Transcript of By Lisa Rosenberg Deep Brain Stimulation. Electrical probe implanted in brain Approved by FDA in mid...
• Electrical probe implanted in brain
• Approved by FDA in mid 1990’s
• Hidden under skin• Does not damage healthy tissue
• Improves motor function
• For individuals who do not respond to medication
What is Deep Brain Stimulation?
• Implanted in specific areas of brain
• Differs depending upon disorder being treated
• Relieves Symptoms• Parkinson’s• Essential Tremors• Dystonia• OCD
How it Works
• Parkinson’s Disease• Globus Pallidus• Subthalamic Nucleus • Thalamus• Dystonia• Globus Pallidus• Essential Tremors• Thalamus• Obsessive Compulsive Disorder• Ventral Capsule
Illnesses Treated
• Probe is smaller than a millimeter• Four metal pads on probe
• Takes several hours
• Several scans done to map placement
• Patient is awake for surgery
• Hole drilled in skull
• Probe kept in place
with cap
Implantation of Device
• Wire planted under skin• Pulse generator planted under
collarbone• High Frequency• 100 times per second
• Implanted in both sides
of the brain• Programmed by wand
held in front of generator
Implantation of Device
• Risks associated with surgery• Intracranial Bleeds (12%)• Seizures (3%)• Headaches (25%)• Infection (6%)• Device complications• Probe replacement (9%)• Wire replacement (6%)• Repositioning of the probe (8%)• Replacement of pulse generator
(17%)• Risk of Death < 1%
Risks
• Keeps brain tissue in tact• No lesions• No destruction of the tissue
• Beneficial long term
• Costs covered by Insurance company• Around $70,000 if no insurance
• Battery lasts a long time• Replaced every 3 to 7 years with a simple
surgery
• Provides individuals with a manageable lifestyle
Benefits
• Asleep DBS• Done in a MRI machine• Possibility to treat many functional
disorders• Alzheimer’s Disease• Depression• Developing technology
