Methods to manage ADHD symptoms include medication, cognitive or behavioral therapy, and organizational strategies.
There is conflicting evidence on the benefits of diet and nutrient supplementation for ADHD, but a nutritious diet may improve overall health and help reduce ADHD symptoms in some cases.
