The typical rise and fall of alcohol and cannabis consumption from late adolescence into adulthood does not hold for people with certain personality traits, a new study suggests. Among individuals who used both alcohol and cannabis, those with high impulsivity as adolescents showed a different developmental trajectory from their peers, according to a study in Alcoholism: Clinical & Experimental Research — the first to assess co-use of the two substances well into adulthood. Alcohol and cannabis are the two most frequently used psychotropic drugs in the US. High use is associated with negative health outcomes, particularly when the two substances are used concurrently or simultaneously. Little is known about the developmental course of alcohol and cannabis co-use into adulthood and whether it is influenced by sensation seeking and reduced conscientiousness, markers of disinhibition associated with hazardous substance use. Researchers at Arizona State University explored whether those pe
A study, published in the Proceedings of the National Academy of Sciences, sampled more than 1.5 million people in 269 U.S. counties and 37 European nations. Researchers found that those who grew up in areas with higher levels of atmospheric lead had less adaptive personalities in adulthood — lower levels of conscientiousness and agreeableness and higher levels of neuroticism.
New research from the Florida State University College of Medicine has found that the personality trait neuroticism is consistently associated with a higher risk of developing the brain disorder Parkinson’s disease.
The research by Professor of Geriatrics Antonio Terracciano and team, published in Movement Disorders, found that adults in the study who scored in the top quartile of neuroticism had more than 80% greater risk of Parkinson’s, compared to those who scored lower on neuroticism.
College students are under a lot of stress, even more so lately due to the COVID-19 pandemic. Based on certain personality types, especially neurotic personalities, college health courses could help students develop a more positive stress mindset, according to research from faculty at Binghamton University, State University of New York.
