[A case of progressive supranuclear palsy showing improvement of rigidity, nuchal dystonia and autonomic failure with trazodone].
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.
