As part of a trial, researchers have developed a phone test to spot early signs of Alzheimer’s.
In order to detect Alzheimer’s disease as early as possible and to manage it, preventive tests are a decisive advantage. Moreover, researchers around the world are trying to develop innovative solutions to detect it 100%. In the space of a few months, the innovations multiplied.
Several articles had highlighted the fact of detecting the disease with a blood test or by taking a selfie on your smartphone. Today, technology is still at the center of a innovation in the detection of Alzheimer’s. A team from Mass General Brigham has developed a phone test. And the latter, even if it does not allow screening, would make it possible to identify people at risk.
Their study on the subject was published in the Journal of Alzheimer’s Disease.
A three-spot phone test for ever earlier screening
For this experiment, the researchers worked closely with the Center for Alzheimer’s Research and Treatment. Among other things, the establishment has developed and validated the various tests used to highlight potential patients at risk. And the most conclusive only takes a few minutes and can be done on a smartphone.
In concrete terms, patients must perform three seemingly simple tasks. First, they must renew a prescription for a drug. Secondly, they must make a call with a specific instruction. Lastly, the volunteers must carry out a banking transaction.
At the same time, the researchers observed the cerebral activity of the volunteers during the tests. However, they noticed suspicious elements in patients who did not suffer from cognitive disorders. Indeed, they observed “signs of amyloid and elevated levels in their brain”.
In addition, the researchers observed difficulties in some volunteers performing tasks. In this, the test might allow better follow-up and early treatment.
When will it be generalized and accessible to the general public?
Currently, the test is not accessible. It is still in the development phase and will be the subject of additional studies in the coming months. However, one of the lead authors of the study is confident regarding its usefulness in the future, especially in people with no history.
“Although these results are preliminary, they signal that there is an association between an objective measure of instrumental activities of daily living and the interaction of tau and amyloid in a sample of cognitively normal older adults.”
