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.

Select memories could be 'erased', leaving others intact

Select memories could be 'erased', leaving others intact
Different types of memories stored in the same neuron of the marine snail Aplysia can be selectively erased, according to a new study by researchers at Columbia University Medical Center (CUMC) and McGill University and published in Current Biology. The findings suggest that it may be possible to develop drugs to delete memories that trigger anxiety and post-traumatic stress disorder (PTSD) without affecting other important memories of past events.

Magnetic stimulation fights depression by rewiring the brain

Magnetic stimulation fights depression by rewiring the brain
Americans spend billions of dollars each year on antidepressants, but the National Institutes of Health estimates that those medications work for only 60% to 70% of people who take them. In addition, the number of people with depression has increased 18% since 2005, according to the World Health Organisation, which this year launched a global campaign encouraging people to seek treatment.

Probiotics may relieve symptoms of depression

Probiotics may relieve symptoms of depression
Probiotics may relieve symptoms of depression, as well as help gastrointestinal upset, research from McMaster University has found. In a study published in the medical journal Gastroenterology, researchers of the Farncombe Family Digestive Health Research Institute found that twice as many adults with irritable bowel syndrome (IBS) reported improvements from co-existing depression when they took a specific probiotic than adults with IBS who took a placebo.

Patient's brainwaves may help fight PTSD

Patient's brainwaves may help fight PTSD
Technology using a patient's own brainwaves might offer hope against tough-to-treat PTSD, new research suggests. Post-traumatic stress disorder (PTSD) can develop as a reaction to a terrifying event, such as war, natural disasters, sexual assault and other physical violence or trauma. People with the condition may have prolonged anxiety, flashbacks, nightmares and other life-altering symptoms.
