Gestural buffer impairment in early onset Corticobasal Degeneration: a single-case study
We investigated limb apraxia in a case of a clinically diagnosed Corticobasal Degeneration with early onset (48 years) in a right handed woman. We used a new battery for the assessment of limb apraxia, based on a cognitive model of praxis. This cognitive model predicts five clinical pictures of limb...
