[The tired child].

THE TIRED CHILD. Child fatigue is difficult to define and evaluate. This is a common reason for parental concern and consultation. The expressions of fatigue are variable according to age. An organic origin must be sought. It is rarely found when the symptom is isolated. Most often the origin of child and adolescent fatigue is environmental, related to living conditions. The analysis should focus on family constraints, sleep conditions, use of screens, school and activities. A psychological origin must be sought especially a depressive syndrome.
