What Causes Mental Disorders in Children?
The exact cause of most mental disorders is not known, but research suggests that a combination of factors, including heredity, biology, psychological trauma, and environmental stress, might be involved.
Heredity (genetics): Many mental disorders run in families, suggesting that the disorders, or more accurately, a vulnerability to the disorders, might be passed on from parents to children through genes.
Biology: As in adults, many mental disorders in children have been linked to abnormal functioning of particular brain regions that control emotion, thinking, perception, and behavior. Head traumas also can sometimes lead to changes in mood and personality.
Psychological trauma: Some mental disorders might be triggered by psychological trauma, such as severe emotional, physical, or sexual abuse; an important early loss, such as the loss of a parent; and neglect.
Environmental stress: Stressful or traumatic events can trigger a disorder in a person with a vulnerability to a mental disorder.
How Is Mental Illness in Children Diagnosed?
As with adults, mental disorders in children are diagnosed based on signs and symptoms; however, diagnosing mental illness in children can be especially difficult. Many behaviors that are seen as symptoms of mental disorders, such as shyness, anxiety (nervousness), strange eating habits, and outbursts of temper, can occur as a normal part of a child's development. Behaviors become symptoms when they occur very often, last a long time, occur at an unusual age, or cause significant disruption to the child's and/or family's life.
