"... plasma proteins, GFAP, NEFL, GDF15 and LTBP2 consistently associated most with incident all-cause dementia (ACD), Alzheimer’s disease (AD) and vascular dementia (VaD), and ranked high in protein importance ordering."

Now is there something that can be done early or is it 15 extra years of suffering

From what I understand, the medicine available is fairly successful at staving off further disease progression but the normal late stage diagnosis often means it’s far too late. This might make outcomes significantly better if it works as well as reported.

One caveat is that this is necessarily a retrospective study. The authors looked at historical data from the UK Biobank, ran a regression, and found these genes. So, it’s not really clear if these genes are actually causing dementia, or if they’re just related to a common cause, or (most likely) tied together through some very complicated web of biological mechanisms.

That said, they’re interesting genes. GFAP is expressed in astrocytes, which are glial cells. These perform a lot of tasks in the brain, but they seem important in protecting neurons from toxic stresses. So, this may give us some additional insight into the role of glial cells like astrocytes in dementia.
