The many faces of the sclerosis
Multiple Sclerosis can be divided into 3 main groups (namely sclerosis, primary progressive sclerosis and secondary progressive sclerosis).
In addition, there is a subgroup for occlusal sclerosis, called benign (benign) sclerosis.
It is usually only after 5 to 10 years of illness that one can comment on the prognosis of the individual patient.
In 80% of all sclerosis sufferers, the disease starts with a disease attack where the symptoms disappear completely or partially.
People who have sclerosis experience repeated attacks (attacks) from different parts of the nervous system. It is thus said that the symptoms are disseminated (disseminated) in time and place. The individual attacks can thus have widely different symptoms as they come from different places in the nervous system.
Secondary progressive sclerosis:
60 - 70% of people who suffer from sclerosis in the course of 5 - 10 years switch to a course of smooth progressive disability. Most often, these individuals will continue to experience attacks.
Primary progressive sclerosis:
10-15% of all sclerosis sufferers have primary progressive sclerosis.
People who have primary progressive sclerosis rarely experience true attacks; but they may nonetheless occur. Unfortunately, this group is experiencing a steadily progressing disability.
Benign (benign) sclerosis:
After one or two attacks with complete cessation of symptoms, 20% experience no significant worsening of the disease and people develop no permanent inability to live, which means that they can live an ordinary life without disability. This variant of the disease is called benign sclerosis.
Initially, Benign Multiple Sclerosis usually causes less severe symptoms (such as sensory disturbances) and can only be safely diagnosed when 10 - 15 years after the onset of the disease, there is only a minimal lack of mobility and when the disease course is initially characterized as inappropriate.
Today, the cause of multiple sclerosis is unknown.
Sclerosis is not hereditary, but the prevalence is more prevalent in family members of sclerosis patients than in the rest of the population and more frequently in people with certain types of tissue.
Thus, it is believed that the cause is probably due to the coincidence of several factors, for example a hereditary factor combined with an environmental factor. It may be due to a virus that, together with a factor in the immune system, triggers the disease
