Common disorders among children

Mental health disorders in children — or developmental disorders that are addressed by mental health professionals — may include the following:

• Anxiety disorders. Anxiety disorders in children are persistent fears, worries or anxiety that disrupt their ability to participate in play, school or typical age-appropriate social situations. Diagnoses include social anxiety, generalized anxiety and obsessive-compulsive disorders.
• Attention-deficit/hyperactivity disorder (ADHD). Compared with most children of the same age, children with ADHD have difficulty with attention, impulsive behaviors, hyperactivity or some combination of these problems.
• Autism spectrum disorder (ASD). Autism spectrum disorder is a neurological condition that appears in early childhood — usually before age 3. Although the severity of ASD varies, a child with this disorder has difficulty communicating and interacting with others.
• Eating disorders. Eating disorders are defined as a preoccupation with an ideal body type, disordered thinking about weight and weight loss, and unsafe eating and dieting habits. Eating disorders — such as anorexia nervosa, bulimia nervosa and binge-eating disorder — can result in emotional and social dysfunction and life-threatening physical complications.
• Depression and other mood disorders. Depression is persistent feelings of sadness and loss of interest that disrupt a child's ability to function in school and interact with others. Bipolar disorder results in extreme mood swings between depression and extreme emotional or behavioral highs that may be unguarded, risky or unsafe.
• Post-traumatic stress disorder (PTSD). PTSD is prolonged emotional distress, anxiety, distressing memories, nightmares and disruptive behaviors in response to violence, abuse, injury or other traumatic events.
• Schizophrenia. Schizophrenia is a disorder in perceptions and thoughts that cause a person to lose touch with reality (psychosis). Most often appearing in the late teens through the 20s, schizophrenia results in hallucinations, delusions, and disordered thinking and behaviors.
