Deep Brain Stimulation: Treating Parkinson’s, Dystonia, Depression and More

Imagine a one-size-fits-all solution to neurological conditions. Dr. Andres Lozano of the University of Toronto may have discovered the closest technology we have to an-purpose solution for patients who suffer from a number of neurological disorders. The project is known as Deep Brain Stimulation and involves the implanting for electrodes in a patient’s brain. The electrodes are then used to stimulate specific neurons in the brain with a small, electrical charge. The electrodes then work by either suppressing or stimulating the activity of neurons. So far, this technology has been successful in treating patients with Parkinson’s, dystonia and severe depression. Clinical trials are beginning to see the effects of Deep Brain Stimulation on Alzheimer’s patients. So far the technology has been shown to improve glucose use in the brain, potentially increasing brain activity in regions of the brain which have been “turned off.”
