MRgFUS for Essential Tremor

Background:

MRgFUS (or HIFU) has been approved by Heath Canada for the treatment of Essential Tremor.

Purpose:

This research study is not to determine if MRgFUS is effective in the treatment of ET. Instead the purpose of the trial is to:

1) Monitor the long term outcomes of patients undergoing HIFU thalamotomy

2) Develop low intensity ultrasonic brain mapping tools

3) Develop better brain imaging protocols

 

MRgFUS for OCD

Background:

Anterior capsulotomy is an effective treatment for refractory OCD and has been in use since the 1960s. MRgFUS may be a safer way to perform this procedure.

Purpose:

While we are participating in a multicentre phase 1 trial about the safety and initial effectiveness of MRgFUS in patients with OCD, our aims are to:

1) Monitor the long term clinical outcomes of patients undergoing HIFU capsulotomy

2) Develop better brain imaging protocols

3) Develop low intensity ultrasonic brain mapping tools

Dr Sam Pichardo's Lab: (https://www.neurofus.ca)

Focus areas include: 

  • The exploration of Focused Ultrasound (FUS) as a noninvasive method for the characterization of neurological functions and the treatment of brain disorders
  • A better understanding of brain processes and cognitive mechanisms to the development of new therapies for depression, obsessive-compulsive disorders, addictions, and more, the stakes of a noninvasive, high-resolution and controlled method to induce neurostimulation are quite significant.  
  • Exploring further the mechanism and assocation between how FUS can transiently induce neurostimulation effects on the brain
  • Explore the potential applications of noninvasive neurostimulation with FUs in areas psychology, psychiatry, functional imaging and more
