New Study Is Close to Finding an Accurate Test for Diagnosing Alzheimer’s Disease

Alzheimer’s disease is a fatal neurodegenerative disorder that affects mainly people in their senior age bracket. Some people may also develop the brain ailment in their early age. In such a situation, the condition is termed at early onset dementia.

One of the leading problems with Alzheimer’s disease is that it hard to diagnose. This makes it challenging for doctors to start a patient’s medication and other care procedure, which help manage a patient’s symptoms. The recent study, however, looks promising and may have a solution for early diagnosis of Alzheimer’s disease, the most common type of dementia.

Current Tests for Alzheimer’s Diagnosis

There are very few ways of accurately diagnosing this brain condition. Of these, the prominent ways of testing are CT scans and MRI. These tests help doctors to rule out other conditions that may show similar symptoms.

Another test for diagnosing this brain condition is by collecting cerebrospinal fluid. The fluid is then checked for biomarkers of the disease. So far, this is the most accurate test for Alzheimer’s disease. However, it is costly.

Findings of The Research

This research published in the journal Alzheimer’s and Dementia was conducted by researchers from the Brigham and Women’s Hospital in Boston, MA. They have been working on developing a blood test for Alzheimer’s, which is accurate, cost-effective, and less invasive than collecting cerebrospinal fluid.

The researchers noticed that a common factor in Alzheimer’s and dementia is the formation of toxic plaques. These appear due to the accumulation of tau proteins, which are made of related molecules with somewhat different properties.

As per this study, the researchers have worked on preparing a method that identifies the specific subset of tau molecules that appear at high levels of Alzheimer’s.

The researchers looked for ways of detecting different tau molecules in both cerebrospinal fluid and blood. They tested the methods in plasma samples and cerebrospinal fluid among two classes of participants.

The results were promising. However, there is further validation that is required. The study author, Dominic Walsh, also added, “Our test will need further validation in many more people, but if it performs as in the initial two cohorts, it would be a transformative breakthrough.”

Moving Forward – How to Keep Yourself Save from Alzheimer’s?

Alzheimer’s disease is a degenerative disorder of the brain with no cure so far. It is mainly a disease of the elderly and controlling several risk factors can help reduce the risk of the brain ailment.

Some ways to limit the odds include maintaining a healthy weight, exercising regularly, sleeping well, and eating healthily. If you are not sure about what to eat, try to follow the Mediterranean diet, which is great for your brain health.

Alternatively, you can also follow the MIND diet, which has been chalked out to promote optimal health of the brain as well. Moreover, maintain a healthy social life and keep yourself mentally challenged to keep your brain active. This helps reduce the risk of Alzheimer’s disease.
