Over time the diagnosis of schizophrenia has changed, but is a strict categorisation of the condition really necessary?
I have the greatest respect for GPs. Everyone who crosses the threshold of my consulting room has first been assessed by someone else; however, GPs have to take on whoever turns up. Not only that, but the number of diseases described grows, and the measures for both diagnosing and managing them grow exponentially. The same exponential growth is happening in the specialist fields of medicine; one cannot expect generalists to keep up with it all when specialists are battling as well.
