Depression is a serious medical illness that involves the brain. It's more than just a feeling of being "down in the dumps" or "blue" for a few days. If you are one of the more than 20 million people in the United States who have depression, the feelings do not go away. They persist and interfere with your everyday life.
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.
Researchers at the University of California, Davis, have created a genetically encoded sensor for detecting hallucinogenic substances.
Neuroscientists agree that a person's brain is constantly changing, rewiring itself and adapting to environmental stimuli. This is how humans learn new things and create memories. This adaptability and malleability is called plasticity.
Serotonin, or 5-hydroxytryptamine (5-HT), is a kind of neurotransmitter. 5-HT can regulate multifaceted physiological functions such as mood, cognition, learning, memory, and emotions through 5-HT receptors.
According to an analysis of sex variations in the genetics of bipolar disorder, schizophrenia, and major depressive disorders.
According to a recent study, sufficient rest during vacation time restored functions linked to DNA regulation in shift workers deprived of sleep.
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.
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.
Scientists have suspected mutations in a cellular cholesterol transport protein are associated with psychiatric disorders, but have found it difficult to prove this and to pinpoint how it happens.
A top exercise researcher and colleagues at the University of Virginia School of Medicine have launched an ambitious effort to understand the whole-body benefits of exercise so that doctors can use that information to prevent and treat disease.
Bacteria is all around us--not just in bathrooms or kitchen counters, but also inside our bodies, including in tumors, where microbiota often flourish. These "small ecologies" can hold the key to cancer drug therapies and learning more about them can help development new life-saving treatments.
Both of Andrew Kiselica's grandfathers developed dementia when he was in graduate school. As Kiselica was going through neuropsychology training in graduate school, he saw his mother's father become unable to walk or speak due to severe dementia.
New findings indicate that melatonin could be a potential treatment option for COVID-19.
In the synapses of nerve cells (neurons), there are hundreds of specialized proteins that are important for the functioning of the nervous system. If something goes wrong here, neurological or psychiatric diseases can be the result - Alzheimer's and Parkinson's, depression, and schizophrenia are just a few of them.
Researchers from the University of Seville have carried out a rigorous and detailed analysis of how artificial intelligence has been used with pregnant women over the last twelve years.
Almost six out of ten hospital trusts don’t have plans in place to manage or reduce their consumption of single-use plastics, according to BMA research on climate change
Using sophisticated 3D genomic mapping and integrating with public data resulting from genome-wide association studies (GWAS), researchers at Children's Hospital of Philadelphia (CHOP) have found significant genetic correlations between inflammatory bowel disease (IBD) and stress and depression.
Immediate actions are needed to limit the greenhouse gas emissions that are driving climate change that helps fuel wildfires, a Monash University study says.
In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals -- dopamine and serotonin -- are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.
Dr. O'Keefe speaks to AZoLifeSciences about his latest research that investigated how the pesco-mediterranean diet may lower the risk for heart disease.
