Speech Therapy for Adults: Conditions Treated and What to Expect

Many people associate speech therapy primarily with children. In reality, speech-language pathologists work with adults across the lifespan, addressing a wide range of communication and swallowing conditions. If you or someone you love is experiencing a communication difficulty as an adult, speech-language pathology may be part of the answer.

Why Adults Seek Speech Therapy

Adults seek speech-language pathology services for many reasons, including:

• Communication changes following stroke or traumatic brain injury
• Voice disorders affecting professional or daily communication
• Stuttering that has persisted from childhood or emerged in adulthood
• Swallowing difficulties following illness, surgery, or neurological changes
• Communication changes associated with neurological conditions like Parkinson's disease, ALS, or MS
• Accent modification for professional or personal communication goals
• Cognitive-communication difficulties following brain injury or illness

Acquired Communication Disorders

Aphasia — the language disorder that frequently follows stroke — is one of the most common reasons adults seek speech therapy. As discussed elsewhere, aphasia affects the ability to speak, understand, read, and write in varying combinations.

Dysarthria is a motor speech disorder in which the muscles used for speaking are weakened, paralyzed, or uncoordinated. It can result from stroke, traumatic brain injury, Parkinson's disease, ALS, multiple sclerosis, and other neurological conditions. Speech may sound slurred, slow, mumbled, or difficult to understand. Treatment focuses on improving speech clarity and intelligibility through exercises and compensatory strategies.

Apraxia of speech is a motor planning disorder in which the person has difficulty coordinating the precise sequences of muscle movements needed for speech, despite having intact muscles. It typically results from stroke or brain injury. Treatment involves intensive, repetitive practice of sound sequences to rebuild motor plans for speech.

Cognitive-communication disorders involve communication difficulties resulting from underlying cognitive impairments — in attention, memory, reasoning, and problem-solving — rather than language processing specifically. These can follow traumatic brain injury, stroke affecting the right hemisphere, or other neurological events. Treatment addresses the cognitive foundation of communication as well as the communicative behaviors themselves.

Progressive Neurological Conditions

Several progressive neurological conditions affect communication over time, and speech-language pathologists play an important role in managing communication across the arc of these conditions.

Parkinson's disease frequently affects voice and speech. The voice may become soft and breathy, articulation may become less precise, and rate may change. The Lee Silverman Voice Treatment (LSVT LOUD) is a well-researched, intensive treatment specifically designed for voice and speech in Parkinson's disease.

Amyotrophic lateral sclerosis (ALS) progressively affects the muscles of speech and swallowing. Speech-language pathologists work with ALS patients on voice banking (recording the voice for use with speech-generating devices), AAC planning, and swallowing management.

Multiple sclerosis (MS) can affect speech, voice, and language depending on the location and extent of lesions. Symptoms fluctuate and may worsen with fatigue. Treatment addresses the specific profile of difficulties present.

Dementia affects communication in progressive ways across different types and stages. Speech-language pathologists support both the person with dementia and their communication partners, developing strategies to maintain meaningful communication as long as possible.

Voice Disorders in Adults

Voice disorders affect adults across many professions. Teachers, lawyers, clergy, sales professionals, singers, and anyone who uses their voice heavily is at elevated risk. Common voice disorders include vocal nodules, polyps, muscle tension dysphonia, and age-related voice changes. Voice therapy with a speech-language pathologist who specializes in voice is the primary treatment approach.

Swallowing Disorders

Dysphagia — difficulty swallowing — is a condition that speech-language pathologists are uniquely qualified to evaluate and treat. It can occur following stroke, head and neck cancer treatment, neurological disease, or as a result of structural changes from surgery. SLPs conduct swallowing evaluations and develop treatment plans that address both the safety and the efficiency of swallowing.

Accent Modification

Accent modification is not a treatment for a disorder — it is a service for adults who wish to modify their accent for professional or personal communication goals. A speech-language pathologist provides systematic instruction in the sound system of American English. This service is entirely elective and has no bearing on the quality or validity of any accent.

What to Expect in Adult Speech Therapy

Adult speech therapy begins with a comprehensive evaluation to identify the nature and extent of the communication difficulty, establish baseline measures, and develop treatment goals. Sessions are tailored to the individual's specific profile, goals, and daily life context.

Adult clients are active participants in goal-setting. A good speech-language pathologist will discuss your priorities, explain the treatment options and their evidence base, and develop a plan that fits your life.
