Might a easy blood check give individuals a warning about mind ailments years earlier than signs present up? Neurosurgeon Dr Jay Jagannathan just lately raised this query on Instagram, asking his followers: “Would you are taking this check if it may provide you with a warning signal years earlier than signs?”
In his put up, he highlighted the Neurofilament Gentle Chain (NfL) check as a possible game-changer. “Neurofilament gentle chain (NfL) — a marker of nerve cell harm — is rising as one of the highly effective predictors of mind well being. Elevated ranges are linked to Alzheimer’s, Parkinson’s, a number of sclerosis, stroke, and even traumatic mind harm.” What makes it vital, he defined, is that “you would really feel ‘advantageous’… however NfL can already be sounding the alarm. Why it issues: nerve cells don’t restore simply. Elevated NfL means silent however ongoing mind injury — lengthy earlier than signs seem.”
He additionally described how the check works: “What the check is: the serum/plasma NfL check is a straightforward blood draw. It measures tiny protein fragments (NfL) launched when mind or spinal twine cells are broken. Usually, these proteins keep inside neurons. When neurons are injured, they leak into the blood and spinal fluid, the place we are able to measure them.” In line with him, docs could use NfL traits as a pink flag or to trace illness development even earlier than an MRI picks up modifications.

Alongside this, Dr Jagannathan confused prevention, advising individuals to manage blood strain and blood sugar, sleep 7–8 hours, transfer every day, eat a Mediterranean-style eating regimen, keep away from smoking and extra alcohol, and handle stress. He concluded with a transparent reminder: “Mind injury is commonly silent — till it isn’t. Don’t look forward to signs. Ask your physician about NfL testing if you happen to’re in danger or have a household historical past of neurological illness.”
However, how dependable is that this marker in truly predicting circumstances like Alzheimer’s or Parkinson’s earlier than scientific indicators develop?
Dr Jagdish Chattnalli, senior minimal invasive mind and backbone surgeon, Bengaluru West Clinics, HCG Hospitals Bengaluru, tells indianexpress.com, “Elevated neurofilament gentle chain displays neuronal harm and is likely one of the most delicate blood markers now we have for ongoing mind injury. It’s notably helpful as a prognostic indicator as a result of increased ranges are constantly related to quicker decline or a better chance of conversion to symptomatic illness in a number of issues, together with Parkinson’s illness and Alzheimer’s-related syndromes.”
Nevertheless, he notes that NfL is just not disease-specific. “A raised worth tells us that neurons are being broken, but it surely doesn’t by itself establish the trigger or give a agency analysis. In follow, the perfect use of NfL is as a part of a broader evaluation that features scientific analysis, imaging, and different biomarkers.”
The NfL check is described as ‘a easy blood draw,’ however is that this check broadly obtainable, and will the final inhabitants think about it?
The assay itself is a simple blood check, Dr Chattnalli notes, and fashionable high-sensitivity platforms make it potential to measure very low ranges reliably. Industrial laboratories and reference centres now supply NfL testing, and validated assays can be found from main suppliers. That mentioned, routine inhabitants screening is just not the present follow. NfL testing is most useful when ordered by a clinician who can interpret the outcome alongside signs, imaging, and different checks.
“I’d advocate testing in individuals who have regarding signs or goal findings on examination or imaging, and in people with robust household historical past or different clear danger elements, the place understanding the trajectory of neuronal harm would change administration,” mentions the consultants.
