COVID-19 Study Links Alzheimer's-Like Issues in Brain and Eyes
Imagine COVID-19 as a tiny invader that can cause problems in your brain and eyes, like the ones seen in people with Alzheimer's disease.
Scientists found that this invader can lead to the buildup of a protein called amyloid beta.
This protein buildup is also linked to Alzheimer's.
Researchers discovered that a protein called NRP1 may let the invader into your brain and eyes.
However, they found a way to stop the invader by using an NRP1 inhibitor.
Scientists are now studying if COVID-19 can increase the chances of developing Alzheimer's in the long run.
COVID-19 may trigger Alzheimer's-like protein buildup in the brain and eyes.
Elevated amyloid beta levels were found in the retinal tissue of people who had COVID-19.
NRP1 protein may serve as an entry point for viruses into the eyes and brains.
Introducing an NRP1 inhibitor countered the amyloid beta increase caused by COVID-19's spike protein.
Researchers are conducting clinical studies to determine if COVID-19 increases the risk of Alzheimer's disease.
