The United States has a long history of racial injustice, one of the most visible examples is the disproportionate number of Black individuals in prisons. This issue became more pronounced after the Violent Crime Control and Law Enforcement Act of 1994. This law led to a significant increase in the number of people behind bars. The law also led to a large number of people racialized as Black being locked up.

     This situation has far-reaching effects, especially on the mental well-being of Black elders. Living in areas with high rates of incarceration can be incredibly stressful. This stress can take a toll on a person's cognitive abilities, which are the skills needed to think, learn, and remember. This is a big deal because cognitive health is crucial for living a good life, especially as one gets older.

     Researchers looked into this issue by studying data from the Health and Retirement Study. They focused on Black adults over 50 who lived in counties with high rates of incarceration between 1995 and 2005. They found that in counties where more Black individuals were incarcerated, the cognitive test scores of Black elders were lower. This suggests that the stress and trauma of living in an area with high incarceration rates can negatively impact brain health.

     It's important to note that this stress doesn't just affect the individuals who are incarcerated. It also affects their families, friends, and entire communities. This is what is often referred to as structural racism. It's a system that puts certain groups at a disadvantage, in this case, leading to more Black individuals being locked up and their communities suffering as a result.

     The researchers used a 27-item test to measure cognitive performance. This test was administered in-person or online. The results showed that for every 1, 000 more Black individuals incarcerated per 1, 000 population, the cognitive test scores of Black elders decreased. This is a clear indication that the stress of living in an area with high incarceration rates can have a real and measurable impact on brain health.

     The findings of this study are a stark reminder of the long-term effects of racial injustice. They highlight the need for policies that address the root causes of incarceration and support the communities most affected by it. It's not just about the individuals behind bars, but also about the families and communities left behind.
