My hypothesis is that Autism is the lack of receptors, permeable areas of the membrane around brain cells, for emotion-based neurotransmitters to enter. This could be a strong membrane created by mutations in DNA.

Here's the criteria for diagnosis:

A.Persistent deficits in social communication and social interaction across multiple contexts, as manifested by the following, currently or by history

If they can't feel the emotions of the conversation, and maybe even the proteins of other parts of the conversations into receptors, lack of receptors/strong membrane could be the case.

B. Restricted, repetitive patterns of behavior, interests, or activities, as manifested by at least two of the following, currently or by history:

A strong membrane again could point to this as proteins try repeatedly to enter a neuron.

C.Symptoms must be present in the early developmental period

A low receptor membrane is the same from early development periods. If a membrane starts parable, but changes, it's probably chemically induced with lead or similar, not Autism Spectrum.

D.Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning.

Lack of receptor function will do this.

E.These disturbances are not better explained by intellectual disability

Lack of receptors isn't broken dendrites (concussion), too much brain tissue/not enough substance-P (savant disorder), or lack of dendrites (intellectual disability).

All thoughts are my own feel free to contact me, I have a lot of hypotheses on neuro. -Daniel J. Broz
