Major depression disorder is a form of depression that affects 5 percent of children in the United States, according to the National Institute of Mental Health (NIMH). To be diagnosed with major depression disorder, the child must have five or more symptoms that continue for over two weeks, and the symptoms must also interfere in the child's life. The symptoms of major depression disorder affect the child both behaviorally and emotionally; major depression disorder can also impact the child's performance in school.
Behavioral Symptoms
The National Mental Health Information Center states that major depression disorder can significantly affect the child's behavior; however, the center notes that the child will identify that he is depressed first, followed by identification by his parents. Many of the symptoms of major depression disorder in children resemble those of an adolescent acting out, such as outbursts of shouting or reckless behavior. The child may threaten or attempt to run away from home. Changes may occur in the child's eating or sleeping habits; for example, the child may eat less and spend more time sleeping. Other behavioral symptoms include a loss of interest in activities, missing school and poor performance in academics.
Emotional Symptoms
The most prominent emotional symptom of major depression disorder in children is persistent sadness, according to the National Mental Health Information Center. The child may also have unexplained irritability or outbursts of crying. Other emotional symptoms include hopelessness and boredom. In cases of severe major depression disorder, the child has thoughts about death and committing suicide. This is a serious symptom that should not be ignored---medical attention is highly recommended.
Additional Symptoms
Some children may turn to alcohol or drugs as a result of major depression disorder, according to the National Mental Health Information Center. Aches and pains are another symptom, which are not alleviated by treatment.
