Multiple sclerosis is now a global disease. But it is more common among people living in northern latitudes, the developed West. Also women are more affected, according to the new MS Atlas brought out by the World Health Organization and the London-based Multiple Sclerosis International Federation.
The atlas released Wednesday summarizes information on the disease in 112 countries, none of which were free of the disease, CBC reports.
The study confirms it is not a scourge found only in the more developed northern and western countries. Its presence is truly global.
MS is a neurodegenerative disease that attacks the brain and spinal cord, and can lead to paralysis and sometimes blindness.
Some people with MS experience little disability during their lifetime. But up to 60 per cent are no longer fully able to walk 20 years after onset, which has major implications for their quality of life and costs to society, the report said. Symptoms appear around 30 years of age on average.
The Atlas of MS reveals how these implications impact women more than men, by at least two to one, at an age when they are starting a family and developing a career, said Dr. Benedetto Saraceno, director of the WHOs department of mental health and substance dependence.
Countries reporting the highest estimated prevalence, or total number of cases of MS at a particular point in time, were:
Hungary at 176 per 100,000
