Recent studies have shown that drugs with psychedelic effects, such as psilocybin, LSD, MDMA, and cannabis, may have a positive impact on aging adults. A survey conducted on 3,294 US adults aged between 42 and 92 found that those who had used hallucinogens in the past year reported fewer depressive symptoms and showed improvements in higher-order brain functions. This has sparked interest among researchers in exploring the potential benefits of psychedelics for older adults.

Compared to non-users, individuals who had used psychedelics scored higher on tests measuring inductive reasoning, verbal fluency, working memory, processing speed, attention switching, and inhibitory control. However, there was no significant difference in episodic memory between the two groups. While these findings are promising, it is essential to note that the study was observational and cannot establish a cause-and-effect relationship.

In recent years, psychedelics have gained scientific interest due to their therapeutic potential in treating neuropsychiatric disorders like anxiety, depression, and post-traumatic stress. Clinical trials have shown promising results with drugs such as psilocybin, LSD, ketamine, and MDMA. Despite this, research on the use of psychedelics in older adults is scarce, highlighting a significant gap in the literature.

Researchers Kallol Kumar Bhattacharyya and Kaeleigh Fearn argue that psychedelics could be a valuable tool in enhancing cognitive functions in older adults. Studies have suggested that psychedelics can improve creativity, executive function, and mood in aging individuals. However, more longitudinal research is needed to explore the full potential of psychedelics in late-life cognitive functions.

While the idea of psychedelic-assisted therapies for older adults holds promise, rigorous long-term trials are necessary to determine the safety and efficacy of this approach. Some hallucinogens can have adverse effects on the cardiovascular system and induce ‘bad trips’, especially in individuals with personality disorders. Therefore, caution must be exercised when considering the use of psychedelics in older populations.

Further research on psychedelics could provide valuable insights into the aging brain and potential therapeutic interventions. While psychedelics may not directly address age-related cognitive decline, they could potentially enhance overall well-being and mood in older adults. Controlled and monitored use of psychedelics in therapy settings may open new possibilities for improving the quality of life for aging individuals.

While the use of psychedelics in aging adults is still a relatively unexplored area, preliminary findings suggest that these substances may have potential benefits for cognitive function and emotional well-being. Continued research and clinical trials are essential to fully understand the impact of psychedelics on aging populations and to unlock their therapeutic potential in late-life cognitive functions.
