“Impairments that we see in autism seem to be partly due to different parts of the brain talking too much to each other,” neuroscientist, Ralph-Axel says.
Scientists at Columbia University Medical Center are looking closely at how the brain development of autistic children may help explain some symptoms like oversensitivity to noise and social behavior. There is strong evidence to suggest a pruning problem rather than an over-production problem in the brains of children with autism. The failure to trim synapses in the brains of autistic children is providing clues as to how autism develops from childhood on. Although it is too early to know the impact of specific medicines that may help clear out unnecessary synapses and lead to important behavioral changes in autistic children, recent research lends hope for future benefits.
