ALZHEIMER’S PREDICTION MAY BE FOUND IN CREATING TESTS

alzheimer’s prediction writing tests Is it possible to predict who will create Alzheimer’s disease simply by taking a look at writing patterns years just before there are symptoms?

According to a brand new study by IBM scientists, the answer is yes.

Plus, they and others say that Alzheimer’s is just the beginning. People with a multitude of neurological illnesses have unique language patterns that, researchers suspect, may serve as earlier warning signs of their diseases.

For that Alzheimer’s study, the scientists looked at a group of 80 women and men in their 80s — fifty percent had Alzheimer’s and the other people did not. But , seven . 5 years earlier, all have been cognitively normal.

The women and men were participants in the Framingham Heart Study, a long-running federal research effort that needs regular physical and intellectual tests. As part of it, these people took a writing check before any of them got developed Alzheimer’s that requires subjects to describe a sketching of a boy standing on a good unsteady stool and achieving for a cookie jar on the high shelf while a female, her back to him, will be oblivious to an overflowing kitchen sink.

The researchers examined the particular subjects’ word usage having an artificial intelligence program that will looked for subtle variations in language. It identified 1 group of subjects who were a lot more repetitive in their word utilization at that earlier period when all of them were cognitively normal. These subjects furthermore made errors, such as punctuational words wrongly or wrongly capitalizing them, and they utilized telegraphic language, meaning vocabulary that has a simple grammatical framework and is missing subjects plus words like “the, ” “is” and “are. ”

The members of that team turned out to be the people who created Alzheimer’s disease.

The. I. program predicted, along with 75 percent accuracy, who does get Alzheimer’s disease, according to results released recently in The Lancet record EClinicalMedicine.

“We had simply no prior assumption that phrase usage would show everything, ” said Ajay Royyuru, vice president of healthcare and life sciences study at IBM Thomas L. Watson Research Center within Yorktown Heights, N. Con., where the A. I. evaluation was done.

Alzheimer’s scientists were intrigued, saying that whenever there are ways to slow or prevent the illness — a goal that will so far remains elusive — it will be important to have basic tests that can warn, in early stages, that without intervention an individual will develop the progressive mind disease.

“What is going on the following is very clever ” mentioned Dr . Jason Karlawish, a good Alzheimer’s researcher at the College of Pennsylvania. “Given a huge volume of spoken or composed speech, can you tease out there a signal? ”

For years, scientists have analyzed speech plus voice changes in people who may have symptoms of neurological diseases — Alzheimer’s, ALS, Parkinson’s, frontotemporal dementia, bipolar disease plus schizophrenia, among others.

But , stated Dr . Michael Weiner, which researches Alzheimer’s disease on the University of California, Bay area, the IBM report fails new ground.

“This could be the first report I have noticed that took people who are not out of the ordinary and predicted with some precision who would have problems many years later, ” he stated.

The hope is to prolong the Alzheimer’s work to get subtle changes in vocabulary use by people with simply no obvious symptoms but that will go on to develop other nerve diseases.
