Liquor analysis result: dementia possible.

[LineVec]

I have a question regarding a lab result of my elderly father. The neurologist is busy at the moment so we/I couldn’t speak directly to her. If it says, that possible does it maybe mean that it is in a grey zone or just a euphemism for not scaring the patient/relatives? I can say to my father he is still quite active person, also still works as an architect despite his high age and yeah has issues with forgetfulness but on the other hand has still a sharp mind.
