Parkinson's Disease

Parkinson's disease is a progressive neurodegenerative disorder that affects movement. It develops when neurons in a specific area of the brain gradually break down or die. These neurons produce dopamine, a chemical messenger that helps coordinate movement. As dopamine levels decrease, abnormal brain activity occurs, leading to the characteristic motor symptoms of Parkinson's disease. The condition typically develops gradually, sometimes starting with a barely noticeable tremor in just one hand. While tremor is a well-known sign, the disorder also commonly causes stiffness and slowing of movement. Parkinson's disease symptoms worsen as the condition progresses over time, significantly impacting quality of life. Although there is no cure, medications and various therapies can markedly improve symptoms.

What Causes It?

Genetic factors - Specific genetic mutations have been identified that can cause Parkinson's disease, though these are relatively rare except in cases with a strong family history of the condition.

Environmental triggers - Exposure to certain toxins or environmental factors may increase the risk of Parkinson's disease, though the exposure generally needs to be significant.

Presence of Lewy bodies - Clumps of specific substances (alpha-synuclein protein) within brain cells are microscopic markers of Parkinson's disease.

Loss of dopamine-producing cells - The death of neurons that produce dopamine, a chemical messenger that helps coordinate movement, is the primary cause of motor symptoms.

Age - Parkinson's disease risk increases with age, with onset typically after age 60, though about 5-10% of cases are early-onset occurring before age 50.

Sex - Men are more likely to develop Parkinson's disease than women, possibly due to hormonal or occupational exposure differences.

Head injuries - Traumatic brain injury may increase the risk of developing Parkinson's disease years after the injury.

Declining estrogen levels - The reduction in estrogen levels in women after menopause may explain the higher rate in men versus women.

Agricultural work - Exposure to pesticides and herbicides in farming has been linked to higher rates of Parkinson's disease.

Industrial chemicals - Exposure to solvents, metals, and other industrial chemicals may increase risk.

Signs & Symptoms

Tremor - Usually begins in a limb, often the hand or fingers, typically occurring at rest and decreasing with purposeful movement.

Bradykinesia (slowed movement) - Over time, Parkinson's disease may reduce ability to move, making simple tasks difficult and time-consuming.

Rigid muscles - Muscle stiffness can occur in any part of the body, causing pain and limiting range of motion.

Impaired posture and balance - Posture may become stooped, with increased fall risk due to balance problems.

Loss of automatic movements - Decreased ability to perform unconscious movements like blinking, smiling, or swinging arms when walking.

Speech changes - Speaking softly, quickly, slurring, or hesitating before talking; speech may become more monotone.

Writing changes - Handwriting may become small, cramped, and difficult to read (micrographia).

Non-motor symptoms - Including depression, cognitive changes, sleep problems, constipation, and loss of sense of smell.

Facial masking - Reduced facial expression due to affected facial muscles, sometimes called "masked face."

Freezing - Temporary inability to move, especially when initiating movement or encountering doorways or crowded spaces.

Voice changes - Voice becoming softer, more monotone, hoarse, or breathiness while speaking.

How We Diagnose

Our specialists use advanced diagnostic methods to accurately identify and assess your condition

Neurological Examination

A neurologist will assess your symptoms and medical history, then conduct a detailed examination of your nervous system. They will evaluate your movement, muscle tone, gait, balance, and simple hand tasks. They'll also check for signs like facial expression changes, tremor characteristics, and response to passive movement.

DaTscan (Dopamine Transporter Scan)

This specialized brain imaging technique uses a radioactive tracer to visualize dopamine transporters in the brain. It can help differentiate Parkinson's disease from other conditions that cause similar symptoms, such as essential tremor.

MRI or CT Scan

These imaging tests may be used to rule out other conditions that could cause similar symptoms, such as stroke, brain tumors, or hydrocephalus. They typically appear normal in Parkinson's disease but help exclude other diagnoses.

Response to Parkinson's Medication

A significant improvement in symptoms after taking levodopa, the primary treatment for Parkinson's disease, strongly supports the diagnosis. This "levodopa challenge test" may be used in uncertain cases.

Olfactory Testing

Since loss of smell (hyposmia) often occurs early in Parkinson's disease, testing the sense of smell may provide supportive evidence for diagnosis, though it's not definitive on its own.

Sleep Study

REM sleep behavior disorder, where people act out their dreams during sleep, is strongly associated with Parkinson's disease and often precedes motor symptoms by years. A sleep study may identify this condition.

Treatment Options

Personalized treatment plans tailored to your specific needs and condition

Medications

Several types of medications can help manage the symptoms of Parkinson's disease. Levodopa, the most effective, is converted to dopamine in the brain. Dopamine agonists mimic dopamine effects but are less effective than levodopa. MAO-B inhibitors help prevent the breakdown of dopamine in the brain. COMT inhibitors prolong levodopa's effect. Anticholinergics help control tremor, and amantadine provides short-term relief of symptoms.

Surgical Interventions

Deep brain stimulation (DBS) is the primary surgical option for advanced Parkinson's disease. It involves implanting electrodes in specific areas of the brain and connecting them to a generator implanted in the chest. The generator sends electrical pulses to the brain to reduce symptoms. DBS is typically considered when medications are no longer effectively controlling symptoms or are causing significant side effects.

Lifestyle Modifications and Physical Therapy

Regular exercise has been shown to help manage many Parkinson's symptoms and may slow disease progression. Physical therapy can improve mobility, flexibility, and balance. Occupational therapy helps adapt daily activities to maintain independence. Speech therapy addresses voice and swallowing issues. A balanced diet and proper hydration support overall health and medication effectiveness.

Supportive Therapies

Various complementary approaches can help manage symptoms and improve quality of life. These include tai chi or yoga for balance and flexibility, massage for muscle stiffness, acupuncture for pain relief, meditation for stress reduction, and music or art therapy for emotional well-being and motor control.

Home Remedies

Regular Exercise

Engage in regular physical activity suited to your abilities. Walking, swimming, tai chi, dancing, or cycling can help maintain mobility, balance, flexibility, and strength. Aim for at least 150 minutes of moderate exercise weekly, divided into manageable sessions. Exercise has been shown to potentially slow Parkinson's progression and improve symptoms.

Balanced Nutrition

Eat a diet rich in fruits, vegetables, whole grains, and lean protein. Stay well-hydrated. Some people with Parkinson's benefit from adjusting protein intake around medication times, as protein can affect levodopa absorption. Consider working with a dietitian familiar with Parkinson's to develop an optimal eating plan.

Sleep Hygiene

Establish a regular sleep schedule and create a relaxing bedtime routine. Make your bedroom comfortable, dark, and quiet. Avoid caffeine, alcohol, and screen time before bed. Address symptoms that disrupt sleep, such as nighttime rigidity or frequent urination, with your healthcare provider.

Stress Management

Practice stress-reduction techniques like deep breathing, meditation, progressive muscle relaxation, or guided imagery. Stress can worsen Parkinson's symptoms, particularly tremor. Consider joining a support group to connect with others facing similar challenges.

Home Modifications

Make your living environment safer and more accessible. Remove trip hazards like loose rugs, install grab bars in bathrooms, improve lighting, and consider adaptive equipment like button hooks, weighted utensils, or dressing aids to maintain independence with daily activities.

Prevention Tips

Take medications exactly as prescribed and on schedule to maintain consistent symptom control.

Attend regular follow-up appointments with your neurologist to monitor disease progression and adjust treatment as needed.

Work with a physical therapist to develop and maintain an exercise program tailored to your specific needs and abilities.

Engage in activities that challenge your brain, such as puzzles, reading, or learning new skills, to support cognitive health.

Join a Parkinson's support group to share experiences and coping strategies with others who understand your challenges.

Address non-motor symptoms like depression, anxiety, or sleep problems promptly, as these can significantly impact quality of life.

Take steps to prevent falls by removing hazards at home, using assistive devices if needed, and practicing balance exercises.

Maintain social connections and activities you enjoy to support emotional well-being and prevent isolation.

Consider speech therapy early on to maintain communication abilities, even before significant speech changes occur.

Work with an occupational therapist to learn energy conservation techniques and ways to adapt daily activities as needs change.

Stay informed about new research and treatment options through reputable Parkinson's disease organizations.

Surgical Solutions

Advanced surgical procedures performed by our expert specialists

Deep Brain Stimulation (DBS)

The most common surgical treatment for Parkinson's disease, involving the implantation of electrodes in specific areas of the brain (typically the subthalamic nucleus or globus pallidus). These electrodes connect to a generator implanted in the chest that sends electrical pulses to regulate abnormal neural activity. DBS can significantly reduce tremor, rigidity, and bradykinesia, and may allow for medication reduction. It's typically considered when medications are causing significant side effects or no longer adequately controlling symptoms.

MRI-Guided Focused Ultrasound

A non-invasive procedure that uses focused sound waves to precisely target and destroy small areas of brain tissue responsible for tremor. Currently approved for treating tremor-dominant Parkinson's disease, this procedure doesn't require incisions or implants. It's typically performed on one side of the brain and may be an option for patients who aren't candidates for DBS.

Levodopa-Carbidopa Intestinal Gel (LCIG)

A method of delivering levodopa directly into the small intestine through a tube, providing continuous medication delivery. This surgical procedure involves placing a tube through the abdominal wall into the intestine, connected to a portable pump. LCIG can help reduce "off" periods and dyskinesias in advanced Parkinson's disease by maintaining steady medication levels.

Lesioning Procedures (Pallidotomy/Thalamotomy)

These less commonly performed procedures involve creating small, precise lesions in specific brain areas (globus pallidus or thalamus) to reduce Parkinson's symptoms. While historically important, they have largely been replaced by DBS, which provides similar benefits with the advantage of being adjustable and reversible.
