Alzheimer’s is a degenerative disease. that there is no cure. However, early detection may give patients more therapeutic options. For this reason, scientists focus their studies on how to detect this pathology when There’s still time to delay its effects,
one of the symptoms of alzheimer’s language impairment, which affects 60–80% Dementia patients. Earlier, researchers at Boston University had already developed a program for iDiagnose Alzheimer’s With Voice Recording And through artificial intelligence, but now another scientific group has gone a step further.
Using Modern AI Software chatgptResearchers at America’s Drexler University have succeeded in making it Able to detect early signs of Alzheimer’s Such as hesitation in speaking, errors in grammar and pronunciation, or forgetting the meaning of words. study Published in ‘PLOS Digital Health’.
chatgpt It is a model that is used, among other things, to generate human-like responses. Now the Drexler scientists have shown that their third generation, GPT-3, is able to identify these clues in spontaneous speech and Detect Alzheimer’s with 80% accuracy.
GPT-3 successful in predicting early stages of dementia After being trained by researchers, because it is an AI that learns after processing a large amount of information. It was taught using massive data sets from interviews with Alzheimer’s patients, for example extract speech patterns Of these people.
In addition, GPT-3 was also trained with voice recordings to detect the appropriate word usage for sick patients. After several training sessions, this AI was already an “Alzheimer’s detection machine”, as they describe it. Drexler University.
To test whether it worked, the scientists asked GPT-3 that will review dozens of interview transcripts and decide whether each one was manufactured by someone who developed Alzheimer’s. And the results were very positive: “Our results show that the embeddings of the text, generated by GPT-3, can be used reliably not only to detect people with Alzheimer’s disease from healthy controls, but also to predict the subject’s cognitive test scores, both based solely on speech data,” the authors wrote in the study.
Looking ahead, American scientists want Take advantage of these “promising results” for develop a web application To pre-select people who may have early onset dementia. This device can be used both at home and in the doctor’s office.
