[Postpolio syndrome. Neurologic and psychiatric aspects].

Postpolio syndrome is defined as a clinical syndrome of new pareses in individuals who had been affected by acute paralytic poliomyelitis years before. The objective of this study was to describe neurologic and psychiatric signs of the disease. We evaluated the clinical signs and treatment of 16 patients with postpolio syndrome. Possible symptoms of depression were evaluated by the Hamilton and Geriatric Depression Scales. Postpolio syndrome manifested at a median age of 57.5 years (range 25-73) in a median of 41 years (range 16-70 years) after acute poliomyelitis. Muscles already affected during acute poliomyelitis were affected in all patients with postpolio syndrome. Six of 16 patients (37.5%) developed paresis in muscles formerly not affected by acute poliomyelitis. In eight of 15 patients (53%), depressive episodes were recognized according to the ICD-10 criteria. Symptoms of depression should be recognized in patients with postpolio syndrome and incorporated in therapy based on physiotherapy.
