Checklist of possible behavioral warning signs of dementia

Speed of visual processing is a cognitive skill that declines with age, a trend that some neuroscientists attribute to the increasing "noise" in electrical communications between cells and among regions in the brain.

HIV remains to be a global problem with almost 37 million reported infections around the world in 2014, this include approximately 2 million new cases of HIV infection that year.

The findings were presented at the annual Alzheimer's Association International Conference, held from July 22 to 28 in Toronto.

King said the training offered in the program was slightly different from the current Posit Science offering and that it was unclear whether speed training would help people who are already at risk for dementia.

The subjects underwent brain training in an initial series of ten group sessions, with a smaller group also receiving four-session booster trainings at one and three years after enrolment.

The study involved almost 3,000 healthy older people who were randomly assigned to take a five week classroom-based training that involved either improving their processing speed, improving their memory skills, or improving their reasoning skills, and followed over 10 years.

The third study provided results from a 10-year clinical trial involving nearly 2,800 people sorted into one of three different brain training groups.

Following a massive review of the literature, the Alzheimer's Association previous year produced a list called "10 Way To Love Your Brain" to highlight preventative measures.

Simple eye and smell tests could be used to spot dementia years before sufferers experience memory symptoms, new research suggests.

The results aren't surprising: experts have said that being socially active and mentally engaged, in work and in your personal life, are key to keeping your brain happy.

In the second part to the study, the scientists looked at 282 people with an average age of 60, who were at an early stage of dementia.

"If this was a drug, it'd be worth tens of billions of dollars and prescribed to just about every person in the universe", Mr. Merzenich asserted.

The specific exercise tested was the "Double Decision" game, one of several brain games marketed by the San Francisco-based Posit Science Corp, the Times said. These also include the so-called "brain games".

"I believe we do require something similar to this", stated Nina Silverberg, the representative of the Alzheimer's Illness Facilities plan in the National Institute on Aging, who had been not involved with making even the new analysis or the record.

As to how such a challenge could have long-enduring effects benefiting brain power, Mr. Merzenich said it has a strong effect on release of acetylcholine, an important neurotransmitter in the brain.

The third study, a brain exercise that took place over ten years, showed some success in decreasing the risks for dementia, but only for brain-training that worked on quick thinking under pressure.

With such training, he said, "it means you have substantially higher levels of stimulation, and you're going to be more engaged".

New research from the Wisconsin Registry for Alzheimer's Prevention (WRAP) and the Wisconsin Alzheimer's Disease Research Center (ADRC) shows that people whose jobs involve complex interactions with other people fare the best as their brains age. This research provides the first evidence that computer-based brain training - in this case which improves the speed that your brain can process information - could reduce the likelihood of developing dementia over a decade. After five years of the ACTIVE study, participants in the group performed better on what are known as instrumental activities of daily living, such as managing a checkbook and maintaining a neat household.
