The recent survey conducted on a group of US adults aged between 42 and 92 suggests that the use of psychedelic drugs may have beneficial effects on brain health as individuals age. Those who reported using hallucinogens in the past year displayed fewer depressive symptoms and showed improvements in higher-order brain functions. This includes enhanced inductive reasoning, verbal fluency, working memory, processing speed, attention switching, and inhibitory control. However, it is important to note that these individuals did not perform better in episodic memory tests, which is responsible for storing everyday events and is often impacted by dementia.
One of the limitations of the study is that the findings are purely observational and cannot establish a cause-and-effect relationship. Additionally, the research relies on subjective accounts of psychedelic use and does not differentiate between the types of psychedelics consumed. This lack of control over drug dosages and subjective reporting may introduce bias into the results, making it difficult to draw definitive conclusions about the effects of these substances on brain health.
Despite the limitations of the study, gerontologists Kallol Kumar Bhattacharyya and Kaeleigh Fearn believe that there is merit in further exploring the potential therapeutic benefits of psychedelics for older adults. Recent clinical trials have highlighted the therapeutic potential of substances like psilocybin, LSD, ketamine, and MDMA in treating neuropsychiatric disorders such as anxiety, depression, and post-traumatic stress. These drugs have shown promising results in mitigating the symptoms of these conditions and improving overall mental health.
What sets this study apart is its focus on older adults, a demographic that is often excluded from psychedelic research. Given that older age is associated with declines in executive function and mood disorders, exploring the impact of psychedelics on cognitive function in this population is crucial. Some studies have already suggested that psychedelics can enhance creativity, improve executive brain function, and potentially slow down cognitive decline even at small doses.
Bhattacharyya and Fearn advocate for the decriminalization of psychedelics to facilitate more robust research that ensures reliability and validity. They emphasize the need for longitudinal studies involving both clinical and community samples to fully understand the potential benefits of psychedelics in enhancing cognitive function in late-life. While there are concerns about the safety and efficacy of psychedelic-assisted therapies, rigorous, long-term trials are necessary to evaluate their effectiveness as clinical tools for older adults.
Psychedelics like psilocybin, LSD, and MDMA have been shown to stimulate new connections between neurons and potentially repair broken connections in the brain. Initial clinical trials have demonstrated their effectiveness in treating depression, stress, and anxiety disorders, conditions that are often associated with cognitive impairment. The ability of these substances to alleviate emotional stress may contribute to improved overall brain function, particularly in older individuals facing cognitive decline.
While the use of psychedelics in aging brains is still a relatively unexplored area of research, there is growing evidence to suggest that these substances may have positive effects on cognitive function and mental health. Further studies are needed to fully understand the mechanisms underlying these benefits and to ensure the safety and efficacy of psychedelic-assisted therapies for older adults. By decriminalizing psychedelics and conducting more longitudinal research, we may uncover valuable insights into how these substances can be used as alternative therapies to support cognitive function in late-life.
