Depression and anxiety linked to changes in the cerebral cortex

Chinese scientists have found that depression and anxiety are associated with structural changes in the human brain. Scientists will talk about their work at the annual convention of the Radiological Society of North America, which will be held from November 26 to December 1 in Chicago. Scientists were interested in two conditions: clinical depression (or major depressive disorder, MDD) […]

Psilocybin mushrooms have cured depression

Scientists at Imperial College London have found that psilocybin , a substance found in hallucinogenic mushrooms, alters the activity of neural circuits associated with mood. Research published in Scientific Reports . The study involved 19 people with chronic depression that did not respond to treatment. During the first week, the volunteers took 10 mg of psilocybin . Over the next seven days, participants took 25 mg of psilocybin . The […]

Found the cause of emotional callousness

The Russian physician found out that disturbances in the perception of emotions arise as a defensive reaction. A trait known as alexithymia helps a person avoid depressive disorders under stress. The study was published in the Journal of Psychosomatic Research . Alexithymia is a psychopathic trait, the characteristic features of which are that a person does not know how to recognize his own and other people’s emotions, […]

In Russia, collectivism intensifies depression

Russian researchers have shown that in Russia a person who puts public interests above their own is at risk of suffering from depression. The study, supported by a grant from the Russian Science Foundation (RSF), was published in the journal Personality and Individual Differences . It is known that individualism dominates in the developed Western countries, especially in the United States, and collectivism in East […]

Scientists have been able to turn mice into “Zen Buddhists”

Scientists from Stanford University and colleagues found a group of neurons in the brains of mice, the removal of which made the animals breathe more slowly and feel calmer. The research is published in the journal Science . Slow, controlled breathing has been used for centuries to calm the mind and maintain mental health. Breathing techniques are also used, for example, […]

The moon can really affect the mood of the mentally ill

Doctors described a case of a person with bipolar disorder, whose episodes of illness alternated in accordance with the movement of the moon. Its internal biological clock was set not only for a 24-hour solar day, but also for a period of 24.8 hours, during which the Moon makes one visible revolution in the celestial sphere. The […]

Maternal depression leads to a decrease in the child’s IQ

The child’s IQ was found to be related to the mental state of the mother. Depression in mothers slows down the development of the child and leads to the fact that the IQ of their children is below average. This is the conclusion reached by the authors of the study, which was described by the website EurekAlert . About 900 children […]

The immune system can protect against depression

American researchers have studied the cerebrospinal fluid of healthy people and people with multiple sclerosis. They concluded that immune cells may play a role not only in protecting against infections, but also in maintaining mental health. The work was published in the journal Science Immunology . Researchers at Yale University have found an inflammatory autoimmune response similar to that found in neurodegenerative diseases such as multiple sclerosis […]

A new method of prescribing antidepressants has been developed

The researchers found that measuring brain rhythms during REM sleep may reflect the effectiveness of antidepressant treatment. The discovery will allow to quickly select the right therapy for patients, and not to continue ineffective treatment for several weeks without knowing the result. The work was presented at the congress of the European College of Neuropsychopharmacology . About 7% of adults worldwide […]
