PSYCH-230 Chapter Notes - Chapter 1: Deep Brain Stimulation, Transcranial Magnetic Stimulation, Traumatic Brain Injury
Document Summary
Deep brain stimulation and repetitive transcranial magnetic stimulation. Deep brain stimulation: procedure used to treat various chronic mental health and health conditions that involves planting battery-operated electrodes in the brain that deliver low- level electrical impulses. Based on the observation that the subgenual cingulate region is metabolically overactive in treatment-resistant depression. Safe and effective in treating unipolar and bipolar depression. Also effective for ocd, substance abuse, traumatic brain injury, and alzheimer"s type dementia. Cost of device implantation can run as high as 250,000 per person (includes cost of the doctors) Non-invasive method of brains stimulation using brief magnetic pulses to stimulate the brain. Produces an electric current in the underlying cortex. Studies suggest it elicits a therapeutic response ind depressed people and people with chronic pain and that it may be as effective as ect. Elevations in glutamate levels were found in adolescents with depression who were successfully treated with rtms.
