Artificial Intelligence may detect dementia after single scan

August 10, 2021 | 3 minutes read

Scientists are testing the  system  based on artificial intelligence which might be able to detect dementia after a single brain scan.

The researchers say that with  the help of  Artificial Intelligence (AI) tools the earlier diagnoses of dementia  could help in improving patients’ outcomes. And in the near future it may help to shed light on a patient’s prognoses too.

What would it be able to detect?

It may also be able to detect whether the condition will remain stabilised and for how many years. Or the patient needs immediate treatment or the condition will slowly deteriorate. 

For now it takes several tests and scans to diagnose dementia. If this technology is generated correctly it might be useful in the identification of pattrens  in the scans that even the expert neurologists cannot perceive.

This technology scans the brain and then matches the scans with the patient’s scan already present in the database. 

The Cambridge University and the fellow of the national centre for data science Professor Zoe Kourtzi at AI at Alan Turning Institute said:

“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.”

Neurologist Consultant Dr TimRittman the lead scientist of this study at Cambridge University termed this as a  “fantastic development”.

Furthermore he said:

“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.”

Pre-Clinical Trials:

In the Pre-Clinical trials the AI technology was able to diagnose dementia years before the development of symptoms.The Addenbrook’s hospital and other memory clinics around the UK will test this technology for further assurance. And for seeing whether this technology is able to work with the conventional or traditional  way of diagnosing dementia.

Also in the first year approximately 500 people  are expected to participate in the trails. The results of the test will go to doctors, or to the personnel who can advise them about the treatments and medications.

How AI is facilitating medicine now?

For now AI has been used in the detection of  eye diseases, spotting early signs of oesophageal cancer.Now, in near future it will be able to diagnose the early signs of dementia on brain scams. However,rightnow some experts are arguing not to expect very much. As Prof. Clive Ballard, the dementia expert at the University of Exeter said

“This approach is definitely a positive direction of travel that will lead to improvements in diagnosis, but we need to be really careful not to create false expectations.”
