Impact of Poverty on the Brain by Paulina Gonzalez



Poverty, how often does one encounter its obvious impacts in society? One would quickly say quite often. It is everywhere and the impacts of poverty are noticeable. The human eye captures the impacts on appearance, standards of living and a few visible aspects of health, such as obvious malnutrition. Yet, what about those impacts the eye cannot see? This question only leads to more questions. Poverty also has an extensive impact on the brain and its functioning. Children that suffer from poverty are at a higher risk for further problems in life. This can lead to a struggling adulthood as well. Impoverished children can suffer from depression, anxiety, lower brain functioning, and other disorders, such as post-traumatic stress disorder. All of these being very negative effects of poverty on the brain. These children grow up to be troubled adults, not all, but a good amount to create a viscous cycle. It is highly important to also mention that poverty doesn't only exist in the city, it is everywhere, like in rural areas and even more in Native American reservations. Here, one will find out about the impacts of poverty on the brain in depth, what areas of the country are more highly affected, and other rising problems.
Moreover, in order to understand the impact of poverty it is beneficial to know numbers of poverty rates and impacts throughout the country. Cities across the nation have experienced poverty at many different levels. There is no doubt that there are areas that experience poverty at higher levels. Between the years of 2009 to 2011 American households shared that they had suffered from poverty for at least three months or more. (U.S. Census Bureau, 2013) At least 31.6 percent of households represent these families. Although, the Census states that severe poverty was "uncommon" being at less than 3.5 percent between the years of 2009 and 2011, it is important to keep in mind that not everyone participates in census reporting. Also, it would be difficult to measure those families that are stricken by poverty that are homeless or constantly moving in and out of households. Another thing to notice is that child poverty levels have increased up to 19.9 percent in 2012 dating back since 1999. (U.S. Census Bureau, 2013) Detroit, Michigan, is one of the areas that has higher poverty levels, experiencing it as a 42.3 percent. Other cities in Michigan also have high rates of poverty, such as Flint and Lansing, at 38.9 and 36.1 percent respectively. Yet, poverty is not just common in the northern areas of the country. For example, Athens, Georgia, and Brownsville, Texas, also experience poverty at high rates. (Bloomberg, 2014) Poverty had spread all throughout the country in the recent years. One should not forget the areas one cannot see. Native American reservations actually suffer from poverty at very high rates. An example of this is the Navajo Nation that has a population approximately of 180,462 , and of that total 43 percent live below the poverty lines. (Navajo Nation Business, 2014) From rural to urban areas poverty strikes the most vulnerable communities.
Furthermore, the rising problems of poverty are demonstrated in the everyday lives of those who are caught up in its wrath. The focus should begin at the youngest sufferers, children. Often children are the ones that are impacted by poverty at higher levels. Poverty begins at home. There have been many studies that have recently created a link between poverty and impacts on the brain. First, children at risk in poverty stricken homes lead more troublesome lives. Poverty impacts children in many forms. Visible impacts are that in education, quality of living, and nutrition. Pregnant women that suffer from poverty at are a higher risk to suffer from stress, malnutrition, and other disorders. This of course also has an impact on the unborn child. Even at a very early stage of their lives children are already experiencing the effects of poverty on their health. In recent studies about the impact of poverty on the brain researchers have found that poverty stricken children have lower volumes of white and gray matter in the brain. What does this mean one may ask. Well, according to the studies, white and cortical gray matter are important nerve tissues that help regulate sensory perception, speech, memory, emotions, and brain communication. Another finding of these studies is that poverty also impacts other areas of the brain. These areas are in the hippocampus and amygdala. The volumes of these two areas also seem to be a lot lower in impoverished children. The researchers at JAMA pediatrics state that the hippocampal volumes represent the caregiving that the children are exposed to. The present link is that those children in poverty had lower hippocampal volumes due to lower levels of significant caregiving from parents or guardians. (JAMA pediatrics, 2013) The hippocampus is important for short and long term memory. The amygdala was also impacted by poverty according to this study. The amygdala is an area of the brain that functions are emotions and memories. Impairment in these areas, according to JAMA pediatrics, suggests that children can have lower concentration levels, aggression, stress and traumatic life events. Yet, as the children grow so does poverty alongside.
As one continues, it is easier to realize that poverty effect people at a young age. All things grow as do children. Even though not all impoverished children become impoverished adults, the numbers are statistically high and success stories are smaller. As stated before, studies have established a new connection between poverty and impacts on the brain in children. Yet, what happens to the poverty stricken brain as it continues to grow? There are many answers to this question. On a social level poverty strikes in many ways, such as poor quality of living/shelter which can lead to other rising problems. Emotional distress, stress, anxiety, and other disorders can become an apparent outcome of poverty not only as a child but also as an adult. Although there is not a direct link between poverty and drug abuse, research have shown that drug abuse is more prevalent in impoverished communities. This leads to another impact of poverty on the brain. Drug abuse can have an number of impacts on the brain. Stress and anxiety are also another impact of poverty. Going back to the research on children, another finding was that those parents with stress caused by poverty showed more negative caregiving mechanism. This also had an impact on the amygdala, hippocampus and the regulation of emotions. Thus, suggesting that stress and anxiety induced by poverty in parents was also transmitted to children through the forms of support versus hostility. Therefore, the children growing in poverty tend to have more problems managing stress and other emotions as adults. This takes one back to the drug abuse because impacts in these areas of the brain can also lead to risky behaviors. This does not mean that poverty leads to drug abuse but it does create a possible link between the two. Then, this shows that drug abuse also has high impacts on the brain such as mental illness, emotional distress and unstable relationship that can prolong drug abuse and or other forms of abuse. Another thing that poverty impacts is the use of alcohol. An example of this is going back to the Navajo nation, Alcoholism is at its highest rate in Native American reservations. Statistics show that alcoholism affects this population about at a 514 percent higher than the rest of the country. (Rex Lee Jim, 2012) This leads one to become aware of the impact of alcoholism on the brain. According to the National Institute of Alcohol Abuse and Alcoholism, alcohol can have highly negative impact on the brain. It can cause brain damage, nerve damage, black outs, memory loss, and other sense impairments. This is important to know because in these reservation unemployment rates are very high which often lead to depression. One can easily notice where the cycle is going. Also, in most reservations alcohol is actually banned, it is important to understand how poverty may lead to risky behaviors that might create negative impacts on the brain. All of these taken by impoverished adults also impact the lives of their children, and the children grow up to have struggles in such poverty stricken communities. Thus, creating a cycle that is difficult to end.
Overall, poverty has many impacts in the lives of those that face its struggle. As mentioned before poverty strikes at birth. Poverty stricken children have high risk for emotional stress, anxiety, and risky behaviors such as drug abuse. Some effects of poverty are very visible to the eye. Yet, there are many impacts of poverty that cannot be readily seen at first glance. An example of this is the impact that poverty has on the brain. As research shows, poverty may actually impact the brain on a few different levels and areas. Impacts to the brain at a young age can lower its functioning and may lead to other rising problems such as lack of ability to regulate emotions. As final thought, researchers have suggested that one form to lower the impacts of poverty on the brain is to create and form supportive caregiving mechanisms between the children and their parents/guardians. The idea behind this is to help lower stress for children and allow the brain to fully grow to its capacity in every aspect. (JAMA pediatrics, 2013)
