What is MS (multiple sclerosis)? 

Multiple sclerosis (MS) is a disease that causes demyelination, or disruption of the substance that coats and protects nerve cells, in the spinal nerve and brain cells. The specific symptoms and severity of the disease are related to the exact areas of the nervous system that are affected and the extent of the damage to the myelin. Therefore, MS can cause many different kinds of signs and symptoms in areas throughout the body.

Multiple sclerosis occurs predominantly in younger persons, with those aged 15 to 60 most commonly diagnosed with the condition. The average age of diagnosis is about 30 years; however, multiple sclerosis has been identified at all ages but is rare in children.

Is MS hereditary (genetic, runs in families)?

People who have a first-degree relative with MS tend to have a slightly higher risk for developing the disease, but overall, genetic or hereditary factors are not believed to play a significant role in determining who develops MS.

Is MS painful?

While many of the symptoms of MS are not associated with pain (see below), painful involuntary muscle contractions can occur in some people with MS. The burning and tingling sensations of MS can also be painful. In total, over half of all people with MS report experiencing some kind of short-term or long-term pain.

Can You Get MS Through Saliva or Blood?

MS is not contagious, you cannot get it through saliva or blood because it can not be passed from person to person. the cause if MS is not known; however scientists theorize that multiple sclerosis is triggered by a combination of factors.

  1. Immunological factors
  2. Genetics (hereditary, runs in families)
  3. Infections, for example:
    • Viruses such as the Epstein-Barr virus or mononucleosis
    • Bacteria
  4. Environmental factors, for example:
  • Where you live or grew up (geographical location).
  • Vitamin D deficiency
  • Smoking
  • Obesity

    Are the early signs and symptoms for MS different in men and women? 

    Any of the early signs and symptoms of MS can occur in both men and women and are not specific. However, certain symptoms such as pregnancy problems or erectile dysfunction (ED, impotence), are gender-specific symptoms.

    What are the early signs and symptoms of MS progression (stage)?

    Signs and symptoms of MS progression can include worsening of any of the signs and symptoms mentioned above as well as the development of additional symptoms listed above that were not present at the initial diagnosis.

    What are the 4 types of MS?

    There are four different types of MS:

    1. Relapsing-remitting multiple sclerosis (RRMS) is the most common form of MS. People with this type of MS develop symptoms that respond to treatment and then resolve. Episodes of remission may last for weeks to years.
    2. Secondary-progressive multiple sclerosis (SPMS) occurs when the symptoms of an exacerbation don’t fully resolve during a remission.
    3. Primary-progressive multiple sclerosis (PPMS) progresses over time, without episodes of remission.
    4. Progressive-relapsing multiple sclerosis (PRMS) occurs when there are escalating symptoms over time along with intermittent episodes of remission.
