Motherboard stories on the potential explanations for why folks born blind are protected against schizophrenia: Over the previous 60-some years, scientists all over the world have been writing about this thriller. They’ve analyzed previous research, combed the wards of psychiatric hospitals, and regarded by businesses that deal with blind folks, looking for a case. As time goes on, bigger information units have emerged: In 2018, a examine led by a researcher named Vera Morgan on the College of Western Australia checked out practically half 1,000,000 youngsters born between 1980 and 2001 and strengthened this destructive affiliation. Pollak, a psychiatrist and researcher at King’s Faculty London, remembered checking within the psychological well being facility the place he works after studying about it; he too was unable to discover a single affected person with congenital blindness who had schizophrenia. These findings counsel that one thing about congenital blindness might defend an individual from schizophrenia.

A myriad of theories exist as to why — from the blind mind’s neuroplasticity to how imaginative and prescient performs an vital position in constructing our mannequin of the world (and what occurs when that course of goes fallacious). Choose researchers imagine that the ties between imaginative and prescient and psychotic signs point out there’s one thing new to study right here.
