Multiple sclerosis (MS) is a disease of the central nervous system – it may affect the brain, spinal cord and/or optic nerve. It is a very variable condition and the symptoms depend on which areas of the central nervous system have been affected. There is no set pattern to MS and everyone with MS has a different set of symptoms, which vary from time to time and can change in severity and duration – even in the same person. SOURCE – www.msqld.org.au


We do not yet know the answer to this question. The current hypothesis is that the disease appears in those individuals who have a genetic predisposition to react to some infectious agent in the environment such as a virus or bacterium. This means that the disease is not genetically transmitted in the same way as hair or eye colour, for example. There seems to be a combination of genes that makes one person more susceptible to the agent(s) than someone else with a different genetic makeup. While several different viruses and bacteria have been studied for their possible role in MS, the trigger(s) have not yet been found. Environmental and psychological factors may play a part that we do not yet understand. We do know, however, that MS is not a contagious disease and you do not need to be concerned about transmitting MS to those around you. SOURCE – www.msqld.org.au
