June is Alzheimer’s and Brain Awareness Month.
Alzheimer’s illness is ruthless. It could possibly rob you of your reminiscence, character and the flexibility to do easy issues like swallow or converse.
Even scarier: Nearly 2 out of three individuals with Alzheimer’s are girls or individuals assigned feminine at delivery.
However there’s excellent news within the screening developments for Alzheimer’s. There at the moment are blood checks that may assess your threat degree for Alzheimer’s — and you will get one proper now. However do you have to?

Blood check for Alzheimer’s
There are two kinds of checks that examine for acknowledged markers of Alzheimer’s illness. One which measures ranges of beta -amyloid proteins and one other that measures phosphorylated tau (p-tau) proteins.
“A few of these blood-based checks work higher than others,” mentioned Lynn M. Bekris, Ph.D., principal investigator on the Cleveland Clinic’s Lynn Bekris Lab. “The brand new blood checks for p-tau biomarkers are very promising.”
Earlier this 12 months, in a groundbreaking study, researchers precisely examined for elevated ranges of p-tau, a trademark for Alzheimer’s, from a daily blood check.
That is notable for a couple of causes. First, the check outcomes have been as correct as the present FDA-approved spinal faucet fluid check and mind scan used to determine and assist diagnose Alzheimer’s illness.
This implies a blood check might be able to change the extra invasive process with out compromising outcomes. And blood checks are simpler to get than mind scans and spinal faucets.
Maybe a very powerful element of the examine is that it confirmed the flexibility to measure adjustments in protein ranges years earlier than signs present. This presents hope that testing for Alzheimer’s with out signs is feasible and will sooner or later be a part of a routine screening, such as you would have for high cholesterol or diabetes.
The examine examined for a particular type of p-tau referred to as p-tau217. Bekris famous that there are numerous types of p-tau discovered within the blood, however p-tau217 is a promising biomarker as a result of it’s very excessive in individuals with Alzheimer’s illness. “One explicit p-tau217 check has obtained FDA approval and can probably be out there quickly commercially,” Bekris mentioned.
Checks for p-tau are nonetheless used solely in analysis at this level, however at the moment you will get a blood check for beta amyloid proteins as a threat evaluation device for Alzheimer’s. To get the check, it is advisable to have sure threat elements and to speak to your healthcare supplier in regards to the professionals and cons. If the check is best for you, they will write you a prescription.
Do you have to get a blood check for Alzheimer’s illness?
It’s vital to notice that the check is supposed to point out potential threat and doesn’t diagnose Alzheimer’s. It’s additionally not accepted by the FDA and isn’t at the moment coated by medical health insurance. As well as, some specialists have raised questions in regards to the accuracy of the beta amyloid protein check, noting that it may lead to false positives, which may trigger pointless anxiousness for individuals. Bekris famous that testing the blood or fluid for p-tau is extra correct than measuring the degrees of beta amyloid in blood however false positives are nonetheless doable. The hope is that blood checks can begin out as a device that results in extra analysis.
At present, a prognosis for Alzheimer’s comes from a number of outcomes from mind imaging, reminiscence checks and biomarker checks — amongst different elements.
Bekris mentioned the a number of diagnostic checks are higher collectively than alone. “This extra detailed analysis will rule out or rule in Alzheimer’s disease with the very best accuracy and is required earlier than the kind of Alzheimer’s remedy is chosen by each affected person and their physician,” she mentioned.
This 12 months has seen some vital developments in analysis. However there’s nonetheless no remedy for Alzheimer’s. We’re prepared for extra choices, treatments and options for this devastating mind illness.
