ScienceDaily features breaking news about the latest scientific discoveries on everything from astrophysics to zoology from the world's leading universities and research organizations. Read current research on psychiatric disorders such as depression, OCD, schizophrenia, panic disorder, bipolar disorder and more.
Findings from a new study of large-scale systems in the brain could improve understanding of the symptoms and causes of bipolar disorder, schizophrenia, depression, and other mental illnesses. Researchers detail their investigation into brain network connectivity in patients with psychotic disorders.
Adolescents in China who either spend more time on screen activities, such as watching TV or surfing the Web, or less time on non-screen activities, including physical activity, are at risk and significantly more likely to experience depression, according to a new study.
Scientists have shown that transplanting gut bacteria, from an animal that is vulnerable to social stress to a non-stressed animal, can cause vulnerable behavior in the recipient. The research reveals details of biological interactions between the brain and gut that may someday lead to probiotic treatments for human psychiatric disorders such as depression.
A machine learning algorithm can detect signs of anxiety and depression in the speech patterns of young children, potentially providing a fast and easy way of diagnosing conditions that are difficult to spot and often overlooked in young people. If undiagnosed, they can lead to an increased risk of substance abuse and suicide later in life.
A newly identified epigenetic hotspot for schizophrenia and bipolar disorder may give scientists a fresh path forward for devising more effective treatments and biomarker-based screening strategies. More than 100 million people worldwide have either schizophrenia or bipolar disorder, which are characterized by periods of hallucinations, delusions and irregular thought processes. They are both associated with overproduction of the neurotransmitter dopamine, a key regulator of reward-seeking behavior, emotional responses, learning and movement, among other functions.
In the largest study of its kind, involving more than 50,000 subjects in 14 countries, researchers at more than 200 collaborating institutions have identified 20 new genetic associations with one of the most prevalent and elusive mental illnesses of our time -- bipolar disorder.
