Does melatonin cause memory loss?

In studies with rat models of Alzheimer's disease and similar conditions, melatonin was tested to see its impact on memory. Researchers found that when melatonin was given to rats, it helped reduce issues that usually lead to memory loss. Specifically, melatonin reduced the buildup of harmful proteins and helped protect brain cells.

These findings suggest that in the animal studies, melatonin did not harm memory; instead, it seemed to offer benefits to memory by stopping or slowing damage that can lead to memory issues.

Even though these tests were done on animals and not directly on humans, they tell us that melatonin might be helpful in protecting the brain and memory.
