Welcome to Health Care Magic.
We understand your concern.
I am Dr Alok Sinha, MD Psychiatry from india.
I will try to help you.
In children ADHD
is a well known psychiatric diagnosis characterised with poor attention & concentration and hyperactivity. The child does not sit at a place still & runs here and there. Child does not complete a work and before ending picks up another task again just to leave it incomplete too. Due to poor attention the child does not pay attention at teacher's/parent's words leading to poor learning at school and non adherence to elder's instructions at home. The child can not register things and events in memory due to lack of attention and concentration. While writing they dont use punctuation marks and do silly grammatical errors.
If most of the above things are true in your child's case then he may be sufferring from ADHD.
The children with ADHD can not wait for their turn, are often impulsive and may quarrel with others on minor issues. Sometimes the child feels an inner intense compulsion to do certain things that may violate others's right. Thus conduct disorder
is a co-morbidity often, as it happened in your child's case.
If a child like your son with such a problem is brought to me, I will do following things to have a holistic view of problem.
1. IQ testing to rule out co-morbid Mental Retardation.
brain to find out any structural pathology if there.
3. Screening for "Autistic spectrum disorder"
4. Detail history and EEG to rule out any seizure
Secondly your concern is right as the child with ADHD is not immune for other mental illness & he very well may have more than one psychiatric problems at a time.
We have to treat child as a whole not as a ADHD patient only. Parents & teachrrs have a very important role in therapy as they are well aware of the child's problem and also readily available for behavioural modification.
You must consult a good child psychiattist who may evaluate your child personally in detail. He may prescribre certain medicines for his illness and behaviour control. He may also tailor a behavioural therapy programme as needed and may involve you also in the therapy of your child.
With constant effort he can be cured. I wish you & your child all the best.
Hope this answered your question.
