AbstractWe describe a 68‐year‐old woman who presented with falls, mild limb bradykinesia, axial rigidity, and a severe supranuclear gaze palsy, which failed to benefit from levodopa. She subsequently developed severe apraxia, progressive dysarthria, dysphagia, and a frontal cognitive impairment. Pyramidal weakness with fasciculations and widespread chronic partial denervation appeared shortly before her death from bronchopneumonia, 6 months after disease onset. A severe cerebral amyloid angiopathy diffusely involving the cerebral hemispheres and cerebellum was present at autopsy as well as a second pathological condition indicative of motor neurone disease. Cerebral amyloid angiopathy may rarely present with a progressive supranuclear palsy–like phenotype.
