I took care of my dad living with him the last six months of his life. Right before he died he was in the hospital due to pneumonia. He had trouble swallowing due to the dementia. My mother was alive when he was diagnosed but she was in denial and she died almost two years before him. She never mentioned what type of dementia the Dr said he may have. At the hospital they had in his chart he had Alzheimer's dementia but I didn't see many of the Alzheimer's symptoms. Do they use Alzheimer's as a dementia catchall?
Typically from this site Alzheimers follows this pattern :
Symptoms: Difficulty remembering recent conversations, names or events is often an early clinical symptom; apathy and depression are also often early symptoms. Later symptoms include impaired communication, poor judgment, disorientation, confusion, behavior changes and difficulty speaking, swallowing and walking.
Revised criteria and guidelines for diagnosing Alzheimer’s were published in 2011 recommending that Alzheimer’s be considered a slowly progressive brain disease that begins well before symptoms emerge.
Brain changes: Hallmark abnormalities are deposits of the protein fragment beta-amyloid (plaques) and twisted strands of the protein tau (tangles) as well as evidence of nerve cell damage and death in the brain.
This does not seem like a bad idea...if they really can't diagnose things before death, we should be able to have the accurate information afterwards as it may affect our future.
Sorry for your loss!
While it might not matter which type of dementia your father had, you may wish that you could know what to expect in your future. I can understand this. For what it's worth, forgetting how to swallow is, as I understand it, an AD symptom.
