Just as the diagnosis of ADHD cannot be confirmed by brain MRI or blood tests, the effectiveness of ADHD treatment cannot be determined by these tests. The effectiveness of medication is still determined by observing the child’s performance in school and regular follow-up visits to assess attention and behavior. Yang Liangzheng of the Children’s Health Care Center at Jinan Children’s Hospital, parents and teachers should see the effects of methylphenidate treatment between 30 and 90 minutes after the drug is administered, and the effects fade around 8-12 hours after the drug is administered. This means that it may be difficult for parents to observe the effects of treatment during school hours, and then teachers need to be asked regularly if their child’s performance at school has improved. With treatment with tomoxetine, some children may show significant improvement within a week of taking the medication, although many children will still take 2-6 weeks to gradually achieve the most pronounced effect, even with the right dose of treatment. Although it takes some time to find the most appropriate dose of medication to titrate a child, it is certain that medication for ADHD is effective! The fact is that at least 90% of children treated with one medication alone, or a combination of two medications, get fairly good results. When treatment with ADHD medication is started, many symptoms may then be relieved, but of course, it is common for so many stubborn symptoms to linger, which is why children with ADHD should be treated with a combination of psycho-behavioral therapy in addition to medication to help completely relieve ADHD symptoms. Psycho-behavioral therapy, which generally takes months for the treatment to take effect, is also generally more durable and stronger.
