Prevalence of Multiple Sclerosis
The prevalence of Multiple Sclerosis is highest in North America, northern Europe and Southern Australia. In North America, the highest rate is in Southern Canada and northeastern United States. Studies have indicated that early life residence influences the risk of developing multiple sclerosis. These findings suggest environmental factors for the development of the disease, though nothing concrete has been established. Additional evidence suggest genetic factors play a role. Genetic markers have been found in select populations with MS but the mode of transmission and influence of additional genes is not understood.
Diagnosis of Multiple Sclerosis
Diagnosis of Multiple Sclerosis is based on clinical attacks and MRI evidence of typical lesions. The use of MRI for multiple sclerosis has evolved as a valuable tool used to establish an early diagnosis and monitor disease progression.
Types of Multiple Sclerosis
There are typical patterns for the disease course and patients can be categorized into the following groups: Relapsing Remitting Multiple Sclerosis, Secondary Progressive MS, Primary Progressive MS, Progressive Relapsing MS and Neuromyelitis Optica. There are different approaches and treatments for the above listed forms of MS.
