[Neuropsychic disorders in functional dysphonias].

A total of 110 patients with functional vocal disorders secondary to neurosis were examined. They included 50 patients with neurasthenia, 30 with hysteria, and 21 with obsessive neurosis. The pattern of vocal disorder had its own peculiarities in each form of neurosis. All patients were subjected to multiple modality treatment: drug therapy, psychotherapy, respiratory gymnastics, and phonopedics. The treatment resulted in the disappearance of neurotic symptoms, normalization of the respiratory rate, and the complete restoration of vocal function. Thus, a clinical follow up of patients with functional vocal impairments and analysis of cause-and-effect relationships prompt the conclusion that functional dysphonia is a neurotic symptom whereas laryngeal alterations are secondary to pathological voice production.
