Summary: Postpoliomyelitis syndrome (PPS) is an increasingly recognized phenomenon characterized by late-onset weakness, pain, and fatigue. Psychiatric and cognitive disturbances have been noted in postpoliomyelitis patients, but the relationship of these symptoms to PPS is unknown. We examined postpoliomyelitis patients with and without PPS using objective neuropsychological and neuropsychiatric procedures. Our results suggest that disturbances of mood were common and that subtle cognitive deficits also occurred in postpoliomyelitis patients. However, patients with PPS did not have greater depression or cognitive deficits compared to postpoliomyelitis patients without PPS.
