Some patients diagnosed with schizophrenia might instead have a rare visual condition that can cause other people’s faces to appear “demonic”, authors of a case study argue.

The condition, called prosopometamorphopsia (PMO), can cause facial features to appear drooped, larger, smaller, out of position or stretched.
