Novel AI Tool May help to Predict Alzheimer’s risk

Globally, around 50 million people have dementia and the total number is projected to reach 82 million in 2030 and 152 in 2050, according to the World Health Organization

A team of scientists, including one of an Indian-origin, has successfully trained a new Artificial Intelligence (AI) algorithm that may soon help doctors to make accurate predictions regarding cognitive decline leading to Alzheimer’s disease and provide intervention.

The team, from the McGill University in Canada, designed an algorithm that learns signatures from magnetic resonance imaging (MRI), genetics, and clinical data.

This specific algorithm can help predict whether an individual’s cognitive faculties are likely to deteriorate towards Alzheimer’s in the next five years.

“At the moment, there are limited ways to treat Alzheimer’s and the best evidence we have is for prevention. Our AI methodology could have significant implications as a ‘doctor’s assistant’ that would help stream people onto the right pathway for treatment,” Mallar Chakravarty, assistant professor at the University’s Department of Psychiatry.

“For example, one could even initiate lifestyle changes that may delay the beginning stages of Alzheimer’s or even prevent it altogether,” she added.

For the study, published in the journal PLOS Computational Biology, the team trained their algorithms using data from more than 800 people ranging from normal healthy seniors to those experiencing mild cognitive impairment, and Alzheimer’s disease patients.

“We are currently working on testing the accuracy of predictions using new data. It will help us to refine predictions and determine if we can predict even farther into the future,” Chakravarty noted.

With more data, doctors would be able to better identify those in the population at greatest risk for cognitive decline leading to Alzheimer’s.

Alzheimer’s disease, the most common form of dementia, may contribute to 60-70% of cases. Presently, there is no truly effective treatment for this disease. (IANS)

To help news industry use Artificial Intelligence (AI) in more innovative ways, Google has announced a partnership with Polis, the international journalism think-tank at London School of Economics and Political Science, to create “Journalism AI”.

Part of the Google News Initiative (GNI), the “Journalism AI” project will focus on research and training for newsrooms on the intersection of AI and journalism.

“As part of ‘Journalism AI’, next year, we’ll publish a global survey about how the media is currently using — and could further benefit from — this technology,” Google said in a statement on Friday as it organised GNI Innovation Forum here.

“We’ll also collaborate with newsrooms and academic institutions to create a best practices handbook and produce free online training on how to use AI in the newsroom for journalists worldwide,” informed Matt Cooke, Head of Partnerships and Training, Google News Lab.

After testing with partners over the last two years, Google also introduced a new tool called Google Earth Studio which is an animation tool for Google Earth’s satellite and 3D imagery.

The tool empowers graphics specialists with new ways to leverage Google Earth imagery for storytelling.

“We’re inviting newsrooms around the world to start using the product for the first time,” said Google.

According to the company, it has provided free training to journalists on a range of tools reaching more than 140,000 people in-person.

“Our training on Google tools for journalists are now available in 16 languages — including Indonesian Bahasa, Thai and Turkish,” said Cooke.

Google News in November launched a new innovation challenge to help scribes and publishers in the Asia-Pacific region produce quality journalism in the digital age.

The Asia-Pacific Google News Initiative (GNI) Innovation Challenge will fund selected projects up to $300,000 and finance up to 70 per cent of the total project cost, that inject new ideas into the news industry.

According to Google, in Asia-Pacific, journalists and publishers are increasingly grappling with questions over how quality journalism can thrive in the digital age.

“From Yangon to Manila, Sydney to New Delhi, they are experimenting with fresh approaches to reporting and new business models,” said the company. (IANS)
