Brown-Séquard syndrome, also known as Brown-Séquard's hemiplegia and Brown-Séquard's paralysis, is a loss of motricity (paralysis and ataxia) and sensation caused by the lateral hemisection of the spinal cord. Other synonyms are crossed hemiplegia, hemiparaplegic syndrome, hemiplegia et hemiparaplegia spinalis and spinal hemiparaplegia.

Its symptoms include same-side loss of motor control, fine touch and sensation of vibration; and opposite-side loss of sensation of temperature (thermoanesthesia ) and pain (analgesia).

It was first described in 1850 by the British neurologist Charles Édouard Brown-Sequard (1817-1896), who studied the anatomy and physiology of the spinal cord.
