China News Service, Beijing, January 19 (Reporter Sun Zifa) In life, many people may be more or less, strong or weak, affected and troubled by obsessive-compulsive disorder. How to effectively alleviate and treat obsessive-compulsive disorder has always been a concern. .

  A new neuroscience research paper published by Springer Nature's professional academic journal "Nature-Medical" stated that the study found that low-frequency electrical stimulation of brain network activity patterns that control learning and reward choice behavior may be reduced People’s compulsive behavior has an effect of up to 3 months.

The results of this study show that non-invasive, personalized brain circuit therapy has the potential to treat obsessive-compulsive behaviors and related symptoms.

  Obsessive-compulsive disorder is very common in the general population, causing great distress to patients, but there are few effective treatment options for patients with obsessive-compulsive disorder.

Previous studies have linked compulsive behavior with excessive habitual learning as a reward function for reinforcement learning.

  The corresponding author of the paper, Robert Reinhart of Boston University and his colleagues used a non-invasive method to measure the brain activity patterns of 124 subjects participating in a reinforcement learning task. They stimulated them with low-frequency currents. The subject's specific brain network in the orbitofrontal cortex found that this method can effectively regulate the choice behavior guided by reward rather than punishment.

The study found that 5 days of chronic stimulation can reduce compulsive behavior for 3 months, and subjects with the most severe symptoms improved the most.

  The author of the paper believes that the research results show that this new personalized brain regulation may bring long-term benefits to patients suffering from behaviors such as forced eating, gambling, and shopping.
