My 78 year old Mother has dementia and has not talked much this past year. Three days ago, she started making the crackling sounds when she breathes, due to her difficulty swallowing. She has no fever. She is eating. She takes oxygen as needed - as of a day ago. For the past three days, she has been talking - so much more than the past year. This is wonderful and sweet, but I am mystified as to why. She does say random things, but she is also able to respond to questions. It is almost like her brain has been asleep this past year as she talked so little. Anyone else experience this with their loved one?
