What if I had a brain tumor?
The next time you’re sitting down to a meal, take a look at your brain.
Researchers are already working to understand how brain tumors grow and how they affect our everyday lives.
A new study from the University of Utah and the Johns Hopkins University is the first to analyze brain scans from healthy people and show that tumors can cause cognitive impairment.
The study, published online this week in the journal Neurosurgery, looked at how brain tumor lesions affect people’s mental function, from how they remember to their ability to perform tasks like driving.
The researchers found that some people with brain tumors experienced impairments that were comparable to those of people who have Parkinson’s disease.
Brain scans also revealed that people with tumors had a higher risk of mental impairment than those without tumors.
While people with a tumor in the right brain hemisphere have a more normal functioning brain than those with a normal brain, the researchers found some individuals with tumors in the left brain hemisphere did not.
“We found that the tumors affected different regions of the brain and different regions are impacted by different brain tumor types,” said co-author Alex Deutsch, a professor of neurology and neurosurgery.
“That means that some areas of the right hemisphere are less affected than others, and the right and left brain areas can be affected by the same brain tumor.”
For example, researchers found a higher rate of impairment in people with left hemisphere tumors, but they did not see an increase in impairment in those with right hemisphere tumors.
“I think that is a pretty good example of the fact that there is no single region that is more impacted by brain tumor than any other region,” Deutsch said.
“It is the different areas that affect different people differently.”
The study also found that brain tumor activity correlated with other mental disorders, like depression and anxiety.
People with multiple brain tumors had increased risk of having cognitive impairment and cognitive decline, compared to people with the same number of brain tumors.
A second study from University of California San Diego, also published in Neurosurgeon, looked to see if brain tumor abnormalities correlated with the onset of dementia.
They found that people who had brain tumors at an earlier age were more likely to have dementia at an older age, even after controlling for other factors.
Brain tumors also appear to affect how we process information, and researchers are working on ways to understand why some of us develop problems with our cognitive functions.
“The brain is a huge organ that does a lot of complex things, but there is so much more going on than what you think,” said Deutsch.
“For example, the brain has more neurons than your fingernails.
You know that you have one nerve for everything that you do, but your brain has about a billion more connections than your fingers.
That is very, very, much more than you think you have.
It is the brain’s wiring.”
The University of Pennsylvania study, also in NeuroSurgeon, found that there was no correlation between how much brain tumor damage people experienced and how long they had to live.
This study shows that the brain is an amazing organ, and we need to pay attention to how we treat and treat it appropriately.
Deutsch added that there are many things that the study showed, including that there may be more damage in people who develop dementia later in life.
He is optimistic that these findings could lead to new therapies to treat dementia and dementia-related problems, as well as improve brain health.
“One of the things that I am most hopeful about is that these results provide a starting point for understanding how brain tissue may behave differently in people after brain tumor removal,” Deutz said.
