Hello, It may not be easy to treat ADHD in kids and teenagers. If ADHD remains incompletely treated, it does a toll on child s self esteem also & too many times, in a desire to get noticed, get some appreciation, child engages into undesirable behaviors which are at present your main concern. There are medications which can be used and include methylphenidate or atomoxetine. As a part of parent teacher management, we can engage into token economy, contingency management, role plays, time out etc., which are taught by Psychologist to both the parents & teachers in school. Hence, do contact your Psychologist for PTMT; if need further help do revert to me. Hope I have answered your query. Let me know if I can assist you further.
