Description
In 2017, suicide was found to be the second leading cause of death for people aged 10 - 34 in the United States. At least 90% of suicides are found to be comorbid with mental illness, most commonly: depression. Research suggests depression develops due to a combination of environmental, psychological, and biological factors. Imbalances in neurotransmitters, specifically serotonin (5-HT), is one of the leading hypotheses for the biochemical basis of depression. On this basis, selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressant and have been shown to be an effective treatment for moderate to severe depression. However, in 2004, the FDA mandated that SSRIs be given a ?black-box? label warning indicating the relationship between the medication and increased risk for suicidal ideation and behaviors. This literature review seeks to investigate the available research on the mechanisms of SSRIs in the treatment of depression, and their highly contested relationship with suicide risk. I aim to make sense of this data and determine where the evidence points in regard to the costs and benefits of prescribing SSRIs, as well as the kind of future investigation needed to fully understand these drugs.
