Mom put my fingers in her mouth last night, like a baby would do. Is this common?

Just days before Dad passed with Parkinson's, maybe a bit longer, he did a sort of 'fake eating' where he would reach out into the air and bring imaginary food to his mouth, then chew. If I remember correctly, most of the time his eyes were closed then, though he was in an upright position in his wheelchair.

I'm not that familiar with Lewy Body/Parkinsons related dementia. I am sorry to hear of your mother's progression. I have read that once the patient is in the final stages of dementia, they seem to be quite similar. I know it's tough. Is your mother on Hospice?

My LO has Vascular dementia with possible AD too. Her doctor diagnosed her with Profound Dementia over a year ago and she's progressed substantially since then. He described it as her mind returning to infancy, so that she has the mental ability of a young child or infant. At one time, she would call out, mama, daddy, but, that stopped and she is no longer verbal. She seems to be in a pre-verbal phase now. I'm not sure what to expect from here.

Does your mother seem to be awake or is she mainly sleeping?
