Parkinson's Disease

Understanding Parkinson’s Disease

If you or someone you love has noticed shaking hands, stiffness, or slowness that seems unusual, you might be concerned about Parkinson’s disease. These concerns are valid, and seeking answers is an important first step.

Parkinson’s disease is a condition that affects how your body moves. It happens when special nerve cells in the brain stop working properly. The good news is that treatments exist to help manage symptoms and maintain quality of life.

This page explains Parkinson’s disease in simple, easy-to-understand language. It helps you recognize warning signs and learn about treatments available. For personalized medical advice and diagnosis, always consult with a qualified healthcare professional.

What is Parkinson’s Disease?

How the Brain Works Normally vs. With Parkinson’s

Your brain controls movement through a special chemical called dopamine. According to the National Institute on Aging, dopamine acts like a messenger, telling your muscles when and how to move smoothly.

In a healthy brain:

• Dopamine levels stay steady

• Movements are smooth and coordinated

• You can start and stop movements easily

• Muscles relax when you want them to

With Parkinson’s disease:

• Brain cells that make dopamine start dying

• Dopamine levels drop

• Movements become shaky, slow, and stiff

• It becomes harder to start or stop movements

• Your body doesn’t move as smoothly

This is why people with Parkinson’s develop shaking, stiffness, and slowness of movement.

Who Gets Parkinson’s?

Parkinson’s typically affects people over 60, but it can happen to younger people too. The Parkinson’s Foundation reports that millions of people worldwide have Parkinson’s disease.

Risk factors include:

• Getting older (most common after age 60)

• Male gender (more common in men than women)

• Family history (having relatives with Parkinson’s)

• Head injuries in the past

• Exposure to certain pesticides

• Environmental factors

Early Warning Signs: Know What to Watch For

Parkinson’s symptoms often appear slowly and can be mistaken for normal aging. But knowing the signs helps you catch the disease early, which leads to better treatment outcomes.

The 10 Most Common Early Signs

➤ TREMOR (Shaking)

What it is: Shaking or trembling, usually in your hand, arm, or leg

Important details:

• Often starts in one hand or arm

• Happens when your limb is relaxed and resting

• Becomes more noticeable when you’re not using it

• Gets worse when you’re stressed or tired

Example: Your hand shakes while sitting and reading, but stops when you pick something up to use it.

➤ SLOWNESS OF MOVEMENT

What it is: Actions take much longer than they should

What gets harder:

• Walking (slower, smaller steps)

• Writing (becomes smaller and slower)

• Getting out of bed or chairs

• Buttoning clothes

• Eating

• Any activity that requires fine motor skills

Example: It takes twice as long as normal to get dressed in the morning, or your handwriting becomes noticeably smaller.

➤ MUSCLE STIFFNESS (Rigidity)

What it is: Your muscles feel tight and resistant to movement

How it feels:

• Muscles feel tense and won’t relax

• Moving feels like working against resistance

• Can be painful or cause cramping

• Neck, shoulders, and arms commonly affected

• Makes it hard to turn over in bed

Example: Your shoulder and neck feel constantly tight, and turning your head feels stiff and difficult.

➤ BALANCE AND POSTURE PROBLEMS

What it is: Difficulty keeping your balance and changes in how you stand

What happens:

• You lean forward or to one side when standing

• Stooped posture becomes noticeable

• Walking feels unsteady

• Higher risk of falling

• Difficulty recovering your balance

Example: People notice you’ve started walking bent forward, or you fall more easily than before.

➤ FACIAL CHANGES

What it is: Your face becomes less expressive

What people notice:

• Fewer facial expressions

• Less blinking than usual

• Face appears frozen or mask-like

• Smile becomes less visible

• Eye contact may seem different

Example: People say you look angry or sad, but you’re not—your face just doesn’t show expression.

➤ VOICE AND SPEECH CHANGES

What it is: Your voice becomes softer and speech changes

What happens:

• Voice becomes quieter or monotone

• Speech slows down

• Hard to hear what you’re saying

• Less variation in tone (sounds robotic)

• Difficulty with loud or clear speech

Example: People ask you to speak up, or say your voice sounds quieter and flatter than before.

➤ HANDWRITING CHANGES

What it is: Your handwriting becomes noticeably smaller and harder to read

What you notice:

• Writing becomes progressively smaller

• Handwriting becomes cramped and tight

• Harder to read your own writing

• Takes longer to write

• Mid-sentence writing may get even smaller

Example: You start the sentence normally, but by the end, your writing is so small it’s hard to read.

➤ SLEEP PROBLEMS

What it is: Trouble sleeping through the night

Common problems:

• Waking up frequently during night

• Restless leg movements

• Vivid, intense dreams

• Difficulty turning over in bed

• Waking up early and can’t fall back asleep

• Feeling very tired during the day

Example: You wake up 5-10 times a night or feel like you’re fighting your legs while sleeping.

➤ LOSS OF SMELL

What it is: Reduced ability to smell

What you notice:

• Food tastes less flavorful

• Can’t smell familiar scents

• Loss of smell may come YEARS before other symptoms

• Often goes unnoticed initially

Example: You can’t smell flowers, coffee, or other things you used to smell easily.

➤ MOOD AND MENTAL CHANGES

What it is: Depression, anxiety, or mood changes

What happens:

• Feeling sad or hopeless

• Constant worry or anxiety

• Difficulty concentrating

• Loss of interest in things you enjoyed

• Difficulty making decisions

Example: You feel persistently sad or anxious without clear reason, or lose interest in hobbies you loved.

How Parkinson’s Disease is Diagnosed

Early diagnosis leads to better management and treatment outcomes.

Step-by-Step Diagnostic Process

STEP 1: Medical History
Your doctor asks about:

• When did symptoms start?

• What symptoms have you noticed?

• Do family members have Parkinson’s?

• What medicines do you take?

• Other health conditions?

STEP 2: Physical Exam
Your doctor will check:

• Your reflexes and muscle strength

• How you walk and your posture

• Your coordination and balance

• Eye movement

• Tremor or stiffness

STEP 3: Neurological Testing
Your doctor assesses:

• Speed of your movements

• Muscle tone and stiffness

• Ability to stand and walk

• Reflexes

• Balance

STEP 4: Brain Scans (When Needed)
Sometimes ordered to rule out other conditions:

• MRI scan (shows brain structure clearly)

• CT scan (faster brain imaging)

• Special imaging to detect dopamine levels (in research settings)

STEP 5: Blood Tests
To rule out other causes of symptoms:

• Thyroid problems

• Vitamin deficiencies

• Metabolic issues

• Other conditions

STEP 6: Exclusion of Other Conditions
Doctors also check for:

• Essential tremor (different type of shaking)

• Medication side effects

• Stroke or brain tumor

• Other neurological conditions

For detailed diagnostic information, visit the National Institute on Aging.

What to Expect at Your Evaluation

• Appointment typically takes 1-2 hours

• Bring all medications and medical records

• Bring a family member who’s noticed changes

• Wear loose, easy-to-move-in clothing

• Be prepared to walk around a bit

• Ask questions about anything unclear

Treatment Options for Parkinson’s Disease

While there’s no cure yet, treatments can significantly reduce symptoms and maintain quality of life—especially when started early.

Medications That Replace Dopamine

The Gold Standard: Levodopa (L-DOPA)

According to recent research, levodopa remains the most effective medication for Parkinson’s symptoms. It’s been used successfully for over 50 years.

How it works:

• Levodopa is converted into dopamine in the brain

• Restores dopamine levels

• Reduces shaking, stiffness, and slowness

Combined with:

• Carbidopa: Helps levodopa reach the brain better

Given as:

• Pills taken multiple times daily

• Patches applied to skin

• Liquid form

• Recent innovation: once-weekly injections (newer option)

What it helps:

• Tremor and shaking

• Stiffness and rigidity

• Slowness of movement

• Posture and balance

Other Movement Medications

Dopamine Agonists (mimic dopamine in the brain)

• Pramipexole

• Ropinirole

• Rotigotine (patch form)

MAO Inhibitors (preserve dopamine)

• Selegiline

• Rasagiline

COMT Inhibitors (extend dopamine action)

• Entacapone

Anticholinergics (reduce tremor)

• Benztropine

• Trihexyphenidyl

Medications for Non-Movement Symptoms

Surgical Treatments (Advanced Options)

Deep Brain Stimulation (DBS)

• Electrodes placed in brain

• Send electrical signals to reduce symptoms

• Used when medications become less effective

• Can significantly improve movement symptoms

When considered:

• Usually after 5-10 years on medication

• When symptoms not well-controlled with medicines

• Severe motor fluctuations

Newest 2025 Advances

Weekly Injection Option:
Recent research has developed once-weekly injections that steadily deliver medication over 7 days. This reduces the need for multiple daily pills.

Adaptive Deep Brain Stimulation:
New systems allow real-time adjustments to brain stimulation based on symptoms, providing better control.

Disease-Slowing Medications:
Researchers are developing medications that may actually slow disease progression, not just manage symptoms.

Beyond Medication: Daily Activities That Help

Research shows that what you do every day is as important as taking medicine.

Physical Exercise

Movement is medicine for Parkinson’s:

Best Activities:

• Tai chi or yoga: Improves balance and flexibility

• Strength training: Maintains muscle and independence

Why exercise helps:

• Improves balance and reduces fall risk

• Keeps muscles flexible

• Improves walking and movement

• Helps mood and sleep

• May slow disease progression

Important: Exercise works best when done regularly and supervised, especially for balance activities.
