People who are born blind never have schizophrenia.As a paper just published in
Frontiers in Psychology points out, congenital and early blindness appears to protect against schizophrenia. As the authors note, “across all past papers, there has not been even one reported case of a congenitally blind person who developed schizophrenia.” However, this is not so with blindness developed later in life. The authors conclude that it must be brain changes that occur secondarily to congenital and early blindness�"not blindness itself�"that protect against schizophrenia. They then go on to give an account of what those changes may be.
