Lesions of the brain above the pons interrupt the higher conscious control of voiding. The voiding reflexes of the lower urinary tract—the primitive voiding reflex—remain intact. Affected individuals show signs of urge incontinence and experience symptoms of overactive bladder. The bladder empties too quickly and too often, with relatively low volumes of urine, and deferring voiding or storing a large volume becomes difficult. Waking frequently at night to void is also common in such situations. 

Typical examples of a brain lesion are stroke, brain tumor, and head trauma. Hydrocephalus, cerebral palsy, and Shy-Drager syndrome are also central nervous system pathologies that impact voiding function. Dementia can impact the socially appropriate control of voiding, as well.
