Body #mass index, diet, physical inactivity, and the incidence of #dementia in 1 million UK women

..Fifteen years after the baseline survey, only 1% were lost to follow-up, and 89% remained alive with no detected dementia, of whom 18,695 had dementia detected later, at a mean age of 77 (SD 4) years. Dementia detection during years 15+ was associated with baseline obesity (BMI 30+ vs 20–24 kg/m2: RR 1.21, 95% confidence interval 1.16–1.26, p < 0.0001) but not clearly with low … Continue reading Body #mass index, diet, physical inactivity, and the incidence of #dementia in 1 million UK women

Are symptoms of #insomnia in primary care associated with subsequent onset of #dementia? A matched retrospective case-control study

..We investigated the association between dementia diagnosis and recording of insomnia symptoms 5–10 years earlier in primary care. ..We ascertained the presence of insomnia symptoms during a five-year period starting 10 years before the index date. Odds ratios for developing dementia were estimated using logistic regression after controlling for hypnotic exposure and physical and mental health comorbidities. Results: The adjusted odds ratio for dementia in those with … Continue reading Are symptoms of #insomnia in primary care associated with subsequent onset of #dementia? A matched retrospective case-control study

#Illiteracy, #dementia risk, and cognitive trajectories among older adults with low education

..Analyses included 983 adults (≥65 years old, ≤4 years of schooling) who participated in a longitudinal community aging study. Literacy was self-reported (“Did you ever learn to read or write?”).. ..Illiterate participants were almost 3 times as likely to have dementia at baseline compared to literate participants. Among those who did not have dementia at baseline, illiterate participants were twice as likely to develop dementia. … Continue reading #Illiteracy, #dementia risk, and cognitive trajectories among older adults with low education

#Particulate matter and episodic #memory decline mediated by early neuroanatomic biomarkers of Alzheimer’s disease

Evidence suggests exposure to particulate matter with aerodynamic diameter <2.5 μm (PM2.5) may increase the risk for Alzheimer’s disease and related dementias.. ..Long-term PM2.5 exposure was associated with increased Alzheimer’s disease pattern similarity scores, which accounted for 22.6% (95% CI: 1% to 68.9%) and 10.7% (95% CI: 1.0% to 30.3%) of the total adverse PM2.5 effects on Trials 1–3 and List B, respectively. The observed … Continue reading #Particulate matter and episodic #memory decline mediated by early neuroanatomic biomarkers of Alzheimer’s disease

#Antihypertensive medications and risk for incident #dementia and #Alzheimer’s disease: a meta-analysis of individual participant data from prospective cohort studies

..We assessed the association of incident dementia and clinical Alzheimer’s disease with use of five AHM classes, within strata of baseline high (systolic blood pressure [SBP] ≥140 mm Hg or diastolic blood pressure [DBP] ≥90 mm Hg) and normal (SBP <140 mm Hg and DBP <90 mm Hg) blood pressure. ..There were 3728 incident cases of dementia and 1741 incident Alzheimer’s disease diagnoses. In the … Continue reading #Antihypertensive medications and risk for incident #dementia and #Alzheimer’s disease: a meta-analysis of individual participant data from prospective cohort studies

Intact global #cognitive and #olfactory ability predicts lack of transition to #dementia

Odor identification deficits characterize Alzheimer’s disease and other dementias ..Smell Identification Test, which includes the 12-item Brief Smell Identification Test (B-SIT) ..In covariate-adjusted survival analyses, impairment on the Blessed Orientation Memory Concentration Test and B-SIT each predicted dementia (n = 109), primarily Alzheimer’s disease (n = 101). Among participants with intact olfactory (B-SIT ≥ 11/12 correct) and cognitive (Blessed Orientation Memory Concentration Test ≤ 5/28 … Continue reading Intact global #cognitive and #olfactory ability predicts lack of transition to #dementia

Serum elaidic acid concentration and risk of #dementia. The Hisayama study

The associations between #trans fatty acids and dementia have been unclear. We investigated the prospective association between serum elaidic acid (trans 18:1 n-9) levels, as an objective biomarker for industrial trans fat, and incident dementia and its subtypes. Higher serum elaidic acid levels were significantly associated with greater risk of developing all-cause dementia (p for trend = 0.003) and AD (p for trend = 0.02) … Continue reading Serum elaidic acid concentration and risk of #dementia.

Association Between High School #Personality Phenotype and #Dementia 54 Years Later in Results From a National US Sample

To examine whether personality during adolescence—a time when preclinical dementia pathology is unlikely to be present—confers risk of dementia in later life and to test whether associations could be accounted for by health factors in adolescence or differed across socioeconomic status (SES). Lower risk of dementia was associated with higher levels of vigor (hazard ratio for 1 SD, 0.93; 95% CI, 0.90-0.97; P < .001). Calm and … Continue reading Association Between High School #Personality Phenotype and #Dementia 54 Years Later in Results From a National US Sample

Alcohol Consumption and Risk of Dementia and Cognitive Decline Among Older Adults With or Without Mild Cognitive Impairment

Findings were consistent when stratified by sex, age, and APOE E4 genotype. Compared with drinking less than 1.0 drink per week, complete abstention (in participants without MCI) and the consumption of more than 14.0 drinks per week (in participants with MCI) were associated with lower Modified Mini-Mental State Examination scores (mean difference at follow-up compared with baseline, −0.46 point [95% CI, −0.87 to −0.04 point] … Continue reading Alcohol Consumption and Risk of Dementia and Cognitive Decline Among Older Adults With or Without Mild Cognitive Impairment
