Symptoms such as agnosia can accelerate quickly, but it's also possible a medication change or an infection such as a UTI is setting this off. I'd at least check with his doctor so that they can tell you if he should be seen or if they think it's a natural progression, given is stage of AD.
Sometimes some trauma can cause the agnosia to get worse. Sometimes it is the stage as it gets worse. At some point, the situation will get worse for a short while and then it will stablize for a long while. For example, my FIL has severe stage of Alzheimer's and almost once a year or once every 6 months, he would decline a little bit and then get stable. For example, he stopped walking in May but he has been adjusted to get used to the wheelchair now.
Medications can cause side effects as well. So check with the doctor for advice. It does get worse suddenly and then it wil stay stable for a long while. Usually the agnosia gets worse slowly once a year. It would decline a littie bit once or twice a year and then it would stay stable/baseline for a long while until the next episode.
Any trauma such as hospitaliziation can make him decline faster.
Dementia cannot be cured so it will get worse slowly.
Hello, Nursling, I'm sorry you are facing this situation with a beloved parent.
Your mother will need some help as the days go on. Your distance from them makes it almost imperative that she find assistance, and soon.
My father, who died after a relatively short (3 months) but very intense bout of vascular dementia, decided my mother needed to leave; she was a stranger, he said, and she kept watching him. He would not let her sleep in their bed. When she tried to sleep on the couch, he would shine a flashlight on her. If he did not think she was a stranger, he grew anxious if she was not at all times in his presence. It broke my mother's heart. The doctor finally told the family to remove my father from the home, because my mother was getting ill from the situation of trying to appease him. She lost about 30 pounds during this period of his growing agitation.
The nighttime agitation was the pits. Sundown syndrome was not generally discussed at the time (1993), and we only learned the name for the problem once he had been hospitalized. The problem here is that your father might up and lock her out of the house. Then who knows what might happen. And she might hurt herself trying to mollify him. She can't handle this alone.
Depending on the kind of dementia your father has, his agnosia might come and go a bit, though I agree with Nina that these things tend to happen in phases, where there is a period of significant change and then a period of stabilizing.
I hope you come back to the site often and find help here. I know I do! My elderly mother lives with us now. If only such technology had been around when my father was sick and dying in 1992 to 93.
Very best wishes to you,
Agnosia, one of the “4 A’s of Alzheimer’s disease,” is the inability to correctly interpret signals from a person’s five senses. Symptoms of Alzheimer’s disease present differently in each individual, at different rates and on different timelines. Further, because of the progressive nature of the disease, symptoms that seemed mild at first, even for a relatively long period of time, are likely to increase and worsen. However, Alzheimer’s disease progresses at a slow rate; sudden or acute changes in symptoms may signal other issues, such an illness, infections, or medication side effects. It is recommended that you report these changes to your father’s physician for a comprehensive evaluation and assessment.
