The human brain, a complex and mysterious organ, is one of the greatest frontiers of scientific research. Despite incredible advances in medicine, our understanding of the brain’s inner workings – its language of signals, its language of thought, and the location of memories – remains hazy. This lack of knowledge is particularly alarming given the fact that so many diseases are neurological or psychiatric in nature.
Despite this, funding for brain research lags far behind other fields such as cancer research: for example, NIH spending on cancer research from 2014 to 2022 exceeded $50 billion, while the amount allocated to the BRAIN Initiative during the same period was only $3 billion.
This discrepancy raises important questions about our research priorities and the future of neurological health.
As someone who has been researching epilepsy for over 10 years, getting research funding is a huge struggle and this is no exception. As CEO of The Brain Forum, a platform established to shine a spotlight on brain research in Switzerland, I have found that many researchers empathize with my experience.
The Complexity of Brain Research
One argument I’ve heard as a reason for the funding gap is the perceived complexity and difficulty of brain research. The brain’s intricate network of neurons and synapses, combined with the difficulty of accessing and studying living brain tissue, poses major scientific and technological challenges. Progress has been slow, and breakthroughs are less frequent compared to fields such as oncology, where advances in genomics and personalized medicine have led to more rapid therapeutic success.
The urgency of increasing funding can no longer be ignored: mental illnesses such as depression and anxiety are exacerbated by global challenges and the rapid societal changes we are witnessing due to the digital revolution.
There is also a persistent stigma attached to asking for help.
Therefore, in my view, increased public funding for brain research is essential. This includes increased support for large-scale efforts such as the BRAIN Initiative and the Human Brain Project. Governments can also encourage pharmaceutical companies to invest in CNS research through grants, tax credits, and public-private partnerships.
The challenge of misinformation
Additionally, the media can contribute by raising public awareness about the importance of brain research and avoiding misinformation about our understanding of the human brain, which in my view has a significant negative impact on funding for brain research.
When the public is exposed to misleading information, such as that reported in the mainstream media, they may develop false beliefs about advances in brain research. Furthermore, when policymakers and funding agencies are influenced by inaccurate portrayals, they may prioritize less effective approaches over legitimate ones.
This diverts important resources from credible scientific projects that could lead to important breakthroughs. There is a risk that funding opportunities will decrease if the public is misinformed. Public and private funding agencies may be reluctant to invest in brain research if they receive conflicting messages that could undermine scientific discoveries. This could spread confusion and dilute the impact of legitimate research. It could also be a distraction from having to counter false claims.
It may also be helpful for scientists and researchers to actively engage with the media to ensure accurate reporting by providing easy-to-understand summaries of research findings, participating in interviews, and offering expert opinion to guide journalistic stories. Similarly, collaborative efforts could include fact-checking efforts and the development of guidelines for reporting scientific research.
The importance of collaboration and long-term investment
It may also be helpful to foster interdisciplinary research that leverages advances in related fields such as artificial intelligence (AI), neuroimaging, and genetics. Joint efforts can accelerate breakthroughs in understanding and treating brain disorders.
When it comes to human brain research, it is also important to recognize that brain research is a long-term investment that we as a society must commit to, given that major advances may take time.
In addition to all of the above, we must also intensify our efforts to reduce the stigma associated with mental health and neurological disorders, so that more people will seek help and the spotlight will be on the true importance of mental health issues.
Finally, the human brain, despite being the source of our thoughts, emotions and identity, remains a largely unexplored territory. The alarming rise in brain-related diseases and the relatively low effectiveness of current treatments highlight the urgent need to increase investment in brain research.
By reallocating resources, encouraging private sector involvement, and raising public awareness, we can unlock the mysteries of the brain and contribute to the development of more effective treatments for neurological and psychiatric disorders. Investing in brain research is not only a scientific imperative, it is also a societal imperative. We must prioritize keeping our minds as healthy and vibrant as our bodies.
