A term initially used in West Africa to refer to a condition experienced by high school or university students in response to the challenges of schooling. Symptoms include difficulties in concentrating, remembering, and thinking. Students often state that their brains are "fatigued." Additional somatic symptoms are usually centered around the head and neck and include pain, pressure or tightness, blurring or vision, heat, or burning. "Brain tiredness" or fatigue from "too much thinking" is an idiom of distress in many cultures, and resulting syndromes can resemble certain Anxiety, Depressive, and Somatoform Disorders.
