JAMA psych: 82000 people over 50 years of research results. Personality in adolescence may be related to the risk of dementia in later life

October 19, 2019 / BIOON / -- can a person's personality in youth predict the risk of dementia 50 years later? Recently, in a research report published in the international journal JAMA psychiatry, scientists from institutions such as the University of Rochester found that those calm, mature and energetic high school students tend to have a lower risk of dementia in later stage Image source: Kelly, researcher, mediaexpress.com Staying calm and mature in adolescence is directly related to a 10% reduction in the risk of dementia in adulthood, according to Peters The findings come from the 1960s, when researchers conducted a personality test on about 1200 82000 high school students in the United States More than 50 years later, researchers conducted a correlation study between the personality characteristics of these participants and the diagnosis of dementia A large amount of research evidence shows that personality changes before and after individuals are diagnosed with dementia Researchers do not know whether personality or personality problems really lead to dementia? In this study, the average age of participants was 16 years old, and the researchers assessed 10 characteristics, including calmness, vitality, organization, self-confidence, maturity / responsibility, leadership, impulse, desire for social interaction, social sensitivity, and artistic and intellectual well-being; between 2011 and 2013, when the age of participants was about 70 years old, more than 2500 people suffered from dementia Dementia When the researchers compared the personality characteristics of the participants at the age of 50 with their medical records, they found that those who were calm, energetic and mature had significantly lower risk of dementia in the later stage; calm was defined as no pressure or less pressure (no neuroticism), while energetic meant that they were energetic and outgoing, while mature meant that individuals were stable, responsible Reliable The researchers analyzed only protective features, but calmness, energy and maturity did not seem to reduce the risk of dementia in adolescents growing up in relatively poor families In addition, the researchers also tracked dementia patients around the age of 70 The average age of Alzheimer's patients is about 80 years old In the future, the researchers hope to continue in-depth research to see what happens when the patients have the highest risk of dementia Although researchers have now elucidated the link between dementia and personality, they don't know the exact link Including society, environment and heredity Many factors, including factors, will increase the risk of dementia Researchers need to further study to clarify the mechanism of dementia caused by these factors and the interaction between them At present, there is not enough evidence to show that the intervention in high school is effective The researchers remind you not to evaluate the personality / character of a person based on the results of this study In contrast, impulsivity and neuroticism, while increasing the risk of dementia, bring other skills to these people 'we don't want all children to be calm at all times, we don't want everyone to fit this pattern, and we have to be very careful to explain these findings before we really understand what they mean,' said researcher porsteinsson Original source: Chapman BP, Huang A, Peters K, et al Association between high school personality phenotype and dementia 54 years later in results from a national US sample JAMA psychiatry 2019 OCT 16 Doi: 10.1001/jamapsychiatry.2019.3120
