Qualitative Evaluation of the Immediate Copy of the Rey-Osterrieth Complex Figure : Comparison Between Vascular and Degenerative MCI Patients

The immediate copy of the Rey-Osterrieth Complex Figure (ROCF) is considered a visuo-spatial test. However, reproducing this complex structure possibly involves also executive functions, such as planning and organizational strategies. In a previous study, we found a high rate of impaired performances in this test in a sample of subcortical vascular mild cognitive impairment patients. Executive functions contribution in the immediate copy of the ROCF can be assessed with the Boston Qualitative Scoring System (BQSS). We aimed at examining whether BQSS executive scores of ROCF immediate copy: (1) differ between vascular (v-MCI) and degenerative MCI (d-MCI) patients; (2) can at least partly explain the high rate of abnormal ROCF immediate copy performances in v-MCI patients.
