Alzheimer’s is often called the “silent thief,” stealing memories long before symptoms appear. Lund alumnus and world-renowned researcher Oskar Hansson is determined to stop it in its tracks.

He rarely takes a long lunch. Natural yoghurt with blueberries and walnuts, nature’s own brain boosters, fuels his focus as he ticks off a lunch meeting on his calendar. Oskar Hansson is on a mission. His team has developed a simple blood test that can detect Alzheimer’s with high accuracy, even before symptoms appear. Already in use in clinics across the globe, it’s a quiet revolution in diagnostics.
Going to Boston
In about a year, he and his wife will begin packing up their lives in Lund to move to Boston, where he’ll join the pharmaceutical company Eli Lilly (or just Lilly). They are both excited about it! His new role: Vice President for Neurodegenerative Disease Early Phase Clinical and Imaging Development.
The title is a mouthful, but what it means is that he’ll be leading the early development of new treatments for degenerative brain diseases, guiding how they’re tested, tracked and refined in their earliest stages.
The reason behind the move is simple. To develop effective treatments, he needs the kind of specialised expertise and resources found within pharmaceutical companies. And he feels confident leaving his work in Lund in capable hands.
“Several promising leaders have emerged within our research group, well-equipped to take over and continue its development,” he says. “And I had reached my primary goal: to help create simple diagnostic tools that are set to revolutionise healthcare. My new ambition is to develop effective treatments for brain diseases, and that goal is far better supported within the pharmaceutical industry.”
Social life, humour and mitochondria

With a special interest in physics, math, quantum theory and the mysteries of relativity—alongside a growing curiosity for philosophy and biology—it was no surprise that after Swedish upper secondary graduation, Oskar eventually chose medical school in Lund. His passion for research was evident as he would seek opportunities to delve into even during summer breaks.

“Already during the first semester of medical school (autumn 1994), I began conducting research in the evenings, on weekends, and during summer holidays. I started with a project in neuroimmunology with the goal of finding treatments for brain cancer,” he shares.
Despite his intense focus, Oskar wasn’t all “lab coat”. He embraced student life, joining Lund’s “Toddy spex”, a theatrical Lund Medical School tradition blending satire, music, and academic parody. It’s the kind of thing that requires a good sense of humour and a willingness to not take yourself too seriously.
“It’s important to be able to laugh at yourself and move on when you’ve made a mistake. If you’re doing groundbreaking research, most things will fail, but you should learn from your failures and move forward stronger. It’s often important not to focus on yourself, but on the goals you’re passionate about in life.”
After five semesters of medical school, Oskar took a step back to explore other ideas: first philosophy, then the world of biomedical research at Lund. That curiosity soon led him to Scotland, where he became fascinated by mitochondria and their role in brain diseases. It was the beginning of a deeper dive into neurobiology, and after three years of research into Parkinson’s and Huntington’s, he earned his PhD in 2001.
The breakthrough
Then, about twenty years ago, Oskar Hansson’s research group made a groundbreaking discovery: Alzheimer’s could be predicted 5-10 years in advance using spinal fluid biomarkers (Hansson et al., Lancet Neurology). It was like spotting storm clouds long before the rain. This finding led to the biomarkers being used in clinical practice around the world to improve Alzheimer’s diagnosis, and in drug trials aimed at preventing the onset of dementia.
Blood instead of spinal fluid – and why it matters

In recent years, Oskar’s team developed a simple blood test to replace the spinal fluid method. It’s already in use in countries like the United States and Japan, and is just now being introduced in Sweden. It was a real game-changer for patients, because it is quick, gentle and easy to use in everyday clinics. With accuracy close to spinal fluid tests, it makes early diagnosis possible for many more people, even in places without advanced medical equipment. Oskar has also worked with organisations like the WHO to help ensure the test becomes available in low- and middle-income countries, making early Alzheimer’s diagnosis more equitable across the globe.
Deliberately recruited for success

Oskar has always worked with a clear focus, often setting ambitions that stretch over five to ten years. To reach them, he has deliberately recruited for success and built teams of driven and talented colleagues, ensuring that every objective is not only bold, but also meaningful for healthcare, and he adds:
“As a team, we have only chosen ambitious goals, that might revolutionise the healthcare, and where we believed we had the potential to be among the very best in the world.”
The mindset of a researcher mirrors that of an athlete
In many ways, the mindset of a researcher mirrors that of an athlete. Both require perseverance, precision and a relentless drive to improve.
That competitive spirit has been with him since childhood, when he played ice hockey with serious intent before realising that combining elite sport with other ambitions would be too difficult.
The discipline and focus he learned on the ice, however, never left him. Even today, he enjoys running in nature, always choosing the tougher path, because, as he puts it, “the more difficult the terrain, the more fun.”

Now, as his work takes him across the Atlantic, he jokes that one of his next challenges will be to quickly learn about major American sports teams, especially those tied to the cities where many of his colleagues are based, from Boston and Philadelphia to New York and Indianapolis. Without that knowledge, he admits, it may be hard to keep up with the conversations at coffee breaks and after-work gatherings.

For Oskar, research doesn’t seem so different from sport. The challenge is what fuels him, and the ultimate goal is not simply to participate, but to win – on behalf of patients, healthcare and science itself.
