Parkinson’s Disease: A Progressive Disorder
Parkinson’s disease (PD) is a slow, progressive brain condition that causes uncontrolled movement. Approximately seven to 10 million people around the world live with PD.1 Risk factors for PD include age, some environmental causes, head injury and genetics.
Causes and symptoms of Parkinson’s Disease
PD is known to affect an area of the brain called the basal ganglia. The basal ganglia regulate movement by controlling a balance of chemical and electrical signals between itself and other areas of the brain. When functioning properly, the basal ganglia make continuous adjustments to meet the needs of the body. When you have PD, the basal ganglia do not function properly.
When the basal ganglia function improperly, symptoms such as tremor can occur, making everyday activities more difficult. For example, drinking, eating and buttoning your shirt may be challenging. You may also experience increased social isolation as a result of the uncontrolled symptoms.
DBS for Parkinson’s symptoms
If you have PD and your symptoms have progressed to the point where you and your physician are discussing new therapy options, you may be considering an approved therapy called deep brain stimulation (DBS).
DBS is a therapy that helps reduce some of the symptoms of PD. A DBS device works by blocking electrical signals from reaching areas of the brain that cause motor symptoms. DBS therapy is adjustable, much like medication, and reversible, meaning it can be removed or turned off.
PD symptoms that DBS targets
The symptoms most commonly affected, or reduced, by DBS therapy include:
- Slowed movement
- Medication complications—dyskinesias and fluctuations
- Gait changes2
Proven effective for PD symptoms
Clinical studies have shown that DBS has:
- Proven to give patients good quality “on” time (the period of time when symptoms are being controlled) for most of their waking hours.3
- Shown 89% of caregivers and clinicians have rated overall patient symptom control improvement as good, very good or excellent.4
- Reduced the need for medication, providing relief from medication side effects.5
- Shown prolonged motor improvements up to 10 years.6
While DBS therapy is proven to help manage symptoms related to PD, it is important to understand that DBS is not a cure for PD. St. Jude Medical™ DBS therapy can treat some of the symptoms of PD, but does not cure the underlying condition.
DBS therapy is not for everyone, so it is important to talk with your physician about the benefits and risks. As with any surgery or therapy, DBS has risks and complications. See more about risks for DBS therapy.
