One of the main signs of Alzheimer’s disease is what is known as plaques in the brain. It is made of abnormal proteins and damages healthy brain cells. Little by little, brain cells die and plaques grow larger. The consequences for the patient are memory impairment and Mental illnessWhich reduces the quality of life with age. But now there is good news. Because researchers have found that not all plaques in the brain are harmful. There are also protein deposits that have a beneficial effect.
Alzheimer’s disease: what role do different types of plaques play in the brain?
In a frame studying Researchers at the Salk Institute for Biological Studies in La Jolla, California, USA found that there are two types of panels. The spreading plaque already has a harmful effect and leads to the death of healthy brain cells. However, the combined sediments have a positive protective effect. Scientists and medical professionals have so far assumed that the two types form spontaneously. However, it is now found that the diffuse variant forms spontaneously, but the second type, the second type of plaque, forms in the body as a semi-immune response to the diffuse plaque. These plaques are designed to serve the purpose of removing harmful debris from nerve cells in the brain and preventing healthy cells from dying.
The scientific team has not been able to prove that the compact plaque is harmless. But researchers have come to the conclusion that these cause at least less damage to the brain.
Study results are an important starting point for later drug development. Medical professionals are of the opinion that the combined plaques do not need to be attacked. Instead, you should focus on the metastatic plaques and try to develop effective drugs. Unfortunately, at this point in time, scientists around the world have not been able to develop treatment approaches for Alzheimer’s patients.
