Progressive supranuclear palsy with lower motor neuron involvement. A case report.

ABSTRACT

The clinical picture of progressive supranuclear palsy is relatively constant, including supranuclear ophthalmoplegia, pseudobulbar palsy, axial dystonia in extension, parkinsonian signs, postural instability and dementia. A case is reported, which is unusual in having flexor dystonia of the neck and marked signs of lower motor neuron involvement.
