Hello Tracey Ann
first thing is not to prejudge anything at all!
Many conditions can cause some symptoms that make us fear we may have all sorts of things. Stress and overwork, depression, burn-out, can all give us worries because these can manifest with some symptoms that may appear like dementia.
Caring for four young children is such a major thing that it may simply be draining you.
If you are having tests, then please try not to worry more than necessary, and await the results.
Can you tell us what were the things that led you to having the tests organised? What happened?
Very best wishes
