TRR265 scientist Ann-Kathrin Stock is interviewed for a Deutschlandfunk programme on the topic of ‘Medicine or myth’ about alcohol hangovers. In the podcast, the experts explain how excessive alcohol consumption leads to a hangover and explore the question of whether sour drinks can actually help to relieve headaches, nausea and dizziness, or whether it is just a well-intentioned myth. They shed light on the scientific background, explain how the body reacts after excessive alcohol consumption and what really (doesn't) help against a hangover. If you want to know whether sour is the right solution or whether there are better alternatives, you shouldn't miss the latest episode of ‘Medicine or Myth’! HERE THE LINK

In a recent commentary published in  The Lancet Psychiatry , Bernd Lenz and Birgit Derntl, researchers from the German Center for Mental Health (BL and BD) and the CRC/TRR 265 (BL), underscore the critical need for sex-sensitive and gender-sensitive approaches in the treatment of mental disorders. Despite advancements in research and the endorsement of the Sex and Gender Equity in Research (SAGER) guidelines, the integration of these considerations into clinical practice remains limited. The authors call for a shift in how mental health care is conceptualized and delivered, advocating for the establishment and implantation of tailored strategies that recognize the unique vulnerabilities and resilience factors associated with different sexes and genders. This initiative aims to enhance patient outcomes and ensure that mental health services are inclusive and effective for all individuals.

In a recent expert review published in “Translational Psychiatry”, Giannone and colleagues delve into the intricate relationship between habitual and goal-directed behaviors in the context of alcohol use disorder (AUD). The study highlights the significant public health challenge posed by excessive alcohol consumption and its detrimental effects on life expectancy. Through a meta-analysis of rodent studies, the authors explore how chronic alcohol exposure alters neurobiological processes, leading to habitual responses that can overshadow goal-directed actions. They emphasize the importance of precise terminology in addiction research, distinguishing between habitual behaviors and compulsivity. This comprehensive analysis not only sheds light on the mechanisms underlying AUD but also calls for further research to develop effective interventions for those struggling with alcohol addiction.

We are happy to announce the publication on the TRR265 project by the entire ReCoDe Addiction Research Consortium in Addiction Biology. In this article, we summarize the goals of the consortium and explore the trajectories of losing and regaining control over drug consumption, offering valuable insights into the behavioral, cognitive, molecular, and neurobiological mechanisms underlying addiction. Through a holistic approach that combines innovative mobile health tools and cutting-edge research methodologies, we identified triggers and modifying factors that influence individuals' journeys from voluntary drug use to compulsive behavior. By integrating multi-omics data from biomaterials of our ReCoDe cohort, our researchers generated pathway- and gene-derived polygenic scores, providing a deeper understanding of the genetic and environmental factors contributing to addiction. Our consortium highlights the importance of an integrative multi-omics approach in addiction research, emphasizing the need to explore the intricate interplay between genetic makeup, environmental influences, and drug exposure. Our findings pave the way for the development of mechanism-based interventions tailored to individuals struggling with substance use disorders. This publication marks a significant milestone in the ReCoDe Consortium's mission to advance addiction research and develop innovative strategies for regaining control over drug intake. Stay informed about the latest developments from the ReCoDe Consortium as we continue to make strides in unraveling the complexities of addiction biology.

The US foundation Wellcome LEAP is funding a research project at the CIMH in which addictive disorders are treated with weak electrical currents on the scalp, among other things. It is estimated that 108 million people worldwide are addicted to alcohol, and almost 40 million have an addiction to illegal drugs. In 2019, 168,000 people worldwide died from alcohol abuse and it was a risk factor for a further 2.44 million deaths. Illicit drugs led to over 128,000 deaths in the same year. This underlines the urgent need for innovative approaches to addiction prevention and treatment. To help develop and introduce new technologies and methods, the US foundation Wellcome LEAP is supporting innovative research projects with a total of 50 million US dollars. A research project at the Central Institute of Mental Health (CIMH) under the direction of Prof. Dr. Sabine Vollstädt-Klein, head of the Neuroimaging of Addictive Behavior working group at the CIMH, and Dr. Sarah Gerhardt, research associate and Psychological Psychotherapist at the Clinic for Addictive Behavior and Addiction Medicine at the CIMH, is the only project in Germany to be funded by the foundation. Modulating neuronal activity in the brain In the project, patients with various addictive disorders are examined and additionally treated with transcranial direct current stimulation (tDCS) during their inpatient stay. This involves attaching electrodes to the scalp, which then emit weak electrical currents. The procedure has few side effects and aims to modulate neuronal activity in the brain. “In patients with addictive disorders, we hope that this modulation of the brain can better inhibit impulsive behavior, which beneficially contributes to abstinence. We are therefore investigating whether tDCS has a positive effect on this impulse inhibition and the success of the therapy and are also measuring brain wave patterns in order to understand how these effects come about,” explains Sabine Vollstädt-Klein. The procedure is already approved for depression, for example. One advantage is that tDCS is comparatively easy to use and can therefore also be used by patients independently at home. Wellcome LEAP is part of the foundation Wellcome Trust. Established in 2020 by the Wellcome Trust as a US non-profit charitable organization with initial funding of USD 300 million, the LEAP funding programs target complex human health challenges with the aim of promoting breakthrough science and technology solutions.

The American Research Society on Alcoholism is awarding this year's AREC Prize to Prof Rainer Spanagel for his outstanding contributions to ethical standards in preclinical and animal research. In the announcement by the Commettee it is said that Dr. Spanagel has been a trailblazer in preclinical addiction research, conducting over 10 meta-analyses to advance the field. Furthermore, his leadership in reducing animal use in research is exemplary; from creating an organ bank for genetically engineered mice to implementing in silico methods that minimize the need for animal testing. Most recently, Dr. Spanagel has launched the STRINGENCY framework, promoting best practice guidelines to enhance the reliability and impact of preclinical alcohol research. We celebrate Dr. Spanagel's remarkable achievements and anticipate the broader adoption of these higher ethical standards in animal research.

The discussion about the legalisation of cannabis from the age of 18 raises concerns among experts. Psychopharmacologist Prof Dr Rainer Spanagel in particular is concerned about the possible effects on young people. He warns of the risks of highly concentrated THC products and emphasises that the brains of 18-year-olds are not yet fully developed. Spanagel argues in favour of a higher age limit and criticises politicians for ignoring scientific findings. He fears that legalisation could send a fatal signal to young people and that young people could continue to resort to the black market.

In an interview, Professor Maximilian Pilhatsch summarises addiction medicine concerns and findings regarding cannabis legalisation. Pilhatsch warns of the effects of excessive cannabis use on IQ, as studies show that IQ can drop significantly due to prolonged use at a young age. He also emphasises that cannabis interferes with brain metabolism and can cause negative consequences such as drug-induced psychosis, depression and anxiety disorders. The legalisation of cannabis is viewed critically by Pilhatsch, as it changes society's overall attitude towards the drug and increases its acceptance and availability, which can lead to it being trivialised. He explains why he sees the legislator as being close to co-dependency. Pilhatsch warns of an increase in cannabis users and emphasises the dangers, especially for young people, whose brain maturation processes can be impaired by cannabis.
