For families touched by Alzheimer’s disease, the journey is often filled with uncertainty and a deep desire for answers. The slow progression of cognitive decline can be a heavy burden, leaving many to wonder if there was anything they could have done sooner. Fortunately, cutting-edge testing methods are emerging, offering hope for earlier and more accurate risk assessment.

By understanding your potential risk earlier, you and your family can make informed decisions, explore preventative strategies, and approach the future with greater clarity and peace of mind. 

Let’s explore some of the most promising new tests for Alzheimer’s risk, explaining how they work and what they mean for you and your loved ones. Our goal is to demystify these complex topics, providing clear, compassionate information to support you on your wellness journey.

Understanding the Shift in Alzheimer’s Detection

For decades, a definitive Alzheimer’s diagnosis could only be confirmed after death through a brain autopsy. The tools available to the living were limited, often relying on cognitive assessments that could only identify the disease once significant symptoms had already appeared. This late-stage detection left little room for interventions that could slow progression or preserve brain function (1).

Today, researchers have identified key biomarkers that can indicate the presence of Alzheimer’s-related changes in the brain long before memory loss becomes apparent (2). This has paved the way for a new generation of tests that are less invasive, more accessible, and remarkably precise. These innovative methods are moving us from a reactive to a proactive model of care to personalized strategies for brain health.

Breakthroughs in Early Alzheimer’s Testing

Let’s explore some of the most significant advancements in Alzheimer’s testing that are bringing new hope to families worldwide.

Neurofilament Light Chain (NfL): A Window into Brain Health

One of the most exciting developments is the use of Neurofilament Light Chain (NfL) as a biomarker.

• What is it? Neurofilaments are proteins that form the internal “scaffolding” of neurons (nerve cells). When neurons are damaged or die—a hallmark of neurodegenerative diseases like Alzheimer’s—these proteins leak into the cerebrospinal fluid and, in smaller amounts, into the bloodstream.
• How is it measured? A simple blood test can now measure the levels of NfL. Elevated levels can indicate that neurodegeneration is occurring, acting as an early warning sign (3).
• Why is it important? It’s less invasive and more accessible than traditional methods like spinal taps. While high NfL is not exclusive to Alzheimer’s (it can be elevated in other neurological conditions), it helps doctors understand the rate of neurodegeneration and can be used to monitor the effectiveness of future treatments.

Apolipoprotein E (APOE4): Understanding Genetic Risk

Genetics play a role in Alzheimer’s risk, and understanding your genetic makeup can be an empowering step.

• What is it? The apolipoprotein E (APOE) gene provides instructions for making a protein that helps transport cholesterol in the bloodstream. It comes in several different forms, with APOE4 being the strongest known genetic risk factor for late-onset Alzheimer’s disease.
• How is it measured? A simple blood or saliva test can identify which APOE alleles you carry. Everyone inherits one copy from each parent. Having one copy of the APOE4 allele increases your risk, and having two copies increases it even further (4).
• Why is it important? It’s crucial to understand that carrying the APOE4 allele does not mean you will definitely develop Alzheimer’s. Many people with it never do, and many who develop Alzheimer’s do not have it. However, knowing your APOE4 status can be a powerful motivator for adopting brain-healthy lifestyle changes. For those at higher genetic risk, focusing on diet, exercise, sleep, and stress management becomes even more critical as a preventative strategy.

Creyos Health: Assessing Cognitive Function with Precision

While biomarkers look at the biology of the brain, it’s also important to measure how the brain is actually functioning. This is where advanced cognitive assessment tools come in.

• What is it? Creyos Health is an innovative platform that offers a suite of engaging, game-like cognitive tests. These assessments go beyond simple memory recall, measuring multiple domains of brain function, including attention, reasoning, and verbal ability.
• How does it work? The tests can be completed online in about 15-20 minutes. The platform provides a detailed report that compares your cognitive performance to others in your age group, helping to identify subtle changes that might not be noticeable in daily life.
• Why is it important? Early cognitive changes in Alzheimer’s are often subtle and can affect more than just memory (5). Traditional “pen-and-paper” tests can be time-consuming and may not be sensitive enough to detect these early signs. Creyos offers a scientifically validated, objective, and accessible way to track your cognitive health over time. Regular assessments can establish a personal baseline, making it easier to spot any changes early.

A Holistic Path Forward

These cutting-edge tests—NfL, APOE4, and Creyos—are powerful tools, but they are most effective when viewed as part of a comprehensive, holistic approach to health. At hol+, we believe in integrating the best of scientific innovation with the wisdom of time-honored wellness practices.

With the support of our integrative healthcare team, you can creative a personalized and holistic plan that may include (6,7):

• Nutritional strategies to support brain health.
• Targeted exercise programs to improve blood flow and cognitive function.
• Stress management techniques like meditation and mindfulness.
• Optimizing sleep to allow the brain to repair and consolidate memories.

This integrative model ensures that we are not just looking at a single data point, but at the whole person—mind, body, and spirit.
