A New Treatment for Alzheimer's? A drug commonly used to treat arthritis caused a dramatic and rapid improvement in patients with Alzheimer’s disease, according to physicians in California. However, scientists and others not involved in the work worry that the report, which was based on trials in a few patients and hasn’t been independently confirmed, may offer little more than false hope for Alzheimer’s sufferers and their families. Alzheimer’s patients injected with the anti-inflammatory drug etanercept–marketed as Enbrel–showed dramatic improvements in their functioning within minutes, according to Edward Tobinick, director of the Institute for Neurological Research, a private medical facility in Los Angeles where the patients were treated, and an assistant clinical professor of medicine at the University of California, Los Angeles. “The patients improve literally before your eyes,” says Tobinick, who began using etanercept in Alzheimer’s patients three years ago.
Average IQ in US and 80 other nations The average IQ in the United States is usually set at 100. Groups within the US score different average IQ's, such as 115 for college grads or 85 for African-Americans. Similarly, average IQ varies from country to country, shown in the 2002 book IQ and the Wealth of Nations (sets Britain at 100): The top 5 nations above were also the top scorers (different order) in 8th grade math and science in 2003.

Comments by a reviewer: "This brilliantly conceived, superbly-written, path-breaking book, does for the global study of economic prosperity what Herrnstein and Murray's (1994) The Bell Curve did for the USA.
Mind-to-mind thought talking possible by 2030, scientist says Today we enjoy basic conversations with our smart phone, desktop PC, games console, TV and soon, our car; but voice recognition, many believe, should not be viewed as an endgame technology. Although directing electronics with voice and gestures may be considered state-of-the-art today, we will soon be controlling entertainment and communications equipment not by talking or waving; but just by thinking! Forget Siri, if future-thinking researchers have their way, your brain could soon be chatting away on the phone. Enter University of Reading's Dr. In 1998, Warwick implanted a transmitter in his arm enabling him to control doors and other devices. Next, Warwick implanted a chip in his wife Irena's arm, linking their brains together through the Internet. The goal of much of this research is to help patients rendered voiceless by strokes or other ailments speak their thoughts directly, much like Stephen Hawking, the famed physicist who speaks only with the aid of a computer synthesizer.
First Alzheimer’s Treatment to Fully Restore Memory Functionality As anyone who has seen what Alzheimer’s can do to a person will tell you, it’s not pretty, it’s not fun and it’s one of the most difficult diseases to deal with for both parties. It’s difficult to watch those you love grow older, but when they begin forgetting everything and everyone around them it can be just as damaging to those around them. What makes this disease such a problem is that there have been no significant advances in curing it or reversing its effects since the initial discovery in 1906. The scientists and researchers from the Queensland Brain Institute at the University of Queensland have been working diligently to discover something that would help, and it appears they may have now found a viable treatment. To the best of our current knowledge about Alzheimer’s is that it’s brought on by the buildup of two different types of neural plaques – neurofibrillary clusters and amyloid plaques, both stemming from different proteins.
Low IQ & Conservative Beliefs Linked to Prejudice | Racism, Bias & Politics | Right-Wing and Left-Wing Ideology There's no gentle way to put it: People who give in to racism and prejudice may simply be dumb, according to a new study that is bound to stir public controversy. The research finds that children with low intelligence are more likely to hold prejudiced attitudes as adults. These findings point to a vicious cycle, according to lead researcher Gordon Hodson, a psychologist at Brock University in Ontario. Low-intelligence adults tend to gravitate toward socially conservative ideologies, the study found. Those ideologies, in turn, stress hierarchy and resistance to change, attitudes that can contribute to prejudice, Hodson wrote in an email to LiveScience. "Prejudice is extremely complex and multifaceted, making it critical that any factors contributing to bias are uncovered and understood," he said. Controversy ahead The findings combine three hot-button topics. Brains and bias As suspected, low intelligence in childhood corresponded with racism in adulthood. A study of averages

smart-drugs g factor (psychometrics) The g factor (short for "general factor") is a construct developed in psychometric investigations of cognitive abilities. It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the fact that an individual's performance at one type of cognitive task tends to be comparable to his or her performance at other kinds of cognitive tasks. The g factor typically accounts for 40 to 50 percent of the between-individual variance in IQ test performance, and IQ scores are frequently regarded as estimates of individuals' standing on the g factor. The terms IQ, general intelligence, general cognitive ability, general mental ability, or simply intelligence are often used interchangeably to refer to the common core shared by cognitive tests. The existence of the g factor was originally proposed by the English psychologist Charles Spearman in the early years of the 20th century. Mental tests may be designed to measure different aspects of cognition.
Alzheimer's Disease Fact Sheet Alzheimer’s disease is an irreversible, progressive brain disease that slowly destroys memory and thinking skills, and eventually even the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear after age 60. Estimates vary, but experts suggest that as many as 5.1 million Americans may have Alzheimer’s disease. Alzheimer’s disease is the most common cause of dementia among older people. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities, to such an extent that it interferes with a person’s daily life and activities. Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person’s functioning, to the most severe stage, when the person must depend completely on others for basic activities of daily living. Alzheimer’s disease is named after Dr. Changes in the Brain in Alzheimer’s Disease Very Early Signs and Symptoms Mild Alzheimer’s Disease What Causes Alzheimer’s
Mind-altering microbes: Probiotic bacteria may lessen anxiety and depression -- ScienceDaily Probiotic bacteria have the potential to alter brain neurochemistry and treat anxiety and depression-related disorders according to research published in the Proceedings of the National Academy of Sciences. The research, carried out by Dr Javier Bravo, and Professor John Cryan at the Alimentary Pharmabiotic Centre in University College Cork, along with collaborators from the Brain-Body Institute at McMaster University in Canada, demonstrated that mice fed with Lactobacillus rhamnosus JB-1 showed significantly fewer stress, anxiety and depression-related behaviours than those fed with just broth. Moreover, ingestion of the bacteria resulted in significantly lower levels of the stress-induced hormone, corticosterone. "This study identifies potential brain targets and a pathway through which certain gut organisms can alter mouse brain chemistry and behaviour.
Types of Intelligence-IQ, EQ,MQ,BQ Howard Gardner’s seven types of intelligence guide us in selecting child specific teaching methods and career. There are other types of intelligence which parents and teachers should develop in children, to prepare them to face the world independently. Earlier psychologists termed this as “Social intelligence”- the ability to get along with other people. Usually we feel that a child with a high IQ (Intelligence Quotient- measurement of intelligence) will have a bright future. But there are many examples in the real world where we find that people who had been average students are more succesful and happy with their life and career. This is because when a person enters the professional world independently, she/he is faced with myriad situations and people dealing which is not taught in regular school syllabus. What is Intelligence? Intelligence is the capacity of a person to understand, learn and apply knowledge. Emotional Intelligence Moral Intelligence Bodily Intelligence
Brain is not fully mature until 30s and 40s (PhysOrg.com) -- New research from the UK shows the brain continues to develop after childhood and puberty, and is not fully developed until people are well into their 30s and 40s. The findings contradict current theories that the brain matures much earlier. Professor Sarah-Jayne Blakemore, a neuroscientist with the Institute of Cognitive Neuroscience at University College London, said until around a decade ago many scientists had "pretty much assumed that the human brain stopped developing in early childhood," but recent research has found that many regions of the brain continue to develop for a long time afterwards. The prefrontal cortex is the region at the front of the brain just behind the forehead, and is an area of the brain that undergoes the longest period of development. Prof. In earlier research Professor Blakemore studied the brains of teenagers in detail, as reported in PhysOrg. Explore further: Study: Our brains compensate for aging
