Which neurological events commonly precipitate new-onset urge incontinence?

• A. Migraine.
• B. Hypertension.
• C. Diabetes.
• D. Stroke or spinal cord injury; other neurodegenerative conditions can also contribute.

Answer: (D)

New-onset urge incontinence is most often caused by disruption of the neural control of the bladder. The brain and spinal cord normally suppress involuntary detrusor contractions until a person is ready to void. When a neurological event injures these pathways—such as stroke or spinal cord injury—the bladder can become overactive, leading to sudden urgency and leakage. Neurodegenerative conditions (like MS, Parkinson’s, or advanced dementia) can similarly erode inhibitory control, producing the same symptom pattern. Migraines or hypertension aren’t direct insults to the bladder control system, and diabetes tends to cause bladder dysfunction via autonomic neuropathy that more commonly results in reduced sensation or impaired emptying rather than a new overactive bladder from a central injury.
