Developmental disorders, such as Autism Spectrum Disorder, Attention Deficit Hyperactivity Disorder and Learning Disorders, are often called "unnoticed disorders." Shinshu University Hospital psychiatrist Hideo Honda is one of Japan's leading specialists in developmental disorders. He has clinical experience treating patients over time from early childhood to maturity, which is rare even on a global level. Honda asks, "What is 'normal?'" "How does one find happiness in life?" With these fundamental questions in his heart, he works closely with patients who have lost their confidence, and affirms their way of life.
