Colorectal dysfunction due to spinal cord injury can be classified in to two types: an upper motor neuron lesion or lower motor neuron lesion. Problems with the upper motor neuron in a neurogenic bowel results in a hypertonic and spastic bowel because the defecation reflex centre, which causes the involuntary contraction of muscles of the ...
Congenital conditions and tumors that compress the cord can also cause SCI, as can vertebral spondylosis and ischemia. [5] Multiple sclerosis is a disease that can damage the spinal cord, as can infectious or inflammatory conditions such as tuberculosis, herpes zoster or herpes simplex, meningitis, myelitis, and syphilis. [12]
The disease can also be caused by inhalation of nitrous oxide, which inactivates vitamin B12. [11] Vitamin E deficiency, which is associated with malabsorption disorders such as cystic fibrosis and Bassen-Kornzweig syndrome, [12] can cause a similar presentation due to the degeneration of the dorsal columns.

Two of the genetic disorders that may affect spinal tumors, include Von Hippel-Lindau disease and Neurofibromatosis 2. Von Hippel-Lindau disease is a non-cancerous tumor of blood vessels that occur in the brain, spinal cord, or even tumors in the kidneys. The Neurofibromatosis 2 is a non-cancerous tumor that usually affects the nerves for hearing.
Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness , or weakness in the arms or legs. [ 1 ]
The specific causes of neurological problems vary but can include genetic disorders, congenital abnormalities or disorders, infections, lifestyle, or environmental health problems such as pollution, malnutrition, brain damage, spinal cord injury, nerve injury, or gluten sensitivity (with or without intestinal damage or digestive symptoms).
Conversely, a lower motor neuron lesion affects nerve fibers traveling from the anterior horn of the spinal cord or the cranial motor nuclei to the relevant muscle(s). [ 1 ] Upper motor neuron lesions occur in the brain or the spinal cord as the result of stroke , multiple sclerosis , traumatic brain injury , cerebral palsy , atypical ...
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 can lead to additional loss of movement or feeling, or the onset of pain or autonomic nervous system symptoms. [6]
