Giggle incontinence: Evolution of concept and treatment

Background: Giggle incontinence is a sudden and involuntary episode of urinary incontinence that is provoked by an episode of laughter. Decades of case studies and small research studies have formed the basis of what is known about giggle incontinence; however, much remains unknown about this type of incontinence, leaving the recommendations for clinical management somewhat unguided.

Methods: A systematic review of 22 articles on the topic of "giggle incontinence" and related terms was conducted, including all published articles and commentaries since the term was first seen in print in 1959.

Results: This review provides a historical context for the diagnosis, a summary of what is known about its etiology, and a summary of current treatments.

Conclusions: There is disagreement about the pathophysiology of laughter incontinence, with two differing explanations. The first emphasizes the neurologic origin of the cascade of events during laughter and urination, and draws a likeness to cataplexy and other CNS disorders, and emphasizes treatment with methylphenidate. The second emphasizes urologic dysfunction, with biofeedback and bladder retraining as the recommended therapy. Comprehensive treatment of children with laughter incontinence requires an appreciation of both concepts. Since inception of the concept there has been question about the appropriateness of the term "giggle incontinence." This review encourages discussion among readers/clinicians about the term and the essential qualities of the diagnosis.
