I think that it depends on your area, our Memory Clinic was accessed quickly, they talked about a scan but I think it was so clear that they didn’t bother and diagnosed Alzheimer’s. The tablets that help slow the symptoms onset didn’t work for us - first one removed appetite - virtually completely and the second gave non-convulsive seizures. That said the medication isn’t a cure and for us would have limited benefit. But, with having the diagnosis, we got into a system - officially I’m a carer so got a respite card of £1200 a year. about £100 a year for me for a hobby, attendance allowance, carers allowance, discount on council tax, GP register me as a carer so they talk to me. None if it changes the difficulty of each day but it all helps. Some of the payments cover the day centre my OH goes to.
After the initial diagnosis, I have never reminded him of it, I go to appointments and go in first so that he doesn’t have to hear what needs to be said. One of the additional elements if these conditions is the complete lack of dignity given to them - we are there because he doesn’t remember but they ask questions - do you get aggressive, no, not me when he does so I have to say it in front of him - I just refuse to do it now. A bit long but hopefully some of these things will help you going forward. Good luck.
