Parkinson’s Disease: Stages, Symptoms, & Treatment

Parkinson’s Disease: Stages, Symptoms, & Treatment

Apr. 11th, 2022

Parkinson’s disease is a common health condition that affects more than 10 million people worldwide.1

Most people are diagnosed with Parkinson’s as an older adult, with 70 years old being the average age for diagnosis. Men are also more likely to develop Parkinson’s than women.2

In honor of Parkinson’s Awareness Month, we’ve shared the stages of Parkinson’s and how it progresses, as well as the symptoms and treatment options.

What is Parkinson’s Disease?

Parkinson’s disease is a neurological movement disorder. This disease affects the nervous system and inhibits the body’s ability to control movement.3

Parkinson’s affects the brain’s dopamine-producing neurons. With this disease, the nerve cells begin to break down or die. When an individual’s dopamine levels start to decrease, it causes an imbalance or abnormal brain activity.4

The exact cause of Parkinson’s is unknown, but it is believed that genes and environmental factors play a role in individuals who develop it. Having a family member that has Parkinson’s can also increase an individual’s chances of being diagnosed with the disease.

Some gene variations are linked to an increased risk of Parkinson’s disease. Scientists have also found certain genetic mutations that can cause Parkinson’s disease, although it’s rare.5

Stages of Parkinson’s

Parkinson’s disease will affect each individual differently. However, there are some common stages of Parkinson’s that people experience as the disease progresses.6

Parkinson’s diseases can affect the quality of life for those who have it. Although in the beginning stages, people may still have a sense of independence, dementia or physical disability is common as it progresses.7

Stage 1

During this first stage, people tend to have mild symptoms that might not even be noticeable. Some symptoms to be on the lookout for include tremors or other movement symptoms occurring on one side of the body. Changes in posture, walking, or facial expressions may also be present.

Stage 2

Stage two is when individuals begin to see symptoms progressing. Tremors typically start to worsen during this stage, and they can occur on both sides of the body. This stage may make daily activities harder.

Stage 3

This is considered the “mid-stage” for Parkinson’s. Loss of balance and slow movements are indicators of stage three. Individuals can still be independent during this stage, but daily activities may be harder and falls are more common.8

Stage 4

Stage four is accompanied by severe symptoms. Individuals need help with standing and walking, and should not be living alone.

Stage 5

Stage five is the most advanced stage of Parkinson’s. In this stage, a person’s legs may be too stiff to stand, and many people require a wheelchair or are bedridden.

Care is needed for all activities during this stage. Individuals in stage 5 may even experience other symptoms, such as hallucinations. 

Symptoms of Parkinson’s

Symptoms of Parkinson’s disease are typically separated into different categories: motor symptoms and non-motor symptoms.7  

Individuals with Parkinson’s disease may not experience all symptoms associated with the disease. There’s no prediction as to how fast the symptoms will progress or worsen.

Primary Motor Symptoms

There are a few different primary motor symptoms that come with Parkinson’s:

  • Resting tremor. This is when one part of the body shakes when it’s not being used. For example, a hand or foot may shake when you’re not using it or are at rest.
  • Freezing of gait. This occurs when someone attempts to take a step forward, but feels as if they are stuck and cannot move.
  • “Mask” face. Facial expressions may look flat as facial muscles lose some of their movement.9

Secondary Motor Symptoms

Some of the secondary motor symptoms associated with Parkinson’s include:

  • Changes in speech
  • Stooped posture
  • Difficulty with hand and finger movements, such as writing
  • Difficulty swallowing
  • Restless movement, such as being fidgety10

Non-motor Symptoms

Non-motor symptoms are not always what people would associate with being a sign of Parkinson’s, as they are present alongside many other health conditions.11 Some common non-motor symptoms that accompany this disease include:

  • Weakened sense of smell or taste
  • Sleep disorders
  • Mood disorders
  • Dizziness
  • Gastrointestinal problems such as nausea or loss of appetite

Early Signs of Parkinson’s Disease

If you’re wondering if you or a loved one might be in the early stages of this progressive disease, here are some early signs to look out for.12

  • Tremor. Have you noticed a shake in a finger or the hand when it’s at rest?
  • Small handwriting. Has there been a change in handwriting? If someone’s writing gets smaller, it could be a sign of Parkinson’s. This is called micrographia.13
  • Loss of smell. Has the sense of smell declined? Is there difficulty smelling foods such as bananas?
  • Trouble sleeping. Do you notice sudden movements during sleep or have difficulty sleeping at night?
  • Trouble moving. Is there a stiff feeling in the legs and arms?

If you or a loved one experience any of these symptoms, contact a medical professional to seek help and receive a proper diagnosis.

Treatment for Parkinson’s

There is currently no cure for Parkinson’s disease. However, there are numerous treatment options available depending on the individual, symptoms, and doctor’s recommendations.

Some of the treatment options for those with Parkinson’s disease include:

  • Lifestyle modifications. This could look like getting more rest or exercise. Exercise helps those with Parkinson’s maintain balance and mobility.
  • Medication. Medication will depend on the person, symptoms, and other existing health issues. Medication can help manage the symptoms, but cannot reverse them.
  • Rehabilitation. Physical and occupational therapy are common forms of treatment for those with Parkinson’s. Moving around, staying active, and performing daily activities on their own are some of the most important goals of those with this disease.
  • Surgery. The two most common procedures for those with Parkinson’s are a deep brain stimulation (DBS) or a surgery to insert a tube into the small intestine that delivers levodopa, a medication for Parkinson’s.14
