British researchers believe they have found a way to diagnose Alzheimer’s early. A revolution that would greatly help those affected and perhaps end up finding a treatment for this disease.
A new, highly precise method for detecting Alzheimer’s
British scientists from Imperial College London have just developed a new method to detect Alzheimer’s disease at an early stage, the results and conclusions of which were published on June 20 in Nature Journal, Communication Medicine. In the columns of Daily Mailwe learn that a brain scan is part of it “a machine learning model” would make it possible to know in 98% of cases whether the patient suffers from Alzheimer’s disease or not.
In fact, it is an algorithm that is already being used in cancer research. It was tested on data from 400 patients already diagnosed with early or advanced Alzheimer’s and patients with other pathologies such as Parkinson’s. Another study was conducted at Imperial College Healthcare NHS Trust Hospital using information from 80 people who were still diagnosed with Alzheimer’s.
An algorithm identifies diseased parts of the brain
This system consists of a millimeter map of the brain divided into 115 regions and more than 600 features to be scanned (the size, shape and texture of each section), which are then sifted through during an MRI. This would make it easier for us to diagnose a brain disease in a patient, be it Alzheimer’s or another brain disease.

“Many patients presenting to clinics with Alzheimer’s also have other neurological disorders, and even within this group our system was able to distinguish patients with Alzheimer’s from those who did not.”explains Professor Eric Aboagye, who led the research, in a press release.
A scanner for “reading” brain regions
” Doctors could get a scan of a person’s brain that the machine learning system could read. In 98% of the participants’ brain scans, the system correctly identified a case of Alzheimer’s andYears almost 80% of scans were able to tell if the person had advanced or early stage Alzheimer’s disease ”we can read on the UK site.

“Currently, no other simple method can predict Alzheimer’s disease with this accuracy, so our research is an important step forward.”said Professor Aboagye.

“An algorithm for more information”
“Although neuroradiologists are already interpreting MRI scans to diagnose Alzheimer’s disease, it is likely that some features of the scans are not even known to specialists. Using an algorithm capable of selecting the texture and subtle structural features of the brain that could be affected by Alzheimer’s disease really improve the information we can get with standard imaging techniques” welcomes dr Paresh Malhotra, neurologist at Imperial College.
