I just finished my Psychiatry rotation as part of my training and there are three things, of many, that I learned: First, America has a
long way to go in developing the best screening and management tools for people with mental disabilities. Second, schizophrenia is an
incredibly complicated illness that can take manifest in a whole host of unsuspecting symptoms, and is not easily treatable. And third, diagnosing and treating a mental disorder in children is
really hard.
The last two points, I think, are very relevant to this article. While I sympathize with you, understand that child development is a very, very complicated thing. You have naturally hyper children, naturally withdrawn children, etc, and physicians are very wary to label any child with an illness, especially schizophrenia. When we're adults and have leveled out, it's easier to discern what is "normal" from "abnormal." But children are constantly changing, being molded by their environment, and so it's much harder to outline a symptomatic threshold of what's considered normal. Additionally, children exhibit mental disorders in very different ways than adult do; there are different sets of symptoms to look out for. And these symptoms can be anything from "pressured speech" (talking too fast. some kids are just naturally fast talkers, right?) to auditory hallucinations (but the child could have a vivid imagination, right?).
The treatment for schizophrenia is an entirely different beast. The goal is usually to just suppress the symptoms and to restore the patient to a functional baseline. In many cases, the disease progresses and the prognosis worsens. In your case, your child had early-onset schizophrenia, which is associated with a worse prognosis than late-onset cases.
Although there are studies that show that early detection and treatment of schizophrenia can improve the course of the disease, chances are your kid would have still developed much of the same symptoms and issues that he has now. It really sucks, and I sympathize with you, but that's the nature of the disorder. It's terrible, difficult to manage effectively, and can ruin lives. I've seen it.
