What is a common side effect of chronic alcohol use and withdrawal?

Chronic alcohol use and subsequent withdrawal often lead to a range of neurological and psychological symptoms due to the brain's adaptation to the presence of alcohol. One significant consequence of withdrawal is the potential for hallucinations, which can manifest as visual, auditory, or tactile disturbances. This phenomenon is often associated with a condition known as alcohol withdrawal delirium or delirium tremens, which is a severe manifestation of withdrawal characterized by acute confusion, tremors, and hallucinations.

Hallucinations arise because of the brain's hyperactivity and excitability when alcohol, which has a depressant effect, is removed. This disruption in neurotransmitter balance, particularly involving gamma-aminobutyric acid (GABA) and glutamate, leads to these sensory distortions. Recognizing and managing hallucinations during alcohol withdrawal is crucial for patient safety and effective treatment, thus making it an important aspect of both chronic alcohol use and the withdrawal process.

Other options, such as cirrhosis, are long-term effects of sustained alcohol consumption rather than a direct side effect of withdrawal. Polyuria and oliguria relate to urination patterns but do not specifically correlate with the withdrawal process. Thus, hallucinations are a distinct and notable side effect of alcohol withdrawal.
