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.
Microbial infection has also been implicated as an aetiological factor in MS. Two hypotheses have been developed to back the theory; hygiene hypothesis and prevalence hypothesis. With hygiene, disease presents after a secondary exposure to a given agent with primary contact being protective. In the case of prevalence, the disease is as a result of a microbe more common in areas where MS is outstanding with no symptom manifestation. Certain viral infections have been associated with MS including herpes, Epstein Bar Virus, mumps and measles.
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.
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.
Four main clinical courses exist. These are the progressive relapsing, the relapsing remitting, and the primary and secondary progressive. All have varying features and varying degrees of severity. The secondary progressive is the commonest and affects about 65% of individuals with the disease. The relapsing remitting is characterized by recurrence after treatment.
Generally, there is no way to prevent the attacks of MS. As such, the primary aim of therapy is to restore function after an attack, prevent new attacks and avoid disability. Interferon beta or glatiramer may delay disease progression in some cases of secondary progressive MS. Viral infections such as flu may trigger relapses, so are the first few months after delivery in women. Prompt treatment of such infections is recommended.
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.
