She starts by saying she's scared at 5 o'clock or so and then her muscles start to constrict in her arms and she complains of pain around her heart (give nitroglyceran for that often) and difficultly breathing. She's repeating statements like, I can't breathe, over and over, then says another sentence like, take me, take me, etc... You can't talk to her to get her to change the situation or calm down. I've tried nebulizer meds and symbicort inhaler and oxygen concentrator which she won't breathe through her nose to benefit and all of her pain meds on schedule only. I give her serquel, trazadone, and holdol on a regular schedule, also. I'm careful not to overload her with drugs but when these attacks happen nothing helps...nothing until I give her xanax at bedtime. So we have all evening to get through until then. It's tough on the whole family as it upsets everyone. She's been diagnosed with sundowning. Any advice, could this be Alzheimers, or Parkinson's as well. With everyone's experience please let me know what you think or what might help! Thank you!
