About Parkinson’s Disease

We are here to come alongside you on your journey.

At the Indiana Parkinson Foundation, we know that a Parkinson’s diagnosis can feel overwhelming—but it does not have to be isolating. Whether you are newly diagnosed, have been living with Parkinson’s for years, or are a family member or caregiver, we are here to come alongside you on this journey.

What Is Parkinson’s?

Parkinson’s disease is a progressive neurological condition that affects movement, mood, and more. It occurs when nerve cells in the brain that produce dopamine—a chemical that helps control movement—are damaged or die, leading to a dopamine deficiency and difficulty with movement control. Parkinson’s is most diagnosed after age 60, it can also affect younger individuals.

Causes of Parkinson’s Disease

While the exact cause of PD is unknown, most experts agree that the condition is caused by a combination of genetic and environmental factors (chemicals, viruses, injuries). It is known that exposure to certain environmental factors increases an individual’s risk of developing PD, but exposure to any one of these factors does not mean a person will develop the disease. Other non -genetic risk factors include insecticides, herbicides, Agent Orange, and a synthetic neurotoxin called MPTP.

Common Symptoms

Parkinson’s affects everyone differently. Symptoms can be both physical (motor symptoms) and non-physical (non-motor), and they can change over time.

Early Detection and Diagnosis

Early Detection and diagnosis are crucial for potentially slowing the progression of Parkinson’s. Early detection can also be a key to improving quality of life as well. 

Parkinson’s can start with subtle signs like:

There is no single test for Parkinson’s—diagnosis is usually based on a neurologist’s evaluation and supportive tests. For example, a skin biopsy can be a helpful tool in diagnosing PD.  The test detects an abnormal form of alpha-synuclein, a protein that clumps together in the brains of individuals with Parkinson’s. While it is not a standalone diagnostic tool, it can be a valuable addition to the neurologist’s assessment, especially when symptoms are unclear.

A neurologist will make a diagnosis based on the following:

If you or someone you love is noticing changes, early medical attention can make a significant difference.

Understanding the Stages of Parkinson’s

Every journey with Parkinson’s is different. While doctors often describe the condition in stages, it’s important to remember that symptoms progress differently for each person. Support and education can make a meaningful difference at every stage.

Stage One

Symptoms are usually mild and may not disrupt one’s activities of daily life. Tremors or movement changes may appear on one side of the body, along with subtle shifts in posture or facial expressions.

Stage Two

Symptoms begin to affect both sides of the body. Walking and posture may change, and daily tasks can take a little longer or be more difficult— but most people remain independent.

Stage Three

This is often considered the “middle stage.” Balance may be more challenging, and falls can happen. Everyday activities, like dressing or eating, may take more effort, but many people continue to live active, fulfilling lives with the right resources and support.

Stage Four

Symptoms become more noticeable, and a walker or other mobility aid may be helpful. Assistance with daily activities is often needed — but with care and encouragement, quality of life can still be maintained.

Stage Five

The most advanced stage, when stiffness and mobility challenges may require a wheelchair or full-time care. Non-motor symptoms, such as hallucinations, may also appear. With comprehensive support, comfort and dignity remain the focus.

Treatment Options

While there is no cure for Parkinson’s yet, there are many effective treatments that can help manage symptoms and improve quality of life.

Medications

Living Well with Parkinson’s

Living well is not only possible, but also powerful. Regular exercise, good nutrition, purposeful routines, and social connection all contribute to a higher quality of life. Our programs, like The CLIMB, Support Groups and Educational Programs are designed to support you physically, mentally, and spiritually. Remember, Parkinson’s does not define you—you are still you!

Support for Caregivers and Families

Parkinson’s impacts the whole family. That is why we offer resources and support for not only the diagnosed person, but also caregivers, and the entire family. Whether you are helping with daily tasks, managing medications, or just needing someone to talk to, we are here for you. You do not have to do this alone, and no one should!

Support changes everything. Join us and find a welcoming place to connect, grow, and find encouragement through connection!

Young Onset Parkinson’s (YOPD)

When Parkinson’s appears before age 50, it is called Young Onset. While many of the symptoms are the same, there are unique challenges—careers, parenting, long-term planning. We provide guidance and connection with the resources you need as well.

Hope for the Future

Researchers are learning more about Parkinson’s and moving closer to breakthroughs in treatment and prevention every day. We will stay informed, connected, and hopeful—and we invite you to be part of the journey.
