Could this be dementia?

[Jennybeans401]

My df is 75 and quite independent despite some mobility problems. He's staying with us at the moment due to renovation at his house.

There were some neighbours talking in their garden until late last night (we could hear because it was boiling with windows open). I fell asleep and my df woke me up at 3am telling me that the neighbours were complaining about me.It was strange so I said they were probably being told to stop talking outside by our other neighbour?? Df made a big deal out of saying that he didn't want me to get into trouble and he was trying to protect me. Very strange!

This evening he got very annoyed with my eldest ds as df talks repetitively a lot and ds had complained. I was trying to talk to df but he was sat with his fingers in his ears and I have been seeing this as totally strange behaviour. Is this the onset of dementia?

Could be anything OP. UTI, vitamin deficiency, psychosis. I'd make a GP appointment first thing in the morning and get him checked out.

He won't see the GP, he doesn't think there's anything wrong or unusual about his behaviour. He gets quite angry about the idea that he might need help.

I don't know much about psychosis but maybe could be stress related?

It could be UTI related. Call the GP and ask for a call back from the Dr and ask for advice. You can't leave a UTI to fester. If he gets aggressive or gets worse I would call the NHS.

If df does have the beginning of cognition difficulties or Dementia, being out of his known environment and out of routine will exacerbate things. Having an infection can also cause confusion. It is often very difficult to get people at the beginning of Dementia to agree to see the GP or have any tests/brain scan to enable a diagnosis.
Is he having problems with his short term memory?

Not so much but he does panic when he can't find his keys or wallet.It's more the personality change that's worrying and the strange idea that my neighbours were talking about me.

He swore when ds complained about the repetitive talking today (didn't swear at ds but got agitated and swore about it).

@Jennybeans401 it can be difficult to pinpoint what is going on when the first signs of cognitive problems start as there could be several explanations, and it can be very scary for the person experiencing it too. The fear can often cause them to react. The repetitive telling of things can be exasperating for others but keeping things calm and giving simple replies helps to prevent him getting cross. He won’t realise he is repeating himself so will get upset if told about it.
Have a look at the Alzheimer’s Society. Website for information on symptoms and coping strategies. Also check he doesn’t have a UTI. It may be something as simple as that.

Yes can be dementia but I would try get UTI test and blood test to rule out an infection as it can really change an older person!
Also, I had a chap who had a turn due to being pre diabetic

Thanks, that's a good idea. I will see if he will get checked.
