Bulimia Experience as a Teen Shaped Man’s Healthy Recipe Project

On By ModernMedia

A UK man who started a project coming up with gut-healthy-recipes said that it was “shaped” by his having had bulimia in his teenage years.

Clinician and scientist Dr Sunni Patel, 35, said as a teen he thought he was “chubby” and experienced the eating disorder when he was aged 15 to 18.

Binge eating was his “solace” he said, and he used religious fasting “as a cover”.

Dr Patel started a website sharing recipes, and he urged people not to underestimate how gut health affects mental health.

“I’d find comfort and my escapism via food.”
Dr Sunni Patel

He said he would fast for four days a week, eating fruit at the end of the day.

Being from a traditional Asian background, the way “one looks and acts tends to be judged a lot more”, he said.

“Because I’d got bulimia as a get out, I’d binge eat. I might eat six or seven crisp packets at one sitting. I’d find comfort and my escapism via food.”

Suffering bullying at school, Dr Patel said that there was “pressure as a teenager to look cool”. He said that “the thinner I got, the more attractive I felt”. Bulimia became the “solution”, he added.

As he lost weight, he began receiving compliments which would “feed the beast”.

At least 1.5 million people in the UK have an eating disorder, experts estimate, with 25% being male. Bulimia nervosa is a condition that occurs most commonly in adolescent females, though it can appear in just about any patient. It is characterised by indulgence in binge-eating, and inappropriate compensatory behaviours to prevent weight gain.

Dr Patel said after he went to university he stopped, “I wasn’t able to find the safe space to have the… episodes, I didn’t want the truth to come out.”

From around the age of 24, he received cognitive behavioural therapy and in recent years has had psychotherapy.

“I was diagnosed with gut issues in 2014 and that’s when I started exploring the link between gut health and depression. As my diet became healthier so did my mind.”

A business director as well as a clinician, he now comes up with gut-healthy-recipes that are shared on his Dish Dash Deets website, set up during the COVID pandemic, where he also keeps a blog.

Included in his recipes are his top foods to combat depression and low mood, such as bananas, berries, beans and lentils.

He said to anyone that is in a similar position to his, “find a safe person to talk to”, who would not judge, adding: “Don’t feel any shame. You’re human.”

“The more that you rely on it, you use it as your way of escaping, the more it becomes your norm,” he said.

He also currently does live cook-alongs on Instagram with invited celebrities and chefs.

“Food is still my escapism. Now I enjoy being in the kitchen and making things that will serve my needs, not make things worse.”

Scientists Find How Enriched Environments Boost Brains

On By ModernMedia

A recent study in Frontiers in Molecular Neuroscience has shown how environmental enrichment ‘opens up’ chromosomes through the action of ‘master switches’.

Environmental enrichment, that is, making stimulating and interesting surroundings, is often used in zoos, laboratories, and farms to stimulate animals and increase their wellbeing.

Stimulating environments are better for mental health and cognition because they boost the growth and function of neurons and their connections, the glia cells that support and feed neurons, and blood vessels within the brain. But what are the deeper molecular mechanisms that first set in motion these large changes in neurophysiology? 

The study investigators utilised a large molecular toolbox to map how environmental enrichment leads to changes in the 3D organisation of chromosomes in neurons and glia cells of the mouse brain, which change the activation of some genes within the genome. 

They show that genes which in humans are important for cognitive mental health are particularly affected, possibly leading to new treatments.

Chromosome ‘opens up’ with enrichment

“Here we show for the first time, with large-scale data from many state-of-the-art methods, that young adolescent mice that grew up in an extra stimulating environment have highly specific ‘epigenetic’ changes—that is, molecular changes other than in DNA sequence—to the chromosomes within the cells of the brain cortex,” said corresponding author Dr Sergio Espeso-Gil from the Centre for Genomic Regulation in Barcelona, Spain.

He continued, “These increase the local ‘openness’ and ‘loopiness’ of the chromosomes, especially around DNA stretches called enhancers and insulators, which then fine-tune more ‘downstream’ genes. This happens not only in neurons but also in the supportive glia cells, too often ignored in studies about learning.”

The team raised mice for the first month after birth in social groups inside housing with Lego blocks, ladders, balls, and tunnels that were frequently changed and moved around. As a control, other mice were raised in smaller groups inside standard housing. The researchers then used a variety of tools to pick up molecular changes in neurons and glia cells within the brain cortex. These included alterations in the 3D structure of chromosomes, particularly the local “chromatin accessibility” (openness) and “chromatin interactions” (where distant genes are brought together through loops, to coordinate activity). Chromatins are the proteins which make up chromosomes, carrying DNA and the proteins to package them.

Epigenetic ‘master’ switches

They show that two ‘master’ switches operational after environmental enrichment increase chromatin interactions and another increases chromatin availability, important for the pyramidal neurons involved in cognition. A third works on a key chromosomal protein histone H3, activating nearby genes as a result.

These switches mainly occur around genomic regions that contain enhancers, regulatory DNA that (when bound to proteins called transcription factors) can activate neighboring genes. Also affected were genomic regions with insulators, regulatory DNA that can override the gene-activating effect of neighboring enhancers.

The team concluded that growing up in an enriched environment causes highly local and specific epigenetic changes in neurons and glia cells. These then mostly increase the activity of a few genes within the genome.

Mental health in humans

“Our results show that many of the genes involved are known to play a role in the growth and differentiation of neurons, the development of blood vessels, the formation and patterning of new synaptic connections on neurons, and molecular pathways implicated in memory and learning in mice,” said Dr Espeso-Gil.

“And when we look for parallel regions in the human genome, we find many regions that are statistically associated with differences in complex traits such as insomnia, schizophrenia, and Alzheimer’s in humans, which means that our study could inform future research on these disorders. This points to the potential of environmental enrichment in therapies for mental health. Our research could also help to guide future research on chromatin interactions and the poorly known importance of glial cells for cognitive mental health.”

Distraction a Big Problem in Teletherapy Sessions

On By ModernMedia

A small survey has found that although therapists appear to prefer virtual sessions over in-person meetings, a significant proportion admit to being distracted while delivering care.

A third of respondents admitted to providing lower-quality care to clients during online sessions. Overall, 39% admitted to checking emails and social media while providing virtual care.

These were the results of a survey of 600 therapists conducted and published by OnlineTherapy.com, a virtual directory for teletherapists and counselors. It’s also an affiliate of the controversial app BetterHelp, stating on their website that the company “may receive compensation from BetterHelp if you purchase products or services through the links provided.”

Online care is generally well received by therapists: nearly half said they prefer virtual sessions over in-person meetings. They appreciated many advantages of virtual therapy, such as working from home which allows therapists to keep a flexible schedule and increases their availability. Video sessions also provide therapists with a uniquely intimate look into their clients’ daily lives, making assessing their mental health easier.

However, teletherapy has introduced its own challenges. Besides the struggle to remain for therapists to stay focused themselves, 56% of those surveyed said their clients are more easily distracted during virtual sessions, and 48% reported technological issues as a major impediment to their practice.

Peter Yellowlees, MD, of UC Davis Health in Sacramento, California, noted with concern and confusion that 16% of therapists reported substance use before or during their sessions.

“There are all sorts of people in this world who call themselves therapists, most of whom have very reasonable training, but quite a number don’t,” Dr Yellowlees told MedPage Today, expressing serious doubts about whether these rates of social media distraction and substance use during virtual sessions would ring true for mental health clinicians with PhDs and MDs.

According to a spokesperson from OnlineTherapy.com, the survey only asked if respondents were currently practicing mental health professionals and did not ask for their credentials or certifications.

The results of the survey did, however, echo Dr Yellowlees’s own concerns of mental health problems on the rise of among therapists in general. The vast majority (90%) said that during the last year they suffered mental health issues, including anxiety disorders (50%) and depressive disorder (48%). This would likely impact the level of care that a therapist able to provide to their clients.

A further concern is that 17% of respondents reported seriously considered suicide since the start of the pandemic.

But  Dr Yellowlees also sees teletherapy as a way for therapists to start getting the help that they need, rather than simply treating themselves in fear of stigma or possible repercussions for their licences.

“It’s undoubtedly helped significantly,” Dr Yellowlees said. “We know that certain teletherapies are actually good for the mental health of providers, as well as the patients.”

Older People That Feel Younger Live Longer

On By ModernMedia

A new study has found that older people who feel younger are generally more healthy. Such people have greater sense of well-being, better cognitive functioning, less inflammation, lower risk of hospitalisation and even live longer than their older-feeling peers. 

As Francis Bacon once said, “I will never be an old man. To me, old age is always 15 years older than I am.” Studies have shown that feeling younger than one’s chronological age has been known to have some health benefits. A twin study in Denmark showed that perceived age, correlated significantly with physical and cognitive functioning as well as with leucocyte telomere length — which prevents cells from becoming unable to divide.

Researchers from the German Centre of Gerontology analysed three years of data from 5039 participants in the German Ageing Survey, a longitudinal survey of German residents of age 40 and older. The survey had questions about the amount of perceived stress in peoples’ lives and their functional health—how well they could conduct daily activities such as dressing and walking. Participants also indicated their subjective age by answering the question, “How old do you feel?”

Participants with more reported stress tended to have a more rapid decline in functional health over three years, and that association between stress and functional health decline was stronger for chronologically older participants.

Among people who felt younger than their chronological age, there was a weaker association between stress and functional health decline. This protective effect was strongest among the oldest participants.

“Generally, we know that functional health declines with advancing age, but we also know that these age-related functional health trajectories are remarkably varied. As a result, some individuals enter old age and very old age with quite good and intact health resources, whereas others experience a pronounced decline in functional health, which might even result in need for long-term care,” said lead author Markus Wettstein, PhD, who is now at University of Heidelberg. “Our findings support the role of stress as a risk factor for functional health decline, particularly among older individuals, as well as the health-supporting and stress-buffering role of a younger subjective age.”

The researchers said their findings suggest that helping older people feel younger could mitigate the negative effects stress and improving health—though further study is needed to help determine what kind of interventions would work best. Dr Wettstein gave examples of such efforts, such as messaging campaigns to counteract ageism and negative age stereotypes and to promote ageing in a positive light could help people feel younger. More general stress-reduction interventions and stress management training could also prevent functional health loss among older adults.

Dr Wettstein said that there needs to be further studies to find the ideal gap between subjective and chronological age, as previous research has suggested that, up to a point, it’s helpful to feel younger, but those benefits decrease as the gap between subjective and chronological age increases. “Feeling younger to some extent might be adaptive for functional health outcomes, whereas ‘feeling too young’ might be less adaptive or even maladaptive,” he said.

Patient Awake for 13 Minutes During Surgery

On By ModernMedia

A patient in the US was awake for 13 minutes of his surgery because apparently his anaesthetic was never turned on.

In mid-2020 the patient, Matthew Caswell went into Progress West Hospital in O’Fallon, Missouri, for hernia repair and removal of a lipoma on the back of his neck.

However, he soon became aware that something was amiss.

“I knew I was in trouble when I felt the cold iodine hit my belly and they were scrubbing me off. At any second I was waiting to go out, but all of a sudden I just got stabbed in my stomach,” Caswell told local TV station KCTV.

Caswell’s lawyer Kenneth Vuylsteke told MedPage Today that a paralytic agent had already been given to his client, and then the mask was put on to receive sevoflurane for general anaesthesia, but the flow of the gas was never started.

Caswell able to feel pain and hear operating room conversation for 13 minutes, he told KCTV.

During this, his vital signs surged, said Vuylsteke. Records shared with MedPage Today show a baseline heart rate in the 65 to 70 range, which skyrocketed to 115 beats per minute within a few minutes of the first incision.

After the first incision, Caswell’s blood pressure also shot up, from a baseline of 113/73 mm Hg to 158/113 mm Hg — severe hypertension.

Vuylsteke noted that hat should have been ample warning that something was likely wrong with the anaesthetic.

What he gathered so far is that Caswell was brought into the operating room and given the paralytic agent. The anaesthesiologist or the nurse anesthetist put the anaesthetic mask on him, but then the surgeon requested to see the lipoma before starting.

Caswell was turned over so the surgeon could see the lipoma. He was then put onto his back again, and the mask was put back on, but the sevoflurane was never turned on, Vuylsteke said.

A “Significant Event Note” is in hospital records that acknowledges that a “review of the anesthetic record demonstrates a delay in initiating inhalational anesthetic after induction of anesthesia.”

The note indicates that Caswell and his mother were “immediately informed regarding the delay in initiating the inhaled anesthetic agent until after the start of the surgical procedure.” The hospital “provided emotional support and discussed our intention to ensure his pain and anxiety over the event were well controlled in the immediate term.” The hospital also recommended a psychology consult for which they would cover the cost.

Caswell charges that he’s suffering from post-traumatic stress disorder and panic attacks because of the experience.

He’s suing the anaesthesiologist, the nurse anaesthetist Kathleen and also their employer, Washington University in St Louis.

“I would have rather died on that table,” he told KCTV.

Is PTSD Underdiagnosed or Overdiagnosed?

On By ModernMedia
Photo by Alex Green from Pexels

In an article published in the BMJ, experts debated as to whether diagnoses of post-traumatic stress disorder (PTSD) are surging in Western society due to real trauma, or whether it is simply being overdiagnosed. 

Some clinicians are concerned that diagnoses of PTSD have increased throughout Western society since the late 1980s.

PTSD is a serious and uncommon condition resulting from severe trauma, but is has come to mean an umbrella term encompassing other disorders and normal reactions to stress, argued John Tully at the University of Nottingham and Dinesh Bhugra at King’s College London’s Institute for Psychiatry, Psychology & Neuroscience (IoPPN).

Estimates of lifetime population prevalence are now around 7% in the US (26 million cases) and at 5% in other high income countries. In the UK, PTSD is estimated to be in 1 in 13 youths and in mothers after 4% of all births.

In military settings, there may be an underdiagnosis of PTSD, they acknowledged, as well as in the developing world due to limited psychiatric resources. 
But in other settings, they argue that PTSD is often conflated with normal responses to difficult situations, which has led to increased pressure on services to make this diagnosis. 

“The conflation of stress with trauma—and of trauma with PTSD—has become rife. This is the most convincing explanation for overdiagnosis,” they wrote.

This “concept creep” they argue, may also involve “compensation culture” and vested interests of the “trauma industry” as factors, they said. Am alternative explanation could be that psychiatry and society have become more accepting of trauma, and so give more leeway to diagnosis and treatment.

At a public health level however, they believe this approach is problematic as, “resources are finite, and a line must be drawn somewhere as to what level of symptoms meets criteria.”

PTSD misdiagnosis also risks other more common conditions, such as depression, anxiety disorder, and personality disorders, not being appropriately treated, while trivialising PTSD risks the medicalisation of everyday life, devaluing resilience and protective social factors, they warn.

“On this basis, we must reclaim the diagnosis of PTSD for what it is—a profound and severe response to catastrophic events—and not a spectrum of reactions to trauma or everyday life,” they conclude.

However Stephanie Lewis, Sarah Markham and Gerard Drennan at King’s IoPPN and the South London and Maudsley NHS Foundation Trust, contend that there is compelling evidence showing that PTSD is much more commonly underdiagnosed, which has concerning implications.

They say that PTSD has clear guidelines for diagnosis, and there is no evidence to suggest that it is being overdiagnosed – and rather the opposite.

“Large epidemiological studies representative of the population have found that less than half of adults and two fifths of young people who meet criteria for PTSD have sought help from any health professional,” they wrote.

“These findings fit with our professional experience that people with PTSD often find it difficult to seek help—for example, because of avoidance symptoms, concerns about stigma, or fear that there may be no effective treatment,” they write.

Additionally, only a fraction of people with PTSD who access health services receive a diagnosis, they added.

They warned that underdiagnosis is concerning because, compared to those without PTSD adults who meet the criteria are over six times more likely to attempt suicide, and 10 times for young people with PTSD. However, treatment can be effective.

They argued that underdiagnosis to PTSD should be reduced, and access increased to service for diagnosis and treatment.

“Prioritising these actions now may prove particularly timely because the COVID-19 pandemic may have exacerbated the underdiagnosis of PTSD,” they concluded.

Loneliness in Middle-aged Men Tied to Cancer Risk

On By ModernMedia

A recent study by the University of Eastern Finland shows that loneliness among middle-aged men is associated with an increased risk of cancer.

Cancer is the second leading cause of death around the world, and in high-income countries it has become the main cause. Recent scientific evidence demonstrates that stress plays a positive role in cancer initiation, progression and cancer metastasis, as well as a negative role for anti-tumor immune function and therapy response.

“It has been estimated, on the basis of studies carried out in recent years, that loneliness could be as significant a health risk as smoking or overweight. Our findings support the idea that attention should be paid to this issue,” said project researcher Siiri-Liisi Kraav from the University of Eastern Finland.

The study was launched in the 1980s with middle-aged men from eastern Finland participating. To avoid reverse causality, individuals who already had a cancer diagnosis or received a cancer diagnosis within two years after the baseline data collection were excluded from the analysis. The  2570 eligible participants had their health and mortality monitored on the basis of register data through to the present. Follow-up lasted an average of 20.44 years, and the average age of cancer diagnosis was 69.96 years.
Factors accounted for included age, socio-economic status, lifestyle, sleep quality, depression symptoms, body mass index, heart disease and other risk factors.

During the follow-up, 649 men (25% of participants) developed cancer, and 283 men (11%) died of cancer. Loneliness was associated with a roughlt 10% increased cancer risk. In addition, cancer mortality was higher in cancer patients who were unmarried, widowed or divorced at baseline.
Based on these results, the researchers recommended that consideration of loneliness and social relationships should be an important part of comprehensive health care and disease prevention. The findings were published in Psychiatry Research.

“Awareness of the health effects of loneliness is constantly increasing. Therefore, it is important to examine, in more detail, the mechanisms by which loneliness causes adverse health effects. This information would enable us to better alleviate loneliness and the harm caused by it, as well as to find optimal ways to target preventive measures,” concluded Kraav.

Hiking Prescribed for Elderly Man Coping with Lockdown

On By ModernMedia

When Jim Snodgrass, 84, was expecting to receive medication to treat his anxiety, he instead was simply given the phone number for the Ramblers, a UK-based society of nature walkers and hikers.

Dr Victor Jack said that he recognised that Jim needed “social connection” and not medication. Hiking itself also has a number of proven physical and psychological health benefits. Some may be immediate, such as decreased blood pressure, decreased stress levels, enhanced immune system functioning, and restored attention, or else occur over time, such as weight loss, decreased depression, and overall wellness.

During the first COVID lockdown in March 2020, Jim was on his own since his wife Sheila died six years previously, said he suffered a breakdown.

The grandfather-of-two said: “I was not feeling good as I was bothered with my nerves so I called the doctor and that’s when I burst into tears on the phone to the receptionist.

“She was so nice to me and got the doctor to call me. I was surprised when he didn’t give me any pills and instead gave me the number for the Ramblers.”

During lockdown doctors could give exemptions to people who lived on their own to meet one other person outside. Then last summer people were allowed to meet in groups to walk.

Presently in the UK, groups of 15 people are allowed to meet outside.

He said: “The Ramblers saved me during the last year of lockdowns. I don’t know where I would be without them with my nerves. Within two miles of walking I’m a different person. Dr Jack is an amazing man as he has saved me from my nerves in the lockdowns with this idea of his.”

Jim has walked 6.4 to 8 kilometres a day in the last year.

He said: “I even went out when the roads were icy and always stayed within a five mile radius of South Queensferry during the lockdowns. I hope my story helps someone else who is feeling bad so they know to join their local Ramblers group too.”

Dr Jack, of South Queensferry Medical Practice, told BBC Scotland his own experience with stress was used to inform Jim’s treatment.

“When Jim told me he liked walking but that he had been walking on his own I was aware that he was actually quite socially isolated as his wife had died,” Dr Jack explained. “He was benefitting from the physical part of walking but not the social side. A few years ago I joined a running club and found it very helpful for stress. This has made me recognise that any sports club has a benefit particularly through the social connection it provides.”

Dr Jack said he had seen numerous patients experiencing mental health issues during the lockdown, especially in those working from home.

Brendan Paddy, director of Ramblers Scotland, said: “Jim is truly an inspiration to us all. It’s amazing to see how he’s improved his health and happiness by getting active with his local South Queensferry Ramblers group.

“Clearly lockdown has been a hugely challenging time, yet we know that many more people like Jim are discovering the revitalising power of walking – with booming numbers enjoying Scotland’s outdoors. I’d urge anyone who’d like a bit more adventure, friendship and fresh air in their lives, to give the Ramblers a go.”

Dietary Supplement Treats Schizophrenia in Mouse Model

On By ModernMedia

A study has found that a simple dietary supplement reduces behavioral symptoms in mice with a genetic mutation that causes schizophrenia. 

Schizophrenia is estimated to affect about 1 in 100 people globally and is one of the top 15 leading causes of disability worldwide.

The study examined the role of betaine in schizophrenia, as it is known to be reduced in the brains of schizophrenia patients. Betaine, often associated with sweetness or umami flavours, was first isolated from sugar beets and is acquired through the diet and also produced in the body. Betaine supplements are already used clinically to treat the metabolic disease homocystinuria.

“I don’t encourage anyone to take betaine for no reason, if a doctor has not recommended it. But, we know this drug is already used clinically, so repurposing it to treat schizophrenia should be safe,” said study leader Professor Nobutaka Hirokawa, MD, PhD, from the University of Tokyo Graduate School of Medicine.
“There are treatments for schizophrenia, but they have side effects and unfortunately there is still no effective drug for patients to take that we can explain biochemically why it works,” Prof Hirokawa added.

Genetic studies have found possible links between schizophrenia and variations in the kinesin family 3b (kif3b) gene as well as another gene involved in the body’s production of betaine. The researchers categorised all 45 members of the kinesin superfamily of genes in mammals, most of which encode motor proteins that move materials throughout the cell. Together with another protein kinesin superfamily, the KIF3B protein transports cargo throughout a neuron, travelling up and down the cell’s skeleton.

The researchers mice used to model schizophrenia which had only one functional copy of the kif3b gene. These mice have different behaviours to normal mice such as avoiding social interactions and being less startled by a sound test. The Kif3b mutant mice that were raised on a diet with triple the normal amount of betaine had normal behaviour.

To work out why betaine had this effect on mice, researchers grew nerve cells with the kif3b mutation in the laboratory and added fluorescent labels so they could watch the development of cellular skeleton.

Kif3b mutant neurons grown in the lab have an unusual, overly branched structure with too many dendrites, unlike the normal tree-like shape of healthy neurons. Similar overly branched neurons are also seen in brain samples donated by people with schizophrenia, regardless of any treatments or medications they took while alive.

During healthy neuron development, the cell’s main body fills with a skeleton component called tubulin. Meanwhile, the cell’s front growth cone builds outwards in a spiky, erratic dance due to the movements of another skeleton component known as filamentous actin. In kif3b mutants, this dancing movement, which experts refer to as lamellipodial dynamics, is reduced and the distinction between tubulin and actin is blurred.

Chemical analyses of the brains of kif3b mutant mice and human schizophrenia patients reveal significant chemical damage to CRMP2, a protein which helps assemble actin. This damage causes the proteins to clump together. However, betaine is known to prevent the kind of chemical damage, carbonyl stress, responsible for CRMP2 dysfunction.

“In postmortem brains of schizophrenia patients, CRMP2 is the protein in the brain with the most carbonyl stress. Betaine likely eliminates the carbonyl stress portion of the schizophrenia equation,” said Hirokawa.

It appears that by shielding CRMP2 from damage, betaine treatment allows kif3b mutant neurons to build normal structures, allowing the remaining functional KIF3B protein can shuttle cargo around the cell. Other in vitro experiments showed that KIF3B and CRMP2 can bind together, but their exact relationship remains unclear.

“We know that the amount of betaine decreases in schizophrenia patients’ brains, so this study strongly suggests betaine could be therapeutic for at least some kinds of schizophrenia,” said Hirokawa.

‘Toad Venom’ Drug for Treatment-Resistant Depression

On By ModernMedia

Dublin-based biotech company GH Research is developing an inhaled version of the psychedelic known as ‘toad venom’ be used for treatment-resistant depression.

On Monday the company announced that it had closed a Series B round to help advance its lead program, an inhalant called GH001, for psychiatric and neurological disorders. GH is beginning with treatment-resistant depression, but has two more indications which are not yet disclosed.

Treatment-resistant depression occurs when little to no success is seen from antidepressants or psychotherapy for patients with major depressive disorder. Though symptoms can be mild, they can also be severe and major depressive disorder can be life threatening.
Colloquially referred to as toad venom, it is commonly referred to as 5-MeO-DMT (5-Methoxy-N, N-dimethyltryptamine is the official name). due to its presence in a certain toad species native to parts of North America. It can be extracted from plants, or produced artificially. The plant version used as an entheogen, a hallucinogenic drug, in some parts of Central and South America.
In the mid-2010s, the drug skyrocketed in popularity among those trying to achieve the ‘ego death’ phenomenon, a situation in which it is believed the part of the brain responsible for one’s sense of self shuts down temporarily. Users on Reddit and YouTube, engaged in an “arms race” to boast about their experiences, according to a VICE report. It is so potent that it is not considered ‘recreational’ as its effects are so strong that it needs to be taken in a safe environment. The drug is treated as a Schedule 1 narcotic in the US, with severe penalties for possession. However, there is strong interest in using it to treat anxiety and depression, with initial research showing effects similar to psilocybin, a mushroom-derived hallucinogen, but with a shorter delay in reaping the benefit.

Recently, investor interest has mounted in psychedelics-focused biotechs, most notably surrounding the Peter Thiel-backed ATAI Life Sciences, a company that uses a unique business model bringing portfolio companies under one umbrella to developing therapeutics for various mental health disorders.

GH is much more narrowly focused on its 5-MeO-DMT work, reporting that GH001 has completed a Phase I study in healthy volunteers. GH001 was shown to be well-tolerated, and it’s now in a Phase I/II trial in patients with treatment-resistant depression.

The biotech company is also working on an injectable formulation of 5-MeO-DMT, which they are calling GH002 and are also keeping quiet about its potential indications.
