1.Relapsing-Remitting MS
Relapsing-Remitting MS is characterized by acute events, but brief neurologic dysfunction (recurrent emphasis or attacks), which may be followed by partial recovery or clinical recurrence. Its characteristics may vary both in type and in severity of the disturbances of sensory function to complete loss of motor function. In Relapsing-Remitting MS neurological problems may persist, but are stable by definition, this means that it can not get worse between acute episodes of neurological dysfunction. Unfortunately, IMR has limited value in giving individual diagnoses people with Relapsing-Remitting MS. The results of recent studies suggest that IMR data may be valuable for a strategy to remove inflammation.
• Frequency: about 85% of cases.
2.Primary-Progressive MS
People with Primary-Progressive MS shows a progression from its onset, with occasional periods of exacerbation and remission. The essential element of the clinical course of MS, it is a nearly continuous worsening condition, with minimal fluctuations, but without distinct recurrent states.
• Frequency: about 10% of cases.
3.Secondary-Progressive MS
Secondary-Progressive MS occurs in people with Relapsing-Remitting MS, when there is a gradual progression of disability, with or without occasional recurring, minor remissions, and plateau.
• Frequency: Weinshenker and colleagues determined that 41% of people with MS - relapsing relapsing form developed in 6 to 8 years after onset secondary progressive form and 58% in 11 to 15 years.
4.Progressive-Relapsing MS
Progressive-Relapsing MS is relatively rare and is characterized from the start by a progressive evolutionary stages of acute recurrent clear, with or without full recovery periods between recurring phases is characterized by a continuous progression.
• Frequency: about 5% of cases.
5.Benign MS
Benign MS patient who kept fully characterize neurological function at 15 years after onset. Benign MS does not worsen over time and does not lead to permanent disability. Benign MS can be identified if the patient suffers from minimal disability 10-15 years after onset of disease or whether it was initially diagnosed with relapsing-remitting multiple sclerosis. Benign MS is characterized by less severe symptoms at onset.
• Frequency: Between 15% and 20% of people with MS have this form. Diagnosis can be made retrospectively.
6.Malignant MS
Malignant MS is described as a disease with a rapidly progressive clinical course, evolved into significant neurological disability or death at a relatively rapid onset.
What is the prognosis?
Evolution of MS is highly variable and unpredictable. Despite all the studies is not yet possible to predict a patient's prognosis at diagnosis. However certain factors have been identified with which we can estimate the clinical course of the disease. For example, a long remission after onset, and initial appearance of sensory symptoms indicate a more favorable evolution.
Most people have a negative impression about MS and people with MS and their families believe that this disease usually always evolves into a severe disability. MS is not fatal, although some people with severe disability may develop serious infections that can be life-threatening.
People with MS can have a relatively normal life if they accommodate.
