Fast driver, fast life: genetics and everyday behaviour reflected in risky driving
In early October, Tõnis Tokko – a PhD student in our group – presented his research at the ECNP annual conference, an international meeting where researchers from all over the world present their latest findings on topics related to neuroscience and mental health. His presentation about the links between risk-taking behaviour in traffic, unhealthy lifestyle and genetics attracted a lot of media attention. You can read the full press release below. But let me summarize for you what Tõnis found. Tõnis’s presentation was about risk-taking in traffic and how one genotype and unhealthy lifestyle is associated with that. Both risk-taking...
Why gut health is important for your brain and immune system
We recently saw a video (see footnote below) on the CNN website where medical correspondent Dr. Sanjay Gupta explains why gut health is important for immunity. This video is very short and many complex terms are mentioned here. So we thought we’d give you a bit more context about this topic. What’s a microbiome test? What we think Dr. Gupta means here is sending in a sample of your feces to a lab ran by either a hospital or company to identify which types of bacteria and how many of these live in your gut. It is certainly interesting to...

Can the gut microbiota predict behavior in mentally healthy individuals?
Maintaining mental health is important. The gut microbiota, mainly composed of bacteria, is considered to play a pivotal role in retaining mental health. It is not surprising that most gut microbiota-brain related studies are focused on diagnosed mental disorders,[2] due to their severity and urgency. With a better understanding of the role the gut microbiota plays in mental disorders, researchers start their explorations in a wider group, that does not have a disorder. This group is often called the “neurotypical population”. The neurotypical population is defined as medically and psychologically healthy individuals who have a normal pattern of neurodevelopment.[1] Though...
Getting ready for the next lockdown- is coping with a piece of cake a good idea?
During the COVID-19 pandemic, many people’s personal as well as work situation changed. People who previously worked in an office now work from home. Other people were put on short-time work or even lost their jobs. This new time – with all its restrictions and recommendations to stay at home and to not socialize – drove people to start something unexpected: they started baking! In this blog, we will look at what baking does to people as a coping mechanism, based on a survey by a Canadian research group. Neuroscientist Melissa Chee and her colleagues from the Carlton university in...
Fecal microbiota transplantation and Alzheimer’s disease
Alzheimer’s disease is a neurological disorder that causes dementia (e.g. memory loss). As its prevalence among elderly individuals is expected to increase during the next decades, Alzheimer’s disease has become one of the major public health problems worldwide. Many researchers are therefore looking for new ways to prevent or treat Alzheimer’s disease. One promising new technique is poop transplants, officially called “fecal microbiota transplantations”. This method could be a promising new treatment for Alzheimer’s disease, although at this moment much more research is needed before it can really be applied to patients on a large scale. How a disturbed gut...

Does impulsivity increase unhealthy eating behaviors and are there any differences between men and women?
It is often thought that impulsivity results in unhealthy eating. For instance, overeating due to stress, or making unhealthy food choices in response to advertisements. Up until now, most research has focused on only the dysfunctional aspects of impulsivity, while I wanted to know if functional impulsivity is also linked to unhealthy eating. I was also interested in differences between men and women. From my study, I concluded that there was no link between either form of impulsivity and unhealthy eating, nor was there a difference between men and women. However, this could be due to the homogeneity of our...
How your morning coffee might save you from skin cancer
Every few years a new group of scientists publishes their recent study results on “bad” and “healthy” food and gives new dietary advice. As “superfoods” like avocado, chia seeds and goji berries come and go and fill the pockets of marketing experts, the question remains which nutrients and aliments are really helping to live a longer, healthier life. Especially interesting for many people is the question of food-related risk factors for cancer. There are aliments that have been connected to a higher risk of developing cancer types like lung, skin or liver cancer. However, these results aren’t always consistent and...
Why you should limit added sugar in your diet
There are many sources of sugar in our diet. So-called natural present sugar naturally occurs in food. One example is milk sugar (lactose) found in milk and yoghurt. Sugars in fruits are another example of natural sugar. In addition to sugar, these foods also contain important nutrients like vitamins and minerals. There are also a lot of foods that contain additional, added sugar. Added sugar is usually understood as sugar added to food during food preparation or processing [1]. There are several reasons for adding sugars to food. Commonly they are used as sweeteners and to preserve food. They are...
The importance of traces
You might know zinc as part of metal objects, batteries or as anti-corrosion agent. But did you know that very small amounts of zinc are essential for our bodies (and mind) to function well? Zinc is an essential trace element for humans (as well as animals, plants and microorganisms). Second only to iron, zinc is one of the most abundant trace elements in our body, which typically contains about 2-4 mg of zinc. There is a great number of zinc-dependent biological processes as hundreds of enzymes and thousands of protein domains require zinc. Zinc is essential for growth and development...
Differences in lifestyle habits between children with and without ADHD
There is an increasing interest in lifestyle factors and their impact on mental health. Lifestyle factors refer to behaviors that have an impact on your health and quality of life [1]. Examples of lifestyle factors are physical activity, diet, sleep behavior and use of tobacco and alcohol. Different lifestyle factors have been proposed as precursors or consequences of ADHD [2]. Therefore one might wonder: how do children and adolescents with ADHD differ from children and adolescents without ADHD on several lifestyle factors? In one study [3] parents were asked to fill out a lifestyle questionnaire about, among other things, the...
