Scientists have studied the so-called infectious itchy skin, which is transmitted visually.
According to dermatologist Gil Ezipovicha who participated in the study, it is possible that the mechanisms underlying this phenomenon may be similar to those of infectious yawning - a phenomenon that is still intensely studied, but still not fully understood.
The study involved 14 healthy people and 11 people with atopic der
Study participants received either histamine - a substance that causes itching, or saline.Histamine was applied to the intact skin of patients with atopic dermatitom.Ispytuemye viewed short video clips in which people or scratched, or are in a relaxed state.After that, scientists have conducted a thorough analysis of their behavior.
In people with atopic dermatitis, as well as the participants of the experiment with inflammatory diseases of the skin, observed more intense itching when watching video, which characters were scratched.Furthermore, they were scratched longer and in more places than healthy study participants.
Dr. Alexander Papo says that watching people itchy affects the human cerebral cortex, which is very susceptible to pruritus, and easily causes a response in the central nervous system.
understand what is happening in our brain, we can develop ways to treat, acting directly on the data area of the brain, and thus do away with pulses of pruritus.
Scientists emphasize that this study is an early and observant character.In the future we plan to conduct magnetic resonance imaging to study the mechanisms that trigger itching.
Their goal - to develop certain technologies, such as relaxation and meditation, in addition to medication.These therapies will impact directly on the desired areas of the brain and reduce the severity of urgency for carding.
results of the study were published in the journal British Journal of Dermatology.
