BRUSSELS: Artificial Intelligence may diagnose dementia in a day

Published

on

BRUSSELS: Scientists are testing an artificial-intelligence system thought to be capable of diagnosing dementia after a single brain scan.

It may also be able to predict whether the condition will remain stable for many years, slowly deteriorate or need immediate treatment.

Currently, it can take several scans and tests to diagnose dementia.

The researchers involved say earlier diagnoses with their system could greatly improve patient outcomes.

Identify patterns

“If we intervene early, the treatments can kick in early and slow down the progression of the disease and at the same time avoid more damage,” Prof Zoe Kourtzi, of Cambridge University and a fellow of national centre for AI and data science The Alan Turing Institute, said.

“And it’s likely that symptoms occur much later in life or may never occur.”

Prof Kourtzi’s system compares brain scans of those worried they might have dementia with those of thousands of dementia patients and their relevant medical records.

The algorithm can identify patterns in the scans even expert neurologists cannot see and match them to patient outcomes in its database.

Memory clinics

In pre-clinical tests, it has been able to diagnose dementia, years before symptoms develop, even when there is no obvious signs of damage on the brain scan.

The trial, at Addenbrooke’s Hospital and other memory clinics around the country, will test whether it works in a clinical setting, alongside conventional ways of diagnosing dementia.

In the first year, about 500 patients are expected to participate.

Their results will go to their doctors, who can, if necessary, advise on the course of treatment.

Consultant neurologist Dr Tim Rittman, who is leading the study, with neuroscientists at Cambridge University, called the artificial-intelligence system a “fantastic development”.

“These set of diseases are really devastating for people,” he said.

“So when I am delivering this information to a patient, anything I can do to be more confident about the diagnosis, to give them more information about the likely progression of the disease to help them plan their lives is a great thing to be able to do.”

Sometimes struggling

Among the first to participate in the trial, Denis Clark, 75, retired from his job as an executive for a meat company five years ago.

Last year, his wife, Penelope, noticed he was sometimes struggling with his memory.

And they are now concerned he is developing dementia.

Denis tries to describe his symptoms but Penelope interjects to say he finds it hard to explain what is happening.

The couple are worried about having to sell their home to fund Denis’s care.

So Penelope is relieved they should not have to wait long for a diagnosis and an indication of how any dementia is likely to progress.

“We could then plan financially,” she said.

“We would know whether as a couple we could have a few holidays before things get so bad that I can’t take Denis on holiday.”

Mental problems

Another of Dr Rittman’s patients, Mark Thompson, 57, who began having memory lapses 10 months ago, before the trial of the artificial-intelligence system began, said it would have made a big difference to him had it been available.

“I had test after test after test and at least four scans before I was diagnosed,” he said.

“The medical team was marvellous and did everything they could to get to the bottom of what was wrong with me.

“But the uncertainty was causing me more… mental problems than any caused by the condition.

“Was it a tumour? Would they need to operate? It caused me so much stress not knowing what was wrong with me.”

CAIRO: Indian-Origin Teen, Son Of IIT-JEE Topper, Wins Gold At World’s Toughest Programming Contest

Published

on

CAIRO: Agastya Goel, a 17-year-old Indian-origin student from California, has won his second gold medal at the 36th International Olympiad in Informatics (IOI), which took place in Egypt. Agastya, son of Stanford professor Ashish Goel, secured the fourth overall rank at the prestigious contest, also dubbed as the world’s toughest programming competition for high school students.

Agastya scored 438.97 out of 600, while Kangyang Zhou of China topped the event with a perfect score of 600. A total of 34 students were awarded gold medals this year, including fellow Indian participant Kshitij Sodani, who ranked 21st.

This marks the 17-year-old’s second gold at the IOI. His father, Ashish Goel, made waves in 1990 by topping the IIT-JEE exam before going on to build a distinguished career at companies like Twitter and Stripe. 

Who is Agastya Goel?

Agastya Goel, a junior at Henry M Gunn High School in Palo Alto, California, loves physics, computer science, and music. His hobbies include tennis, hiking, stargazing, and playing the guitar and piano.

Agastya’s interest in physics began at a young age, with his father introducing him to the subject during car rides and hikes. One memorable experience was learning about projectile motion while playing Angry Birds. This sparked a fascination with physics that has only grown stronger over the years.

Agastya’s competitive spirit was ignited through the USACO competition series, which he started preparing for in 6th grade. His hard work earned him a spot at the USACO training camp in his freshman year, followed by selection for the US IOI team. 

Initially, Agastya considered majoring in computer science, but after exploring physics, he discovered a new passion. He spent 14 days intensively studying physics over winter break and was hooked.

CALIFORNIA: Indian-origin business leaders from the IT industry lauded Prime Minister Narendra Modi’s leadership for putting India on the global map as a “credible innovator and leader” for all nations to invest in and grow.

Speaking at the Indiaspora AI Summit 2024 on ‘Can Artificial intelligence be good force for future or not’ at the University of Stanford on April 26, Informatica CEO Amit Walia said, “India is perceived very differently in the global space. It’s a space of innovation. It’s a space of human capital. It’s a space of progress and innovation. And as we look forward, what Modi has been able to do is put India into the global map as a credible innovator, leader for all countries to invest in and grow.”

Speaking at the same event, Elastic CEO Ashutosh Kulkarni said that PM Modi and the government have been doing amazing work.

Mr Kulkarni said, “The Prime Minister and the government has been doing some amazing work and their focus on being open to innovation, their focus on industry, their focus on bringing the population, India is now one of the, it is the largest, most populous country in the world and bringing that population towards progress, the way they have tapped into the potential of this country has just been fantastic.”

Calling PM Modi’s era “amazing,” Mayfield Fund Managing Partner Navin Chaddha praised PM Modi’s leadership for ties between India and the US and his ability to connect the Indian diaspora which he stressed is doing extremely well in the tech industry. He noted that India is making progress in using technology and improving its infrastructure.

Navin Chaddha said, “The Modi era has been amazing, the kind of relationship they’ve been able to build with the United States. And to be able to connect the Indian diaspora, which is doing extremely well in the tech industry, hats off to them. And also the progress India is making in using technology, improving the infrastructure is just amazing. So, Mr Modi, keep doing what you’re doing.”

Rohit Jain, Speaker and Moderator – CIO, Harvard Business School, called on PM Modi to increase his guarantee, as he has always delivered. The event on Artificial Intelligence was organised to deliberate and discuss artificial intelligence.

He said, “Mr Modi needs to increase his guarantee because he’s always been delivering. So, I think his promises have been 100 per cent true. So, he now needs to promise 110 per cent and then again he’ll deliver on that. Mr Modi, thank you for what you have done, not only for India, but for the world.”

Priya Rajan, Managing Director, National Venture Coverage and Business Development, MUFG lauded PM Modi’s leadership in the entrepreneurial ecosystem. He stated that a number of VCs across the globe want to invest in India.

She said, “I see the Modi magic play is in the entrepreneurial ecosystem, which is an adventure ecosystem. So you can see the number of VCs now wanting to invest, not just where in India, investing in India, but world investors around the world wanting to do things. And you’re seeing kind of US, a ton of US global investors now setting up shops in India. I think that’s all coming back to what Modi magic has created.”

At the event, prominent Indian diaspora, along with the esteemed corporate leaders from the US shared their insights on the topic “Can Artificial Intelligence be a force for future or not.”

Rajya Sabha MP Satnam Singh Sandhu participated in the event. Notably, PM Modi has been advocating that artificial intelligence can provide a great support to help humanity’s development in the 21st century.

Taking to X, Satnam Singh Sandhu stated, “Indiaspora AI Summit, Stanford University, USA: Delighted to be a part of the summit where we had @ericgarcetti, US Ambassador to India, Indian Diaspora and business leaders from IT sectors who reiterated how PM @narendramodi Ji is leveraging AI to shape nation’s future strategy to build Viksit Bharat by 2047.”

“They highlighted PM Modi’s tech-savvy approach and his efforts to promote AI applications in various sectors like agriculture, health-care, and education for social development and inclusive growth. They also condemned the Western bias against India to rank them lower in parameters like Ease of doing business, and cite the irregularities while computing such rankings,” he added.

Earlier in December, PM Narendra Modi said that artificial intelligence is a dynamic issue and that India is working on creating a global framework for AI. He made the remarks while interacting with the participants of the Grand Finale of the Smart India Hackathon.

Speaking to the participants via video conferencing, the Prime Minister said, “AI (Artificial Intelligence) is a very dynamic issue. If one solution is brought in, the mischievous people will find another way. We have to be very alert to any new technology. It can be very useful if used within rules, but if it is used in the wrong way, it can create a lot of problems.”

“We all are aware of the generative AI-created deep fake videos that look completely real. Hence we need to be more alert before believing any photo or video. India is working on creating a global framework for AI,” said PM Modi.
