If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
Artificial intelligence (AI) could diagnose a suspected dementia patient the day they are assessed. The disease currently has no set test, with medics generally relying on cognitive assessments and brain scans. With it sometimes taking years to reach a diagnosis, scientists from the University of Cambridge are developing an AI system that could spot signs of the disease after a single brain scan. The system is "trained" to compare a suspected patient's brain scan against thousands of confirmed cases, with the algorithm potentially identifying signs of the disease that a neurologist could not spot. Although the technology is still in a trial stage, it could diagnose dementia years before symptoms emerge.
Researchers at Cambridge University in the UK are trialling an artificial intelligence system that they think could spot the signs of dementia after a single brain scan. The team – led by Prof Zoe Kourtzi of the university and Alan Turing Institute – told the BBC that the AI could make it possible to start treatment earlier to slow down progression of Alzheimer's disease and other forms of dementia. The technology could be used to spot patients who are likely to have a slow decline in cognition and memory, and those that could have more rapid progression. At the moment, it can take several brain scans and a battery of other cognitive tests to diagnose dementia, a process that can take between four and 12 weeks depending on waiting lists, according to the Alzheimer's Society. The AI has been trained using thousands of brain scans from patients with dementia patients, and uses an algorithm to identify patterns that even expert neurologists cannot see, according to the BBC report.
As supercomputers take on the mighty challenge of accelerating research in the complexities of life sciences, Artificial Intelligence (AI) is not far behind. Researchers are testing a system based on AI to detect neurological disorders like dementia in just one brain scan. As researchers begin the trial of the system, currently it takes several scans and tests to diagnose dementia. An earlier diagnosis of the disorder could be life-saving and enhance treatment strategies. The team of researchers from the University of Cambridge are hopeful that the AI system will be tested in a "real-world" clinical setting on about 500 patients, in its first year of trial.
Scientists at Cambridge University have developed an AI system that they believe could diagnose dementia from a single brain scan. Pre-clinical testing suggests the tech can spot signs of dementia years before symptoms develop. The system is now being evaluated in clinical trials. Attend the tech festival of the year and get your super early bird ticket now! This process can take between four to 12 weeks, according to the Alzheimer's Society.
AI can spot patterns in brain scans that even the most experienced neurologists can't see Scientists are testing an artificial intelligence system they believe could lead to a diagnosis of dementia following a brain scan. It can also predict whether the condition will remain stable for many years, worsen gradually, or whether the patient will require immediate treatment. Currently, a number of tests and CT scans are needed to diagnose dementia. Researchers involved in the study say that early diagnosis with the system they have developed can significantly improve patients' prognosis. "If we intervene earlier, treatments can act earlier and delay the progression of the disease, and at the same time, if we intervene earlier, can prevent further damage." of the Alan Turing Institute of Artificial Intelligence and Data Science.
Artificial intelligence has been employed in the fight against dementia by scientists who say it can diagnose the condition from a single scan of the brain. Currently in pre-clinical trials, the system has been able to diagnose dementia years before the first symptoms develop, even with no signs of damage on the scan. It currently takes multiple scans and tests to diagnose dementia, and by the time they are complete it may be too late to enact some of the remedies that can offset the condition, researchers from the Alan Turing Institute in Cambridge explained. The new system compares brain scans of those worried they might have dementia with scans from thousands of dementia patients to identify patterns. Being able to diagnose the condition early, even before any signs are visible on scans, will allow for lifestyle and medical interventions to delay the onset, according to the team.
It's been used to detect eye diseases, make medical diagnoses, and spot early signs of oesophageal cancer. Now it has been claimed artificial intelligence may be able to diagnose dementia from just one brain scan, with researchers starting a trial to test the approach. The team behind the AI tool say the hope is that it will lead to earlier diagnoses, which could improve outcomes for patients, while it may also help to shed light on their prognoses. Dr Timothy Rittman, a senior clinical research associate and consultant neurologist at the University of Cambridge, who is leading the study, told the BBC the AI system is 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."
If you thought that heart disease or cancer might be the leading causes of death in England and Wales, you'd be wrong. Dementia has become the leading cause of death and accounted for 12.8% of all deaths in the UK in 2018. It is the biggest health crisis in the UK and has huge financial implications: NHS England and Dementia UK have estimated that the cost associated with the disease is a staggering £23bn per year1. Dementia is an umbrella term used to describe symptoms that occur when the brain cells stop working. This happens when cells die or blood flow in the brain is restricted.
