A 63-year-old man was admitted to the hospital with a 1,5-year history of progressive dementia, supranuclear ophthalmoplegia, pseudobulbar palsy, rigidity and dystonia in the neck and the upper trunk. Magnetic resonance imagings showed severe atrophy of the frontal lobe and the brainstem. He was diagnosed as having progressive supranuclear palsy (PSP). Rigidity, nuchal dystonia, frequent micturition, and profuse sweating ameliorated after trazodone administration. Furthermore, additional administration of L-dopa and droxidopa improved his pseudobulbar palsy, akinesia, and lack of initiative. Single photon emission tomography using IMP after medication showed increased IMP-uptake in the frontal areas and the basal ganglia compared with that before medication. This patient illustrates a substantial role of impairments in the serotonin system in the production of some PSP symptoms.

Respiratory and sleep disturbances may be important causes of morbidity in Steele-Richardson-Olszewski syndrome but the frequency and character of nocturnal abnormalities remains uncertain. A prospective study of 11 patients with Steele-Richardson-Olszewski syndrome and age-matched control subjects was undertaken using clinical assessments, a structured sleep questionnaire, spirometry, static maximum inspiratory and expiratory pressures and nocturnal oximetry. The mean age of the Steele-Richardson-Olszewski syndrome patients was 63.2 (52-70) years and mean disease duration was 4.0 (2-6) years. There was moderate to severe motor disability in nine and mild to moderate dementia in eight. In the patients with Steele-Richardson-Olszewski syndrome the following abnormalities contributed to sleep disturbances significantly more frequently than in normal controls: depression, dysphagia, frequent nocturnal awakenings (usually associated with urinary frequency), immobility in bed, difficulty with transfers, impaired dressing and feeding. There was profound impairment of voluntary respiratory control whilst automatic and limbic control were well maintained. Nocturnal respiratory abnormalities were not present even in the most severely disabled. In Steele-Richardson-Olszewski syndrome sleep abnormalities are common; they relate to the cognitive, pseudobulbar and extrapyramidal disturbances and may therefore be amenable to symptomatic control.
