Low Serotonin Levels Linked to Dementia, Discovered through MRI Scans

Low Serotonin Levels

Forgetting where you put your keys or the name of a distant relative is one thing, but frequently forgetting what you did a few minutes ago is another. You must be suffering from some kind of dementia, a group of symptoms characterized by cognitive decline.

While current treatments cannot prevent the progression of Alzheimer’s disease, however, they can temporarily slow it down to improve the sufferer’s quality of life.

Perhaps the main reason why Alzheimer’s disease still doesn’t have a cure is that its causes are still unknown. Researchers are working hard to discover these causes and finally develop a cure. One factor they are looking at is the link between the disease and the brain’s serotonin levels. They found through MRI that people with Alzheimer’s disease have less of this chemical in their system. Continue reading
