A new study lead by the Neuroscience Institute of Alicante reveals how manipulating the endocannabinoid system can modulate high levels of impulsivity. This is the main problem in psychiatric illnesses such a schizophrenia, bipolar disorder and substance abuse. Spanish researchers have for the first time proved that the CB2 receptor, which has modulating functions in the nervous system, is involved in regulating impulsive behavior. "Such a result proves the relevance that manipulation...

Rarely researched gene plays important role in brain development, neuron functions Being impulsive can lead us to say things we regret, buy things we really don't need, engage in behaviors that are risky and even develop troublesome addictions. But are different kinds of hastiness and rashness embedded in our DNA? A new study suggests the answer is yes -- especially if you're a man. The research, led by University of Nebraska-Lincoln assistant professor of psychology Scott...

Impulsivity strongest predictor of obesity People with personality traits of high neuroticism and low conscientiousness are likely to go through cycles of gaining and losing weight throughout their lives, according to an examination of 50 years of data in a study published by the American Psychological Association. Impulsivity was the strongest predictor of who would be overweight, the researchers found. Study participants who scored in the top 10 percent on impulsivity weighed an average of...

Research finds connection between impulsivity and superstitions in pathological gamblers Research led by the University of Cambridge has found a link between impulsivity and flawed reasoning (such as believing in superstitious rituals and luck) in problem gamblers. Studying compulsive gamblers who were seeking treatment at the National Problem Gambling Clinic, the researchers found that those gamblers with higher levels of impulsivity were much more susceptible to errors in reasoning...

It seems that women become addicted to cocaine more easily than men and find it harder to give up. New research published in BioMed Central's open access journal Biology of Sex Differences reinforces this position by showing that the motivation of female rats to work for cocaine is much higher than males. Researchers from the Molecular and Behavioral Neuroscience Institute, University of Michigan, found that rats bred to have an elevated stress response and increased impulsiveness are more...

Disorganized and emotionally unstable, poorly adapted, suffering from alcohol problems, impulsive, or with a "globally adapted" personality. These are the features of the four diagnosed types of compulsive gamblers identified by researchers at the University Hospital of Bellvitge (IDIBELL) and the Autonomous University of Barcelona (UAB). According to the scientific team, only one of these four shows signs of a significant pathology. "We need to use different treatments for each sub-group of...

Previous studies have found that the personality trait impulsivity, or a lack of planning and forethought regarding behaviors, is associated with alcohol use and alcohol-use disorders. For most individuals, impulsivity decreases during emerging and young adulthood. Some, however, do not "mature out" of impulsivity. Now, University of Missouri researchers have found that individuals who exhibited the largest declines in impulsivity from ages 18-25 also exhibited the sharpest decreases in...

Study shows weak executive cognitive function not always to blame Conventional wisdom holds that adolescents are susceptible to drug use and other risk-taking behavior. However, a one-size-fits-all approach to curbing these behaviors likely will be unsuccessful, according to research to be presented Monday, May 3 at the Pediatric Academic Societies (PAS) annual meeting in Vancouver, British Columbia, Canada. Studies have suggested that increased risk-taking in adolescence may be due to late...

ADHD, or attention-deficit/hyperactivity disorder, is among the costliest of behavioral disorders. Its combination of inattention, impulsivity and hyperactivity leads to accidental injuries, school failure, substance abuse, antisocial behavior and more. Yet despite nearly a century of study, the disorder's roots remain mysterious. Much of modern ADHD research has focused on heritability of the condition, and indeed evidence suggests that genes may account for as much as 70 percent of...

Genetic predisposition to impulsivity is a trait predictive of alcoholism, U.S. researchers report. Nicholas Grahame of the Indiana University-Purdue University Indianapolis School of Science used selective breeding for 30 generations to produce mice that were high-volume alcohol drinkers and others that avoided consuming alcohol. The genetically different mice were presented with a choice between a small, immediate reward and a large, delayed reward. By adjusting the quantity of the...
