6.2. Causes of autonomic dysreflexia

There can be many stimuli that cause AD. Anything that would have been painful, uncomfortable, or physically irritating before the injury may cause AD after the injury. The most common cause seems to be overfilling of the bladder. This could be due to a blockage in the urinary drainage device, bladder infection (cystitis), inadequate bladder emptying, bladder spasms, or possibly stones in the bladder.

Stimuli That Cause Autonomic Dysreflexia:

Bladder (most common)


Skin-related disorders

Sexual Activity
