MRI-guided Focused Ultrasound (FUS) is an FDA-approved treatment option for certain motor symptoms of Parkinson’s Disease — particularly medication-refractory tremor and levodopa-induced dyskinesia. But what exactly does it do? And just as importantly — what does it not do?
In this episode, I break down:
• How MRI-guided Focused Ultrasound works
• What part of the brain is targeted
• Who may be an appropriate candidate
• How it compares to Deep Brain Stimulation (DBS)
• The risks, limitations, and realistic expectations
Focused ultrasound is not a cure for Parkinson’s. It does not slow disease progression. But for carefully selected patients, it can meaningfully reduce specific motor symptoms. As always, this episode is for educational purposes only and is not individual medical advice. Treatment decisions should be made with your neurologist and care team.
