Artificial intelligence could be used to identify whether or not someone is feeling suicidal, a study has found.
Each participant was presented with three lists of ten words, reports MIT Technology Review - ten death-related words, ten words relating to positive concepts (e.g. “carefree”) and ten words related to negative ideas (e.g. “trouble”). Their brains were then scanned using an MRI.

The scientists used the AI programme to search the scans to see how the participants responded to the lists of words. The results showed that healthy patients and those with suicidal thoughts showed markedly different reactions. For example, when the suicidal participants were shown the word “death”, the “shame” area of their brain lit up more than it did in the control group.
Of the 34 participants, says Engadget, the system was able to identify those known to be “suicidal ideators” with an accuracy of 91%.
However, while the system could potentially be used to help people with suicidal thoughts, Wired warns, the small sample group may not accurately reflect the “broader population”.
AI technology is being developed by researches across the world in a bid to help the medical industry.
Earlier this week, researches from Showa University, in Yokohama, Japan, revealed a similar technology that can identify bowel cancer through a colonoscopy in “less than a second”.
