- In 2020, for the first time in history, there were more people in the world aged 60 years and over than there were children below the age of 5 years. The population aged over 65 years is projected to increase from one billion in 2019 to more than two billion in 2050, and those aged over 80 years are projected to increase from 143 to 426 million, with the largest increase occurring in the developing world (UN World Population Prospects, 2019). This demographic trend constitutes the largest global health challenge, according to the World Health Organisation (WHO). The European Union has set it as one of the major challenges in Horizon 2020 and it has important societal implications (European Commission, 2020). The proportion of retired individuals will increase, leading to an increased ratio between those who have exited the workforce and those still active in the labour market. Thus, ageing represents a global societal and scientific challenge requiring integrated efforts, multidisciplinary translational research approaches and social innovations that build on ideas of potentials and capabilities, emphasising the value of old age.

- ObjectivesTo evaluate birth cohort differences in level of cognition and rate of change in old age.MethodsData were drawn from three population-based Swedish samples including age-homogenous cohorts born 1901/02, 1906/07, and 1930, and measured on the same cognitive tests at ages 70, 75, and 79 as part of the Gerontological and Geriatric Populations Studies in Gothenburg (H70). We fitted growth curve models to the data using a Bayesian framework and derived estimates and inferences from the marginal posterior distributions.ResultsWe found moderate to large birth cohort effects in level of performance on all cognitive outcomes. Later born cohorts, however, showed steeper linear rate of decline on reasoning, spatial ability, and perceptual- and motor-speed, but not on picture recognition memory and verbal ability.DiscussionThese findings provide strong evidence for substantial birth cohort effects in cognition in older ages and emphasize the importance of life long environmental factors in shaping cognitive aging trajectories. Inferences from cognitive testing, and standardization of test scores, in elderly populations must take into account the substantial birth cohort differences. © The Author 2016.

- With aging, health deficits accumulate: people with few deficits for their age are fit, and those with more are frail. Despite recent reports of improved health in old age, how deficit accumulation is changing is not clear. Our objectives were to evaluate changes over 30 years in the degree of deficit accumulation and in the relationship between frailty and mortality in older adults. Methods: We analyzed data from two population based, prospective longitudinal cohorts, assembled in 1971–1972 and 2000–2001, respectively. Residents of Gothenburg Sweden, systematically drawn from the Swedish population registry. The 1901–1902 cohort (N = 973) had a response rate of 84.8%; the 1930 cohort (N = 500) had a response rate of 65.1%. A frailty index using 36 deficits was calculated using data from physical examinations, assessments of physical activity, daily, sensory and social function, and laboratory tests. We evaluated mortality over 12.5 years in relation to the frailty index. Results: Mean frailty levels were the same (x = 0.20, p = .37) in the 1901–1902 cohort as in the 1930 cohort. Although the frailty index was linked to the risk of death in both cohorts, the hazards ratio decreased from 1.67 per 0.1 increment in the frailty index for the first cohort to 1.32 for the second cohort (interaction term p = .005). Discussion: Although frailty was as common at age 70 as before, its lethality appears to be less. Just why this is so should be explored further.

- Although the use of antihypertensive medications has been associated with reduced risk of Alzheimer's disease (AD), it remains unclear which class provides the most benefit. The Cache County Study of Memory Health and Aging is a prospective longitudinal cohort study of dementing illnesses among the elderly population of Cache County, Utah. Using waves I to IV data of the Cache County Study, 3417 participants had a mean of 7.1 years of follow-up. Time-varying use of antihypertensive medications including different class of diuretics, angiotensin converting enzyme inhibitors, β-blockers, and calcium channel blockers was used to predict the incidence of AD using Cox proportional hazards analyses. During follow-up, 325 AD cases were ascertained with a total of 23,590 person-years. Use of any antihypertensive medication was associated with lower incidence of AD (adjusted hazard ratio [aHR], 0.77; 95% confidence interval [CI], 0.61-0.97). Among different classes of antihypertensive medications, thiazide (aHR, 0.7; 95% CI, 0.53-0.93), and potassium-sparing diuretics (aHR, 0.69; 95% CI, 0.48-0.99) were associated with the greatest reduction of AD risk. Thiazide and potassium-sparing diuretics were associated with decreased risk of AD. The inverse association of potassium-sparing diuretics confirms an earlier finding in this cohort, now with longer follow-up, and merits further investigation

Complement Gene Single Nucleotide Polymorphisms and Biomarker Endophenotypes of Alzheimer's Disease

- The complement system has been implicated in both physiological synapse elimination and Alzheimer's disease (AD). Here, we investigated associations between four single nucleotide polymorphisms (SNPs) in complement genes and cerebrospinal fluid (CSF) biomarkers for AD in 452 neurochemically or neuropathologically verified AD cases and 678 cognitively normal controls. None of the SNPs associated with risk of AD but there were potential associations of rs9332739 in the C2 gene and rs4151667 in the complement factor B gene with CSF tau levels (p = 0.023) and Mini-Mental State Examination scores (p = 0.012), both of which may be considered markers of disease intensity/severity.

- Objectives We examined the 1-month prevalence of obsessive-compulsive disorder (OCD) and obsessive-compulsive symptoms (OCS) not fulfilling OCD criteria in relation to sex, age, social and mental function, comorbid depression, and cognitive functioning in an elderly nondemented population. Settings and Participants Population-based sample (N = 900), stratified into two age groups: 70-year-olds (335 women and 224 men) and those aged 78 and above (341 women). Measurements Semi-structured interviews. Psychiatric symptoms were assessed with the Comprehensive Psychopathological Rating Scale and Mini-International Neuropsychiatric Interview, mental and social function with the GAF-scale, memory function with the Word Recall Task and general cognition with MMSE. OCD and Depression were diagnosed according to DSM-IV. Results The one-month prevalence of OCD was 2.9%; a further 21% had OCS. Among 70-year-olds, the prevalence of OCD was 1.3% in men and 4.5% in women. Depression was more common among those with OCD (34.6%) than among those with (12.7%) and without (8.0%) OCS. GAF-score was lower among those with OCD (74.8) and OCS (82.9) compared with individuals without obsessions and compulsions (88.2). The association between OCD and GAF-score remained after adjustment for age, sex, and depression. The OCD subgroup with checking behavior had more memory and concentration problems and did worse on Word Recall Task than other groups in our sample. Conclusions We found that OCD and OCS are common among the elderly. Both conditions are related to depression and poorer mental and social functioning. Physicians who meet elderly patients need to be aware of OCD as it is potentially treatable.

- BACKGROUND: Frontotemporal dementia (FTD) is believed to be rare in the elderly, and the influence of different criteria on the prevalence of FTD is unclear. METHODS: Population-based samples of 70- to 95-year-olds (n = 2462) in Gothenburg, Sweden, underwent neuropsychiatric examinations. Behavioral variant FTD (bvFTD) was diagnosed according to the International Behavioural Variant FTD Criteria Consortium (FTDC), the Frontotemporal Lobe Degeneration Consensus criteria, and the Lund-Manchester Research Criteria. A subset (n = 1074) underwent computerized tomography (CT) of the brain. RESULTS: The prevalence of bvFTD varied between 0.2% and 0.5% at age 70 to 79 years, between 2.5% and 3.6% at age 80 to 89 years, and between 1.7% and 2.2% at age 90 to 95 years. The agreement between different criteria was low to moderate (κ = 0.20-0.42). Among those with bvFTD according to FTDC, 93.3% had frontal and/or temporal lobar atrophy on CT, compared with 12.6% of those without bvFTD (P < .001). CONCLUSIONS: The prevalence of bvFTD was higher than expected in this population. To a large extent, different criteria captured different individuals.
