Psychiatry is the treatment, study and prevention of mental disorders.
A new study exploring the impact of repeated sleep loss during a simulated working week has found that consuming caffeinated coffee during the day helps to minimize reductions in attention and cognitive function, compared to decaffeinated coffee.
Researchers at University of California San Diego School of Medicine, in collaboration with Dutch scientists, have found that certain metabolites -- small molecules produced by the process of metabolism -- may be predictive indicators for persons at risk for recurrent major depressive disorder.
Even people who consider themselves to be casual cigarette smokers may be addicted, according to current diagnostic criteria. Researchers at Penn State College of Medicine and Duke University found that many light smokers -- those who smoke one to four cigarettes per day or fewer -- meet the criteria for nicotine addiction and should therefore be considered for treatment.
As COVID cases rise, physically distancing yourself from other people has never been more important. Now a new UCLA study reveals how your brain navigates places and monitors someone else in the same location.
Drugs of abuse, like cocaine, are so addictive due in part to their cellular interaction, creating strong cellular memories in the brain that promote compulsive behaviors.
A team led by scientists in the Perelman School of Medicine at the University of Pennsylvania has engineered powerful new antimicrobial molecules from toxic proteins found in wasp venom.
A new study led by NorthShore University HealthSystem (NorthShore) and the University of Chicago took a novel approach to identifying SNPs influencing the risk of neuropsychiatric disorders like schizophrenia, bipolar and major depressive disorder, the institutions announced today.
Artificial intelligence can increase the effectiveness of drug repositioning or repurposing research, according to a study published in Translational Psychiatry.
Scientists at the Walter Reed Army Institute for Research (WRAIR) have recently demonstrated that cathepsin B, a well-studied protein important to brain development and function, can be used as biomarker, or indicator of severity, for traumatic brain injury.
To make new memories, our brain cells first must find one another. Small protrusions that bud out from the ends of neurons' long, branching tentacles dock neurons together so they can talk.
An adjusted sequence of genetic events should occur to allow the budding brain of a human embryo to turn into the organ that regulates human consciousness.
Professor Dr. Robert P. Doyle has developed a new drug to treat type 2 diabetes in millions of patients who are seeking to better control their blood sugar.
A study shows that patient-derived adult stem cells can be used to model major depressive disorder and test how a patient may respond to medication.
Older men who have a weak or irregular circadian rhythm guiding their daily cycles of rest and activity are more likely to later develop Parkinson's disease, according to a new study by scientists at the UC San Francisco Weill Institute for Neurosciences who analyzed 11 years of data for nearly 3,000 independently living older men.
Scientists carried out a genome-wide analysis of over 435,000 people, revealing 29 genetic variants associated with problematic drinking.
In recent years, genome-wide association studies have identified many different genetic variants associated with schizophrenia.
A study analyzing data from the Rhode Island Consortium for Autism Research and Treatment (RI-CART) found that only 3% of individuals diagnosed with autism spectrum disorder reported having fully received clinical genetic tests recommended by medical professional societies.
Fatty food may feel like a friend during these troubled times, but new research suggests that eating just one meal high in saturated fat can hinder our ability to concentrate - not great news for people whose diets have gone south while they're working at home during the COVID-19 pandemic.
Autism has long been associated only with behavioral and environmental factors, but the role of genetics in its development is now increasingly evident. Some 100 genes have been found to play a role in autism spectrum disorder, and another thousand are being studied to the same end.
A team of National Institutes of Health-funded researchers at the Medical University of South Carolina has found that deactivating a stress-signaling system in a brain area known for motivation and emotion-related behaviors decreases binge drinking.
