Answer

Mortality associated with isolated posterior cerebral artery (PCA) stroke is low; therefore, the prognosis is generally good. Visual field deficits improve to varying degrees; however, they may be permanent and associated with morbidity. Some neuropsychological deficits may improve with time but are also associated with morbidity.

On average, patients with posterior cerebral artery (PCA) stroke sustain minimal or no chronic motor disability. These patients are usually able to adapt to their visual deficit so that many ADL tasks are manageable.

Among young stroke victims, 30-70% return to work, with the higher fraction being men and those educated beyond high school.

In a single-blind cluster, randomized, controlled trial of stroke patients in acute stroke units, there was a decreased likelihood of death or dependence by 90 days after hospital admission in patients who received a multidisciplinary intervention focusing on evidence-based management of fever, hyperglycemia, and swallowing dysfunction, despite the severity of the stroke.
