Abstract
The author describes the changing aspects of schizophrenia. It seems that the paranoid and atypical forms are more frequent while catatonia is decreasing in frequency. As a consequence, the prognosis seems to be better and the treatment has had to evolve. The author feels that the greater knowledge of the psychology of the ego that psychiatrists have and the better understanding that is imparted to the family members, plus the physiological effects of the new drugs are responsible for this better prognosis.
