Therapy (Latin therapīa; Greek: θεραπεία) literally means “curing, healing” and is the attempted remediation of a health problem, usually following a diagnosis. In the medical field, it is synonymous with the word “treatment”. Among psychologists, the term may refer specifically to psychotherapy or “talk therapy”. Preventive therapy or prophylactic therapy is a treatment that is intended to prevent a medical condition from occurring. For example, many vaccines prevent infectious diseases.
