Psychedelics – how modern neuroscience research is leading to new treatments for brain disorders

Psychedelic therapies have the potential to vastly improve the treatment of mental health disorders such as depression. The Imperial Centre for Psychedelic Research is paving the way in exploring these innovate treatments using psilocybin – the active ingredient in magic mushrooms. Here, Professor David Nutt from the Department of Brain Sciences discusses. 

When most people think of psychedelics, the first thing that comes to mind is LSD-inspired Flower Power during the 1967 Summer of Love in the USA, with its associated revolution in art and music. This explosion of use was seen to be fuelling the protests against the war in Vietnam and so rapidly led to LSD and related psychedelics such as psilocybin (the active ingredient in magic mushroom) being banned, first in the USA and then later globally. This ban still exists today and has effectively censored research for over 50 years. The ban is very unfortunate as prior to this there were hundreds of studies that showed psychedelics were effective treatments for a range of mental illnesses as well as some other brain disorders. Millions of patients may therefore been denied access to potentially life-saving treatments.

This situation is beginning to change with several universities setting up psychedelic research groups including the Centre for Psychedelic Research at Imperial, which was the first and is now five years old. The impetus to these new research centres is twofold. First, today we have much more powerful neuroimaging methods to examine the impact of psychedelics on the brain and second, these neuroimaging studies have revealed possible mechanisms underpinning the therapeutic activity of psychedelic drugs, so encouraging more clinical research. This research has revealed remarkable efficacy in a number of patients who have not responded to prior conventional treatments and may be the start of a whole new phase of novel therapies for mental illnesses.

‘It can make a massive difference’: How to be a trans ally

Every student deserves to be treated with dignity, respect and fairness at University. Unfortunately, this isn’t always the case for transgender students. So, how can you step up and be an authentic ally for the transgender student community? Medical student, Elliot, discusses all things allyship.

Treating people with respect and dignity is the utmost priority for many people at university, however meeting someone who is transgender can be confusing and new for a lot of people. With ever changing laws, media output and opinion, it’s easy to feel overwhelmed and swept up when trying to care about those around you. I have compiled the some tips for supporting the trans (non-cis) people in your life, so that you know where to start.

From Britpop to breakthroughs: Reflecting on 30 years of HIV testing and treatment

Born on what would eventually be recognized as World AIDS Day in the 1970s, Dr Mike Emerson, now affiliated with the National Heart and Lung Institute, relocated to vibrant London during the early 1990s amidst the fervour of the Britpop era. In the backdrop of Blur and Pulp melodies, 1990s London faced the AIDS crisis. Three decades later, he is at the helm of a team investigating cardiovascular ailments in people with HIV. In this piece, Dr Emerson reflects on the advancements in HIV diagnosis and therapy, and reiterates the ongoing importance of  National HIV Testing Week. 

I was born on what was to become World AIDS day way back in the 1970s, and moved to the big smoke in the early 90s. London was exploding with Britpop excitement, and in the absence of mobile tech, we went out every night to the sounds of Blur and Pulp. 90s London was also the epicentre of the UK’s bit of the global AIDS crisis. People in their early 20s, as I was, were dying (of ignorance the government told us). I quickly learnt not to hold birthday celebrations in Soho; celebrating and mourning young friends and sons don’t mix well. Exactly 30 years later, I lead a team investigating cardiovascular disease as people live with HIV for decades and succumb to the diseases of old age. This week is HIV testing week, so it’s a good time to reflect on how far we have come and remind ourselves of the importance of HIV testing. 

Back in 1981, a couple of obscure articles noted incidences of fatal pneumonia and rare skin cancers in otherwise healthy young American men. Oddly, these men were all gay. Within months, there was an explosion of terrifying fatal illness amongst the gay communities of New York, San Francisco and, not far behind, London. People became infected with HIV following blood transfusions, and babies were born with the condition and died. When HIV tests became available, the prospect of one was terrifying, involving a week-long wait for results and a recommendation to take a friend when results were due to be delivered.

Queer in the field: The unique challenges of LGBTQIA+ scientists conducting international research

LGBTQIA+ scientists can face nuanced challenges when travelling abroad to conduct research. Bethan Cracknell Daniels, Research Postgraduate in the School of Public Health, reflects on her time in Ghana supporting infectious disease control, and how the  LGBTQIA+  International Support Group are advocating for a more inclusive global scientific community.

While applying for my PhD in Infectious Disease Modelling at Imperial in 2019, I wanted to gain hands-on experience in infectious disease control. At the time, I was an undergraduate student studying Immunology at the University of Manchester. I applied for an internship with a laboratory on the edge of Accra, Ghana, providing infectious disease diagnosis to a local hospital. I was excited to be accepted and immediately went about booking flights and organising my visa.

It was only a week before my flight that I learned Ghana criminalises homosexuality, with physical homophobic attacks against LGBTQIA+ individuals being common. As a queer woman with a same-sex partner, I was nervous. Living in Manchester, with its famous gay village, I was very open about my sexuality and thought nothing of walking down the street holding hands with my girlfriend. Unsure of how to navigate being gay in Ghana, I eventually decided to tell people I didn’t have a partner, effectively returning myself to the closet.

Unravelling the mystery of smaller lungs in low- and middle-income countries

Andre Amaral

In low- and middle-income countries (LMICs), a notable number of individuals have smaller lungs for their sex, age, and height, especially in South and East Asia, as well as sub-Saharan Africa. The key question: Why does this pattern persist in these regions?

This phenomenon extends beyond physiological concerns, and as indicated by recent studies, reveals a troubling link between smaller lungs and heightened risks of suffering from heart disease and diabetes. Dr André Amaral, an epidemiologist at the National Heart and Lung Institute (NHLI), explores this phenomenon.

The BOLD study

Chronic lung diseases affect millions of people of all ages worldwide. Approximately 20 years ago, the Burden of Obstructive Lung Disease (BOLD) study was set up by Imperial College London to find out more about the prevalence and determinants of chronic obstructive pulmonary disease (COPD), which back then, was already considered a leading cause of disability and death.

The BOLD study was conducted in 41 sites across Africa, Asia, Australia, Europe, the Caribbean and North America, and recruited more than 30,000 adults aged 40 years and over. The large coverage of world regions, and ethnic groups, as well as the large number of participants, all answering the same questions and undergoing the same measurements in a standardised manner, makes the BOLD study unique. Participants in this study provided information on several characteristics of their life. This included whether they had been diagnosed with lung disease, a heart disease, or diabetes, whether they smoke or ever smoked, their weight and height, and their highest level of education. The level of their lung function was measured through a medical test called spirometry, which measures how much air a person can breathe out in one forced breath.

Nurturing hope: Understanding Dilated Cardiomyopathy and transforming heart failure prospects

As the leading cause of heart failure in young individuals, dilated cardiomyopathy presents a unique set of challenges and implications. It is an intrinsic heart muscle disease that is the most common reason for needing a heart transplant. The origins of this condition are diverse, spanning genetic predispositions, external triggers that subject the heart to undue stress, or often, a combination of both. Dr Brian Halliday, a Clinical Senior Lecturer and British Heart Foundation Intermediate Fellow at the National Heart and Lung Institute sheds light on this disease and how medical advancements have enabled some patients to go into remission.

Heart failure can be a devastating diagnosis. The prognosis has been shown to be worse than many of the most common cancers. The words themselves often create a sense of doom for patients.

Dilated cardiomyopathy is the most common cause of heart failure in young people and the most common reason to need a heart transplant. It is an intrinsic heart muscle problem where the heart becomes baggy and weak. It may be due to genetic susceptibility, extrinsic acquired triggers that put the heart under stress, or a combination of the two. At the National Heart and Lung Institute, we have a particular interest in dilated cardiomyopathy.

What happens when industrial technology meets nature? A French invention of the 1830s, the compressed air bath capitalised on the allure of ‘pure countryside air’ to treat a range of respiratory problems. Dr Jennifer Wallis, Medical Humanities Teaching Fellow, explores the fascinating history of these baths and their therapeutic uses in mid-Victorian Britain.

During the summer holiday season, many of us will have taken a break to recharge our batteries. Whether it’s gazing out over a clear blue sea or hiking through a forest, connecting with nature is often a key component of our holidays.

Tourists in the 19th century sought a similar experience. They yearned to escape the crowded city or the routines of home to immerse themselves in a new environment. The era is most associated with the seaside resort, which grew in popularity as the railway network expanded. But many Britons were also choosing to follow in the footsteps of their eighteenth-century ancestors by visiting spa towns like Malvern. Spa towns were renowned for their health benefits, from the freshness of the air to the energising effect of the mineral waters. Hotels and resorts sprung up in spa towns to cater for the health-seeking hordes.

One such resort was the Ben Rhydding Hydropathic Establishment in Ilkley, Yorkshire. It cashed in on a contemporary interest in hydropathy, a treatment regime based on baths and showers. Ben Rhydding offered its visitors a variety of activities to supplement these treatments: bowling greens, dances, and guided walks of local beauty spots. It also offered a rather unusual experience for the health-seeking tourist, one that used air rather than water: a compressed air bath.

Team Science Leads the Way – But Hero Science Still Looms Large

Artwork by Mengmeng Tu, MSc Science Communication student

This festive period, Three Wise Women from the Faculty of Medicine will be giving us the gift of wisdom.

When it comes to tackling the world’s biggest health challenges, teamwork makes the dream work for Professor Wiebke Arlt, Director of the MRC Laboratory of Medical Sciences (LMS). Here, she discusses why it’s time that contemporary science shifted from a hero science to a team science approach – one based on productive collaboration rather than wasteful competition.

Going it alone is often glorified as the breakthrough way of achieving major milestones. However, if you look closely, most of these are achieved in a team effort and not by single individuals. Our perception of heroes rather than teams is often driven by the narrative and not the facts: when I was a child, I learnt that Edmund Hillary was the first to climb the highest mountain in the world, Mount Everest. Now I know that Hillary achieved this feat together with the Nepalese mountaineer Tenzing Norgay. Reading up on it, I discovered that they didn’t walk up the mountain on their own, but they were part of a large expedition team that worked together to achieve the goal. Hillary and Norgay were the second pair to be deployed as part of a systematic team approach to conquering the mountain.

Embracing Ubuntu in Higher Education: The Power of Togetherness

Artwork by Mengmeng Tu, MSc Science Communication student

This festive period, Three Wise Women from the Faculty of Medicine will be giving us the gift of wisdom.

Ubuntu (ooh-bun-too) is a concept, a philosophy, a way of living in Africa. It highlights the interconnectedness of all individuals and encourages people to recognise their shared humanity. Here, Dr Sungano Chigogora, Senior Teaching Fellow in Epidemiology in the School of Public Health, explores the spirit of Ubuntu and why it should be at the heart of teaching and learning.

In Central and Southern Africa, Bantu means ‘people’ or ‘humanity’ to hundreds of millions of individuals whose languages have common ethnolinguistic roots. To them, Ubuntu is a core characteristic of humanity that extends beyond the individual, and recognises not only their humanity, but how they belong to a deep community in which they can participate, share, and grow. As observed by the late Archbishop Desmond Tutu, “Ubuntu is very difficult to render into a Western language. It speaks to the very essence of being human. … to give high praise to someone we say … ‘he or she has Ubuntu’. This means that they are generous, hospitable, friendly, caring, and compassionate” (Tutu, 1999).

Closing the Gender Health Gap: A Call for Sex and Gender Equity in Biomedical Research Policies

When it comes to healthcare, there are clear and stark inequalities between women and men. Marina Politis, Alice Witt, and Kate Womersley explain how, at its root, this gender health gap derives from a research and data gap, and how the MESSAGE project is working to improve accounting of sex and gender dimensions in medical research.

Everyone aspires to receive gold standard treatment when seeking medical care. What if, however, this standard, was only ever set out to be gold for one group of people? Much of our medical evidence base has been based on a male norm, with women underrepresented at all stages of the research pipeline. Subsequently, when a woman suffers an out-of-hospital cardiac arrest, she is less likely to receive bystander CPR than a man. Once in the hospital, she continues to be less likely to receive optimal care than her male counterpart.

The gender health gap in cardiovascular disease – poorer outcomes women experience due to the “male default” in health research and healthcare – is just one of many conditions for which there are disparities between women and men. From dementia to diabetes, and osteoporosis to obesity, sex and gender differences and similarities remain neglected in UK and international research.
