Autism, Alzheimer’s, and bipolar disorder: can the development of these mental health conditions be influenced by the ketogenic diet? Increasingly, research suggests it might. 'For those it helps, it can be life-changing,' says neuroscientist Eline Dekeyster.

In the Dutch healthcare system, only MHC psychologists (GZ-psychologen) are licensed to practice psychology unsupervised.

Somatic symptoms, such as pain, itch, and fatigue have been shown to have a bidirectional relationship with mental symptoms. Although acute somatic symptoms serve some adaptive properties, chronic symptoms can instead lead to interference in daily activities and lower quality of life.

Adoptees in the Netherlands generally do not use more medication than their non-adopted peers.

Positive expectations can influence sensations of itch and evoke placebo effects, whereas negative expectations can trigger nocebo effects in itch. There is evidence that placebo effects can occur even when people know that they are taking a placebo. Little is known about how these so-called open-label…

While many healthcare professionals indicate that they frequently use placebo effects and their mechanisms, there is little formal training on how to deal with placebo and nocebo effects in clinical practice. This project aims to address this gap between scientific knowledge on placebo and nocebo effects…
