This observational study is looking at people of all ages who have behavioral, psychiatric, or developmental disorders that started in childhood. Researchers want to understand how these conditions develop and how they are inherited within families. They are also interested in unique presentations of these disorders, especially those linked to genetics or family history. The goal is to learn more about these conditions to help doctors better understand and treat them in the future. This study is not testing any specific treatments or interventions. It aims to gather information from up to 1,000 participants, including those with a diagnosis and their biological relatives.
