Study provides first evidence of neural link between sleep loss and psychiatric disorders

10-22-2007 · EurekAlert!

In the first neural investigation into what happens to our emotional stability when we lose sleep, researchers from UC Berkeley and Harvard Medical School have found that while a good night's rest can regulate our mood and help us cope with the next day's emotional challenges, sleep deprivation excessively boosts the part of the brain most closely connected to depression, anxiety and other psychiatric disorders.

  1. Promising treatment for post-traumatic stress disorder sleep disturbances
    04-17-2007 · EurekAlert!
    For sufferers of post-traumatic stress disorder, sleep disturbances are among the most treatment-resistant symptoms and can lead to drug and alcohol abuse and even suicide. Previously, there has been little success in treating these sleep disorders with psychopharmacologic approaches. In a study in the April 15 issue of Biological Psychiatry, researchers have found that an inexpensive, widely available drug was successful in reducing symptoms in chronic PTSD patients.

  2. Dragonfly's metabolic disease provides clues about human obesity
    11-20-2006 · EurekAlert!
    Parasite-infected dragonflies suffer the same metabolic disorders that have led to an epidemic of obesity and type 2 diabetes in humans, according to research to be published in the Proceedings of the National Academy of Science. The discovery expands the known taxonomic breadth of metabolic disease and suggests that the study of microbes found in human intestines may provide a greater understanding of the root causes of human metabolic dysfunction.

  3. Antioxidants decrease disease in a Drosophila model of Alzheimer's disease
    12-14-2006 · EurekAlert!
    Alzheimer's disease (AD) is a neurodegenerative disorder in which brain cells damaged by naturally occurring chemicals known as reactive oxygen species have been observed. Whether this oxidative damage causes neurodegeneration or is a consequence of it has not been previously determined. A study now indicates that oxidative damage contributes to neurodegeneration in a Drosophila model of disorders such as AD, suggesting that targeting antioxidant pathways might provide a new approach for treating individuals with AD.

  4. In utero exposure to smoking by mother can increase risk of ADHD
    05-23-2007 · EurekAlert!
    Women smokers who become pregnant have long been encouraged to reduce or eliminate their nicotine intake. A new study being published in the June 15th issue of Biological Psychiatry provides further reason to do so, as it presents new evidence that in utero exposure to smoking is associated with attention deficit/hyperactivity disorder (ADHD) problems in genetically susceptible children.

  6. Research suggests fitness reduces inflammation
    07-06-2007 · EurekAlert!
    A number of studies have suggested that regular exercise reduces inflammation -- a condition that is predictive of cardiovascular and other diseases, such as diabetes. If such a link exists, the nature of the relationship is by no means fully understood.A recent study by researchers at the University of Illinois provides new evidence that may help explain some of the underlying biological mechanisms that take place as the result of regular exercise.

  8. Potential new approach to treat cognitive impairments in schizophrenia
    09-24-2007 · EurekAlert!
    A new study reports important evidence for a potential new treatment approach for those diagnosed with schizophrenia. Schizophrenia is considered one of the most devastating of the major psychiatric disorders, which has three distinct facets, often referred to as 'positive' (hallucinations, delusions), 'negative' (blunted emotions, reduced capacity for pleasure), and 'cognitive' (impairments in attention, memory, and problem-solving) symptoms.

    Mass. General Institute for Neurodegererative Disorders researchers have identified a compound that may lead to a treatment that could protect against the effects of Huntington's Disease. Their report describes how a small molecule called C2-8 appears to delay the loss of motor control and reduce neurological damage in a mouse model of the disorder.
