Today I had my Visit #04 and second spinal tap.
I think they modified the lists I memorized so that not all 12 words were there... that kind of messed me up - I'll have to practice some more.
The first lumbar puncture I had last year went pretty smoothly. This one was more complicated - the neurologist kind of brushed a nerve or something with the needle and I got what felt like an electric shock going down my leg and fainted. She said we could quit but I told her to try again and the second attempt was successful at extracting 18mL of cerebral spinal fluid. She was impressed with my commitment and pain tolerance.
Neurology exam didn't find any symptoms of PD, but did reveal I have some dead reflexes in one foot.
It's embarrassing how much they thank me for going through this.
Bonus: PPMI coffee cup and a frame-able certificate of appreciation.
