[Progressive loss of speech output with festinating speech--a case report].
Primary progressive aphasia is a rare disorder of unknown cause. We report a patient with progressive loss of speech output, a clinical variant of PPA, characterized by festinating speech. A 60-year-old right handed woman was admitted to our hospital, because of progressive deterioration of her speech. On admission, she was alert and orientated without dementia. A severe impairment of her articulation was observed: her speech rate was so fast that her speech became almost intelligible. The orofacial apraxia and difficulty in tapping were also present. The other neurological findings were normal. Neuroradiological studies showed the left perisylvian atrophy. Festinating speech has not been previously reported in patients with PPA; patient with PPA usually show a slow speech rate with effortful expression. Since festinating speech is occasionally present in the extrapyramidal disorders, such as Parkinson's disease, progressive supranuclear palsy, or pure akinesia, it appears likely that the combined lesions of the perisylvian region and the basal ganglia are responsible for her characteristic speech disorder with festinating speech.
