My mother was diagnosed 3.5 years ago with Parkinson's, which has been managed pretty well. Balance is really the main issue. However, 2.5 months ago she had a massive change resulting in memory & confusion issues. It really felt like over night. There were several MRI, PET Scans, blood work and nothing showing infections (other than a UTI that was treated), stroke, seizure, nor signs of Alzheimer's. She's currently in the hospital after a serious bout of delusions, paranoia and irrational distrust of myself and my dad (which never occurred before) and it was truly a safety risk for her. The neurologists now feel she has Lewy Body Dementia. My dad is her caregiver and I live 5 min away with my family. I feel devastated we may never get her back (cognitively), scared what the future my hold and just plain sad she's in this state. Such a ruthless disease
