Dear user Welcome to HCM We understand your concerns I went through your details. Lack of attention, impulsivity, and/or hyperactivity are the bench mark symptoms of ADHD. But even any one of these symptoms are present abnormally it is diagnosed as Attention Deficit Hyperactivity Disorder. Common causes could be lack of discipline, negative family problems, too much TV or smart phone or social site use or gaming or internet addiction. Treatment depends on the symptoms and needs an expert intervention. I suggest you to consult a psychiatrist for diagnosis ad treatment. In the meantime, you can engage in physical exercise, relaxation techniques etc as an interim measures. If you require more of my help in this aspect, please use this URL. http://yyyygl/yyyyyyy.
