There are so many medical conditions that can superficially manifest themselves as psychiatric conditions. Isn't it about time that psychiatry treat not just the symptoms but become well versed in figuring out the possible physical reasons?
We know some of the causes of psychiatric disorders but science is not yet "there" to tell us everything.
All psychiatric disorders have a biological basis but not all psychiatric symptoms are the result of other medical disorders. Part of the challenge for physicians is to figure out if a patient has only a psychiatric disorder or a psychiatric and another medical disorder.
