Mediation of perceived stress and cortisol in the association between neuroticism and global cognition in older adults: A longitudinal study.
2021
Neuroticism has been associated with a greater dementia risk, but its association with cognitive decline in healthy older adults remains unclear. Stress has been proposed as one of the mechanisms that could explain this relationship. Our aim was to analyse, in healthy older people, the mediating role of perceived stress and the Hypothalamic–Pituitary–Adrenal (HPA) axis in the association between neuroticism and global cognition. At Waves 1 and 2 (4-year follow-up), 87 older people (49.4% women; M age = 65.08, SD = 4.54 at Wave 1) completed a neuropsychological battery and the Perceived Stress Scale (PSS), and provided saliva samples on two (Wave 1) and three (Wave 2) consecutive days to mea…
Effects of Multidomain Risk Accumulation on Cognitive, Academic, and Behavioural Outcomes
2009
This longitudinal study examined the predictive associations between cumulative multidomain risk factors and cognitive (IQ), academic (reading fluency), and social adaptive outcomes at 8 to 9 years among 190 children with or without familial risk for dyslexia. Other risk factors included parental and neurocognitive risks assessed when the children were 1 to 6 years of age. Risks accumulated more among children with familial risk for dyslexia than among children without familial risk. A higher number of risks was associated with poorer performance in all outcome measures as postulated by the cumulative risk model. However, when the effects of individual risk variables were controlled for at …
Trajectories of mobility limitations over 24 years and their characterization by shift work and leisure-time physical activity in midlife.
2019
Abstract Background We aimed to investigate trajectories of mobility limitations (MLs) over a period of 24 years. In addition, we aimed to study how shift work and leisure-time physical activity (LTPA) in midlife predict assignment to MLs trajectories separately for those retired on statutory pensions (SPs) and on disability pensions (DPs). Methods Subjects who responded MLs questionnaires (1985–2009, N = 3048) in Finnish Longitudinal Study on Aging Municipal Employees were included in this prospective cohort study. LTPA and shift work were measured during baseline. International Classification of Functioning was used to code MLs. Growth mixture modeling was used to identify the trajectorie…
Well-Being Among Older Gay and Bisexual Men and Women in England: A Cross-sectional Population Study
2019
Objectives: Lesbian, gay, and bisexual (LGB) older people present an under-represented population in research, with limited research citing higher prevelance of depression, loneliness, rejection, and overall poorer health and well-being outcomes. Our study compares well-being, defined as quality of life, life satisfaction, sexual satisfaction, and depression, among LGB people with their heterosexual peers'. Design: Cross-sectional population study using data from the English Longitudinal Study of Aging (ELSA), a representative panel study of older adults aged 50 and older. Setting and Participants: Data were from ELSA wave 6, collected 2012-2013. A total of 5691 participants were included i…
Comprehension of metaphors and idioms in patients with Alzheimer's disease - A longitudinal study
2001
Language in patients with Alzheimer's disease has been extensively studied, with the exception of non-literal language comprehension. However, in our speech, we often make use of expressions, which are not necessarily interpreted on a literal ground. Comprehension of metaphors and idioms was examined in 39 patients with probable early Alzheimer's disease. The results showed that the decline of figurative language is not an early symptom of dementia and can occur independently from the impairment of propositional language. It was also found that metaphors and idioms differ as far as the predominant kind of error is concerned.
Heterogeneity in Risk Factors for Cognitive Impairment, No Dementia: Population-Based Longitudinal Study From the Kungsholmen Project
2006
OBJECTIVES: The objectives of this study were to investigate the relation of vascular, neuropsychiatric, social, and frailty-related factors with "Cognitive impairment, no dementia" (CIND) and to verify their effect independently of future progression to Alzheimer disease (AD). METHODS: Seven hundred eighteen subjects aged 75+ years who attended baseline, 3- and 6-year follow-up examinations of the Kungsholmen Project, a Swedish prospective cohort study, were studied. CIND was defined according to the performance on the Mini-Mental State Examination. Potential risk factors were collected at baseline and clustered according to four research hypotheses (frailty, vascular, neuropsychiatric, an…
Understanding developmental language disorder-The Helsinki longitudinal SLI study (HelSLI): A study protocol
2018
Background Developmental language disorder (DLD, also called specific language impairment, SLI) is a common developmental disorder comprising the largest disability group in pre-school-aged children. Approximately 7% of the population is expected to have developmental language difficulties. However, the specific etiological factors leading to DLD are not yet known and even the typical linguistic features appear to vary by language. We present here a project that investigates DLD at multiple levels of analysis and aims to make the reliable prediction and early identification of the difficulties possible. Following the multiple deficit model of developmental disorders, we investigate the DLD …

The role of educational track in adolescents' school burnout: a longitudinal study.
2008
Background Transition from comprehensive school to later educational tracks is challenging for many adolescents. The present three-wave longitudinal study conducted in Finland considers this issue from the perspective of school burnout. Aims The study investigated the extent to which school-related burnout (exhaustion, cynicism, and feelings of inadequacy) changes during the transition from comprehensive school to an academic or vocational track. Sample The participants of the present study were 658 ninth graders, who filled in questionnaires twice during their final term of comprehensive school and once after the transition to post-comprehensive schooling. Methods The participants filled i…
Early Cognitive Precursors of Children's Mathematics Learning Disability and Persistent Low Achievement: A 5-Year Longitudinal Study.
2018
Mathematical difficulties have been distinguished as mathematics learning disability (MLD) and persistent low achievement (LA). Based on 1,880 Finnish children who were followed from kindergarten (age 6) to fourth grade, this study examined the early risk factors for MLD and LA. Distinct groups of MLD (6.0% of the sample) and LA (25.7%) children were identified on the basis of their mathematics performance between first and fourth grades with latent class growth modeling. Impairment in the same set of cognitive skills, including language, spatial, and counting skills, was found to underlie MLD and LA. The finding highlights the importance of monitoring mathematical development across the ea…
