Multiple Sclerosis (MS) Causes, Symptoms & Types
Ms is a progressive central nervous system disorder that affects the function of your brain and spinal cord.
It occurs when the immune system treats myelin sheath as a threat, therefore attacking the cells that produces it and the Myelin sheath itself.
This can alter communication between the brain and the rest of the body.
The scars left on the nerves inside the sheath after the attack is called sclerosis.
What causes MS is not known, but scientist suggest the factors below contributes in developing MS.
- Genetics: MS is not hereditary but researchers believes abnormalities in some genes increases your chances of developing it.
- Environmental – Researchers has linked lack of vitamin D in the body increases your chances in developing MS.
Multiple Sclerosis Symptoms
MS symptoms varies from one person to another, depending on the nerve fibre affected. Common symptoms includes;
- Vision problems – Pain in the eye, blurry vision, double vision.
- Tingling and muscle stiffening or tightness
- Bowel and bladder problems
- Sexual dysfunction – Lower sex drive
- Difficulty walking
There are four main type of MS, these are;
- Secondary progressive multiple sclerosis (SPMS)- This is one of the most common type of MS, characterised by worsening symptoms of Relapsing remitting multiple sclerosis. This means if you are diagnosed with SPMS, You may have had RRMS, and the neurologic function has just got worse.
- Progressive relapsing multiple sclerosis (PRMS)- Is the least common type of MS. Individuals that were diagnosed with PRMS are now considered to have PPMS as the symptoms are similar. PRMS symptoms are usually worse from the beginning.
- Primary progressive multiple sclerosis (PPMS)- This is the degeneration of neurological function. This type of MS is characterised into two points. Active and non active.
- Relapsing remitting multiple sclerosis (RRMS)- The majority of those diagnosed with RRMS are relatively young and symptoms may eventually develop into SPMS. RRMS is defined as a condition in which patients have new symptoms or worsening of conditions but get better or recover from it.
