What Is Multiple Sclerosis? Multiple sclerosis or MS is a disease that affects the brain and spinal cord, resulting in loss of muscle control, vision, balance, and sensation (such as numbness). With MS, the nerves of the brain and spinal cord are damaged by one’s own immune system. Thus, the condition is called an autoimmune disease Autoimmune diseases are those whereby the body’s immune system, which normally targets and destroys substances foreign to the body such as bacteria, mistakenly attacks normal tissues. In MS, the immune system attacks the brain and spinal cord, the two components of the central nervous system. The central nervous system is made up of nerves that act as the body’s messenger system. Each nerve is covered by a fatty substance called myelin, which insulates the nerves and helps in the transmission of nerve impulses, or messages, between the brain and other parts of the body. These messages control muscle movements, such as walking and talking.   MS gets its name from the buildup of scar tissue (sclerosis) in the brain and/or spinal cord. The scar tissue or plaques form when the protective and insulating myelin covering the nerves is destroyed, a process called demyelination. Without the myelin, electrical signals transmitted throughout the brain and spinal cord are disrupted or halted. The brain then becomes unable to send and to receive messages. It is this breakdown of communication that causes the symptoms of MS. Although the nerves can regain myelin, this process is not fast enough to outpace the deterioration that occurs in MS. The types of symptoms, severity of symptoms, and the course of MS vary widely, partly due to the location of the scar tissue and the extent of demyelination. MS is two to three times as common in females as in males and its occurrence is unusual before adolescence. A person has an increased risk of developing the disease from the teen years to age 50, with the risk gradually declining thereafter. Early Symptoms of MS

  • Blurred or double vision
  • Thinking problems
  • Clumsiness or a lack of coordination
  • Loss of balance
  • Numbness
  • Tingling
  • Weakness in an arm or leg

No two people have exactly the same symptoms of MS.

You may have a single symptom, and then go months or years without any others. A problem can also happen just one time, go away, and never return. For some people, the symptoms become worse within weeks or months.

Interesting facts:

One in 20 Australians will be touched by MS through a family member, colleague or friend with the disease.

An estimated 23,000 people in Australia have MS. Approximately 1,000 Australians are diagnosed with MS every year.

Most people will be diagnosed in their twenties and forties.

MS affects three times as many women as men and the gap is widening.
