Brains of people at risk of psychosis exhibit a pattern that can help predict whether they will go on to develop full-fledged schizophrenia, a new Yale-led study shows. The findings could help doctors begin early intervention therapies for those most likely to develop the disabling disorder. (more…)
AUSTIN, Texas — Your brain transmits information about your current location and memories of past locations over the same neural pathways using different frequencies of a rhythmic electrical activity called gamma waves, report neuroscientists at The University of Texas at Austin.
The research, published in the journal Neuron on April 17, may provide insight into the cognitive and memory disruptions seen in diseases such as schizophrenia and Alzheimer’s, in which gamma waves are disturbed. (more…)
Over the last three decades U.S. parents have committed filicide — the killing of one’s child — about 3,000 times every year. The horrifying instances are often poorly understood, but a recent study provides the first comprehensive statistical overview of the tragic phenomenon. The authors also suggest underlying hypotheses of motives with the hope of spurring research on filicide prevention.
PROVIDENCE, R.I. [Brown University] — Instances in which parents kill their children may seem so horrifying and tragic that they defy explanation. Published scientific and medical research, meanwhile, doesn’t offer much epidemiological context to help people understand patterns among such heinous crimes. A paper in the March edition of the journal Forensic Science International provides the first comprehensive statistical analysis of filicide in the United States, drawing on 32 years of data on more than 94,000 arrests. The study also explores possible underlying psychiatric and biological underpinnings of filicide. (more…)
What we don’t know: Neuroscience research at CMHC
The third floor of the CMHC houses the Clinical Neuroscience Research Unit (CNRU), an inpatient and outpatient research facility. It’s an honor to be asked to start a dialogue with you about what we do on the CNRU. Over the next few months, I’d like to introduce you to the scientists and clinicians and their teams that work on the CNRU. Today I’d like to introduce you to some of the things we do on the 3rd floor.
Just as others in the building, my CNRU colleagues and I come to work to tackle the problems addressed on the other floors of the CMHC: the debilitating symptoms of mental illness including depression, hallucinations, delusions, drug addiction and anxiety to name a few. (more…)
A new study, co-authored by Eric Achtyes from Michigan State University’s College of Human Medicine, shows that people with serious mental illness have better luck quitting smoking and avoiding relapse through extended treatments using varenicline, a smoking cessation drug, and cognitive behavioral therapy.
The study was recently published in the Journal of the American Medical Association. (more…)
The first 30 seconds of a social encounter is crucial for people with symptoms of schizophrenia for establishing contact with people, according to new research carried out at Queen Mary University of London and the University of Exeter Medical School.
Using motion capture technology more commonly found in the film industry, the researchers studied social interactions of patients in a group and analysed the patterns of verbal and non-verbal communication. (more…)
Being left-handed has been linked to many mental disorders, but Yale researcher Jadon Webb and his colleagues have found that among those with mental illnesses, people with psychotic disorders like schizophrenia are much more likely to be left-handed than those with mood disorders like depression or bipolar syndrome.
The new study is published in the October-December 2013 issue of the journal SAGE Open. (more…)
Good mental health and clear thinking depend upon our ability to store and manipulate thoughts on a sort of “mental sketch pad.” In a new study, Yale School of Medicine researchers describe the molecular basis of this ability — the hallmark of human cognition — and describe how a breakdown of the system contributes to diseases such as schizophrenia and Alzheimer’s disease.
“Insults to these highly evolved cortical circuits impair the ability to create and maintain our mental representations of the world, which is the basis of higher cognition,” said Amy Arnsten, professor of neurobiology and senior author of the paper published in the Feb. 20 issue of the journal Neuron.
