Variations
Paralysis can occur in localised or generalised forms, or it may follow a certain pattern. Most paralyses caused by nervous-system damage (i.e. spinal-cord injuries) are constant in nature; however, some forms of periodic paralysis, including sleep paralysis, are caused by other factors.
Ascending paralysis presents in the lower limbs before the upper limbs. It can be associated with:
- Guillain–Barré syndrome (another name for this condition is Landry's ascending paralysis)
- Tick paralysis
Ascending paralysis contrasts with descending paralysis, which occurs in conditions such as botulism.

Famous quotes containing the word variations:
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
