Man is a social animal and lives in highly
complex societies. Societies are specially meant to make life easier, smoother
and more comfortable. A society also offers competition, stress and strain.
Such social factors, if prolonged, may cause mental tension and mental illness
(like depression, anxiety, etc.) in some persons, which may create various
behavioral changes in them. These changes may be disturbing for himself and his
society too. Thus, any abnormal change that causes distress and discomfort to
the lives of both the concerned person & the people around him may be
termed as socially significant disease.
