Parkinson's FAQs

1. Can Parkinson’s Disease Be Prevented?

1. WHAT IS ONE OF THE COMMON QUESTIONS YOUR CLIENTS ASK?

At this time, there’s no proven way to prevent Parkinson’s disease.

Parkinson’s can develop because of genetics, biological changes we don’t fully understand yet, or a combination of both, and right now, there’s no reliable way to predict who will develop it or stop it from happening.  Some research has found links between higher Parkinson’s risk and certain environmental exposures or occupations—like farming, welding, or long-term contact with specific chemicals. But those connections are not a guarantee: most people in these jobs never develop Parkinson’s, and avoiding an exposure doesn’t mean someone is “fully protected.”

The good news is that research into risk factors and possible protective habits is moving fast. But today, no lifestyle change, supplement, or intervention has been shown to definitively prevent Parkinson’s.

2. How Do I Take Care of Myself?

2. WHAT IS ONE OF THE COMMON QUESTIONS YOUR CLIENTS ASK?

If you’ve been diagnosed with Parkinson’s, the most important step is this: don’t go it alone.
Working closely with your healthcare team—and following a plan built for you—can make a real difference in how you feel day to day, how well symptoms are managed, and how confidently you move through life.

Take meds as prescribed (and on time)

Medication is one of the strongest tools we have for managing Parkinson’s symptoms. Taking it consistently, and on schedule, can reduce “off” time and help your day feel more steady and predictable.  If something feels off—side effects, wearing off sooner than expected, or new symptoms—say it early. You’re not complaining. You’re helping your care team fine-tune the plan.

Keep regular follow-ups

Routine visits help track changes, fine-tune medications, and stay ahead of new challenges.

Report new or worsening symptoms early


Parkinson’s can affect movement, sleep, mood, thinking, energy, and more. Many symptoms are treatable—especially when addressed early—so don’t wait to bring changes to your doctor’s attention.

3. WHAT IS ONE OF THE COMMON QUESTIONS YOUR CLIENTS ASK?

3. WHAT IS ONE OF THE COMMON QUESTIONS YOUR CLIENTS ASK?

Parkinson’s disease is a progressive neurological condition, which means changes in the brain develop gradually over time. Progression is usually slow and highly individual, and many people live a normal—or near-normal—lifespan with Parkinson’s, especially with today’s treatments and care.  In the early stages, most people need little to no assistance and can continue to live independently, work, drive, and stay active. Symptoms are often mild and respond well to treatment.

As Parkinson’s progresses, medication becomes a key part of symptom management. Many people respond strongly, especially to levodopa-based therapies, once the right medication plan and dosing schedule are found. These treatments can reduce symptoms and help preserve function for years.

Over time, symptoms may become more complex and medication effects can fluctuate, which often means adjustments are needed. Care commonly becomes more personalized and may include a mix of medications, physical therapy, exercise, and supportive care.  In later stages, daily activities can become more challenging and extra support may be needed. Even then, many people continue to benefit from treatment and maintain a meaningful quality of life with the right medical care and a strong support system.


4. What’s the Outlook for Parkinson’s Disease?

4. WHAT IS ONE OF THE COMMON QUESTIONS YOUR CLIENTS ASK?

If you’re diagnosed with Parkinson’s today, the outlook is often more hopeful and manageable than people expect.

Parkinson’s is progressive, but it’s usually slow-moving and highly individual, and many people live a normal or near-normal lifespan, especially with modern treatment and good follow-up care.

For a long time, most people can still work, drive, stay active, and live independently. Medications (often including Carbidopa/Levodopa often called Sinemet) can make a big difference, especially when the right plan—and timing—is dialed in.

Parkinson’s changes the roadmap, but it doesn’t erase your life. It means learning a new rhythm, building the right support, and moving forward—one steady step at a time. 

5. Can parkinson's affect my thinking or memory ?

5. WHAT IS ONE OF THE COMMON QUESTIONS YOUR CLIENTS ASK?

Yes — Parkinson’s can affect thinking and memory for some people, but it doesn’t happen the same way for everyone.

Many people notice changes like slower thinking, trouble multitasking, word-finding issues, or feeling more mentally “foggy,” especially when tired, stressed, or in an “off” period. For others, thinking and memory stay strong for many years.

The important part: if you notice changes, bring them up early. There are often practical strategies, medication adjustments, sleep support, and therapies that can help—and you deserve support without shame or fear.

6. Can Parkinson’s affect mood and anxiety?

6. WHAT IS ONE OF THE COMMON QUESTIONS YOUR CLIENTS ASK?

Yes — Parkinson’s can absolutely affect mood and anxiety, and it’s more common than many people realize.

This isn’t just “how you’re handling it.” Parkinson’s can change brain chemistry and nervous system function, and on top of that, living with uncertainty can be emotionally heavy. People may experience anxiety, depression, irritability, or feeling overwhelmed, sometimes even before motor symptoms start.

The good news: these symptoms are real, treatable, and worth addressing early. If your mood shifts or anxiety ramps up, tell your doctor—support, therapy, medication adjustments, and lifestyle tools can make a meaningful difference.

7. What and How do I tell friends, family, and coworkers?

Keep it simple, steady, and on your terms. You don’t owe anyone every detail—just enough to give context and reduce awkwardness.

Example (works for most people):
“I wanted to share something important—I’ve been diagnosed with Parkinson’s. I’m doing okay and getting good care. You may notice symptoms sometimes, like tremor or stiffness, but I’m managing it. I’ll let you know if I ever need support.”

7. WHAT IS ONE OF THE COMMON QUESTIONS YOUR CLIENTS ASK?

Suggest to keep it simple, steady, and on your terms. You don’t owe anyone every detail—just enough to give context and reduce awkwardness.

Example (works for most people):
“I wanted to share something important—I’ve been diagnosed with Parkinson’s. I’m doing okay and getting good care. You may notice symptoms sometimes, like tremor or stiffness, but I’m managing it. I’ll let you know if I ever need support.”

8. What should I share with my employer?

8. WHAT IS ONE OF THE COMMON QUESTIONS YOUR CLIENTS ASK?

When you feel the time comes, suggest to keep it simple, professional, and calm. You may want to begin with your direct supervisor, and if needed, involve Human Resources or an Employee Relations (ER) representative (especially in a larger organization).

Something along the lines of:  “I wanted to share that I’ve been diagnosed with Parkinson’s. I’m under medical care and fully able to perform my role. You may notice occasional symptoms like tremor, stiffness, or fatigue, but I’m managing them. If I ever need a small adjustment to stay at my best, I’ll communicate early and follow up through the appropriate channels."

Reminder: You are protected at work. Parkinson’s is widely recognized as a disability, and laws and workplace policies exist to prevent unfair treatment and support reasonable accommodations if needed.

That doesn’t mean you have to lead with legal language—but it does mean you should feel confident advocating for yourself. If support or adjustments ever become necessary, you may need to engage with your company’s HR team or Employee Relations (ER) representative to document needs and follow the proper process.

And if you ever feel you’re being treated differently or unfairly because of your diagnosis, it’s reasonable to document concerns, involve HR/ER, and—if needed—consult an employment attorney to understand and protect your rights.

Clinical Note: Can be caused by Parkinson’s disease or other conditions like MSA, PSP, medications, or vascular disease.
Why It Matters: Describes a symptom pattern—not a single diagnosis—so evaluation and treatment change.

Parkinson’s Disease (PD)
Plain-English: A progressive condition affecting movement, mood, thinking, and many body systems.
Clinical Note: Characterized by dopamine neuron loss in the substantia nigra and Lewy body pathology.
Why It Matters: Requires a whole-person, multidisciplinary approach.

Parkinson’s Disease Dementia (PDD)
Plain-English: Cognitive decline that develops after years of Parkinson’s disease.
Clinical Note: Associated with widespread Lewy body pathology.
Why It Matters: Impacts independence, caregiving, and long-term planning.

Parkinson’s Psychosis
Plain-English: Parkinson’s-related hallucinations, delusions, or confusion.
Clinical Note: Often medication-influenced and linked to Lewy pathology progression.
Why It Matters: Early recognition reduces safety risk and caregiver strain.

Postural Hypotension
Plain-English: Feeling dizzy or lightheaded when standing up.
Clinical Note: Often due to autonomic dysfunction or Parkinson’s medications.
Why It Matters: A common and treatable cause of falls.

Postural Instability
Plain-English: Trouble maintaining balance, especially when turning.
Clinical Note: Reflects axial motor system dysfunction.
Why It Matters: Strong predictor of falls.

Postural Tremor
Plain-English: Tremor that appears while holding a position—like holding arms out or holding a cup.
Clinical Note: May overlap with essential tremor or occur alongside Parkinson’s tremor patterns.
Why It Matters: Explains tremor that doesn’t match “resting tremor only.”

Progressive Supranuclear Palsy (PSP)
Plain-English: A condition that can resemble Parkinson’s but often causes early falls and eye movement problems.
Clinical Note: Features gaze palsy, axial rigidity, early falls, and limited levodopa response.
Why It Matters: Frequently misdiagnosed early; planning priorities differ from PD.

REM Atonia
Plain-English: Normal muscle paralysis during dream sleep.
Clinical Note: Loss of REM atonia causes REM Sleep Behavior Disorder.
Why It Matters: A key marker of synuclein-related disease.

REM Sleep Behavior Disorder (RBD)
Plain-English: Acting out dreams—talking, yelling, punching, or kicking.
Clinical Note: Loss of REM atonia due to brainstem dysfunction.
Why It Matters: One of the strongest early markers of synucleinopathy.

Rigidity
Plain-English: Muscle stiffness that makes movement feel tight, resistant, or uncomfortable.
Clinical Note: A core motor feature caused by increased muscle tone from basal ganglia dysfunction.
Why It Matters: Contributes to pain, reduced motion, and fatigue—and can improve with treatment.

Sensory Neuropathy
Plain-English: Numbness, tingling, or burning sensations in the limbs.
Clinical Note: May relate to vitamin deficiencies, diabetes, or medications.
Why It Matters: Can worsen balance and gait instability.

Sialorrhea
Plain-English: Drooling due to reduced automatic swallowing.
Clinical Note: Caused by bradykinesia of throat muscles.
Why It Matters: Socially distressing but very treatable.

Skin Biopsy (Phosphorylated Alpha-synuclein)
Plain-English: A small skin sample used to detect abnormal Parkinson’s protein.
Clinical Note: Detects phosphorylated alpha-synuclein in peripheral nerves.
Why It Matters: Enables biological confirmation without brain imaging.

Sleep Fragmentation
Plain-English: Frequent nighttime awakenings that disrupt sleep.
Clinical Note: Common due to RBD, pain, nocturia, and medication effects.
Why It Matters: Worsens fatigue, cognition, and mood.

Speech-Language Pathologist (SLP)
Plain-English: A therapist who helps with speech, voice, and swallowing.
Clinical Note: Addresses hypophonia, articulation, and dysphagia.
Why It Matters: Early involvement preserves communication and safety.

STN (Subthalamic Nucleus)
Plain-English: A deep brain target often used for DBS.
Clinical Note: STN stimulation can reduce medication needs and improve motor fluctuations.
Why It Matters: Helps patients understand DBS choices and tradeoffs.

Substantia Nigra
Plain-English: A deep brain region critical for movement control.
Clinical Note: Site of dopamine neuron loss in Parkinson’s disease.
Why It Matters: Central to the biology of PD.

Talk Test (Exercise Intensity)
Plain-English: You should be able to talk, but not sing, during exercise.
Clinical Note: Corresponds to moderate-to-vigorous aerobic intensity.
Why It Matters: Matches intensity used in Parkinson’s exercise studies.

Tremor (Resting)
Plain-English: Shaking that happens when the limb is at rest and eases with movement.
Clinical Note: Rhythmic oscillation from basal ganglia–thalamic circuit imbalance.
Why It Matters: Common early sign, but some people never develop tremor.

Urinary Urgency
Plain-English: A sudden strong need to urinate that’s hard to delay.
Clinical Note: Common in PD due to autonomic bladder dysfunction and overactivity.
Why It Matters: Impacts sleep, travel confidence, and daily quality of life.

Visual Misperceptions
Plain-English: Seeing shadows, movement, or shapes that aren’t fully formed hallucinations.
Clinical Note: Often precede hallucinations in Parkinson’s disease.
Why It Matters: Early recognition helps guide medication review and monitoring.
