While having a close relative, such as a parent or sibling, who has depression does not automatically mean that an individual will develop it themselves, studies have shown that having a close relative who has depression causes an individual to be more 1.5 to 3 times more likely to develop it (“Genetic Causes of Depression”, 2013). This study illustrates that genetics possibly have a key role in the development of depression in those who have a close relative who have it. Furthermore, neural activity in the brain can also create depression in people. It has been shown that the adaptive mood regulating brain circuitry, or the neural activity associated with the prefrontal cortex, differs for those who have depression and those who do not have depression (Johnstone, Van-Reekum, Urry, Kalin, & Davidson, 2007). For non-depressed individuals, the neural activity in the prefrontal cortex for adaptive mood regulators is left-lateralized in activation, whereas for individuals who have depression have a bilateral activation (Johnstone, et al., 2007). Clearly, both genetics and neural activity are involved in the development of depression, and thus biological forces are a key component in …show more content…
One such aspect of these forces in action is when someone lives in poverty, or when they live in a culture in which impoverished conditions exist. There are multiple factors that could cause depression when someone lives in poverty, such as lack of adequate shelter, medical necessities, or even food, all of which are basic for human survival (Belle & Doucet, 2003). When these needs are not met, many people feel a sense of hopelessness and despair, which are symptoms of depression. (Belle & Doucet, 2003). It is also worth noting that when parents cannot provide for their young they likely feel pangs of sadness, believing that they are failing their children, which adds to depression itself (Brown & Moran, 1997). In addition to living in a culture in which someone must face poverty for themselves, culture also dictates how depression is handled. For example, in American culture, men are not supposed to be overly emotional beings, and instead they are expected to be strong leaders who hide their emotional expression. This could hinder a person’s maintenance of depression as this person could feel shame simply thinking of going to someone else for help with their depressive feelings (Lawal-Solarin, 2010). In other cultures, such as the African-American culture who are much more collectivistic and family-oriented, these
