Anxiety disorder serves as an umbrella term for many disorder subtypes such as eating disorder, obsessive compulsive disorder, phobias, and social anxiety disorder. It is the most common mental illness in both children and adults and is very treatable, but according to CDC is the least treated.
Depression disorders most often seen in children are bipolar disorder and Disruptive Mood Dysregulation disorders. Bipolar disorder is a neurological disorder that causes extreme and unusual mood swings, energy, and activity levels effecting daily functioning and typically manifesting during pre-teen to teenage years. Disruptive Mood Dysregulation disorder has replaced Bipolar diagnosis in young children since they typically do not exhibit manic behavior, but rather irritability and anger.
Disruptive Behavior Disorders are the easiest to detect because they involve drastic behaviors that are not appropriate for the child’s age and are persistent and severe. All children misbehave, but these behaviors are out of the norm and disrupt the child’s daily functioning as well as the lives of the entire family. Disruptive behavior disorders include Oppositional Defiance Disorder (diagnosed in children) and Conduct Disorder (diagnosed in adolescents).
