What effect does akathisia have on a patient?

Akathisia is a movement disorder characterized by an intense feeling of inner restlessness and an uncontrollable need to be in constant motion. Patients experiencing akathisia often find it difficult to stay still, which can manifest as pacing, foot tapping, or an inability to sit comfortably. This feeling of restlessness is usually accompanied by anxiety and discomfort, making it challenging for individuals to relax or engage in tasks that require sustained attention.

The other options do not accurately reflect the experience of individuals with akathisia. Enhancing motivation or causing overwhelming focus does not align with the disruptive and uncomfortable sensations that akathisia induces. Similarly, while cognitive function could be affected by the distress tied to akathisia, the primary impact of the condition is the persistent feeling of restlessness rather than a direct reduction in cognitive abilities. Thus, the most accurate description of the effect of akathisia on a patient is the sensation of inner restlessness.
