  Hello, and welcome to Morning Medical with Dr.
• 0:02
  Chow.
• 0:03
  I'm your host, Dr.
• 0:05
  Chi-Ming Chow.
• 0:06
  In today's episode, we're diving into some intriguing findings from the world of
• 0:10
  endocrinology, specifically focusing on thyroid health.
• 0:14
  For many older adults, a common thyroid medication might not be as necessary as once
• 0:19
  thought.
• 0:20
  Let's take a closer look at a recent study that suggests some older patients may be able to
• 0:26
  discontinue their thyroid medication under certain conditions.
• 0:33
  A new study conducted in the Netherlands has revealed that a significant portion of older
• 0:38
  adults might not need to be on levothyroxine, a commonly prescribed thyroid hormone replacement
• 0:44
  therapy, for life.
• 0:46
  The study found that under careful physician supervision, approximately 26 percent of older
• 0:51
  patients were able to stop taking levothyroxine while maintaining stable thyroid hormone levels
• 0:56
  for a year.
• 0:58
  The research, led by Dr.
• 1:00
  Rosalinde Poortvliet and her colleagues at Leiden University Medical Center, involved a
• 1:05
  protocol for stepwise reduction in levothyroxine.
• 1:09
  It showed that around 25.7 percent of patients aged 60 and above successfully discontinued the
• 1:16
  medication while keeping their thyroid-stimulating hormone, or TSH, levels
• 1:22
  under 10 milli-international units per liter and their free thyroxine levels within the
• 1:27
  normal range.
• 1:28
  Interestingly, the study highlighted that patients who were on lower doses of
• 1:32
  levothyroxine at the start were more likely to successfully stop taking the medication.
• 1:38
  Nearly two-thirds of those on a daily dose of 50 micrograms or less managed to discontinue
• 1:44
  treatment.
• 1:45
  This suggests that lower initial doses might predict a better outcome for discontinuation.
• 1:51
  The importance of this study lies in its potential to reshape how we approach thyroid
• 1:55
  hormone therapy in older adults.
• 1:58
  Current guidelines often lack clear protocols for deprescribing levothyroxine, which can lead
• 2:03
  to overtreatment.
• 2:04
  This is particularly concerning as past research has linked long-term use of
• 2:09
  levothyroxine to increased risks of fractures, atrial fibrillation, and cognitive issues.
• 2:15
  Dr.
• 2:16
  Maria Papaleontiou from the University of Michigan and Dr.
• 2:20
  Anne Cappola from the University of Pennsylvania emphasize the need for clinicians
• 2:25
  to reassess the necessity of thyroid hormone therapy in older adults.
• 2:30
  They recommend embracing a patient-centered, evidence-based approach to deprescribing, which
• 2:35
  could significantly reduce the risks associated with overtreatment.
• 2:39
  The study followed 370 older adults in primary care settings, all of whom had been on a stable
• 2:46
  dose of levothyroxine for at least a year.
• 2:49
  The inclusion criteria were quite specific, ensuring that the participants had a TSH level
• 2:55
  under 10 milli-international units per liter.
• 2:59
  The study's findings suggest that with careful monitoring and a structured reduction protocol,
• 3:05
  some older patients may not need lifelong thyroid hormone replacement therapy.
• 3:10
  While these findings are promising, it's crucial to note that the decision to
• 3:14
  discontinue levothyroxine should always be made in consultation with a healthcare professional.
• 3:20
  Each patient's situation is unique, and factors such as the initial reason for thyroid hormone
• 3:26
  therapy and individual thyroid function must be considered.
• 3:30
  In summary, this study provides an exciting glimpse into the potential for re-evaluating
• 3:35
  thyroid treatment in older adults, highlighting the importance of personalized medicine.
• 3:40
  By carefully assessing each patient's needs, we can optimize their care and reduce unnecessary
• 3:46
  medication use.
• 3:49
  Let's shift gears and explore something a bit different yet equally insightful.
• 3:54
  Have you ever thought about how the art of bonsai could inspire us to create a healthier,
• 3:59
  more efficient healthcare system?
• 4:01
  It might sound a bit unconventional, but let's delve into how the principles of bonsai
• 4:07
  cultivation could offer a fresh perspective on healthcare reform.
• 4:12
  Bonsai, the ancient Japanese art of growing miniature trees in containers, requires
• 4:17
  meticulous care and a clear vision for the future.
• 4:22
  It's about shaping and guiding the tree to grow in a specific direction, often involving
• 4:27
  pruning and trimming to encourage healthy growth.
• 4:31
  This approach isn't just about aesthetics; it's about fostering balance and harmony, nurturing
• 4:37
  something small to develop into its best form.
• 4:41
  Now, consider our healthcare system.
• 4:44
  Like a bonsai tree, it needs careful tending and sometimes a bit of pruning to thrive.
• 4:50
  Our current system is vast and complex, often laden with inefficiencies, redundancies, and
• 4:57
  unnecessary procedures that don't necessarily add value to patient care.
• 5:02
  Just as a bonsai tree needs careful planning and regular maintenance, our healthcare system
• 5:07
  could benefit from thoughtful revisions and strategic cuts to improve its overall health
• 5:12
  and functionality.
• 5:15
  Imagine having a vision for healthcare that, like a bonsai, focuses on long-term growth and
• 5:20
  sustainability.
• 5:21
  This means envisioning what a healthier system looks like and making deliberate choices to get
• 5:25
  there.
• 5:26
  It involves reevaluating processes, cutting back on wasteful practices, and redirecting
• 5:31
  resources where they're most needed.
• 5:33
  This could mean reducing unnecessary tests and treatments, streamlining operations, and
• 5:39
  emphasizing preventive care.
• 5:42
  The idea is not to cut for the sake of cutting, but to shape the system in a way that maximizes
• 5:47
  its potential to serve everyone effectively.
• 5:50
  Just as the bonsai requires the right balance of sunlight, water, and nutrients to flourish,
• 5:56
  our healthcare system needs the right mix of resources, policies, and patient-centered care
• 6:01
  to truly meet the needs of the population.
• 6:05
  It's a daunting task, much like sculpting a bonsai tree into a work of art, but with
• 6:10
  careful planning and commitment, it's possible to transform our healthcare system into one
• 6:15
  that is more adaptable, efficient, and responsive to the needs of patients.
• 6:20
  By embracing this mindset, we can hope to cultivate a system that not only survives but
• 6:25
  thrives, much like a well-tended bonsai.
• 6:30
  Let's turn our attention to an enlightening study that explores the impact of sedentary
• 6:34
  behavior on brain health.
• 6:37
  It's not just how much time you spend sitting that matters, but what you're doing while
• 6:42
  you're sitting that can affect your health.
• 6:45
  A recent study has revealed that passive screen time—such as watching television—might be
• 6:51
  linked to a higher risk of developing dementia.
• 6:53
  On the other hand, more mentally engaging activities, like doing crossword puzzles, seem
• 6:59
  to offer some protection against cognitive decline.
• 7:03
  This study, published in the American Journal of Preventive Medicine, followed over 20,000
• 7:09
  adults in Sweden for nearly two decades.
• 7:12
  The research aimed to understand how different types of sedentary behaviors are associated
• 7:17
  with the risk of developing dementia.
• 7:19
  Participants, aged between 35 and 64 at the start, reported their sitting habits and the
• 7:26
  activities they engaged in during that time.
• 7:29
  The study found that 569 individuals were diagnosed with dementia over the study period.
• 7:36
  A key finding was the distinction between mentally passive and mentally active sedentary
• 7:41
  behaviors.
• 7:42
  Mentally passive activities, like watching television or listening to music without
• 7:46
  interaction, were linked to a significantly higher risk of developing dementia.
• 7:51
  Conversely, engaging in mentally active behaviors, such as reading, doing puzzles, or
• 7:57
  participating in hobbies like knitting or sewing, was associated with a lower risk.
• 8:02
  Interestingly, the study modeled the effects of changing behavior.
• 8:08
  It suggested that replacing just one hour of passive sedentary time with an hour of mentally
• 8:14
  active behavior could reduce dementia risk by about seven percent.
• 8:19
  Adding an hour of mentally engaging activities overall was associated with a four percent
• 8:24
  reduction in risk.
• 8:26
  Moreover, combining mental engagement with physical activity showed an even greater
• 8:30
  benefit, reducing the risk by eleven percent.
• 8:34
  So, what exactly counts as mentally passive versus mentally active behavior?
• 8:40
  In this context, mentally passive activities involve little cognitive effort.
• 8:46
  Think of activities like watching television or listening to music passively.
• 8:51
  Mentally active behaviors, on the other hand, require attention and problem-solving.
• 8:57
  These include activities like reading, doing puzzles, or working on a computer in a way that
• 9:03
  involves thinking.
• 9:05
  Why might passive activities be linked to a higher dementia risk?
• 9:09
  One explanation is that the brain benefits from being challenged.
• 9:14
  Cognitive engagement helps maintain neural connections and may support cognitive reserve,
• 9:19
  which is the brain's ability to adapt and compensate for changes over time.
• 9:24
  Long periods of inactivity might mean those neural pathways aren't being stimulated,
• 9:29
  potentially contributing to cognitive decline.
• 9:33
  Moreover, passive activities often involve prolonged sitting, which can reduce blood flow
• 9:38
  to the brain.
• 9:40
  In contrast, engaging activities usually involve small shifts in attention or movement,
• 9:46
  which can be beneficial.
• 9:48
  Mentally stimulating activities are often more social or interactive, which has been
• 9:53
  associated with better cognitive outcomes.
• 9:57
  Additionally, poor sleep quality, often linked with passive activities, is increasingly
• 10:02
  recognized as important for long-term brain health.
• 10:06
  The study doesn't prove that passive activities directly cause dementia, but it does highlight
• 10:11
  a strong association.
• 10:14
  It's possible that people with better baseline cognitive function are more inclined to choose
• 10:19
  mentally engaging activities.
• 10:22
  Nonetheless, the findings emphasize the importance of choosing activities that require
• 10:27
  active thinking, such as reading a book, doing a crossword puzzle, or learning a new skill.
• 10:33
  Even everyday tasks can be made more cognitively engaging by adding a challenge,
• 10:38
  like trying a new recipe or practicing a new language.
• 10:42
  Social interaction, which is often part of mentally engaging activities, has been
• 10:46
  consistently linked to better cognitive health and lower dementia risk.
• 10:51
  Is all screen time harmful?
• 10:53
  Not necessarily.
• 10:55
  It depends on how it's used.
• 10:57
  Watching television for long periods without interaction is considered passive.
• 11:02
  However, using a computer to solve problems or learn new skills can be mentally stimulating.
• 11:09
  The study's concern isn't about screens per se, but prolonged low-engagement behavior, like
• 11:14
  mindless scrolling on social media.
• 11:17
  Both physical and mental activities are crucial for reducing dementia risk.
• 11:21
  While physical activity is well-known for its brain health benefits, this study highlights
• 11:26
  the importance of mental engagement during sedentary time.
• 11:30
  Combining physical activity with mentally engaging behaviors appears to provide the
• 11:35
  greatest reduction in dementia risk.
• 11:38
  The key takeaway is that small, everyday choices can significantly impact long-term
• 11:43
  cognitive health.
• 11:44
  Reducing passive behavior and replacing it with mentally engaging activities, while maintaining
• 11:50
  overall health through physical activity, good cardiovascular health, a nutritious diet, and
• 11:55
  adequate sleep, can support brain health over the years.
• 12:00
  In our final segment today, we're delving into the world of social media and its impact on
• 12:06
  mental health information, particularly concerning Attention Deficit Hyperactivity
• 12:11
  Disorder and autism.
• 12:13
  A recent study has uncovered that a significant portion of content related to these conditions
• 12:18
  on platforms like TikTok is misleading or not supported by scientific evidence.
• 12:24
  The study, published in the Journal of Social Media Research, reveals that 52 percent of
• 12:29
  top-performing videos about Attention Deficit Hyperactivity Disorder and 41 percent of
• 12:35
  autism-related videos on TikTok contain inaccurate information.
• 12:40
  Researchers at the University of East Anglia's Norwich Medical School found that these
• 12:45
  platforms, including YouTube, Facebook, Instagram, and X, formerly known as Twitter,
• 12:51
  are rife with misleading mental health content, with TikTok being the standout offender.
• 12:57
  Much of this content is based on personal anecdotes and simplified traits rather than
• 13:02
  established diagnostic criteria.
• 13:05
  This kind of information can easily spread due to the engaging nature of these videos, even if
• 13:10
  the content is not accurate.
• 13:13
  Eleanor Chatburn, a clinical psychologist and senior author of the study, emphasizes that
• 13:18
  while social media is a valuable tool for young people learning about mental health, the
• 13:23
  quality of the information is highly variable.
• 13:27
  Darren O'Reilly, a consultant psychologist, notes that TikTok's format rewards fast,
• 13:32
  emotionally engaging content rather than careful, evidence-based information.
• 13:37
  As a result, people might find these videos relatable and validating, but they risk
• 13:42
  mistaking this for clinical accuracy.
• 13:44
  This is particularly true for conditions like Attention Deficit Hyperactivity Disorder and
• 13:49
  autism, where traits can overlap with common experiences such as stress or anxiety, leading
• 13:56
  to oversimplification and potential misdiagnosis.
• 14:00
  The spread of inaccurate mental health information can lead to confusion,
• 14:04
  misdiagnosis, and delayed support.
• 14:07
  People might pursue incorrect diagnoses or dismiss symptoms that need attention.
• 14:13
  O'Reilly points out that distinguishing between normal human experiences and clinical
• 14:17
  conditions is crucial, as mislabeling can lead to unnecessary anxiety and inappropriate
• 14:23
  interventions.
• 14:25
  While social media has helped raise awareness about mental health and neurodivergence, it's
• 14:30
  essential that this awareness is balanced with accuracy.
• 14:36
  O'Reilly stresses that while visibility can encourage people to seek help, it should not
• 14:40
  substitute for professional assessment.
• 14:43
  Conditions like Attention Deficit Hyperactivity Disorder and autism are complex and cannot be
• 14:48
  reduced to a few traits.
• 14:51
  So, how can you spot misinformation on social media?
• 14:54
  If a video claims that a single trait means you have Attention Deficit Hyperactivity Disorder
• 14:59
  or autism, it's likely misleading.
• 15:03
  Real diagnoses are based on patterns and histories, not just one behavior.
• 15:09
  Look for content from creators with relevant clinical training or those who cite credible
• 15:13
  sources.
• 15:15
  Avoid content that offers quick fixes or speaks in absolutes.
• 15:20
  For reliable information, seek out regulated professionals such as clinical psychologists or
• 15:26
  psychiatrists.
• 15:27
  Comprehensive assessments should involve developmental histories and consider
• 15:31
  alternative explanations, rather than relying solely on symptom checklists.
• 15:37
  As we wrap up today's episode, remember that while social media can offer support and
• 15:42
  community, it's important to approach the information you find with a critical eye.
• 15:46
  Ensuring that your mental health information is accurate and evidence-based can help you make
• 15:51
  informed decisions about your health.
