Psychogenic cough tic: a case report.

: A case of psychogenic cough tic is presented to demonstrate the problems and complications that can arise from misdiagnosis of this dramatic and disabling disorder. It can be confused with TS and may be treated more aggressively than is beneficial. A single case with a recurrent course is described with the hypothesis of a possible autoimmune contribution. The combination of organic precipitants and emotional maintaining factors suggests that psychogenic cough tic is a condition that lies between somatization and transient tic disorder.
