Multiple sclerosis or encephalomyelitis disseminata is a condition that affects the spinal cord and brain. The component that is affected is mainly the protective cover or myelin sheath. One the sheath has been damaged, the function of the nervous system is compromised and this results in a number of signs and symptoms that may manifest both psychologically and physically. In a number of patients, these signs and symptoms resolve completely while in others it may result in serious complications. MS prevention aims at avoiding both the symptoms and complications in susceptible individuals.
The aetiological factors of this condition are a combination of both genetic and environmental factors. Certain genetic variations have been shown to increase the risk of MS. The risk is higher in relatives of the affected individual with probability increasing among those very closely related. Identical twins have the highest chance of being victims, followed by fraternal twins, siblings and step siblings in that order. Predisposition is ten times higher when both parents are victims.
There is strong evidence to suggest that microbes may play a role in the aetiology. This is backed by two theories. The first of these theories is the hygiene hypothesis. In this theory, the disease occurs after a second exposure to a certain microbe. The first exposure to the microbe results in a protective reaction. The second theory is the prevalence hypothesis which purports that certain types of microbes are isolated in persons living in areas with a higher prevalence of MS as compared to those living in lower prevalent areas.
A number of lifestyle behaviors are thought to help in the propagation of the condition. Doctors say that modifying these unhealthy habits will significantly lower the risk. They include, among others, smoking, stress, diet, occupational factors (exposure to toxins), vaccination and hormone intake.
Pathologically, there are three main features of MS including formation of lesions, inflammation and damage to myelin sheaths. Interaction of these characteristics results in breakdown of nervous tissue and hence physical manifestation of signs and symptoms. Damage is also believed to be caused by an autoimmune reaction in the body.
Four clinical courses exist; relapsing remitting, secondary and primary progressive and progressive relapsing. The relapsing remitting form is characterized by alternating periods of disease manifestation (relapse) and asymptomatic periods (remission). Secondary progressive occurs as a later stage of relapsing remitting type in 65% cases.
The priority after an episode of CNS attack should be to rehabilitate the affected individual and to prevent secondary attacks. Disability should be prevented if possible. Interferon beta and glatiramer are two drugs that have become very useful in the control of progression. There is a strong recommendation for prompt treatment of infections as these are a significant risk factor.
High levels of temperature have been established to be a factor that worsens the signs and symptoms. They lead to the deterioration of the nerves that have already been affected and for this reason they should be avoided at all costs. If air conditioners are available, they should always be put in sue. Hot swimming pools and tubs are to be avoided. MS prevention, as seen here, involves the removal of any exacerbating factors.
