Age four is generally considered too young for such a diagnosis.
The sooner you get a diagnosis or rule this diagnosis out the better. I don't know how early they start screening but you can talk to your pedi. My child was diagnosed with ADHD @ 6; but since the age of 3 I had been thinking: wow why doesn't he listen, why is he so defiant. He couldn't help it! duh.... the sooner the better.
hi, I just had my 4 year old tested for adhd, we made an appointment with an excellent child psychologist. He gave me a list of behaviour questions to answer and one for her kindy to fill out too. They have carried out a number of tests for IQ and behaviour. He told me that adhd is neurological and runs normally down the male side of the family, its more uncommon in girls but not completely impossible as I have found. I suggest to any parent thinking that their child has add, adhd or odd( oppositional defiance disorder) thatyou speak to your gp and then gain consultation from a qualified child psychologist for help, But i do not agree with medicating a child so I have concerntrated solely on her behaviour patterns, sleep patterns, diet, anyfood intolerances and any changes on day to day routine and their immediate environmental surroundings. I feel for you my daughter was really acting out but she has become so much better since working on a range of factors may i also suggest you purchasing the book and dvd on1,2,3, magic child behaviour system I now use it with my daughter and things have never been better, good luck
Anyway, you might try getting the book, "The ADD/ ADHD Answer book," by Susan Ashley. Its pretty easy to go through. And it gives you tons of advice for school, home, and later life.
In terms of an early diagnosis. Most doctors won't till she is 6, because they need the input from teachers (or people in another setting besides the home). If you can get an early assessment from your school district - go for it. The sooner she can get help. The better it is for her. And yes, It is very important to get diagnosed as early as possible because it changes how you and the schools work with her. This has nothing to do with you being with her 24/7, but everything to do with helping her.
I can also give you lots of online sites, if you want more information. But, the book is really good. Best wishes.
