What is it? A DBS is a surgically implanted device that sends electrical signals to brain areas responsible for body movement. It involves placing electrodes into the part of the brain that controls movement. The electrodes connect to a stimulator device, a tiny generator implanted in the chest that sends electrical impulses to the brain when switched on. The stimulator sends electrical pulses to regulate the faulty nerve signals that cause tremors, rigidity and other symptoms. It is then programmed and adjusted to give the best effect.
Benefits Using a DBS reduces a person's tremors and lessens wriggling movements in the body. Many people choose DBS surgery to reduce the amount of Parkinson's medications such as Levodopa and Sinemet. The side effects are:
Nausea
Dizziness
Headache
Involuntary movements (long term dyskinesia)
Worsening of constipation
Low blood pressure
Anorexia (loss of appetite)
Confusion and hallucinations
Behavioral problems, such as feeling an uncontrollable need to gamble, have sex or pursue hobbies
