Children and adolescents with headaches commonly complain of dizziness that creates significant distress among the patients and their families. Dizziness is largely due to either orthostatic intolerance or vertigo; this distinction is the initial step in the evaluation of a child with co-occurrence of headaches and dizziness. Vertiginous symptoms are most commonly due to vestibular migraine or benign positional vertigo. This review would focus its attention on the diagnosis, evaluation, and management of orthostatic intolerance, specifically postural orthostatic tachycardia syndrome.
