The outcome for me was that I have Benign Fasciculation Syndrome (I get twitchy when I'm tired, stressed, or sleep-deprived), and I'm prone to Sleep Paralysis, as are others in my family.

I also did get tested for C9ORF72 via Genome Medical bc I was terrified that it could have been early stages of ALS. I think a lot of folks share this fear and I really recommend getting tested if you have any family history of that disease. It helped so much to learn that I don't have a pathogenic # of expansions on that gene, which means my kids cannot inherit it either. (A very unkind former family member suggested it, and I developed crippling health anxiety for over a year until I finally got tested.)

Bottom line: Find a good neurologist if you're really worried, and consider testing if that might apply to you. Wishing everyone long & healthy lives.
