Brief summary

We assessed Montreal Cognitive Assessment scores before and after MRI guided focused ultrasound thalamotomy for tremor in order to identify if there are changes in cognitive function following treatment.

Detailed description

All patients who underwent MRI guided focused ultrasound thalamotomy underwent cognitive assessment by Montreal Cognitive Assessment. We calculated the scores before and after treatment and compared the results.
