- Previous studies have failed to reach consensus on insulin levels in cerebrospinal fluid of Alzheimer's disease (AD) patients and on its relation to pathological features. We performed a new analysis in patients at different stages of AD, and investigated the relationship of insulin levels with biochemical disease markers and with cognitive score. We included 99 patients from our Memory Clinic (Karolinska University Hospital, Sweden), including: 27 patients with mild AD, 13 that progressed from mild cognitive impairment (MCI) to AD in two years time, 26 with MCI stable after two years, and 33 with subjective cognitive impairment. Insulin was significantly decreased in the cerebrospinal fluid of both women and men with mild AD. Insulin deficits were seen in women belonging to both MCI groups, suggesting that this occurs earlier than in men. Insulin was positively associated with amyloid-β 1-42 (Aβ1-42) levels and cognitive score. Furthermore, total-tau/(Aβ1-42*insulin) ratio showed strikingly better sensitivity and specificity than the total-tau/Aβ1-42 ratio for early AD diagnosis in women.

- Objective: To determine the extent and rate of drug use and to evaluate the patterns of drug use over time in a very elderly population, we analysed drug use data from phases I (1987-1989) and IV (1994-1996) of the Kungsholmen project, an ongoing longitudinal study on aging in Stockholm, Sweden.Study Participants: Complete drug information was obtained from 1001 subjects in the 1987-1989 study period, and 681 subjects in 1994-1996. The participants were predominantly women and the average age was 85.8 years in 1987-1989 and 86.9 years in 1994-1996.Results: The proportion of users increased from 87.6 to 94.1% and the overall average number of drugs used per subject increased significantly (p < 0.001) from 3.4 to 4.6. Significant differences (p < 0.05) were noted in all age groups and in all types of housing. The frequency of use increased for all classes of drugs. The most frequently used in both study periods were drugs for the nervous system, cardiovascular system, and alimentary tract and metabolism. With regard to therapeutic categories of drugs, the use of vitamins, antithrombotic agents, antianaemic preparations, ACE inhibitors, antibacterials, analgesics, psychoanaleptics, and antiglaucoma preparations increased significantly (p < 0.05). The increased use of these drugs indicated heightened awareness of the most common and preventable medical conditions affecting the elderly and the use of newer classes of drugs. This also study confirmed a high prevalence of drug use and polypharmacy even in the very elderly, and the importance of evaluating the effects and appropriateness of drug use in this population.

- ObjectiveTo determine the prevalence of psychotropic drug use in very old persons with and without dementia in two time periods, and describe the patterns of psychotropic drug use between institutions and non-institutions.MethodsDescriptive analysis on a sample of subjects aged 81+ from a population-based study in Stockholm, Sweden. Psychotropic drug use data were collected from the 1987-1989 and 1994-1996 periods of the study. The diagnosis of dementia was based on the DSM III-R.ResultsAbout 41% of the subjects used at least one psychotropic drug in both periods. Women and subjects in institutions more commonly used psychotropic drugs. The most commonly reported were, in rank order, hypnotics-sedatives, anxiolytics, antipsychotics and antidepressants. Hypnotics-sedatives and anxiolytics were the most commonly used in both institutions and non-institutions. More persons with dementia used psychotropic drugs in both periods. The use of newer drugs, for example, SSRI, was evident. Multivariate analyses showed increased risk for psychotropic drug use among subjects in institutions.ConclusionsThis study confirms the high rate of psychotropic drug use in the very old, particularly in persons with dementia. Psychotropic drug use was high among subjects living in institutions.

- Background. Complaints of disturbed or dissatisfied sleep are common among older people. This study aimed to evaluate the prevalence of sleep problems in very old persons and its relation to physical and mental health and drug use. Methods. This is a cross-sectional analysis of sleep problems in a population of old persons living in Stockholm, Sweden. There were 641 subjects aged 81+ years; 77.8% were women, 91.4% were noninstitutionalized, and 68.6% lived alone. All persons underwent a comprehensive medical and psychiatric interview and examination. Sleep problems were assessed using the Clinical Psychopathological Rating Scale (CPRS). Covariates included chronic medical conditions, depression, dementia, pain, self-rated health, activities of daily living, use of hypnotics-sedatives, use of other psychotropic drugs, and use of nonpsychotropic drugs. Results. More than one third of subjects were identified with sleep problems. They were more common among women and persons using a higher number of drugs. Poor self-rated health, depression, and pain were related to the presence of sleep problems. Among persons with sleep problems and depression, only 19.2% used antidepressants, and 46.2% used hypnotics-sedatives. Among persons with sleep problems and pain, 63.2% used analgesics, and 47.0% used hypnotics-sedatives. One or more chronic diseases, use of hypnotics-sedatives, use of other psychotropic drugs, and use of nonpsychotropic drugs were also related to sleep problems. After multivariate analysis, factors significantly related to sleep problems were female gender, depression, pain, and hypnotic-sedative use. Conclusions. Sleep problems were common in this very old population. These results suggest the importance of carefully assessing an older person's complaints to accurately diagnose and effectively treat sleep problems.

- OBJECTIVE: To assess the extent of inappropriateness of drug use in an older nondemented and demented population. DESIGN: Descriptive analysis based on data from a sample of older subjects age 81 years and older. Data were collected from the second follow-up conducted in 1994–1996. SETTING: A population-based study of the Kungsholmen project in Stockholm, Sweden. PARTICIPANTS: Drug information was obtained from 681 subjects with a mean age of 86.9 years. The subjects were predominantly women (78%). Thirteen percent resided in institutions and 27.6% were diagnosed with dementia. MEASUREMENTS: Dementia diagnosis based on DSM III-R. Criteria for inappropriateness of drug use: use of drugs with potent anticholinergic properties, drug duplication, potential drug-drug and drug-disease interactions, and inappropriate drug dosage. RESULTS: The mean number of drugs used was 4.6: 4.5 drugs for nondemented and 4.8 for demented subjects. Nondemented subjects more commonly used cardiovascular-system drugs and demented subjects used nervous-system drugs. Demented subjects were more commonly exposed to drug duplication and to drugs with potent anticholinergic properties, both involving the use of psychotropic drugs. Nondemented subjects were more commonly exposed to potential drug-disease interactions, mostly with the use of cardiovascular drugs. The most common drug combination leading to a potential interaction was the use of digoxin with furosemide, occurring more frequently among nondemented subjects. The most common drug-disease interaction was the use of beta-blockers and calcium antagonists in subjects with congestive heart failure. The doses of drugs taken by both nondemented and demented subjects were mostly lower than the defined daily dose. CONCLUSION: There was substantial exposure to presumptive inappropriateness of drug use in this very old nondemented and demented population. The exposure of demented subjects to psychotropic drugs and nondemented subjects to cardiovascular drugs reflect the high frequency of prescribing these drugs in this population.

Mental health promotion among community-dwelling seniors with multimorbidity : perspectives of seniors, district nurses and home care assistants
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The prevalence of mental illness is increasing among the older population in Sweden. One of the most vulnerable groups for mental health problems is older persons with multimorbidity, i.e. seniors with multiple chronic conditions. Many of them remain in their own homes with a comprehensive and complex need of support and healthcare, mainly provided by home care assistants (HCAs) and district nurses (DNs). However, the detection of mental health problems for adequate treatment or to promote mental health among community-dwelling seniors with multimorbidity, calls for skills and competences in this area.This thesis aimed to gain a deeper understanding of how mental health may be promoted among community-dwelling seniors with multiple chronic conditions. Four studies have been included in this thesis (I-IV). All studies had a qualitative descriptive design with either a phenomenographic approach or latent and manifest qualitative content analysis technique. The aim of study I was to describe the variations in how community-dwelling seniors with multimorbidity perceived the concept of mental health and what may influence it. The findings showed the participants conceptualised mental health as having both positive and negative facets. The participants further conceived that social contact, physical activity and optimism may improve mental health, while social isolation, ageing, and chronic pain may worsen it. Study II aimed to describe the experience of health-promoting dialogues from the perspective of community-dwelling seniors with multimorbidity, and what these seniors believed to be important for achieving a dialogue that may promote their mental health. The main finding was the necessity of being seen as a unique individual by an accessible and competent person. Further, the participants missed having friends and relatives to talk to and they especially lacked healthcare or social service providers for health-promoting dialogues that may promote mental health. The aim of study III was to describe DNs’ perspectives on detecting mental health problems and promoting mental health among community-dwelling seniors with multimorbidity. Findings revealed that the DNs’ focus was on assessment, collaboration and social support as a way of detecting mental health problems and promoting mental health. Study IV described HCAs’ perspectives on detecting mental health problems and promoting mental health among the seniors in focus. The findings revealed that continuity of care and the seniors’ own thoughts and perceptions were regarded as essential for the detection of mental health problems. Further, observation, collaboration, and social support emerged as important means of detecting mental health problems and promoting mental health.Conclusions: The results of this thesis are based on interviews and show that: 1) Seniors with multimorbidity should have an opportunity to describe how multiple chronic conditions may affect their life situation; 2) An optimal level of care can be achieved through continuity, involvement, and by providing a health-promoting dialogue based on the person’s wishes and needs; 3) Even if DNs seemed engaged in primary mental healthcare, there were no expressed goals set in the improvement of mental health, and it seemed that these DNs could not bear the primary responsibility for early detection of mental health problems and early interventions to improve mental health; 4) HCAs had knowledge about risk factors for mental health problems and it appears that they were dependent on care managers’ decision-making in granted support, as well as supervision from DNs in the detection of mental health problems and to promote mental health.In summary, the finding in the present thesis demonstrates that managing mental health problems is still an ongoing challenge for those organisations providing continuity in home care and home healthcare for homebound elderly persons with complex chronic conditions. The finding in the thesis also shows that DNs and HCAs seem to be dependent on each other in this area. Mental health promotion was expressed as an important assignment among DNs and HCAs, even though they describe different prerequisites and factors which could be seen as barriers in the detection of common mental health problems such as depression, anxiety and sleep problems. These personnel further described difficulties in collaboration and transmission of information between care- and healthcare providers from the community and primary care context. Social and physical interventions - as well as social contacts and social support to break social isolation - seemed important according to all the informants, with their different perspectives of how mental health may be promoted.

- The aim of this study was to evaluate the effect of a geriatric-anesthesiologic intervention program for the prevention and treatment of acute confusional states (ACS) in elderly patients treated for femoral neck fractures. The intervention program was based on the results of previous prospective studies in similar patient populations. The outcome of the intervention, comprising 103 patients, was compared with that of an earlier study comprising 111 patients. The intervention program consisted of pre- and post-operative geriatric assessments, oxygen therapy, early surgery, prevention and treatment of peri-operative blood pressure falls and treatment of post-operative complications. The incidence of ACS was lower, 47.6%, in the intervention study compared with 61.3% (P less than 0.05) in the control study. Furthermore, the ACS that occurred in the intervention study was less severe and of shorter duration than that in the control study. The incidence of post-operative decubital ulcers, severe falls, and urinary retention was also lower. The mean duration of orthopedic ward stay was 17.4 days in the control study and 11.6 days in the intervention study (P less than 0.001). It can be concluded that the intervention program reduced the incidence, severity, and duration of ACS which resulted in a shortened orthopedic ward stay

Acute confusional state (delirium) : clinical studies in hip-fracture and stroke patients
- 1991
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Acute confusional state (ACS) or delirium according to DSM-III-R holds a central position in the medicine of old age. ACS is a common and sometimes the only symptom of diseases and medical complications in the elderly patient.The aim of this study was to elucidate ACS in patients with femoral neck fractures and patients with acute stroke with regard to frequency, predictors, possible pathogenetic mechanisms, associated complications, assessment and documentary routines and the clinical outcome for the patients. An intervention program to prevent postoperative ACS based on our results was developed and evaluated.The main findings of the study were high frequencies of ACS in elderly patients with femoral neck fractures (61 %) and in patients with acute stroke (48 %). The main risk factors for ACS in patients with femoral neck fractures were old age, diseases and drug treatment interfering with cerebral cholinergic metabolism. There was no link between anaesthetic technique and ACS but the connection between peroperative hypotension, early postoperative hypoxia and ACS was close.In stroke patients the degree of extremity paresis and old age were independent ACS risk factors. ACS was commonly associated with post stroke complications such as myocardial infarction, pneumonia, urinary infection and urinary retention. In stroke patients there was a close connection between high hypothalamic-pituitary-adrenal axis (HPA-axis) activity and ACS. High HPA-axis activity and disturbances in the cerebral cholinergic system may be two important ACS mechanisms.A correct diagnosis is a prerequisite for proper treatment of ACS and its underlying causes. In the orthopaedic wards both physicians and nurses diagnosed and documented ACS poorly and therefore associated complications were insufficiently treated.The intervention program for postoperative ACS, aimed mainly at protecting the cerebral oxidative metabolism and thereby the cerebral cholinergic metabolism which is especially sensitive to hypoxia. Postoperative complications associated with ACS were also treated. The intervention resulted in reduced frequency, duration and severity of postoperative ACS and in shorter orthopedic ward stay for patients with femoral neck fractures.Key words: Acute confusional state, delirium, elderly

- The aims of this study were to estimate the incidence of acute confusional state (ACS), its predisposing factors and consequences in 111 consecutive patients operated for fractured neck of the femur. The incidence of ACS was 61 percent and the predicting factors were old age and dementia. Drugs with anticholinergic effect, depression, and previous stroke were factors that seemed to be associated with the development of ACS. Ninety-two percent of the patients who had severe perioperative blood pressure drops developed ACS. The consequences of ACS were prolonged ward-stay at the orthopedic department, a greater need for long-term care after discharge, and poor walking ability at discharge and six months after surgery. The confused patients also had more complications, such as urinary problems, feeding problems and decubital ulcers, as compared with the nonconfused patients.
