Summary:
- Researchers have discovered unexpected effects of the diabetes drug metformin on the brain. Metformin is one of the most commonly prescribed drugs worldwide, used to treat type 2 diabetes.
- The study found that metformin can cross the blood-brain barrier and accumulate in the brain, where it alters the metabolism and function of brain cells. This includes changes in the activity of mitochondria, the powerhouses of cells.
- These findings suggest metformin may have potential therapeutic applications beyond diabetes, such as in neurological and psychiatric disorders. Further research is needed to fully understand the implications of metformin's effects on the brain.
