Automated analysis of the two language variables -- more frequent use of words associated with sound and speaking with low semantic density, or vagueness -- can predict whether an at-risk person will later develop psychosis with 93 percent accuracy.
New research, published in the journal Scientific Reports, shows that women undergo a significant mental as well as physical change during the late stages of pregnancy.
A new mathematical model that predicts which choices people will make in the Iowa Gambling Task, a task used for the past 25 years to study decision-making, outperforms previously developed models. Romain Ligneul of the Champalimaud Center for the Unknown in Portugal presents this research in PLOS Computational Biology.
Apolipoproten E (apoeE) is a major genetic risk factor for the development of Alzheimer's disease, yet it tends to be understudied as a potential druggable target for the mind-robbing neurodegenerative disease. Now a research team led by the University of South Florida Health (USF Health) Morsani College of Medicine reports that a novel apoE antagonist blocks apoE interaction with N-terminal amyloid precursor protein (APP) and reduces hallmark Alzheimer's-associated pathologies.
A new preclinical study by University of South Florida neuroscientists finds that anxiety-like behavior increases when early life adversity combines with high levels of FKBP5 -- a protein capable of modifying hormonal stress response. Moreover, the researchers demonstrate this genetic-early life stress interaction amplifies anxiety by selectively altering signaling of the enzyme AKT in the dorsal hippocampus, a portion of the brain primarily responsible for cognitive functions like learning and memory.
Controlling the frequency of 'brain waves' could help to improve people's recall of memories and potentially provide a key to unlock conditions such as Alzheimer's disease, according to a new article.
Experiences such as poverty, residential instability, or parental divorce or substance abuse, can affect executive function and lead to changes in a child's brain chemistry, muting the effects of stress hormones, according to a new University of Washington study.
Research at the University of York has shown that women are underrepresented in research into links between cannabis and psychosis, which could limit understanding of the impact of the drug.
We know bees get the concept of zero and can do basic math. Now researchers have discovered they may also be capable of connecting symbols to numbers. It's a finding that sheds new light on how numerical abilities may have evolved over millennia and even opens new possibilities for communication between humans and other species.
Nearly half the amplitude typically used in standard electroconvulsive therapy (ECT) seems to be effective at treating suicidal thoughts, investigators report.
