From Mitochondrial Function to Neuroprotection - PubMed Central

Methylene blue (MB) is a drug that has been used for many years to treat conditions like malaria and poisoning. Recently, scientists have found that it can help improve how our cells work, especially in the parts of the cell that create energy, called mitochondria. MB works by helping the mitochondria function better, which can reduce stress in cells and improve their ability to do their job. This has led to interest in using MB to help with brain health, as it can also reduce inflammation in the brain.
Mitochondrial problems are common in diseases like Alzheimer's, Parkinson's, and after brain injuries. Studies have shown that MB can help protect the brain and improve behavior in animals with these conditions. It also seems to help with brain repair and improve memory, making it a potential treatment for age-related memory loss. In short, MB could be a useful tool for improving brain function and treating diseases that affect the brain.
