Self-Reported Executive Functioning in Everyday Life in Parkinson’s Disease after Three Months of Subthalamic Deep Brain Stimulation

Table 3

Comparison of the BRIEF-A general composite score (GEC), the two index scales (MI and BRI), and the nine clinical subscales (Inhibit, Shift, Emotional Control, Self-Monitor, Initiate, Working Memory, Plan/Organize, Task Monitor, and Organization of Materials), preoperatively and after 3 months of STN-DBS. Group mean -scores and standard deviations (SD) for each scale are reported along with mean differences and values. BRIEF-A validity scales are reported with mean raw scores and standard deviations (SD). Bonferroni’s adjusted values.
