Cambridge team says AI could diagnose dementia with one scan

#artificialintelligence 

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.
