Society has a deep-set bias against the mind as an entity, for obvious reasons such its intangibility & its dependence on non-stop dynamic action. 

Language distorts how we see things.  Body & brain are solid, concrete organs easily conceived of but the mind doesn't seem real to us, being an intangible entity based on pure process & zero state, totally insubstantive, impossible to define. Unable to come to grips with either the normal or the disturbed mind, we find it difficult to validate mind-based or mind-sensitive illnesses or give them the same respect as physical illnesses of the body. So we say things such as "it's all in your head" to women & disrespect both stress-sensitive symptoms & those of an intrinsically emotional nature.
