Although he was never diagnosed as having ADHD by a professional, my husband and I believed that our son had it.  He caused many problems for himself as well as others and wound up in jail for attacking his brother with a knife.

While in jail, he was diagnosed as having schizophrenia, which my father had as well.

About 2 years later, after he had been out of prison for about a year, he committed suicide about 2 weeks after my father had died.  He was 23 years old.

I now have a 12 yr. old son who I believe  has ADD and an 8 yr. old who I'm sure has ADHD.  Therefore,  I need to know what to be on the lookout for.

Could my son's ADHD have developed into schizophrenia or was I wrong?  Is it possible that my son had schizophrenia all along (since childhood) and it didn't manifest itself until he got older?

My 8 year old has spoken about seeing things (e.g. a face in the bathroom  and red eyes).

I'm not sure what to make of this.

Please advise me and if possible include some case histories similar to mine.
