The Mental Health Benefits of Going on Holiday

For better mental health, music and other forms of relaxation have been shown to have positive benefits. Now, researchers have identified a previously overlooked way to improve mental health – going on holiday, a luxury many have abandoned since COVID.

In a new cross-disciplinary paper, researchers from Edith Cowan University (ECU) propose that we view tourism, as not just as a recreational experience but as an industry that can provide real health benefits.

The interdisciplinary collaboration found that many aspects of going on holiday could have a positive impact on those with mental health issues or conditions.

Led by researcher Dr Jun Wen, a diverse team of tourism, public health and marketing experts investigated how tourism could benefit those living with dementia.

“Medical experts can recommend dementia treatments such as music therapy, exercise, cognitive stimulation, reminiscence therapy, sensory stimulation and adaptations to a patient’s mealtimes and environment,” Dr Wen said.

“These are all also often found when on holidays. This research is among the first to conceptually discuss how these tourism experiences could potentially work as dementia interventions.”

According to Dr Wen, the varied nature of tourism meant there were many opportunities to incorporate treatments for conditions such as dementia. Being in new environments and having new experiences could provide cognitive and sensory stimulation, for example.

“Exercise has been linked to mental wellbeing and travelling often involves enhanced physical activity, such as more walking,” Dr Wen said.

“Mealtimes are often different on holiday: they’re usually more social affairs with multiple people and family-style meals have been found to positively influence dementia patients’ eating behaviour.

“And then there’s the basics like fresh air and sunshine increasing vitamin D and serotonin levels. Everything that comes together to represent a holistic tourism experience, makes it easy to see how patients with dementia may benefit from tourism as an intervention.”

Dr Wen said COVID’s impact on travel in recent years had raised questions about tourism’s value beyond lifestyle and economic factors.

“Tourism has been found to boost physical and psychological wellbeing,” he said. So, after COVID, it’s a good time to identify tourism’s place in public health — and not just for healthy tourists, but vulnerable groups.”

Dr Wen said he hoped that new research could begin to examine how tourism can enhance the lives of people with various conditions.

“We’re trying to do something new in bridging tourism and health science,” he said. “There will have to be more empirical research and evidence to see if tourism can become one of the medical interventions for different diseases like dementia or depression.

“So, tourism is not just about travelling and having fun; we need to rethink the role tourism plays in modern society.”

The article ‘Tourism as a dementia treatment based on positive psychology’ was published in Tourism Management.

ECT Particularly Effective in Treating Severe Mania

Most patients with mania responded to electroconvulsive therapy (ECT), according to a Swedish study published in JAMA Network Open. Patients with more severe illness were also far more likely to respond to treatment, the study’s researchers found.

The study recruited 571 individuals who were in a manic episode treated with ECT, 482 (84.4%) responded. Of these, 28% of these patients were able to achieve remission of mania, the researchers found. ECT treatments were mostly given three times a week.

The patient group was 63% female, with a median age of 46. Most had mania with psychotic symptoms, and roughly a quarter were voluntarily admitted to the hospital, while 60% were involuntarily committed. About 45% had been exposed to prior ECT.

“These findings suggest that ECT may be a highly effective option for treating mania, which is in line with the literature reporting response rates of 56% to 100%,” the authors noted.

The severity of illness was associated with an increased chance of responding to ECT; 83% for markedly ill, 84% for severely ill, and 92% for extremely ill patients. Illness severity was graded according to Clinical Global Impression Improvement scale (CGI-I) score.

Additionally, patients who underwent more ECT treatments in an index series were significantly more likely to have a clinical response, with the greatest odds of response being among patients who received more than 9 treatments.

Clinical factors reducing a patient’s odds of responding to ECT included comorbid anxiety and comorbid obsessive compulsive disorder.

Factors not associated with a clinical response to ECT were age of mania onset, as well as psychopharmacotherapy before index admission, including lithium, lamotrigine, a first or second generation antipsychotic, valproate, benzodiazepine, antidepressant, anxiolytic, or a central stimulant.

“It is worth highlighting that 63% of patients in our study were treated with 1 or more antimanic agents before admission, suggesting that these treatments may not have been sufficient in reducing symptoms of mania,” the group noted.

Changes in Brain Structures Found in Patients with Anorexia Nervosa

On By ModernMedia

A major study published in the journal Biological Psychiatry has revealed key differences in brain structure between people with and without anorexia nervosa.

Anorexia nervosa is an eating disorder defined by restriction of energy intake relative to requirements, leading to a significantly low body weight. Patients will have an intense fear of gaining weight and distorted body image and are unable to recognise the seriousness of their significantly low body weight.

Little is known about why some people develop anorexia whilst others do not, although biological factors are widely recognised. The findings from the study, which was coordinated by neuroscientists at the University of Bath with international partners, draws on extensive analyses of brain scans taken from patients around the world and goes some way to answering the question.

They reveal that people with anorexia demonstrate ‘sizeable reductions’ in three critical measures of the brain: cortical thickness, subcortical volumes and cortical surface area. Brain size reductions are significant due the implied loss of brain cells or the connections between them.

The results are some of the clearest yet to show links between structural changes in the brain and eating disorders. The team says that the effect sizes in their study for anorexia are in fact the largest of any psychiatric disorder investigated to date.

This means that people with anorexia showed reductions in brain size and shape two to four times greater than people with conditions such as depression, ADHD, or OCD. The changes observed in brain size for anorexia may be attributable to reductions in body mass index (BMI).

The team emphasised the importance of early treatment to help people with anorexia avoid long-term, structural brain changes. Existing treatment typically involves forms of cognitive behavioural therapy and, critically, weight gain. Many people with anorexia are successfully treated and these results show the positive impact such treatment has on brain structure.

Their study pooled nearly 2000 pre-existing brain scans for people with anorexia, including people in recovery and ‘healthy controls’ (people neither with anorexia nor in recovery). For people in recovery from anorexia, the study found that reductions in brain structure were less severe, suggesting that, with appropriate early treatment and support, brain self-repair is possible.

Lead researcher, Dr Esther Walton of the Department of Psychology at the University of Bath explained: “For this study, we worked intensively over several years with research teams across the world. Being able to combine thousands of brain scans from people with anorexia allowed us to study the brain changes that might characterise this disorder in much greater detail.

“We found that the large reductions in brain structure, which we observed in patients, were less noticeable in patients already on the path to recovery. This is a good sign, because it indicates that these changes might not be permanent. With the right treatment, the brain might be able to bounce back.”

“The international scale of this work is extraordinary,” said Paul Thompson, a professor of neurology and lead scientist for the ENIGMA Consortium, an international effort to understand the link between brain structure, function and mental health. “Scientists from 22 centres worldwide pooled their brain scans to create the most detailed picture to date of how anorexia affects the brain. The brain changes in anorexia were more severe than in other any psychiatric condition we have studied. Effects of treatments and interventions can now be evaluated, using these new brain maps as a reference.”

He added: “This study is novel in term of the thousands of brain scans analysed, revealing that anorexia affects the brain more profoundly than any other psychiatric condition. This really is a wake-up call, showing the need for early interventions for people with eating disorders.”

Autoimmune Clue in Some Schizophrenia Cases

On By ModernMedia

Schizophrenia, which affects how people interact with reality, is difficult to treat because it has many possible causes. In a study published in Cell Reports Medicine, Japanese researchers have identified an autoantibody – an antibody which attacks the body’s own tissues – in some patients with schizophrenia.

Notably, they also found that this autoantibody caused schizophrenia-like behaviours and changes in the brain when they injected it into mice.

When considering possible autoantibodies that might cause schizophrenia, researchers from Tokyo Medical and Dental University (TMDU) had a specific protein in mind. Previous research has suggested that neural cell adhesion molecule (NCAM1), which helps facilitate synaptic connections, may have a role in the development of schizophrenia.

“We decided to look for autoantibodies against NCAM1 in around 200 healthy controls and 200 patients with schizophrenia,” explained lead author of the study Hiroki Shiwaku. “We only found these autoantibodies in 12 patients, suggesting that they may be associated with the disorder in just a small subset of schizophrenia cases.”

The research went on to find out whether these autoantibodies could cause any changes that commonly occur in schizophrenia, so they purified autoantibodies from some of the patients and injected them into the brains of mice.

“The results were impressive,” said the study’s senior author, Hidehiko Takahashi. “Even though the mice only had these autoantibodies in their brains for a short time, they had changes in their behaviour and synapses that were similar to what is seen in humans with schizophrenia.”

The mice given the patient autoantibodies had cognitive impairment and changes in their regulation of the startle reflex, which are both seen in other animal models of schizophrenia. They also had fewer synapses and dendritic spines, which are structures that are important for the connections between brain cells, and are also affected in schizophrenia.

The study findings hold promise for the diagnosis and treatment of schizophrenia can present very differently among patients and is often resistant to treatment. If schizophrenia is indeed caused by autoantibodies against NCAM1 in some patients, this will lead to important improvements in their diagnosis and treatment.

LSD Microdosing Trips up in Randomised Controlled Study

On By ModernMedia

A randomised controlled study of LSD microdosing in healthy adults found no evidence of improvements to mood or cognition, which are some of its purported benefits. Other benefits were found to steadily decrease with time. The research has been published in the journal Addiction Biology.

‘Microdosing’ involves taking small amounts of a psychedelic drug at regular intervals. Preliminary research has indicated that microdosing is associated with a range of psychological benefits, such as increased productivity and reduced stress, but the gold standard for proving causation – randomised placebo-controlled studies – had not yet been done.

“I saw how widespread the practice of microdosing is, and yet there are few well-controlled studies to document its apparent benefits,” said study author Harriet de Wit, a professor of psychiatry and behavioral neuroscience at the University of Chicago. “My human psychopharmacology laboratory is well suited to test effects of drugs under double-blind conditions.”

In the study, four low doses of LSD (13 or 26 μg) or placebo were administered to 56 healthy adults at 3–4 day intervals. The participants were aged 18–35 and they all reported having used a psychedelic drug at least once in their lifetime, but were not experienced with microdosing. The doses were administered under double-blind conditions, meaning that neither the participants nor the researchers knew who was receiving an active dose and who was receiving an inactive placebo.

“We removed any expectations that this was a psychedelic drug,” Prof de Wit explained. “Because in the real world, people’s expectations can strongly influence their responses.”

After ingesting their dose, the participants completed cardiovascular assessments and hourly mood questionnaires. During the first and last sessions, the participants also completed cognitive and behavioral tasks related to emotional processing, working memory, simulated social rejection, and general cognitive performance.

Participants received their dose during five-hour laboratory sessions. They remained in a comfortable room and were given access to movies and reading materials when no activities were scheduled.

The researchers found that the higher dose of LSD (26 μg) produced a small decrease in false alarm rates for recognising fearful emotions and a small decrease in feelings of social rejection. The higher dose of LSD also produced heightened feelings of vigor and some participants who received the higher dose reported feeling a modest “high” during the drug sessions.

But neither the lower or higher doses of LSD had a significant effect on other aspects of emotional processing, mood, working memory, or general cognitive performance. “Under these limited conditions, the effects did not differ from placebo. But, future studies are needed to assess the effects of repeated doses under different conditions,” de Wit told PsyPost.

The participants also appeared to build a tolerance to LSD over the course of the study, with the strongest “high” reported at the first session, and the perception of a drug effect diminishing at each subsequent session.

“We can’t say necessarily that microdosing doesn’t work,” Prof de Wit said in a news release. “All we can say is that, under these controlled circumstances, with this kind of participant, these doses, and these intervals, we didn’t see a robust effect.”

There are more questions to explore in future research “Does microdosing have more pronounced effects in individuals with anxiety or depression, or pressing psychological problems?” Prof de Wit said. “Would the effects be detected if different outcome measures were used, or if dosing continued for more than 2 weeks?”

IBD and Depression is a Two-way Street

On By ModernMedia

While irritable bowel disease (IBD) and depression are known to occur together, scientists report a clinical overlap of these conditions in the Journal of Gastroenterology and Hepatology, implying the existence of a two-way relationship. Patients diagnosed with IBD were nine times as likely to develop depression than the general population. Their siblings who did not suffer from IBD were almost two times as likely to develop depression.

Conversely, patients with depression were two times as likely to develop IBD, and their siblings without depression were more than one and a half times as likely to develop IBD.

“This research reveals a clinical overlap between both conditions, and is the first study to investigate the two-way association between IBD and depression in siblings,” said Bing Zhang, MD, a gastroenterologist with Keck Medicine and co-lead author of the study.

The researchers drew on the data of more than 20 million people from Taiwan’s National Health Insurance Research Database. For 11 years, they tracked patients with either IBD or depression and their siblings without either condition, comparing onset of depression or IBD with a control group of people without either condition, but with similar age, sex and socioeconomic status.

Zhang hypothesises that many factors may contribute to the bidirectional nature of the disorders, including environmental stressors, the gut microbiome and genetics.

“The finding that people with IBD are more prone to depression makes sense because IBD causes constant gastrointestinal symptoms that can be very disruptive to a patient’s life,” he said. “And the elevated depression risk among siblings of IBD patients may reflect caregiver fatigue if the siblings have a role in caring for the patient.”

What surprised researchers was that patients with depression were prone to IBD. Zhang speculates that this discovery may have to do with what is known as the gut-brain axis, a scientifically established connection between the gastrointestinal system and the central nervous system, which consists of the spinal cord and the brain.

For example, he said, inflammation of the brain, which plays a role in depression, may be linked to the inflammation of the gastrointestinal tract, a hallmark of IBD.

The researchers are not sure why siblings of patients with depression are more likely to be diagnosed with IBD. Zhang surmises that there may be a shared genetic susceptibility for either disease that presents differently in family members.

Zhang hopes that the study findings will encourage health care professionals to take both family history and the relationship between gastrointestinal and mood disorders into consideration when evaluating or treating patients with either IBD or depression.

Through more research and better understanding of the gut-brain axis, he envisions leveraging the newfound connection between the conditions to improve the prevention, diagnosis and treatment of IBD and mental disorders.

Study Reveals Higher Suicide Rates among Pharmacists

On By ModernMedia

While the COVID pandemic put the spotlight on the issue of mental health and burnout among doctors and nurses, less was known about the mental health of pharmacists. Results of a longitudinal study published in the Journal of the American Pharmacists Association reveal a suicide rate among pharmacists nearly twice that of the general population.

The figures are based on data from 2003 through 2018, show a suicide rate of 20 per 100 000 pharmacists compared to 12 per 100 000 in the general population. Study authors expect numbers to be even higher in subsequent years due to the additional stressors of the pandemic, and are currently evaluating more recent data.

“If we learned anything from the pandemic, it’s that there is a breaking point for health professionals,” said corresponding author Kelly C. Lee, PharmD, professor at UC San Diego.

The study identified the most common means of suicide in this population, with 49.8% of cases involving firearms, 29.4% involving poisoning and 13% involving suffocation. The use of firearms was similar between pharmacists and the general population, but poisoning via benzodiazepines, antidepressants and opioids was more frequent among pharmacists.

The data also provide some insight into contributing factors, including a history of mental illness and a high prevalence of job problems. Job problems are the most common feature of suicides across health care professions.

For pharmacists, Lee said job problems reflect significant changes in the industry in recent years, with more pharmacists being employed by hospitals and chain retailers as opposed to the small, private pharmacies more common in the past. Pharmacist responsibilities have also grown considerably, with larger volumes of pharmaceuticals to dispense and increasing demands to administer vaccines and other health care services.

“Pharmacists have many more responsibilities now, but are expected to do them with the same resources and compensation they had 20 years ago,” said Prof Lee. “And with strict monitoring from state and federal regulatory boards, pharmacists are expected to perform in a fast-paced environment with perfect accuracy. It’s difficult for any human to keep up with that pressure.”

Future research will further evaluate which job problems have the biggest impact and how the field can better respond. In the meantime, Prof Lee advised pharmacists to encourage help-seeking behaviours amongst themselves and their colleagues.

“Mental health is still highly stigmatised, and often even more so among health professionals,” said Prof Lee. “Even though we should know better, there is such an expectation to appear strong, capable and reliable in our roles that we struggle to admit any vulnerabilities. It’s time to take a look at what our jobs are doing to us and how we can better support each other, or we are going to lose our best pharmacists.”

Mental Health Conditions Disrupt Blood Pressure and Heart Rate

On By ModernMedia

A new study published in BioMedical Engineering has revealed that mental health is closely aligned to blood pressure and heart rate variations. The researchers found that mental illness could cause widely fluctuating blood pressure, which can lead to cardiovascular disease and organ damage.

University of South Australia researcher Dr Renly Lim and colleagues said there is clear evidence that mental illness interferes with the body’s autonomic functions, including blood pressure, heart rate, temperature and breathing.

“We reviewed 12 studies on people with anxiety, depression and panic disorders and found that, regardless of age, mental said is significantly associated with greater blood pressure variations during the day,” Dr Lim says.

“We also found that for people who are mentally ill, their heart rate does not adapt to external stressors as it should.

“Contrary to what many people think, a healthy heart is not one that beats like a metronome. Instead, it should adjust to withstand environmental and psychological challenges. A constantly changing heart rate is actually a sign of good health.”

Reduced heart rate variation (HRV) is common in people with mental illness and indicates that the body’s stress response is poor, exacerbating the negative effects of chronic stress.

Unlike normally consistent heart rates, HRV is more complex and is the time between two heartbeats, which should change according to external stressors.

“What we aim for is not a constantly changing heart rate but a high heart rate variation. This is achieved through a healthy diet, exercise, low stress and good mental health.”

Low HRV occurs during ‘fight-or-flight’ mode, or in those who are easily stressed and is common in people with chronic diseases, including cardiovascular and mental health problems.

While large blood pressure variations (BPV) during the day are not ideal, at night the systolic pressure should dip by between 10–20% to allow the heart to rest. People with mental health issues were found to have an insufficient BP drop at night, dropping less than 10%.

The reduced dipping can be caused by many factors, including autonomic dysfunction, poor quality of sleep and disrupted circadian rhythms that regulate the sleep-wake cycle.

“The takeout from this study is that we need to pay more attention to the physical impacts of mental illness,” Dr Lim said.

“It is a major global burden, affecting between 11–18 per cent (one billion) of people worldwide. Since mental illness can contribute to the deterioration of heart and blood pressure regulation, early therapeutic intervention is essential.”

Social Media Breaks Relieve Mental Health and Free up Time

On By ModernMedia

Advising people to take a week-long social media break could lead to significant improvements in their wellbeing, depression and anxiety and could become a recommended part of maintaining mental health, according to the authors of a study published in Cyberpsychology, Behavior and Social Networking.

University of Bath researchers studied the mental health effects of a week-long social media break. Some participants were able to free up 9 hours a week of time otherwise spent scrolling Instagram, Facebook, Twitter and TikTok.

Their results suggest that just one week off social media improved individuals’ overall level of well-being, as well as reduced symptoms of depression and anxiety.

For the study, the researchers randomly allocated 154 individuals aged 18 to 72 who used social media every day into either an intervention group, where they were asked to stop using all social media for one-week or a control group, where they could continue scrolling as normal. At the beginning of the study, baseline scores for anxiety, depression and wellbeing were taken.

At the start of the study, average time spend on social media was 8 hours per week. After one week, the participants who were asked to take the one-week break had significant improvements in wellbeing, depression, and anxiety than those who continued to use social media, suggesting a short-term benefit.

Participants asked to take a one-week break reported using social media for an average of 21 minutes’ use compared to seven hours for the control group, with screen usage stats used to confirm adherence to the break. Lead researcher from Bath’s Department for Health, Dr Jeff Lambert explained: “Scrolling social media is so ubiquitous that many of us do it almost without thinking from the moment we wake up to when we close our eyes at night.

“We know that social media usage is huge and that there are increasing concerns about its mental health effects, so with this study, we wanted to see whether simply asking people to take a week’s break could yield mental health benefits.

“Many of our participants reported positive effects from being off social media with improved mood and less anxiety overall. This suggests that even just a small break can have an impact.

“Of course, social media is a part of life and for many people, it’s an indispensable part of who they are and how they interact with others. But if you are spending hours each week scrolling and you feel it is negatively impacting you, it could be worth cutting down on your usage to see if it helps.”

The team’s next steps include investigating short breaks in different populations (eg younger people) and to increase follow up time. If benefits persist, they speculate that this could help in mental health management.

Over the past 15 years, social media has undergone explosive growth. In the UK the number of adults using social media increased from 45% in 2011 to 71% in 2021. As many as 97% of 16 to 44-year-olds use social media, with scrolling being most frequent online activity.

Feeling ‘low’ and losing pleasure are core characteristics of depression, whereas anxiety is characterised by excessive and out of control worry. Wellbeing refers to an individual’s level of positive affect, life satisfaction and sense of purpose. According to the UK mental health organisation Mind, one in six people experience a common mental health problem like anxiety and depression in any given week.

GI Issues and Anxiety Linked in Children with Autism

On By ModernMedia

A new study has found a bi-directional relationship between gastrointestinal (GI) issues and internalised symptoms such as anxiety in children and adolescents with autism, which means the symptoms seem to be affecting each other. The findings could inform future precision medicine research aimed at developing personalised treatments for people with autism experiencing gastrointestinal issues. The study appears in the Journal of Autism and Developmental Disorders.

Autism is known to be often associated with GI issues, and is often overlooked in children despite being a source of pain and anxiety. Food preferences are often for carbohydrates and processed foods. The most common cause of GI issues in children with autism are abdominal pain, constipation, chronic diarrhea and gastroesophageal reflux disease (GERD).

“Research has shown gastrointestinal issues are associated with an increased stress response as well as aggression and irritability in some children with autism,” said Brad Ferguson, an assistant research professor. “This likely happens because some kids with autism are unable to verbally communicate their gastrointestinal discomfort as well as how they feel in general, which can be extremely frustrating. The goal of our research is to find out what factors are associated with gastrointestinal problems in individuals with autism so we can design treatments to help these individuals feel better.”

In the study, Ferguson and his team analysed health data from more than 620 under-18 patients with autism who experience gastrointestinal issues. Then, the researchers examined the relationship between the GI issues and internalised symptoms. Ferguson explained the findings provide more evidence on the importance of the ‘gut–brain axis’ in GI disorders in individuals with autism.

“Stress signals from the brain can alter the release of neurotransmitters like serotonin and norepinephrine in the gut which control gastrointestinal motility, or the movement of stool through the intestines. Stress also impacts the balance of bacteria living in the gut, called the microbiota, which can alter gastrointestinal functioning,” Ferguson said. “The gut then sends signals back to the brain, and that can, in turn, lead to feelings of anxiety, depression and social withdrawal. The cycle then repeats, so novel treatments addressing signals from both the brain and the gut may provide the most benefit for some kids with gastrointestinal disorders and autism.”

Ferguson is collaborating with David Beversdorf, a neurologist who also studies gastrointestinal problems in individuals with autism. Beversdorf had recently helped identify specific RNA biomarkers linked with gastrointestinal issues in children with autism.

“Interestingly, the study from Beversdorf and colleagues found relationships between microRNA that are related to anxiety behaviour following prolonged stress as well as depression and gastrointestinal disturbance, providing some converging evidence with our behavioural findings,” Ferguson said.

Ferguson and Beversdorf are now together investigating the effects of a stress-reducing medication on GI issues in a clinical trial. Ferguson cautioned that treatment could be effective for certain people with autism but not others.

“Our team uses a biomarker-based approach to find what markers in the body are common in those who respond favourably to certain treatments,” Ferguson said. “Our goal is to eventually develop a quick test that tells us which treatment is likely to work for which subgroups of patients based on their unique biomarker signature, including markers of stress, composition of gut bacteria, genetics, co-occurring psychological disorders, or a combination thereof. This way, we can provide the right treatments to the right patients at the right time.”
