Is it better to seek formal diagnosis or not?

[tedlassoforprimeminister]

It’s clear my relative is struggling. Lots of conversations in the family about cognitive function.
there is some fear about seeking a diagnosis. Some of it is around the relative not really acknowledging their difficulty, and if they are taken to the dr they will be resistant.
the other part if it is the fear that if dementia is diagnosed, the decline will be faster.
can anyone help with pros and cons of avoiding a diagnosis vs seeking one.
relative currently living with spouse.
thanks.

As someone who has worked with dementia I feel I can give input:

positives: diagnosing the specific form of dementia can help understand what the individual may be experiencing, as well as what you may be able to expect in the future (some have faster decline, some more stable, some may severely effect mobility faster etc)

sometimes there may be medication to help (some don’t believe it helps)

It’s easier to get a diagnosis at the start than it is a few years down the line

protection for finances - appointing LPA can help prevent financial abuse.

Negatives - denial

I have no medical training and even after my mum's diagnosis, nothing has changed medically in that we aren't giving her any meds ( other health issues complicate it).

But speaking for myself, and probably my brother, it is helpful to know when a relative has dementia. You then know there is little point in trying to reason with your parent. It takes some of the pressure off. You have an explanation for lots of odd things. My mum's diet has completely changed, her sleep routines are all over the place. In a way it brings other things to consider but you understand the illogical comments and behaviours and you can give yourself permission to back off, and just go with the flow. When my mum acts strangely to her grandchildren, they now know what's going on. There's a reason behind it. It's a small consolation but it does have some value.

On a practical note, it can also make accessing support easier, such as Attendance Allowance, Blue Badge etc.
