The study is published in the scientific journal Science Advances.

It is quite common that individuals who have one psychiatric condition, also qualify for other psychiatric conditions.

Low concentrations of air pollutants are associated with poorer health, and previous research has found a link between air pollution and dementia risk. Researchers at Karolinska Institutet, among others, have now investigated this connection. The study, published in the journal Neurology, contributes to a better understanding of the biological mechanisms that might explain why air pollution seems to increase the risk of developing dementia.

Self-harming behaviour in young people causes suffering and increases the risk of suicide. Researchers at Karolinska Institutet and Region Stockholm have now studied if an internet-delivered emotion regulation therapy can reduce self-harm in youth. The study, which is published in JAMA Network Open, suggests that the therapy is effective.

You may know about depression and ADHD - but what about the p factor, emotion regulation and symptom networks? We need more concepts for mental health difficulties, say researchers.

Vaccination protects against severe COVID-19 but not against infection. Researchers at Karolinska Institutet and Danderyd Hospital now show that protection against infection with the new omicron variants is linked to mucosal IgA antibodies, which are not induced by vaccination. These are the findings of two studies recently published in The Lancet Infectious Diseases, and The Lancet Microbe, and could explain the limited protection by currently available vaccines against infection.
