I am starting to wonder if my son may be misdiagnosed as ADHD. I know he has a lot of the symptoms, but the behaviour issues are escalating instead of getting better. I was talking to my mother the other day and she asked me if I thought he could have COS - Childhood Onset Schitzophrenia. I started thinking back over the past year or so and things started clicking into place...So I called bio-dad to get his family history! What an eye opener! difficult child Bio#1 has heard voices in his TV but says they are not scary voices...they just talk alot. He has seen people in our driveway and garage that are not really there....at the time I chalked it up to being psychic, cause I see things sometimes too. Many of the other symptoms of COS are similar to ADHD. So....my mother tells me my psychiatric thought I could have COS when I was 15. I was never diagnosed, because I moved out on my own and never went back to see the Dr. Is it any wonder I see things sometimes.... Then I talk to bio-dad, who says that bio-grandpa was hospitalized for 5 years for schitzophrenia and Bi-polar...and that Bio-dad takes seroquel for bi-polar (but is also used to treat schitzophrenia. Does anyone here have any experience with COS? Any suggestions on what I can do until I can get him evaluated and figure out what the heck is going on?
