If your child has adhd, do you give medication or not?

Depends. This all depends on the child's specific situation. Some children do well on adhd meds, some do not. It is best to work with your pediatrician to try a combination of adhd drug trials and work with a mental health counselor or child psychiatrist to find a solution that works for you and your child.
Yes, for best result. If your child has been properly diagnosed with adhd, that means that he or she has a relative deficiency in certain neurotransmittors and the medicine helps restore the balance of these neurotransmittors so the brain can function optimally. You would not think of denying a person with low thyroid level of their thyroid medication, or a person with insulin-dependent diabetes of their insulin.
