Abstract
Brown-Séquard Syndrome (BSS) is a rare spinal cord injury characterized by asymmetrical motor and sensory dysfunction. Trauma to the spinal cord, particularly the hemi section, is the primary cause. Diagnosis involves a thorough medical history, physical examination, and imaging studies. Treatment focuses on stabilization, rehabilitation, and potential emerging therapies. This article provides a comprehensive overview of BSS, including its causes, symptoms, diagnosis, and treatment.

Introduction
Spinal cord injuries can result in a wide range of neurological deficits, and one rare yet fascinating condition is Brown-Séquard Syndrome (BSS). Brown-Séquard Syndrome (BSS) causes an uncommon neurological condition that causes a unique collection of sensory, motor, and autonomic dysfunctions. This syndrome, which Charles-Édouard Brown-Séquard first identified around 1850, frequently results from spinal cord damage or other traumatic causes[1]. This study of the literature intends an overview of the aetiology, clinical presentation, diagnostic techniques, treatment options, and prognosis of Brown-Séquard Syndrome.
Aetiology
The most frequent cause of Brown-Séquard Syndrome is trauma, which frequently results from piercing wounds like gunshots or stab wounds[2]. Additional reasons include spinal cord tumours, degenerative illnesses, viral disorders, hematomas[3] and iatrogenic injuries sustained during surgical treatments. The affected side experiences varying degrees of motor paralysis and loss of proprioception (awareness of body position) due to damage to the corticospinal tract and dorsal columns, respectively.
Symptomatic Presentation
The symptoms of BSS depend on the level of the spinal cord injury. For instance, if the injury occurs in the cervical region, both arms may be affected, while a thoracic-level injury affects the lower limbs.[4] The ipsilateral motor paralysis, ipsilateral loss of proprioception, and contralateral loss of pain and temperature sensation below the site of the lesion make up the typical clinical trial of Brown-Séquard Syndrome[5]. The spinal cord's physical configuration, in which proprioceptive and motor fibres ascend ipsilaterally and pain and temperature routes decussate and ascend contralaterally, results in this pattern[6] However, discrepancies in how BSS is presented have been noted, highlighting the need for individual patient assessment.
Diagnostic Strategies
Brown-Séquard syndrome must be identified through a comprehensive clinical assessment. Imaging methods like computed tomography (CT) scans and magnetic resonance imaging (MRI) is essential for locating the exact position and size of the lesion in the spinal cord[7]. Additional tests, such as electromyography (EMG) and somatosensory evoked potentials (SSEP)[8], may be conducted to assess the integrity of neural pathways and provide further diagnostic confirmation. These tests help differentiate BSS from other spinal cord injuries and neurological conditions.
Management Techniques
A comprehensive approach is used to treat Brown-Séquard syndrome with the goal of reducing functional limitations and raising the quality of life[9]. The main goals of acute interventions are to stabilise the patient, treat any injuries that are present, and guard against additional problems like respiratory compromise and deep vein thrombosis. Maximising functional recovery requires early rehabilitation, which includes physical and occupational therapy. Pharmacological interventions such as analgesics, muscle relaxants and spasticity management agents, may be utilized to alleviate symptoms and enhance mobility[10].
Rehabilitation plays a significant role in the recovery process for individuals with BSS. Physical therapy aims to restore strength, flexibility, and coordination in the affected limbs. Occupational therapy helps individuals regain independence in daily activities, while assistive devices and adaptive equipment can facilitate mobility and enhance the quality of life.
Pain management strategies may include medications, nerve blocks, or other interventional procedures tailored to the individual's needs. Psychological support is also essential to address the emotional and psychological impact of the syndrome.
Prognosis
Brown-Séquard Syndrome's prognosis is greatly influenced by the nature, severity, and extent of spinal cord damage. The result may also depend on the patient's age, general health, and the existence of comorbid conditions. While some people might recover significantly from their functional impairments, others would continue to have neurological deficiencies. Current studies into cutting-edge therapies, like stem cell therapy and neurodegenerative methods, show promise for enhancing long-term prognosis.
Conclusion
A distinctive pattern of spinal cord injury characterises the rare and complicated neurological illness known as Brown-Séquard Syndrome. For maximising patient outcomes, prompt diagnosis and a multidisciplinary therapy strategy are essential. Improvements in diagnostic procedures and therapy approaches offer hope for a better prognosis and functional recovery. Additional investigation is required to improve our comprehension of the underlying systems and create cutting-edge therapeutic approaches.
