A study has shown that expectant mothers who eat excessive quantities of licorice during pregnancy could adversely affect their child’s intelligence and behavior. The study of eight-year-old children whose mothers ate large amounts of licorice when pregnant found that they did not perform as well as other youngsters on cognitive tests.
Rush University Medical Center has opened the Transcranial Magnetic Stimulation (TMS) Clinic to offer patients a safe, effective, non-drug treatment for major depression. TMS therapy is the first FDA-approved, non-invasive antidepressant device-based treatment clinically proven for treatment of depression. Science Daily reports that psychiatrists at Rush University Medical Center were among the first to test […]
A new neurosurgical procedure may prove helpful for patients with treatment-resistant depression. Bilateral epidural prefrontal cortical stimulation (EpCS) was found generally safe and provided significant improvement of depressive symptoms in a small group of patients, according to lead researcher Ziad Nahas, M.D. at the Medical University of South Carolina (MUSC).
More than half of people who take antidepressants for depression never get relief. New research from Northwestern University Feinberg School of Medicine finds that this is because the cause of depression has been oversimplified and drugs designed to treat it are aiming at the wrong target. Science Daily reports that a study from the laboratory […]
A new study found that chronic alcohol consumption reduces the number of new brain cells that form in the hippocampus of adolescent rhesus monkeys. This finding suggests that these cells are vulnerable to alcohol and their presence may be essential for preventing alcohol dependence.
Too much light at night can lead to symptoms of depression, according to a new study. Researchers found that mice housed in a lighted room 24 hours a day exhibited more depressive symptoms than did similar mice that had a normal light-dark cycle. However, mice that lived in constant light but could escape into a […]
Treating major depression is not a quick fix—it is a long, slow journey to restoring mental health. Although many antidepressant medications are available, no single biomarker or diagnostic test exists to predict which one is right for an individual. As a result, for more than half of all patients, the first drug prescribed doesn’t work, […]
About 20% of US soldiers returning from Iraq and Afghanistan are psychologically damaged, according to a Washington Post study. A substantial number of them suffer from post-traumatic stress disorder (PTSD), which carries with it a high rate of suicide. But doctors will now be able to forecast a soldier’s risk of developing PTSD, with the […]
In the first functional magnetic resonance imaging (fMRI) study of its kind, neurologists and psychiatrists at Columbia University have identified an area of the brain involved in the earliest stages of schizophrenia and related psychotic disorders. Activity in this specific region of the hippocampus may help predict the onset of the disease, offering opportunities for […]
New research shows the first definitive evidence that there is a chemical imbalance in the brains of those suffering from attention deficit and hyperactivity disorder (ADHD). The study, conducted by the US Department of Energy’s (DOE) Brookhaven National Laboratory in New York State, has found that ADHD sufferers have deficiencies in the way the brain […]
Clinically depressed people are less capable of finding pleasure in activities they used to enjoy, a recent study shows. Research published in the August 26 issue of the NeuroReport shows reduced brain function in the reward center of the brain in depressed individuals, when compared to healthy subjects. To investigate the effects of depression on […]
Science Daily reports that new technology provides insights into brain abnormalities in patients with anorexia nervosa that may contribute to the symptoms found in people with the disorder. Walter Kaye, MD, professor of psychiatry and director of the Eating Disorders Program at the University of California, San Diego, and colleagues describe dysfunction in certain neural […]
New research shows that exposing rats to a context associated with eating chocolate activates a part of the brain’s reward system known as the orexin system; this helps explain why eating can be triggered by environmental cues even in the absence of hunger. The findings could help scientists develop new drug treatments for overeating. As […]
For those who have never used drugs or experienced a dependence upon them, it is hard to understand the draw. Yet, when someone is dependent upon drugs or alcohol, the pleasure center within the brain is hijacked, which disrupts the normal functioning of its reward circuitry.
It wasn’t very long ago that most people considered addiction to be a moral failing rather than a treatable disease-it was largely thought that people who succumbed to drugs and alcohol were simply making poor decisions. Even when the American Medical Association announced in 1950 that alcoholism is a disease, people continued to hold onto […]
Long-term alcohol use can wreak havoc on a person’s system, eliminating the ability to function properly in certain areas. Now, new research suggests that while long-term sobriety can help to improve balance problems in alcoholics, some may not be able to regain full stability while standing. A post in Business Week captures certain elements of […]
