How Deep Brain Stimulation (DBS) Helps in Parkinson’s & Tremor Control

Deep brain stimulation (DBS) is a treatment that involves the use of an implanted device that delivers an electrical current directly to areas of your brain. It is a United States Food and Drug Administration-approved treatment for individuals dealing with movement conditions. It was first approved in the 1990s for the treatment of movement disorders.

As of 2019, experts speculate that approximately 160,000 people have undergone DBS implantation since the 1980s. They also estimate that around 12,000 procedures happen annually.

Why Would Someone Need Deep Brain Stimulation?

A neurologist or movement disorder specialist in Delhi can recommend DBS to an individual with movement disorders:

1. Parkinson's disease (a movement disorder of the nervous system)
2. Obsessive-compulsive disorder
3. Essential tremor (rhythmic, uncontrolled shaking)
4. Conditions that cause dystonia, like Meige syndrome
5. Epilepsy
6. Tourette syndrome (involves repetitive movements)

How Does DBS Help in Parkinson's and Tremor Management?

DBS helps in Parkinson's and tremor by offering the following benefits.

1. Help Control Tremors

It helps by regulating abnormal brain signals that cause tremors. This can lower shaking in the hands, legs, and other body parts and improve daily function.

2. Support Better Movement

DBS helps by enhancing motor control through targeted brain stimulation. This support reduces stiffness, slowness, and moving difficulty.

3. May Decrease the Need for Medication

A doctor can recommend a reduced dose of the Parkinson’s drugs. This can lower side effects such as nausea and involuntary movements.

4. Help Provide Long-Term Relief

Unlike medication that may become less effective over time, DBS can provide ongoing symptom management for a longer duration.

5. Improve Quality of Life

It supports improvement in motor symptoms and independence. This can improve day-to-day life activities and social engagement.

6. Offer Personalized Treatment

The stimulation settings can be adjusted according to the severity of the individual's condition. This helps support optimal symptom management.

7. Supports Emotionally

Some individuals report improved mood and sleep, likely due to improved brain function and symptom relief.

Note: DBS does not cure Parkinson's disease or stop its progression. However, it only supports managing ongoing symptoms.

Which Symptoms of Parkinson’s Improve Most After DBS

It helps manage the following symptoms by disrupting abnormal brain signals responsible for them:

1. Helps reduce tremors.
2. Improves the speed and fluidity of voluntary movements.
3. Help relax stiff muscles.
4. Lowers involuntary movements due to long-term levodopa use.
5. Encourages patients to achieve better symptom control and mobility.

How Does DBS Actually Work for Parkinson’s & Tremor?

Parkinson’s and dystonia are some movement disorders that can cause tremor. They may happen when certain brain cells (neurons) don’t work properly.

 When other treatments are ineffective, a movement disorder specialist in Delhi may recommend DBS therapy 
↓

 DBS involves implanting tiny electrodes in specific brain areas. These are connected to a pacemaker-like device under the skin in the chest. 
↓
This device sends mild electrical pulses to help brain cells. This supports better communication between the cells.
↓

 These signals trigger the activity of underactive neurons.

This helps reduce symptoms and better control movement. 

Note: While the exact mechanism of DBS working is not fully understood, experts say it has helped many individuals regain smoother, more controlled motion.

Conditions that Might be Addressed With DBS

Studies show that DBS has the potential to alleviate the following conditions:

1. Anxiety
2. Schizophrenia (affects how people think, feel, and behave)
3. Severe pain disorders
4. Severe, medication-resistant depression
5. Cluster headaches
6. Eating disorders

How Safe Is Deep Brain Stimulation?

It is generally considered to be low risk when performed in carefully selected patients by experienced surgical teams, like at IBS Hospital. However, like any type of surgery, it has the risk of complications. 

• Misplacement of the wires with the electrodes
• Bleeding in the brain
• Breathing difficulty
• Nausea
• Heart problems
• Seizure
• Stroke
• Infection

Conclusion

There is no known cure for Parkinson's disease; however, treatments can manage symptoms such as tremors. The most well-known effective medical treatment is the prescription-based medication Levodopa/carbidopa, which restores dopamine in the brain.

But when these treatments are no longer effective, a doctor can recommend DBS to help manage the symptoms and improve quality of life. All you need is to follow your doctor's advice for the best outcome.

FAQs

Q1: Does DBS stop tremors?
A: DBS does not cure tremors; however, it works by sending electrical signals to the brain areas responsible for tremors. This helps regulate those abnormal signals, helping reduce shaking of shaking in your hands, legs, and other body parts.

Q2: What is the success rate of deep brain stimulation for Parkinson's patients?
A: Studies have observed that around 75% of Parkinson's patients who receive DBS notice improvement in symptoms such as tremors, stiffness, and slow movements. The benefits often last for many years and can lower the dependence on medications. DBS for Parkinson’s patients is associated with approximately a 51% 10-year survival rate. 

Q3: What device stops tremors in Parkinson's patients?
A: The device used is a Deep Brain Stimulation (DBS) system. It involves the use of electrodes implanted in the brain connected to a small generator under the skin. This device sends electrical impulses to control abnormal brain activity, causing tremors.
