The prognosis for speech to return after a stroke can vary from patient to patient.

How does stroke cause difficulty speaking and receptive language problem?

People with stroke can have difficulty with articulation ‘dysarthria’ or difficulty with language ‘aphasia’. While many patients have only dysarthria or aphasia, some can have both speaking problems.

People with aphasia may have trouble in saying phrase or more than one word at a time, choosing the right word to express what they want to say, or even trouble in speaking at all. And for those with dysarthria, they cannot speak properly because a problem has affected the muscles that they use to talk.


Language impairments affect about one-fourth of all cases of stroke, according to the National Institute of Neurological Disorders and Stroke. This problem can include the decreased ability to write, speak, and difficulty in understanding spoken & written language.

Left-side brain is the dominant centers for language. Therefore, people with left-brain damage in stroke are more likely to have more severe speech and language problem.

If you have this kind of aphasia, you may still be able to say more than 1 words or even a sentence at a time, but your interlocutors may still be difficult to understand the words that you say because what you say may not make sense.

And people with fluent aphasia often don’t realize that they are not making sense. And depending on how severe the injury that affects the brain, aphasia due to stroke can be a complex problem.


As mentioned before, dysarthria can occur when there is a problem with the muscles that help you to say a word and talk.

The problem can be a paralysis or weakness of muscles in the throat, neck, mouth, or even weakness of some muscles in the face. And stroke is one of the common causes of dysarthria. Other causes include traumatic brain injury, dementia, and brain tumor.

Dysarthria can cause a decreased voice quality, slurring of words, or labored speech. The weakness of muscles in the face may also cause dropping /drooling of one side of the patient’s face.

Moreover, dysarthria may also cause a problem in moving tongue, lips, or even jaw. Sometime it is also followed with difficulty swallowing or/and difficulty chewing.
