I found out I have very high cholesterol this year. Because of my age and prior physical fitness I had never been tested before. One doctor wished to put me on cholesterol lowering drugs, while another told me no reason for that because my bp is so low. I'm happy to not have to keep track of one more pill.
I've read that cholesterol is neuroprotective. I've also read that statins can cause their own neurological issues in some cases. As high cholesterol is likely not what's going to finish me off, I am not prepared to take a risk.
I think the above posted research is important. It's exciting that researchers are making connections and new discoveries to build further research onto MND. But, as others have stated, it's too early to start making adjustments based on it.
