Editing Paralysis (section)

==Causes==
Paralysis is most often caused by damage in the [[nervous system]], especially the [[spinal cord]]. Other major causes are [[stroke]], [[Physical trauma|trauma]] with [[nerve injury]], [[poliomyelitis]], [[cerebral palsy]], [[peripheral neuropathy]], [[Parkinson's disease]], [[ALS]], [[botulism]], [[spina bifida]], [[multiple sclerosis]], and [[Guillain–Barré syndrome]]. Temporary paralysis occurs during [[REM sleep]], and dysregulation of this system can lead to episodes of [[sleep paralysis|waking paralysis]]. Drugs that interfere with [[action potential|nerve function]], such as [[curare]], can also cause paralysis.
