| | Re: CPK levels?
My CPK levels have always been somewhat high, which has been attributed to my extensive running, as I was doing several half marathons and training for a marathon. When I first started experiencing ALS symptoms (speech slurring) and the doctor mentioned ALS, I did some research and learned about a similar but much less severe condition called spinobulbar muscular atrophy, SBMA, also called Kennedy's disease. SBMA is characterized by very high CPK levels. However my levels were only slightly above the normal range, while SBMA levels are often several times normal. Anyway there is a genetic test for SBMA, and I requested it, but it turned out I don't have SBMA.
