Drinking Four Glasses of Wine a Week Can Raise the Risk of Dementia

A new study, conducted by researchers from King’s College London, suggests that drinking just four pints of beer or small glasses of wine a week increases the risk of developing dementia.Drinking Four Glasses of Wine a Week Can Raise the Risk of Dementia

For their research, a team of scientists analyzed data on over 15,000 people aged 50 and over and tracked them for 2 subsequent years. They examined the levels of alcohol they consumed, as well as quantity and frequency. Specialized tests were used to measure thinking skills.

Dr. Tony Rao, a consultant psychiatrist who led the study at King’s College London, says: “With a career of more than 20 years devoted to research on alcohol and older people, this is certainly the most groundbreaking study on the relationship between drinking and the risk of dementia. None of the participants had dementia at the start of the study but those who drank at risky levels were more likely to show a cognitive decline, which is likely to progress to dementia.”

Study: Eating Fish Regularly May Protect Brain Health

In a new study, a team of researchers from the University of Bordeaux in France found that higher fish intake is associated with lower levels of markers for vascular brain damage in senior adults, especially in the age between 65 and 74, without previous history of cognitive decline or cardiovascular diseases.Study Eating Fish Regularly May Protect Brain Health

For the current study, the scientists analyzed data collected between March 1999 and March 2001 for the Three-City Study. The analysis included 1,623 people, whose average age was 72.3 years. They all lived in Dijon, France. Those who had a dementia diagnosis, a history of stroke, or hospitalization for cardiovascular diseases, were excluded from the study.

The study’s senior author, Dr. Cecilia Samieri a senior researcher at the University of Bordeaux in France, explains: “Our results are exciting because they show something as simple as eating two or more servings of fish each week is associated with fewer brain lesions and other markers of vascular brain damage, long before obvious signs of dementia appear. However, eating that much fish did not have a protective effect in people 75 years of age and older.”

Study: Simple Diet May Protect Against Alzheimer’s Disease

In a new long-term study, researchers from Rush University in Illinois found that such a simple diet as the MIND diet can change the cognitive resilience to dementia in the future.Study Simple Diet May Protect Against Alzheimer's Disease

The MIND diet is based on the Mediterranean diet and the DASH (Dietary Approaches to Stop Hypertension) diet and was developed by nutritional epidemiologists at the mentioned university.

For this study, a team of scientists analyzed data on 569 participants who had died during a long-term study started in 1997, called the Memory and Aging Project. All participants agreed to undergo yearly clinical evaluations while they were alive, and an autopsy after death.

Geriatric health researcher Klodian Dhana from Rush Medical College says: “Some people have enough plaques and tangles in their brains to have a postmortem diagnosis of Alzheimer’s disease, but they do not develop clinical dementia in their lifetime. Some have the ability to maintain cognitive function despite the accumulation of these pathologies in the brain, and our study suggests that the MIND diet is associated with better cognitive functions independently of brain pathologies related to Alzheimer’s disease.”

Depression in Early Adulthood Increases the Risk of Developing Dementia

A new study, conducted by researchers from the University of California, San Francisco, suggests that people suffering from depression in early adulthood have a higher risk to develop dementia later in life.Depression in Early Adulthood Increases the Risk of Developing Dementia

For the study, the researchers analyzed data received from more than 15,000 participants, aged between 20 and 89, who were at different stages of their life. The analysis showed that individuals who had symptoms of depression in their 20s had an almost 75% higher risk to experience full cognitive decline when they become old.

Lead study author Dr. Willa Brenowitz, from the UCSF Department of Psychiatry and Behavioral Science, says: “Generally, we found that the greater the depressive symptoms, the lower the cognition and the faster the rates of decline. Older adults estimated to have moderate or high depressive symptoms in early adulthood were found to experience a drop in cognition over 10 years.”

Tooth Loss Linked to Increased Risk of Cognitive Decline and Dementia

In a new study, published in JAMDA: The Journal of Post-Acute and Long-Term Care Medicine, researchers found a link between tooth loss and an increased risk of cognitive decline and dementia.Tooth Loss Linked to Increased Risk of Cognitive Decline and Dementia

For the study, a team of scientists searched six databases for longitudinal studies and completed a meta-analysis that covered 34,074 participants, of whom 4,689 had some form of diminished cognitive functioning.

The analysis showed that tooth loss was associated with 1.48 times greater risk of cognitive decline and a 1.28 times risk of dementia. Moreover, for every tooth lost, a person had a 1.1% higher risk of developing dementia and a 1.4% higher risk of having a cognitive decline.

Prof. Bei Wu, dean’s professor in Global Health at New York University (NYU) Rory Meyers College of Nursing, co-director of the NYU Aging Incubator, and the study’s senior author, says: “Given the staggering number of people diagnosed with Alzheimer’s disease and dementia each year and the opportunity to improve oral health across the lifespan, it’s important to gain a deeper understanding of the connection between poor oral health and cognitive decline.”
