ABSTRACT
Psychosis is the most serious type of mental disease: madness, in lay terms. Characteristic of psychosis is more or less intermittent loss of contact with reality, which is replaced by the thoughts and imaginings of the patient’s own disturbed mind. The psychoses comprise those in which the brain is structurally intact but its working impaired-the functional type, and those in which there is a physical fault or lesionthe organic type.
