Makes sense, as Parkinson patients, freeze or tremble, which are both fear responses. I have seen my mother die of Parkinsons. I see a static (permanent) fear response as the straightforward cause for Parkinsons (combined with a helpful personality, which makes it difficult to just snap out of it).
On the other end there were people close by that having seen war, took a life lesson from their fear response: you survive by being alert and by distrusting. They radiated a permanent state of alarm, as the enemy may come when you least expect it.
