Focused Ultrasound Thalamotomy for Tremor Relief in Atypical Parkinsonism

The goal of this retrospective observational study is to describe the efficacy of focused ultrasound ventral-intermediate nucleus thalamotomy in patients with atypical parkinsonism.

• Is this treatment efficacious in patients with multiple system atrophy?
• Is this treatment efficacious in patients with diffuse Lewy Body Dementia? Data will be collected from patients charts.

Inclusion Patients that underwent FUS ventral-intermediate nucleus thalamotomy Suffer from multiple system atrophy-Parkinsonian type (MSA-P) or dementia with Lewy bodies (DLBD).
