Has a stroke affected your speech? It could be a sign of aphasia or apraxia of speech. Both conditions can inhibit a stroke survivor’s speech and communication.
To help you understand how to recover speech after stroke, this article will outline how stroke can affect speech. Then we will discuss available treatment options.
Types of Speech Problems After Stroke
When stroke affects speech, it’s often the result of a left hemisphere stroke. This is because the language center of the brain resides in the left hemisphere.
Generally speaking, there are 2 main types of speech problems that occur after stroke: aphasia and apraxia of speech.
Aphasia involves difficulty producing and/or interpreting language. Aphasia can be broken down into 3 types: receptive aphasia, expressive aphasia, and global aphasia. Each type is treated with different rehabilitation techniques, so it’s important to get a formal diagnosis.
Apraxia of speech involves difficulty with voluntary muscle control for speech. In other words, patients cannot properly control their lips and tongue enough to produce clear speech. As a result, the patient may slur their words or not speak at all (more on this later).
Language difficulties after stroke have many nuances, and they are treated with different rehabilitation techniques. Therefore, it’s imperative to work with a specialist called a Speech-Language Pathologist for a formal diagnosis.
Next, we’ll discuss the treatments and timeline.
Rehabilitation for Speech Problems After Stroke
Recovering speech after stroke revolves around neuroplasticity: the brain’s ability to create new pathways and strengthen old ones. Skills lost after stroke, like language and communication, can be restored by creating new neural networks in the brain.
The key to activating neuroplasticity is repetition. The more you practice a skill, the better you get.
For this reason, Speech-Language Pathologists greatly rely on speech therapy exercises to help stroke patients regain their speech. By practicing the skill of speech, patients can get better.
Speech therapy is not usually easy. Many stroke patients compare speech rehabilitation to learning how to talk for the first time. This isn’t far from the truth.
After a stroke has damaged the language center of the brain, the brain must use new, healthy areas to control the function of language. This often feels like learning how to speak as if for the first time.
But even if you’re mentally prepared for difficult the road ahead, how do you know which speech exercises to use?
Exercises Used to Improve Speech After Stroke
There is no one-exercise-fits-all regimen for speech therapy. The speech therapy exercises that help one person may not help another.
For instance, some stroke patients might speak with clarity but struggle with comprehension. Others might comprehend speech correctly but struggle with word formation.
This is where SLPs really help. By providing a clear diagnosis, they can target your speech difficulties with specific exercises.
For example, exercises for aphasia may involve reading comprehension and naming therapy. Whereas exercises for apraxia of speech, which focus on motor control, may involve tongue exercises. These are just a few examples out of hundreds of possibilities.
Therefore, one set of speech therapy exercises will not benefit all stroke patients with affected speech. Rather, every patient needs a highly individualized plan.
Usually, it works best to work with an SLP one-on-one and then use speech therapy apps at home. We recommend the CT Speech & Cognitive Therapy App, created by SLPs, because it assigns specific exercises based on your needs.
How to Recover Speech When You Can’t Talk At All
Now that you understand the best stroke treatment for speech and language difficulties, we’d like to discuss a very important caveat: What if you can’t talk at all?
Surprisingly, even when a stroke patient can’t talk at all, they can usually sing. That’s because language is a left-brain function, but singing is a creative right-brain function.
When a stroke occurs, it usually only happens on one side of the brain (bilateral strokes are the exception). This means when the language center in the left hemisphere is damaged, the right hemisphere is undamaged. This preserves “right-brained” skills like singing.
Therefore, patients who can’t talk at all should begin aphasia treatment with singing therapy. It does not come easy, and progress takes time. But over the course of many weeks, patients can begin to recover speech.
How Long Does Speech Recovery Take?
Speech recovery after stroke is highly individualized. The rate of recovery depends upon the severity of the stroke and how consistently the patient participates in speech therapy.
Over 33% of stroke patients have some form of speech problem immediately after stroke.
Many recover within a few months, but 60% continue to have speech problems over 6 months post-stroke.
However, slow recovery is likely due to low volume of treatment. When insurance stops covering time with an SLP, many patients stop speech therapy altogether, which stops recovery as a result. (See: what to expect 5 years after stroke for more info.)
That’s why it’s important to continue speech therapy at home with speech therapy apps. This provides the brain with the stimulation needed to keep recovery going well past the 6 month mark.
Overcoming Speech Problems After Stroke
Speech problems after stroke are often diagnosed as aphasia or, less commonly, apraxia of speech. These conditions are common in left hemisphere stroke patients.
It’s best to work with a trained Speech-Language Pathologist for a diagnosis. They can create an individualized exercise plan and even help you use speech therapy apps with success.
To achieve your highest recovery, it’s important to be consistent. The more you practice your exercises, the more your speech will improve. Good luck on the road to recovery ahead.
