Genetic implications for major affective disorders.

This article reviews the current outcomes of twin, adoption, and family epidemiological studies. Psychiatric genetics research has made a major paradigm shift from epidemiology studies to molecular genetic research. The manner in which affective disorders are inherited continues to elude scientists. Nurses, in collaboration with patients, families and scientists, can facilitate the research process. Merging our professional caring with the biological research outcomes will assure our professional contribution in this expanding research and assist the affected persons from further stigmatization.
