A recent study suggests that aromatherapy could potentially aid in the recovery from depression by enhancing the recollection of specific, often positive, memories. Published on February 13 in the journal JAMA Network Open, researchers found that scents were more effective than words in triggering memories of particular events, which could potentially help individuals break free from negative thought patterns associated with depression.
Senior researcher Kymberly Young, an associate professor of psychiatry at the University of Pittsburgh School of Medicine, explained that enhancing memory could lead to improvements in problem-solving, emotion regulation, and other functional difficulties commonly experienced by those with depression.
In the study, 32 adults diagnosed with major depressive disorder were asked to recall a specific memory while inhaling various potent scents from glass vials. These scents ranged from oranges to ground coffee to the distinctive aroma of Vicks VapoRub. Previous research has shown that individuals with major depression often struggle to recall specific memories from their lives, which may contribute to the perpetuation of negative thought patterns.
Young, a neuroscience researcher, theorized that targeting the amygdala, a brain region involved in memory and emotion processing, could help disrupt this cycle. The amygdala is known to be engaged by odors, resulting in vivid and realistic memory recall.
The study revealed that participants with depression who received odor cues were better able to recall specific events, such as visiting a coffee shop on a particular Friday, compared to those who received word cues. Additionally, memories triggered by scents were reported to be more vivid, immersive, and real. Interestingly, participants were more likely to recall positive events, even without specific instructions to do so.
The researchers plan to further investigate the mechanisms underlying these findings, particularly focusing on whether scents engage the amygdala more effectively than word cues using brain imaging techniques. These findings highlight the potential of aromatherapy as a novel approach to improving memory recall and potentially alleviating symptoms of depression.
