The Symptoms of ADHD

The most common condition that mimics ADHD in our region in the northeast is vitamin D deficiency. About a third of the children that I see at my clinic have an undiagnosed and untreated vitamin D deficiency, which will cause problems with attention and mood. We also have kids that have visual tracking problems and visual convergence problems. These all should be evaluated and treated by the child's doctor before we start treatment for ADHD.
