Diagnosis comes when the changes show. The years before it are yours to use.
Alzheimer's is diagnosed when cognitive changes have become noticeable enough to evaluate. The biology can begin 15 to 20 years earlier. BetterBrain does not diagnose Alzheimer's. It is built for that earlier window: understanding your risk, establishing a baseline, and improving the parts of brain health you can influence.
A picture built from several pieces, not one test.
A clinician usually starts with what has changed: memory, navigation, repeated questions, medications, finances, work, or other daily tasks. A short cognitive test may follow, then blood work, brain imaging, and sometimes biomarkers. These pieces are interpreted together. A biomarker is not a diagnosis by itself, and a cognitive score is not a diagnosis by itself.
Diagnosis is the job of a clinician. BetterBrain focuses on the years when you may still feel well but want to understand your brain health and take action earlier.
What brought you here?
Three ways in, one page. Pick the one that sounds like you.
Early information is most useful when you can act on it.
Alzheimer's-related pathology can become detectable years before symptoms, but detecting pathology is not the same as diagnosing dementia. What matters is the context around a result: cognition, vascular health, metabolic health, family history, and the factors you can still change.
See everything we test ↗You do not have to wait for memory loss.
Alzheimer's-related changes can begin 15 to 20 years before memory problems become obvious. That can sound frightening, but it also means a long stretch when you may feel completely well and have time to work on the factors associated with long-term brain health.
Know how you are performing today, so there is something real to compare against later. Pair it with your blood pressure, ApoB, blood sugar, insulin, B12, homocysteine, and inflammation.
The 14 modifiable risk factors in the 2024 Lancet Commission are population-level, not a checklist to attack at once. High ApoB and insulin resistance call for a different plan than untreated hearing loss and poor sleep.
Fitness, sleep, metabolic health, hearing, nutrition, and cardiovascular health do not have to wait for a diagnosis. Decide, too, whether genetic or Alzheimer's biomarker testing would change your plan.
The biology can start long before the symptoms.
Alzheimer's-related changes can begin 15 to 20 years before memory problems become obvious. Newer blood biomarkers such as pTau-217 can help detect that pathology years before symptoms appear. What a result cannot tell you is why one person with that pathology stays cognitively healthy for years while another develops symptoms.
See what BetterBrain tests ↗Know what each test can tell you.
A cognitive score and an Alzheimer's biomarker answer different questions. Neither one is a diagnosis by itself.
BetterBrain does not treat pTau-217 as a standalone answer. It is an optional add-on to a broader assessment: a cognitive baseline, 50+ brain-relevant biomarkers, family and health history, and a Brain Health Coach who helps turn it into a prioritized plan.
Information is one input. The plan is the product.
BetterBrain does not hand you a number and wish you luck. Every result is read inside a system built to explain what it means for you, and where you can take meaningful action.
There is more to brain health than one test.
Up to 45% of dementia cases are potentially preventable, according to the 2024 Lancet Commission, which identified 14 modifiable risk factors across life. The useful question is where your own margin lies.
Review the evidence ↗Clear answers, without false certainty.
Can BetterBrain diagnose Alzheimer's?
No. BetterBrain does not diagnose Alzheimer's disease. If you are having cognitive symptoms, you should seek a clinical evaluation.
Can a blood test diagnose Alzheimer's?
A blood biomarker can provide evidence that Alzheimer's-related pathology is present, but it is interpreted as part of a broader clinical picture.
What is the first test for Alzheimer's?
Usually a clinical history and cognitive assessment, often followed by blood work and, when appropriate, imaging or biomarker testing.
What can I do if Alzheimer's runs in my family but I have no symptoms?
Establish a cognitive baseline, know your cardiovascular and metabolic numbers, address hearing and sleep, stay physically active, and decide whether genetic or Alzheimer's biomarker testing would change your plan.
You do not need a diagnosis to know where to start.
BetterBrain does not diagnose Alzheimer's. It gives you a cognitive baseline, 50+ brain-relevant biomarkers, and a Brain Health Coach to build a personalized action plan, ranked by impact, while you still feel well.
