Why hyperactive children need excitatory medication Although children are hyperactive, it is due to a decrease in chemicals in certain areas of the brain, reduced excitability of the “command” and reduced management and control functions, including reduced control over movement, attention, logical reasoning, completion of plans and other behaviors, resulting in abnormal performance in these areas. abnormalities in these areas. The purpose of taking excitatory drugs is to increase the excitability of the “command” of the brain, to ensure effective control of behavior by the “command”, and to fundamentally reduce hyperactivity and focus attention. Addiction to euphoric drugs is extremely unlikely to occur at clinically therapeutic doses. On the contrary, several studies have reported that adolescents with ADHD treated with centrally stimulant medications are at significantly lower risk of developing addiction to other substances than those who are not treated, and that the earlier medication is used to treat ADHD, the lower the chances of substance abuse in adulthood. Will the medication affect the child’s height and weight? Central stimulants may have a decreased appetite at the beginning of treatment and may affect height and weight, but the effects on growth are non-persistent, mostly transient, and can easily be overcome by adjusting the dose. Experienced physicians will also have children undergo regular physical examinations to check height and weight so that treatment can be adjusted in a timely manner. One study showed that the effect of long-acting methylphenidate on height and weight was only 0.23 cm and 1.23 kg at 21 months, and that the social recovery and future development of the child were more important than the effect on height of less than 1 cm.
