Research reveals a better way of treating depression

Research reveals a better way of treating depression
Scientists on the Florida campus of The Scripps Research Institute (TSRI) have discovered a new target for treating major depressive disorder, a disease that affects more than 16 million American adults. Their research shows that individuals with high levels of an enigmatic receptor called GPR158 may be more susceptible to depression following chronic stress.

An unwanted side effect of human brain development

An unwanted side effect of human brain development
Schizophrenia may have evolved as an 'unwanted side effect' of the development of the complex human brain, a new study has found. The study identified changed gene expression in the area of the brain that is most different between humans and animals, including our closest species, non-human primates. Published by the Nature publishing journal, Schizophrenia, the study was undertaken by a group of researchers from Swinburne, The Florey Institute of Neuroscience & Mental Health and University of Melbourne.

A possible effective treatment for autism spectrum disorder

A possible effective treatment for autism spectrum disorder
Human chromosome 16p11.2 deletion syndrome is caused by the absence of about 27 genes on chromosome 16. This deletion is characterised by intellectual disability; impaired language, communication, and socialisation skills; and autism spectrum disorder or ASD. Research from the laboratories of Mark Bear at MIT and Jacqueline Crawley at the University of California at Davis, has identified a potential therapeutic for ASD.

Brain imaging can identify individuals with suicidal thoughts

Brain imaging can identify individuals with suicidal thoughts
Researchers led by Carnegie Mellon University's Marcel Just and the University of Pittsburgh's David Brent have developed an innovative and promising approach to identify suicidal individuals by analysing the alterations in how their brains represent certain concepts, such as death, cruelty and trouble. Suicidal risk is notoriously difficult to assess and predict, and suicide is the second-leading cause of death among young adults in the United States.

VR helps study origins of fear and anxiety

VR helps study origins of fear and anxiety
Our irrational fears are both very real and are also figments of our imagination. By manipulating what we think of as reality, researchers at Stanford University are working to understand the source of our anxieties and how to alleviate them. In order to do so, they built a virtual reality chamber where one’s fears can be generated by a computer. In 1984, the book, this was done in a special room as well, but with real objects of fear and for opposite reasons.

More precise treatments for depression in women

More precise treatments for depression in women
Among women in the United States, depression is at epidemic levels: Approximately 12 million women in the U.S. experience clinical depression each year, and more than 12% of women can expect to experience depression in their lifetime. Moreover, many experts believe the numbers are likely higher, given the degree of under-reporting about the condition, the fact that depression in women is often misdiagnosed and the fact that fewer than half of women who experience clinical depression will ever seek care.

Machine learning algorithms help predict schizophrenia

Machine learning algorithms help predict schizophrenia
IBM scientists and the University of Alberta in Edmonton, Canada, have published new data in Nature's partner journal, Schizophrenia, demonstrating that AI and machine learning algorithms helped predict instances of schizophrenia with 74% accuracy. This retrospective analysis also showed the technology predicted the severity of specific symptoms in schizophrenia patients with significant correlation, based on correlations between activity observed across different regions of the brain.

Scanning reveals that depression changes brain structure

Scanning reveals that depression changes brain structure
Changes in the brain's structure that could be the result of depression have been identified in a major scanning study. Alterations were found in parts of the brain known as white matter, which contains fibre tracts that enable brain cells to communicate with one another by electrical signals. White matter is a key component of the brain's wiring and its disruption has been linked to problems with emotion processing and thinking skills.

PTSD research identifies potential path to treatment

PTSD research identifies potential path to treatment
A study of post-traumatic stress disorder (PTSD)—conducted by the VA National Center for PTSD (NCPTSD), National PTSD Brain Bank, and Yale University—has identified a new potential mechanism contributing to the biology of the disorder that may be targeted by future treatments. Among combat veterans, PTSD is a common and disabling condition that is associated with high suicide risk, and in some cases it is difficult to treat effectively.

Video games serve as coping mechanism for military personnel

Video games serve as coping mechanism for military personnel
Growing up in a military family, Jaime Banks is accustomed to the transient yet structured life of military service. After watching family members find stress relief through video games, the West Virginia University professor saw a connection to her research on communication technology and human identity. "Some members of my extended family serve in the military, and I started to notice how video games play a big role in their lives," said Banks, an assistant professor of communication studies.
