Apraxia of speech after a stroke: what it is and how families can help

After a stroke, families often hear three words that sound alike and mean different things: aphasia, apraxia and dysarthria. Each changes speech in its own way, and each calls for a different kind of help. This guide is about apraxia of speech, the one families tend to understand least, and it is general information: a speech-language pathologist is the person who assesses which of these is present.

What apraxia of speech is

The National Institute on Deafness and Other Communication Disorders explains that acquired apraxia of speech involves the loss or impairment of existing speech abilities and may result from a stroke, head injury, tumor or other illness affecting the brain. The brain has trouble planning and sequencing the movements of the lips, tongue and jaw that make speech. The muscles themselves are not weak, and the person knows the word. The plan for saying it is what breaks down.

The NIDCD describes the signs: distorted sounds, especially vowels; errors that are inconsistent, so a word comes out right one time and wrong the next; groping for sounds before getting them right; and changes in rhythm, like equal stress on every syllable or pauses in odd places. To a family, it can look like the person is struggling to start, trying again and again, and getting more frustrated with every try.

Apraxia, aphasia and dysarthria

• Aphasia is a language condition. Finding, understanding, reading or writing words can be affected. Our guide to what aphasia is and what it isn't explains it.
• Apraxia of speech is a planning condition. The language is there; the sequence of mouth movements is not reliable.
• Dysarthria is a muscle condition. Weak, slow or uncoordinated muscles make speech slurred, quiet or strained.

The NIDCD notes that apraxia of speech often occurs alongside aphasia, so a person may have both. That matters for the family, because it changes which workarounds help. If language is intact, writing or typing may work well. If aphasia is also present, pictures, gestures and ready-made phrases may work better. The speech-language pathologist can say which is which.

What therapy looks like

The NIDCD says some people recover speech on their own, and for others speech-language therapy is necessary. Therapy is individual and may include intensive one-on-one sessions, often with a lot of repetition of sounds, syllables and words, watching the therapist's mouth, and slowing speech down. It may also include other ways to communicate, such as a device or gestures, while speech recovers. Ask the rehab team how often therapy is planned and what the family can practice at home.

How families can help

• Slow down and wait. Pressure makes planning harder. Silence is not a problem to fix.
• Don't ask for a word on demand. Just say it tends to make things worse; automatic phrases often come more easily than requested ones.
• Let the person see your face when you talk, especially if the therapist uses watching the mouth as a cue.
• Don't correct every error. Respond to the message, not the pronunciation, unless you are in a practice session the therapist set up.
• Ask yes and no questions when a long answer is hard, and accept pointing, gestures, writing and a communication app as real answers.
• Keep practice short and stop when the person is tired. Frustration is information, not failure.

The first weeks: set up a system

Early on, before therapy has had time to help, communication can break down several times an hour. A little structure prevents most of it. Agree on one clear yes and one clear no, a thumbs up and a head shake or a tap on the left or right hand, and tell everyone who visits. Keep a short list of the things the person asks for most (water, the bathroom, the blinds, pain, the phone) somewhere they can point to. When a message will not come, try the question the other way round: is it about you or about someone else? Is it about now or later? Narrowing the topic is faster than guessing words.

Tell visitors what apraxia is in one sentence, so they do not mistake effort for confusion: the words are there, the mouth is having trouble with the plan, give time. A card by the bed with that sentence saves the family repeating it at every visit.

A voice that doesn't depend on the mouth

Because apraxia is about the mouth's plan, a tapped phrase can get a message out when saying it cannot. ExpressAgain's tap-to-speak speaks a phrase with one tap, and Build a message and Letters cover everything else, from yes and no to real questions for the doctor. It does not replace speech. It covers the gap so the person can join the conversation today while therapy works on tomorrow.

For practice, Practice Out Loud plays a phrase, records a try and plays it back, with a playback speed control that slows the model phrase down. There is no grading, and the exercises a speech-language pathologist assigns appear there as encouragement. The stroke page shows how the rest of the app carries the recovery, from the hospital bed to Coming Home.
