Читать книгу AutoBioPhilosophy: An intimate story of what it means to be human - Robert Smith Rowland - Страница 9

The ‘sclerosis’ in multiple sclerosis or MS refers to lesions resulting from damage done to the sheaths encasing the nerve cells in the brain and spinal cord. This damage affects physical coordination, speech, ability to concentrate, memory and more. Maybe all diseases are strange, travelling as covertly as spies and silently infiltrating our systems. What makes MS especially mysterious is that it seems to result from a mutiny in the autoimmune system. Rather than do its job of protecting the body, the autoimmune system revolts and attacks. But not only that:

 women get it more than men;

 you’re more susceptible to it the further your origins lie from the Equator;

 there is no available cure; and

 its causes are unknown.

Unknown but not unguessed at. The medical literature points to both genetic and environmental factors, though the evidence for either remains inconclusive. It is not a lifestyle disease. Nor is it considered heritable, even though there’s some debate about your increased likelihood of getting it if you’re related to a sufferer. As Colin’s son, I am acutely aware of this possibility, though I’ve never shown any symptoms and have reached an age at which they’re less likely to appear. That does, however, raise the question of just how closely related he and I are.
