Question

What is the characteristic pattern seen in Brown sequard syndrome -

• A. C/L loss of joint sense and position
• B. C/L loss of pain
• C. I/L loss of complete sensory functions
• D. C/L motor functions

Answer 1

The Correct Option is B

Brown-Séquard syndrome is a neurological condition resulting from the hemisection, or partial injury, of the spinal cord. This injury results in a distinctive pattern of neurological deficits.

The characteristic pattern of Brown-Séquard syndrome is:

• Ipsilateral Loss of Motor Function: Damage to the corticospinal tract leads to weakness or paralysis on the same side (ipsilateral) as the injury.
• Ipsilateral Loss of Proprioception and Vibration Sense: Damage to the dorsal columns results in loss of proprioception, vibration sense, and fine touch on the same side as the injury.
• Contralateral Loss of Pain and Temperature Sensation: Damage to the spinothalamic tract results in loss of pain and temperature sensation on the opposite side (contralateral) to the injury.

From the provided options, the correct characteristic related to Brown-Séquard syndrome is:

C/L (Contralateral) loss of pain

This occurs due to the disruption of the spinothalamic tract, which crosses to the opposite side of the spinal cord a few segments above where it enters, leading to contralateral loss of pain and temperature sensations.
