Brown-Sequard syndrome

Brown-Séquard syndrome, also known as Brown-Séquard's hemiplegia and Brown-Séquard's paralysis, is a loss of motricity (paralysisand 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 symptomsinclude same-side loss of motor control, fine touchand sensation of vibration; and opposite-side loss of sensation of temperature(thermoanesthesia) and pain(analgesia) that begins 2 or 3 segments below the lesion.

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