Release date: 2017-06-13 British researchers have recently reported that a drug commonly used to treat high blood pressure can make people more confident about their own judgments and behaviors. This finding may help develop new ways to treat obsessive-compulsive disorder and schizophrenia. According to the British "New Scientist" magazine website, researchers at the University College London in the United Kingdom tested the metacognitive function of the human brain and found that propranolol (also known as propranolol), which is commonly used to treat hypertension and arrhythmia, can be enhanced. Human confidence. Metacognition is the understanding and evaluation of people's own thoughts and behaviors, and is related to self-confidence. Patients with schizophrenia and obsessive-compulsive disorder are often accompanied by symptoms such as low self-confidence caused by abnormalities in metacognitive function. For example, patients with obsessive-compulsive disorder will go back and forth over and over again to check whether they have locked the door. People don't understand the specific mechanism of metacognition. It is generally thought to be related to two specific regions in the human brain. These two regions are regulated by dopamine and norepinephrine, and propranolol has the effect of inhibiting norepinephrine. . In the trial, the researchers gave different volunteers the drugs that inhibit dopamine, propranolol, and placebo, and then let them judge the direction of the light spots on the computer screen and ask them how confident they are in each judgment. The results showed that propranolol enhanced metacognition and allowed people to have a more accurate assessment of their performance in the test; drugs that inhibit dopamine and placebo did not. Researchers believe that elevated levels of norepinephrine may cause the brain to clear some of the near-term information, causing the brain to fail to extract sufficient information for decision-making reference, thereby reducing judgment. Propranolol helps increase confidence by inhibiting norepinephrine. In the future, researchers hope to further study whether propranolol affects other aspects of cognitive function, such as memory.
