Right Brain May Help Predict Recovery Of Language In Stroke

Left and Right Brain Infographic

Left vs right brain is a debate that’s talked about frequently. Apparently, who you are is influenced by which part of the brain is more dominant in your body. Different subjects require different parts of your brain – for example, subjects like Mathematics would require more of your left brain, while subjects like creative writing would use your right brain more often.

When you have an ischemic stroke, the oxygen-rich blood supply to part of your brain is reduced. With a hemorrhagic stroke, there isbleeding in the brain.

After about 4 minutes without blood and oxygen, brain cells become damaged and may die. The body tries to restore blood and oxygen to the cells by enlarging other blood vessels (arteries) near the area.

If blood supply isn’t restored, permanent damage usually occurs. The body parts controlled by those damaged cells cannot function.

In TCM however, there are four agents of stroke – Wind, Fire, Phlegm and Stasis. The internal organs most likely to be weakened by these factors are the kidney and spleen, causing deficiencies of Chi, Blood, and Yin. Deficiencies of Chi, Blood, or Yin permit the body to be overwhelmed by the pathological factors of Wind, Phlegm, Fire, and Stasis, resulting in such stroke-related patterns as Liver Yang Rising, Stasis of Chi or Blood, Phlegm combining with Fire, Liver Wind, or Wind in the Meridians.

Regardless of the cause, a fascinating discovery has been made, that the structure of the right brain can predict the recovery of language in stroke.

Results showed that patients with aphasia (the impaired ability to understand speech) and better results in speech-fluency tests were more likely to have higher structural integrity than the control group in three areas of the brain.

The three areas were the right middle temporal gyrus, the right inferior frontal and the right precentral gyrus. The gyri (Or gyrus) are the “bumps” that can be seen on the surface of the brain. The folding created by the sulci and gyri increases the amount of cerebral cortex that can fit in the skull.

The correlation scores between the amount of injury to the left hemisphere and speech-fluency scores improved when the right hemisphere information was added to the analysis.

Thus, this study reveals that a well-wired right brain actively supports speech recovery.

To end off, learn about the nutritional values of foods normally consumed in order to pinpoint which vitamins or minerals might be missing. To be healthy and active, the brain also needs exercises that help stimulate the right hemisphere of the brain and activate deeper thought processes. Exercises like yoga and knitting can help stimulate the right brain as well.
