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.
The role for microbes is backed by two theories namely the hygiene theory and the prevalent theory. In the hygiene theory, a microbe will only result into MS on a second exposure. The first exposure causes an immunological reaction that is protective. In the prevalent theory, it is said that certain microorganisms are associated with geographical areas known to have a high prevalence of the condition and thus are thought to play a role.
Several risk factors are thought to greatly contribute to worsening of MS. These factors include occupational exposure to toxins, smoking, hormonal treatments, stress, diet and vaccination among others. Avoiding these factors and behaviors is said to lower the risk of the condition significantly.
In terms of the pathologic presentation, there are three main features that have been identified. These include inflammation, damage and formation of lesions on myelin sheaths. These processes all contribute to the breakdown of the protective tissues and thus cause the characteristic symptoms. Autoimmune reactions at these sites are thought to play a prominent role.
There are four clinical courses that have been described to date. These include the relapsing remitting, the primary and secondary progressive and the progressive relapsing type. All these have specific features that distinguish them. For example, the relapsing remitting is intermittent in nature.
Whenever an attack occurs, the initial priority should be to restore the CNS function and to prevent subsequent attacks. Efforts to avoid permanent disability should also be made. A number of pharmacological agents have been found to be helpful in delaying the progression of disease. The leading agents are beta interferon and glatiramer. Prompt treatment of flu particularly in the months following delivery in women.
High temperatures have been found to be an exacerbating factor in these patients. They accelerate the deterioration of the nervous system especially for the components that have already been affected. It is recommended, therefore, that affected individuals use air conditioners whenever possible. They should avoid using hot tubs or hot swimming pools. As can be seen in all these situations, all MS prevention strategies revolve around avoidance of exacerbating factors.
