Dear Safia:
Sorry to hear about the problems your son is having. Certainly the neuronal migration problems seen in your son MIGHT be related to the VZV infection during the pregnancy. But, there are several things that go against that thought. Prenatal infection with VZV is usually more of wide spread disorder with expecially the lung and adrenal gland involved. The immunoglobulin seen in your newborn was likely the result of your passing your IgG antibody across the placenta. The lesion in the CNS would be more of cystic lesions within the brain matter itself, rather than simple migrational problems. The arachnoid cysts seen in your son are not usual type of process seen in VZV. So, although anything is possible, I would favor that the neuronal migration problems seen in your son are not the result of in utero infection.
Hang in there with your son. Early intervention is absolutely necessary, PT, OT, Speech, and interaction to produce as much as possible to reach his potential. Nothing is written in stone about his future, so keep hopeful.
Sincerely,
CCF Neuro MD
