JAQUELINE DE CARVALHO, Rodrigues et al. Assessment of apraxias in patients with left­sided cerebrovascular lesion. Psicol. teor. prat. [online]. 2011, vol.13, n.2, pp. 209-220. ISSN 1516-3687.

Investigations confirm the left hemisphere (LH) is dominant for motor planning. However, more studies on the participation of cortical and subcortical regions of LH in the apraxias are necessary. This multiple cases study analyzed the performance of five patients with ischemic cerebrovascular lesion in LH in three types of apraxias. The participants, aged 43‑73 years, were divided into two groups with regard to their lesion site, cortical or subcortical. Tasks of the Brief Neuropsychological Assessment Battery Neupsilin were used. Scores of each case were compared to the average performance of their normative group. Only patients with cortical lesions showed deficits of ideomotor apraxia. In the tasks of constructive apraxias, the error types distinguished the two groups. The qualitative method contributed to understand the mechanisms involved in the apraxias and to plan programs of neuropsychological rehabilitation.
