Blindness Completely Protects Against Schizophrenia; Here’s Why 

You’ve probably noticed this video is a little different from the usual stuff I do. Please tell me if you like this more/less and I will happily oblige :)

My brother had paranoid Schizophrenia before he died and i think this is a really interesting theory. He needed glasses and the prescription for the right lens and the left were really different.

that’s crazy that its so common i had no idea

Any literature or studies on the incidence of schizophrenia in deaf people? That would be an interesting related idea

Let me drop this Nash Style With the following 5 words this man is a genius! The brain is essentially a "prediction machine" that is constantly busy comparing new inputs from the environment with predictions generated by internal models of the brain. This is the only way the human brain is able to adapt to ever-changing situations and grasp new environments. Now, if blind, visual perception no longer occurs. Imagine hearing voices, compared with somebody being able to see and to check where this comes from, thus avoiding recognition of audible but undetectable voices. It is only acoustic stimuli that have been supplied for the comparative models to be created for blind people in their internal Memory. Consequently, there will be a contradiction which will only exist in the case of having both the auditory and the Visual sensory pathways available to handle corresponding stimuli. The prediction machine compares the different perceptions of sight as well as hearing to come independently to the conclusion this is a new situation and adaptation is necessary, so it corrects this prediction according to our perceived reality, The Brain has become the cause of a flawes perception, our environment is now distorted and further comparisons will take place with the already distorted internal models. The Blind person does not know this state, which we probably perceive as a loss of reality for another Person...

I was diagnosed with a personality disorder with schizotypal traits. I also find it difficult to process/filter sounds, smells, and such. At home I sometimes wear earprotectors. I noticed something funny. I'm quite literary walking on my toes so that I don't bother my downstairs neighbour. But with the earprotectors i'm less scared/anxious to disturb my neighbour. Even though i know that i'm not making less sound. How would you explain that? Does this implicate something? If so, what exactly? Thanks.

But why blindness? What about people who are born deaf? Why should the Visuel System be more important?

2:45 no pun intended
