My mother was officially diagnosed with chronic-progressive MS at the age of 40 (much later than average). She had begun experiencing the symptoms of MS when she was 20 (though at the time, in 1974, had no idea it was that), immediately following a car accident in which she had flown through the windshield, leaving glass in the top of her head that had to be removed. The doctors had figured her symptoms were a result of the accident, and so explains the 20-year gap between the onset of symptoms and the diagnosis.

We have always wondered if there are other cases of people out there like her, who were involved in some type of head trauma that could have resulted in the onset of MS? There are studies that suggest a link, and others that negate this link. Perhaps this information could lead to new ways of studying the disease.

Any information is appreciated. Stay strong♥
