Left Brain Damage: effects + therapy activities that can help

If you or your loved one has recently sustained a left hemisphere brain injury — due to a stroke or other brain injury — you may be overwhelmed with questions like:

  • What role does the left brain play in everyday life?
  • How does left-sided brain damage impact cognitive processing capabilities?
  • What differentiates a left side brain injury?
  • What tools might be available to help regain valuable skills during the recovery journey?

In anticipation of Brain Injury Awareness Month in March, this post will answer those questions and provide an overview of specific Constant Therapy exercises that may help in recovery from a left brain injury.  

What is the left side of the brain responsible for?

The brain is divided into two hemispheres, left and right, which are bridged by the corpus callosum, a bundle of nerves that functions like a highway to connect the two sides of the brain. While the left and right sides of the brain do communicate with one other, each hemisphere has primary control over particular functions. 

Counterintuitively, each side of the brain controls the opposite side of the body. One of the key functions the left brain is responsible for, therefore, is right side body mobility. 

Beyond that, the left hemisphere of the brain is especially important for language expression and comprehension. This is in part because several brain regions especially critical for language, such as Broca’s area and Wernicke’s area, are located in the left hemisphere of the brain. The left brain is therefore largely responsible for speaking, listening, reading, writing, and grammatical processing. 

The left hemisphere is also crucial for logical reasoning skills—including numeracy, computation, and information processing—and executive functions like time awareness.

What is a left-side brain injury?

Due to the relative specialization of brain function, injuries to a particular hemisphere of the brain often assume common characteristics. Such damage can result from a traumatic brain injury, which typically follows a sudden, strong physical impact to the brain, or a non-traumatic brain injury, which can be caused by oxygen deprivation (during a stroke, for example) or chemical exposure. 

A left brain injury occurs when the left cerebral hemisphere sustains damage that impacts its functioning. It is important to keep in mind, however, that many brain injuries ultimately affect both sides of the brain.

What would be impaired if the left side of your brain were injured?

Every brain, and every brain injury, is unique. It is impossible to predict how an injury to the left cerebral hemisphere might manifest in a specific individual. However, there are patterns of brain damage that have been broadly observed by researchers and clinicians. 

When the left side of the brain is damaged from a neurological injury (like a TBI) or event (like a stroke), language difficulties are one of the most common side effects. People who experience left brain injuries might have difficulty producing and comprehending spoken and/or written language (aphasia); coordinating the motor aspects of speech (apraxia); or with slurring their speech (dysarthria).

Left side brain damage may also result in challenges with numerical computations (such as counting or math operations) and processing and solving complex problems. 

Movement on the right side of the body is also commonly affected with left side brain damage, and it may result in weakness and decreased sensitivity on the right side as well.

    I have left brain damage & have all the symptoms you list. I was diagnosed with Post Concussive Syndrome in 2022 from a fall in 2018! Doctors question why I haven’t recovered from PCS. I have no idea nor understand any of it. I just know we have thousands of $$ medical debt right now. I had this in the past but wonder about 1 mo. March for help. ??

    • Constant Therapy

      • Nancy Averill

        With the above writer’s question about Post Concussive Syndrome, is it sensory issues that continue after the first month, or is it similar to TBI or Longterm Covid patients?

        • Constant Therapy

          Nancy, thanks for the question! It’s hard to say, because PCS can present differently between people. If you are experiencing PCS symptoms and/or sensory issues, we recommend speaking with a healthcare provider to get the appropriate answers & support. Hope this is helpful!

  4. Art Hamid

    I did the excercises for three months after my stroke then lost interest. Did not see much progress. I do not understand why I am resisting.

  5. Karen Zylman

    Hello. I am a Recreation Therapist working at Providence Hospital in Southfield Michigan. I receive your emails and have had a presentation from Constant Therapy for my Stroke Support Group. The information is well organized.

    I am presenting to the Michigan Therapeutic Recreation Association on March 24th, 2023. Would you give permission for me to include some of the info and graphics, if I credit you and include you in my sources?

    • Constant Therapy

      Hi, Karen- Yes, absolutely! Feel free to use our graphics with attribution. We have heard from Recreation Therapists that they use Constant Therapy in group settings to engage patients — with excellent results.

  6. Virginia

    Hi, my 2 year old son was found that his left brain side is injured. The neurologist said that there is nothing that can be done.

    Is there any help for him.

    • Constant Therapy

      Hi Virginia, we are so sorry to hear about your son. The brain’s neuroplasticity is very powerful, which you can read more about in this BrainWire post. In terms of treatment, we recommend talking with your current healthcare provider, or perhaps seeking a second opinion from another neurologist. Best of luck to you and your son!

  7. Hope Cristobal

    I had a left brain stroke 10 months ago; was admitted 5-days and have not had any other treatment. Is it too late to address memory issues at another hospital?

    • Constant Therapy

      Hi Hope! No, it’s never too late to work on your speech and cognitive skills after a neurological event such as a stroke. We cannot speak to the process of getting set up at a different hospital, but we would be happy to provide you more information about Constant Therapy and neuroplasticity. If you have any questions feel free to email us at
