[Slowly progressive dressing and constructional apraxia: symptomatological study, especially for dressing apraxia].
In 1982, Mesulam drew attention to a clinical picture characterized by slowly progressive aphasia without dementia, and since then, there have been many such reports. Recently, there have been 30 reports of slowly progressive apraxia. However, the nature of this apraxia is not uniform. We now report a patient with slowly progressive dressing and constructional apraxia. The patient is a 60-year-old right-handed woman with a 2-year history of a slowly progressive praxic disturbance. On admission, she was alert and aware of this difficulty. A neurological examination disclosed mild rigidity and myoclonus in her left hand. A neuropsychological assessment disclosed severe dressing apraxia, which was unlikely to be caused by dementia and moderate constructional apraxia. Her dressing apraxia was manifested in upper limbs, neck, trunk and lower limbs. However, she could express verbally the action of dressing. She also showed mild limb-kinetic apraxia, but neither ideational apraxia nor ideomotor apraxia was present. Aphasia and agnosia were also absent. On an MRI, the bilateral cerebral hemispheres were atrophic (right > left). A 99m-Tc ECD SPECT revealed decreased uptake in the right cerebral hemisphere and left frontal lobe, and an EEG showed slow waves over the right cerebral hemisphere. There have been 30 reports of slowly progressive apraxia. Most of these cases presented with slowly progressive clumsiness in one or both hands as an initial symptom, followed by constructional, ideomotor or dressing apraxia. Our patient differed from these cases in that dressing and constructional apraxia progressed slowly without any other apraxia except only mild limb-kinetic apraxia. There was a similarity between dressing apraxia of our patient and that of Marie's and Brain's original cases.
