Which of the following symptoms is linked to the withdrawal process of benzodiazepines?

The withdrawal process from benzodiazepines is often characterized by a range of symptoms due to the body's adjustment to the absence of the drug. Severe irritability is a common symptom associated with benzodiazepine withdrawal. As these medications are central nervous system depressants, stopping them suddenly can lead to increased levels of anxiety, agitation, and irritability as the body reacts to the change in chemical balance.

During withdrawal, individuals may experience heightened emotional responses, and irritability is particularly common because benzodiazepines often suppress anxiety and mood fluctuations when they are in the system. Once the drug is removed, these effects can manifest as irritability and mood swings that may be intense.

The other options—such as increased alertness, rapid weight gain, and enhanced cognitive function—do not accurately reflect the withdrawal experience of benzodiazepines. In fact, withdrawal is more likely to lead to decreased cognitive function and other cognitive challenges due to the body's need to recalibrate after cessation of the drug. Thus, the identification of severe irritability as a symptom of benzodiazepine withdrawal is well-supported by the available literature on substance withdrawal.
