Pediatric Functional Neurologic Symptoms

Functional neurologic disorders (FND) of children have many similarities to those of adults, and there is a potential to learn much from the study of FND in children. In this chapter we discuss multiple aspects of pediatric FND. These include their frequency, historic features, the diagnosis, and controversies over the nature of FND and the "correct" name that should be used. We also discuss methods of informing the child and family of the diagnosis, treatment, and prognosis. FND of children typically affect girls in the 10-14-years age range. The presentation is often polysymptomatic, with pain and lethargy accompanying loss of motor function. A common situation is a perfectionistic child who has taken on too much in her academic, sporting, cultural, and social life. Some children respond readily to treatment, but others have a prolonged illness.
