A new research revealed some of the complex mechanisms behind the plaques in the brain which are the trademark of Alzheimer’s. The fatal disease of brain accompanied by confusion, memory loss and finally makes oneself unable to care for him.
The researchers studied the brains of mice, having Alzheimer’s like plaques in the brain, with the help of an advanced optical imaging technique. They found that the same proteins (prions) in mice, which are known for playing havoc in the diseases of mad cow and Creutzfeldt-Jakob, hit by amyloid beta that made them toxic.
It was observed that a star-shaped type of brain cell (astrocytes), which helped in the normal functioning of the brain, turned to hyperactivity in the presence of amyloid plaques.
A new study says that you can avoid the devastating impact of Alzheimer’s disease on memory if you go to university and then choose a mentally demanding job for yourself, as the researchers find that less intellectual stimulation often causes to quick tissue damage that leads to memory loss.
The researchers suggest that tough mental work or genes that make people have such careers may prove helpful for the brain to compensate for disease.
This Italian study has been published in the journal Neurology.
There are many other studies (based on age and symptoms) that suggest mental activities can help to avoid Alzheimer’s.
The researchers from the San Raffaele University, Milan used brain scan tests to examine the distinctive ‘tangles’ and protein deposits characteristic of Alzheimer’s in 242 old people. In these people 144 had no memory problems, while 72 had mild cognitive impairment.
