Women who suffer depression during or after pregnancy have a higher risk of death by both natural and unnatural causes, a new study of childbirth in Sweden published in The BMJ reports. The increased risk peaks in the month after diagnosis but remains elevated for as long as 18 years afterwards.

Psychological gender differences persist in countries with improved living conditions, according to a study published in Perspectives on Psychological Science by researchers from Karolinska Institutet. Some differences become larger and others smaller as women seem to benefit more than men from improved living conditions. The findings confirm to some extent the so-called gender paradox.

There does not appear to be any profound differences between so-called exposure-based CBT and traditional CBT in the treatment of fibromyalgia, according to a study led by researchers at Karolinska Institutet. Both forms of treatment produced a significant reduction in symptoms in people affected by the disease. The study is one of the largest to date to compare different treatment options for fibromyalgia and is published in the journal PAIN.

After half a century in near-Earth orbit, humans are heading further out in space. First to the moon again. Then on to Mars! For this to go well, more research is needed on how space stresses the human body.

Bernard and Barbro Osher donate USD 2,100,000 (approx. SEK 23 million) to the Osher Center for Integrative Health at Karolinska Institutet. The donation follows an earlier donation in 2005 from the same donors.

Online cognitive behavioral therapy (CBT) shows promising effects on quality of life, as well as reduced healthcare consumption for patients with paroxysmal (i.e., intermittent) symptomatic atrial fibrillation, according to a new study in the Journal of the American College of Cardiology. According to the researchers, this is the world's first randomized controlled trial of CBT for patients with atrial fibrillation (AF).

Problems with managing anger can have severe consequences for the afflicted individual and their loved ones. A new study from the Centre for Psychiatry Research at Karolinska Institutet shows that four weeks of therapy delivered over the internet can help people with anger and aggression. The results have been published in the Journal of Consulting and Clinical Psychology.

How do people decide whether to intervene and help others in danger? Researchers at Karolinska Institutet now show that the same system in the brain that enables us to avoid danger is also activated during selfless, helping behaviour. The results are published in the scientific journal eLife.

Researchers at Karolinska Institutet in Sweden might have found an explanation for why people with self-injury behaviour generally feel less pain than others. The key seems to be a more effective pain-modulation system, a discovery that can benefit people seeking help for their self-harm. The findings are published in the journal Molecular Psychiatry.

A doctoral thesis at Karolinska Institutet has investigated whether Acceptance Commitment Therapy (ACT) can be used for individuals with Autism Spectrum Disorder. The results show that the treatment can be carried out in both a school environment and in psychiatric outpatient care and can have an effect on, among other things, perceived stress.

Children with migration backgrounds in Sweden are less likely than other children to receive recommended treatment for psychiatric diagnoses such as ADHD and depression, a paper from Karolinska Institutet published in the journal Epidemiology and Psychiatric Sciences reports.

What smells we like or dislike is primarily determined by the structure of the particular odour molecule. A collaborative study involving researchers from Karolinska Institutet, Sweden, and the University of Oxford, UK, shows that people share odour preferences regardless of cultural background. The study is published in the journal Current Biology.

Patients with bipolar disorder who experience manic episodes are more likely to show abnormal brain changes over time, according to one of the largest longitudinal brain imaging studies in its field to date. The study, led by researchers at Karolinska Institutet and University of Gothenburg in Sweden, also confirms links between bipolar disorder and accelerated brain ventricle enlargement. The findings are published online in the journal Biological Psychiatry.

Traumatic experiences such as assault or a road accident can give rise to nightmares, flashbacks and other mental reactions, and accessible therapy is needed to prevent exacerbation of the problems. Researchers at Karolinska Institutet have now completed what could be the largest evaluation to date of internet-delivered trauma-focused CBT (iCBT-T) for people who have recently experienced trauma. The study, which is published in Psychological Medicine, shows promising results.

Both humans and other animals learn quickly about dangers in their environment by observing the behavior of other individuals. Researchers at Karolinska Institutet now show that both rats and humans can use such social information to reactivate memories about threats that have been previously acquired through their own experiences.

Early intervention for disruptive behaviour disorders in children reduces the risk of antisocial development and psychiatric problems later in life. Parental training and child CBT are two interventions about which more needs to be known concerning the effects on disruptive behaviour disorders. According to a new doctoral thesis from Karolinska Institutet, both have a positive effect on such disorders, where severity should determine the choice of treatment.

Sweden was the first country in the world to introduce open-identity sperm donation, whereby adult children are entitled to obtain information about their donors. Researchers at Karolinska Institutet have now explored how such contacts and relations affect the parents of these young men and women. The study, which is published in Human Reproduction, shows that mothers often find it easier to accept the new situation.

Social anxiety disorder can cause considerable suffering in children and adolescents and, for many with the disorder, access to effective treatment is limited. Researchers at Centre for Psychiatry Research at Karolinska Institutet and Region Stockholm have now shown that internet-delivered cognitive behavioural therapy is an efficacious and cost-effective treatment option. The study is published in the journal JAMA Psychiatry.

Obsessive-compulsive disorder (OCD) in children and adolescents is associated with impaired education and worse general health later in life. Access to specialist treatment is often limited. According to a study from Centre for Psychiatry Research at Karolinska Institutet and Region Stockholm, internet-delivered cognitive behavioural therapy (CBT) can be as effective as conventional CBT. The study, published in the prestigious journal JAMA, can help make treatment for OCD more widely accessible.

Depressed children and teenagers have an increased risk of suffering from premature death and a wide range of illnesses later in life. That is according to a large observational study by researchers at Karolinska Institutet in Sweden. The findings highlight the need to look for other potential diseases following childhood or adolescent depression. Other psychiatric conditions, such as anxiety and substance misuse, can explain part of the association. The study is published in JAMA Psychiatry.

It is a known fact that sexual minorities are at a higher risk of developing poor mental health, when compared to heterosexuals. The stigma that sexual minorities face has been regarded as potentially the primary cause of this. A new thesis from Karolinska Institutet offers an insight into how stigma-related factors may work in a broader socio-ecological system, considering the complex interaction between structural, interpersonal and individual factors.

Worry about COVID-19 dominates some people’s lives in a way that has an impact on their health. A group of researchers at Karolinska Institutet in Sweden has developed a digital CBT programme that significantly reduced the participants’ unhelpful worry about the pandemic. The study is published in Psychotherapy and Psychosomatics and the programme is available through 1177 Vårdguiden.

Girls who have been sexually abused run a much higher risk of psychiatric ill health with depression and anxiety, leading to possible alcohol abuse and suicide. This persists even after intervention, reports a study from Karolinska Institutet published in European Child & Adolescent Psychiatry.

Researchers at Karolinska Institutet have compared two ways of delivering cognitive behavioral therapy to treat people with health anxiety, a condition that may increase in the wake of COVID-19. Out of about 200 study participants, half received Internet-CBT and half received conventional face-to-face CBT. The results, published in JAMA Psychiatry, show that Internet-delivered treatment had comparable effects, and may serve as an alternative in helping people who are worried about their health.

An international network of researchers in 10 countries are to study the effectiveness of homeschooling during the ongoing COVID-19 pandemic. The gathering of data via online surveys in the various languages is being led by researchers at Karolinska Institutet. The aims of the study are to look at the challenges facing families during the COVID-19 pandemic and to produce recommendations and technical methods for both homeschooling and teaching in general.

Researchers at Karolinska Institutet, Sweden have developed an online Cognitive Behavioural Therapy (CBT) program for people who struggle with excessive worry.

Stress-related conditions such as adjustment disorder and clinical burnout can be effectively treated with a 12-week cognitive behavioural programme, both when delivered as a face-to-face treatment and when delivered via the internet, according to a new doctoral thesis from Karolinska Institutet.

Cognitive Behavioural Therapy (CBT) for patients with social anxiety not only helps to reduce anxiety levels but also seems to protect against accelerated cellular ageing, a study involving researchers at Karolinska Institutet published in the journal Translational Psychiatry reports.

Researchers at Karolinska Institutet have developed an online Cognitive Behavioural Therapy (CBT) programme for the difficult-to-treat pain syndrome fibromyalgia. In her doctoral thesis, Maria Hedman-Lagerlöf shows that patients who receive the treatment experience fewer symptoms and enjoy better quality of life.

Refugees and other migrants who move to Sweden are initially less likely to be diagnosed with alcohol or drug addiction than the native population but over time their rates of substance abuse begin to mirror that of the Swedish born population. That is according to a new study by researchers at UCL in the U.K. and Karolinska Institutet in Sweden published in the journal PLOS Medicine.

The risk of suicide attempts and suicides among individuals with autism spectrum disorders is significantly higher than among the population in general. An especially high risk of suicidal behaviour is noted among women who in addition to autism also have ADHD. These are the findings of a population-based study from Karolinska Institutet in Sweden published in the journal Psychological Medicine.

A sleepless night not only leaves us fatigued and distracted, it also makes us interpret things more negatively and makes us more likely to lose our temper. Moreover, people suffering from a pollen allergy are at a high risk of some form of sleep disruption from the outset. This according to a new doctoral thesis from Karolinska Institutet that takes a neuroimaging approach to sleep loss.

Learning what is dangerous by watching a video or being told (known as social learning) has just as strong an effect on our decision-making as first-hand experience of danger, researchers at Karolinska Institutet in Sweden report. The results of the study, which is published in the journal PNAS (Proceedings of the National Academy of Sciences), can help to explain why we take irrational decisions.

Researchers at Karolinska Institutet have identified an evolutionarily preserved scent molecule in mammalian blood that attracts predators and repels prey. In the study, published in Scientific Reports, they also report that humans exposed to the smell become stressed and react to it as if they were prey.

Is it less wrong to avoid tax if everyone else is doing it? A new study from Karolinska Institutet demonstrates that our view of what is morally right or wrong is shaped by how widespread a particular behaviour is. The results, which are presented in the Journal of Experimental Psychology: General, can improve our understanding of the psychological mechanisms behind attitudinal change in society.

What happens in the brain when we see other people experiencing a trauma or being subjected to pain? Well, the same regions that are involved when we feel pain ourselves are also activated when we observe other people who appear to be going through some painful experience. This is shown in a study from Karolinska Institutet published in Nature Communications. But we are sensitive to different degrees to learning fear from other people and one explanation would appear to be found in the endogenou
