Aim of our study was to investigate the different effects on attentional capacity of deep brain stimulation DBS (STN or GPi) and of l-dopa in PD patients. Patients were evaluated on-DBS/off-l-dopa, on-l-dopa/off-DBS, on-l-dopa/on-DBS and off-l-dopa/off-DBS. Our results indicate that DBS effects on attentional functions parallel those of l-dopa. A site independent (both STN and GPi) worsening of verbal fluency was observed, possibly connected to the stimulus effect on the cortico-subcortical-cortical loop.
