Most paralyses caused by nervous-system damage (e.g., spinal cord injuries) are constant in nature; however, some forms of periodic paralysis, including sleep paralysis, are caused by other factors.Paralysis can occur in newborns due to a congenital defect known as spina bifida. Spina bifida causes one or more of the vertebrae to fail to form vertebral arches within the infant, which allows the spinal cord to protrude from the rest of the spine. In extreme cases, this can cause spinal cord function inferior to the missing vertebral arches to cease. This cessation of spinal cord function can result in paralysis of lower extremities. Documented cases of paralysis of the anal sphincter in newborns have been observed when spina bifida has gone untreated. While life-threatening, many cases of spina bifida can be corrected surgically if operated on within 72 hours of birth. 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 Landrys ascending paralysis)
Tick paralysisAscending paralysis contrasts with descending paralysis, which occurs in conditions such as botulism. Other animals
Many animal species use paralyzing toxins to capture prey, evade predation, or both. In stimulated muscles, the decrease in frequency of the miniature potentials runs parallel to the decrease in postsynaptic potential, and to the decrease in muscle contraction. In invertebrates, this clearly indicates that, e.g., Microbracon (wasp genus) venom causes paralysis of the neuromuscular system by acting at a presynaptic site. Philanthus venom inhibits both the fast and slow neuromuscular system at identical concentrations.
Doctors told his mother Lisa van Dyke that he was the first case of harlequin ichthyosis in South Africa, and that she has a one-in-four chance to have another child with the disease. Hunter Steinitz (born October 17, 1994) is one of only twelve Americans living with the disease and is profiled on the National Geographic "Extraordinary Humans: Skin" special. Mui Thomas (born in 1992 in Hong Kong) qualified as first rugby referee with harlequin ichthyosis. A female baby born in Nagpur, India in June 2016 died after two days. She is reported as the first case in India. References
