Paralysis is the complete failure of muscle function for one or more muscle groups. Paralysis can cause loss of emotion or loss of mobility in the affected area.
Paralysis is most often caused by injure to the nervous system or brain, especially the spinal cord. Partial paralysis can also happen in the REM stage of sleep. Most important causes are stroke, trauma, poliomyelitis, amyotrophic lateral sclerosis (ALS), botulism, spina bifida, multiple sclerosis, and Guillain-Barré syndrome. Poisons that get in the way with nerve function, such as curare, can also cause paralysis. Many causes of this are varied, and could also be unidentified.
Paralysis may be localized, or generalized, or it may follow a certain instance. For instance, localized paralysis occurs in Bell's palsy where one side of the face may be paralyzed due to inflammation of the facial nerve on that side. Patients with stroke may be weak all over their body (global paralysis) or have hemiplegia (weakness on one side of the body) or other patterns of paralysis depending on the area of injure in the brain. Other patterns of paralysis occur due to different lesions and their sequelae.
