Memory activation before exposure reduces life-long fear of spiders

25 August, 2016 - Uppsala universitet

Many people suffer from anxiety and fears, and a common treatment for these problems is exposure therapy. In a new study published in Current Biology, researchers at Uppsala University have shown how the effect of exposure therapy can be improved by disrupting the recreation of fear-memories in people with arachnophobia.

Bus drivers fight to stay awake

17 May, 2016 - VTI – Statens väg- och transportforskningsinstitut

Driving a bus in the afternoon during a split shift situation was shown in a recent study to be related to higher levels of self-reported sleepiness, higher levels of physiological sleepiness and increased response times, compared to an afternoon shift. Today the Swedish researcher, Anna Anund, speak about this at the conference RS5C at the Windsor Flórida Hotel in Rio de Janeiro.

Simulator study shows preference of decorative lighting in tunnel

17 May, 2016 - VTI – Statens väg- och transportforskningsinstitut

Maintaining high levels of road traffic safety is always important, especially when the road is in a long tunnel. A simulator study at VTI, the Swedish National Road and Transport Research Institute, shows that different types of lighting in tunnels affect drivers in different ways. These results will be presented this week at RS5C, Road Safety on Five Continents, in Rio de Janeiro.

New study shows how shift work affect cognitive functions

17 May, 2016 - Uppsala universitet

A new study from Uppsala University shows that compared to non-shift workers, shift workers needed more time to complete a test that is frequently used by physicians to screen for cognitive impairment. However, those who had quit shift work more than five years ago completed the test just as quick as the non-shift workers. The findings are published in the journal Neurobiology of Aging.

Risk of schizophrenia and other psychoses three times higher in refugees

16 March, 2016 - Karolinska Institutet

A study of 1.3 million people in Sweden found that the risk of being diagnosed with schizophrenia or other psychoses was three times higher in refugees than in the Swedish-born population. The research team from Karolinska Institutet in Sweden and the University College London (UCL), UK, found that more than one in a thousand refugees were diagnosed with schizophrenia or other psychoses every year.

Surprisingly long learning curve for surgeons operating on oesophageal cancer

8 March, 2016 - Karolinska Institutet

According to a major Swedish cohort study from researchers at Karolinska Institutet and Imperial College London, a surgeon who operates on oesophageal cancer must have performed 60 operations to prevent any lack of experience adversely affecting the long-term survival of the patients. The finding, which is published in the Journal of Clinical Oncology, has potential significance for clinical practice.

Imagined ugliness can be treated with internet-based CBT

3 February, 2016 - Karolinska Institutet

Imagined ugliness, or body dysmorphic disorder (BDD) as it is known, can be treated with internet-based CBT, according to a recent randomised study, the first of its kind ever conducted. The new treatment, which is published in the British Medical Journal, has been developed by researchers at Sweden’s Karolinska Institutet and has the potential to increase access to care for sufferers of BDD.

Attention neuron type identified

14 January, 2016 - Karolinska Institutet

Researchers at Karolinska Institutet have identified for the first time a cell type in the brain of mice that is integral to attention. By manipulating the activity of this cell type, the scientists were able to enhance attention in mice. The results, which are published in the journal Cell, add to the understanding of how the brain’s frontal lobes work and control behaviour.

Exposure to noise during pregnancy increases risk of hearing dysfunction in children

9 December, 2015 - Karolinska Institutet

A recently published study from the Institute of Environmental Medicine (IMM) at Karolinska Institutet shows that exposure to noise during pregnancy can damage the child’s hearing, with an 80 percent increase in risk in occupational environments with particularly high decibel levels. The results strongly indicate that pregnant women should not be exposed to loud noise.

Link between PCOS in the mother and autism in the child

8 December, 2015 - Karolinska Institutet

Children born to mothers with polycystic ovarian syndrome, PCOS, are at an increased risk of developing autism spectrum disorders, according to a new epidemiological study from Sweden’s Karolinska Institutet. The findings, which are published in the journal Molecular Psychiatry, support the notion that exposure to sex hormones early in life may be important for the development of autism in both sexes.
