Parkinson’s Disease Stages

Healthcare providers often describe Parkinson’s disease movement symptoms in five stages. These stages range from mild to more advanced later on.

Here’s what each stage of Parkinson’s disease means:

• Stage 1: You have mild symptoms that usually affect only one side of your body. These don’t interfere much with daily activities, and you’re fully independent.
• Stage 2: Symptoms become more noticeable and affect both sides of your body. You can still live on your own, but daily tasks may take longer or feel more tiring.
• Stage 3: This is the middle stage. Symptoms cause mild to moderate disability. You can still be independent, but daily activities may be harder to do because movements are slower.
• Stage 4: Symptoms are severe and limit most activities. You may still be able to stand or walk without help. But you may need significant aid with daily things, like dressing, eating or bathing.
• Stage 5: This is the most advanced stage. You need full-time care and help with all daily activities.

This staging system is known as the Hoehn and Yahr scale. It helps explain how movement and daily activities change over time. It’s important to remember that this scale doesn’t include non-motor symptoms, like thinking or memory changes. Your provider may use other tools to assess these areas.

What symptoms are common during each stage?

Parkinson’s disease affects everyone differently, but certain symptoms are more common at each stage. These examples focus on typical movement changes over time:

• Stage 1: Mild movement symptoms on one side of your body only, like a tremor, along with small changes in posture, walking or facial expression
• Stage 2: Movement symptoms on both sides of your body, like a tremor and stiffness, with more noticeable changes in walking and posture
• Stage 3: Balance problems and slower movements, with a higher risk of falls
• Stage 4: Severe movement symptoms that make tasks harder, often requiring a cane, walker or help from another person
• Stage 5: Severe stiffness and movement limitations make standing or walking very hard, often requiring a wheelchair or bed, along with a higher chance of thinking changes and other non-movement symptoms

Symptoms and progression can vary. Your healthcare provider can explain what to expect in your situation.

What happens in late-stage Parkinson’s

Late-stage Parkinson’s disease refers to advanced stages (stage 4 and stage 5). At this point, symptoms are more severe and usually affect most parts of daily life. You may need a lot of help from others.

You can expect movement to be much harder. You may have severe stiffness and slowness. This can make standing or walking unsafe or impossible without help. Balance problems are common, and falls can happen more easily.

Talking, chewing and swallowing can also be difficult. Swallowing problems raise the risk of food or liquid going into your airway. This may lead to serious health issues.

Late-stage often includes non-movement symptoms, too. Memory can further decline, and depression and anxiety can worsen.

Some people develop Parkinson’s-related dementia. This can affect attention, planning and your ability to manage daily tasks. The exact timing of dementia symptoms varies, but they usually appear in the mid- to late stages.

Because symptoms can be complex, planning for safety, daily support and medical care is very important for both you and your family.

How long do stages last?

Parkinson’s disease moves at different speeds for different people. Healthcare providers can’t predict how long you’ll stay in any one stage. Many people remain in the early or middle stages for years, and sometimes even decades.

Remember, Parkinson’s disease doesn’t follow a set timeline. Progression can vary widely from one person to the next. How quickly your symptoms changed in the past is the best guide to what may happen next.

How can you tell which stage someone is in?

Your provider assigns the stage based mostly on movement changes and how much they affect your daily life. They’ll look for:

• Balance and risk of falling
• How independent you are with daily activities, like dressing, bathing and eating
• Walking ability and posture
• Which side of your body symptoms affect (one side or both)

Parkinson’s affects everyone differently, so stage labels don’t always match how hard daily life feels. If you notice new or worsening symptoms, whether movement-related or not, let your provider know so they can adjust your care.

How can I prepare for each stage of Parkinson’s disease?

Thinking about how Parkinson’s disease can change over time may be challenging, especially when you read about symptoms you don’t have yet. Still, understanding what may happen next might help you plan ahead, stay safer and feel more prepared.

Focusing on a few key areas could help:

• Work closely with your care team. Medicines and other treatments help manage symptoms. Your treatment plan may change over time with your needs.
• Build healthy routines you can stick with. Staying active, eating well and getting enough rest are things you can manage. These habits support your overall well-being as the condition progresses.
• Plan for safety and daily changes. As symptoms increase, tasks like walking, talking or dressing may get harder. Planning ahead for tools or support may make daily life easier and safer. You may need to consider help at home or changes to your living space if independence becomes harder.
• Keep open conversations with loved ones. Talking regularly with the people who support you can help everyone understand what you need now and what you may want later.

Are there other tools used to assess Parkinson’s disease?

Parkinson’s disease is often described using stages. But providers also use other tools that look at symptoms in more detail. These scales don’t label your condition by stage. Instead, they help your provider understand how Parkinson’s disease is affecting you right now and track changes over time. You may hear these mentioned during diagnosis or follow-up visits.

Unified Parkinson’s Disease Rating Scale

The Unified Parkinson’s Disease Rating Scale (UPDRS) is another tool your provider may use to measure how severe movement symptoms are right now. Many providers use an updated version called the MDS-UPDRS.

It includes a series of short tests that look at how the disease affects movement and nerve function. During the exam, your provider may check:

• Balance
• Facial expressions
• How quickly your arms and legs move
• Muscle stiffness
• Speech
• Tremor

Each area receives a score. The total score shows how Parkinson’s symptoms are affecting you at that time.

Unlike the Hoehn and Yahr scale, the UPDRS doesn’t place Parkinson’s disease into stages and can’t predict what will happen next. Scores may change from day to day or with medication adjustments.

Parkinson’s Disease-Cognitive Rating Scale

The Parkinson’s Disease-Cognitive Rating Scale (PD-CRS) is a short test that providers use to check changes in thinking and memory. It looks at skills like:

• Attention
• Memory
• Planning
• Problem-solving
• Word-finding

These skills may change even in the early stages of the condition.

Even though it’s a test, you don’t need to study. Your provider will ask you to do simple tasks. These may include remembering words, naming objects, drawing or saying words that follow certain rules. Each task receives a score. The scores are added together to show how well your brain is working.

You may see your total score or be told whether your results fall in a range. This scale helps providers spot and track changes in thinking and tell the difference between normal thinking, mild cognitive changes or dementia in Parkinson’s disease. But you won’t be given a stage number. This instead helps them track changes over time and plan care.
