Eight Habits That Improve Cognitive Function | Psychology Today Singapore The New York Times recently published an article about the "brain fitness" business, "Do Brain Workouts Work? Science Isn’t Sure." I believe the answer is no. Without a variety of other daily habits, these "brain-training" games cannot stave off mental decline or dramatically improve cognitive function. Most of these brain-training games will have some benefits, but it's impossible to optimize brain connectivity and maximize neurogenesis (growth of new neurons) sitting in a chair while playing a video game on a two-dimensional screen. In order to give your brain a full workout, you need to engage both hemispheres of the cerebrum, and of the cerebellum. article continues after advertisement Although the cerebellum constitutes only 10 percent of the brain by volume, it houses over 50 percent of the brain's total neurons.

6 simple steps to keep your mind sharp at any age Everyone has the occasional "senior moment." Maybe you've gone into the kitchen and can't remember why, or can't recall a familiar name during a conversation. Memory lapses can occur at any age, but aging alone is generally not a cause of cognitive decline. When significant memory loss occurs among older people, it is generally not due to aging but to organic disorders, brain injury, or neurological illness. Studies have shown that you can help prevent cognitive decline and reduce the risk of dementia with some basic good health habits: staying physically active getting enough sleep not smoking having good social connections limiting alcohol to no more than one drink a day eating a Mediterranean style diet. Memory and other cognitive changes can be frustrating, but the good news is that, thanks to decades of research, you can learn how to get your mind active. 1. A higher level of education is associated with better mental functioning in old age. 2. 3. 4. 5. 6.

How to reduce the risk of cognitive decline with age Research into how we can keep our brains healthy as we age has gained momentum in recent years. There is now an increased focus on the changes that we can makes to our health and lifestyle, which may prevent dementia. Here are some things that research has shown reduce a person’s risk of cognitive decline with age. Sex Our latest study shows that having more sex is associated with better cognitive function. We recruited 28 men and 45 women, aged between 50 and 83, to take part in our study. The association could be the result of the heightened levels of intimacy and companionship inherent in sexual relationships (that is, an increase in social contact), or there could be a purely biological explanation – where regular surges in arousal and release of sex-related hormones (such as oxytocin and dopamine) could be affecting brain function. Sleep Many studies show that getting enough sleep is important for preventing cognitive decline. Active leisure Gender equality Get an early (in life) start

Physical Activity and Risk of Cognitive Impairment and Dementia in Elderly Persons | Dementia and Cognitive Impairment | JAMA Neurology Context Dementia is common, costly, and highly age related. Little attention has been paid to the identification of modifiable lifestyle habits for its prevention. Objective To explore the association between physical activity and the risk of cognitive impairment and dementia. Design, Setting, and Subjects Data come from a community sample of 9008 randomly selected men and women 65 years or older, who were evaluated in the 1991-1992 Canadian Study of Health and Aging, a prospective cohort study of dementia. Main Outcome Measure Incident cognitive impairment and dementia by levels of physical activity at baseline. Results Compared with no exercise, physical activity was associated with lower risks of cognitive impairment, Alzheimer disease, and dementia of any type. Conclusion Regular physical activity could represent an important and potent protective factor for cognitive decline and dementia in elderly persons. Follow-up was carried out in 1996-1997 (CSHA-2).

The Impact of Age on Cognition Want to add more life to your years? Social connections ... When we’re young, we expect to live forever. It’s easy to stay focused on the present and avoid thinking about a reality that we all inevitably face – aging. But in our later years, we become aware of how everyday actions can contribute to a more fruitful life. Fostering social connections is one key to healthy aging, which is why Humana is sponsoring Active Aging Week, Oct. 1-7, a celebration of active living. The theme this year is “Redefining Active” which is designed to highlight how being active throughout the years means staying physically, emotionally and socially engaged. Studies have shown that more socially active older adults maintain their cognitive abilities for much longer than those who aren’t as social [1]. Movement and exercise Use it or lose it. Nutrition Curious about another way to boost time spent with others? Diet is certainly one component of healthy aging, but there’s more to nutrition than watching your salt intake or cholesterol.

Independent Predictors of Cognitive Decline in Healthy Elderly Persons | Dementia and Cognitive Impairment | JAMA Neurology Background Several studies have shown that individually memory, hippocampal volume, and motor measures presage the onset of dementia. It is unclear if these independently contribute to the prediction of mild cognitive impairment. Objective To determine the ability of memory, hippocampal volume, and a gait speed to independently predict cognitive decline in healthy elderly persons. Design A prospective, longitudinal, observational cohort study with a mean follow-up of 6 years. Participants One hundred eight optimally healthy elderly cognitively intact subjects. Main Outcome Measures Any cognitive impairment noted on the Clinical Dementia Rating Scale (score = 0.5) or persistent or progressive cognitive impairment. Results Questionable dementia occurred in 48 participants in a mean (SD) of 3.7 (2.4) years. Conclusions Models combining multiple risk factors should refine the prediction of questionable dementia and persistent cognitive impairment, harbingers of dementia.

How memory and thinking ability change with age Scientists used to think that brain connections developed at a rapid pace in the first few years of life, until you reached your mental peak in your early 20s. Your cognitive abilities would level off at around middle age, and then start to gradually decline. We now know this is not true. Instead, scientists now see the brain as continuously changing and developing across the entire life span. Some brain areas, including the hippocampus, shrink in size. On the other hand, the branching of dendrites increases, and connections between distant brain areas strengthen. Age is also the biggest risk factor for many brain diseases, most of which affect brain structure and function. As a result of these changes, you will likely start to notice slight slips in your memory in middle age and beyond. Short of a full neurological workup, there are ways to help identify the signs of more serious cognitive loss and determine when to call your doctor (see Table below).
