During my work as a consultant pharmacist, I saw quite a few patients who were
hospitalized for psychosis later to be found to be suffering from hyperthyroidism and a patient who was found to have under - treated hypothyroidism after being hospitalized for treatment - resistant depression.
But when physicians interviewed patients
hospitalized after their initial psychotic episode, they were startled to learn that in many cases, «people began experiencing changes in cognition, behavior, and perception
for months or years» before
psychosis struck, Heinssen says.
