RESULTS:
Concussion in adolescence was associated with a raised risk of MS, producing adjusted odds ratios (95% confidence intervals) of 1.22 (1.05-1.42, p = 0.008) and 2.33 (1.35-4.04, p = 0.002) for 1 diagnosis of concussion and >1 diagnosis of concussion, respectively, compared with none. No notable association with MS was observed for concussion in childhood, or broken limb bones in childhood and adolescence.
INTERPRETATION:
Head trauma in adolescence, particularly if repeated, is associated with a raised risk of future MS, possibly due to initiation of an autoimmune process in the central nervous system. This further emphasizes the importance of protecting young people from head injuries. Ann Neurol 2017.

you play more outside => get more concussions => get more MS
you play more outside => get more ticks => get more ... hmmm ? More what ?
Are we that retarted not to question basic things such as these ?
Does anyone have access to the full study ?
