Trauma to the spinal cord, such as neck hyperflexion injuries, are often the result of car accidents or sports-related injuries. In such injuries,<unk>  dislocations and extensions occur without the rupture of ligaments. This blunt trauma may be further complicated with subsequent disc compression. In addition to these complications, transient ischemic attacks could occur in the spinal cord during spinal artery occlusion. Common pathological sources of PCS include Friedreich's Ataxia, an autosomal-recessive inherited disease, and tumors such as astrocytoma, ependymoma, meningioma, neurofibroma, sarcoma, and schwannoma. Illustration of an axon with a degenerated myelin sheath Cobalamin, commonly known as vitamin B12, plays a crucial role in the synthesis and maintenance of myelin in neurons found in the spinal cord. A deficiency of this essential vitamin results in demyelination, a deterioration of the axon's layer of insulation causing interrupted signal transmission, with a currently unknown specificity to the<unk>  region. PCS may develop with the failure to treat syphilis. Symptoms typically appear during the tertiary phase of the disease, between twenty and thirty years after the initial syphilis infection. Failure to treat syphilis leads to progressive degeneration of the nerve roots and<unk>  columns. The bacteria Treponema pallidum that causes syphilis results in locomotor ataxia and tabes dorsalis. Further complications from tabes dorsalis include optic nerve damage, blindness, shooting pains, urinary incontinence, and degeneration of the joints. In most cases, lesions present bilaterally. However, in rare cases, lesions have been seen unilaterally. Moreover, general symptoms of<unk>  spinal artery infarcts include ipsilateral loss of proprioceptive sensation, fine touch, pressure, and vibration below the lesion; deep tendon areflexia; and in severe circumstances, complete paralysis below the portion of the spinal cord affected.
