Alzheimer’s disease is a condition that impacts older people around the world. It is a type of dementia that causes problems with memory, thinking, and behavior.
For over two decades, scientists across the globe have been trying to uncover the exact causes of Alzheimer’s.
Up until now, they haven’t found a sure-fire cure. Let’s dive into the mysterious world of Alzheimer’s and uncover some of the latest research on this disease.
What is Alzheimer’s Disease?
Alzheimer’s disease is a condition that primarily affects older adults.
It’s the most common type of dementia, a term that describes a range of conditions that cause memory loss and other mental abilities severe enough to interfere with daily life.
In Alzheimer’s disease, the brain’s cells gradually die off, leading to a decline in a person’s cognitive abilities.
Theories About the Cause
There are currently two main theories about what causes Alzheimer’s disease.
The first theory suggests that a specific protein called amyloid-beta builds up in the brain, leading to the disease.
This protein can clump together and form plaques that disrupt the communication between brain cells.
The second theory, which is newer, focuses on the idea of metabolic dysfunction. This theory suggests that the tiny parts of our cells that produce energy, called mitochondria, aren’t working properly.
A Breakthrough Study
A recent study from Yale-NUS College has found evidence to support the second theory: that metabolic dysfunction could be a primary cause of Alzheimer’s.
They found that these metabolic problems happened before there was a significant increase in the amount of amyloid-beta protein in the brain.
For their research, the scientists used a tiny worm called Caenorhabditis elegans. This worm is often used in scientific research because it shares many similarities with human cells.
The Power of an Anti-Diabetes Drug
The scientists made an exciting discovery during their research. They found that an anti-diabetes drug called Metformin could reverse the metabolic defects they observed.
When the worms were treated with Metformin, their health and lifespan returned to normal.
This suggests that targeting metabolic defects, especially problems with the mitochondria, could be an effective strategy for preventing Alzheimer’s.
It might be even more beneficial to do this early on, before there are any protein buildups in the brain.
A New Perspective on Aging and Disease
The researchers argue that metabolic and mitochondrial problems are fundamental features of aging.
Therefore, diseases like Alzheimer’s, which become more common as we age, might actually be manifestations of the aging process itself.
This means that it might be easier to prevent or treat age-dependent diseases like Alzheimer’s by targeting the mechanisms of aging, rather than treating individual diseases after symptoms have already appeared.
This study has shed new light on our understanding of Alzheimer’s disease. While we still have a lot to learn, it’s clear that the metabolic function of our cells plays a significant role in the development of this condition.
The research from Yale-NUS College is a step forward in our ongoing journey to understand, prevent, and ultimately cure Alzheimer’s disease.
The study, led by a scientist named Jan Gruber, was published in a scientific journal called eLife.
