Brown-Sequard syndrome (BSS) is a rare
neurological disorder characterized by a lesion on the
spinal cord which results in weakness or
paralysis (hemiparaplegia) on one side of the body and a loss of sensation (hemianesthesia) on the opposite side. BSS may be caused by a spinal cord
tumor,
trauma (such as a puncture wound to the neck or back), degenerative disease,
ischemia[?] (obstruction of a blood vessel), or infectious or
inflammatory diseases[?] such as
meningitis,
shingles,
tuberculosis, or
multiple sclerosis.
Generally treatment for individuals with BSS focuses on the underlying cause of the disorder. Early treatment with high-dose steroids may be beneficial in many cases. Other treatment is symptomatic and supportive.
