Air Pollution & Dementia
The Lancet Planetary Health has published a systematic review and meta-analysis of studies examining the association between air pollution and incident dementia. This review was intended to summarize all previous reviews, identify specific gaps in data, and incorporate new primary research. It included data from 32 studies and a pooled population of over 26 million…

Biological Age & Dementia
The results of a longitudinal prospective study evaluating the association between biological aging and dementia were recently published in Neurology, as well as evidence regarding changes in brain structures that may mediate any connection. The UK Biobank, a prospective longitudinal cohort with over half a million participants, was used to provide data for nearly 281,000…

Flavonoids & Dementia
The protective association between dietary flavonoid intake and the risk of dementia has been the focus of yet another study; this one being published recently in JAMA Network Open. Data from the UK Biobank, a prospective population-based cohort study, was analyzed not only to examine the relationship between flavonoids and all-cause dementia, but also to…

ADHD & Dementia
Using data from a prospective cohort study, an association was observed between adult-onset attention-deficit/hyperactivity disorder (ADHD) and an increased risk for dementia later in life, with an analysis recently published in JAMA Network Open. This association was generated using data from a prospective birth cohort comprised of individuals from Israel born between 1933 and 1952,…

Sleep & Dementia
The substantial associations between sleep and dementia continue to mount, with considerable evidence suggesting that deficits in sleep duration may be linked to a greater risk for dementia. Results of a large observational study recently published in Neurology indicate that sleep irregularity, independent of duration, may also be a risk factor.

Acid Suppression & Dementia
Recently published in Neurology is an analysis of the relationship between incident dementia and proton pump inhibitor (PPI) use among participants in the Atherosclerosis Risk in Communities (ARIC) Study, a community-based cohort. The possible association between PPI use and dementia has been examined in a number of case-control and cohort studies, with mixed findings. For…

Coffee & Tea Linked to Lower Stroke/Dementia Risk
In recently published data from the ongoing UK Biobank study, a population based cohort, greater consumption of coffee and tea were both linked to a lower risk for stroke, dementia, and post-stroke dementia. Over 365,000 participants aged 50-74 had data available regarding their beverage consumption, and over a median follow-up of 11.35 years, 2.8% had…

Prediabetes a Risk for Cognitive Decline and Dementia
Results from the UK Biobank study, one of the largest cohorts of middle-aged adults to provide data for HbA1c across the glycemic spectrum as well as measures of cognitive function, neuroimaging, and dementia, were recently published in the journal Diabetes, Obesity & Metabolism. The authors report that both prediabetes and diabetes were associated with an…
