The way we speak could be a sign of future Alzheimer's disease, according to artificial intelligence

This method was able to predict progression from mild cognitive impairment (MCI) to Alzheimer's disease within six years with 78.5% accuracy.

We still don't know exactly what it is. Alzheimer's disease But we know very well how the symptoms appear, and there are improvements in early detection every day.

in this meaning Come the most recent Advances in Artificial Intelligence (AI)which relates to the way we communicate verbally.

world of Boston University you have a new one Artificial Intelligence Algorithm developed speech patterns of people with mild cognitive impairment (MCI) Analyzed.This was able to do that. Progression from CCL to Alzheimer's disease within six years with 78.5% accuracy Percentage to predict.

How did they use artificial intelligence to predict Alzheimer's disease?

The study follows previous research by the same team, in which the authors used audio recordings of more than 1,000 people. Model training which accurately detects cognitive decline Could you.

The new algorithm was created using Audio recordings of 166 people with CCL aged 63 to 97 years He trained for years. Because the team already knew who had Alzheimer’s, they were able to use machine learning to find signals in written speech that linked 90 people who would have a decline in cognitive function to Alzheimer’s.

Alzheimer's, Artificial Intelligence
If you can predict what will happen, you have more opportunities and time to intervene.

as soon as algorithm It is trained, and can be used in reverse: it is Try to predict the risk of developing Alzheimer's disease using transcripts of speech sampleswhich had not been addressed before. Other important factors, such as age and gender, were added to obtain a final predictive value.

You can have it Think of value as the probability that someone will remain stable or develop dementia.“Explains Ioannis Paschalidis, a computer scientist at Boston University,”We wanted to predict what would happen in the next six years.“We found that we could make this prediction with relatively high confidence and accuracy. This shows the power of artificial intelligence,” he added.

The importance of early detection

One might of course wonder what the benefit of early detection is when there is no cure yet and the end result is always the same. Current treatments can partially help control Alzheimer's disease. However start earlier.

Early detection provides more opportunities to study the disease and its progression, and on this basis to develop effective treatment. People who are likely to develop Alzheimer's disease can participate in clinical trials early.

According to experts This approach has many positive aspects if it can be developed.It is the type of test that can be done quickly and inexpensively, even at home and without special equipment. It does not require injections or samples, just registration, and in the future it could be done via a smartphone app.

If you could predict what would happen, you would have done it. More options and time to intervene with medication “At least try to keep the condition stable and avoid moving on to more serious forms of dementia,” says Paschalidis.
