Types Of Multiple Sclerosis

Time heals all wounds except relapsing-remitting MS.

And primary-progressive MS.

And secondary-progressive MS.

And whole bunch of other age-related illnesses, like glaucoma, age-related macular degeneration and malignancy.

At least time is good for adhesive capsulitis, alternatively known as frozen shoulder!

Multiple sclerosis

MS is a chronic disease involving immune-mediated attacks on the central nervous system. Demyelination causes mayhem.

As a parallel, Guillan-Barre acutely affects the peripheral nervous system. When it’s chronic, it’s called chronic inflammatory demyelinating polymyopathy.

Symptoms

Neurological symptoms ensue after the disease has passed a threshold.

  • Optic neuritis, characterised by painful visual loss in an eye
  • Numbness, weakness
  • Ataxia, spasticity
  • Fatigue
  • Pain
  • Sexual and urinary dysfunction, such as detrusor overactivity causing urgency

Clinically isolated syndrome is a one-off presentation of demyelination that can progress to MS.

Investigations

MRI can show brain lesions.

CSF analysis can show inflammation.

Evoke potential measurement can show demyelination.

Treatment

Ongoing: immunotherapy agents.

Acute relapse: high-dose corticosteroids.

Spasticity: baclofen

Spasms: benzodiazepines

Mobility: fampridine

Paroxysmal symptoms: carbamazepine

Urinary symptoms: oxybutynin

Pregnancy

The risk of MS relapse is lower during pregnancy and higher in the first 3 months after giving birth.

Summary of major demyelinating illnesses

Central nervous system: clinically isolated syndrome (acute), MS (chronic)

Peripheral nervous system: Guillan-Barre (acute), CIDP (chronic)
