英文摘要 | Constructional impairment is not often reported in cases of corticobasal degeneration (CBD). We report a case who showed constructional impairment with clinical and neuroimaging features of CBD. The patient, a 64-year-old right-handed woman, presented with an insidious onset and slow progression of myoclonic jerks and dystonic contracture of her left hand within a year prior to this presentation. On examination, there were cortical sensory deficits and ideomotor apraxia. Magnetic resonance imaging showed an asymmetrical fronto-parietal cortical atrophy with more severity in the right parietal region. In the study of single photon emission computer tomography, regions of hypoperfusion were shown in the right parietal lobe as well as in the right basal ganglion. Although she achieved a full score for the Mini-mental State Examination and showed no impairments in simple figure copying, she presented constructional impairment in such psychometry items as Block Design, Object Assembly, and Digital-Symbol(table). In addition, she showed difficulties in global level perception of the global-local analysis and visuopraxic errors in Bender-Gestalt test. |
