Hello.
You should consider Asperger's syndrome in your son. he has a family history. You can observe his behaviors and find out if he fits in the criteria for Asperger's syndrome or any other Pervasive Developmental Disorder (PDD) like autism.
About 10 - 15 % children with autism have seizures. And the brain size is smaller then normal children of their age.
Have you taken him to a pediatrician or a pediatric neurologist ?
Regards
Hi,
I am sorry to hear that your step-son is suffering from seizures. Decrease in white matter suggests that his abilities to co-ordinate things, gross motor activity and fine motor activity might be affected.
Yes there are incidences where in there is an association between ADHD, Aspergers and your step-sons decreased white matter.
Keep me informed if you have any queries.
Bye.
