). The condition is a major cause of trauma, accidents, and acute medical emergencies.
