Women battling stubborn major depression may have a surprising new ally in their fight—the muscle-building dietary supplement creatine.

creatineIn a new proof-of-concept study, researchers from three South Korean universities and the University of Utah report that women with major depressive disorder (MDD) who augmented their daily antidepressant with 5 grams of creatine responded twice as fast and experienced remission of the illness at twice the rate of women who took the antidepressant alone. The study, published Aug. 3, 2012, in the American Journal of Psychiatry online, means that taking creatine under a doctor’s supervision could provide a relatively inexpensive way for women who haven’t responded well to SSRI (selective serotonin reuptake inhibitor) antidepressants to improve their treatment outcomes.

“If we can get people to feel better more quickly, they’re more likely to stay with treatment and, ultimately, have better outcomes,” says Perry F. Renshaw, M.D., Ph.D., M.B.A, USTAR professor of psychiatry at the U of U medical school and senior author on the study.

If these initial study results are borne out by further, larger trials, the benefits of taking creatine could directly affect many Utahns. The depression incidence in Utah is estimated to be 25 percent higher than the rest of the nation, meaning the state has an even larger proportion of people with the disease. This also brings a huge economic cost to both the state and individuals. [continue reading…]

New technology has led to the creation of virtual humans who can interact with therapists via a computer screen and realistically mimic the symptoms of a patient with clinical psychological disorders, according to new research presented at the American Psychological Association’s 120th Annual Convention.

“As this technology continues to improve, it will have a significant impact on how clinical training is conducted in psychology and medicine,” said psychologist and virtual reality technology expert Albert “Skip” Rizzo, PhD, who demonstrated recent advancements in virtual reality for use in psychology.

Virtual humans can now be highly interactive, artificially intelligent and capable of carrying on a conversation with real humans, according to Rizzo, a research scientist at the University of Southern California Institute for Creative Technologies. “This has set the stage for the ‘birth’ of intelligent virtual humans to be used in clinical training settings,” he said.

Rizzo showed videos of clinical psychiatry trainees engaging with virtual patients called “Justin” and “Justina.” Justin is a 16-year-old with a conduct disorder who is being forced by his family to participate in therapy. Justina, the second and more advanced iteration of this technology, is a sexual assault victim who was designed to have symptoms of post-traumatic stress disorder.

In an initial test, 15 psychiatry residents, of whom six were women, were asked to perform a 15-minute interaction with Justina. Video of one such interaction shows a resident taking an initial history by asking a variety of questions. Programmed with speech recognition software, Justina responds to the questions and the resident is able to make a preliminary diagnosis.

Rizzo’s virtual reality laboratory is working on the next generation of virtual patients using information from this and related user tests, and will further modify the characters for military clinical training, which the U.S. Department of Defense is funding, he said. Some future patients that are in development are virtual veterans with depression and suicidal thoughts, for use in training clinicians and other military personnel how to recognize the risk for suicide or violence.

In the long term, Rizzo said he hopes to create a comprehensive computer training module that has a diverse library of virtual patients with numerous “diagnoses” for use by psychiatric and psychology educators and trainees. Currently, psychology and psychiatry students are trained by role-playing with other students or their supervisors to gain experience to treat patients. They then engage in supervised on-the-job training with real patients to complete their degrees. “Unfortunately, we don’t have the luxury of live standardized ‘actor’ patients who are commonly used in medical programs, so we see this technology as offering a credible option for clinical psychology training,” he said. “What’s so useful about this technology is novice clinicians can gain exposure to the presentation of a variety of clinical conditions in a safe and effective environment before interacting with actual patients. In addition, virtual patients are more versatile and can be available anytime, anywhere. All you need is a computer.”

    Blueprint for the brain

    Episode 1: Blueprint for the Brain from Science Bytes on Vimeo.

    The brain is composed of billions of cells called neurons. One neuron receives inputs from thousands of other neurons and sends out its signals to thousands more. We believe that if we understood the precise pattern with which neurons connect to each other, i.e. which neuron is connected with which other, we would understand how the brain works and how thoughts come about within the brain’s circuitry.

    Blueprint for the Brain – 6-minute film by PBS and the Public Library of Science explores how the three-pound lump of jelly inside our skulls enables us to do everything that makes us human, and how scientists are now beginning to decipher the architecture of the brain and its secret lives.

    A new report shows that the percentage of girls who experience a major depressive episode in the past year triples between the ages of 12 and 15 (from 5.1 percent to 15.2 percent respectively). The report by the Substance Abuse and Mental Health Services Administration (SAMHSA) also shows that an annual average of 1.4 million adolescent girls age 12 to 17 experienced a major depressive episode in the past year. In addition, the report reveals that adolescent girls aged 12 to 17 are three times more likely to have experienced a major depressive episode in the past year than their male counterparts (12 percent versus 4.5 percent).

    A major depressive episode is defined using criteria set forth in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) developed by the American Psychiatric Association. Under this definition, a major depressive episode is when a person experiences a period of depressed mood or loss of interest or pleasure for two weeks or longer and also experiences at least four other symptoms that reflect a change in functioning, such as problems with sleep, eating, energy, concentration and self-image.
    “It is crucial that we provide adolescent girls the coping skills and social supports they need to avoid the onset of depression, and to offer behavioral health services that foster resilience and recovery if they experience it,” said SAMHSA Administrator Pamela S. Hyde. “These efforts are a sound investment in girls’ health and well-being and in our nation’s future.” [continue reading…]
