Heredity & Genetics

It has long been noted that bipolar disorder (manic depression) runs in families. Scientists continue to work toward discovering the genetics underpinning of this fact. These resources look at this research.
Gene Hunting
Research has shown that vulnerability to mental illness comes from the joint effects of many genes acting together with non-genetic factors.
Bipolar Disorder and Heredity
In this article by Tanja M. Meece, she writes “It has long been believed by lay and medical people that bipolar disorder is hereditary. Geneticists laboring under the same belief are endeavoring to determine which genes and chromosomes, in tandem or singularly, are the carriers of bipolar disorder.”
The Darwinian Challenge
John McManamy examines depression and bipolar disorder in the light of evolutionary biology and Darwinian medicine, to see why these illnesses survived natural selection.
The Family Psychoeducational Approach
This article by Demitri F. Papalos discusses the heredity issue and the "generational impact of mood disorders.”
Genetics Holds Clues to Mental Disorders
An article by By Tom Siegfried and Sue Goetinck addressing the argument of nature vs. nuture. “As with many diseases, mental illness can run in families, suggesting that genetics plays a role. But genes don't tell the whole story.”
Link Found Between Serotonin Transporter Gene And BPAD
Bipolar affective disorder is a complex genetic disorder -- this means there are likely to be a number of different genes involved in each person affected, as well as causes related to personal experiences such as significant life events. However in some families, bipolar affective disorder might be caused by a single gene.
Multiple Gene Sites
Evidence is mounting that manic depressive illness stems from multiple genes.
Inherited Depression Linked To Shortage Of Cells
People who suffer from depression have fewer cells in a certain part of the brain, a new study finds. This loss occurs only when the disorder runs in the family, suggesting that inherited depression may differ from depression that comes out of the blue.
