Treatment of progressive supranuclear palsy with methysergide. A clinical study

We present a clinical study of a patient aged 69 years with a clinical history of severe difficulty in walking and voluntary conjugate eye movement reduction in sideways glance and absence in vertical gaze. These symptoms led to diagnosis of Parkinson disease and treatment with L-Dopa + anticholinergics drugs. The treatment with antiparkinsonian drugs was suspended and no change in his clinical condition resulted. Methysergide therapy was initiated and the patient's response was monitored by video recording. On the basis of our experience and the data reported in the literature we believe that methysergide therapy affords some relief of symptoms in patients suffering from PSP.
