Disease Description (Causes and Symptoms)
Myelopathy is a condition that causes abnormalities in motor, sensory, and autonomic nerve function due to damage or dysfunction of the spinal cord. There are various causes, including degenerative compression (spinal canal stenosis, herniated disc, spondylolisthesis, etc.), inflammatory causes (acute or chronic myelitis, multiple sclerosis, etc.), infectious causes (vertebral osteomyelitis and myelitis), vascular causes (spinal cord infarction), tumors (intramedullary or extramedullary tumors), autoimmune diseases (lupus, Behçet disease, etc.), metabolic or nutritional causes (e.g., subacute combined degeneration), and neurodegenerative diseases (e.g., amyotrophic lateral sclerosis).
Main Symptoms
- Numbness, decreased sensation, or abnormal sensations in the limbs (tingling, electric shock-like sensations)
- Muscle weakness and gait disturbance (staggering or slowed steps)
- Paralysis of the lower limbs or all four limbs
- Bladder and bowel dysfunction (urinary incontinence, difficulty urinating)
- Pain (localized pain or radiating pain)
- Balance problems and increased risk of falls
- In severe cases, altered consciousness or difficulty breathing (such as with brainstem or upper thoracic spinal cord lesions)
Key pathophysiology: Spinal cord compression, inflammation, or ischemia damages nerve fibers and axons, blocking signal transmission. With continuing damage, reversible functional impairment may progress to irreversible atrophy and necrosis.
Treatment Methods and Precautions
The goals of treatment are to eliminate the cause when possible, preserve and restore neurological function, and prevent complications. Treatment varies depending on the cause.
Main Treatment Options
- If compression (such as degenerative compression or a tumor) is identified on imaging: surgical decompression (decompression surgery, fusion surgery, etc.) — early surgery is recommended when there is neurological deterioration or progressive symptoms.
- Inflammatory or immune-mediated myelitis: high-dose intravenous steroids (e.g., intravenous methylprednisolone for 3–5 days); if steroid-refractory, plasmapheresis or IVIG; immunosuppressants as needed (for recurrent or chronic management).
- Infectious causes: treatment based on the causative pathogen, such as appropriate antibiotics, antivirals, or antituberculosis drugs.
- Vascular causes (spinal cord infarction): management of blood flow and blood pressure during the acute phase, and rehabilitation.
- Nonsurgical treatment for degenerative causes (when symptoms are mild and nonprogressive): physical therapy, pain management, orthoses, and medication (such as analgesics and muscle relaxants) — however, surgery should be considered in cases of progressive neurological deficits.
- Degenerative and neurodegenerative diseases (e.g., ALS): there is no specific curative treatment. Medication (such as riluzole and edaravone), respiratory, nutritional, and rehabilitation care, and symptom-relieving treatment.
- Rehabilitation: physical therapy, occupational therapy, bladder and bowel management education, and assistive devices such as orthoses and walkers.
Precautions (Including Patient Self-Care)
- Visit a medical institution immediately if symptoms worsen (such as sudden muscle weakness, loss of sensation, or acute bladder dysfunction)
- Prevent falls and trauma (use assistive devices and remove hazards indoors)
- When using steroids, monitor for side effects such as infection risk, high blood sugar, osteoporosis, and gastrointestinal bleeding
- When nerve damage persists long term, prevent pressure ulcers and deep vein thrombosis (DVT) (through repositioning, compression stockings, etc.)
- If bladder dysfunction is present, prevent urinary retention and urinary tract infections (catheter management and urinalysis)
- When taking medication, check the prescription, side effects, and drug interactions
Checklist Before an Outpatient Visit (What to Bring and Example Questions)
What to Bring and Information to Prepare
- A list of all medications currently being taken (including prescription drugs, nonprescription drugs, and supplements)
- Medical history (especially autoimmune diseases, infectious diseases, history of cancer, and surgical history)
- Recent test materials (previous MRI/CT/X-ray reports or imaging CDs, blood test results, urinalysis, urine culture, etc.)
- The time of symptom onset and progression (when they began, gradual or acute onset, variation during the day)
- Symptom pattern: which areas are uncomfortable and how (sensory, motor, bladder, or bowel problems, etc.), and aggravating or relieving factors
- Photos or videos related to falls or gait disturbance (if possible)
- Allergy information (medications, contrast agents, etc.)
Information That Is Helpful to Tell the Doctor in Advance During an Outpatient Visit
- Whether there has been acute worsening (rapid deterioration over the past few days)
- Fever or systemic symptoms (possible infection)
- Whether immunosuppressive treatment is currently being received (may affect infection risk and test interpretation)
Example Questions (Patient → Doctor)
- What do you think is causing these symptoms? (Compressive vs. inflammatory vs. vascular, etc.)
- What additional tests are needed (MRI, CSF examination, evoked potentials, etc.)?
- Do I need surgery right away, or can my condition be monitored with conservative treatment?
- What is the purpose of the medication you plan to prescribe, and what side effects should I expect?
- What activities should I avoid in daily life (exercise, driving, etc.)?
Examples of General Questions to Ask the Doctor
- What is the exact cause of this disease, and what cause do you think applies in my case?
- What treatment options (surgery, medication, and rehabilitation) are recommended, and what are the expected benefits and risks of each?
- What is the likelihood of recovery (prognosis) after treatment? How long is recovery expected to take?
- What are the main side effects of the medication to be used, and what precautions are needed with long-term use?
- What lifestyle changes or additional tests (regular follow-up examinations) are recommended to prevent recurrence?
Examples of Disease-Specific Questions
- Based on my MRI findings (or recent imaging), do I need decompression surgery now? What degree of neurological recovery can be expected before and after surgery?
- I have bladder dysfunction. How should I begin urodynamic testing or catheter management?
References and Medical Care Guidance
- The information above is general information, and the diagnosis and treatment plan may vary depending on an individual's test results and clinical findings. In the event of acute worsening (such as sudden paralysis, urinary retention, or difficulty breathing), immediate evaluation in an emergency room is necessary.
