The Role of Speech Therapy in Functional Neurological Disorder (FND) How Speech-Language Pathology Supports Communication, Swallowing, and Cognitive Function

Functional Neurological Disorder (FND) can affect many parts of the body, including the systems responsible for speech, voice, swallowing, and thinking. For many individuals, changes in communication or cognitive skills can be some of the most distressing symptoms, especially when they come and go or worsen with stress and fatigue.

Speech-language pathologists (SLPs) play a key role in FND rehabilitation by helping individuals retrain communication and thinking skills, reduce symptom severity, and regain confidence in daily life. Speech therapy for FND is practical, supportive, and focused on helping people communicate and function more comfortably.

How FND Can Affect Speech and Communication

In FND, the brain has difficulty sending clear signals to the muscles and systems involved in speech and language even though there is no structural damage. This can lead to a variety of communication-related symptoms, including:

• Slurred or unclear speech

• Stuttering or speech blocks

• Voice changes (hoarse, strained, or weak voice)

• Difficulty getting words out

• Sudden loss of voice

• Trouble organizing thoughts or expressing ideas

• Cognitive “brain fog”

These symptoms are real and can significantly impact work, relationships, and self-confidence.

What Does Speech Therapy for FND Look Like?

Speech therapy for FND focuses on retraining normal patterns rather than strengthening damaged structures. Therapy is tailored to each person’s symptoms, goals, and daily communication needs.

An SLP may focus on:

• Education about FND and how it affects communication

• Reducing fear and frustration around symptoms

• Practicing automatic, natural speech patterns

• Using strategies that promote ease and efficiency

• Building confidence in everyday communication situations

Sessions are often functional—working on real-life tasks like conversations, phone calls, presentations, or social interactions.

Treating Speech and Voice Symptoms

Speech and voice symptoms in FND often improve when the nervous system is calmer and speech is produced automatically rather than forcefully.

SLPs may use:

• Gentle voice techniques to reduce strain

• Breath support and relaxation strategies

• Rhythm and pacing techniques

• Distraction or external focus to promote natural speech

• Gradual exposure to challenging speaking situations

Rather than focusing on “trying harder,” therapy helps patients find ease and flow in speech.

Addressing Stuttering and Speech Blocks

Some individuals with FND experience sudden stuttering or difficulty starting speech. Speech therapy helps reduce these symptoms by:

• Identifying triggers such as stress or fatigue

• Practicing speech in low-pressure situations

• Using rhythmic speech, singing, or automatic phrases

• Shifting attention away from the act of speaking

• Building confidence in communication

Over time, these strategies help the brain relearn smoother speech patterns.

Cognitive-Communication Support

FND can also affect thinking skills, such as attention, memory, and processing speed. These changes may make it harder to follow conversations, multitask, or express thoughts clearly.

SLPs help with:

• Improving attention and focus

• Organizing thoughts and ideas

• Word-finding strategies

• Memory supports (lists, reminders, routines)

• Managing mental fatigue

Therapy focuses on practical strategies that can be used at home, work, or school.

Swallowing and Throat Symptoms

Some people with FND experience difficulty swallowing, throat tightness, or the sensation of a lump in the throat. While these symptoms can be frightening, speech therapy can help by:

• Teaching relaxation and breathing techniques

• Addressing muscle tension in the throat

• Improving coordination of swallowing

• Reducing fear around eating and drinking

SLPs work closely with medical providers to ensure swallowing safety and comfort.

Managing Triggers and Nervous System Regulation

Speech symptoms in FND often worsen with stress, anxiety, fatigue, or sensory overload. SLPs help patients recognize these triggers and develop tools to manage them.

Strategies may include:

• Pacing communication throughout the day

• Taking breaks before symptoms increase

• Using grounding or calming techniques

• Practicing communication in manageable steps

These skills support long-term success and independence.

Part of a Team-Based Approach

Speech therapy is most effective when it’s part of a multidisciplinary approach. SLPs work closely with physical therapists, occupational therapists, mental health providers, and physicians to support the whole person—not just one symptom.

A Message of Hope

Communication changes in FND can feel isolating and discouraging—but they are also treatable. With education, practice, and the right support, many people experience significant improvement in speech, voice, and cognitive skills.

Speech therapy for FND is about more than talking—it’s about restoring confidence, connection, and quality of life.

You deserve to be heard, understood, and supported on your path to recovery.
