In the modern world many women now have very successful careers in extremely demanding fields.  A huge impact of menopause is not addressed by these studies, Brain Fog.  It seems to receive little attention yet impacts job performance significantly.  Sometimes to the extent of a person finding themselves driving through the city with no idea of why or where they are going ! - Actual event described by friend Psychologist (PhD).  I also have found myself in the same situation during business meeting... not fun !  Glad to see all the horrible side-effects being taken seriously, but this one too should be on the radar.  Thank God for HT at least.  Not a very scientific comment I am afraid, but many women will relate.
