- 0:00Welcome to Morning Medical with Dr.
- 0:01Chow.
- 0:02I'm Dr.
- 0:02Chi-Ming Chow, and today we're diving into a fascinating study that's raising some eyebrows
- 0:07in the medical community.
- 0:09We're talking about the potential link between cannabis use and dementia, a topic that's
- 0:13gaining attention as cannabis becomes more widely used and accepted in various parts of
- 0:18the world.
- 0:22A Canadian study, published in JAMA Neurology, has shed light on a concerning association
- 0:28between emergency care for cannabis use and an increased risk of dementia.
- 0:34This analysis was conducted on a massive scale, involving over six million people in Ontario,
- 0:40Canada, who were 45 years and older and had no history of dementia when they joined the cohort
- 0:46between 2008 and 2021.
- 0:50The study found that individuals who required emergency department visits or hospitalizations
- 0:54due to cannabis use had a 23 percent higher risk of developing dementia within five years
- 1:00compared to those who had acute care for other reasons.
- 1:04Even more striking, the risk of being diagnosed with a new case of dementia was 72 percent
- 1:10higher than the general population within that same timeframe.
- 1:15To put it in perspective, among those who needed acute care due to cannabis use, the
- 1:21absolute risk of developing dementia was 5 percent, compared to 3.6 percent for those with
- 1:28all-cause acute care.
- 1:31This risk was even more pronounced when compared to the general population, where the
- 1:35absolute risk stood at 1.3 percent.
- 1:39The researchers, led by Dr.
- 1:41Daniel Myran from the University of Ottawa, adjusted for various factors such as
- 1:46sociodemographic variables and chronic health conditions.
- 1:51Despite these adjustments, the heightened risk remained significant, highlighting a potential
- 1:56link that warrants further investigation.
- 2:00Interestingly, the study also noted that the risk of dementia associated with cannabis use
- 2:05was lower than that linked to alcohol use, yet it still poses significant concerns.
- 2:11Dr.
- 2:11Colleen Webber, a co-author of the study, pointed out that regular cannabis use might
- 2:16lead to changes in brain structure or increase the risk of other dementia-related factors like
- 2:23high blood pressure, head trauma, and social isolation.
- 2:27It's important to note, however, that the study does not claim cannabis use directly causes
- 2:33dementia.
- 2:34There are limitations, as the study did not examine patterns of cannabis use that did not
- 2:39result in acute medical care, and factors like residual confounding and reverse causation
- 2:43might have influenced the results.
- 2:46Despite these limitations, this study is significant because it represents the largest
- 2:51analysis to date on the association between cannabis-related emergency care and dementia.
- 2:58With the liberalization and legalization of cannabis in Canada, particularly since 2014,
- 3:05these findings highlight the need for further research into the long-term effects of cannabis
- 3:09use.
- 3:12NDP Leader Jagmeet Singh has made a significant pledge in the run-up to the Canadian federal
- 3:17election, promising to hire thirty-five thousand nurses by the year two thousand
- 3:22thirty.
- 3:23This announcement comes amidst growing concerns about the state of Canada’s healthcare system,
- 3:28which has been under pressure due to underfunding and staffing shortages.
- 3:33During a recent election event in Toronto, Singh outlined his commitment to not only
- 3:38increase the number of nurses but also to ensure safe working conditions for them.
- 3:43He emphasized the importance of maintaining an appropriate ratio between nurses and patients,
- 3:49although he did not specify what that ratio should be.
- 3:52Instead, he mentioned that an NDP government would collaborate with provincial and
- 3:57territorial governments to determine the best approach.
- 4:01Singh criticized the use of private nursing agencies by provincial governments, arguing
- 4:06that they contribute to a two-tier healthcare system.
- 4:10He pledged better compensation for nurses working within the public system as part of his
- 4:15strategy to strengthen Canada’s healthcare infrastructure.
- 4:19Although healthcare staffing is primarily a provincial responsibility, Singh stated that
- 4:24his party would link new federal health transfers to specific hiring and retention
- 4:28strategies.
- 4:29This approach aims to ensure that provinces and territories have the resources needed to
- 4:34bolster their healthcare workforce.
- 4:37The Canadian Nurses Association has also been vocal in the lead-up to the election, calling
- 4:42on all parties to establish a national licensing framework.
- 4:46Such a framework would provide nurses with the flexibility to work in regions where they are
- 4:50most needed, addressing disparities in healthcare access across the country.
- 4:56Polling conducted by Ipsos for Global News indicates that healthcare ranks third among
- 5:01voter priorities, following affordability and cost of living, as well as the economy.
- 5:06This highlights the significance of Singh’s promise and its potential impact on voters who
- 5:11are concerned about the future of healthcare in Canada.
- 5:16The relationship between technology use and cognitive health is a topic that has intrigued
- 5:20many, especially as the first generation widely exposed to technology reaches older age.
- 5:27A new meta-analysis study by researchers from two Texas universities, published in Nature
- 5:32Human Behavior, sheds light on this very issue.
- 5:36The study examined the hypothesis known as "digital dementia," which suggests that
- 5:42reliance on technology might weaken cognitive abilities over time.
- 5:47However, the findings challenge this hypothesis.
- 5:51The researchers analyzed fifty-seven studies involving over four hundred thousand older
- 5:56adults and discovered that technology use was associated with a forty-two percent lower risk
- 6:02of cognitive impairment.
- 6:04Cognitive impairment, in this context, included diagnoses of mild cognitive impairment or
- 6:09dementia, as well as subpar performance on cognitive tests.
- 6:14The types of technology examined included computers, smartphones, internet, email, and
- 6:20social media.
- 6:22Interestingly, the study found that these effects persisted even after adjusting for
- 6:28factors such as education, income, and other lifestyle elements, indicating that the
- 6:34protective effect of technology use might not be solely due to other brain health factors.
- 6:40Dr.
- 6:41Jared Benge, a co-lead study author, highlighted that this finding is encouraging,
- 6:47as it suggests that technology use may offer some net positive benefits to brain health.
- 6:53Despite the positive findings, the study's authors caution against assuming that all
- 6:57technology use is beneficial.
- 7:00Dr.
- 7:00Michael Scullin, another co-lead author, emphasized that the study does not endorse
- 7:05mindless scrolling or excessive use.
- 7:08Instead, it suggests that the generation that introduced us to the internet has found ways to
- 7:13derive cognitive benefits from these tools.
- 7:17There are still uncertainties about how different aspects of technology use impact
- 7:21brain health.
- 7:22The study did not delve into specific details about how participants used these technologies
- 7:27or how much time they spent on them, which leaves open questions about what types of use
- 7:32are most beneficial and whether there is a threshold for potential harm.
- 7:37The findings support the cognitive reserve theory, which argues that engaging in complex
- 7:41mental activities can lead to better cognitive well-being in older age, despite age-related
- 7:47brain changes.
- 7:49Dr.
- 7:50Amit Sachdev noted that technology might help reduce the risk of cognitive decline by keeping
- 7:55us neurologically active, and it can also promote social connections, which are essential
- 8:00for brain health.
- 8:02Experts advise that moderation is key when it comes to technology use.
- 8:07Engaging in activities that bring joy, genuine connection, creativity, and intellectual
- 8:13stimulation is beneficial.
- 8:16Dr.
- 8:17Sachdev pointed out that too much of anything can be detrimental, and it is important to
- 8:22identify the purpose and duration of technology use to maintain a healthy balance.
- 8:28For older adults hesitant about using technology, it is worth noting that even those
- 8:34with mild dementia can learn to use these tools.
- 8:38While it can be frustrating at times, this challenge reflects the mental stimulation that
- 8:43comes with learning something new, which can be beneficial for cognitive health.
- 8:49Today, we're going to explore a significant update in the field of childhood obesity care
- 8:54in Canada.
- 8:55For the first time in nearly two decades, the national clinical guidelines for managing
- 9:00childhood and adolescent obesity have been overhauled, and they're shifting away from
- 9:05focusing solely on numbers on a scale.
- 9:08This change is driven by a recognition of the complexities of obesity as a disease,
- 9:13emphasizing quality of life and mental health as pivotal aspects of treatment.
- 9:19These new guidelines, published in the Canadian Medical Association Journal, were developed
- 9:24with Obesity Canada and include ten recommendations and nine good practice
- 9:28statements.
- 9:30Importantly, they suggest the use of medications like glucagon-like peptide-1
- 9:34receptor agonists, such as Ozempic and Wegovy, for adolescents aged twelve and up who have
- 9:40obesity and have not been successful with weight loss through diet and exercise alone.
- 9:45However, these medications are not approved for younger children.
- 9:50Lisa Schaffer, the executive director of Obesity Canada, highlighted the shift in
- 9:56understanding obesity as more of a disease of the brain, necessitating early recognition and
- 10:01intervention.
- 10:03This new perspective aims to address obesity's true complexities as a chronic disease and
- 10:08emphasizes the necessity of updating clinical practice guidelines for pediatric obesity.
- 10:14The guidelines recognize obesity as a complex, chronic, and highly stigmatized disease that
- 10:20poses a risk for over two hundred health conditions.
- 10:25Alarmingly, rates of obesity are on the rise, with around twenty-five percent of children
- 10:30aged four to eleven and thirty-three percent of those aged twelve to seventeen having a body
- 10:35mass index that may indicate they are overweight or obese.
- 10:41The guidelines emphasize that more than fifty percent of children aged seven to eleven living
- 10:46with obesity will continue to do so into adolescence, and roughly eighty percent of
- 10:51teens aged twelve to eighteen will carry the condition into adulthood.
- 10:57The updated guidelines emphasize evidence-based options for managing obesity, focusing on
- 11:03shared decision-making between children, their families, and healthcare providers.
- 11:08While weight loss might be part of the journey, it's no longer the sole measure of success.
- 11:14Instead, multicomponent interventions that include physical activity, nutrition, and
- 11:20psychological support are recommended as the foundation of care.
- 11:25Where appropriate, medications or surgery may also play a role.
- 11:31The guidelines cautiously recommend glucagon-like peptide-1 medications for
- 11:36managing pediatric obesity, acknowledging that while these drugs can aid in weight loss and
- 11:41improve certain health markers, the long-term benefits and side effects remain unclear, and
- 11:46results can vary among individuals.
- 11:49Additionally, under specific conditions, the guidelines suggest that weight-loss surgeries,
- 11:56such as laparoscopic sleeve gastrectomy and gastric bypass, might be beneficial for
- 12:01adolescents aged thirteen and over.
- 12:04These surgeries work by limiting the stomach's capacity or altering digestion, leading to
- 12:09weight loss and health improvements when combined with behavioral and psychological
- 12:13support.
- 12:15However, they do come with risks, including mild side effects like nausea and, in rare
- 12:20cases, more serious complications.
- 12:24Dr.
- 12:25Sanjeev Sockalingam, the scientific director of Obesity Canada, noted the lack of equitable and
- 12:30affordable access to treatments in Canada, with only two surgical centers and a fragmented
- 12:35system of multidisciplinary obesity management clinics.
- 12:39He emphasized the importance of these guidelines as a foundation for advocating and
- 12:44educating towards establishing a new standard of obesity care for children and adolescents,
- 12:50ensuring they have access to evidence-based care to improve their health and wellbeing.
- 12:56These updates to the guidelines are a crucial step forward in addressing the complexities of
- 13:01childhood obesity, providing a holistic approach that considers the physical,
- 13:06psychological, and social dimensions of health.
- 13:10That's it for today's episode of Morning Medical with Dr.
- 13:13Chow.
- 13:14I hope you found the discussions enlightening and informative.
- 13:18Remember, health is a journey, not a destination, and staying informed is key to
- 13:24navigating it.
- 13:25Until next time, stay healthy and take care.
