The doctors discovered that a certain protein is released by the phagocytes and that the immune system in the brain also shows increased activity.

The disease manifests itself through inflammation

If the immune system is particularly active, this indicates that inflammation is being fought in the brain. In addition to the formation of so-called protein plaques, these inflammations are regarded as precursors and triggers of dementia. The activity of the phagocytes is stimulated by dying brain cells. The phagocytes probably have a protective function that diminishes as the disease progresses. The aim of research is therefore to increase the activity of scavenger cells again.

The earlier the therapy begins, the better

As these processes can be detected before symptoms appear, Alzheimer's could be treated earlier and therefore more effectively in future.
