Enuresis, or involuntary urination, primarily affects children over the age of five and can be classified as nighttime incontinence. Incidence rates for enuresis range from 1.4% to 28% among children aged 6 to 12, with risk factors such as family history, stress, and certain medical conditions. Management strategies include behavioral changes, enuresis alarms, and medications, while complications may involve low self-esteem and social limitations.
