Brown-Séquard Syndrome is a rare neurological disorder discovered by Charles Édouard Brown-Séquard in 1850, as he was studying injured farmers. These farmers were injured while cutting sugar cane in the Republic of Mauritius. This neurological disorder is also known as BSS, Hemiparaplegic Syndrome, Hemisection of the Spinal Cord, Partial Spinal Sensory Syndrome, or Spastic Spinal Monoplegia Syndrome.
Brown-Séquard Syndrome is a condition characterized by partial damage in the spinal cord, particularly an injury to only one side or just the half of the spinal cord. This partial damage to the spine results in hemiparaplegia, wherein weakness and degeneration (atrophy) of muscles or paralysis occur on the side of the affected area and hemianesthesia or the loss of sensation on the opposite side. This is usually caused by an injury to the spine, specifically in the region of the neck or back. This may also be caused by a spinal cord tumor, trauma, ischemia (obstruction of blood vessel), or infectious or inflammatory diseases such as multiple sclerosis and tuberculosis.
