Anticholinergic drugs linked to mental impairment in elderly people
Anticholinergic drugs may lead to mild cognitive (mental) impairment in elderly people, finds a study published online by the BMJ today. These drugs are commonly used in elderly patients to treat illnesses such as irritable bowel syndrome, urinary incontinence, and Parkinson's disease, so it is important that doctors are aware of this effect, say the researchers.

Motivation explains disconnect between testing and real-life functioning for seniors
A psychology researcher at North Carolina State University is proposing a new theory to explain why older adults show declining cognitive ability with age, but don't necessarily show declines in the workplace or daily life. One key appears to be how motivated older adults are to maintain focus on cognitive tasks. (2014-07-28)

Folic acid supplementation may improve cognitive performance
Folic acid supplementation may substantially improve cognitive function for older adults, according to an article in this week's Lancet. (2007-01-18)

Menstruation doesn't change how your brain works -- period
It has long been assumed that your period affects your brain's performance. Professor Brigitte Leeners and her team studied a sample of women in Zürich and Hannover to determine whether changes in hormones during the menstrual cycle really do change how well brains work. By increasing the sample size and following participants over more than one menstrual cycle, they found evidence that your brain's performance isn't affected by your cycle. (2017-07-04)

Animal behaviour: Cognitive performance of four-months-old ravens may parallel adult apes

USC study finds warmer temperatures improve women's performance
A new USC study found that women performed better on math and verbal tasks at higher temperatures, while the opposite was true for men.

Lumosity presents 99,022-participant study on learning rates at Neuroscience 2014
The study, titled 'Optimizing Cognitive Task Designs to Improve Learning Rates in a Large Online Population,' analyzed game play performance from 99,022 participants, and found that participants operating closer to their performance threshold earlier in their experience with a cognitive task tend to have faster learning rates -- especially at higher levels of difficulty. (2014-11-18)

Manipulating brain network to change cognitive functions: New breakthrough in neuroscience
When an electric circuit breaks down, we can repair it by restoring connections in the circuit. Is it possible to restore the connections in our brain? And by doing so, is it possible to restore declining cognitive functions? Numerous regions of the brain are connected together and constitute a huge network. Researchers have developed a learning method to change cognitive function by manipulating connections in the brain. (2017-08-07)

Late, but not too late -- screening for olfactory dysfunction
In a large population-based study of randomly selected participants in Germany, researchers found that participants aged 65-74 years with olfactory dysfunction showed impaired cognitive performance. Interestingly, this strong association was not present in younger (55-64 years) or older (75-86 years) participants. Additionally, the effect was more present in women than men. (2018-04-20)

Increased fluctuation in blood pressure linked to impaired cognitive function in older people
Higher variability in visit-to-visit blood pressure readings, independent of average blood pressure, could be related to impaired cognitive function in old age in those already at high risk of cardiovascular disease, suggests a paper published today on bmj.com. (2013-07-30)

Older brains slow due to greater experience, rather than cognitive decline
What happens to our cognitive abilities as we age? Traditionally it is thought that age leads to a steady deterioration of brain function, but new research in Topics in Cognitive Science argues that older brains may take longer to process ever increasing amounts of knowledge, and this has often been misidentified as declining capacity. (2014-01-21)

Chimpanzee intelligence depends on genes
Some chimpanzees are smarter than others, and about half of that variation in intelligence depends on the genes that individuals carry and pass on from one generation to the next. The findings reported in the Cell Press journal Current Biology on July 10 show that those genetic differences will be key to understanding the cognitive abilities of primates and their evolution over time. (2014-07-10)
