Reactions: Spanish researchers propose new genetic form of Alzheimer's disease
Genetic forms of Alzheimer's are considered to be those in which certain variants of a gene inevitably lead to the disease over time. Until now, only rare alterations in three genes were considered as such. A group of researchers led by the Hospital de Sant Pau in Barcelona has proposed a new, much more frequent form. After analysing data from more than three thousand donated brains and clinical data from more than ten thousand patients, they found that almost all people who carry two copies of the ApoE4 variant in the ApoE gene, which was previously only considered a risk factor, also end up developing the disease.They publish the results in the journal Nature Medicine.
