Brain Training Games Reduce Dementia

Training your brain for reducing dementia development chances is the new mantra these days. There are so many games and websites now-a-days that boast their abilities in reducing individuals chances of developing memory loss or dementia. Its proven fact that regular reading, gaming and brain teasers help reduce the progress or atleast the speed of development of dementia. Now, researchers at the University of Cambridge have developed a game to train the brain that could help improve the memory of patients in the very earliest stages of dementia. This study has been published in "The International Journal of Neuropsychopharmacology".

Amnestic mild cognitive impairment (aMCI) has been described as the transitional stage between 'healthy ageing' and dementia. It is characterised by day-to-day memory difficulties and problems of motivation. At present, there are no approved drug treatments for the cognitive impairments of patients affected by the condition.

Cognitive training has shown some benefits, such as speed of attentional processing, for patients with aMCI, but training packages are typically repetitive and boring, affecting patients' motivation. To overcome this problem, researchers from the Departments of Psychiatry and Clinical Neurosciences and the Behavioural and Clinical Neuroscience Institute at the University of Cambridge developed 'Game Show', a memory game app, in collaboration with patients with aMCI, and tested its effects on cognition and motivation.

The researchers randomly assigned forty-two patients with amnestic MCI to either the cognitive training or control group. Participants in the cognitive training group played the memory game for a total of eight one-hour sessions over a four-week period; participants in the control group continued their clinic visits as usual.

In the game, which participants played on an iPad, the player takes part in a game show to win gold coins. In each round, they are challenged to associate different geometric patterns with different locations. Each correct answer allows the player to earn more coins. Rounds continue until completion or after six incorrect attempts are made. The better the player gets, the higher the number of geometric patterns presented - this helps tailor the difficulty of the game to the individual's performance to keep them motivated and engaged. A game show host encourages the player to maintain and progress beyond their last played level.

The results showed that patients who played the game made around a third fewer errors, needed fewer trials and improved their memory score by around 40%, showing that they had correctly remembered the locations of more information at the first attempt on a test of episodic memory. Episodic memory is important for day-to-day activities and is used, for example, when remembering where we left our keys in the house or where we parked our car in a multi-story car park. Compared to the control group, the cognitive training group also retained more complex visual information after training.

In addition, participants in the cognitive training group indicated that they enjoyed playing the game and were motivated to continue playing across the eight hours of cognitive training. Their confidence and subjective memory also increased with gameplay. The researchers say that this demonstrates that games can help maximise engagement with cognitive training.

"Good brain health is as important as good physical health. There's increasing evidence that training the brain can be beneficial for boosting cognition and brain health, but it needs to be based on sound research and developed with patients," says Professor Barbara Sahakian, co-inventor of the game: "It also need to be enjoyable enough to motivate users to keep to their programmes. Our game allowed us to individualise a patient's cognitive training programme and make it fun and enjoyable for them to use."

Dr George Savulich, the lead scientist on the study, adds: "Patients found the game interesting and engaging and felt motivated to keep training throughout the eight hours. We hope to extend these findings in future studies of healthy ageing and mild Alzheimer's disease."

The researchers hope to follow this published study up with a future large-scale study and to determine how long the cognitive improvements persist.

The design of 'Game Show' was based on published research from the Sahakian Laboratory at the University of Cambridge. The study was funded by Janssen Pharmaceuticals and Wellcome.

In 2015, Professor Sahakian and colleagues showed that another iPad game developed by her team was effective at improving the memory of patients with schizophrenia, helping them in their daily lives at work and living independently. The University of Cambridge Wizard memory game is available through PEAK via the App Store and Google Play.

Charging Implanted Heart Pumps Wirelessly

Mechanical pumps to give failing hearts a boost were originally developed as temporary measures for patients awaiting a heart transplant. But as the technology has improved, these ventricular assist devices commonly operate in patients for years, including in former vice-president Dick Cheney, whose implant this month celebrates its one-year anniversary. Prolonged use, however, has its own problems. The power cord that protrudes through the patient's belly is cumbersome and prone to infection over time. Infections occur in close to 40 percent of patients, are the leading cause of rehospitalization, and can be fatal. Researchers at the University of Washington and the University of Pittsburgh Medical Center have tested a wireless power system for ventricular assist devices. They recently presented the work in Washington, D.C. at the American Society for Artificial Internal Organs annual meeting, where it received the Willem Kolff/Donald B. Olsen Award for most promising research in

Autism and Eye Contact: Genes very much are involved

We have now a lot of evidence on genetic components in many disorders including neurological in both adults and kids. Autism is one such problem that has many genes involved. Research is still in full swing to find more genes and related pathways. However, one can find autistic features more phenotypically before genotyping. Eye contact is one of them. Studies have shown that autistic kids make less eye contact. This has been shown to have genetic component now. New research has uncovered compelling evidence that genetics plays a major role in how children look at the world and whether they have a preference for gazing at people's eyes and faces or at objects. The discovery by researchers at Washington University School of Medicine in St. Louis and Emory University School of Medicine in Atlanta adds new detail to understanding the causes of autism spectrum disorder. The results show that the moment-to-moment movements of children's eyes as they seek visual information about the

How much people depend on weather reports

Meteorologists on television, radio, online, and in newspapers supply weather reports to the average person over 100 times a month. Surveys demonstrated that the 300 billion forecasts accessed generate a value of $285 per household every year, or $32 billion for the entire United States. Odds are you have already watched one weather forecast today and will probably check out a few more. Accurate, timely forecasts are vital to everyday life, but just how critical may surprise you. Whether at work or play, you probably watch the weather quite closely. Most of us are at the weather person's mercy to know what to wear, what to expect, to prepare for the worst. New research shows the average United States household checks out a weather report more than three times a day. "It impacts pretty much every part of every activity we are involved with for the most part," Jeff Lazo, the director of the Societal Impacts Program at the National Center for Atmospheric Research (NCAR) in B
