Men More Likely to Experience Memory Problems than Women

According to a recent research, mild cognitive impairment, which occurs with aging, is more common among men. People who experience mild cognitive impairment have problems with short-term memory and difficulty keeping conversations flowing. Several indicators include misplacing items or remembering what they want to say. The study used to compile the article concludes that men are 1.5 times more likely than women to experience mild cognitive impairment (MCI), which frequently leads to Alzheimer’s disease. Ronald Petersen, MD, Ph.D. from the Mayo Clinic was in charge of executing the study. Peterson and…

Feeling impulsive? High dopamine levels may be the cause

According to a study published in Journal of Neuroscience, high levels of dopamine make people more likely to act on impulse. Dopamine is the chemical in the brain involved with reward, motivation and learning through reinforcement. This finding may better explain disorders such as Attention Deficit/Hyperactivity Disorder (ADHD), which is characterized by high levels of dopamine and extremely impulsive behavior. Scientists already know that sensory inputs such as smells, sights, sounds, anticipation and neutral cues associated with rewards boost dopamine levels and cause people to act more impulsively. However, this research helps understand…

Study Concludes Attention-Deficit/Hyperactivity Disorder (ADHD) is Genetic

ADHD is a condition that affects children and adults across the globe. According to Healthcentral.com a classroom with 30 students will have between 1 and 3 children with ADHD, and one-fourth of children with ADHD have serious learning disabilities such as: oral expression, listening skills, reading comprehension and/or math. According to scientists at Cardiff University, children with ADHD are more likely to have segments of their DNA missing or duplicated. There is a clear genetic link between the same segments and other neurological disorders. The scientists analyzed the genomes of 366 children, all diagnosed…

New Study Provides Breakthrough in Addiction Treatments

Neuroscience

According to a study published in The Journal of Neuroscience, a memory-enhancing medication may help drug addicts avoid relapsing after therapy. Scientists have found that D-cycloserine, a chemical used to treat fear and anxiety disorders, may help a drug addict gain resistance. The study, led by Mary Torregrossa of Yale University, consisted of observing 168 rats that self-administered cocaine for weeks, a behavior identical to addiction in humans. The researchers used extinction therapy, a behavioral therapy, to minimize the craving effects of cues. They also added the D-cycloserine memory-enhancing drug to supplement…
