Abstract

Acquired psychogenic or functional speech disorders are a subtype of functional neurologic disorders. They can mimic organic speech disorders and, although any aspect of speech production can be affected, they manifest most often as dysphonia, stuttering, or prosodic abnormalities. This chapter reviews the prevalence of functional speech disorders, the spectrum of their primary clinical characteristics, and the clues that help distinguish them from organic neurologic diseases affecting the sensorimotor networks involved in speech production. Diagnosis of a speech disorder as functional can be supported by sometimes rapidly achieved positive outcomes of symptomatic speech therapy. The general principles of such therapy are reviewed.
