I understand how you feel about waning abilities, but have difficulty imaging how it must feel when you are young with so many responsibilities. I'm 78 and have been noticing small changes for the last 8 years, and was finally diagnosed 2 months ago.
Having my suspicions I have been researching Alzheimer's disease for a few years now.
Popular belief among physicians seems to be that Alzheimer's is caused by Amyloid-beta protein plaques which form in the brain and destroy brain cells (though this has recently been shaded by suspicions that a significant research paper had dubious authenticity). These plaques are not easily revealed by a conventional MRI, so diagnosis of dementia is made by a standard series of tests (which you seem to have been through) and the results of different tests is used to determine which (if any) dementia you have, I have been diagnosed with mixed dementia (mainly Alzheimer's, with a bit of vascular).
Another sort of brain scan (PET CT) with a slightly radioactive intravenous drip beforehand, is much more effective at detecting the plaques (in my case 12 months before my NHS diagnosis was confirmed).
If you go to the home page (above) and then select Alzheimer's Society, you will find plenty of useful information and many 'factsheets' and other publications, which I have found useful.
