Speech Therapy for Parkinson’s Disease

Parkinson’s disease affects far more than movement. For many people, it gradually impacts speech, facial expression, and swallowing—making it harder to be heard, understood, or enjoy meals comfortably. These symptoms may start subtly but can significantly interfere with quality of life over time.

As a speech-language pathologist, I help adults with Parkinson’s preserve their ability to speak, eat, and engage with the people and activities they love. My therapy approach focuses on early intervention, daily function, and long-term support.

What is Parkinson’s Disease?

Parkinson’s disease is a chronic, progressive neurological disorder that affects how the brain controls movement. It occurs when cells in a part of the brain called the substantia nigra become damaged or die. These cells are responsible for producing dopamine, a chemical messenger that plays a critical role in coordinating smooth and purposeful movement.

As dopamine levels decrease, the brain's ability to regulate movement becomes impaired, leading to a wide range of motor and non-motor symptoms.

Core Motor Symptoms of Parkinson’s Disease

  • Tremor: Often begins in one hand, especially when at rest

  • Bradykinesia: Slowness of movement, making everyday tasks more difficult

  • Rigidity: Muscle stiffness that can limit range of motion

  • Postural instability: Poor balance and increased risk of falls

Common Non-Motor Symptoms

  • Speech and voice changes: Soft, monotone, or slurred speech

  • Swallowing problems (dysphagia): Difficulty chewing or safely swallowing food and liquids

  • Facial masking: Reduced facial expression due to decreased muscle movement

  • Cognitive changes: Memory issues, slowed thinking, or trouble with planning

  • Mood disorders: Depression, anxiety, and apathy are common

  • Sleep disturbances: Insomnia, vivid dreams, or REM sleep behavior disorder

  • Autonomic dysfunction: Issues with blood pressure, digestion, or temperature regulation

Causes and Risk Factors

The exact cause of Parkinson’s is still not fully understood. It’s believed to involve a combination of genetic and environmental factors. Most cases are considered idiopathic (no known cause), but some are linked to inherited gene mutations or exposure to certain toxins.

Parkinson’s typically develops in people over the age of 60, but younger-onset cases do occur.

Is There a Cure?

There is currently no cure for Parkinson’s disease, but a variety of treatments can help manage symptoms and improve quality of life. These include:

  • Medications, such as levodopa, to replace or mimic dopamine

  • Deep brain stimulation (DBS) for advanced cases

  • Physical, occupational, and speech therapy to maintain movement, independence, and communication

How Parkinson’s Affects Speech and Swallowing

Parkinson’s is a progressive neurological disorder that affects the brain’s ability to regulate movement. It commonly impacts speech and swallowing in ways that may include:

  • A voice that becomes soft, hoarse, or monotone

  • Slurred or imprecise speech

  • Reduced facial expression (often called a “masked face”)

  • Difficulty chewing or swallowing safely (dysphagia)

  • Drooling or dry mouth

  • Trouble initiating speech or getting words out smoothly

These symptoms tend to progress over time—but therapy can help slow the decline and improve communication in meaningful ways.

What Therapy Can Help With

Therapy for Parkinson’s is highly specialized. My goal is to help each individual maximize their communication and swallowing abilities for as long as possible. Depending on the stage and specific symptoms, our work may focus on:

  • Voice therapy to increase vocal loudness and clarity

  • Articulation exercises to improve how clearly speech is produced

  • Breathing and pacing strategies to help with vocal projection and sentence flow

  • Facial and oral motor exercises to support expression and muscle control

  • Swallowing strategies to make eating safer and more comfortable

  • Communication tools or cues to support conversation in later stages

For many clients with Parkinson’s, I use techniques drawn from LSVT LOUD®, an evidence-based voice therapy program developed specifically for this population. The approach focuses on speaking with intent and effort to counteract the reduced vocal volume and expression that often accompany Parkinson’s.

When to Begin Therapy

One of the most important things I share with individuals and families is this: don’t wait until speech becomes a major problem. Starting therapy early—even when symptoms are mild—can help maintain function and independence longer. It’s often easier to preserve abilities than to rebuild them after significant decline.

If you’ve noticed that people are asking you to repeat yourself more often, or if your loved one’s voice seems softer or harder to follow, that’s a good time to begin.

Swallowing Support

Many individuals with Parkinson’s experience changes in swallowing that increase the risk of choking, coughing during meals, or even aspiration pneumonia. In therapy, I assess swallowing function and work on strengthening the muscles involved, improving coordination, and introducing strategies to reduce risk—such as posture changes, pacing techniques, and diet adjustments.

My Approach

I work with adults across Palm Beach County, including in-home sessions for those in Boynton Beach, Delray Beach, and surrounding areas. Each therapy plan is tailored to the individual, and I offer caregiver education as well, so families can better support communication and nutrition at home.

Therapy sessions may include:

  • Customized voice and speech exercises

  • Structured home practice routines

  • Ongoing progress monitoring and plan updates

  • Guidance on communication aids, if needed later in the disease

Get the Support You Deserve

If Parkinson’s is beginning to affect your voice, swallowing, or communication, you don’t have to face it alone. Therapy can help you stay connected, stay safe, and stay in control.
