TYPICAL SIGNS AND SYMPTOMS IN PSYCHOPATHOLOGY
SIGNS AND SYMPTOMS
The major differences between signs and symptoms are described on the table below:
SIGNS
SYMPTOMS
 Objective
 Subjective
 Based from clinician’s observation
 Subjective experiences of the patient
However, psychopathological signs and symptoms are not clearly differentiated, they often
overlap. A syndrome, or a constellation of signs and symptoms that make up a recognizable condition, is
often used to show the overlap of the two.
TYPICAL SIGNS AND SYMPTOMS IN PSYCHOPATHOLOGY
