Research shows root cause of Alzheimer’s disease

Alzheimer’s disease is a condition that mainly affects older people, leading to severe memory loss, confusion, and changes in behavior.

It’s the most common cause of dementia, a broad term for brain diseases that make it hard for people to think clearly and manage their daily lives. Despite many efforts, finding a cure has been challenging, leading scientists worldwide to dig deeper into what causes Alzheimer’s.

For a long time, experts have had two main ideas about what leads to Alzheimer’s. The first idea suggests that the disease starts when a specific protein, called amyloid-beta, piles up in the brain, making it hard for brain cells to talk to each other.

The second, newer idea thinks the real trouble starts when the mitochondria, the powerhouses inside our cells, don’t work right.

A recent study by Jan Gruber and his team at Yale-NUS College has shed new light on this mystery. They studied a tiny worm, known as Caenorhabditis elegans, which, believe it or not, shares many of the same cell types as humans.

Their findings were surprising. They discovered that problems with how the worm’s cells produced energy showed up before any signs of the amyloid-beta protein building up.

One of the most exciting parts of their research was about a common diabetes medicine called Metformin. When they gave this drug to the worms, it fixed their energy production issues and helped them live a normal, healthy life again.

This suggests that if we can correct these energy issues in people, we might be able to stop Alzheimer’s before it even starts.

The study goes even further to suggest that Alzheimer’s and other diseases that usually affect older adults might not be separate diseases at all.

They could just be different ways our bodies show signs of aging. So, by figuring out how to slow down or reverse aging at the cellular level, we might help prevent diseases like Alzheimer’s.

This discovery is a big deal. It points us in a new direction for fighting Alzheimer’s, focusing on the health of our mitochondria and how our cells produce energy.

But, as always, more work is needed to see if what works for worms works for humans too. Researchers are eager to explore whether drugs like Metformin can safely and effectively prevent Alzheimer’s in people.

This research, which was published in the eLife scientific journal, is a beacon of hope. It suggests we might be on the brink of understanding Alzheimer’s in a whole new way, leading to better treatments or even a way to stop the disease before it starts.

While we haven’t solved the mystery of Alzheimer’s completely, this study adds a crucial piece to the puzzle, giving us hope for a future where Alzheimer’s can be prevented or cured.
