A genetic mutation in the immune system of the brain protects against various forms of dementia
Genetic mutation protects against dementia - brain short science news

A mutation in the PLCG2 gene protects against various forms of dementia. Carriers of this mutation have a greatly increased chance of turning 100 without dementia. This finding is the result of genetic research conducted with no less than half a million of hundred-year-olds worldwide.

PLCG2 is part of the immune system in the brain, suggesting that dementia is a result of faulty immune function in patients.

Researchers now try to determine why PLCG2 protects against dementia, so that this effect might be mimicked by medication in the future.
