Researchers from the United States found out that the presence of the interlocutor slows down the reduction of intellectual abilities in old age. The work of scientists is published in Jama Network Open.
Scientists have established that if there are people who are ready to listen to it if necessary, then it increases cognitive stability – the brain ability measure is better than expected in one or another age.
Researchers from New York University analyzed data on 2171 people. The average age of the research participants amounted to 63 years. They preserved information about the frequency of social contacts, interactions with close people. Cognitive stability Scientists have detected, correlated with MRI brain volume with neuropsychological tests with the cognitive abilities of a person with neuropsychological tests.
It turned out that those people had the greatest ratio of available cognitive functions with a brain volume. Scientists note that a further study of social interactions will better understand the mechanisms of the relationship of psychosocial factors with mental health.
