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]
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.
This is the only type also known as an "Arnold–Chiari" malformation. As opposed to the less-pronounced tonsillar herniation seen with Chiari I, there is a larger cerebellar vermian displacement. Low-lying torcular herophili (confluence of sinuses), tectal beaking , and hydrocephalus with consequent clival hypoplasia are classic anatomic ...
The impairment of cerebral blood flow that underlies hypertensive encephalopathy is still controversial. Normally, cerebral blood flow is maintained by an autoregulation mechanism that dilates arterioles in response to blood pressure decreases and constricts arterioles in response to blood pressure increases. This autoregulation falters when ...
Dizziness can be brought on by issues inside and outside of the brain. Here are all the possible triggers and what you can do about them, according to a doctor.
The couple and their daughter were all born with myelomeningocele, which is the most serious type of spina bifida and can cause moderate to severe disabilities, such as not being able to move your ...
This delayed presentation of symptoms relates to the degree of strain on the spinal cord over time. [5] Tethering may also develop after spinal cord injury. Scar tissue can block the flow of fluids around the spinal cord. Fluid pressure may cause cysts to form in the spinal cord, a condition called syringomyelia.
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
