Patient discussion about defect

Q. Is it a birth defect in children? I know about the causes of autism. Is it a birth defect in children?

A. it's not an easy answer i'm afraid...there are congenital differences, but no "birth defect" that we can detect. there's a good pdf file that gives a full explanation about it...i think you'll find it useful:

Q. why does ADHD make kind of an hype to children? is it a nerve defect?

A. it's a complex interaction among genetic and environmental factors causing a disorder in the central nervous system. a study showed a delay in development of certain brain structures n the frontal cortex and temporal lobe, which are believed to be responsible for the ability to control and focus thinking.
