Motivation in Parkinson’s: Dopamine, Apathy, and INTENT

One of the most overlooked challenges in Parkinson’s disease is a lack of motivation or apathy. Families may notice that people with Parkinson’s struggle to start activities or follow through with exercise. People with Parkinson’s are not lazy. This lack of motivation is not a matter of willpower but a direct result of changes in the brain’s chemistry. The SPEAK OUT!® Therapy Program serves as an antidote to apathy, reigniting purpose and engagement in individuals with Parkinson’s by empowering their voice.  

Dopamine’s Role in Motivation

Dopamine is a neurotransmitter that carries messages between nerve cells. Not only is it responsible for the planning and execution of automatic movements, it also is responsible for motivation and drive. A decrease of dopamine, as found in people with Parkinson’s, can present as apathy. It interferes with the effective management of PD symptoms, since apathetic people are less inclined to exercise and follow their medication schedules.  

Apathy vs. Depression

Up to 40% of people  with Parkinson’s experience apathy. It is not the same as depression. Depression involves sadness, hopelessness, or loss of pleasure, while apathy is a lack of initiative and reduced effort. Someone with apathy may not feel sad, but they struggle to start even simple daily tasks. Recognizing this difference is crucial because it shapes how families and clinicians respond. Apathy should not be mistaken for disinterest or laziness; it is a neurological symptom tied to dopamine loss.

How Low Motivation Appears in Daily Life

For people with Parkinson’s, low motivation can affect every part of daily living. Common examples include:

  • Avoiding exercise even when the benefits are understood
  • Delayed participation in therapy or home exercise programs without reminders
  • Reduced interest in meals, hobbies, or social activities that used to be enjoyed
  • Hesitation to attend group events or therapy sessions

Care Partners often describe these behaviors as puzzling or frustrating, especially when the person acknowledges the importance of staying active but struggles to act on it. Understanding that the root cause is biological can shift the response from frustration to empathy, and from blame to support.

The Science of Speaking with INTENT

Loss of dopamine disrupts the brain’s automatic motor system, which typically manages walking, talking, and swallowing without conscious effort. This is why everyday activities may feel difficult or inconsistent for people with Parkinson’s.

The intentional motor system, however, remains available. By focusing deliberately, people can bypass impaired automatic pathways. SPEAK OUT! Therapy teaches people with Parkinson’s to speak with INTENT, which means to project the voice or to speak with purpose. This approach shifts speaking from an automatic function to an intentional act.

The Circle of INTENT

The SPEAK OUT! Therapy Program is illustrated by the Circle of INTENT.  

  • SPEAK OUT! Evaluation – An evaluation is conducted by a Certified SPEAK OUT! Provider. This is a speech-language pathologist who has completed specialized training through Parkinson Voice Project.
  • SPEAK OUT! Booklet & Flashcards – Parkinson Voice Project provides a digital SPEAK OUT! Booklet & Flashcards to every patient enrolled in the SPEAK OUT! Therapy Program.  
  • What is Parkinson’s? Video – Patients, families, and close friends watch this video to learn about Parkinson’s and to understand why “INTENT” is an important key to managing this disease. 
  • Individual SPEAK OUT! Therapy – Patients and families work with a Certified SPEAK OUT! Provider to learn the SPEAK OUT! Exercises and establish a consistent home practice routine.
  • SPEAK OUT! Therapy Groups – Weekly SPEAK OUT! Therapy Groups are essential for ongoing speech practice, education, and support. They also foster accountability, reduce isolation, and build camaraderie with other SPEAK OUT! Graduates.
  • SPEAK OUT! Refreshers – Patients and families meet with their Certified SPEAK OUT! Provider every 6-12 months for a re-evaluation to ensure that progress is maintained and that a consistent home practice routine continues.
  • Daily SPEAK OUT! Home Practice –  Daily practice is essential to regaining and retaining speech and swallowing. Parkinson Voice Project provides free SPEAK OUT! Therapy practice sessions online and access to a digital SPEAK OUT! Booklet and flashcards. A SPEAK OUT! Booklet is mailed to each patient working with a Certified SPEAK OUT! Provider in the US.

The Circle of INTENT conveys that Parkinson Voice Project is with people with Parkinson’s for the long haul. The SPEAK OUT! Therapy Program never stops. 

Community and Care Partner Support

Motivation grows stronger with shared experiences. SPEAK OUT! Therapy Groups ensure that participants are practicing alongside others who have the same challenges and goals. This component of the program turns therapy into a community effort, which is especially powerful for combating apathy.

Care Partners play a vital role. Simple reminders, shared participation in practice, and encouragement to attend group sessions all help sustain progress. Recognizing that motivation lapses are neurological symptoms, not personality flaws, enables Care Partners to respond with patience and empathy.

Parkinson Voice Project also offers a Parkinson’s Family Education Group, to provide Care Partners and families with education, resources and a supportive community. These monthly sessions provide practical tools to navigate the Parkinson’s journey. 

Research and Long-Term Outcomes

Families often notice that confidence returns, phone calls feel easier, and social outings are more enjoyable. These lived experiences are reflected in Parkinson Voice Project’s research, which highlights measurable improvements in vocal volume, clarity, and social participation. Most importantly, SPEAK OUT! Refreshers, a critical component of the SPEAK OUT! Therapy Program, ensure that progress is maintained for the long haul.

FAQ’s

Why do people with Parkinson’s struggle with motivation?
Motivation challenges in Parkinson’s are a result of dopamine loss, not a lack of effort. Addressing them requires structured support that combines education, practice, and community. The SPEAK OUT!

We help people with Parkinson’s REGAIN and RETAIN their speech and swallowing, replacing apathy with purpose and engagement.
Is apathy the same as depression?
No. Depression involves sadness and loss of pleasure, while apathy is a lack of initiative and reduced effort without sadness. Both can occur in Parkinson’s, but apathy is specifically linked to dopamine changes. As with all new symptoms, consult your movement disorder specialist.
How does motivation affect a patient’s participation in the SPEAK OUT! Therapy Program?
People with Parkinson’s may understand that daily SPEAK OUT! Home Practice is essential to retain their speech and swallowing; however, they find it difficult to maintain the daily practice consistent habit. The SPEAK OUT! Therapy Program provides accountability and therapeutic support to keep progress going even when internal motivation is low.
What is speaking and swallowing with INTENT?
Speaking with INTENT means projecting the voice with deliberate effort. Swallowing with INTENT means focusing, and ensuring each swallow is complete and safe. This approach bypasses weakened automatic pathways and builds confidence.
What role do Care Partners play?
Care Partners provide reminders, encouragement, and shared participation in practice. Understanding that lapses in motivation are symptoms of Parkinson’s helps Care Partners respond with empathy instead of frustration.
Can motivation improve over time with therapy?
Yes. While dopamine loss makes motivation difficult, structured support systems like SPEAK OUT! Therapy, SPEAK OUT! Therapy Groups, and SPEAK OUT! Refreshers can help people with Parkinson’s REGAIN and RETAIN their speech and swallowing for the long term.
