Memory appointments are short, and a great deal depends on what you bring to them.
A doctor seeing someone for fifteen minutes cannot observe a year of gradual change. You can describe it, and that description is often the most useful thing in the room.
a first appointment is mostly history taking.
Expect questions about what has changed and when, a short cognitive screening test, blood tests to look for treatable causes such as thyroid problems or vitamin B12 deficiency, and possibly a referral for imaging or to a specialist.
You are unlikely to leave with a diagnosis, and that is normal. Working out what is causing memory change takes more than one visit.
if you are going with someone, agree beforehand how you will handle it.
Being talked about in the third person while sitting in the room is one of the most common complaints people with memory problems have. Let them answer first. Add what they have missed afterwards, or ask for a moment with the doctor separately if there is something you cannot say in front of them.
