BACKGROUND: Several pharmacologic and nonpharmacologic therapeutic options have been
used to treat cough that is not associated with a pulmonary or extrapulmonary etiology.
METHODS: We conducted a systematic review to summarize the evidence supporting diff erent
cough management options in adults and children with psychogenic, tic, and habit cough.
Medline, EMBASE, the Cochrane Central Register of Controlled Trials, Cochrane Database of
Systematic Reviews, and Scopus were searched from the earliest inception of each database to
September 2013. Content experts were contacted, and we searched bibliographies of included
studies ...

METHODS: We conducted a systematic review to summarize the evidence supporting diff erent cough management options in adults and children with psychogenic, tic, and habit cough. Medline, EMBASE, the Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus were searched from the earliest inception of each database to September 2013. Content experts were contacted, and we searched bibliographies of included studies to identify additional references. RESULTS: A total of 18 uncontrolled studies were identifi ed, enrolling 223 patients (46% male subjects, 96% children and adolescents). Psychogenic cough was the most common descriptive term used (90% of the studies). Most of the patients (95%) had no cough during sleep; barking or honking quality of cough was described in only eight studies. Hypnosis (three studies), suggestion therapy (four studies), and counseling and reassurance (seven studies) were the most commonly used interventions. Hypnosis was eff ective in resolving cough in 78% of the patients and improving it in another 5%. Suggestion therapy resolved cough successfully in 96% of the patients. Th e greatest majority of improvements noted with these forms of therapy occurred in the pediatric age group. Th e quality of evidence is low due to the lack of control groups, the retrospective nature of all the studies, heterogeneity of defi nitions and diagnostic criteria, and the high likelihood of reporting bias. CONCLUSIONS: Only low-quality evidence exists to support a particular strategy to defi ne and treat psychogenic, habit, and tic cough. Patient values, preferences, and availability of potential therapies should guide treatment choice.
