Living With Damaged Nerves: What Are the Causes and Symptoms of Demyelination?

The body is filled with nerves; this is how we experience the world as well as feel pain. Nerves serve an important function in telling our brains when something is wrong so that we can take the appropriate measures to rectify the situation.

But sometimes, the nerves can stop working properly due to demyelination. What is this process and what can be done to prevent it from happening?

What is Demyelination?

The nerves in the body are surrounded by a protective layer of a substance called myelin. It’s similar to the insulation surrounding electric wires, allowing the electrical messages of the body to flow in the right direction towards the brain.

Demyelination occurs when these myelin sheaths are damaged, resulting in scar tissue forming. The electrical signals can’t move as efficiently through this scar tissue, so the nerves aren’t working as well as they should.

What Are the Symptoms of Demyelination?

The most common symptoms of disorders that cause demyelination include:

  • Muscle spasms
  • Muscle weakness
  • Muscle stiffness
  • Vision loss
  • Sensory changes
  • Alteration in bladder and bowel movements

What are the Causes of Demyelination Disorders?

Demyelination can be caused by a number of conditions that affect the myelin sheaths of nerves. These include:

  • Viruses
  • Genetics
  • Inflammation from the body’s immune response attacking the myelin sheaths
  • Lack of oxygen to the brain
  • Damage to blood vessels in the brain

Because of this, there is no cure for these conditions. The only proper response is getting treatment as early as possible to minimize the severity of the symptoms. Treatment usually involves medications to help with painful and stiff muscles, while physical therapy can get the muscles moving again in the way they’re supposed to.

What Are The Types of Demyelination Disorders?

There are several disorders and diseases that can cause damage to myelin sheaths. These include:

  • Multiple Sclerosis (MS): this is the most common demyelination disorder and is an autoimmune condition that attacks the optic nerve, the spinal cord, and the brain.
  • Acute Disseminated Encephalomyelitis (ADEM): children are more likely to contract ADEM, and although the infection period is brief, it can still cause damage to the myelin in the brain and spinal cord. Other symptoms of ADEM include low energy, confusion, nausea, and vomiting.
  • Balo’s Disease (Concentric Sclerosis): the symptoms are similar to MS, leading doctors to believe that it is a rarer form of the disorder. Symptoms appear quickly and become worse in a short amount of time; it is known to be fatal. Along with the symptoms of MS, Balo’s Disease will also present high fever, memory loss, paralysis, seizures and trouble talking or understanding information.

Other demyelination disorders include Transverse Myelitis, Neuromyelitis Optica, Charcot-Marie-tooth Disease, HTLV-I Associated Myelopathy, Schilder’s Disease, and Guillain-Barre Syndrome.

Unfortunately, there are no known cures for demyelination disorders or how to prevent demyelination from occurring. The best treatment is the management of symptoms in order to minimize pain and keep the muscles strong and flexible through physical therapy.
