Speech & language therapy
Also called: SLT, speech pathology, speech-language pathology, aphasia therapy
What speech and language therapy is, the strong evidence behind it for aphasia and communication after stroke, and how to make daily practice count.
Strong evidence it improves communication after stroke. It is the core treatment for aphasia - and the amount and consistency of meaningful practice matter.
Consistent evidence from randomised trials / systematic reviews that it helps.
Speech and language therapy (SLT) helps people rebuild communication after a stroke or brain injury - understanding, speaking, reading, writing, and everyday conversation. It is delivered by a qualified speech-language therapist (also called a speech-language pathologist).
| Area | What it means | Everyday example |
|---|---|---|
| Understanding | Taking in what others say | Following a conversation |
| Speaking | Finding and saying words | Naming a photo |
| Reading | Making sense of text | Reading a menu |
| Writing | Getting words down | Sending a message |
What the evidence says
This is one of the best-supported therapies on this site. A large Cochrane review pooling many randomised trials found that SLT improves functional communication, reading, writing, and expressive language after stroke compared with no therapy [Brady MC 2016] . The same review found that higher-intensity therapy can produce bigger gains, though very intensive schedules led more people to drop out - so practice has to be sustainable, not just heavy.
No single “brand” of therapy was clearly better than another [Brady MC 2016] . What matters most is the amount and consistency of meaningful practice - much of which can happen between sessions through conversation, home activities, and apps.
Where it helps
- Aphasia - trouble with words, understanding, reading, or writing after a stroke [National Institute on Deafness and Other Communication Disorders (NIDCD) 2024] .
- Word-finding (anomia) - structured techniques such as semantic feature analysis can improve naming [Efstratiadou EA 2018] .
- Speech clarity - dysarthria and apraxia of speech.
- Voice - including the LSVT LOUD approach in Parkinson’s.
- Swallowing (dysphagia) - assessment and safer-swallowing strategies.
Honest limits
- SLT does not “cure” aphasia; it builds function and strategies, often over months.
- Progress varies a lot between people, and plateaus are normal.
- Add-on brain stimulation such as rTMS shows promise as a complement to SLT for aphasia, but SLT remains the foundation [Lefaucheur J-P 2020] .
How this site helps
The activities and quizzes below give structured, repeatable practice for naming, sounds, reading, and conversation - a complement to therapy, not a replacement. Explore the guides and research for the detail behind each technique.
