Posterior cerebral artery (PCA) strokes can be challenging
to diagnose, due to the variability in symptoms, which may be nonspecific and
inconsistent upon initial presentation.
The incidence of PCA strokes can be estimated between 5% to 10%.
Patients may present in a comatose state via ambulance or may walk to an emergency department without assistance. Patients with a PCA stroke may present with only a headache and mild visual changes such as vision loss, diplopia, inability to see half of the view, or difficulty reading perceiving colors, or recognizing familiar faces.
