Psychogenic cough: ACCP recommends that psychogenic cough in children should be diagnosed only if tic disorders are excluded and the cough improves with behavioral interventions or psychotherapy; cough characteristics are only suggestive of psychogenic cough, not diagnostic. The clinical features and diagnostic clues of psychogenic cough are: (1) it is more common in older children; (2) it is predominantly a daytime cough that disappears when focused on an event or at nighttime rest; (3) it is often associated with anxiety symptoms; (4) it is not associated with organic disease and other causes of chronic cough are excluded.
