Brown Sequard syndrome | Podcast | Dr. MEK

Welcome to Dr. MEK's Podcast Series! This episode covers essential high-yield medical topics, perfect for all medical and healthcare providers, especially for anesthesia and medical professionals. 🚀

Topics Covered in This Episode: Brown-Séquard Syndrome

1. Introduction

Brown-Séquard Syndrome (BSS) is a neurological condition resulting from damage to one side of the spinal cord, leading to a characteristic pattern of motor and sensory deficits. Also known as transverse hemisection syndrome or hemiplegia syndrome, it is classified as an incomplete cord syndrome.

2. Aetiology and Causes

Definition: BSS occurs due to damage or injury to one half of the spinal cord.
Causes:

Spinal cord tumors

Traumatic injuries (e.g., falls, gunshot wounds)

Ischemia (reduced blood flow)

Infectious or inflammatory diseases (e.g., tuberculosis, multiple sclerosis)

3. Pathophysiology

BSS results from damage to key spinal cord pathways:

Corticospinal Tract: Controls voluntary movement. Damage below the level of pyramidal decussation results in ipsilateral spastic weakness (upper motor neuron lesion).

Lower Motor Neurons (at injury level): Damage causes ipsilateral lower motor neuron signs (e.g., flaccid paralysis, muscle atrophy).

Dorsal Columns: Carry proprioception, fine touch, and vibration. Damage leads to ipsilateral loss of these sensations below the lesion.

Spinothalamic Tract: Transmits pain and temperature. Damage results in contralateral loss of pain, temperature, and crude touch sensations below the lesion.

4. Symptoms

Ipsilateral (same side as lesion):

Spastic weakness (corticospinal tract involvement)

Loss of proprioception, fine touch, and vibratory sensations (dorsal column involvement)

LMN signs at the level of lesion

Loss of pain, temperature, and crude touch at the level of the lesion (before fibers cross)

Contralateral (opposite side of lesion):

Loss of pain, temperature, and crude touch below the lesion (spinothalamic tract damage)

5. Diagnosis

Neurological history & trauma history (if applicable)

Physical examination findings

Additional investigations:

Lab tests for infections (e.g., tuberculosis, multiple sclerosis)

Imaging (MRI/X-ray) to identify structural causes (trauma, tumors, etc.)

6. Treatment

Antibiotics: Standard prophylactic antibiotics may be used to prevent infections.

Steroids: Controversial in traumatic spinal cord injuries due to infection risk and lack of proven effectiveness in BSS.

Treatment depends on the underlying cause (e.g., surgical intervention for tumors, medical management for infections/inflammation).

7. Conclusion

Brown-Séquard Syndrome is a distinct neurological disorder with a characteristic sensory-motor deficit pattern. Understanding its pathophysiology, diagnosis, and treatment is essential for effective management and improved patient outcomes.
