Sometimes by reading descriptions of various kinds of dementia you can get a sense of what might apply to Dad. The Alzheimer Association website contains such descriptions. At this time there is no blood test, urine test, or other such way to determine kind of dementia. It can be accurately determined via autopsy, but that isn't very useful for day-to-day considerations!
Weight loss is fairly common in many types of dementia, as is dysphasia.
You mentioned that he has dysphasia which is difficulty swallowing, but at the same time you said he eats well. I think you possibly mean aphasia which is loss of speach.
Loss of weight is very common with both heart failure and COPD because the person can't eat and breath at the same time.
Try contacting your local health department and see if they will send a nurse out to evaluate him. They may be able to provide some in home care at least to get him bathed. I suspect by now it is simply too much effort. He may also be a candidate for hospice if his condition is advanced enough.
Do you have POA and advanced directives in place because if you don't he would now be considered incapable of making those decisions for himself.
At the slightest excuse get him transported to the ER and refuse to take him back because he is too uncooperative for you to manage. He needs to be in some kind of facility where they have the training to get things done. I am sure he is going to refuse and make all kinds of nasty accusations to you but it may be the only way. Please come back and tell us how you are getting on. You are not the first person with this problem
My LO's primary doctor diagnosed her with Vascular Dementia in her office based on medical history, mini office exam, symptoms and examination. She was right too, as a follow up with a Neurologist and MRI confirmed. They may also recommend a neuropsychological evaluation, but, it's rather involved and my LO was not up for it. Even after all the testing, they still can't be 100% on what is causing the dementia, such as Alzheimers, Vascular, Lewy Body, Frontal Lobe Dementia, etc.
The kind of things that looked at with my LO was how fast it hit her and her medical conditions like hypertension andType II diabetes. The MRI did show that she had had multiple strokes. Would your dad agree to an MRI?
