Over-diagnosis: ageing and memory changes

Primum-no3Submission to BMJ rapid-responses, 14 September 2013 by Dr Peter J. Gordon

I congratulate the authors (1) for presenting what has for far too long been missing in “consensus” discussions on cognitive changes as we get older.

It does not follow that a diagnosis is always to be viewed as a “curse” (as used in a sub-heading by the authors) but I certainly do agree that over-diagnosis and mis-diagnosis have the potential to be. This may especially be the case in our elders who may be frightened to complain or ask questions of medical authority (2).

Language used in this area, indeed in all areas of medicine, is important. Surely it is time to stop using military metaphors (war, fight, targets etc); metaphors around epidemics (burden, killer); and metaphors based on maps (pathways, signposts etc). This is also my concern with the word “curse”.

In this week’s online BMJ are three excellent blog posts by William Cayley (3), Leana Wen (4), and Edward Davies (5). They substantially add further to this important evidence-based analysis on memory loss in age by Professor Le Couteur.
