Alcohol: Intoxication

Alcohol intoxication can affect judgment, coordination, attention and emotional regulation. The degree depends on exposure and individual factors, including other substances or medicines. Behaviour during intoxication may be difficult to distinguish from psychiatric deterioration, while pre-existing symptoms can also become harder to manage.

Alcohol affects the brain, sleep, physical health and behaviour, and can interact with psychiatric treatment. Its relevance depends on the amount, pattern, timing and individual circumstances. A person with schizophrenia may use alcohol for many reasons, so assessment should be specific and non-judgmental rather than assume that any use has one explanation or effect.

Assessment considers what was consumed, when and in combination with what else. Sedating medication can increase impairment. An apparent alcohol explanation should not prevent investigation of injury, medical illness or other causes of altered awareness. Severe reduced consciousness or physical deterioration requires urgent medical care. The person’s longer-term pattern of use matters after the immediate effects settle. Understanding the episode can guide future support without treating intoxication as a complete account of every difficulty or assuming that the person deserves less respectful care because alcohol was involved.

Intoxication and psychosis can overlap in outward appearance, making direct assessment important. Coordination, consciousness, vital signs and the history of exposure provide different kinds of information. A familiar psychiatric diagnosis should not obscure injury or another medical cause. Respectful care includes investigating the current presentation rather than assuming that alcohol or mental illness explains every new symptom without examination.
