Adolescence typically describes the years between ages 13 and 19 and can be considered the transitional stage from childhood to adulthood. However, the physical and psychological changes that occur in adolescence can start earlier, during the preteen or "tween" years (ages 9 through 12). Adolescents can struggle with anxiety, depression, ADHD, bipolar, eating disorders, schizophrenia, self-harm, substance abuse, suicide, or other forms of distress that are developmentally appropriate but will not necessarily endure. At Concept Plus, we work closely with parents and children to identify worrying signs and take a balanced approach to dealing with increasingly independent young people.
