Alcohol withdrawal and delirium tremens

What it is

Delirium tremens is an acute and sometimes fatal reaction to alcohol withdrawal. It starts within 48-96 hours after cessation of a heavy drinking pattern, so it is not the first thing to appear once drinking stops but the last stage of a course that gets worse over days.

How it presents

Alcohol withdrawal runs through stages, and each stage adds to the one before it.

Put another way, withdrawal symptoms include tremors, anxiety, hypertension, tachycardia, sweating and insomnia; the more severe withdrawal symptoms are tonic clonic seizure, visual hallucination and delirium tremens. Visual hallucination is a sign of alcohol withdrawal.

The characteristic symptoms of delirium tremens itself are confusion, tremor, delusions, hallucinations and autonomic hyperactivity.

Two described cases show the shape of it. A man of 35 presented with severe insomnia and tremulousness, mostly in the morning, associated with paranoid delusion, confusion and visual hallucination. A male of 65 presented with tremor, difficulty sleeping, nausea, agitation and transient visual hallucinations 3 days after he stopped drinking alcohol following a 3-day heavy spell, with increasing confusion over the past several hours.
