Spina bifida (SB; / ˈ s p aɪ n ə ˈ b ɪ f ɪ d ə /; [9] Latin for 'split spine') [10] is a birth defect in which there is incomplete closing of the spine and the membranes around the spinal cord during early development in pregnancy. [1] There are three main types: spina bifida occulta, meningocele and myelomeningocele. [1]
It is also important to understand the role of birth defects in the development of hindbrain malformations that can lead to syringomyelia, as syringomyelia is a feature of intrauterine life and is also associated with spina bifida. Learning when these defects occur during the development of the fetus can help with the understanding of this and ...

[9] [10] Estimates of the prevalence of dyscalculia range between 3 and 6% of the population. [9] [10] In 2015 it was established that 11% of children with dyscalculia also have attention deficit hyperactivity disorder (ADHD). [11] Dyscalculia has also been associated with Turner syndrome [12] and people who have spina bifida. [13]
In children, a tethered cord can force the spinal cord to stretch as they grow. In adults the spinal cord stretches in the course of normal activity, usually leading to progressive spinal cord damage if untreated. [1] TCS is often associated with the closure of a spina bifida. It can be congenital, such as in tight filum terminale, or the ...
Spina bifida is a neural tube defect that involves defects in the development of the spine, and it can cause hydrocephalus. Myelomeningocele is the most severe type of spina bifida, involving an open spinal column and the exact mechanism of hydrocephalus involved in this condition is unclear.
Spina bifida occulta means hidden split spine. [20] In this type of neural tube defect, the meninges do not herniate through the opening in the spinal canal. [19] The most frequently seen form of spina bifida occulta is when parts of the bones of the spine, called the spinous process, and the neural arch appear abnormal on a radiogram, without ...
Spina bifida is the most common defect impacting the Central Nervous System (CNS). The most common and most severe form of Spina Bifida is Myelomeningocele. Individuals with Myelomeningocele are born with an incompletely fused spine, and therefore exposing the spinal cord through an opening in the back.
