Today, "Autism" means many different things to different people. The core
impairments
in autism involve social empathy, motor "mirroring", and communication,
but individuals
with autism also often have brain-based difficulties in visual and / or
auditory processing,
attention, and integrative activities that require the coordination of
large brain networks.
It's becoming increasingly clear that the diagnostic criteria need to be
clarified, though,
with more attention to considering "autism look-alikes" or confounding
primary sensory
or perceptual disorders.
Several studies
have now found significant
abnormalities in auditory and language
perception in the brain (see above).
Also visual processing problems
can complicate social interactions (right).
Some individuals may have a hard time seeing
a whole 'picture' of a face at one time, while problems with the
emotional reading of faces
hampers others.
Children or adults with autism may have large shifts in
sensory or motor maps, which would make it
difficult to plan motor movements, respond easily
to change, or reliably sense the environment.
Below you can see that autistic subjects had
trouble activating frontal brain pathways
compared to non-autistic controls, when
looking at familiar faces.
