Anxiety Can Be Efficiently Treated with Exercise, Study Says

In a new study, researchers from the University of Gothenburg, Sweden, found that moderate and strenuous exercise help alleviate symptoms of anxiety, even if the condition is chronic.Anxiety Can Be Efficiently Treated with Exercise, Study Says

For the study, a team of researchers recruited 286 patients from primary care services in Gothenburg and the northern part of Halland County. Half of the enrolled patients experience anxiety for ten years and over. The average age of the participants was 39 years, and 70% were female.

All participants were divided into two groups. The first group had to perform the exercise of moderate or strenuous intensity for 12 weeks, while another group has just received advice on physical activity in accordance with the public health recommendations.

The first author of the study, Malin Henriksson, a doctoral student at Sahlgrenska Academy at the University of Gothenburg, says: “There was a significant intensity trend for improvement — that is, the more intensely they exercised, the more their anxiety symptoms improved.”

Probiotics May Help Reduce Symptoms of Depression

A new study, published in the journal BMJ Nutrition, Prevention & Health, suggests that probiotics, as well as a combination of prebiotics and probiotics, may help reduce symptoms of depression.Probiotics May Help Reduce Symptoms of Depression

For the study, the researchers reviewed English-language studies published between 2003 and 2019 and included human participants aged 18 years and older, had clinically confirmed anxiety or depression, and received a dietary prebiotic or probiotic intervention.

The authors of the review found that despite all the studies were significantly different, they all clearly demonstrated a positive benefit of a dietary probiotic intervention for the reduction of symptoms of depression. At the same time, they found little evidence that probiotics could reduce symptoms of anxiety.

Red Wine Compound May Become Depression Treatment in Future

A new study in mice, conducted by the researchers from Xuzhou Medical University in China, suggests that resveratrol, a red wine compound, can be used for the treatment of depression and anxiety in the future.Red Wine Compound May Become Depression Treatment in Future

In this study, the scientists used animal models and cultured mouse neurons (similar to those in the human hippocampus) to help explain the effect of the compound on rodent behaviors.

Resveratrol, which appears to reduce anxiety and depression in mice, seems to work by inhibiting PDE4D (a member of the PDE4 family that believed to be particularly important in cognition and depression) and activating cAMP (cyclic adenosine monophosphate) signaling.

Co-lead author Dr. Ying Xu, Ph.D. says: “Resveratrol may be an effective alternative to drugs for treating patients suffering from depression and anxiety disorders.”

A Machine Learning Algorithm Can Detect Depression in Children’s Speech

Scientists from the University of Vermont, US, developed a machine learning algorithm that is able to detect signs of depression and anxiety in the speech of children under the age of 8.a machine learning algorithm can diagnose a depression in children

The researchers used an adapted version of a mood induction task called the Trier-Social Stress Task, intended to cause feelings of stress and anxiety in the subject. During the study, 71 children aged 3 and 8 were asked to tell a short story within 3 minutes. They were told that they would be judged based on how interesting it was.

To analyze children’s speech, scientists used a machine learning algorithm. The algorithm proved to be very successful at diagnosing children.

Study senior author Ryan McGinnis says: “The algorithm was able to identify children with a diagnosis of an internalizing disorder with 80% accuracy, and in most cases that compared really well to the accuracy of the parent checklist.”

A Compound in Lavender Can Lessen Anxiety without Impairing Movement

New Japanese research finds that linalool, a fragrant compound in lavender, can help lessen anxiety by stimulating the nose to pass signals to the brain, not by being absorbed into the bloodstream through the lungs.lavender lessen anxiety

World Health Organization (WHO), as of 2015, estimates that 3.6 percent of the global population suffers from anxiety disorders. The number varies from country to country.

Study co-author Dr. Hideki Kashiwadani, of the Graduate School of Medical and Dental Sciences at Kagoshima University, says: “Our study also opens the possibility that relaxation seen in mice fed or injected with linalool could, in fact, be due to the smell of the compound emitted in their exhale breath.”
