Which of the following is a common side effect of neuroleptic medications?

Oculogyric crisis is indeed a recognized side effect of neuroleptic medications, particularly those that are first-generation antipsychotics. This condition features episodes of involuntary eye movement, where individuals may experience sustained upward eye movement. It is categorized under acute dystonic reactions that can occur shortly after the initiation or increase of neuroleptic therapy.

Neuroleptic medications block dopamine receptors in the brain, which is effective for managing psychotic symptoms, but this blockade can also lead to various movement disorders due to the disruption of normal neurotransmission pathways. Oculogyric crisis specifically involves an acute reaction to decreased dopaminergic activity, manifesting as abnormal eye movements.

While other side effects may occur with neuroleptic medications, such as insomnia and excessive sedation, they are not unique or characteristic of these drugs. Blurred vision can also be reported, but it is less specific compared to oculogyric crisis. The latter is a more definitive indicator of neuroleptic-induced movement disorders, making it the most accurate choice in this context.
