On the falsehood of extinguishing the Asperger's diagnosis in DSM 5

[Guest guest]

Over the years, various studies have reported significant differences in

physiological characteristics between individuals with autism and

individuals with Asperger's.

Here is a study I chanced upon today. It's open access.

Regional cerebral blood flow in children with autism spectrum disorders:

a quantitative ^(9)^(9)mTc-ECD brain SPECT study with statistical

parametric mapping evaluation.

The decrease in rCBF in ASD is a global event, which involves the

bilateral frontal, temporal, limbic system and basal ganglias. Asymmetry

of hemispheric hypoperfusion was more obvious in the AS group than the

autism group, which indicates a different neurobiological mechanism from

that of autism.
