What is Parkinson’s Disease (PD)?
Parkinson's disease is a neurodegenerative (the gradual loss of structure or function of neurons (nerve cells) in the brain or peripheral nervous system) disorder that impairs mobility.
It develops gradually and is characterized by:
- tremors
- stiffness
- delayed mobility
- poor balance
These symptoms are the result of a reduction in dopamine-producing neurons in the brain. The specific reason is unknown, but genetic and environmental factors are thought to have a role.
What is Deep Brain Stimulation (DBS)?
Deep Brain Stimulation (DBS) is a surgical procedure for Parkinson's disease. Electrodes are implanted into specific parts of the brain that control movement. These electrodes use electrical impulses to regulate aberrant brain activity, thereby alleviating Parkinson's symptoms such as tremors and stiffness. DBS can not cure Parkinson's disease, although it can greatly enhance the quality of life in some individuals.
The history of Deep Brain Stimulation (DBS) for PD (Parkinson's disease) dates back to the late 20th century. Pioneering research in the 1980s and 1990s established its effectiveness in treating motor symptoms. The FDA approved it in 2002, paving the way for widespread clinical use. Ongoing research aims to improve its effectiveness while minimizing negative effects.
Criteria for Undergoing Deep Brain Stimulation Surgery
To determine who is a potential candidate for Deep Brain Stimulation (DBS) surgery, a thorough evaluation will be conducted by a multidisciplinary team of healthcare professionals, including:
- neurologists
- neurosurgeons
- movement disorder specialists
Here are the detailed criteria for having DBS surgery:
The Diagnosis of Parkinson's Disease:
The patient must have a verified diagnosis of idiopathic Parkinson's disease, which is usually determined by clinical symptoms and drug response.

Presence of Motor Symptoms:
Candidates for DBS surgery typically have motor symptoms that have a considerable impact on their daily functioning, despite good medication management.
- Tremors
- rigidity
- bradykinesia (slow movement)
- motor fluctuations (fluctuations between mobility and immobility), such as "on-off" occurrences or dyskinesias (involuntary motions)
These are all common motor complaints.
Response to Levodopa Therapy:
The patient's symptoms should respond positively to levodopa (the principal treatment for Parkinson's disease), but there may be changes in responsiveness or medication-related adverse effects over time.
Medication Optimization:
DBS is often used when medicine alone does not properly manage motor symptoms, despite changes in:
- medication type
- dosage
- timing
Absence of cognitive impairment:
Candidates for DBS surgery should have a normal cognitive function and no severe cognitive impairment, as determined by neuropsychological tests.
Mild cognitive impairment may be tolerable in some circumstances, but severe dementia is typically regarded as a contraindication for surgery.
Absence of Severe Psychiatric Conditions:
Candidates should not have serious psychiatric disorders that would impair their ability to participate in the surgical examination, follow-up care, or adhere to post-operative management.
General Health Status:
Candidates should be in good general health and free of any serious medical issues that would put them at risk during surgery or anesthesia.
Candidates should have a complete medical examination, which includes an assessment of cardiovascular health and potential risk factors for surgical complications.
Realistic Expectations:
Candidates and their caregivers should be realistic about the potential benefits and drawbacks of DBS surgery.
They should understand that DBS is not a cure for Parkinson's disease, although it can help with motor symptoms and quality of life.
Willingness to Undergo Surgery:
Candidates must be willing to have a surgical operation and actively participate in:
- pre-operative examinations
- surgery planning
- post-operative care
Surgical Procedure for Deep Brain Stimulation (DBS) in Parkinson's Disease (PD)
The Deep Brain Stimulation (DBS) surgical technique consists of multiple steps and is carried out in a hospital by a skilled surgical team. Below is a thorough overview of the DBS surgical procedure:

Preoperative Evaluation:
Before surgery, the patient has a thorough pre-operative evaluation that includes:
- neurological tests
- imaging studies (such as MRI or CT scans)
- medical clearance
These evaluations are to confirm they are eligible candidates for DBS surgery.
Placement of Stereotactic Frame:
On the day of surgery, the patient is placed on the operating table and a stereotactic frame is affixed to the head under local anesthesia.
The stereotactic frame is used as a reference point for precise targeting of brain regions during the treatment.
Brain Imaging and Targeting:
High-resolution brain imaging, such as MRI or CT scans, is used to determine the exact brain areas that will be targeted for electrode implantation.
The neurosurgeon uses imaging data and sophisticated computer guidance tools to accurately identify the best trajectory for electrode placement.
Burr Hole and Dura Opening:
A small incision is created on the scalp, and a burr hole is drilled into the skull at the desired place.
The neurosurgeon delicately opens the dura mater (the brain's protective membrane) to gain access to the brain tissue.
Electrode Placement:
A thin, insulated electrode is placed through the burr hole and guided into the target brain region using real-time imaging and electrophysiological monitoring.
Microelectrode recording and macro stimulation are used to confirm the electrode's accurate location and determine its functional effects on neuronal activity.
Test Stimulation:
Once the electrode is properly positioned, a temporary test stimulation is performed to determine its therapeutic impact on Parkinson's symptoms and any potential side effects, such as tingling or muscle contractions.
Implantation of Pulse Generator:
If the test stimulation is successful, a tiny incision is made in the chest or abdomen to implant a pulse generator (neurostimulator) beneath the skin.
The pulse generator is connected to the electrode leads via insulated wires that are tunneled under the skin and fastened.
Closure and Postoperative Care:
Sutures or staples are used to close the scalp and skin incisions, which are then covered with a sterile dressing.
The patient is taken to a recovery area for monitoring and observation.
Post-operative imaging investigations may be performed to confirm electrode placement and evaluate surgical complications.
Programming and Follow-up:
In the weeks and months following surgery, the DBS system is programmed and tweaked to improve symptom control while reducing side effects.
The patient has regular follow-up meetings with the neurology and neurosurgery departments to ensure continued care and adjustment of the DBS settings as necessary.
In summary, the DBS surgical process entails accurate targeting of brain regions, electrode placement, pulse generator implantation, and post-operative programming to maximize therapeutic results. To assure safety and efficacy, the treatment uses rigorous attention to detail as well as modern neuroimaging and monitoring tools.

Research evidence consistently supports its usefulness in lowering tremors, rigidity, bradykinesia, and motor fluctuations, as well as allowing medication reduction and improving total functional independence. While individual reactions to DBS may differ, the overall body of evidence shows that it has considerable therapeutic benefits for qualified Parkinson's patients.
The Impact of Deep Brain Stimulation (DBS) on Motor and Non-Motor Symptoms of PD
Deep Brain Stimulation (DBS) has a considerable influence on both motor and non-motor symptoms of Parkinson's disease, providing comprehensive relief to many patients. Here is a thorough overview:
Motor Symptoms:
Tremors:
DBS effectively lowers tremors, which are involuntary shaking motions that many people with Parkinson's disease suffer from. Patients frequently report a considerable reduction in tremor frequency and severity following DBS surgery.
Bradykinesia (Slowness of Movement):
DBS can help with bradykinesia, a condition that causes voluntary motions to slow down. Patients frequently notice faster and more fluid motions, which improves mobility and daily functioning.
Rigidity:
DBS reduces muscle stiffness or rigidity, which is a frequent sign of Parkinson's disease. Patients may notice increased flexibility and ease of movement, which improves comfort and quality of life.
Motor Fluctuations:
DBS lowers motor fluctuations, such as "on-off" occurrences and dyskinesias (involuntary motions), by enabling more steady and consistent symptom control. This causes smoother transitions between mobility and immobility stages throughout the day.
Non-motor Symptoms:
Cognitive Function:
Although DBS is primarily used to treat motor complaints, several studies suggest that it may also improve cognitive performance. However, the influence of DBS on cognitive function is less well understood than its effects on motor symptoms.
Mood and Behavior:
After surgery, some people claim that DBS can help improve their:
- mood
- anxiety
- depression
However, DBS may occasionally cause negative mood changes or mental symptoms, emphasizing the significance of careful patient selection and monitoring.
Speech and Swallowing:
DBS may enhance speech intelligibility and swallowing function in some individuals, notably those suffering from Parkinson's disease. However, stimulation-induced side effects such as dysarthria (speech difficulties) and dysphagia (swallowing issues) might develop in a subgroup of patients and must be carefully managed.
Sleep Disturbances:
DBS has been linked to improved sleep quality and fewer sleep disturbances often reported by Parkinson's patients, including insomnia or excessive daytime sleepiness. Individual reactions to DBS may vary, and not all patients may see changes in their sleep patterns.
Autonomic Dysfunction:
Certain non-motor symptoms of Parkinson's disease, such as orthostatic hypotension and urinary dysfunction, may respond differently to DBS. While DBS primarily treats motor symptoms, its effect on non-motor symptoms may be impacted by illness severity and specific patient characteristics.
In conclusion, Deep Brain Stimulation for PD (Parkinson's disease) effectively reduces motor symptoms such as tremors, bradykinesia, stiffness, and motor fluctuations. While DBS may have a positive effect on certain non-motor symptoms such as mood, speech, swallowing, and sleep difficulties, the influence on non-motor symptoms is less well-established and may differ between individuals. Careful patient selection, careful pre-operative evaluation, and continued post-operative management are critical for improving outcomes and avoiding potential side effects of DBS therapy.
Rehabilitation and Recovery Process after DBS Surgery
The rehabilitation and recovery process following Deep Brain Stimulation for PD (Parkinson's disease) is critical to attaining the best possible results. Here is a thorough overview:
