Alzheimer's Clues May Appear Early: Study Claims Your Mid-40s Might Be The Time

Alzheimer's disease

Alzheimer's disease is a progressive neurodegenerative disorder that affects millions of people worldwide, and it has a long preclinical stage. It is mostly diagnosed at an advanced age, but according to doctors, it begins years before the symptoms become evident. New research shows that blood biomarkers, along with self-reported memory concerns, could give an explanation as to how Alzheimer's disease worsens over time. Therefore, the best time to nourish brain health is during your 40s or 50s.

For this study, researchers used data from the Dunedin Study at the University of Otago, which had been following a few participants for over 50 years. Researchers found a protein known as pTau181, which is associated with self-reported problems linked to memory and thinking skills. Participants were 45 years old at the time of assessment. Typically, an Alzheimer's diagnosis happens at or after the age of 65–70.

When it comes to Alzheimer's, the treatments could only slow down disease progression, but they do not fully restore cognitive function, which is usually lost in the advanced stages. Researchers noted that these treatments work best when taken early, which makes it important to identify the early signs of Alzheimer's disease.

Researchers noted that different types of dementia can look different at various stages of the disease. However, the course of progression and treatment can vary from patient to patient. In the past, Alzheimer's could only be diagnosed post-mortem or through invasive procedures such as lumbar punctures. However, researchers are now working towards identifying blood biomarkers that could offer minimally invasive ways to identify high-risk patients for Alzheimer's.

<h2>Can Alzheimer's be detected early?</h2>

Researchers note that Alzheimer's can be detected in the early stages, and this could provide an opportunity for prevention. It may also offer health benefits for ageing and the brain. Some lifestyle changes include supporting people to remain active, continue engaging in social activities, and address factors such as hearing loss or hypertension. Preventive approaches in this case have worked more effectively the sooner they are implemented. Therefore, it is important to study middle-aged populations, as the signs can start appearing long before the disease is finally diagnosed.

As people get older, they notice that their memory is not as strong as it used to be. Forgetfulness gradually becomes a common issue with advancing age. However, in some cases, these problems indicate a different story altogether. Recent research shows that minor changes in cognition often begin long before diagnosis, and that is the first moment the disease is truly felt.

<h2>Screening for biological Alzheimer's markers</h2>

When it comes to screening for biological markers, combining them with subjective memory function reports can help distinguish the earliest signs of Alzheimer's from normal ageing. Proteins such as pTau181 are much higher in Alzheimer's patients, but researchers have not yet ascertained when they begin to accumulate. While researchers did not find that pTau181 was linked to MRI scans measuring cognitive test performance at 45, there were two possible explanations for this:

<ol><li>pTau181 might increase during the early stages of Alzheimer's, when people start to experience worsening memory, but it does not appear on an MRI.</li><li>Alternatively, it could be that high pTau181 is not linked to Alzheimer's risk in midlife, but the protein could still be useful for Alzheimer's diagnosis in older adults.</li></ol>
