June is Alzheimer’s and Brain Awareness Month.
Alzheimer’s illness is ruthless. It will possibly rob you of your reminiscence, persona and the power to do easy issues like swallow or converse.
Even scarier: Nearly 2 out of three individuals with Alzheimer’s are ladies or individuals assigned feminine at beginning.
However there’s excellent news within the screening developments for Alzheimer’s. There are actually blood exams that may assess your danger degree for Alzheimer’s — and you may get one proper now. However must you?

Blood check for Alzheimer’s
There are two varieties of exams 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 exams work higher than others,” stated Lynn M. Bekris, Ph.D., principal investigator on the Cleveland Clinic’s Lynn Bekris Lab. “The brand new blood exams 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 establish and assist diagnose Alzheimer’s illness.
This implies a blood check could possibly change the extra invasive process with out compromising outcomes. And blood exams are simpler to get than mind scans and spinal faucets.
Maybe an important element of the examine is that it confirmed the power to measure adjustments in protein ranges years earlier than signs present. This provides hope that testing for Alzheimer’s with out signs is feasible and will in the future 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 various 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 specific p-tau217 check has obtained FDA approval and can possible be obtainable quickly commercially,” Bekris stated.
Assessments for p-tau are nonetheless used solely in analysis at this level, however at the moment you may get a blood check for beta amyloid proteins as a danger evaluation instrument for Alzheimer’s. To get the check, you have to have sure danger components and to speak to your healthcare supplier concerning the professionals and cons. If the check is best for you, they will write you a prescription.
Must you get a blood check for Alzheimer’s illness?
It’s necessary to notice that the check is supposed to indicate potential danger and doesn’t diagnose Alzheimer’s. It’s additionally not authorized by the FDA and isn’t at the moment lined by medical health insurance. As well as, some specialists have raised questions concerning the accuracy of the beta amyloid protein check, noting that it might lead to false positives, which might trigger pointless nervousness 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 potential. The hope is that blood exams can begin out as a instrument that results in extra analysis.
At present, a prognosis for Alzheimer’s comes from a number of outcomes from mind imaging, reminiscence exams and biomarker exams — amongst different components.
Bekris stated the a number of diagnostic exams 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 therapy is chosen by each affected person and their physician,” she stated.
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.
