Genes and Stress

A recent study by Jacob Crouse and Ian Hickie from the University of Sydney is reevaluating the classifications of depression into reactive and endogenous types. Historically, reactive depression was seen as a response to external stressors, while endogenous depression was thought to stem from internal factors like genetics. However, their research involving over 14,000 individuals in the Australian Genetics of Depression Study shows a more complex interplay. They discovered that people with higher genetic risks for mental disorders reported more exposure to stressful life events, suggesting that genetic predispositions can influence both one's environment and one's reactions to it. This challenges the simple categorization of depression and underscores the intricate relationship between genes and environmental stressors.
