Timeline
Screening 3 weeks
Treatment Varies
Follow Up during the 1 week of treatment, with follow up 1 week, 3 weeks, and 2 months post-stimulation.

Summary

This trial will test whether electrical brain stimulation can help improve cognition and mood in patients with various mental disorders.

Who is the study for?
This trial is for individuals with schizophrenia, autism, bipolar disorder, Parkinson's disease, or major depression. Participants must be able to consent and not have a recent substance use disorder (except tobacco), uncontrolled high blood pressure, significant heart disease, kidney disease, seizures/epilepsy or certain other medical conditions.
What is being tested?
The study tests if cerebellar stimulation using Repetitive Transcranial Magnetic Stimulation (rTMS) can improve cognitive function and mood in patients. Some will receive real rTMS while others get a sham treatment to compare outcomes.
What are the potential side effects?
Possible side effects of rTMS include headache, scalp discomfort at the site of stimulation, tingling or spasms in facial muscles. Rarely it may cause seizures or hearing loss if ear protection isn't used.
