Re: 13 y.o. Anxiety/ADHD...Help
If the attention problems are CAUSED BY anxiety, then the stimulants probably won't help. Sometimes, though, ADHD and school struggles can cause anxiety. You and your son's psychiatrist need to sort out which came first.
With ADHD children, though, specific behavioral interventions help a lot. For example, "Child has trouble remembering to write down homework assignments." So you work on that one task, help him develop a workable system. An ADHD coach can help a lot.
