Arthritis/Enthesopathies.

Family History
My grandmother was never diagnosed, but she (and her father) were the line of descent.
My mom was misdiagnosed until 2016.
My aunt (mom’s sister) died of complications of HD in 2019.

2003: Joint pains, enthesopathies – elbows first (medial and lateral epicondylitis).

2005: Restless leg symptoms. Heart rate low.   I literally am losing IQ points. I begin to feel it.

2010: Concentration and ADHD-like symptoms. First tendon ruptures (hamstring and obturator internus, undiagnosed until 2017). Quit running.

2012: Numbness and impaired coordination and proprioception.  

2014: Irritability and even more serious concentration and memory issues. Couple of household accidents (burns, mostly). Altered cooking methods.

2015: Joint/tendon issues increase, coordination problems. Beginning of chorea.

2016: Genetic test for HD, positive.  Fine motor impaired: typing, zipping, mouse use.  More chorea.

2017: Diagnosed with Huntington’s Disease.  Balance problems.  Require 10+ hours sleep.

2018: Unable to work – concentration is off.  Stumbling and dropping things more often. Easier to do a handstand than tie my shoes. Not all progression is linear, or like you’d expect. Quit working.

2019: A couple of falls, walking is more difficult when physically stressed.  So is thinking. Quit cycling (balance problems).

2020: Covid-19. Noticeable increases in movement, decreases in fine motor coordination and balance. Still doing morning stretches and some exercise. Enthesopathies are the primary limiters.

2021: More facial tics. It’s harder to hide. Putting on jewelry is difficult. Out of sight is literally out of mind. I forget I’m in a zoom meeting after muting. At least I wasn’t hosting it.
