Nervous System Disorders That Lead to Bladder Spasms The feeling

involuntary response. The brain signals the bladder muscle when
it is time to tighten (contract) and release urine. However,
certain nervous system disorders cause damage to the nerves that
send signals between the brain and the bladder. When this
happens, the bladder does not work properly. "Neurogenic
bladder" is the general term for bladder problems due to nerve
damage. Nervous system disorders and injury that can cause
bladder spasms include: - Brain tumor - Cerebral palsy - Herpes
