2 Drinks a Day Put Adults at a Higher Risk of Developing Dementia

If you drink nearly 14 drinks per week (2 drinks per day), you may be at a higher risk of developing dementia than those who enjoy drink a week

If you drink nearly 14 drinks per week (2 drinks per day) and already suffer from mild cognitive impairment (MCI), you may be at a higher risk of developing dementia than those who enjoy drink a week, say researchers.

According to researchers from Harvard University’s T.H. Chan School of Public Health, among those adults with MCI, the risk of dementia according to numbers of alcoholic drinks per week wasn’t statistically significant, although it appeared to be highest for drinking more than 14 drinks per week compared with less than one drink.

In this cohort study of 3,021 participants aged 72 years and older, alcohol intake within recommended limits was not significantly associated with a lower risk of dementia among participants with or without mild cognitive impairment at baseline.

Among participants without mild cognitive impairment, daily low-quantity drinking was associated with lower dementia risk compared with infrequent higher-quantity drinking.

“The findings suggest that physicians caring for older adults need to carefully assess the full dimensions of drinking behaviour and cognition when providing guidance to patients about their alcohol consumption,” said the research led by Manja Koch from T.H. Chan School of Public Health and published in the journal JAMA Network Open.

The study analyzed 3,021 adults (72 and older) who were free of dementia (2,548 were without MCI and 473 with MCI). During about six years of follow-up, there were 512 cases of dementia, including 348 cases of Alzheimer disease.

Among those adults without MCI, no amount of alcohol consumption was significantly associated with higher risk for dementia compared with drinking less than one drink per week.

Given the rapidly growing burden of Alzheimer disease (AD) and other dementias, including 50 million people currently living with dementia and 82 million expected by 2030, the identification of factors that prevent or delay the onset of dementia remains of paramount concern.

During the study, the participants reported their frequency of beer, wine, and liquor consumption in days per week and their usual number of 12-oz cans or bottles of beer, 6-oz glasses of wine, and shots of liquor consumed on each occasion.

“We categorized participants according to their alcohol consumption as follows: none, less than 1 drink per week, 1 to 7 drinks per week, 7.1 to 14 drinks per week, and more than 14 drinks per week,” the authors wrote.

In this study of older adults, the association of self-reported alcohol consumption with dementia risk appeared to cluster into 3 separate dimensions—baseline cognition, dose and pattern.

“At present, our findings cannot be directly translated into clinical recommendations, and these findings warrant additional studies to confirm these associations further,” the authors suggested. (IANS)

Physical illness And injury Raises The Risk of Suicide in Men, Not Women: Study

When it comes to identify who is more at suicide risk, scientists have found that physical illness and injury raises the risk of Suicide in Men but not women, along with a plethora of other insights into the complex factors that may increase a person’s risk of suicide.

The study, led by Boston University School of Public Health (BUSPH) and published in JAMA Psychiatry, is the first to use data from the population of an entire country (Denmark) and parse it with a Machine Learning (ML) system to identify suicide risk factors.

“Suicide is incredibly challenging to predict, because every suicide death is the result of multiple interacting risk factors in one’s life,” said lead study author Dr Jaimie Gradus, associate professor of epidemiology at BUSPH.

Dr Gradus and her colleagues looked at thousands of factors in the health histories of 14,103 individuals who died from suicide in the country from 1995 through 2015, and the health histories of 265,183 other Danes in the same period, using a machine-learning system to look for patterns.

Many of the study’s findings confirmed previously-identified risk factors, such as psychiatric disorders and related prescriptions.

The researchers also found new potential risk patterns, including that diagnoses and prescriptions four years before a suicide were more important to prediction than diagnoses and prescriptions six months before, and that physical health diagnoses were particularly important to men’s suicide prediction but not women’s.

“The findings of this study do not create a model for perfectly predicting suicide”, said Dr Gradus, in part because medical records rarely include the more immediate experiences — such as the loss of a job or relationship — that combine with these longer-term factors to precipitate suicide.

The findings, however, point to new factors to examine in working to prevent this persistent public health issue. (IANS)
