Stroke and Communication Changes


After a stroke, people very frequently experience changes in various areas of communication:

  • verbal expression (finding words and forming sentences)

  • understanding others' speech

  • reading and writing

  • use of gesture and facial expression

  • speech production (speech sounds, rhythm of speech)

  • voice quality

  • cognitive communication (verbal reasoning, verbal memory, attention)

  • stuttering

Below are brief descriptions of communication disorders associated with stroke, assessment and treatment options, and informational resources.


25-40% of stroke survivors will acquire aphasia – a reduction in the ability to express and understand language. People with aphasia may have difficulty with word finding and forming sentences, say things that don’t sound like real words, misunderstand what others say, have difficulty reading and writing, and have problems using gestures.

Cognitive Communication



Cognitive impairment that affects communication may also result following a stroke. Deficits in attention, organizing information, retaining verbal information, and reasoning can have a substantial impact on a person’s daily life, relationships, and functioning.

Motor Speech - Dysarthria and Apraxia of Speech

Many individuals will acquire a motor speech disorder (dysarthria and/or apraxia of speech). About 40% of stroke survivors will exhibit dysarthria – difficulty making speech sounds. It can involve unclear speech, altered vocal quality (e.g., hoarse or breathy), lowered volume, hypernasality, monotone speech, and a rapid or slow rate. Apraxia of speech is difficulty with programming the sequences of movements to produce speech. It often co-occurs with aphasia.

Right Hemisphere Dysfunction

After a stroke, people may have difficulty with attention, visual neglect (impact on reading and writing), reasoning and problem solving, producing and understanding ‘prosodic’ features of language (meaning that is conveyed with changes in stress, rate, rhythm, and intonation), understanding non-literal language (e.g., lies, jokes, sarcasm, idioms), interpreting emotion conveyed verbally and through facial expression, ‘pragmatics’ (communicating appropriately in specific social contexts, such as when speaking with a manager versus a friend), and conversation skills (e.g., maintaining a topic, turn-taking). Such symptoms may not be obvious in brief interactions but can have a substantial impact on social relationships and employment post-stroke.



Assessment serves to diagnose communication disorders (e.g., Broca’s aphasia), evaluate specific strengths and difficulties, inform treatment planning, and to make a prognosis about potential for improvement.


SLPs work with clients and other professionals to offer recommendations for more effective communication, strategies for coping with a communication disorder, and support with advocating for their needs and rights.


​During the first year, people make gains most rapidly with treatment. People many years post-stroke, however, also demonstrate improvement. With treatment, people can achieve improved communication skills in many areas such as:

  • word finding

  • forming sentences

  • speech clarity, rhythm, and rate

  • understanding of spoken language

  • reading and writing

  • use of strategies

  • voice quality

  • verbal reasoning

  • attention and verbal memory

  • conversation

  • activities of daily living (eg. paying bills)

  • social interactions with friends and family

  • community participation

Treatment for aphasia can be provided remotely through telepractice.
