Alzheimer’s disease is a common brain illness in older people. It is the main cause of dementia, which leads to memory loss, trouble thinking, and changes in behavior.
While some treatments can help with symptoms, scientists have not yet found a complete cure. This has led researchers around the world to search for the true cause of Alzheimer’s.
For a long time, there have been two main ideas about what causes this disease. The first idea is that a protein called amyloid-beta builds up in the brain and blocks how nerve cells communicate.
The second idea, which is getting more attention now, is that the problem may come from how cells make energy. This energy is made in parts of the cell called mitochondria.
A new study from Jan Gruber at Yale-NUS College supports this second idea. The scientists used tiny worms called Caenorhabditis elegans for the study. These worms are simple creatures, but they have many things in common with human cells. The researchers found that problems with cell energy started before the harmful amyloid-beta protein showed up.
One of the most exciting parts of this study is the use of a drug called Metformin. This drug is normally used to treat diabetes. When the researchers gave Metformin to the worms, their energy problems were fixed. Their health and lifespan returned to normal. This means that fixing energy production in cells might help stop or delay Alzheimer’s.
The study suggests that diseases like Alzheimer’s may not just be separate conditions, but part of the aging process itself. If we can understand and treat the basic problems that come with aging, we might be able to prevent many age-related illnesses, not just Alzheimer’s.
This new way of thinking could change how scientists study aging and disease. Instead of focusing only on each disease, they might look at how aging affects our cells and how energy is made and used. The study shows that improving the way cells make energy could be a big step forward in treating Alzheimer’s.
But we are not there yet. Before Metformin or similar drugs can be used to treat Alzheimer’s in humans, more research is needed. Scientists have to make sure these treatments are safe and really work in people.
The study was published in a science journal called eLife. It does not solve the Alzheimer’s mystery, but it does give a new clue. It shows a possible new direction for research, treatment, and prevention.
In the end, this research gives hope. By focusing on how aging works inside our bodies, we may find new and better ways to fight diseases like Alzheimer’s. This approach could help us live healthier lives as we grow older.
