Increased brain acidity in psychiatric disorders
Decreased brain pH in the patients with schizophrenia and bipolar disorder has been considered to be the result of secondary factors associated with the diseases, such as medication and agonal state. However, the researchers of the present study suggest that decreased brain pH is a primary feature of the diseases themselves, based on the current findings from systematic investigation using five animal models, which are devoid of such secondary factors.

Manipulating brain network to change cognitive functions: New breakthrough in neuroscience
When an electric circuit breaks down, we can repair it by restoring connections in the circuit. Is it possible to restore the connections in our brain? And by doing so, is it possible to restore declining cognitive functions? Numerous regions of the brain are connected together and constitute a huge network. Researchers have developed a learning method to change cognitive function by manipulating connections in the brain. (2017-08-07)

Shared housing, shared behavior in mouse model of autism
Mice genetically modified to model autism spectrum disorders (ASD) cause changes in the behavior of their unmodified littermates when housed together. The findings, published in eNeuro, show how social environment shapes behaviors characteristic of mouse models for ASD and have implications for the interpretation of results obtained from mouse models of psychiatric disorders.

Lab-created mini-brains reveal how growing organ maintains neuronal balance
Scientists can now explore in a laboratory dish how the human brain develops by creating organoids -- distinct, three-dimensional regions of the brain. In research published in Cell Stem Cell, Yale scientists coaxed early stage stem cells to create and fuse two types of organoids from different brain regions to show how the developing brain maintains proper balance of excitatory and inhibitory neurons.

Study offers potential diagnostic and prognostic tools for HIV-associated neurocognitiv
UAlberta researchers believe they have a clearer picture of why people living with HIV so commonly suffer from dementia and other neurocognitive disorders. They found a number of critical peroxisomal proteins were virtually absent in the brains of HIV patients. The team believes the finding offers a strong clue as to the underlying cause of HIV-associated neurocognitive disorders (HAND) and that it could lead to new biomarkers to rapidly diagnose HAND in patients.

The Breivik terrorist attacks in Norway led to mental illness in Denmark
A new study shows that the number of Danes diagnosed with trauma -- and stressor-related disorders (such as post-traumatic stress disorder (PTSD)) increased substantially following the terrorist attacks carried out by Anders Breivik in Oslo and on the nearby island of Ut√łya in Norway in the summer of 2011. The study also suggests that the intense media coverage of the attack is likely to be partly responsible for this effect across national borders. (2017-07-17)

Screening those at risk of psychosis may help prevent violence, reduce stigma
A new study of young persons at clinical high-risk of developing psychosis has identified measures of violence potential that may be useful in predicting both the increased risk of future violent behavior and the actual development of psychosis. (2017-07-17)

Study shows childhood psychiatric disorders increase risk for later adult addiction
Children's health and well-being while growing up can be indicators of the potential health issues they may encounter years later. A study published in the July 2017 issue of the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP) suggests that a childhood psychiatric disorder increases the risk of developing addiction later in life. (2017-07-03)

Genomic copy number variants contribute to cognitive impairment in the UK
Genetic alterations of rare deletions or duplications of small DNA segments, called copy number variants (CNVs), have been known to increase risk of neurodevelopmental disorders such as schizophrenia, autism spectrum disorder, and intellectual disability. Now, a new study in Biological Psychiatry reports that even in the absence of a disorder, people carrying a CNV associated with these disorders may have impaired cognition. (2017-06-28)

Deaths among patients with opioid disorders may be cut by one-third by better care
Opioid-related deaths have surged in the United States during the past two decades as the nation battles an opioid epidemic. A new study finds that following three guidelines in providing medical care to people with an opioid addiction may cut deaths among such patients by as much as one-third. While the results need to be duplicated, researchers say the initial findings suggest the quality measures could go a long way toward improving patient outcomes. (2017-06-27)

Elevated rate of autism symptoms found in children with Tourette syndrome
Around one in five children with Tourette syndrome, a neurological disorder characterized by involuntary movements and vocalizations, met criteria for autism in a study headed by UC San Francisco. But this prevalence may be more a reflection of similarity in symptoms than actual autism, according to the study's researchers. (2017-06-22)

Meditation and yoga can 'reverse' DNA reactions which cause stress, new study suggests
Mind-body interventions (MBIs) such as meditation, yoga and Tai Chi don't simply relax us; they can 'reverse' the molecular reactions in our DNA which cause ill-health and depression, according to a study by the universities of Coventry and Radboud. (2017-06-15)

Quality of psychiatric treatment -- not number of beds -- should be focus of suicide prevention
Health care providers should focus on the overall quality of psychiatric care, depression screening and outpatient services to prevent suicide, not the number of available inpatient psychiatric beds, argue researchers from the University of Chicago and Columbia University in a new statistical analysis. (2017-06-14)

Study provides further support for genetic factors underlying addictions
Impairment of a particular gene raises increases susceptibility to opioid addiction liability as well as vulnerability to binge eating according to a new study. Dysfunction of the gene, casein kinase1-epsilon (CSNK1E), increases opioid's euphoric response and produces a marked increase in sensitivity to binge eating in a female experimental model but not in the male.

Study could help explain link between seizures and psychiatric disorders
In a new study published in Cell Reports, scientists at the Gladstone Institutes identified different types of neurons in a brain region called the reticular thalamus. A better understanding of these cells could eventually help explain how both seizures and certain psychiatric disorders can occur at the same time. (2017-06-06)
