Functional speech disorders: clinical manifestations.
Patients with psychogenic voice disorder (PVD), a disorder of voice in the absence of identifiable pathology, present a particular challenge to clinicians. Although the voice can usually be restored by the use of speech therapy, recurrences can only be prevented by psychotherapeutic intervention.

Richard A.L. Macdonell, Rhonda Holmes, in Neurology and Clinical Neuroscience, 2007. Nonorganic Disorders of Voice. Voice disorders may have a psychological basis, rather than being the result of pathology affecting neural pathways or muscular control. The most common psychogenic speech disorders affect voice, fluency, or prosody.
Stuttering, also called stammering or dysphemia, speech defect characterized by involuntary repetition of sounds or syllables and the intermittent blocking or prolongation of sounds, syllables, and words. These disruptions alter the rhythm and fluency of speech and sometimes impede communication, with consequences on the affected individual’s confidence when speaking.
Conversion disorder (CD), or functional neurologic symptom disorder, is a diagnostic category used in some psychiatric classification systems.
The need to consider the psychosocial and psychopathological aspects of neurologic communicative disorders, and the link between emotional and communicative processes, are emphasized. Diagnostic criteria for the identification of psychogenic communicative disorders are outlined.
Dissociative amnesia (formerly psychogenic amnesia): the temporary loss of recall memory, specifically episodic memory, due to a traumatic or stressful event. It is considered the most common dissociative disorder amongst those documented.
