Multiple sclerosis (MS) occurs in the human body when the immune system attacks the coverings protecting nerves (or myelin). This loss of protection disrupts communication between the brain and the rest of the body. The true cause is unknown, although genetics plays a role as does lack of exposure to sunlight. Younger white women living in temperate climates have a higher incidence.

The following are early signals of MS:

1. Vision problems
This is one of the earliest multiple sclerosis symptoms. It is not the typical eyesight problem such as needing new glasses or reading glasses. It involves problems that come on suddenly. An example is double vision that lasts a significant amount of time. Blurry vision is also a symptom as is temporary loss of sight in one eye. Any of these signs means a person should seek medical treatment as soon as possible.

2. Tingling or numbness
Another of the MS early warning signs, this is similar to vision problems. It is not the tingling from sleeping on your hand and cutting off the blood flow. It involves prolonged loss of feeling that does not abate with movement. Look for this sensation on one side of the body. An arm or a leg can both exhibit these signs.

3. Pains and spasms
The term for this sign is spasticity. It affects the ability to walk which is one of the disabling features of MS. The simple explanation is stress on the joints of the knees, hips, and ankles. Pain is a natural result of MS and spasticity.

4. Weakness or fatigue
One of the major complaints of people suffering from MS is fatigue. They just do not have the energy to move. That stems in part from the weakness in the muscles. When combined with the pain and spasms discussed above, the act of walking becomes a chore. It is an effort to accomplish much of anything.

5. Balance issues
Vertigo is another word for dizziness. The lack of balance is what some people call lightheaded. While this sign may happen occasionally, if it suddenly shows up it is another tip that a diagnosis of MS may be the appropriate one.

6. Bladder problems
The bladder functions properly when communication occurs between the brain and the spinal cord. MS disrupts this process just as it does with other symptoms and signs. If a person cannot hold the correct quantity of urine or does not fully empty the bladder, then MS may be the cause.

7. Cognitive issues
This symptom affects memory and the ability to stay focused. The mind just does not work the way it used to function. A person may notice an inability to process incoming data from various sources. This is not the slowing of an aging brain. As noted earlier, MS generally occurs in younger persons who should not have cognitive problems.

There is no cure for MS. The disease tends to flare up, and then go into remission, and when it comes back, it is usually stronger with greater disability.
