These terrifying images are what it's like to have extraordinarily rare condition 'demon face syndrome'

Long misdiagnosed as schizophrenia, the details of what a patient actually sees while enduring 'demon face syndrome,' or prosopometamorphopsia, has long remained a mystery — until now. But a rare individual with the condition, a 58-year-old male who reached out to neuropsychologists at Dartmouth, has the unique ability to see faces normally on paper and on screens, despite seeing more eerie 'demon faces' in his real life. 'Most of the articles about PMO have been brief case reports about individual cases,' Dartmouth Professor Brad Duchaine told DailyMail.com, 'written by the neurologists who happened to encounter them in their clinical practice.' A rare individual with a variation of the 'demon face syndrome' has the unique ability to see faces normally on paper and on screens, despite seeing more eerie 'demon faces' in his real life. The divide allowed researchers to properly illustrate, for the first time, what faces look like to a person living with the demon-tinted glasses of prosopometamorphopsia Damage that led to PMO was often found in the form of lesions on the occipital and temporal lobes in the back of the brain, near areas that neuroscientists have classified as face-recognizing areas, marked in green above.
