A groundbreaking study published in JAMA Network Open sheds light on the potential impact of cannabis use on brain function, particularly in the realm of working memory. This extensive research, involving over 1,000 young adults between the ages of 22 and 36, utilized advanced brain imaging technology to assess cognitive performance across various tasks.
The findings revealed a significant correlation between heavy cannabis use and reduced brain activity during working memory tasks. Researchers defined “heavy users” as individuals who had consumed cannabis more than 1,000 times in their lifetime. Notably,63% of these individuals exhibited diminished brain activity compared to non-users.
“As cannabis use continues to grow globally, studying its effects on human health has become increasingly important,” stated dr. Joshua Gowin, the study’s lead author and assistant professor of radiology at the University of Colorado School of Medicine.”By gaining a comprehensive understanding of both the benefits and risks associated wiht cannabis, we can empower individuals to make informed decisions and fully comprehend the potential consequences.”
Working memory, the cognitive ability to hold and manipulate details temporarily, plays a crucial role in everyday tasks such as following instructions, solving problems, and making decisions. The study suggests that heavy cannabis use could impair this essential function.
dr. Gowin emphasized the meticulous nature of the research, stating, “We applied the highest standards to our research, setting rigorous thresholds for statistical significance across all seven cognitive function tests. To minimize the risk of false positives, we employed false discovery rate (FDR) correction. While some of the other tasks indicated potential cognitive impairment, only the working memory task showed a statistically significant impact.”
The researchers observed that heavy cannabis use appeared to reduce brain activity in specific regions responsible for working memory, including the dorsolateral prefrontal cortex, dorsomedial prefrontal cortex, and anterior insula. These areas are critical for decision-making, memory consolidation, and attentional control.
While this study highlights the potential cognitive consequences of heavy cannabis use, further research is needed to fully understand the long-term effects and individual variability in response to cannabis.
The human brain, a remarkably complex organ, is constantly being studied and understood. Recent research at the University of Colorado Anschutz Medical Campus is delving into the intricate relationship between cannabis use and cognitive function, particularly memory.Dr. Joshua Gowin, an assistant professor of radiology, is leading this groundbreaking study, examining how cannabis affects the brain during memory tasks.
The study, utilizing advanced brain imaging techniques, finds that cannabis use can influence brain activity patterns during memory work. Dr.Gowin explains, “People need to be aware of their relationship with cannabis since abstaining cold turkey could disrupt their cognition as well. For example, heavy users may need to be more cautious,”
Gowin emphasizes the need for further inquiry, stating, ”There are a lot of questions we still need answers to regarding how cannabis impacts the brain. Large, long-term studies are needed next to understand whether cannabis use directly changes brain function, how long these effects last, and the impact on different age groups.”
The University of Colorado Anschutz Medical Campus is a leading center for research and innovation in the field of medicine. Driven by a commitment to improving patient care and transforming lives, the campus houses world-renowned experts, cutting-edge facilities, and a collaborative environment. In addition to its research endeavors, the Anschutz Medical Campus is home to two highly-regarded hospitals: UCHealth University of Colorado Hospital and Children’s Hospital Colorado. These hospitals provide remarkable patient care to a diverse population, exceeding two million adult and pediatric visits annually.
