I'm looking after my dad who is yet to be diagnosed. He has suffered with poor memory for over 10 years but in the last 18 months it has got rapidly worse. He was referred to OPMH last summer & in September they diagnosed him with MCI. They were quite happy to discharge him & for me to get another referral should he deteriorate. I said I wasnt happy with that & so he was seen again in March & referred for a brain scan which he had in early May and we should get results at end of June. In the meantime I am about to go ona 2 week holiday and so my brother who lives about 3 hours away has agreed for my dad to go stay with him. I moved my dad in with me in March as he was unable to be on his own as he wasnt eating properly. So this morning I said we were taking him to my brothers and he threw a toddler like tantrum...kicking the bags I packed & throwing his shoes - fortunately not at anyone. I met my brother half way. We had some lunch together & then they set off together & I returned home. At 7.00 this evening I get a phone call from my brother saying my dad wants somethings sorting out. Dad becomes agitated on the phone - he usually does around this time anyway. He wants to know how he got there, why he was there. I told him how and then said it was because I was going on holiday.... then he got more agitated. I admit I didn't tell him the reason before I took him otherwise he would've refused to go. It got more heated with him telling me very sarcastically to have a nice time. To which I replied I will & then I put the phone down. My brother phoned me later to say that he cant believe how bad dad has got. He constantly asks the same questions over & over again. He cant put any logic around time & places. When hes at home with me and he acts this way we find the best way to deal with him is to leave him on his own in whichever room hes in........but now I feel like I'll never be able to go on holiday again if this is how he is going to be.... Has anyone else had to deal with this behaviour? Is it a trait of dementia? Dad has also suffered with high blood pressure for over 15 years & has recently been diagnosed with Atrial fibrillation.
