Older age at retirement is associated with reduced risk of dementia – Some research has suggested that intellectual stimulation and mental engagement throughout life may be protective against Alzheimer’s disease and other dementias. In a new study, researchers found that retirement at older age is associated with a reduced risk of dementia.
Does being a bookworm boost your brainpower in old age? – New research suggests that reading books, writing and participating in brain-stimulating activities at any age may preserve memory. “Our study suggests that exercising your brain by taking part in activities such as these across a person’s lifetime, from childhood through old age, is important for brain health in old age,” said study author Robert S. Wilson, PhD, with Rush University Medical Center in Chicago.
Cholesterol increases risk of Alzheimer’s and heart disease – High levels of blood cholesterol increase the risk of both Alzheimer’s disease and heart disease, but it has been unclear exactly how cholesterol damages the brain to promote Alzheimer’s disease and blood vessels to promote atherosclerosis.
NIH-supported study finds U.S. dementia care costs as high as $215 billion in 2010 — Formal and unpaid dementia care costs are tallied – The costs of caring for people with dementia in the United States in 2010 were between $159 billion to $215 billion, and those costs could rise dramatically with the increase in the numbers of older people in coming decades, according to estimates by researchers at RAND Corp. and the University of Michigan, Ann Arbor.
Clogged heart arteries can foreshadow stroke — American Heart Association Rapid Access Journal Report – Blockages in your heart arteries could mean you’re more likely to have a stroke, even if you’re considered low risk. A new study raises the need for intensified interdisciplinary efforts for providing adequate disease prevention and management strategies for stroke.
Chewing ability linked to reduced dementia risk — Can you bite into an apple? If so, you are more likely to maintain mental abilities. – Can you bite into an apple? If so, you are more likely to maintain mental abilities, according to new research from Karolinska Institutet. The population is ageing, and the older we become the more likely it is that we risk deterioration of our cognitive functions, such as memory, decision-making and problem solving.
‘Cafeteria diet’ hastens stroke risk — High-sugar, high-salt intake creates ‘a ticking time bomb of health problems’ – The fat- and sugar-rich Western diet leads to a lifetime of health problems, dramatically increasing the risk of stroke or death at a younger age,. Researchers found that a high-calorie, high-sugar, high-sodium diet nicknamed the ‘cafeteria diet’ induced most symptoms of metabolic syndrome ? a combination of high levels of cholesterol, blood sugar, blood pressure and obesity ? in rats after only two months.
Binge drinking increases the risk of cognitive decline in older adults – Researchers from the Peninsula College of Medicine and Dentistry (PCMD), University of Exeter, suggesting a link between binge drinking in older adults and the risk of developing dementia. The work is supported by the National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care in the South West Peninsula (NIHR PenCLAHRC).
Stress link to Alzheimer’s goes under the spotlight — A new ?1.5 million study to find role of stress in development of dementia and Alzheimer’s disease – Chronic stress is being investigated in a new Alzheimer’s Society funded research project as a risk factor for developing dementia. It is part of a ?1.5 million package of six grants being given by the charity fighting to find a cause, cure and way to prevent the disease.
Role of omega-3 in preventing cognitive decline in older people questioned — Elderly warned that taking fish oil pills ‘does not prevent brain decline’ – Older people who take omega-3 fish oil supplements are probably not reducing their chances of losing cognitive function. Based on the available data from studies lasting up to 3.5 years, the researchers concluded that the supplements offered no benefits for cognitive health over placebo capsules or margarines, but that longer term effects are worth investigating.
