The brain' immune system is the key to reverse dementia, says a new study. Researcher Michael Schwartz said that findings showed for the first time that a diseased brain was able to fight the debilitating condition.
In the study, when the researchers reduced the cells that prevent the immune system from reacting, they saw a significant drop in symptoms of dementia.

They blocked the action of regulatory T cells, which consequently allowed immune cells to enter the brain.
Inflammation and clumps of 'plaque' on the brain were reduced and the mice performed better in cognitive tests. Schwartz said the therapy not only halted the condition but reversed it.
