Psychiatry is the treatment, study and prevention of mental disorders.
For the first time, scientists have linked distinct patterns of genetic mutations with OCD in humans using genome-wide analysis.
Levels of a protein called neurofilament light chain (NfL) in the blood can identify those who might have neurodegenerative diseases such as Down's syndrome dementia, motor neuron disease (ALS) and frontotemporal dementia, when clinical symptoms are not definitive.
Adolescents who had greater levels of an omega-3 fatty acid in their blood were less likely to acquire psychotic illness in early adulthood.
Researchers have demonstrated how cell “batteries” play a significant role in whether patients with the chromosomal deletion syndrome acquire schizophrenia.
Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells.
Neuroscientists have found that a single protein is critical to controlling sex disparities in the brain’s susceptibility to age-related neuron loss.
Researchers at the University of Calgary and The Hospital for Sick Children (SickKids), in Toronto, have discovered genetic risk factors for OCD that could help pave the way for earlier diagnosis and improved treatment for children and youth.
Abusive alcohol drinking considerably impacts human health. Alcoholism, better defined as Alcohol Use Disorders (AUD), includes a group of pathological entities related to alcohol-induced damage.
According to an analysis of sex variations in the genetics of bipolar disorder, schizophrenia, and major depressive disorders.
A tiny population of neurons known to be important to appetite appear to also have a significant role in depression that results from unpredictable, chronic stress, scientists say.
Findings from a new study on Alzheimer's disease could eventually help clinicians identify people at the highest risk for developing the progressive brain disorder.
A new study of autism risk genes by UC San Francisco and UC Berkeley scientists implicates disruption in prenatal neurogenesis - a process in which specialized "progenitor" cells give rise to new brain cells - in the development of autism spectrum disorders (ASDs).
The Institute for Scientific Information on Coffee (ISIC) published a new report today, titled 'Coffee and sleep in everyday lives', authored by Professor Renata Riha, from the Department of Sleep Medicine at the University of Edinburgh.
A research team has found 18 specific, fixed positions on chromosomes (called loci) that seem to be linked to post-traumatic stress disorder (PTSD).
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.
