Question

Type of sensation lost on same side of Brown Sequard syndrome

• A. Pain
• B. Touch
• C. Proprioception
• D. Temperature

Answer 1

The Correct Option is C

In Brown-Séquard syndrome, there is a hemisection of the spinal cord. This leads to different types of sensory loss on opposite sides of the body:

• Same side (ipsilateral) to the lesion: Loss of proprioception and fine touch due to damage to the dorsal columns.
• Opposite side (contralateral) of the lesion: Loss of pain and temperature sensation due to disruption of the spinothalamic tract, which crosses to the opposite side a few segments above where the sensation enters the spinal cord.

Therefore, the sensation lost on the same side as the lesion in Brown-Séquard syndrome is proprioception.
