Welcome from me too
@Halcyon.
Many of us have been in similar situations, waiting for results and unsure what comes after.
Take advantage of any opportunity to ask questions following diagnosis, if diagnosis it is. Make a note so you don't forget anything.
Fingers crossed for you it goes as well as it can.
Once you know where you stand, take @Izzy`s advice and start your own thread in I have a partner with dementia where I know you will get the best support possible.
