Early Parkinson’s symptoms typically develop gradually, taking years before they affect daily life. However, the progression of Parkinson’s can vary from person to person.

Parkinson’s disease is a neurological condition that causes body tremors, slowed movement, difficulties with balance, and muscle stiffness. The progression of this disease can vary widely among individuals, but it is often slow.

Although Parkinson’s can have an adverse effect on quality of life, it does not significantly shorten life expectancy. Regardless of how quickly symptoms progress, many individuals with the condition can lead full and active lives with the right support.

In this article, we will examine some common symptoms of Parkinson’s disease and how quickly they can progress.

It is very difficult to predict the exact progression of Parkinson’s disease. The type of symptoms and the rate at which they progress differ among those living with the condition.

Typically, though, the symptoms of Parkinson’s disease begin slowly and progress gradually. For many people, the condition can take years to progress to a point where it begins to affect daily life. A person with Parkinson’s disease may experience mild or moderate symptoms for decades.

Early symptoms may be subtle, such as:

  • mild tremors
  • speaking more softly than intended
  • fewer facial expressions
  • changes in handwriting
  • changes in how a person moves or walks
  • difficulty getting out of chairs

These symptoms typically begin on one side of the body. Over time, they worsen and begin to affect both sides. Eventually, the symptoms may make speaking, walking, or completing household chores difficult.

Some people may find that symptoms progress quickly, while for others, symptoms may develop slowly and never become severe enough to affect daily life.

The results of a 2022 study suggest that individuals who are older when they develop Parkinson’s disease may experience quicker disease progression.

The symptoms of Parkinson’s disease typically fall into two categories: motor symptoms and nonmotor symptoms.

Motor symptoms

The motor symptoms of Parkinson’s disease affect the way people move. Some of the motor symptoms include:

  • a delay in starting movements and slow movements
  • shaking and tremors at rest that usually go away with movement
  • slow walking or a rapid shuffling with small steps when walking
  • muscle spasms
  • balance problems
  • muscle cramps

In the early stages of Parkinson’s disease, individuals may experience mild motor symptoms, such as tremors or changes in gait, which is how a person walks.

As the disease progresses, these symptoms can make it difficult to complete certain daily tasks. In addition to causing difficulty walking, these symptoms may interfere with speaking, talking, or swallowing.

Nonmotor symptoms

Nonmotor symptoms do not affect movement but can still affect quality of life. Some of these symptoms might develop before motor symptoms. These include:

  • reduced sense of smell or taste
  • sleep disturbances
  • behavior changes
  • digestive symptoms or constipation
  • fatigue
  • a sudden drop in blood pressure when a person stands up
  • dry skin
  • flat facial expressions
  • reduced emotional feelings
  • small handwriting

A person may also develop mental health conditions such as anxiety and depression. In advanced cases, cognitive function may decline, and dementia can develop.

Throughout Parkinson’s disease, levels of the brain chemical dopamine decrease. This decrease leads to the motor symptoms associated with this condition. The most common medication for Parkinson’s disease is levodopa. Nerve cells use this medication to help replenish dopamine levels.

There are also other types of medication for Parkinson’s available. A doctor may recommend taking multiple types to help manage the condition.

People with Parkinson’s disease may also benefit from deep brain stimulation. For this treatment, surgeons implant electrodes into the brain. They can then deliver electrical impulses directly to targeted areas of the brain. This procedure may help reduce or stop motor symptoms.

There are also noninvasive options that can help reduce the symptoms of Parkinson’s disease. These may include:

Life expectancy for people with Parkinson’s disease is similar to that of the general population.

A 2020 study found that people with Parkinson’s disease had a life expectancy that was only 1.2 years shorter than that of individuals without the condition.

Minor changes in life expectancy are most likely to occur in people who receive a diagnosis before the age of 70 years. However, most people living with Parkinson’s disease will experience a typical life span.

People with symptoms that could be Parkinson’s disease should visit a medical professional for a diagnosis.

Several conditions could cause symptoms such as tremors, so it is important that a doctor investigates the cause so that a person can get the right treatment.

Other symptoms, such as issues with balance or excessive fatigue, may also indicate the presence of Parkinson’s disease. Anyone experiencing new or worsening symptoms should contact a doctor for a full evaluation.

Some frequently asked questions about Parkinson’s disease progression include:

Parkinson’s disease symptoms usually develop gradually, and typically, the rate of progression remains stable over time. This means that if a person had a slow progression of symptoms to begin with, this will usually continue.

However, some people can deteriorate more quickly. This could occur if there has been a complication. For example, a stroke could affect movement and balance.

People with Parkinson’s who suddenly get worse should receive medical attention.

Worsening tremors, posture, and walking difficulties are all signs of disease progression. Balance problems leading to falls also indicate that the disease is advancing. Keeping track of Parkinson’s disease symptoms can help with noting progression.

Parkinson’s disease is a neurological condition that can cause tremors, balance problems, slow movements, and muscle stiffness.

The timeline for disease progression varies among individuals. Most people may experience gradual progression over decades, while others may experience rapid disease progression. Typically, though, the progression is slow.

Medical treatments and certain lifestyle changes can help manage disease progression. Individuals living with Parkinson’s disease should discuss management options with their doctor.
