California Sober, Dementia Risk Study, and High-Functioning Autism Debate · Morning Medical with Dr. Chow

0:00
Good morning, listeners, and welcome to Morning Medical with Dr.
0:03
Chow.
0:03
I'm Dr.
0:04
Chi-Ming Chow, and today we're diving into a fascinating topic that's stirring conversation
0:10
in the realm of addiction and harm reduction strategies.
0:13
We're exploring the concept of being "California Sober," a trend that's gaining
0:18
traction and recently received a bit of scientific backing.
0:22
So, what exactly does "California Sober" mean?
0:25
Essentially, it refers to a lifestyle choice where individuals reduce or eliminate alcohol
0:31
consumption in favor of using cannabis.
0:33
This approach has been popularized as a harm reduction strategy, and a recent study offers
0:39
some insights into its potential impact.
0:42
A study led by researchers at Brown University, published in the American Journal of
0:49
Psychiatry, explored the effects of cannabis on alcohol consumption.
0:54
The trial involved 157 participants, aged 21 to 44, who reported heavy alcohol use and regular
1:02
cannabis consumption.
1:04
Participants were randomized to smoke cannabis cigarettes with varying levels of
1:08
delta-9-tetrahydrocannabinol, or THC, the psychoactive component of cannabis.
1:16
The findings indicated that while smoking cannabis did not significantly reduce overall
1:21
alcohol cravings, it did decrease the short-term urge to drink when participants
1:26
consumed higher THC doses, specifically at 7.2 percent.
1:33
Interestingly, this reduction in urge was coupled with a relative decrease in alcohol
1:39
consumption in a controlled setting, with the higher THC group drinking less than those given
1:44
a placebo.
1:46
However, it's crucial to note that these results do not yet translate to a firm
1:50
recommendation for using cannabis as a substitute for alcohol.
1:55
The reduction in alcohol cravings was not significant across all measures, and
1:59
researchers caution that more studies are needed to understand the long-term effects of
2:05
substituting alcohol with cannabis.
2:08
There's also a concern that individuals could develop cannabis use disorder or experience
2:12
other cannabis-related issues over time.
2:16
Dr.
2:17
Jane Metrik, the lead researcher, emphasized the need for further investigation into the
2:22
conditions under which cannabis might help reduce alcohol consumption and the potential
2:27
risks involved.
2:29
It's a complex area, as cannabis can affect individuals differently; for some, it might
2:35
increase alcohol consumption, while for others, it could help them cut back.
2:41
From a clinical perspective, the study highlights the importance of screening for
2:45
concurrent cannabis use in patients addressing alcohol use disorders.
2:50
Understanding a patient's cannabis usage patterns can help clinicians monitor for any
2:55
progression into cannabis-related problems.
2:59
In summary, while the "California Sober" approach may offer some promise for reducing
3:05
alcohol consumption, it's not yet ready to be endorsed as a safe and effective alternative to
3:11
traditional methods of managing alcohol use disorder.
3:15
The ongoing research aims to further explore the therapeutic potential of cannabinoids and
3:20
their role in addiction treatment strategies.
3:25
Today, we're delving into a significant study that highlights the connection between physical
3:31
activity and dementia risk.
3:34
Researchers at Boston University, led by Doctor Phillip Hwang, explored how exercise at
3:40
different stages of life can impact the likelihood of developing dementia.
3:45
Their findings, published in JAMA Network Open, suggest that being physically active in midlife
3:52
and late life can substantially reduce the risk of dementia.
3:57
The study followed over four thousand three hundred participants from the Framingham Heart
4:03
Study Offspring cohort, who were initially free of dementia.
4:07
Participants were grouped by age: early adulthood, midlife, and late life, and their
4:13
physical activities were assessed at these stages.
4:16
The results were intriguing—higher levels of physical activity in midlife were linked to a
4:21
forty percent reduction in all-cause dementia risk over twenty-six years.
4:27
Similarly, those in the top two quintiles of late-life activity experienced a thirty-six to
4:32
forty-five percent lower risk of developing dementia over fifteen years.
4:37
Interestingly, the study found that exercise in early adulthood did not have the same
4:42
protective effect against dementia as activity in midlife and later years.
4:47
This suggests that the timing of when we engage in physical activity might be crucial for its
4:53
benefits in reducing dementia risk.
4:55
Doctor Hwang emphasized that identifying these critical periods can inform better prevention
5:00
strategies and interventions.
5:03
The mechanisms through which physical activity may reduce dementia risk include increased
5:08
cerebral blood flow, reduced inflammation, and enhanced neuroplasticity.
5:14
Moreover, exercise has been shown to boost brain-derived neurotrophic factor expression,
5:20
which is crucial for brain health.
5:22
These benefits may help explain why physical activity is considered an important modifiable
5:28
factor in dementia prevention.
5:31
The study also highlighted the role of the APOE4 gene, a known risk factor for Alzheimer’s
5:36
disease.
5:37
In midlife, higher activity levels were linked to lower dementia risk only in individuals
5:42
without the APOE4 gene.
5:44
However, in late life, physical activity was beneficial for both APOE4 carriers and
5:49
non-carriers, suggesting exercise might help offset some genetic risks associated with
5:54
dementia.
5:56
Although the study relied on self-reported physical activity, which could lead to some
6:01
misclassification, the long follow-up period and exclusion of prevalent dementia cases at
6:06
baseline strengthen the findings.
6:09
Nevertheless, the researchers acknowledge that higher mortality rates among less active and
6:15
older participants might have influenced the results.
6:19
In summary, this research underscores the importance of maintaining physical activity
6:24
throughout life, particularly in midlife and later years, to reduce the risk of dementia.
6:31
As we continue to explore the complexities of dementia prevention, understanding the impact
6:37
of lifestyle factors such as exercise will be key in developing effective strategies to
6:43
mitigate this growing public health challenge.
6:47
Today, we're taking a closer look at a topic that often comes up in discussions about
6:53
neurodiversity: high-functioning autism.
6:56
While it's not an official medical term or diagnosis, it's a phrase that some people use
7:02
to describe individuals with autism spectrum disorder who can manage day-to-day tasks with
7:08
minimal support.
7:09
This includes being able to speak, read, write, and handle basic life skills like eating and
7:16
dressing.
7:17
However, it's important to note that these abilities don't necessarily mean their autism
7:23
symptoms do not significantly impact their lives.
7:27
The term 'high-functioning autism' can be controversial because it can lead to
7:31
assumptions about someone's needs based on a label, which isn't always helpful.
7:37
Not everyone with autism is the same.
7:40
Some people prefer using terms like 'low support needs' and 'high support needs' to more
7:46
accurately describe where they fall on the autism spectrum.
7:50
This language reflects the level of assistance someone might require in their day-to-day life.
7:56
Autism spectrum disorder, or ASD, is a developmental brain condition that affects
8:02
communication and learning.
8:04
It encompasses a wide range of symptoms and abilities.
8:08
Many individuals with ASD can live independently, while others may have symptoms
8:13
that significantly affect their ability to care for themselves.
8:17
Historically, only those with severe symptoms were diagnosed with autism, but since the
8:23
1990s, milder forms have been recognized, including what was once known as Asperger's
8:28
syndrome.
8:30
Symptoms of what some call high-functioning autism can vary but often include difficulties
8:35
with social interactions, such as making direct eye contact or understanding social norms.
8:42
Individuals might prefer routine and feel anxious about unexpected changes.
8:48
They may also have trouble communicating their thoughts or feelings clearly and understanding
8:52
sarcasm or idioms.
8:55
These challenges can manifest differently in children and adults.
8:59
Diagnosing autism spectrum disorder involves several steps.
9:03
For children, doctors monitor development and behavior over time, looking for signs typical
9:09
of ASD.
9:11
Developmental screenings are recommended at specific ages, and if there are concerns, a
9:16
more detailed developmental diagnosis may follow.
9:19
This can involve assessments from specialists like child psychologists or speech-language
9:24
pathologists.
9:26
For adults, the diagnostic process is slightly different, often involving discussions about
9:31
social interactions, repetitive behaviors, and personal interests.
9:35
Doctors may also inquire about childhood behaviors and might involve family members to
9:40
gain insight.
9:41
While online tools like the Autism-Spectrum Quotient can help identify traits of autism,
9:47
they shouldn't be used for official diagnoses.
9:50
The rise in autism cases over recent years might be attributed to better screening tools
9:56
and increased awareness, as well as potential genetic and environmental factors.
10:01
As understanding of autism grows, so does the recognition of its diverse manifestations.
10:08
In terms of education and employment, individuals with autism spectrum disorder often
10:14
excel in fields like science, technology, engineering, math, and medicine.
10:21
However, they also face challenges such as lower college enrollment rates and high
10:26
unemployment.
10:28
This is often due to difficulties in social communication and potential biases during job
10:34
interviews.
10:35
In summary, while the term 'high-functioning autism' might be used informally to describe
10:41
certain individuals with ASD, it's important to approach each person as an individual with
10:47
unique needs and abilities.
10:49
Understanding and supporting these differences can help create more inclusive environments in
10:54
both educational and professional settings.
10:59
Alberta Premier Danielle Smith has announced her government's intention to introduce a new
11:03
health care model that would allow physicians to work in both public and private health care
11:07
systems simultaneously.
11:09
This plan, known as the "Dual Practice Surgery Model," is aimed at reducing wait times for
11:14
elective surgeries by increasing the number of surgeries that can be performed.
11:19
Smith highlighted this initiative in a video posted on social media, explaining that the
11:25
model is designed to provide physicians with the flexibility to perform additional elective
11:29
surgeries privately, beyond their public commitments.
11:33
The proposal outlines that surgeons and other surgical professionals would still be required
11:39
to perform a certain number of publicly funded surgeries each year.
11:43
However, they would also have the option to conduct extra surgeries in a private setting
11:48
during their weekends or off hours.
11:50
According to Smith, this approach would help move everyone on the public waitlist up in the
11:55
queue, allowing them to receive their publicly insured surgery more quickly than they
12:00
otherwise would.
12:02
Premier Smith emphasized that this model could also help retain doctors in Alberta and attract
12:08
back those who might have left the province for more lucrative opportunities elsewhere.
12:14
She assured that no Albertans would need to pay out-of-pocket to see their family doctor or to
12:19
get necessary treatment.
12:21
Smith pointed to countries like Sweden, Germany, and Australia, which operate under a
12:26
similar dual-model system, as examples of how this approach could work.
12:32
However, the plan has faced criticism.
12:37
The Canadian Medical Association has urged the Alberta government to reconsider the proposal,
12:44
expressing concerns that it could lead to longer wait times for patients, with some
12:49
having to pay twice for health care—once through taxes and again with their credit card.
12:56
Furthermore, the Alberta Medical Association stressed the importance of ensuring that any
13:01
reform is evidence-based and involves meaningful engagement with physicians,
13:07
patients, and stakeholders to avoid negatively impacting the public health care system.
13:13
Medical students from the Calgary Medical Students’ Association and the University of
13:17
Alberta’s Medical Students’ Association have also expressed their worries, stating that a
13:23
two-tiered system could disenfranchise Albertans who cannot afford private care.
13:29
They voiced their concerns about graduating into a health care system that might not be
13:33
equitable for all.
13:35
Critics have also raised concerns about potential conflicts with the Canada Health Act,
13:40
which prohibits charging for necessary services that are already publicly insured.
13:45
Some experts warn that this proposal could lead to legal challenges or a reduction in federal
13:51
health transfers if it's found to contravene the act.
13:55
Despite the controversy, some voices, like Nadeem Esmail from the Fraser Institute,
14:00
support the move, suggesting that it aligns Alberta with international norms where dual
14:05
systems are common.
14:07
He argues that this could allow Canadians to access private health care without having to
14:11
travel abroad, assuming they can afford it.
14:15
As Alberta moves forward with this plan, it remains to be seen how these changes will play
14:21
out in practice and how they will impact the province's health care landscape.
14:26
The debate continues over whether this dual practice model will indeed reduce wait times
14:32
and improve access to care, or if it will introduce new challenges to the health care
14:37
system.
14:40
Today, let's explore an innovative initiative that aims to bring cognitive assessment to the
14:46
forefront of primary care, a critical step given the rising prevalence of dementia.
14:52
As our population ages, the demand for effective cognitive care becomes more pressing.
14:58
Currently, more than 7 million Americans live with Alzheimer's disease, the most common form
15:04
of dementia, and this number is projected to double by the year 2060.
15:09
However, early-stage diagnoses remain alarmingly low, with only about eight percent
15:15
of those with mild cognitive impairment receiving a diagnosis.
15:21
Primary care clinicians are essential in detecting cognitive issues early, but they
15:25
often lack the necessary resources and training to effectively evaluate cognitive concerns.
15:30
This gap in care presents a significant opportunity to improve patient outcomes by
15:35
reaching individuals sooner, when interventions can have the greatest impact.
15:42
Distinguishing early cognitive impairment from normal aging is a complex challenge that
15:47
requires adequate tools and training.
15:50
In an effort to address these challenges, a team from the University of Washington, led by
15:55
Dr.
15:56
Barak Gaster, launched a two-year initiative designed to enhance cognitive assessment
16:01
capabilities among primary care providers.
16:05
This project, known as the Cognition in Primary Care program, was implemented across 14
16:10
community-based clinics, involving 94 primary care providers serving 330,000 patients in
16:17
Western Washington.
16:19
The results were remarkable.
16:22
Following the implementation of this program, there was a seven-fold increase in the use of
16:27
the Montreal Cognitive Assessment, a widely recognized cognitive testing tool.
16:33
The number of cognitive tests entered into health records rose from fewer than three to
16:39
nearly 20 per month.
16:40
More significantly, the number of patients diagnosed with mild cognitive impairment or
16:45
dementia more than doubled, increasing from six to 14 per month.
16:51
The Cognition in Primary Care program was tailored to fit the realities of primary care
16:55
practice, balancing practical demands with clinical rigor.
17:00
It included three brief educational sessions and a toolkit that combined computerized
17:05
checklists with paper forms to aid cognitive evaluations.
17:10
Importantly, the training extended beyond detection, offering practical strategies for
17:16
managing mild cognitive impairment and dementia, such as maintaining brain health and
17:21
managing behavioral symptoms.
17:24
This program not only provides a scalable, cost-effective model for primary care systems
17:30
but also aligns with the "4Ms" framework of age-friendly care, focusing on what matters
17:36
most to patients, medication safety, mental capacity, and mobility.
17:43
It also supports value-based care initiatives like Medicare's GUIDE model, which requires a
17:47
formal dementia diagnosis for enrollment.
17:51
Building on the success of this initiative, the team plans to partner with the American Academy
17:56
of Family Physicians to expand the program nationally, using an "office champions" model.
18:02
The goal is to introduce the program to 25 primary care offices and track its outcomes,
18:09
providing valuable insights for further expansion.
18:14
This coordinated effort is crucial as we strive to provide better cognitive care and support to
18:20
millions of American families.
18:23
Addressing the growing challenge of undiagnosed dementia is not only the right thing to do, but
18:28
a national imperative.
18:30
The financial burden of care for Alzheimer's disease is staggering, with lifetime costs
18:35
exceeding $400,000 per person and annual care costs reaching $232 billion.
18:41
By integrating cognitive care into everyday practice, we can ensure that individuals with
18:46
cognitive impairment receive the care they need and deserve.
18:51
As we wrap up today's episode, it's clear that everyone in the health system, including
18:56
government agencies and advocacy groups, has a role to play in strengthening cognitive care in
19:02
primary care settings.
19:04
By working together, we can make a significant difference in the lives of those affected by
19:09
dementia and their families.
19:11
Thank you for joining me today on Morning Medical with Dr.
19:15
Chow.
19:16
Stay informed and stay healthy.
19:18
Until next time, take care!
