There is a 10-15% chance. I'm of the strong belief if any parent has a chronic illness their child should be in therapy. The therapist will tell you if your son is unwell. There are a lot of doctors that diagnosis kids with just adjustment disorder or mood disorder nos solely for insurance. Pigeonholing a kid to mental illness is not what most doctors want. They want to treat the child with the best privacy just in case through therapy and/or medication they don't fit the diagnosis as they get older. My son was diagnosed at 8 but has not been given the formal diagnosis because his doctor wanted to wait until he had to be hospitalized to formally dx him. She did give us heads up and help with skills. So then we move his new diognosis is impulse control issues.
