  • Automated CT-based segmentation and quantification of total intracranial volume
  • 2015
  • Ingår i: European Radiology. - 0938-7994. ; 25:11, s. 3151-3160
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To develop an algorithm to segment and obtain an estimate of total intracranial volume (tICV) from computed tomography (CT) images.MATERIALS AND METHODS: Thirty-six CT examinations from 18 patients were included. Ten patients were examined twice the same day and eight patients twice six months apart (these patients also underwent MRI). The algorithm combines morphological operations, intensity thresholding and mixture modelling. The method was validated against manual delineation and its robustness assessed from repeated imaging examinations. Using automated MRI software, the comparability with MRI was investigated. Volumes were compared based on average relative volume differences and their magnitudes; agreement was shown by a Bland-Altman analysis graph.RESULTS: We observed good agreement between our algorithm and manual delineation of a trained radiologist: the Pearson's correlation coefficient was r = 0.94, tICVml[manual] = 1.05 × tICVml[automated] - 33.78 (R(2) = 0.88). Bland-Altman analysis showed a bias of 31 mL and a standard deviation of 30 mL over a range of 1265 to 1526 mL.CONCLUSIONS: tICV measurements derived from CT using our proposed algorithm have shown to be reliable and consistent compared to manual delineation. However, it appears difficult to directly compare tICV measures between CT and MRI.KEY POINTS: • Automated estimation of tICV is in good agreement with manual tracing. • Consistent tICV estimations from repeated measurements demonstrate the robustness of the algorithm. • Automatically segmented volumes seem less variable than those from manual tracing. • Unbiased and automated tlCV estimation is possible from CT.

  • Secular trends in self reported sexual activity and satisfaction in Swedish 70 year olds: cross sectional survey of four populations, 1971-2001.
  • 2008
  • Ingår i: BMJ (Clinical research ed.). - 1468-5833. ; 337
  • Tidskriftsartikel (refereegranskat)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.

  • A 37-year prospective study of neuroticism and extraversion in women followed from mid-life to late life.
  • 2014
  • Ingår i: Acta psychiatrica Scandinavica. - 1600-0447. ; 129:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Personality traits are presumed to endure over time, but the literature regarding older age is sparse. Furthermore, interpretation may be hampered by the presence of dementia-related personality changes. The aim was to study stability in neuroticism and extraversion in a population sample of women who were followed from mid-life to late life.Method: A population-based sample of women born in 1918, 1922 or 1930 was examined with the Eysenck Personality Inventory (EPI) in 1968-1969. EPI was assessed after 37years in 2005-2006 (n=153). Data from an interim examination after 24years were analysed for the subsample born in 1918 and 1922 (n=75). Women who developed dementia at follow-up examinations were excluded from the analyses.Results: Mean levels of neuroticism and extraversion were stable at both follow-ups. Rank-order and linear correlations between baseline and 37-year follow-up were moderate ranging between 0.49 and 0.69. Individual changes were observed, and only 25% of the variance in personality traits in 2005-2006 could be explained by traits in 1968-1969.Conclusion: Personality is stable at the population level, but there is significant individual variability. These changes could not be attributed to dementia. Research is needed to examine determinants of these changes, as well as their clinical implications.

  • Secular changes in personality: study on 75-year-olds examined in 1976-1977 and 2005-2006.
  • 2013
  • Ingår i: International Journal of Geriatric Psychiatry. - 0885-6230. ; 28:3, s. 298-304
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: In order to study secular changes in personality factors neuroticism and extroversion, representative population samples of non-demented 75-year-olds underwent psychiatric examinations in 1976-1977 (total n?=?223, 138 women, 85 men) and 2005-2006 (total n?=?556, 322 women and 234 men). METHODS: Eysenck Personality Inventory was used at both occasions. Demographic factors (educational level, marital status, having children) were registered. RESULTS: Seventy-five-year-olds examined in 2005-2006 had higher values on extroversion and lower values on the Lie scale compared with those examined in 1976-1977. Neuroticism did not differ between the two birth cohorts. Neuroticism scores were higher in women than in men both in 1976-1977 and 2005-2006, and Lie score was higher in women than in men in 2005-2006. CONCLUSIONS: Our findings suggest that present cohorts of 75-year-olds are more extroverted and less prone to respond in a socially desirable manner than those born three decades earlier. Neuroticism levels remained unchanged, suggesting this trait may be less influenced by environmental factors than the other traits studied.

  • Cerebrospinal Fluid Fatty Acid-Binding Protein 3 is Related to Dementia Development in a Population-Based Sample of Older Adult Women Followed for 8 Years.
  • 2015
  • Ingår i: Journal of Alzheimer's disease : JAD. - 1875-8908. ; Epub ahead of print
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Increased fatty acid-binding protein 3 (FABP-3) levels have been reported in neurodegenerative diseases, including Alzheimer's disease (AD). Cerebrospinal fluid (CSF) FABP-3 has therefore been proposed as a putative marker for dementia. Population-based studies examining whether CSF FABP-3 predicts later development of dementia are lacking. OBJECTIVE: The aim of this study was to examine CSF levels of FABP-3 in relation to later development of dementia in elderly women and in relation to Aβ42, T-tau, P-tau181, and CSF: serum albumin ratio. METHODS: 86 non-demented women aged 70-84 years who participated in the Prospective Population Study of Women in Gothenburg, Sweden took part in a lumbar puncture in 1992-93. CSF-FABP-3, Aβ42, T-tau, P-tau181, and the CSF: serum albumin ratio were measured at baseline. Participants were examined with a neuropsychiatric exam at baseline and at follow-up in 2000. Dementia was diagnosed in accordance with DSM-III-R criteria. RESULTS: Between 1992 and 2000, 8 women developed dementia (4 AD, 3 vascular dementia, 1 mixed vascular dementia and AD). Higher levels of CSF-FABP-3 at baseline were related to development of dementia (OR 1.36 CI [1.05-1.76] p = 0.022) and the subtype AD (OR 1.38 CI [1.06-1.82), p = 0.019) during follow-up. FABP-3 correlated with CSF T-tau (r = 0.88, p <  0.001), P-tau181 (r = 0.619, p <  0.001), and CSF:serum albumin ratio (r = 0.233, p = 0.031), but not with Aβ42 (r = -0.08, p = 0.444)Conclusion: CSF FABP-3 may be an early marker for later development of dementia, probably related to neuronal degeneration, but independent of Aβ metabolism.

  • Tidskriftsartikel (refereegranskat)abstract
    • Department of Primary Health Care, The Sahlgrenska Academy at Göteborg University, Göteborg, Sweden. cecilia.bjorkelund@allmed.gu.se OBJECTIVE: To study the relation between diabetes incidence and sleep problems in a population-based sample of women followed for 32 years. RESEARCH DESIGN AND METHODS: The researchers conducted a prospective population study initiated in 1968-1969, with follow-ups in 1974-1975, 1980-1981, 1992-1993, and 2000-2001 in Gothenburg, Sweden. A total of 1,462 women born in 1908, 1914, 1918, 1922, and 1930, representative of women of the same ages in the general population, initially participated (90% participation rate). Reported sleep duration, sleep problems, and use of sleeping medication were related to incident diabetes from 1968 to 2000. Associations between sleep problems and diabetes were corrected for waist-to-hip ratio (WHR), BMI, subscapular skinfold, fasting blood glucose and serum lipid concentrations, blood pressure, heart rate, smoking, physical activity, education, and socioeconomic status. Additionally, associations between BMI, WHR, and sleep problems were examined. RESULTS: Over 32 years, 126 women (8.7%) developed diabetes. Associations between diabetes and initial sleep problems were tested in a Cox regression analysis, taking into consideration factors associated (P < 0.1) with diabetes. Sleep problems in 1968 did not increase risk of developing diabetes during the following 32 years. Obesity, particularly centralized, was associated with sleep problems. CONCLUSIONS: No association between sleep problems and developing diabetes was seen in this 32-year follow-up of middle-aged women. Obesity, on the other hand, known to cause increased risk of diabetes, was associated with current sleep problems. PMID: 16249549 [PubMed - indexed for MEDLINE]

    • Diabetes mellitus (DM) is associated with an increased risk of mild cognitive impairment, dementia and stroke. The association between DM and dementia appears to be stronger for vascular cognitive impairment than for Alzheimer's disease, suggesting cerebrovascular disease may be an important factor in cognitive impairment in DM. Although the exact mechanisms by which DM affects the brain remain unclear, changes to brain vasculature, disturbances of cerebral insulin signaling, insulin resistance, glucose toxicity, oxidative stress, accumulation of advanced glycation end products, hypoglycemic episodes, and alterations in amyloid metabolism may all be involved. Cognitive impairment and dementia associated with DM may also be mediated via vascular risk factors, in particular brain ischemia, the occurrence of which can have an additive or synergistic effect with concomitant neurodegenerative processes. To date, no drug has been approved for the treatment of vascular dementia and there are no specific pharmacological treatments for preventing or reducing cognitive decline in patients with DM. Most focus has been on tighter management of vascular risk factors, although evidence of reduced cognitive decline through reducing blood pressure, lipid-lowering or tighter glycemic control is inconclusive. Tailored, multimodal therapies may be required to reduce the risk of cognitive dysfunction and decline in patients with DM. The use of pleiotropic drugs with multimodal mechanisms of action (e.g., cerebrolysin, Actovegin) may have a role in the treatment of cognitive dysfunction and their use may warrant further investigation in diabetic populations.

  • Depressive symptoms and risk of stroke: the Rotterdam Study.
  • 2008
  • Ingår i: Journal of neurology, neurosurgery, and psychiatry. - 1468-330X. ; 79:9, s. 997
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Previous studies that have assessed whether the presence of depressive symptoms predisposes to stroke in the general elderly population have been contradictory. Moreover, they did not distinguish between men and women and did not perform psychiatric workups in those with depressive symptoms. This study examines the association between depressive symptoms, depressive disorder and the risk of stroke in the general population. METHODS: This prospective population based cohort study included 4424 participants from the third Rotterdam Study Survey (1997-1999) who, at that time, were > or =61 years of age and free from stroke. Depressive symptoms were assessed using the Centre for Epidemiological Studies Depression Scale (CESD) and considered present if the CESD score was > or =16. Participants with depressive symptoms had a diagnostic interview for depressive disorder. Follow-up was complete until 1 January 2005. Data were analysed using Cox proportional hazards models with adjustment for relevant confounders. RESULTS: Men with depressive symptoms (n = 73) were at increased risk of stroke (adjusted hazard ratio (HR) 2.17; 95% CI 1.11 to 4.23) and ischaemic stroke (adjusted HR 3.21; 95% CI 1.62 to 6.38). These associations were at least partly attributable to men who reported depressive symptoms but who did not fulfil Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV diagnostic criteria for depressive disorder (n = 32): they had a very high risk of stroke (adjusted HR 2.70; 95% CI 1.15 to 6.33) and ischaemic stroke (adjusted HR 4.01; 95% CI 1.68 to 9.57). In women there was no association between presence of depressive symptoms and risk of stroke. CONCLUSIONS: Presence of depressive symptoms is a strong risk factor for stroke in men but not in women.

  • Depression and parkinsonism in older Europeans: results from the EURODEP concerted action.
  • 2010
  • Ingår i: International journal of geriatric psychiatry. - 1099-1166. ; 25:7, s. 679-87

    • OBJECTIVE: The prevalence rate of depression among patients with Parkinson's disease (PD) has been estimated at 25%, although prevalence figures range between 7-76%. Relatively few studies on PD and depression are based on random samples in the general population. Some depressive symptoms can also be understood as symptoms of parkinsonism, and the current study aims to describe which 'overlap' symptoms can be identified in a community sample. METHODS: Data are employed from the EURODEP collaboration. Nine study centres, from eight western European countries, provided data on depression (most GMS-AGECAT), depressive symptoms (EURO-D items and anxiety), parkinsonism (self-report of PD or clinical signs of PD), functional disability and dementia diagnosis. RESULTS: Data were complete for 16 313 respondents, aged 65 and older; 306 (1.9%) reported or had signs of parkinsonism. The rate of depression was about twice as high among respondents with parkinsonism (unadjusted Odds Ratio 2.44, 95% Confidence Interval 1.88-3.17), also among those without functional disability. 'Overlap' symptoms between parkinsonism and depression, were represented by motivation and concentration problems, appetite problems and especially the symptom of fatigue (energy loss). However, principal component analysis showed that these 'overlap' symptoms loaded on different factors of the EURO-D scale. CONCLUSIONS: As among clinical patients with PD, depression is highly common in community dwelling older people with parkinsonism, even among those without functional disability. Although fatigue did not strongly relate to motivational symptoms, both types of 'overlap' symptoms possibly trigger a final common pathway towards a full depressive syndrome.
