Right Hemisphere Stroke: Side Effects, Treatment, & Recovery

Recovery from a right hemisphere stroke involves treatment to stop the stroke along with rehabilitation to restore the side effects that may occur.

Typically, a right side stroke create side effects that manifest on the left side of the body. That’s because each hemisphere of the brain controls the opposite side of the body.

Furthermore, the functions that the right hemisphere controls (like emotion, spatial reasoning, and creativity) may become damaged and require rehabilitation, too.

It’s important to understand what side effects may occur after a right sided stroke and which stroke recovery treatments may help – and this article will explain everything you need to know.

First up, we’ll discuss what a stroke is and how it’s initially treated.

Understanding Right Hemisphere Stroke

A stroke occurs when the supply of blood in the brain is obstructed and prevents an area from receiving enough oxygen-rich blood.

There are two main types of stroke: ischemic stroke where a blood clot obstructs an artery in the brain, and hemorrhagic stroke where a blood vessel in the brain bursts.

While a stroke is happening, the oxygen-deprived brain cells begin to die, which is why stroke is a medical emergency! Patients need treatment immediately to restore the normal flow of blood.

The best way to identify a stroke is to know the symptoms: facial drooping, weakness on half of the body, and slurred speech. Sometimes a piercing headache is involved, too.

Once the patients arrives in the hospital for treatment, doctors will restore blood flow either through clot-busting drugs (for ischemic stroke) or surgery (for hemorrhagic stroke).

After treatment, the road to recovery begins. Patients must work to overcome the side effects created by the impact of the stroke.

Side Effects of Right Hemisphere Stroke

After a stroke on the right side of the brain, what is damaged?

Each half of the brain controls the opposite side of the body. Therefore, a stroke on the right side of the brain often results in impairments on the left side of the body.

Furthermore, the functions controlled by the right hemisphere may become impaired, too. Right hemisphere strokes may result in the following stroke side effects:

Hemiplegia or Hemiparesis: Impaired Mobility on One Side

Hemiplegia involve paralysis on the affected side, and hemiparesis involves weakness on the affected side.

With a stroke on the right side of the brain, these impairments manifest on the left side of the body. Right side stroke survivors may struggle with moving their left leg, arm, or hand.

The size of the stroke may be correlated to the severity of the impairments. For instance, a massive stroke in the right hemisphere might lead to paralysis on the left side of the body instead of hemiparesis (weakness).

Prosopagnosia: Difficulty Recognizing Faces

After a right hemisphere stroke, some patients may have difficulty recognizing faces – a condition known as prosopagnosia.

Many suspect that inability to recognize faces is liked to damage to the fusiform gyrus (according to an article from CNN), which resides in the right hemisphere of the brain.

Damage in this region may cause right side stroke patients to not recognize family members’ faces, which can be distressing to loved ones.

Hemineglect: Unaware of Environment on Opposite Side

After a right side stroke, some patients may lose the ability to pay attention to the left side of their environment. For example, they may not eat the food on the left side of their plate because they are not aware that it’s there.

This is a condition called hemineglect where stroke patients have problems noticing and paying attention to the environment on their affected side.

To illustrate this problem, see the image above from the Journal of Neurology where a right sided stroke patient that was instructed to fill in the numbers on a clock.

You will notice that all the number have been crammed into the right side because the patient is neglecting the left side.

Hemianopia: Loss of Vision on Opposite Side

The visual cortex spans across both hemispheres of the brain, so vision problems can occur after a stroke on either side of the brain. The opposite field of vision will be affected.

When a stroke on the right side of the brain damages the vision cortex, is can blind patients on the left side – a condition known as hemianopia.

Anosognosia: Neglect or Denial of Disability

Unfortunately, some right side stroke patients are in denial of their disability because the stroke has impacted their self-awareness.

A condition called anosognosia occurs when a person with a disability is unaware of its existence. Anosognosia often results from damage to the parietal lobe or fronto-temporal-parietal area in the right hemisphere of the brain.

Unfortunately, this condition may prevent right hemisphere stroke patients from seeking treatment because they are in denial that disability exists to begin with.

Pseudobulbar Affect: Sudden Outbursts of Emotion

Some side stroke patients may find themselves having uncontrollable outbursts of emotion like laughter or crying, often unrelated to the situation. This condition is called pseudobulbar affect or emotional lability.

Patients with pseudobulbar affect may laugh at something that isn’t nearly funny, for example, or they may laugh at something that’s sad.

This condition is neurological and occurs in about half of stroke patients. It should not be confused with other psychiatric disorders like post-stroke depression.

Now that you understand the side effects of a stroke on the right side of the brain, what can you do for rehabilitation?

Rehabilitation Methods for Right Hemisphere Stroke Patients

Rehabilitation and treatment of a right side stroke involves restoring as much function as possible.

The side effects listed above can be remedied, at least partially, by participation in the following rehabilitation methods and stroke recovery treatments:

  • Physical Therapy. Massed practice of physical therapy stroke exercises can help improve movement after stroke. Patients with left-side paralysis can use their right arm to assist the body through exercises if necessary.
  • Cognitive Therapy. A speech-language pathologist can be a great asset during recovery from a right side stroke. SLPs are trained in helping you recover speech and cognitive function, like object recognition, which can help with conditions like prosopagnosia. Two SLPs came together to create the CT Speech and Cognitive Therapy App to provide speech and cognitive therapy conveniently from your phone or tablet.
  • Attention Training. When hemineglect is involve, patients can turn their head to the left side to bring awareness into their affected side’s environment. Although this is a compensation technique, it helps train the brain to pay attention to the left side.
  • Vision restoration therapy. Vision problems after stroke should be treated with the help of a team of specialists. Sometimes corrective eyewear from an optometrist can help. Other times participating in vision restoration therapy may help. Because vision is essential for driving and carrying out daily tasks, it’s important to seek professional help.
  • Psychotherapy. Some side effects of a right hemisphere stroke affect a patient’s personality. For example, if anosognosia is involved, the patient is in denial that there’s a problem to begin with. One possible solution is a form of talk therapy called motivational enhancement therapy. Ideally, this can help improve self-reflection and reduce the patient’s resistance to treatment.
  • Positive Psychology. Another approach to personality and emotional changes after a right hemisphere stroke is positive psychology. This modality focuses on enhancing positive emotion by rewiring the brain for happiness. The book Healing & Happiness After Stroke is a great resource for this.

These are some of the most popular remedies for right side stroke side effects.

Right Hemisphere Stroke Recovery

It’s important to note that rehabilitation takes time and the duration varies among patients.

Fortunately, your brain is on your side! When you put in the work during rehabilitation, the brain works hard to rewire itself through neuroplasticity.

The brain just needs your help by putting in the time and the reps.

You can also support yourself by talking to your therapist to generate a treatment plan for your unique right hemisphere stroke recovery. Good luck!
