A neuroscientific study from the Downstate Medical Center of the State University of New York (USA) reveals thatintelligence and concernare related to choline deficiency in the subcortical white matter of the brain. The researchers conclude thatboth traits coevolvedin humans.
Worrying too much is usually considered a negative aspect of the personality, while intelligence is a quality that is valued positively. But the truth is that worry “can make our species avoid dangerous situations, no matter how remote they may seem,” underlines Jeremy Coplan, co-author of the work. And by not taking risks, people who are concerned are more likely to survive. “Therefore, as intelligence,worry brings us a benefit“Coplan adds.
In the studythe intelligence quotient (IQ) of patients with generalized anxiety disorder was measuredand it was compared with that of healthy volunteers. In those who suffered from anxiety,high IQ was associated with a higher level of concern. In healthy subjects, this did not happen.
The authors also found thatboth concern and intelligenceare characterized bya lack of choline and other related compoundsin the brain. Choline is one of the most abundant components contained in human brain tissues, and its presence is essential for the myelination of nerve tissues.
