What is multiple sclerosis?

Multiple sclerosis (MS) may be a disease during which the nerves of the central nervous system (brain and spinal cord) degenerate. Myelin, that provides a covering or insulation for nerves, improves the conduction of impulses along the nerves and is also vital for maintaining the health of the nerves. In multiple sclerosis, inflammation causes the myelin to disappear. Consequently, the electrical impulses that travel along the nerves decelerate, that is, become slower. additionally, the nerves themselves are broken. As a lot of and a lot of nerves are affected, someone experiences a progressive interference with functions that are controlled by the nervous system like vision, speech, walking, writing, and memory.

About 350,000 individuals within the U.S. have multiple sclerosis. Usually, someone is diagnosed with multiple sclerosis between twenty and fifty years older, however multiple sclerosis has been diagnosed in kids and within the elderly. Multiple sclerosis is twice as doubtless to occur in Caucasians as in the other cluster. ladies are twice as doubtless as men to be littered with multiple sclerosis earlier in life.

What causes multiple sclerosis?

The reason for multiple sclerosis remains unknown. within the last twenty years, researchers have centered on disorders of the immune system and genetics for explanations. The immune system is that the body's defender and is very organized and controlled. If triggered by an aggressor or foreign object, the immune system mounts a defensive action that identifies and attacks the invader and then withdraws. This method depends upon speedy communication among the immune cells and also the production of cells which will destroy the intruder. In multiple sclerosis, researchers suspect that a far off agent like a virulent disease alters the immune system in order that the immune system perceives myelin as an intruder and attacks it. The attack by the immune system on the tissues that it's presupposed to defend is named autoimmunity, and multiple sclerosis is believed to be a disease of autoimmunity. whereas a number of the myelin is also repaired once the assault, a number of the nerves are stripped of their myelin covering (become demyelinated). Scarring conjointly happens, and material is deposited into the scars and forms plaques.

Symptoms of multiple sclerosis

The central nervous system (brain and spinal cord) controls all of your body's actions. When MS damages the nerve fibres that carry messages to and from your brain, symptoms will occur in any a part of your body.

There are many various symptoms of MS and that they have an effect on every person differently. a number of the foremost common symptoms include:
  • numbness and tingling
  • blurring of vision
  • issues with mobility and balance
  • muscle weakness and tightness

Symptoms are unpredictable. Some people's symptoms develop and increase steadily over time, whereas for others they are available and go periodically.

  • color blindness
  • eye pain; sometimes created worse when moving the attention
  • flashes of sunshine when moving the attention

These symptoms are the results of optic neuritis, that is inflammation (swelling) of the optic nerve that transmits visual data to the brain. This normally solely affects one eye.

Other visual issues that may occur in MS include:
  • double vision
  • eye pain in each eyes
  • involuntary eye movements (usually from facet to side), called nystagmus

Abnormal sensations

Abnormal sensations are often conjointly a standard initial symptom of MS. this could take the shape of numbness or tingling in numerous elements of your body.

Muscles in your arms and legs may feel unusually weak.
Muscle spasms and spasticity

MS will injury nerve fibres in your brain and spinal twine, which may cause muscles to contract tightly and painfully (spasm). Your muscles may become stiff and immune to movement, that is thought as spasticity.
Pain

Around 1/2 individuals with MS expertise pain, which may take 2 forms:
  • Neuropathic pain - caused by injury to the nerve fibres within the brain and spinal twine. It are often stabbing pain, extreme skin sensitivity or a burning sensation.
  • Musculoskeletal pain -  not caused directly by MS, however will occur if there's excess pressure on muscles or joints as a results of spasms and spasticity.

Mobility issues

MS will have an effect on balance and co-ordination. It will build walking and touring tough, significantly if you furthermore mght have muscle weakness and spasticity.

 you'll expertise problem with co-ordination, referred to as ataxia.
Shaking of the limbs (tremor) is rare however are often severe.
Dizziness will happen late on and may cause you to feel as if your surroundings are spinning (vertigo).

Extreme tiredness (fatigue)

Feeling very tired (fatigue) could be a common symptom of MS that several individuals describe mutually of the foremost troublesome

It is estimated as several as nine out of ten individuals with MS can expertise episodes of fatigue.

People with MS have reported feeling an amazing sense of weariness where even the foremost straightforward physical and /or mental activity looks an amazing struggle to hold out.

Fatigue could also be worse in hot weather, when exercising or throughout illness.
Problems with thinking, learning and designing

Around 1/2 individuals with MS have issues with thinking, learning and designing (known as cognitive dysfunction) within the early stages of the disease. they'll have:

 issues understanding and using language
 a brief attention span
 issues learning and remembering new things (long-term memory is typically unaffected)
 issues understanding and processing visual data, like reading a map
 problem with designing and downside solving – individuals usually report that they grasp what they need to try to to, however can’t grasp the strategy of a way to do it
 issues with reasoning, like mathematical laws or solving puzzles

Mental health problems

Around 1/2 all individuals with MS expertise a minimum of one episode of depression at some purpose in their life.

It is unclear whether or not the depression arises from the injury to the brain caused by MS or owing to the strain of getting to measure with a long-term condition, or both.

Anxiety may also be a tangle for individuals with MS, particularly throughout the beginning of a relapse, as they're naturally anxious regarding the come back of their symptoms.

Some individuals with MS will generally expertise speedy and severe mood swings, suddenly bursting into tears, laughing or shouting angrily for no apparent reason.
Sexuality

Many people with MS lose interest in sex.

Men with MS usually notice it arduous to get or maintain an erection (erectile dysfunction). they'll conjointly notice it takes lots longer to ejaculate when having sex or masturbating, and should even lose the flexibility to ejaculate altogether.

Women might notice it tougher to realize orgasm.
Bladder issues

Bladder issues are common in MS.

These might include:

  • having to urge up frequently throughout the night to pass urine (nocturia)

Constipation

Constipation affects around 1/2 individuals with MS. they'll pass stools abundant less frequently than traditional, and notice this tough.

Severe constipation will cause faecal impaction, where an outsized, solid stool becomes stuck within the back passage (rectum) and begins to stretch the muscles of the rectum, weakening them. this could cause loss of traditional bowel management (bowel incontinence), where watery stools leak out.
