ABSTRACT: Objectives: The aim of this population-based study was to investigate the usefulness of the Geriatric Depression Scale 15-item version (GDS-15) to assess depressive symptoms among very old people with differing levels of cognitive function. Methods: The 834 participants were aged 85 and over. Feasibility of GDS-15 was evaluated as the proportion of people who completed the scale. Concurrent criterion validity was evaluated by calculating correlations between GDS-15 and Philadelphia Geriatric Center Morale Scale (PGCMS). PGCMS measures psychological wellbeing which is closely related with depressive symptoms. Correlations were calculated within groups according to cognitive function assessed with Mini-Mental State Examination (MMSE); 0-4, 5-9, 10-14, 15-19, 20-24, 25-27, and 28-30, using Pearson's two-sided correlation and compared using Fisher r-to-z transformation. Internal consistency of the GDS-15 was evaluated by calculating Cronbach's α in each group. Results: In total, 651 (78%) of the 834 participants completed the GDS-15. For the two MMSE-groups with scores of <10, the proportion who completed GDS-15 were 1% and 42%, respectively, compared to 65-95% in the MMSE-groups with scores of ≥10. Cronbach's α in each MMSE-group ranged from 0.636 (MMSE 28-30) to 0.821 (MMSE 5-9). The level of correlation between GDS-15 and PGCMS did not significantly differ between MMSE-groups with scores of 5-27 compared to the MMSE-group with scores of 28-30. Conclusions: The GDS-15 seems to have an overall usefulness to assess depressive symptoms among very old people with an MMSE score of 10 or more. More studies are needed to strengthen the validity of GDS-15 among older people with MMSE scores of 10-14. For older people with MMSE scores lower than 10, there is a need to develop and validate other measurements.

ABSTRACT: A few studies indicate that self reported physical activity is associated with the risk of fractures in middle-aged and elderly men. We investigated whether objectively measured physical fitness in young adulthood was associated with the risk of low-energy fractures later in life in men. Aerobic capacity and isometric muscle strength were measured in 435445 Swedish men that conscripted for military service from 1969-1978. Incident fractures were searched in national registers. During a median follow-up period of 35 years (range, 11-41 years), 8 030 subjects sustained at least one fracture, increasing the risk of death 1.8 times (95% CI = 1.6-2.0) during follow up. When comparing men in the lowest and highest decile of physical fitness, the risk of a fracture was 1.8 times higher (95% CI = 1.6-2.1) and that of hip fracture was 2.7 times higher (95% CI = 1.6-4.7). The risk of fracture was also 1.4-1.5 times higher when comparing the extreme deciles of muscle strength (p < 0.001 for all). In a subcohort of 1009 twin pairs, up to 22% of the variation in physical fitness and 27-39% of the variation in muscle strength was attributable to environmental factors unique to one twin, e.g. physical activity. In conclusion, low aerobic capacity and muscle strength in young adulthood are associated with an increased risk of low-energy fractures later in life, while a low-energy fracture is associated with an increased risk of death already in middle-aged men. © 2012 American Society for Bone and Mineral Research.

ABSTRACT: Dementia has been associated with an increased risk of fractures. These associations may be explained by an impaired cognitive function, as well as comorbid illness and toxic reaction from drugs. To investigate whether cognitive function in young, healthy individuals already affects the risk of fractures, overall cognitive function scores were calculated from four cognitive tests accomplished during a national conscriptions test in 960,956 men with a mean age of 18 years. Incident fractures were searched in national registers. During a median follow-up of 30 years (range 0 to 41 years), 65,313 men had one fracture and 2589 men had a hip fracture. Compared with men with no fracture, overall cognitive function at baseline was 3.5% lower for men sustaining one fracture and 5.5% lower for men sustaining a hip fracture (p < 0.001 for both). When comparing the lowest and the highest decile, low overall cognitive function scores increased the risk one fracture (hazard ratio [HR] = 1.55, 95% confidence interval [CI] 1.50-1.61) and a hip fracture (HR = 2.12, 95% CI 1.77-2.55), after adjustment for confounders. A higher education (university level versus elementary school) was associated with a decreased risk of a fracture (HR = 0.67, 95% CI 0.65-0.69) and a hip fracture (HR = 0.51, 95% CI 0.45-0.57). The effects of education and cognitive function were reduced when also adjusting for total income and disability pension. In summary, low cognitive function and education in young men were associated with the later risk of especially hip fractures. These associations may partly be mediated by socioeconomic factors. © 2012 American Society for Bone and Mineral Research.

ABSTRACT: There are few studies comparing those who have had and have not had a stroke among those aged 80 years and over, the very old. The aim of this paper was to investigate the prevalence of stroke and the association between stroke and depression in a very old population. This paper is based on cross-sectional data from a population-based study performed between 2005 and 2007. Half of those aged 85 years, all 90-, and 95-year-olds and older in eight urban and rural municipalities in northern Sweden and Finland were invited to participate. A sample of 601 individuals who participated fully in the study was selected. Data were collected through assessments, structured interviews and investigation of medical charts. A specialist in geriatric medicine determined disease status for depression based on medical records and results from the Geriatric Depression Scale (GDS)-15, the Montgomery Åsberg Depression Rating Scale (MADRS) and the Organic Brain Syndrome (OBS) scale, and for stroke based on medical records and reported disease. The prevalence of stroke was 21.5%. The prevalence of depression was 50.4% among those with stroke compared to 34.3% among those without stroke (OR 1.944, p<0.001). In a logistic regression model adjusted for several demographic variables, diseases and functional level, stroke was independently associated with depression (OR 1.644, p=0.038). A large proportion of those with depression, both with and without stroke, were not receiving antidepressant medication. In conclusion, the stroke prevalence was high and stroke showed a strong association with depression among very old people.

ABSTRACT: Physical restraint use is common in institutional care for old people and mainly used to prevent falls, despite the fall-preventive effect of physical restraints being questioned in previous research. The aim of the study was to investigate the use of physical restraints in Sweden in 2000 and 2007.
Data were collected from two comparable census surveys conducted in all institutional care units for old people in 2000 (n = 3,669) and 2007 (n = 2,914). Information on residents' characteristics and physical restraint use was collected using the Multi-Dimensional Dementia Assessment Scale (MDDAS).
In 2000 16.0% (95% confidence interval (CI) 14.8%-17.2%) of the residents were restrained compared to 18.2% (95% CI 16.8%-19.6%) in 2007 (p = 0.017). Adjusting for residents' characteristics showed that residents in 2007 were more likely to be physically restrained, relative to the residents in 2000 (odds ratio (OR) 1.031, 95% CI 1.005-1.058, p = 0.017). In 2007 the residents had been restrained longer, and a higher proportion were restrained for unknown reasons.
Physical restraint use is still common. Moreover, the findings of this study suggest a small increase (OR 1.031) in the prevalence of physical restraint use from 2000 to 2007 adjusted for residents' characteristics.

ABSTRACT: There are many reports of disparities in health and medical care both between women and men and between various age groups. In most cases, men receive better treatment than women and young and middle-aged people are privileged compared with the old and the very old. Cardiovascular morbidity and diabetes mellitus are common, increase with age and are often treated extensively with drugs, many of which are known to have significant adverse effects.
The aim of the study was to analyse gender differences in the pharmacological treatment of cardiovascular disease and diabetes among very old people.
The study took the form of an epidemiological, cross-sectional survey. A structured interview was administered during one or more home visits, and data were further retrieved from medical charts and interviews with relatives, healthcare staff and other carers. Home-dwelling people as well as people living in institutional care in six municipalities in the county of Västerbotten, Sweden, in 2005-7 were included in the study. Half of all people aged 85 years, all of those aged 90 years and all of those aged ≥95 years living in the selected municipalities were selected for inclusion in the study. In total, 467 people were included in the present analysis. The main study outcome measures were medical diagnoses and drug use.
In total, women were prescribed a larger number of drugs than men (mean 7.2 vs 5.4, p < 0.001). Multiple logistic regression models adjusted for age and other background variables as well as relevant medical diagnoses (hypertension, heart failure) showed strong associations between female sex and prescriptions of thiazide diuretics (odds ratio [OR] 4.4; 95% CI 1.8, 10.8; p = 0.001), potassium-sparing diuretics (OR 3.5; 95% CI 1.4, 8.7; p = 0.006) and diuretics as a whole (OR 1.8; 95% CI 1.1, 2.9; p = 0.021). A similar model, adjusted for angina pectoris, showed that female sex was associated with prescription of short-acting nitroglycerin (OR 3.7; 95% CI 1.6, 8.9; p = 0.003). However, more men had been offered coronary artery surgery (p = 0.001). Of the participants diagnosed with diabetes, 55% of the women and 85% of the men used oral antihyperglycaemic drugs (p = 0.020), whereas no gender difference was seen in prescriptions of insulin.
Significant gender disparities in the prescription of several drugs, such as diuretics, nitroglycerin and oral antihyperglycaemic drugs, were observed in this study of very old people. In most cases, women were prescribed more drugs than men. Men more often had undergone coronary artery surgery. These disparities could only in part be explained by differences in diagnoses and symptoms.

ABSTRACT: People with cognitive impairment and dementia have a poor outcome after a hip fracture surgery, about 30-50% of all those who sustain a hip fracture have dementia. Therefore the aim was to investigate whether a multidisciplinary postoperative intervention program could reduce postoperative complications and improve functional recovery among people with dementia.
A randomized controlled trial with subgroup analyses among patients with dementia. Sixty-four patients with femoral neck fracture, aged ≥70 years at Umeå University Hospital, Sweden. The intervention consisted of staff education, individualized care planning and rehabilitation, active prevention, detection and treatment of postoperative complications, especially delirium. The staff worked in teams to apply comprehensive geriatric assessment, management and rehabilitation, including a follow-up at 4 months postoperatively. The control group followed conventional postoperative routines.
There were fewer postoperative complications in the intervention group such as urinary tract infections, p=0.001; nutritional problems, p=0.025; postoperative delirium, p=0.002; falls, p=0.006. At 4 months a larger proportion in the intervention group had regained their previous independent indoor walking ability performance, p=0.005. At 12 months a larger proportion in the intervention group had regained the activities of daily living (ADL) performance level they had before the fracture, p=0.027.
This study demonstrates that patients with dementia who suffer a hip fracture can benefit from multidisciplinary geriatric assessment and rehabilitation and should not be excluded from rehabilitation programs.

ABSTRACT: Behavioral and psychological symptoms, such as verbal or physical aggression, aberrant motor behaviors, psychotic symptoms, anxiety, depressive symptoms and apathy are common among people with dementia. The aim of the present study was to compare the one-week prevalence of behavioral and psychological symptoms and psychotropic drug treatment among people with cognitive impairment living in institutional care, in two large, comparable samples from 2000 and 2007.
A comparison was made between two cross-sectional samples, collected in 2000 and 2007, comprising 4054 participants with cognitive impairment living in geriatric care units in the county of Västerbotten, Sweden. The Multi-Dimensional Dementia Assessment Scale (MDDAS) was used to assess cognitive impairment and behavioral and psychological symptoms. The use of psychotropic drugs was recorded.
Between 2000 and 2007, 15 out of 39 behavioral or psychological symptoms had become less common and no symptoms had become more common, after controlling for demographic changes. Four out of six behaviors within the cluster of aggressive behaviors had declined in prevalence. Patients prescribed anti-dementia drugs increased from 5.1% to 18.0% and antidepressant drug use increased from 43.2% to 49.1%, while anxiolytic, hypnotic, sedative and antipsychotic drug use remained largely unchanged.
The prevalence of many behavioral symptoms had declined from 2000 to 2007, and among these changes, the decline in aggressive behaviors probably has the greatest clinical impact.

ABSTRACT: To evaluate whether age, sex, depression, dementia disorder, nutritional status, or level of functional balance capacity influences the effect of a high-intensity functional weight-bearing exercise program on functional balance.
Preplanned subgroup analyses of a randomized controlled trial.
Nine residential care facilities.
One hundred ninety-one people aged 65 to 100 dependent in activities of daily living and with Mini-Mental State Examination scores of 10 or greater.
A high-intensity functional weight-bearing exercise program or a control activity, each comprising 29 sessions over 3 months.
Functional balance capacity was assessed blindly using the Berg Balance Scale (BBS) at baseline, 3 months, and 6 months. The BBS consists of 14 tasks, common in everyday life, such as standing up from sitting and, while standing, reaching forward or turning 360°. Interactions between allocation to activity group and each subgroup were evaluated according to the intention-to-treat principle.
The subgroup analyses revealed no statistically significant interaction for age, sex, depression, dementia disorder, nutritional status, or level of functional balance capacity at 3 (P=.65, .65, .51, .78, .09, .67, respectively) or 6 (P=.69, .62, .20, .94, .48, .85, respectively) months. In addition, at 3 and 6 months there was no significant interaction for cognitive level (P=.28, .47, respectively) or number of depressive symptoms (P=.85, .49, respectively).
Older age, female sex, depression, mild to moderate dementia syndrome, malnutrition, and severe physical impairment do not seem to have a negative effect on functional balance from a high-intensity functional weight-bearing exercise program. Consequently, people with these characteristics in residential care facilities should not be excluded from offers of rehabilitation including high-intensity exercises.

ABSTRACT: The higher incidence of fractures in women than in men is generally attributed to the lower areal bone mineral density (areal BMD, g/cm(2)) of the former. The purpose of the present study was to investigate both areal BMD and injurious falls as risk factors for fractures. In a first cohort, areal BMD was measured in 5,131 men and women (age range 40-95 years). In a second cohort, consisting of 26,565 men and women (age range 40-69 years), a health survey was conducted including questions about lifestyle and medication. Main outcome measures included validated prospective injurious falls and fractures in both cohorts. The higher areal BMD and femoral neck BMD in men compared to women (P < 0.001) were explained by a higher diameter of the femoral neck. Importantly, the diameter of the femoral neck was not associated with fractures in either sex (hazard ratio [HR] 0.94-1.04, P > 0.05 for all), suggesting that a higher areal BMD and lower incidence of osteoporosis in men do not explain their lower incidence of fractures. In contrast, women were more prone to sustain injurious falls than men in both cohorts investigated (HR for women = 1.61 and 1.84, P < 0.001 for both), resulting in a higher incidence of fractures (HR for women = 2.24 and 2.36, P < 0.001 for both). The number of injurious falls and fractures occurring each month during the study period showed a very strong correlation in both women (r = 0.95, P < 0.00001) and men (r = 0.97, P < 0.00001). In summary, low areal BMD, and thus osteoporosis, may not explain the higher fracture incidence in women than in men. Instead, a higher incidence of injurious falls in women was strongly associated with the higher fracture risk.

ABSTRACT: The aim of the study was to investigate whether urinary tract infection (UTI) in a representative sample of 85-, 90- and ≥95-year-old women is associated with delirium.
In 504 out of 643 women (78.4%) it was possible to evaluate UTI and delirium. Assessments such as the Organic Brain Syndrome (OBS) Scale, the Geriatric Depression Scale-15 (GDS-15) and the Mini-mental State Examination (MMSE) were performed during home visits. Delirium, dementia and depression were diagnosed according to the DSM-IV criteria. A diagnosed, symptomatic UTI with or without ongoing treatment, documented in medical records or detected in association with the assessments, was registered.
Eighty-seven of 504 women (17.2%), were diagnosed as having a UTI with or without ongoing treatment when they were assessed, and almost half of them (44.8%) were diagnosed to be delirious or having had episodes of delirium during the past month. One hundred and thirty-seven of the 504 women (27.2%) were delirious or had had episodes of delirium during the past month and 39 (28.5%) of them were diagnosed to have a UTI. In a multivariate logistic regression model, delirium was significantly associated with Alzheimer's disease (OR = 5.8), multi-infarct dementia (OR = 5.4), depression (OR = 3.1), heart failure (OR = 2.3) and urinary tract infection (OR = 1.9).
A large proportion of very old women with UTI suffered from delirium which might indicate that UTI is a common cause of delirium. There should be more focus on detecting, preventing and treating UTI to avoid unnecessary suffering among old women.

ABSTRACT: it is unknown whether the age-specific prevalence of dementia among the very old changes over time.
this study compares the prevalence of dementia in two population-based cross-sectional samples of very old people in northern Sweden in 2000-02 and in 2005-07. In total, 430 individuals aged 85 and older (mean age 89.5 years, 71.4% women) were evaluated for dementia in the first cross-section and 465 individuals (mean age 90.2 years, 70.9% women) in the second. Trained assessors performed assessments and interviews during home visits and collected information from carers, relatives and medical records. Dementia was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria.
the prevalence of dementia in the total sample was 26.5% in 2000-02 and 37.2% in 2005-07 (P = 0.001). There was also an increase in the prescription of different antihypertensive agents, antilipemic agents and choline esterase inhibitors, and more people had had heart surgery in the later sample.
in this sample of very old people, an increase in the age-specific prevalence of dementia was detected over 5 years. Possible reasons for this may be extended survival among individuals with risk factors for dementia and among individuals with established dementia.

ABSTRACT: This paper is a report of a study exploring possible external and inner sources of the sense of security felt by older people aged 65 and 75. Background. The concept of 'security' has been parsimoniously defined and explored, especially as pertains to older people, and previous research has primarily focused on risks in relation to individuals' declining health and functional ability.
In 2005, population-based cross-sectional surveys were carried out in 15 municipalities in Västerbotten, Sweden and 18 municipalities in Ostrobothnia, Finland. A 15-page questionnaire (84 questions) was distributed, with the final total response rate reaching 68· % (n = 3370): 1825 Swedish-speaking Swedes, 926 Swedish-speaking Finns and 621 Finnish-speaking Finns. The statistical analysis was three-stage, including nominal stepwise regressions.
Older people who indicate that they are 'very secure' are more likely to consider life meaningful and are able to master various life crises. Moreover, they possess confidence in economic institutions and are more likely to feel economically secure. Weak trust in family and friends or neighbours and decreased functional ability seem to indicate a subjective feeling of 'insecurity'.
Caregivers in health care should focus more on supporting older persons' meaningfulness in life and how their feelings of security can be strengthened by trusting relationships and activities. In nursing, there should be more focus on developing knowledge of inner health resources, including positive life orientation and meaningfulness in life.

ABSTRACT: ABSTRACTBackground: Few studies have specifically examined purpose in life among very old people, and we know of none that has used a prospective approach. The aim of this study was to examine changes in purpose in life over five years in very old men and women and to investigate whether depressed mood, malnutrition, inactivity in daily life, or cognitive impairment increased the risk for developing low purpose in life.Methods: The study includes data from 51 participants (42 women and 9 men) living in northern Sweden who completed the Purpose in Life (PIL) Test once at baseline and again five years later.Results: Purpose in life decreased over five years and the decrease was significantly associated with being a woman (p < 0.001) and having depressed mood (p = 0.009) or depression (p = 0.002) at baseline. There were no differences in baseline PIL scores between depressed and not depressed, but those who had depression had significantly decreased PIL scores after five years (p = 0.001).Conclusion: A strong purpose in life does not seem to prevent very old people from developing depression, and being depressed at baseline and living with depression over five years is associated with a loss of purpose in life.

ABSTRACT: ABSTRACTObjectives: The aim of this study was to investigate the prevalence of depression among very old individuals with dementia compared to those without dementia and to examine if there were any differences regarding associated factors between people with or without depression in these conditions.Methods: In a population-based study in Sweden, 363 participants aged 85 years and above, were evaluated for depression and dementia.Results: The prevalence of depression was significantly higher among the people with dementia than without dementia, 43% vs. 24% (p < 0.001). Approximately 2/3 of the depressed in both groups used antidepressants and of those, approximately 50% had responded. Depression in the group without dementia was, among other factors, associated with higher total number of medication, the use of significant more analgesics and benzodiazepines, loneliness, inability of going outside and recent loss of child. The loss of a child was the only factor that was independently associated with depression in those with dementia.Conclusions: The present study confirms that in the very old, depression is more common among people with dementia than without dementia. A large proportion, both with and without dementia, are under-diagnosed and untreated, and in addition many subjects in both groups studied were non-responders to treatment. Many of the factors associated with depression among people without dementia in this study were not associated with depression among those with dementia, thus supporting the theory that the spectrum of associated factors for depression in dementia seems to be different from that for depression in people without dementia.

ABSTRACT: Dementia and depression are common in advanced age, and often co-exist. There are indications of a decreased prevalence of depressive symptoms among old people in recent years, supposedly because of the manifold increase in antidepressant treatment. Whether the prevalence of depressive symptoms has decreased among people in different stages of dementia disorders has not yet been investigated.
A comparison was undertaken of two cross-sectional studies, conducted in 1982 and 2000, comprising 6864 participants living in geriatric care units in the county of Västerbotten, Sweden. Depressive symptoms were measured using the Multi-Dimensional Dementia Assessment Scale (MDDAS), and the cognitive score was measured with Gottfries' cognitive scale. Drug data were obtained from prescription records.
There was a significant decrease in depressive symptom score between 1982 and 2000 in all cognitive function groups except for the group with moderate cognitive impairment. Antidepressant drug use increased in all cognitive function groups.
The prevalence of depressive symptoms decreased between 1982 and 2000, in all levels of cognitive impairment except moderate cognitive impairment. This might possibly be explained by the depressive symptoms having different etiologies in different stages of a dementia disorder, which in turn might not be equally susceptible to antidepressant treatment.

ABSTRACT: To investigate the relationship between purpose in life and depression and, in a five-year follow-up investigate whether purpose in life, adjusted for different background characteristics, can prevent very old men and women from developing depression.
A cross-sectional study included 189 participants (120 women and 69 men) 85-103 years of age living in a county in northern Sweden. Those who had not been diagnosed as depressed at baseline were included in the five-year follow-up study (n = 78). Depression was assessed using the Geriatric Depression Scale-15, the Organic Brain Syndrome scale, the Montgomery-Asberg Depression Rating Scale, and Diagnostic and Statistical Manual of Mental Disorders-IV criteria. Purpose in life was assessed with the Purpose in Life (PIL) scale.
In the cross-sectional study, 40 participants out of 189 (21.2%) were depressed, and those with depression had significantly lower PIL scores (mean score 107 vs. 99, p = 0.014). In the follow-up study, 78 persons were available for the assessment of depression. Of those, 21 (26.9%) were diagnosed as depressed and their mean PIL score at baseline was 106 (SD = 17.4) versus 108 (SD = 16.0, p = 0.750) among those not depressed. Using multivariate logistic regression analysis controlling for possible confounders, we found no association between purpose in life and the risk of developing depression after five years (OR = 1.0, 95% CI 0.97-1.03).
The results show a significant inverse relationship between purpose in life and depression in the cross-sectional study; however, a high PIL score does not seem to serve very old people as a protection against the risk of developing depression.

ABSTRACT: Predisposing factors alone explain only a limited proportion of the variation in fall events, especially in people with dementia. The aim of this study was to identify precipitating factors for falls among people with dementia.
We examined prospective fall registrations over a two-year period on a psychogeriatric hospital ward in the north of Sweden. Circumstances associated with each fall event were analyzed by independent reviewers, possible precipitating factors were documented, evaluated and the most likely precipitating factors were identified. In total, 223 patients with any type of diagnosed dementia were admitted to the ward and 91 fell at least once. Of these, 46 were women and 45 were men (mean age 80.3 years, range 60-94).
A total of 298 falls were registered, 62% of which were sustained by men. The most likely factor or combination of factors could be ascertained in 247 falls (83%). Falls took place at all hours but almost half of the falls (44%) occurred during the nightshift (between 9 pm and 7 am). Acute disease or symptoms of disease and/or acute drug side-effects were, alone or in combination with other factors, judged to precipitate more than three out of four falls.
It is possible to identify many precipitating factors that may contribute to a fall. Falls in people with dementia should be regarded as a symptom of acute disease or as a drug side-effect until proven otherwise. Prompt detection of these relevant factors is, therefore, essential.

ABSTRACT: To evaluate the effects of a high-intensity functional exercise programme on depressive symptoms and psychological well-being among older people dependent in activities of daily living (ADL) and living in residential care facilities.
Cluster-randomized controlled study. Participants were 191 older people, aged 65-100, dependent in ADL and with Mini Mental State Examination scores between 10 and 30. One-hundred (52%) of the participants had a diagnosed dementia disorder. A high-intensity functional weight-bearing exercise programme and a control activity were performed in groups. Sessions were held five times over each two week period for three months, a total of 29 times. The outcome measures, Geriatric Depression Scale (GDS-15) and Philadelphia Geriatric Center Morale Scale (PGCMS) were blindly assessed at baseline, three and six months.
At baseline, mean +/- SD (range) for GDS was 4.4 +/- 3.2 (0-14), and for PGCMS 11.0 +/- 3.5 (2-17). There were no significant differences in GDS or PGCMS between the exercise and the control group at the three and six month follow-ups in the total sample. Among people with dementia, there was a between-group difference at three months in PGCMS scores in favour of the exercise group.
A high-intensity functional exercise programme seems generally not to influence depressive symptoms or psychological well-being among older people dependent in ADL and living in residential care facilities. An individualized and multifactorial intervention may be needed in this group. However, an exercise programme as a single intervention may have a short-term effect on well-being among people with dementia.

ABSTRACT: Hypertension is an established risk factor for dementia. However, the association between blood pressure and cognition in the very old is not fully determined and important to study considering the ageing population and the morbidity associated with cognitive impairment.
This cross-sectional study included 575 individuals aged 85, 90 or 95 years and above and living in northern Sweden or Finland. Participants were interviewed and assessed using a structured protocol. Systolic (SBP) and diastolic blood pressures (DBP) were measured and pulse pressure (PP) calculated. Cognitive function was evaluated using the Mini-Mental State Examination (MMSE). Data were also collected from medical charts and caregivers.
After adjustment for several demographic variables and diagnoses, SBP was significantly associated with MMSE in a nonlinear fashion; both high and low pressures were associated with poorer results. There was also a linear and positive association between PP and MMSE scores, but no association with DBP was found. Participants with dementia had lower blood pressure.
After adjustment for a number of health factors, there was an association between low blood pressure and cognitive impairment. The direction of any causal relationship between blood pressure and cognition remains to be determined.
