###Human: Kindly explain the symptoms of ADHD. ###Assistant: Hi.  To answer your question regarding ADHD: Most people with ADHD will have displayed signs and symptoms of the disorder from a young age, usually before 12 years old. In this case your ADHD will usually have been noticeable and picked up by teachers or parents at a younger age. However, many cases can be missed and only picked up later. In this case I recommend referral to a general practitioner who can more reliably assess the situation. A referral to a psychiatrist can always be made, if necessary. This is also bearing in mind that there can be multiple reasons why you might find difficulties concentrating. Therefore, it is better to proceed slowly and start with a GP consultation before jumping into any treatment of ADHD which can involve powerful medications that can have serious side effects. A screening test for ADHD like the Conner’s test filled in by both the child’s teacher and parents. To be seen for a thorough examination by a family practitioner. If there is evidence of potential ADHD, then referral to a psychiatrist or child and a dole scent psychiatrist would be the next step. As per the findings of the GP or psychiatrist. The young patients symptoms should not be completely ignored and a proper thorough investigation should be done in order that something potentially serious is not missed.
