The experience has been observed across all ages, yet the presentation and underlying etiology vary across the developmental scale. In the developing nervous system, these changes occur rapidly as a child’s awareness and ability to express this symptom as a problem mature and the very nature of the symptoms evolves. Although many of the well observed patterns of adult head pain are applicable to children, the unique aspects of evaluating and treating children in association with the variations that occur in childhood headache disorders continue to make the management of these diseases a challenge. A perspective that goes beyond the downward application of information derived from the adult headache experience is needed. This book will help you answer challenges specific to pediatric headache. This universal nature of head pain creates a familiarity that is both a barrier and a challenge.
