A study finds that artificial intelligence can predict Alzheimer's disease 6 years earlier than doctors
According to one study, artificial intelligence can be used to detect Alzheimer's disease six years before a patient is diagnosed normally.
Doctors used the self-learning computer to detect changes in brain scans that are too subtle for humans to see.
The system was able to identify dementia in 40 patients an average of six years before being formally diagnosed.
British AI expert Noel Sharkey of the University of Sheffield said of the findings: "This is exactly the kind of task for which deep learning is cut out: finding high-level patterns in the data.
"Although the sample sizes and test sets were relatively small, the results are so promising that a much larger study would be worth it."
Boffins of the University of California trained the computer with more than 2,100 scans of 1,002 patients.
Scans measure brain activity by tracking the absorption of a radioactive fluid injected into the blood.
Research has linked the development of Alzheimer's with particular changes in certain regions of the brain, but they can be difficult to detect.
The Alzheimer's algorithm was able to be taught to recognize patterns in brain scans that indicated disease.
As a final test, he received a set of 40 scans of 40 patients he had never studied before.
It was shown to be 100% accurate in the detection of Alzheimer's disease many years before the patient was subsequently diagnosed.
Dr. Jae Ho Sohn, who worked on the project, said: "We are very pleased with the performance of the algorithm.
"He was able to predict every case that progressed to Alzheimer's disease."
The early detection of Alzheimer's disease could open the door to new ways to slow down or even stop the progression of the disease.
Dr. Carol Routledge, of Alzheimer's Research UK, said: "Diseases that cause dementia start in the brain up to 20 years before symptoms start to appear, which gives us a vital opportunity to intervene before harm occurs. generalized
"This study highlights the potential of machine learning to help with the early detection of diseases such as Alzheimer's disease, but the results should be confirmed in much larger groups of people before we can adequately assess the power of this approach."
The research is published in the latest issue of the journal Radiología.
