Multiple Sclerosis l: Introduction01:19

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Degenerative Disc Disease ll: Pathophysiology

The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Summary

Cervical spondylotic myelopathy (CSM) is a common condition caused by aging. Surgical decompression may improve function for those with moderate to severe deficits, while mild cases can be monitored.

Area of Science:

  • Neurology
  • Spinal Surgery

Background:

  • Cervical spondylosis is a common aging process involving degenerative changes in the cervical spine.
  • These changes can compress the spinal cord, leading to cervical spondylotic myelopathy (CSM), the most frequent cause of myelopathy in adults.
  • Congenital narrowing of the cervical canal increases risk.

Purpose of the Study:

  • To summarize the anatomy, pathophysiology, clinical presentation, diagnosis, natural history, and treatment of CSM.
  • To inform neurologists about this prevalent condition.

Main Methods:

  • Review of existing literature on cervical spondylotic myelopathy.
  • Discussion of diagnostic tools including magnetic resonance imaging (MRI) and electrophysiologic testing.
  • Evaluation of treatment options, including conservative management and surgical decompression.

Main Results:

  • CSM presents with signs of cervical spinal cord dysfunction, potentially with nerve root injury and neck/limb pain.
  • MRI is the primary diagnostic tool; electrophysiology aids in excluding other conditions.
  • Conservative treatment efficacy is unproven; surgery offers potential benefits but carries risks.

Conclusions:

  • Neurologists must be familiar with CSM.
  • Mild CSM cases may be managed with monitoring.
  • Surgical decompression (anterior or posterior) is recommended for progressive, moderate-to-severe neurologic deficits.
