My MDS prescribed Amantadine but it hasn't helped much. My understanding is that freezing is a cognitive issue in that it is a function of how our brain interprets visual cues. As a person with PD the response to a freezing episode is situational and based on experience. For example, going through doorways at a commercial building always triggered an embarrassing freezing episode for me, with entering a building more problematic than leaving one (which is really pretty weird). The process I have used to overcome this issue is actually fairly simple and it works . . . most of the time 🤔. I have noticed that it fails whenever I am in a hurry and start rushing. Anyway, this link has info that has helped me to overcome freezing quite a bit:

Youtube also has a tremendous amount videos with information on how to "thaw out" from a freezing episode.

"Skills and wellness," with Nathan. He has shorter videos, 15 minutes, that help.

I have cervical dystonia and dysphonia. I had botox injections for each. The stress of getting to a doctor two hours away outweighed the benefit of the shots. They helped for about two weeks every three months. Bummer.
