- Objective: To study the view of life in dementia. The view of life of an individual is defined as a conception of reality, a central system of values and a basic emotional attitude.Method: Interviews with persons (N = 21) with mild to moderate dementia of the Alzheimer’s type. The interview data were interpreted with a phenomenological hermeneutical method.Results: Despite their cognitive deterioration it was possible to understand the view of life of the participants in the frame of their life story. Their view of life seemed to guide them towards selecting mainly emotionally powerful and value-oriented memories. No exceptional characteristics that could be traced to their dementia disease were found in the participants’ views of life. Conclusions: The view of life of the participants with mild to moderate dementia was vital for their life story and was not erased by dementia.Implications: In order to respect people with dementia as persons, caregivers should strive for gaining some knowledge of their view of life.

- BACKGROUND AND AIMS: There is a great need to evaluate renal function regularly in elderly people. This study aimed at analyzing renal function in stable, community-dwelling elderly people of 75 years and over, to compare measured and predicted glomerular filtration rates (GFR) and to develop an accurate prediction equation for this age group. METHODS: Forty-five ambulatory elderly people in stable health in ordinary living were randomly selected into four age-classes, aged 75-95. Demographic data, personal activities of daily living, continuous drug prescriptions, body composition, blood pressure and blood chemistry were analysed. GFR was measured as Iohexol clearance based on three time-points 3, 4 and 7 hours after Iohexol injection. RESULTS: Mean GFR was well preserved in all four age-classes. The GFR range was 18-83 mL/min and declined with age. The Cockcroft-Gault prediction equation systematically underestimated measured GFR. A new 'GFRA' prediction equation is presented, based on the inverse of serum cystatin C and independent of gender, body surface area, body weight, lean body mass or serum creatinine. The proposed equation underestimated measured GFR with a mean of only 0.1 mL/min, had better precision compared with the Cockcroft-Gault equation, and was evaluated by the method of cross-validation. CONCLUSIONS: GFR exhibits extensive heterogeneity in frail, community-dwelling elderly people. The proposed GFRA was clearly more precise than the Cockcroft-Gault prediction equation in the study group. However, it needs to be validated in a larger population of elderly subjects, including more individuals in stable health with substantially reduced renal function in whom GFR is measured by a reference method with adequate sampling time.

rCBF pathology in Alzheimer's disease is associated with slow processing speed
- 2008

Journal article (peer-reviewed)abstract
- Decreased information processing speed (mental slowing) is a known sequelae of many brain disorders, and can be assessed by continuous naming tasks. Functional imaging studies have shown that pause and articulation times in continuous speech are normally associated with different brain regions, but knowledge about such association in dementia is lacking. We therefore tested the hypothesis that perfusion deficits in Alzheimer's disease (AD) are not only associated with slower processing, but also with these speech measures. Using regional cerebral blood flow (rCBF) measurements during the performance of a continuous colour and form-naming task, we found that naming speed was substantially slower in AD patients than in controls. This slower naming was exclusively determined by an increase in mean pause time, and only to a limited extent by articulation time. The increased pause time was uniquely associated with temporo-parietal rCBF reductions of the patients, while articulation was not. By contrast, the rCBF of healthy elderly control subjects was consistently accompanied by substantially shorter articulation and pause times, although the naming measures were not statistically associated with rCBF. These findings suggest that pause time (in contrast to articulation time) may serve as a sensitive measure in the assessment of information processing speed deficits in dementia, by virtue of its close association with brain pathology.

- Stroke and cognitive impairment are inter-related. The purpose of this study was to show the natural evolution of cognitive performance during the first year after a stroke, and to show which factors that predict cognitive decline. Subjects were patients with a first-ever stroke who were treated in a stroke unit. A total of 160 patients were included. At baseline patients were evaluated with regard to stroke type, stroke severity, pre-stroke dementia and other risk factors. Mini Mental State Examinations (MMSE) were performed after 1 week and after 1 year. Patients had a median increase of 1 point (range -8 to +9) on the MMSE. Thirty-two pre cent of the patients deteriorated, 13% were unchanged, and 55% improved. Lacunar infarction (LI) and left-sided stroke were associated with a failure to exhibit improvement. Patients with LI had an average decline of 1.7 points, whilst patients with other stroke types had an average increase of 1.8 points. Most stroke survivors improve cognitively during the first year after the event. The outcome for LI patients is worse, which suggests that LI may serve as a marker for concomitant processes that cause cognitive decline.

Journal article (peer-reviewed)abstract
- Pain and fatigue are two often overlooked symptoms after stroke. Their prevalence and determinants are not well understood. In this study patients with first-ever stroke (n=377) were examined at baseline and after 1 year. General characteristics of the patients, as well as stroke type, stroke severity and risk factors were registered at baseline. After 1 year survivors (n=253) were examined with respect to residual impairment, disability, cognition and depression. They were asked whether they had experienced pain and/or fatigue which had started after the stroke, and which the patient felt to be stroke related. Twenty-eight patients (11%) had stroke-associated pain and 135 (53%) had stroke-associated fatigue. Pain was associated with depression and different manifestations of stroke severity, especially degree of paresis at baseline. Fatigue was more associated with physical disability. In univariate analysis, fatigue was also associated with sleep disturbances. In conclusion, it is important to be aware of the occurrence of pain and fatigue after stroke, because these symptoms are common, they impair quality of life and they are potentially treatable. Post-stroke depression may coexist with pain and fatigue. The detection of one symptom should lead to consideration of the others. Follow-up and individual assessment of stroke patients is crucial.

- Background/Aims: Clinical short-term trails have shown positive effects of donepezil treatment in patients with Alzheimer's disease. The outcome of continuous long-term treatment in the routine clinical settings remains to be investigated. Methods: The Swedish Alzheimer Treatment Study (SATS) is a descriptive, prospective, longitudinal, multicentre study. Four hundred and thirty-five outpatients with the clinical diagnosis of Alzheimer's disease, received treatment with donepezil. Patients were assessed with Mini-Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog), global rating (CIBIC) and Instrumental Activities of Daily Living (IADL) at baseline and every 6 months for a total period of 3 years. Results: The mean MMSE change from baseline was positive for more than 6 months and in subgroups of patients for 12 months. After 3 years of treatment the mean change from baseline in MMSE-score was 3.8 points (95% CI, 3.0-4.7) and the ADAS-cog rise was 8.2 points (95% CI, 6.4-10.1). This is better than expected in untreated historical cohorts, and better than the ADAS-cog rise calculated by the Stern equation (15.6 points, 95% CI, 14.5-16.6). After 3 years with 38% of the patients remaining, 30% of the them were unchanged or improved in the global assessment. Conclusion: Three-year donepezil treatment showed a positive global and cognitive outcome in the routine clinical setting. Copyright © 2007 S. Karger AG.

Evaluation of dipstick analysis among elderly residents to detect bacteriuria: a cross-sectional study in 32 nursing homes.
- 2009
-
In: BMC geriatrics. - : Springer Science and Business Media LLC. - 1471-2318. ; 9
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Few studies have evaluated dipstick urinalysis for elderly and practically none present confidence intervals. Furthermore, most previous studies combine all bacteria species in a "positive culture". Thus, their evaluation may be inappropriate due to Yule-Simpson's paradox. The aim of this study was to evaluate diagnostic accuracy of dipstick urinalysis for the elderly in nursing homes. METHODS: In this cross-sectional study voided urine specimens were collected from 651 elderly individuals in nursing homes. Dipstick urinalysis for nitrite, leukocyte esterase and urine culture were performed. Sensitivity, specificity, positive and negative predictive values with 95% confidence intervals were calculated. Visual readings were compared to readings with a urine chemistry analyzer. RESULTS: 207/651 (32%) of urine cultures showed growth of a potentially pathogenic bacterium. Combining the two dipsticks improved test characteristics slightly compared to using only one of the dipsticks. When both dipsticks are negative, presence of potentially pathogenic bacteria can be ruled out with a negative predictive value of 88 (84-92)%. Visual and analyzer readings had acceptable agreement. CONCLUSION: When investigating for bacteriuria in elderly people at nursing homes we suggest nitrite and leukocyte esterase dipstick be combined. There are no clinically relevant differences between visual and analyzer dipstick readings. When dipstick urinalysis for nitrite and leukocyte esterase are both negative it is unlikely that the urine culture will show growth of potentially pathogenic bacteria and in a patient with an uncomplicated illness further testing is unnecessary.

-
In: Dementia and Geriatric Cognitive Disorders. - : S. Karger AG. - 1420-8008 .- 1421-9824. ; 21:4, s. 251-259

Journal article (peer-reviewed)abstract
- OBJECTIVES: To investigate whether application of cutoff levels in an episodic memory test (Rey Auditory Verbal Learning Test, RAVLT) is a useful method for identifying patients at high and low risk of cognitive decline and subsequent dementia. METHODS: 224 patients with memory complaints (mean age = 60.7 years, mean MMSE = 28.2) followed-up at a memory clinic over approximately 3 years were assigned retrospectively to one of three memory groups from their baseline results in RAVLT [severe (SIM), moderate (MIM) or no impairment (NIM)]. These groups were investigated regarding cognitive decline. RESULTS: Patients assigned to SIM showed significant cognitive decline and progressed to dementia at a high rate, while a normal performance in RAVLT at baseline (NIM) predicted normal cognition after 3 years. Patients with MIM constituted a heterogeneous group; some patients deteriorated cognitively, while the majority remained stable or improved. CONCLUSIONS: The application of cutoff levels in RAVLT at baseline showed that patients with severely impaired RAVLT performance were at a high risk of cognitive decline and progression to dementia, while patients with normal RAVLT results did not show cognitive decline during 3 years. Furthermore, the initial degree of memory impairment was decisive in the cognitive prognosis 3 years later.

How to identify potential fallers in a stroke unit : validity indexes of 4 test methods
- 2006
-
In: Journal of Rehabilitation Medicine. - : Medical Journals Sweden AB. - 1650-1977 .- 1651-2081. ; 38:3, s. 186-191

Journal article (peer-reviewed)abstract
- OBJECTIVE: The aim of this study was to describe general characteristics of patients with stroke who have a tendency to fall and to determine whether certain test instruments can identify fallers. METHODS: Patients treated in a stroke unit during a 12-month period were included. At inclusion assessments were made with Berg Balance Scale Berg Balance Scale, Stops Walking When Talking, Timed Up & Go (TUG) and diffTUG. At follow-up 6 or 12 months later, patients who had fallen were identified. RESULTS: During the time from discharge to follow-up on 159 patients, 68 patients fell and 91 did not. Fallers fell more often during their initial hospital stay, used sedatives more often and were more visually impaired, compared with non-fallers. The Berg Balance Scale, Stops Walking When Talking and TUG results differed between fallers and non-fallers. The combined results of Berg Balance Scale and Stops Walking When Talking increased the possibility of identifying fallers. CONCLUSION: Berg Balance Scale, Stops Walking When Talking and TUG can be used to evaluate which patients have a tendency to fall in order to carry out preventive measures. Berg Balance Scale can be used in all patients. Stops Walking When Talking can give additional information if the patient is able to walk. TUG is a possible choice, but fewer patients can perform it.
