Bacterial meningitis is a life-threatening infectious disease of the brain that leaves many survivors with long-lasting neurological impairments. Now, researchers at Karolinska Institutet in Sweden show in a study on rats that the brain’s tool for waste clearance, the glymphatic system, malfunctions during bacterial meningitis, causing a buildup of toxic garbage that damages brain cells. The findings are published in the journal mBio.

Using gene expression data from different cell types in the inner ear and brain, researchers have been able to identify the cell types that mainly contribute to hearing loss. The findings confirm that hearing loss does not derive from the brain but from a distinct compartment in the cochlea, called the stria vascularis, which is the “powerhouse” of the inner ear. The study has been published in the American Journal of Human Genetics.

StratNeuro is partnering with the “Human Brains” initiative by Fondazione Prada, that will include in 2022 a series of events (local workshops, global roundtable discussions, conference and an exhibition at Prada Museum in Milano). Karolinska Institutet is one of 13 leading universities and institutions from across the world to participate in this initiative.

Researchers at Karolinska Institutet, together with British colleagues, have conducted the largest study to date in search of genetic markers about cluster headache. In the long term, it can hopefully pave the way for more effective treatments. The study is published in the scientific journal Annals of Neurology.

People who consume high levels of vitamin C and E in their diet may have a lower risk of Parkinson’s disease than people who get only small amounts of these nutrients, according to a new study from University of Milano-Bicocca, Italy, and Karolinska Institutet. The study was published in Neurology.

ME/CFS is a devastating disease with unknown genesis and no curative treatment. Some call the disease ME (Myalgic encephalomyelitis) and others CFS (Chronic fatigue syndrome), but the official name is ME/CFS. The disease has recently received increased worldwide attention after several cases of suicide among patients.
News
Many nerve cells in the brain region hypothalamus have unexpected origins and go through complex development programs, where millions of neurons assemble into a precisely knit network by birth. That is according to a study by researchers at Karolinska Institutet in Sweden and the Medical University of Vienna published in the journal Nature. The findings may further our understanding of hormonal diseases and their origins, according to the researchers.

Those with a family history of schizophrenia and men with lower IQ are more likely to struggle with treatment resistant schizophrenia than others with the mental disorder, according to a study by researchers at Karolinska Institutet in Sweden published in the journal Molecular Psychiatry. The researchers say the findings could be important in efforts to design novel drug treatments that improve cognition.
News
People with multiple sclerosis (MS) who also have depression are more likely to suffer debilitating symptoms early than people with MS who are not depressed, according to a study at Karolinska Institutet in Sweden that is published in the journal Neurology. The findings highlight the need for early recognition and treatment of depressive symptoms in patients with MS.

People with multiple sclerosis who can walk at a relatively normal speed and effectively process information are more likely to continue to participate in social activities, according to a new study by researchers at Karolinska Institutet in Sweden published in the Multiple Sclerosis Journal. The findings highlight the importance of integrating motor and cognitive rehabilitation in the care of patients with MS.

The timing of anemia—a common condition in late pregnancy—can make a big difference for the developing fetus, according to research at Karolinska Institutet published in JAMA Psychiatry. The researchers found a link between early anemia and increased risk of autism, ADHD and intellectual disability in the child. Anemia discovered toward the end of pregnancy did not have the same correlation. The findings underscore the importance of early screening for iron status and nutritional counselling.
News
It appears that when our nervous system is developing, only the most viable neurons survive, while immature neurons are weeded out and die. This is shown in a ground-breaking discovery by researchers at Karolinska Institutet in Sweden. The results indicate that the long-standing neurotrophic theory, which states that chance determines which cells will form the nervous system, needs to be revised.

On Tuesday 21 February Karolinska Institutet was visited by the Governor General of Canada David Johnston, his wife Sharon Johnston and the King and Queen of Sweden. The visit took place in conjunction with the state visit by the Governor General and his wife to Sweden at the invitation of the King.
News
The sympathetic nerve system has long been thought to respond the same regardless of the physical or emotional stimulus triggering it. However, in a new study from Karolinska Institutet published in the journal Nature Neuroscience, scientists show that the system comprises different neurons that regulate specific physiological functions, such as erectile muscle control.
News
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.
