Tidskriftsartikel (refereegranskat)abstract
- The aims are to study personality characteristics of patients with memory complaints and to assess the presence of objective (OMI) versus subjective (SMI) memory impairment, the affective status, as well as potential gender differences. The patients were assessed by means of a neuropsychiatric examination and a neuropsychological test-battery. The Swedish version of the revised NEO Personality Inventory (NEO PI-R) and the Hospital Anxiety and Depression Scale (HADS) were used. The 57 patients (38 women, 19 men, mean age 56.9) differed from the Swedish normative group in three of the five personality factors: neuroticism, extraversion and agreeableness. This was mainly because of the scores of the female patients. Approximately half of the patients had OMI. No differences regarding personality factors or affective status were found between OMI and SMI patients. The female patients scored significantly higher than the male patients on symptoms of anxiety and depression. Neuroticism and symptoms of depression interacted with memory performance and gender. Our findings demonstrate the importance of applying an objective assessment of memory functions and a gender perspective when studying patients with memory complaints.

Genetic Studies of Alzheimer's Disease
- 2008

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Patients with Alzheimer's disease (AD) often have a family history of the disease, implicating genetics as a major risk factor. Three genes are currently known to cause familial early-onset AD (<65 years): the amyloid precursor protein (APP) and the presenilins (PSEN1 and PSEN2). For the much more common late-onset disease (>65 years), only the APOE gene has repeatedly been associated to AD, where the ε4 allele increases disease risk and decreases age at onset. As APOE ε4 only explains part of the total estimated disease risk, more genes are expected to contribute to AD.This thesis has focused on the study of genetic risk factors involved in AD. In the first study, we conducted a linkage analysis of six chromosomes previously implicated in AD in a collection of affected relative pairs from Sweden, the UK and the USA. An earlier described linkage peak on chromosome 10q21 could not be replicated in the current sample, while significant linkage was demonstrated to chromosome 19q13 where the APOE gene is located. The linkage to 19q13 was further analyzed in the second study, demonstrating no significant evidence of genes other than APOE contributing to this peak. In the third study, the prevalence of APP duplications, a recently reported cause of early-onset AD, was investigated. No APP duplications were identified in 141 Swedish and Finnish early-onset AD patients, implying that this is not a common disease mechanism in the Scandinavian population. In the fourth study, genes with altered mRNA levels in the brain of a transgenic AD mouse model (tgAPP-ArcSwe) were identified using microarray analysis. Differentially expressed genes were further analyzed in AD brain. Two genes from the Wnt signaling pathway, TCF7L2 and MYC, had significantly increased mRNA levels in both transgenic mice and in AD brains, implicating cell differentiation and possibly neurogenesis in AD.

Falls in people with dementia
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Falls and concomitant injuries are common problems among large groups of the elderly population, leading to immobility and mortality. These problems are even more pronounced among people suffering from dementia. This thesis targets fall risk factors for people with dementia in institutions. The overall aim of this thesis was to investigate risk factors for falls, predisposing as well as related to circumstances surrounding falls, and to do this as efficiently as possible. In a prospective cohort study including residents of residential care facilities with and without dementia, the fall rate was higher for those with dementia, the crude incidence rate ratio (IRR) was 2.55 (95% CI 1.60–4.08) and the adjusted IRR was 3.79 (95% CI 1.95–7.36). In the group of people suffering from dementia, including 103 residents, a total of 197 falls resulted in 11 fractures during the 6-months follow-up period. From the same baseline measurements 26% and 55%, respectively, of the variation in falls could be explained in the group of residents with and without dementia. Fall predictors significantly and independently associated with an increased risk of falls in the group of people suffering from dementia were the category “man walking with an aid” and the use of more than four drugs. In a prospective cohort study, including 204 patients in a psychogeriatric ward, a total of 244 falls resulted in 14 fractures. Fall predictors significantly and independently associated with an increased risk of falls were male sex, failure to copy a design, use of clomethiazole, and walking difficulties. Treatment with statins was associated with a reduced risk of falls. With these fall predictors in the negative binomial regression (Nbreg) model, 48% of the variation in falls was explained. The data from the psychogeriatric ward were also analysed with the use of partial least squares regression (PLS) and regression tree to be compared with the results of the Nbreg analysis. PLS and regression tree are techniques based on combinations of variables. They both showed similar patterns, that a combination of a more severe level of dementia, behavioral complications and medication related to these complications is associated with an increased fall rate. Thirty-two percent and 38%, respectively, of the variation in fall rate were explained in the PLS and regression tree analysis. The circumstances surrounding the falls in the psychogeriatric ward were analysed. It was found that the fall rate was equally high during the night and the day. A large proportion of the falls was sustained in the patients’ own room and a small proportion of the falls was witnessed by the staff. This pattern was even more pronounced during the night. The proportion of diurnal rhythm disturbances and activity disturbances was higher for falls at night than for falls during the day. Circumstances associated with an increased risk of falls, as shown by a short time to first fall, were anxiety, darkness, not wearing any shoes and, for women, urinary tract infection. The proportion of urinary tract infection was also higher in connection to falls sustained by women than to falls sustained by men. This thesis confirms that people suffering from dementia are prone to fall. Walking difficulties, male sex and impaired visual perception are factors that should be considered in the work of reducing falls among people suffering from dementia. Furthermore, falls at night, behavioral complications and medication related to these complications should also be considered in this work, especially as the dementia disease progresses. A larger portion of the variation of the outcome variable was explained by the Nbreg model than the regression tree and PLS. However, these statistical methods, based on combinations of variables, gave a complementary perspective on how the fall predictors were related to falls.

Culturally congruent care for older people: Finnish care in Sweden
- 2007
-
Ingår i: Scandinavian Journal of Caring Science. ; 21, s. 354-361
-
Tidskriftsartikel (refereegranskat)abstract
- An increasing number of older people belong to minority and immigrant groups. This calls for new models on the subject of how to provide culturally adjusted care for these populations. The aim of this study is to describe how culturally congruency is used in care for older Finnish immigrants in order to promote their well-being. The study was conducted with an ethnographic design, based on participant observations and interviews among residents, staff and visitors in the Finnish Home in Sweden. In the core of the cultural congruency is the use of the Finnish language, and the fact that both residents and staff have Finnish backgrounds. In addition to this, Finnish customs and celebrations, popular culture and topics of discussion, are actively used in order to create a common ground for communication and shared understanding of the individual person. Cultural congruency, based on the residents' mother language, shared athnic background with staff, and shared customs creates a common ground for communication and an understanding. This enables caring relationships, which, in turn, increases the residents' well-being.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: The authors studied factors associated with falls among cognitively impaired older people in geriatric care settings.Method: This was a study using all geriatric care settings in a county in northern Sweden. Residents were assessed by means of the Multi-Dimensional Dementia Assessment Scale, supplemented with questions concerning the use of physical restraints, pain, previous falls during the stay, and falls and injuries during the preceding week. Data about both falls and cognition were collected in 3,323 residents age 65 and older. Of these residents 2,008 (60.4%) were cognitively impaired, and they became the study population. Of the participants, 69% were women; mean age: 83.5 years.RESULTS: Of 2,008 cognitively impaired residents, 189 (9.4%) had fallen at least once during the preceding week. Being able to get up from a chair, previous falls, needing a helper when walking, and hyperactive symptoms were the factors most strongly associated with falls.CONCLUSION: Preventing falls in cognitively impaired older people is particularly difficult. An intervention strategy would probably have to include treatment of psychiatric and behavioral symptoms, improvement of gait and balance, and adjustment of drug treatment, as well as careful staff supervision.
