A new study revealed that the loss of a sense of smell can be an important and early indication of Alzheimer’s disease.
Losing the sense of smell is an indication of Alzheimer’s infection
According to what was published by the Times Now News website, there is a new study that concluded that the weakness of the sense of smell may be one of the oldest indicators of this situation, as it appears even before the emergence of cognitive weakness and while previous research identified the weakness of the sense of smell as a potential early indicator of Alzheimer’s disease, but its mechanisms are still mysterious.
In the new research, the scientists sought to detect the neurological foundations of the disease, by analyzing the PET CT scans and samples of the brain tissue of mice and human beings.
The results indicated that the immune response to the brain plays a major role in losing the sense of smell associated with Alzheimer’s disease, as it appears to destroy the nerve fibers that the brain needs to perceive the odors, and the study found that immune cells specialized in the brain, known as small glial cells, cut off the connections between the olfactory and blue place.
The olfactory onion: It is a structure at the front of the brain that receives and analyzes signals from the smell receptors in the nose, then sends information to other parts of the brain for treatment.
As for the blue site, it is located in the brain trunk, but it affects the olfactory onion and other brain areas through long nerve fibers. The nerve scientist Lars Begger of the German Center for DZNE Neurological DZNE and Ludwig Maximilian University in Munich LMU shows.
