Final answer:
Mixed incontinence involves a combination of different types of urinary incontinence, including overactive bladder, stress urinary incontinence, and incontinence resulting from neurological disorders.
Step-by-step explanation:
Mixed incontinence refers to a combination of different types of urinary incontinence. One type is overactive bladder without any other contributing factors, where the detrusor muscle in the bladder contracts uncontrollably, leading to urgency and incontinence. Another type is stress urinary incontinence, which occurs due to pelvic floor weakness and causes leakage with activities that increase abdominal pressure. Mixed incontinence can also involve a combination of stress and urge incontinence. Lastly, incontinence resulting from neurological disorders can lead to urinary incontinence.
