Which of the following is the least likely adverse effect of benzodiazepine withdrawal?

  1. Seizures

  2. Enhancement of cognitive abilities

  3. Intense craving

  4. Agitation

The correct answer is: Enhancement of cognitive abilities

The least likely adverse effect of benzodiazepine withdrawal is the enhancement of cognitive abilities. During withdrawal from benzodiazepines, individuals can experience a range of symptoms related to the central nervous system. These symptoms typically include heightened anxiety, agitation, intense cravings for the substance, and a risk of seizures, especially in cases of long-term use or high doses. Benzodiazepines are central nervous system depressants, and upon discontinuation, the body may struggle to recalibrate its functioning. Withdrawal can result in cognitive deficits such as memory difficulties, confusion, and impaired attention rather than improvements in cognitive abilities. Thus, the notion of enhanced cognitive function during withdrawal is contrary to the observable effects experienced during this challenging phase.
