(deep sigh): For many years I have had parents asking me if their children need Ritalin. Personally, I have never seen a patient with a Ritalin deficiency. That said, I do encourage parents and patients to perform urine and saliva tests for neurotransmitter and endocrine screening, and treat the problem, rather than the symptoms. I also prescribe and refer for rehabilitative therapy for acquired functional disorders and neuro-developmental delays. We need to educate pediatricians, pediatric nurses and teachers to look for signs of problems and actually diagnose the cause. And don’t get me started on the increasing numbers of kids in elementary school with anxiety disorders!
