What symptoms may occur during withdrawal from alcohol?

Withdrawal from alcohol can lead to a range of symptoms due to the body's physical dependence on the substance. The correct answer highlights severe withdrawal symptoms that are associated with alcohol dependence, such as vivid hallucinations and disorientation. This condition is part of a more serious withdrawal syndrome known as delirium tremens (DTs), which can occur in heavy drinkers and is characterized by confusion, hallucinations, and severe agitation. Such symptoms indicate a significant disruption in neurotransmitter activity in the brain as it adjusts to the absence of alcohol.

The choice that describes mild headaches and fatigue does not capture the intensity and potential severity of alcohol withdrawal; while it's possible for some people to experience these less severe symptoms, they are not the hallmark features of withdrawal. Similarly, intense euphoria and energy are contradictory to the withdrawal experience, as the body is actually rebounding from depression due to alcohol. Hyperactivity and severe anxiety are present but do not sufficiently encompass the vivid and severe nature of hallucinations and disorientation that can occur during withdrawal from alcohol. Thus, the severe symptoms outlining vivid hallucinations and disorientation effectively represent the serious risks associated with alcohol withdrawal.
