This AI can only diagnose dementia through a brain scan

This AI can only diagnose dementia through a brain scan

Researchers at the University of Cambridge have developed an AI-based system that uses a single method to diagnose dementia rather than current methods.

Researchers at the University of Cambridge have developed an artificial intelligence-based system that they believe can diagnose dementia from a brain scan.

So far, the process of trying to find out if a patient has dementia has been very complicated. It often lasts for several weeks and the patient undergoes several cognitive tests as well as several brain imaging tests; Failed to achieve a definitive result every time.

On the other hand, the system proposed by Cambridge researchers requires only one image to make AI better: identifying characteristic patterns, but too abstract or complex for humans. This makes it possible to get an accurate result very quickly; Key data on the management of these diseases.

In fact, many dementia symptoms can experience dramatic development as soon as they begin; When diagnosed early, treatment can be more effective. This system also provides added value because it can also generate prognosis during illness.

AI, the expected revolution in diagnostic science

Naturally, when it comes to health, the results should be taken with a grain of salt. AI has been making revolutionary changes in diagnostic science for some time, but we are not yet ready to fully believe it; At this point, it is imperative that the man stay in the loop. And for good reason: although the AIs in this game are better than ours, they are not wrong. They rely entirely on a trained dataset. So it is It is impossible to get absolute certainty By this method.

But this does not mean that AI has no place in this field. This technology has recently entered the clinical trial phase; To assess its effectiveness, approx 500 British patients This device should be tested in the coming year. In particular, it allows for very clear conclusions to be drawn Accuracy level This technique. If found accurate enough, it can be a great diagnostic tool; Definitely enough to find a chosen place in neuropsychiatry and geriatrics. Incidentally, this is a new example of AI’s capabilities applicable to health, which can revolutionize our health care system much faster than we think.
