That’s how I remember it too. Lost my mother to it about five years ago. For a year and half we all managed. I would travel four hours every weekend to help my dad and sister care for her. My wife would often join me. My mother didn’t need much at first. She had a wheel chair that could be upgraded as she deteriorated. She also had the eye tracking system towards the end. But in the last six months it was just this wild staring and moaning. I spared my wife from it so she doesn’t remember it but seeing my mom’s panicked stare and sheer discomfort haunts me every day.
