Understanding the Stages of Parkinson’s Disease

Parkinson’s disease (PD) progresses in stages, each presenting unique challenges and opportunities for care. 

When discussing Parkinson’s disease, many people reference the Hoehn and Yahr scale to describe its progression. While this system provides a helpful framework for understanding broad stages of the disease, it has significant limitations. Parkinson’s is a highly individualized condition, and its symptoms, severity, and progression can vary greatly from person to person. The Hoehn and Yahr scale focuses primarily on motor symptoms, overlooking the full spectrum of non-motor symptoms that can significantly impact quality of life. To explore these limitations further, check out our article on biological staging in Parkinson’s. 

As we explore the stages of Parkinson’s here, it’s important to remember that no scale can fully capture the complexity of this disease. By understanding these stages as a general guide rather than an absolute roadmap, we can better appreciate the unique experiences of individuals living with Parkinson’s.

What Are the Stages of Parkinson’s Disease?

Parkinson’s disease is often categorized into five stages, as outlined by the Hoehn and Yahr scale. These stages provide a framework for understanding the progression of motor symptoms, which can range from mild to more advanced and complex. The non-motor symptoms of PD play a significant role in the PD journey but are not captured in the H&Y scale. 

Stage 1: Early-Stage Parkinson’s

• Symptoms:
  • Mild and often unilateral (affecting one side of the body). 
  • These may include slight tremors, stiffness, or changes in posture and facial expression.
• Impact:
  • Symptoms are generally not severe enough to interfere significantly with daily activities.
• Care Focus:
  • Neurological evaluation for diagnosis and treatment planning.
    • Having a list of questions prepared can help make the visit more productive. 
  • Building a care team, including a movement disorders specialist and physical therapist.
  • Initiating regular exercise and adopting a healthy lifestyle to manage symptoms proactively, including smart nutritional choices.
  • Learn more aboutParkinson’s disease symptoms.
  • It is never too early to find a support group. Receiving a diagnosis can be a lot to process and it can help to meet others who have been in your shoes. APDA can help connect you to a group that’s right for you. Find an APDA location, or contact us at apda@apdaparkinson.org for help.

Stage 2: Bilateral Symptoms Develop

• Symptoms:
  • Symptoms become more noticeable and affect both sides of the body. 
  • These may include increased stiffness, slowness of movement (bradykinesia), and slight difficulties with balance.
• Impact:
  • Daily tasks may take longer, but independence is generally maintained.
• Care Focus:
  • Adding occupational therapy to support fine motor skills and enhance independence.
  • Exploring speech therapy if voice or swallowing issues arise.
  • Continuing regular exercise, focusing on balance and strength. Learn more about exercise and Parkinson’s disease. Physical therapy can help maintain integrity and speed of walking. 
  • Care partners need support too, and if they haven’t already, should consider a support group where they can learn from each other, safely share their concerns, and find a sense of community. APDA can help. See available resources for care partners.

Stage 3: Mid-Stage Parkinson’s

• Symptoms:
  • Balance issues become more pronounced, leading to a higher risk of falls.
  • Movements are slower, and activities of daily living require more effort.
• Impact:
  • Greater assistance may be needed, though many people remain independent.
• Care Focus:
  • Consulting with physical therapists specializing in Parkinson’s for fall prevention and mobility.
  • Engaging with a social worker to access community resources and plan for potential future needs.
  • Ensuring medication regimens are optimized for symptom management.

Stage 4: Advanced Symptoms

• Symptoms:
  • Motor symptoms are increased in severity and impair mobility and independence. 
  • Assistance with daily activities is often required.
• Impact:
  • Walking may require aids, and support from caregivers becomes essential.
• Care Focus:
  • Introducing home health aides for daily support.
  • Ensuring mental health support for both the person with PD and their care partners.
  • You may want to consider some home modifications to improve safety and help keep the person with PD at home longer.

Stage 5: Late-Stage Parkinson’s

• Symptoms:
  • Individuals may be confined to a wheelchair or bed and require 24-hour care. 
  • Non-motor symptoms, such as cognitive changes and difficulty swallowing, may dominate.
• Impact:
  • Full dependence on caregivers and healthcare professionals.
• Care Focus:
  • Collaborating with a multidisciplinary team including neuropsychologists, dietitians, and palliative care experts.
  • Addressing nutrition challenges and preventing complications like aspiration pneumonia. Learn about Parkinson’s diet and nutrition.
  • Offering emotional and psychological support to caregivers. Exploreresources for Parkinson’s care partners.
  • APDA’s “Planning for the What-If’s” blog series focused on advanced PD may serve as a helpful resource at this stage.

Factors That Influence Parkinson’s Progression

Parkinson’s disease progression is highly individualized, influenced by a variety of factors beyond what any single scale can capture. From genetic predispositions to environmental triggers, understanding these factors can help provide a more comprehensive view of the disease.

Factors in Parkinson’s Disease Progression

Creating a Support Network for Every Stage

Each stage of Parkinson’s disease calls for a care team that adapts to meet your evolving needs. Key members of this team may include:

• Neurologist or Movement Disorder Specialist: To guide treatment and monitor disease progression.
• Physical, Occupational, and Speech Therapists: To help manage motor and non-motor symptoms.
• Social Workers: To provide resources, emotional support, and guidance.
• Care Partners: As a care partner, you play a vital role in advocacy and daily support. Educating yourself about Parkinson’s is the first step to advocating effectively.
• APDA: Our team is here to help every step of the way.

Additional care team members could also include:

• Medical subspecialists, such as a gastroenterologist or a urologist
• Psychologists and psychiatrists
• Dietitians
• Fitness professionals
• And many other experts who can help and support as the needs change over time

Living with Parkinson’s Disease

Be Proactive in Your Care Journey

Educating yourself and advocating for holistic care can significantly impact your Parkinson’s journey. Speak with your healthcare team about adding specialists as your needs evolve.

For additional resources, connect with APDA’s local Chapters or attend support groups and webinars tailored to Parkinson’s care.

Make APDA Part of Your Healthcare Team

APDA is here to with the support, education, and community to help everyone impacted by PD live life to the fullest. As a part of your healthcare team, we can help you understand more about the disease, help you stay active and engaged though programs and classes, help you build a community of support, refer you to local resources, and much more. We are here for you every step of the way.

Palliative Care and Parkinson’s disease

Palliative care is a medical approach for those with complex illnesses, in which the focus is on maximizing quality of life. This approach can be applied at any stage of the disease, even at the time of diagnosis. Many people with PD have experienced this type of approach from their physicians, often to a limited degree, when a treatment or therapy is added to improve quality of life. 

Because palliative care is a term that people with PD and their care partners may have heard of, but may not fully understand, we looked to further clarify this concept by speaking to an expert on palliative care for PD, Dr. Jori Fleisher. Dr. Fleisher is a movement disorders physician with expertise in palliative care who joined APDA to answer audience questions about how the palliative care approach can benefit people with PD and help improve quality of life throughout the continuum of disease.
