About

Transcranial magnetic stimulation (TMS) is a procedure that has been shown to improve fatigue in chronic sufferers. It uses a plastic covered coil that sends a magnetic pulse through the skull into the brain and by targeting particular areas in the brain it can be used to help modulate the perception of fatigue.

The study intends to use this technique to treat such a disabling symptom in patients who suffer from Multiple System Atrophy (MSA). Initially the aim is to study this technique in 22 MSA patients who are suffering from fatigue . These patients would require an resting-state funtional MRI before and after the stimulation. The stimulation would be performed ten sessions and the patients would be assessed by a clinician using well recognized clinical tools.

It is anticipated that there will be a meaningful improvement in fatigue. It is also anticipated that TMS is a safety technique to use in MSA patients . Our findings will revealed that fatigue may be associated with an altered default mode network and sensorimotor network connectivity in MSA patients. We hypothesize that these divergent motor and cognitive networks connectivity changes and their adaptive or maladaptive functional outcome may play a prominent role in the pathophysiology of fatigue in MSA.
