Brains of Children with Autism Fail to Trim Synapses – NY Times article and a Question

A fascinating article in the NYTimes about a new study of children with autism.

A few interesting points:

Babies grow many synapses connecting the neurons in their brain. As they grow up, they prune these synapses.

It looks like autistic children may not prune these synapses as well as other children and teenagers do. Their problems with social learning may be due to having too many connections in the brain.

They may also have a problem clearing out old and degraded cells.

From the NYT article:

“‘Impairments that we see in autism seem to be partly due to different parts of the brain talking too much to each other,” he said. “You need to lose connections in order to develop a fine-tuned system of brain networks, because if all parts of the brain talk to all parts of the brain, all you get is noise.'”

This overconnectivity in the brain could explain “symptoms like oversensitivity to noise or social experiences, as well as why many people with autism also have epileptic seizures.”

More than a third of people with autism have epilepsy!!!!

Is there any connection between this and gender dysphoria?

Probably not, but it is interesting to speculate. What if gender dysphoria is also caused by overconnectivity in the brain, just less of it? Perhaps gender dysphoria is caused by too many connections in just one part of the brain. That might explain why there are more people than you would expect with both ASDs and gender dysphoria. Something for someone to research, perhaps.

It might also be interesting to find out if people with gender dysphoria have a higher rate of epilepsy than expected.
