The antipsychotic medication risperidone is more effective for initial treatment of mania in children diagnosed with bipolar disorder compared to other mood stabilizing medications, but it carries the potential for serious metabolic side effects, according to an NIMH-funded study published online ahead of print January 2, 2012, in the Archives of General Psychiatry.
Asian women who consumed an average of 200 milligrams or more of caffeine a day — the equivalent of roughly two cups of coffee — had elevated estrogen levels when compared to women who consumed less, according to a study of reproductive age women by researchers at the National Institutes of Health and other institutions. However, white women who consumed 200 milligrams or more of caffeine a day had slightly lower estrogen levels than women who consumed less. Black women who consumed 200 milligrams or more of caffeine a day were found to have elevated estrogen levels, but this result was not statistically significant.
A new multi-center study, including neurologists and neurosurgeons from the Perelman School of Medicine at the University of Pennsylvania, reveals that Deep Brain Stimulation (DBS) – a treatment for Parkinson’s disease (PD) patients with medication-resistant muscle movement impairment or tremors – can improve those symptoms and reduce medications for patients implanted with the device. The study appears Online First in Lancet Neurology.
Among obese individuals, having bariatric surgery was associated with a reduced long-term incidence of cardiovascular deaths and events such as heart attack and stroke, according to a study in the January 4 issue of JAMA. The study was conducted by Lars Sjostrom, M.D., Ph.D., of the University of Gothenburg, Sweden, and colleagues.
Adolescents diagnosed with schizophrenia and other psychoses appear to show greater decreases in gray matter volume and increases in cerebrospinal fluid in the frontal lobe compared to healthy adolescents without a diagnosis of psychosis, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals. The research was carried out by Celso Arango, M.D., Ph.D., of the Hospital General Universitario Gregorio Marañón, Madrid, Spain, and colleagues.
A hormone derived from visceral fat called adiponectin may play a role as a risk factor for development of all-cause dementia and Alzheimer disease (AD) in women, according to a study published Online First by the Archives of Neurology, one of the JAMA/Archives journals. The study was completed by Thomas M. van Himbergen, Ph.D., from the Lipid Metabolism Laboratory, Human Nutrition Research Center on Aging, Tufts University, Boston, and colleagues.
Women recently diagnosed with breast cancer have higher survival rates than those diagnosed in previous decades, according to the American Cancer Society. However, survivors continue to face health challenges after their treatments end. Previous research reports as many as 50 percent of breast cancer survivors are depressed. Now, University of Missouri researchers in the Sinclair School of Nursing say a meditation technique can help breast cancer survivors improve their emotional and physical well-being.
People with diets high in several vitamins or in omega 3 fatty acids are less likely to have the brain shrinkage associated with Alzheimer’s disease than people whose diets are not high in those nutrients, according to a new study published in the December 28, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology. The study author was Gene Bowman, ND, MPH, of Oregon Health & Science University in Portland, and a member of the American Academy of Neurology.
New research suggests that, in people who do not currently have memory problems, those with smaller regions of the brain’s cortex may be more likely to develop symptoms consistent with very early Alzheimer’s disease. The study is published in the December 21, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology.
An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, reports that abnormal sequences of DNA known as rare copy number variants, or CNVs, appear to play a significant role in the risk for early onset bipolar disorder. The findings will be published in the December 22 issue of the journal Neuron.
