Neuropsychological assessment protocol in an ongoing randomized controlled trial on posterior subthalamic area vs. ventral intermediate nucleus deep brain stimulation for essential tremor.

Objective: Patients with essential tremor (ET) may experience cognitive-affective impairment. Deep brain stimulation (DBS) of different targets, such as the ventral intermediate nucleus (VIM) of the thalamus or the posterior subthalamic area (PSA), has been shown to be beneficial for refractory ET. However, there is little evidence regarding the possible neuropsychological effects of PSA-DBS on patients with ET, and there are few studies comparing it with VIM-DBS in this population.

Balance Ability and Occupational Performance in Patients With Parkinson's Disease and On-Medication-State Freezing of Gait.

Purpose: The aim of this study was to examine balance ability and occupational performance in patients with Parkinson's disease (PD) and on-medication-state freezing of gait (FOG).

Design: A cohort study with three groups was conducted.

Methods: Seven patients with PD and on-medication-state FOG with optimized pharmacological therapy; seven patients with PD matched by age, gender, length of time since diagnosis, and Hoehn and Yahr stage; and seven controls were included.
