Dear
@Gill M
I will try and answer your question by relating my own situation. I will assume your husband retains capacity so his decision will be accepted. Please be clear this is only my personal experience. I only relate it to you in case your husband refuses to attend and you then end up wondering what to do for the best. I got into that situation and had months wondering what to do.
Mum attended the Memory Clinic in 2015 and was diagnosed with Mild Cognitive Impairment. Since then her memory has become really bad, I am confused at times as being her dad, mother or her deceased husband (my dad). Other matters are slowly becoming apparent, without a doubt mum has Dementia, as yet officially undiagnosed. Despite the best efforts of our GP mum refuses to go back to the Memory Clinic. “If I am going dolally I do not want to know” was screamed at me in the car in the GP car park.
Mum has a history of high blood pressure, heart disease and had major heart surgery in the past. I had many months worried I should pressure mum to attend the Memory Clinic, was she missing out on treatments, etc. In the end I made peace with myself after a chat with the GP and a counsellor at the carers group, I attended before lockdown without mum. Be clear there are no guarantees I am right, but I had to accept certain basic points.
Firstly mum’s heart problems and high blood pressure meant she is most likely suffering from developing Vascular Dementia. There are no treatments available except trying to control her blood pressure. Mum had capacity when stating the above. Likely now fluctuating capacity, but her wish is unchanged though I now no longer raise the matter.
Secondly even if she had say Alzheimer’s the treatments available do not work for everyone, for those they do the effects vary and reduce over time. My mum relies on me as her carer. She trusts me, I work full time to give her reassurance, deal with the problems of memory loss, arrange and get her to all appointments, ensure she eats well and drinks adequate fluids. On relationship of mutual love and trust is mum’s best defence in the fight against her Dementia. I could not risk destroying that forcing her back to the Memory Clinic, when the potential upside was little if anything. I gave up work early to help mum. I had to accept I could only help her fully if for now we face her Dementia together how she wants to.
Thirdly I do not need a diagnosis of Dementia to be able to claim Attendance Allowance when that time arrives. It would have helped get us into a day centre but since Covid19 they are gone, as is the carers group, who kindly let me attend without my mum, who would never have agreed to go.
So personally I believe (as best I can) not going back to the Memory Clinic has not seriously impacted on my mum. I have respected her wishes, long held before the signs of Dementia showed, I am not totally happy even now but I love my mum, I will do her Dementia journey the way she wishes to. I can only speak for my own situation and I have tried to be honest. If your husband has say Alzheimers, going to the Memory Clinic could open up some medication, which might do some good for a period of time. What I am trying to say is if he refused to go, your love and relationship with him would still be in place and those factors are the most important in determining how his future goes. I am genuinely happy that there are medications available that work for some people. However I did an Internet course with the University of Tasmania, which went into some detail on the effectiveness of such drugs, it made sobering reading. As said earlier they only work for some, to varying degrees and for varying amounts of time.
If your husband agrees to attend the Memory Clinic it can do him no harm. If he is diagnosed with Vascular Dementia I do not believe there will be any new treatment available, just an emphasis on controlling the blood pressure. If he has another type of Dementia then any treatment offered would be a plus but as you say not a cure. If he refuses to go his previous history of stroke would indicate (though not guarantee) he has Vascular Dementia, which means very little would have been lost.
I only replied to you to attempt to answer your question and try and give you some reassurance if your husband refuses to go. Dementia throws up a number of potentially no win situations. Carers have to try and do their best with what is available at any moment in time. I close in wishing you well for the future.
