Half of young patients may outgrow bipolar disorder by age 30, U.S. researchers suggest. The Missouri University study, published in the Journal of Abnormal Psychology, was based on two large national surveys. Study co-author Kenneth Sher and colleagues say 5.5 percent to 6.2 percent of people between the ages of 18-24 suffer from bipolar disorder, but only about 3 percent of people older than 29 do. Young adults between the ages of 18-24 are going through significant life changes and social...

MU researchers find evidence that there may be developmentally limited forms of bipolar Bipolar disorder, or manic-depression, causes severe and unusual shifts in mood and energy, affecting a person's ability to perform everyday tasks. With symptoms often starting in early adulthood, bipolar disorder has been thought of traditionally as a lifelong disorder.  Now, University of Missouri researchers have found evidence that nearly half of those diagnosed between the ages of 18 and 25 may...

A new study explores how our brains synthesize concepts that allow us to organize and comprehend the world. The research, published by Cell Press in the September 24th issue of the journal Neuron, uses behavioral and neuroimaging techniques to track how conceptual knowledge emerges in the human brain and guides decision making. The ability to use prior knowledge when dealing with new situations is a defining characteristic of human intelligence. This is made possible through the use of...

 If you've ever felt doomed to repeat your mistakes, researchers at MIT's Picower Institute for Learning and Memory may have explained why: Brain cells may only learn from experience when we do something right and not when we fail.In the July 30 issue of the journal Neuron, Earl K. Miller, the Picower Professor of Neuroscience, and MIT colleagues Mark Histed and Anitha Pasupathy have created for the first time a unique snapshot of the learning process that shows how single cells change...

 Experiencing chronic stress day after day can produce wear and tear on the body physically and mentally, and can have a detrimental effect on learning and emotion. However, acute stress -- a short stressful incident -- may enhance learning and memory.Researchers at the University at Buffalo have shown, in trials using rodents as an animal model, that acute stress can produce a beneficial effect on learning and memory, through the effect of the stress hormone corticosterone (cortisol in...

Training increases brain processing speed and improves our ability to multitask, new research from Vanderbilt University published in the June 15 issue of Neuron indicates. "We found that a key limitation to efficient multitasking is the speed with which our prefrontal cortex processes information, and that this speed can be drastically increased through training and practice," Paul E. Dux, a former research fellow at Vanderbilt, and now a faculty member at the University of Queensland in...

Functional magnetic resonance imaging confirms the influences of peer, parents on self identityAsk middle-school students if they are popular or make friends easily, they likely will depend on social comparisons with their peers for an answer. Such reliance on the perceived opinions of others, or reflected self-appraisals, has long been assumed, but new evidence supporting this claim has now been found in the teen brain.Using functional magnetic resonance imaging (fMRI), researchers looked at...

A new study of the cognitive processes involved with honesty suggests that truthfulness depends more on absence of temptation than active resistance to temptation.Using neuroimaging, psychologists looked at the brain activity of people given the chance to gain money dishonestly by lying and found that honest people showed no additional neural activity when telling the truth, implying that extra cognitive processes were not necessary to choose honesty. However, those individuals who behaved...

Just as our world buzzes with distractions "” from phone calls to e-mails to tweets "” the neurons in our brain are bombarded with messages. Research has shown that when we pay attention, some of these neurons begin firing in unison, like a chorus rising above the noise. Now, a study in the May 29 issue of Science reveals the likely brain center that serves as the conductor of this neural chorus. MIT neuroscientists found that neurons in the prefrontal cortex "” the brain's...
