Artificial intelligence drastically reduces sequelae after a stroke

Far from Terminator clichés, artificial intelligence is saving lives in the UK. On Tuesday, the UK Department of Health announced a tripling of patients with little or no after-effects after a stroke, thanks to the use of artificial intelligence (AI).

The Brainomix e-Stroke system, developed by an English company based in Oxford, reduces the diagnosis by more than an hour and allows the most suitable treatment to be quickly selected under the supervision of a doctor. Its use, in 111,000 cases of suspected stroke, rose from 16% to 48% of patients with no or mild disability.

“Dramatic” improvement

AI provides decision support in the interpretation of brain scans, to allow the patient “to receive the right treatment, in the right place, at the right time”, emphasizes the ministry. More than 85,000 people in England have a stroke each year.

The Ministry of Health cites the example of Carol Wilson, teacher’s assistant and grandmother, who in June 2021 suffered from intense convulsions and rapidly lost sight and use of her limbs. The software made it possible to quickly diagnose a blood clot in the brain and to choose a thrombectomy. “I was able to sit up and text family the same day, go home and walk again about two days after a stroke,” the patient testified.

“Every minute saved during the initial in-hospital assessment of people with stroke symptoms dramatically improves a patient’s chances of leaving the hospital well,” Dr. Timothy Ferris, Director of NHS Transformation.
