- Aggregation of amyloid-beta is one of the major characteristics in brains of patients with Alzheimer's disease (AD). Although several mechanisms behind the formation of such aggregates have been suggested the regulatory factors are still unknown. The present study aimed at investigating the association of lysyl oxidase-like 1 (LOXL1) polymorphisms with AD diagnosis and cerebrospinal fluid biomarkers (CSF) for the disease. Proteins of the lysyl oxidase (LOX) family are involved in cross-linking extracellular matrix proteins to insoluble fibers and have been associated with neurodegenerative diseases including AD. Genetic polymorphisms in LOXL1 (rs1048661, rs3825942, and rs2165241) have been linked to exfoliation syndrome and exfoliation glaucoma, conditions that have shown association with AD. The polymorphisms were genotyped by Taqman allelic discrimination in a study sample including AD patients (n = 318) and controls (n = 575). In a subgroup of the population, the polymorphisms were analyzed in relation to APOE epsilon 4 genotype and to CSF (T-tau, P-tau, and A beta(1-42)). No evidence for associations of these polymorphisms with risk for AD or any of the studied CSF biomarkers measured was found. These results do not support LOXL1 as being a major risk gene for AD.

A 10-Year Follow-Up of Adiposity and Dementia in Swedish Adults Aged 70 Years and Older
- 2018
-
In: Journal of Alzheimers Disease. - : IOS Press. - 1387-2877 .- 1875-8908. ; 63:4, s. 1325-1335
-
Journal article (peer-reviewed)abstract
- Background: Adiposity measured in mid-or late-life and estimated using anthropometric measures such as body mass index (BMI) and waist-to-hip ratio (WHR), or metabolic markers such as blood leptin and adiponectin levels, is associated with late-onset dementia risk. However, during later life, this association may reverse and aging- and dementia-related processes may differentially affect adiposity measures. Objective: We explored associations of concurrent BMI, WHR, and blood leptin and high molecular weight adiponectin levels with dementia occurrence. Methods: 924 Swedish community-dwelling elderly without dementia, aged 70 years and older, systematically-sampled by birth day and birth year population-based in the Gothenburg city region of Sweden. The Gothenburg Birth Cohort Studies are designed for evaluating risk and protective factors for dementia. All dementias diagnosed after age 70 for 10 years were identified. Multivariable logistic regression models were used to predict dementia occurrence between 2000-2005, 2005-2010, and 2000-2010 after excluding prevalent baseline (year 2000) dementias. Baseline levels of BMI, WHR, leptin, and adiponectin were used. Results: Within 5 years of baseline, low BMI (<20 kg/m(2)) was associated with higher odds of dementia compared to those in the healthy BMI category (>= 20-24.9 kg/m(2)). Compared to the lowest quartile, leptin levels in the second quartile were associated with lower odds of dementia in women (p < 0.05). Conclusion: In late-life, anthropometric and metabolic adiposity measures appear to be differentially associated with dementia risk. While BMI and leptin levels are highly positively correlated, our results show that their association with dementia at age >= 70 years, is asynchronous. These data suggest that with aging, the complexity of the adiposity exposure may increase and suggests metabolic dysregulation. Additional studies are needed to better understand this complexity.

Journal article (peer-reviewed)abstract
- OBJECTIVE: To study secular trends in self reported sexual behaviour among 70 year olds. DESIGN: Cross sectional survey. Settings Four samples representative of the general population in Gothenburg, Sweden. PARTICIPANTS: 1506 adults (946 women, 560 men) examined in 1971-2, 1976-7, 1992-3, and 2000-1. MAIN OUTCOME MEASURES: Sexual intercourse, attitudes to sexuality in later life, sexual dysfunctions, and marital satisfaction. RESULTS: From 1971 to 2000 the proportion of 70 year olds reporting sexual intercourse increased among all groups: married men from 52% to 68% (P=0.002), married women from 38% to 56% (P=0.001), unmarried men from 30% to 54% (P=0.016), and unmarried women from 0.8% to 12% (P<0.001). Men and women from later birth cohorts reported higher satisfaction with sexuality, fewer sexual dysfunctions, and more positive attitudes to sexuality in later life than those from earlier birth cohorts. A larger proportion of men (57% v 40%, P<0.001) and women (52% v 35%, P<0.001) reported very happy relationships in 2000-1 compared with those in 1971-2. Sexual debut before age 20 increased in both sexes: in men from 52% to 77% (P<0.001) and in women from 19% to 64% (P<0.001). CONCLUSION: Self reported quantity and quality of sexual experiences among Swedish 70 year olds has improved over a 30 year period.

37 years of body mass index and dementia: observations from the prospective population study of women in Gothenburg, Sweden.
- 2012

In: Journal of Alzheimer's disease : JAD. - 1875-8908. ; 28:1, s. 163-71

Journal article (peer-reviewed)abstract
- Level of adiposity is linked to dementia in epidemiological studies. Overweight and obesity in mid- and late-life may increase risk for dementia, whereas decline in body weight or body mass index (BMI) and underweight in years preceding and at the time of a dementia diagnosis may also relate to dementia. Longitudinal studies with sufficient follow-up are necessary to estimate trajectories that allow better understanding of the relationship between adiposity indices and dementia over the life course. We evaluated the natural history of BMI in relationship to clinical dementia over 37 years in the Prospective Population Study of Women (PPSW) in Sweden. PPSW is a systematic sample of 1462 women born 1908, 1914, 1918, 1922, and 1930 and aged 38-60 years at baseline. Examinations occurred in 1968, 1974, 1980, 1992, 2000, and 2005. Statistical analyses were conducted using mixed effects regression models. Trajectories of BMI over 37 years as a function of age differed between women who did versus did not develop dementia. Women developing dementia evidenced a lesser increase in BMI from age 38 to 70 years. After age 70, the BMI slope decreased similarly (no "accelerated decline") irrespective of dementia status. A lower BMI before and during dementia onset was observed. Women with similar BMI at mid-life exhibited a different pattern of BMI change as they approached late-life that was related to dementia onset. BMI may be a potential marker of dementia-related neuropathologies in the brain. Dementia is related to a common risk factor, BMI, from mid-to late-life.

Five-year mortality in relation to dementia and cognitive function in 95-year-olds.
- 2007
-
In: Neurology. - : Ovid Technologies (Wolters Kluwer Health). - 0028-3878 .- 1526-632X. ; 69:22, s. 2069-75

Journal article (peer-reviewed)abstract
- BACKGROUND: Dementia is a known predictor of mortality, but most studies include small numbers of participants above age 90. The influence of dementia or cognition on mortality in this age group is therefore uncertain. OBJECTIVE: To examine 5-year mortality in relation to dementia and cognitive performance at age 95. METHODS: A population sample of 338 individuals examined at age 95 was followed to age 100. Dementia was diagnosed according to DSM-III-R criteria. Cognitive function was measured using the Mini-Mental State Examination (MMSE). Information on severe physical disorders was obtained from the Swedish Hospital Discharge Register, and date of death from the Swedish Population Register. RESULTS: Five-year mortality was higher in 95-year-olds with dementia than in 95-year-olds without dementia (96% vs 73%; p < 0.0001), even when adjusting for severe physical disorders. A Cox regression analysis with calculation of population attributable risk (PAR), calculated from adjusted relative risks, showed that mortality was predicted by dementia (PAR 42%), cardiac disease (PAR 17%), cancer (PAR 6%), and male sex (PAR 7%), but not by stroke. Among the subjects without dementia, cognitive performance measured using the MMSE (n = 133 with complete tests; 81% of the subjects without dementia) predicted mortality. For each point increase in the MMSE, mortality decreased by 13%. CONCLUSIONS: In 95-year-olds, dementia, as well as cognitive performance in the subjects without dementia, influences mortality. When controlling for other severe medical conditions we found dementia to be the leading cause of deaths among the oldest old. The reason why dementia and cognitive function predict life expectancy requires further elucidation.

Journal article (peer-reviewed)abstract
- OBJECTIVE:: To determine the 1-month prevalence of mental disorders among 95-year olds. DESIGN:: Cross-sectional population sample of 95-year olds. SETTING:: All 95-year olds born in the period 1901-1903 living in Gothenburg, Sweden, were invited. Elderly living in both community settings and nursing homes were included. PARTICIPANTS:: In total, 338 95-year olds (response rate: 65%) were examined (263 women, 75 men). MEASUREMENTS:: All participants were examined by psychiatrists using the Comprehensive Psychopathological Rating Scale and cognitive tests. Mental disorders were classified according to Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised criteria. RESULTS:: Two-third of all 95-year olds had a mental disorder. In the total sample of 95-year olds, the 1-month prevalence was 52% for dementia, 8% for depression, 4% for anxiety, and 3% for psychotic disorders. Almost one-third (29%) of the nondemented 95-year olds fulfilled criteria for a psychiatric disorder: 17% had depression, 9% anxiety, and 7% psychotic disorder. CONCLUSIONS:: The combined prevalence of mental disorders was high among 95-year olds, even after excluding dementia. These findings emphasize the importance of research, care, and detection of psychiatric problems in this age group.

Journal article (peer-reviewed)abstract
- The receptor for advanced glycation end-products (RAGE) has been implicated in several pathophysiological processes relevant to Alzheimer's disease (AD), including transport and synaptotoxicity of AD-associated amyloid beta (A beta) peptides. A recent Chinese study (Li et al. in J Neural Transm 117:97-104, 2010) suggested an association between the 82S allele of the functional single nucleotide polymorphism (SNP) G82S (rs2070600) in the RAGE-encoding gene AGER and risk of AD. The present study aimed to investigate associations between AGER, AD diagnosis, cognitive scores and cerebrospinal fluid AD biomarkers in a European cohort of 316 neurochemically verified AD cases and 579 controls. Aside from G82S, three additional tag SNPs were analyzed to cover the common genetic variation in AGER. The 82S allele was associated with increased risk of AD (P (c) = 0.04, OR = 2.0, 95% CI 1.2-3.4). There was no genetic interaction between AGER 82S and APOE epsilon 4 in producing increased risk of AD (P = 0.4), and none of the AGER SNPs showed association with A beta(42), T-tau, P-tau(181) or mini-mental state examination scores. The data speak for a weak, but significant effect of AGER on risk of AD.

Journal article (peer-reviewed)abstract
- 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.

Journal article (peer-reviewed)abstract
- Depression is a common and serious disorder that may have developmental origins. Birth-related factors have been related to childhood and adult occurrence of somatic as well as psychiatric disorders, but studies on the relationship between birth-related factors and depression are few and show mixed results. In addition, varying methods have been used to assess depression. Standardized clinical criteria to diagnose depression, combined with birth data collected from midwife records have not been used in most studies. Participants in the Prospective Population Study of Women in Sweden (803 women), born 1914, 1918, 1922 and 1930, provide information on birth factors and depression. Women participated from 1968 at mid-life ages of 38-60 years, to 2000, when they were age 78-92 years. Original birth records containing birth weight, length, head circumference, and gestational time, as well as social factors were obtained. Lifetime depression was diagnosed via multiple information sources. Symptoms were assessed using the Comprehensive Psychopathological Rating Scale and diagnoses were based on DSM-III-R criteria. Over their lifetime, 44.6% of women in this sample experienced depression. Birth weights ≤ 3500 g [odds ratio (OR), age-adjusted = 1.72; 95% CI 1.29-2.28, P < 0.001] and shorter gestational time (OR, age-adjusted = 1.13; 95% CI 1.04-1.24, P = 0.005) were independently associated with a higher odds of lifetime depression in a logistic regression model adjusted for age. Lower than median birth weights and shorter gestational time were related to lifetime depression in women. Both neurodevelopmental and environmental contributions to lifetime depression may be considered.
