Definitions and Examples

Case Study: Case study is a research methodology, typically seen in social and life sciences. There is no one definition of case study research. However, very simply… ‘a case study can be defined as an intensive study about a person, a group of people or a unit, which is aimed to generalize over several units’. A case study has also been described as an intensive, systematic investigation of a single individual, group, community or some other unit in which the researcher examines in-depth data relating to several variables.

Clinical Symptoms: A symptom is a manifestation of disease apparent to the patient himself, while a sign is a manifestation of disease that the health provider perceives. The sign is objective evidence of disease; a symptom, subjective. Symptoms represent the complaints of the patient.
