Why memory and personality not affected after brain hemispherectomy

In summary, hemispherectomy, the surgical removal of one half of the brain, is often performed on epileptic patients or for other reasons. However, this procedure has shown no significant changes in the patient's memory or personality. It remains unclear how this can be explained, and further research is needed. To properly address this question, please provide mainstream studies from acceptable journals and cite specific portions for discussion.

Because when parts or one half of the brain(hemispherectomy) is removed on treating epileptic patients or for any other reason. There is not observed any change in the patient memory or personality.

The person remain the same even after removal of half of the brain. How is it explained?

Thanks.

You will need to post the mainstream studies posted in acceptable journals on this. Once you have the proper sources to cite, then you can ask about specific questions in those papers. Be sure to quote the portion to which you are referring, do not make people read through the entire paper trying to find what you are referring to. Once you have this all together, please post it in medical sciences.

FAQ: Why memory and personality not affected after brain hemispherectomy

1. Why does removing half of the brain not affect memory and personality?

Removing half of the brain, also known as a hemispherectomy, does not necessarily affect memory and personality because the brain has the ability to reorganize and compensate for the missing hemisphere. This is known as neuroplasticity, where the remaining hemisphere can take on the functions of the removed one. Additionally, memories and personality traits are not solely located in one hemisphere, but rather distributed throughout the brain.

2. How is it possible for someone to function normally after a hemispherectomy?

Individuals who have undergone a hemispherectomy may still have some degree of impairment, but they are able to function normally due to the brain's ability to adapt and rewire itself. The remaining hemisphere takes on the functions of the removed one, allowing the individual to continue with their daily activities.

3. Are there any long-term effects of a hemispherectomy on memory and personality?

While there may be some short-term effects, such as temporary memory loss or changes in personality, there are typically no long-term effects on memory and personality after a hemispherectomy. As mentioned before, the brain is able to compensate for the missing hemisphere and maintain normal functioning.

4. Can a person's memory and personality change after a hemispherectomy?

In some cases, there may be minor changes in memory or personality following a hemispherectomy, but these changes are often temporary and can be managed with rehabilitation and therapy. The remaining hemisphere may need some time to adjust and take on the functions of the removed one, but the individual's core memory and personality traits usually remain intact.

5. How does a hemispherectomy affect different age groups?

The effects of a hemispherectomy may vary depending on the age of the individual. Younger children tend to have a better chance of full recovery and may experience less long-term effects due to their brains' higher level of plasticity. However, adults who undergo a hemispherectomy may have a longer recovery time and may experience more significant changes in memory and personality. Overall, the brain's ability to adapt and reorganize helps individuals of all ages to function normally after a hemispherectomy.
