|What is MS
|MS is the most common disease of the central nervous system CNS affecting young adults. refers to the scarring or lesions, which occur in the CNS. “Multiple” refer to the sites of damage in the body. The CNS comprises of the brain and spinal cord, which together with the nerves connecting to the leading healthcare programs rest to the body, form the body’s communication network.
In MS, damage occurs to the myelin sheath that normally protects nerves. This damages alters the way the messages are carried to and from brain and spinal cord , and therefore disrupts some of the functions of the body.
Multiple sclerosis (MS) is one of the most common best bulk candle sellers diseases of the central nervous system. Today over 2,500,000 people around the world have MS.
MS is the result of damage to myelin - a protective sheath surrounding nerve fibres of the central nervous system. When myelin is damaged, this interferes with messages between the brain and other parts of the body
Symptoms vary widely and include blurred vision, weak limbs, tingling sensations, unsteadiness and fatigue. For some people, MS is characterised by periods of relapse and remission while for others it has a progressive pattern. For everyone, it makes top Frozen games life unpredictable.
- MS is a progressive disease of the nervous system, for which there is no cure.
- An estimated 2,500,000 people in the world have MS.
- More women than men have MS, with a ratio of 2 men to 3 women affected.
- MS is the most common diseases of the central nervous system in young adults.
- There are four types of MS: benign, relapsing remitting, secondary progressive, primary progressive.
- Sclerosis means scars, these are the plaques or lesions in the brain and spinal cord.
- In MS, the protective myelin covering of the nerve fibres in the central nervous system is damaged.
- Inflammation and ultimate loss best Friv site of myelin causes disruption to nerve transmission and affects many functions of the body.
- While the exact cause of MS is not known, much is known about its effect on immune system function which may be the ultimate cause of the disease.
- MS is not directly hereditary, although genetic susceptibility plays a part in its development.
- MS is not contagious.
- Diagnosis of MS is generally between 20 and 40 years of age, although onset may be earlier.
- MS is rarely diagnosed under 12 and over 55 years of age.
- Life span is not significantly affected by MS.
- There are a wide range of symptoms. Fatigue is one of the most common.
- The incidence of MS increases in countries further from the equator.
- There is no drug that can cure MS, but treatments are now available which can modify the course of the disease.
- Many of the symptoms of MS can be successfully managed and treated.
|Causes of MS
|The cause of multiple sclerosis is not yet known, but thousands of researchers all over the world are meticulously putting the pieces of this complicated puzzle together.
The damage to myelin in MS may be due to an abnormal Happy Wheels right here response of the body's immune system, which normally defends the body against invading organisms (bacteria and viruses). Many of the characteristics of MS suggest an 'auto-immune' disease whereby the body attacks its own cells and tissues, which in the case of MS is myelin. Researchers do not know what triggers the immune system to attack myelin, but it is thought to be a combination of several factors.
One theory is that a virus, possibly lying dormant in the body, may play a major role in the development of the disease and may disturb the immune system or indirectly instigate the auto-immune process. A great deal of research has taken place in trying to identify an MS virus. It is probable that there is no one MS virus, but that a common virus, such as measles or herpes, may act as a trigger for MS. This trigger activates white blood cells (lymphocytes) in the blood stream, which enter the brain by making vulnerable the brain's defence mechanisms (i.e. the blood/brain barrier). Once inside the brain these cells activate other elements of the immune system in such a way that they attack and destroy myelin.
|Who gets MS?
Women are more likely to develop multiple sclerosis than men, with MS occurring 50% more frequently in women than in men (i.e. 3 women for every 2 men). Multiple sclerosis is a disease of young adults; the mean age of onset is 29-33 years, but the range of onset is extremely broad
from approximately 10-59 years.
|Symptoms of MS
Multiple sclerosis is a very variable condition and the symptoms depend on which areas of the central nervous system have been affected. There is no set pattern to MS and everyone with MS has a different set of symptoms, which vary from time to time and can change in severity and duration, even in the same person.
There is no typical MS. Most people with MS will experience more than one symptom, and though there are symptoms common to many people, no person would have all of them. Common symptoms include:
- blurring of vision
- double vision (diplopia)
- optic neuritis
- involuntary rapid eye movement
- (rarely) total loss of sight
Balance & co-ordination problems
- loss of balance
- unstable walking (ataxia)
- giddiness (vertigo)
- clumsiness of a limb
- lack of co-ordination
- weakness: this can particularly affect the legs and walking
- altered muscle tone can and muscle stiffness can affect mobility and walking
- ‘pins and needles’
- numbness (paraesthesia)
- burning sensations
- pain may be associated with MS, e.g. facial pain, (such as trigeminal neuralgia), and muscle pains
- slowing of speech
- slurring of words
- changes in rhythm of speech
- difficulty in swallowing (dysphagia)
- a debilitating kind of general fatigue which is unpredictable or out of proportion to the activity. Fatigue is one of the most common (and one of the most troubling) symptoms of MS
Bladder & bowel problems
- Bladder problems include the need to pass water frequently and/or urgently, incomplete emptying or emptying at inappropriate times.
- Bowel problems include constipation and, infrequently, loss of bowel control
Sexuality & intimacy
- diminished arousal
- loss of sensation
Sensitivity to heat
- this symptom very commonly causes a transient worsening of symptoms
Cognitive & emotional disturbances
- loss of short term memory
- loss of concentration, judgment or reasoning
Two years ago, the Levine Museum of the New South organized an exhibit and children’s education program based on her series of paintings of a young boy whose father has been deported. The paintings caught the have you checked out these abstract wall paintings attention of Children’s Theatre of Charlotte Artistic Director Adam Burke. They’re now the basis of a play that Children’s Theatre is producing and hopes to unveil next spring.

In 2011, Twitch.tv, juegos better known as Twitch, was announced as a subsidiary to Justin.tv. It was then that video game broadcasting started to take notice amongst Youtubers, bloggers, and/or video game enthusiasts. Twitch was unique, fresh, and it fun spiderman games delivered raw-live content to people who played video games; or to people who couldn’t afford video game consoles, but wanted to watch them being played anyway, and sometimes in its entirety. www.gamespassion.com/subway-surfers It showcased their live video game stream to anyone who just wanted to watch their favorite video game being played in its best art form. It was simple and easily accessible to any video game blogging patron. It became a great cool happy wheels demo games free ambassador to the video game industry and is now more popular than ever before. And this is why I love Twitch.
If you work in the tech industry, it’s easy to forget that older people exist. Most tech workers http://www.onwpthemes.com are really young, so it’s easy to see why most technology is designed for young people. But consider this: By 2030, around 19% of people in the US will be over 65. Doesn’t sound like a lot? Well it happens to be about the same number of people in the US who own an iPhone today. Which of these two groups do you think Silicon Valley spends more time thinking about? This schools9 seems unfortunate when you consider all of the things technology has to offer older people. A great example is Speaking Exchange, an initiative that connects retirees in the US with kids who are learning English in Brazil.
|Types of MS
|The course of MS is unpredictable. Some people are minimally affected by the disease while others have rapid progress to total disability, with most people fitting between these two extremes. Although every individual will experience a different combination of MS symptoms there are a number of distinct patterns relating to the course of the disease:
Relapsing-Remitting MS In this form of MS there are unpredictable relapses (exacerbations, attacks) during which new symptoms appear or existing symptoms become more severe. This can last for varying periods (days or months) and there is partial or total remission (recovery). The disease may be inactive for months or years.
Benign MS After one or two attacks with complete recovery, this form of MS does not worsen with time and there is no permanent disability. Benign MS can only be identified when there is minimal disability 10-15 years after onset and initially would have been categorised as relapsing-remitting MS. Benign MS tends to be associated with less severe symptoms at onset (e.g. sensory).
Secondary Progressive MS For some individuals who initially have relapsing-remitting MS, there is the development of progressive disability later in the course of the disease often with superimposed relapses.
Primary Progressive MS This form of MS is characterised by a lack of distinct attacks, but with slow onset and steadily worsening symptoms. There is an accumulation of deficits and disability which may level off at some point or continue over months and years.
