New artificial intelligence system can detect Alzheimer’s disease early

Machine learning is a type of artificial intelligence that allows computer programmes to learn when exposed to new data without being programmed. Researchers coupled machine learning methods with a special magnetic resonance imaging (MRI) technique that measures the perfusion, or tissue absorption rate, of blood throughout the brain to detect early forms of dementia, such as mild cognitive impairment (MCI). “MRI can help with the diagnosis of Alzheimer’s disease. However, the early diagnosis of Alzheimer’s disease is problematic,” said Alle Meije Wink, from the VU University Medical Centre in Amsterdam. Scientists have long known that Alzheimer’s disease is a gradual process and that the brain undergoes functional changes before the structural changes associated with the disease show up on imaging results. Physicians have no definitive way of identifying who has…
