Background: Alzheimer's disease (AD) is associated with dependence in activities of daily living (ADL). In addition to the cognitive impairment resulting from AD, the presence of psychotic symptoms may further increase this dependence. The objective of this study was to quantify the additional contribution of psychotic symptoms to dependence in ADL. Method: We analyzed data from 558 individuals with AD referred to a memory clinic. Information on ADL, psychotic symptoms, depression symptoms, and cognition was collected with standardized instruments. Results: The frequency of psychotic symptoms was correlated with dependence in ADL (r = −.44, p < .001). The independent contribution of psychotic symptoms to ADL (basic and instrumental) after consideration for cognitive impairment and depression symptoms was assessed with hierarchical regression models. Twenty-five percent of basic ADL variance was explained by cognition; psychotic symptoms accounted for an additional 7% of the variance (b = −0.12, p < .001). Cognitive impairment explained 31% of instrumental ADL variance; psychotic symptoms accounted for an additional 6% (b = −0.21, p < .001). Discussion: Psychotic symptoms are associated with dependence in ADL after controlling for cognitive impairment and depression symptoms. Future research should investigate possible causal linkages between psychotic symptoms and dependence in ADL. This may have implications regarding interventions to maintain independent living in people with AD.

Background: Alzheimer's disease (AD) places a significant burden on health care systems worldwide. As new treatments are developed, their cost-effectiveness is often assessed to help health care professionals make informed decisions. In addition to the more common practice of assessing direct medical costs, indirect costs, including time spent in caregiving, should be evaluated. Methods: This study examined the potential effects of the dual cholinesterase inhibitor rivastigmine (Exelon) on caregivers of patients with AD. Results from two 26-week, placebo-controlled trials have demonstrated the clinically relevant and statistically significant efficacy of rivastigmine (6–12 mg/day) compared to placebo, on cognition, activities of daily living, and global functioning. By delaying progression of AD, significant savings in caregiver burden are anticipated, as measured by time spent caregiving and its related costs. Data collected in a prospective, observational study of AD patients and their caregivers were used to establish the relationship between disease severity (based on Mini-Mental State Examination [MMSE] score) and time spent caregiving (according to the 5-item Caregivers Activity Survery score). A significant correlation was observed between the two scores (N = 43, r = −.56, p < .0001), demonstrating that more time for supervision from caregivers is required as the disease progresses. This finding was used to estimate the reduced caregiver burden resulting from the delay in disease progression that was demonstrated with use of rivastigmine. Results: Over a 2-year period, the reduction in time spent in caregiving reached 691 hours for caregivers of patients with mild AD (MMSE score 21–30), resulting in a total savings of approximately $11,253. Treatment of patients with moderately severe AD was also evaluated. The trend was similar but the impact was less, suggesting an economic benefit to early therapy. Conclusion: Early diagnosis and a pharmacologic intervention that allows the patients to remain at home longer by delaying disease progression would have a beneficial impact on patients, caregivers, and payers, and should therefore be encouraged through initiatives designed to identify and treat patients early in the course of disease.

In cerebrovascular disease of all kinds, the white matter bears a heavy burden – particularly in the early and late periods of life. The infarcts are of the complete and incomplete type, the latter accompanying and extending the white-matter damage of the former. Complete infarcts are mainly caused by vascular occlusions. Incomplete infarcts are mainly due to hypoperfusion, wherein pathogenic factors are, above all, different types of angiopathies leading to an inadequate autoregulatory response in the event of an episodic or more longstanding hypotension, acting as an etiological factor through hypoperfusion. There is growing consensus that white-matter lesions affect brain function. Correlation with symptoms and understanding of mechanisms behind the lesions would gain from more precise diagnostics as to tracts involved.

Increased sexual activity in patients with dementia is problematic for caregivers and has no proven treatment. This report decribes two male patients who had dementia with pronounced sexual acting out. One patient had vascular dementia and the other patient had Parkinson's disease with associated dementia. After nonresponse to neuroleptics and sedatives, low-dose cyproterone acetate successfully reduced sexual acting out without relevant side effects in both patients.

Objective: To determine the attitudes of patients with mild dementia and their carers towards the disclosure of diagnoses of cancer and dementia and whether there are differences between these groups. To determine whether any major adverse events occurred following disclosure of diagnosis of dementia. Design: A prospective study followed by a retrospective case-note study after 1 year. Participants and Setting: Fifty patients with mild dementia and their carers were recruited from a memory clinic in Nottingham, UK, and an old-age psychiatrist, using a semistructured questionnaire, separately interviewed them. Measures: Questions related to whether patients and their carers wished to be told diagnoses of cancer and dementia; the reasons for this; whether they would want treatment and make use of predictive testing if available were included. At 1-year follow-up whether antidepressants had been prescribed and whether any catastrophic reaction had occurred following disclosure of diagnosis. Results: An overwhelming majority of patients with mild dementia wished to be informed of their diagnosis (92%); even more (98%) of the same patient sample reported wanting disclosure of a hypothetical diagnosis of cancer. A higher proportion (98%) of carers would wish to be told if they were to develop either dementia or cancer. All patients and carers would like access to treatment for dementia. A total of 88% of patients and 86% of carers would make use of a predictive test of Alzheimer's disease. Before receiving a diagnosis of mild dementia, only 28% of patients had insight that they may have dementia. Only a quarter (26%) of carers did not want the doctor to disclose the diagnosis of dementia to the patient. After 1 year, 6% of the original sample had developed a depressive illness requiring antidepressant treatment and no major incidents had occurred following disclosure of diagnosis. Conclusions: There has been a growing debate on whether patients with dementia should be informed of their diagnosis. Until recently, little was known about the views of patients themselves. This study shows that the vast majority of patients with mild dementia wish to be fully informed. Despite increasing awareness, a quarter of carers still do not wish their relative to be informed, though wish to be informed if they themselves were to develop the illness. This is significantly lower, however, than previously reported, suggesting a shift in attitudes. This study adds support to the weight of evidence that disclosure of a diagnosis of dementia does not cause depression or any irreversible harm to the patient.

Background: The Neuropsychiatric Inventory (NPI) has been used to assess behavioral symptoms of dementia in the United States, Taiwan, Japan, and Italy. Method: This report evaluates the use of the NPI to assess behavioral symptoms of dementia in a population of Yoruba, Nigerians aged 65 years and older who are subjects in the Indianapolis-Ibadan Dementia Project. In this study, the NPI, Blessed Dementia Scale, and Mini-Mental State Examination (MMSE) were used to assess Nigerian subjects with dementia. For this study the NPI was translated, back translated, and harmonized into Yoruba. Results: The harmonized version of the NPI showed good interrater and test-retest reliability. The Cronbach alpha on 40 subjects was .80 for total severity score, .73 for frequency, and .73 for distress, indicating good internal consistency. The MMSE correlated with the NPI total score and severity scores of delusion, hallucination, and agitation, whereas the Blessed correlated with the NPI total score and severity scores of depression, anxiety, and nighttime behavior. Conclusions: The NPI was found to be a reliable tool to assess behavioral symptoms and caregiver distress of dementia in the Yoruba. Behavioral disturbances were as common in the Yoruba patients with dementia as in studies in other countries that have used the NPI, but the pattern of behavioral disturbances and caregiver response varied among the countries.

In this article we report the first series of Turkish inpatients with late-onset psychosis, and describe our 9-year experience at the only inpatient geriatric psychiatry department in Turkey. Among 420 patients hospitalized between 1993 and 2002, 27 were psychotic. In this group, eight patients were diagnosed as having late-onset schizophrenia (LOS) and six very-late-onset schizophrenia-like psychosis (VLOSLP). Five patients had early-onset schizophrenia and eight had delusional disorder. Females were more frequently seen in the group with LOS and the group with VLOSLP. Except for one patient with LOS, all patients with VLOSLP and LOS had paranoid psychosis. Nihilistic delusions, delusions of poverty or guilt, thought withdrawal, thought insertion, and thought broadcasting were not seen in any of the patients. Additionally, none of the LOS or VLOSLP patients showed erotomanic delusions. Grandiose and mystic delusions were not seen in those with VLOSLP. Treatment results and antipsychotic dosages at discharge were similar to those in previous reports from other cultures.

Although a high prevalence of overweight is present in elderly people, the main concern in the elderly is the reported decline in food intake and the loss of the motivation to eat. This suggests the presence of problems associated with the regulation of energy balance and the control of food intake. A reduced energy intake causing body weight loss may be caused by social or physiological factors, or a combination of both. Poverty, loneliness, and social isolation are the predominant social factors that contribute to decreased food intake in the elderly. Depression, often associated with loss or deterioration of social networks, is a common psychological problem in the elderly and a significant cause of loss of appetite. The reduction in food intake may be due to the reduced drive to eat (hunger) resulting from a lower need state, or it arises because of more rapidly acting or more potent inhibitory (satiety) signals. The early satiation appears to be predominantly due to a decrease in adaptive relaxation of the stomach fundus resulting in early antral filling, while increased levels and effectiveness of cholecystokinin play a role in the anorexia of aging. The central feeding drive (both the opioid and the neuropeptide Y effects) appears to decline with age. Physical factors such as poor dentition and ill-fitting dentures or age-associated changes in taste and smell may influence food choice and limit the type and quantity of food eaten in older people. Common medical conditions in the elderly such as gastrointestinal disease, malabsorption syndromes, acute and chronic infections, and hypermetabolism often cause anorexia, micronutrient deficiencies, and increased energy and protein requirements. Furthermore, the elderly are major users of prescription medications, a number of which can cause malabsorption of nutrients, gastrointestinal symptoms, and loss of appetite. There is now good evidence that, although age-related reduction in energy intake is largely a physiologic effect of healthy aging, it may predispose to the harmful anorectic effects of psychological, social, and physical problems that become increasingly frequent with aging. Poor nutritional status has been implicated in the development and progression of chronic diseases commonly affecting the elderly. Protein-energy malnutrition is associated with impaired muscle function, decreased bone mass, immune dysfunction, anemia, reduced cognitive function, poor wound healing, delayed recovery from surgery, and ultimately increased morbidity and mortality. An increasing understanding of the factors that contribute to poor nutrition in the elderly should enable the development of appropriate preventive and treatment strategies and improve the health of older people.

Cerebral small-vessel alterations play a central role in determining lesions of subcortical structures and eventually may lead to cognitive impairment. Small-vessel diseases are classified according to the pathological viewpoint. The most important ones are the changes in small arteries and arterioles caused by prolonged hypertension. These small-vessel changes may result in ischemic damage to the brain parenchyma and blood-barrier alterations. Both mechanisms are thought to contribute to the occurrence of white-matter changes and lacunar infarcts. Modern magnetic resonance techniques such as diffusion, perfusion, and spectroscopy may allow the in vivo study of the pathophysiology of small-vessel diseases and the consequences on the brain parenchyma.

Objective: The aim of this study was to determine whether indirect self-destructive behaviors predict mortality in nursing home residents. Method: This cross-sectional study with follow-up after 2 years and 3 months surveyed 593 residents in 10 nursing homes in the eastern suburbs of Sydney, Australia. The following instruments were used: Harmful Behaviors Scale (HBS), Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD), Functional Assessment Staging Scale, Resident Classificatin Index, Cumulative Illness Rating Scale, Even Briefer Assessment Scales for Depression, and the suicide item from the Structured Hamilton Depression Rating Scale. Diagnoses of depression, dementia, and psychosis were obtained from nursing home records. Mortality data were obtained in August 1999. Results: At follow-up, 297 (50.1%) residents were still alive with a mean survival time of 565.4 days. Survival analyses found that mortality was predicted by older age, male gender, lower level of functioning, lower levels of behavioral disturbance on the BEHAVE-AD, and higher scores on the HBS “passive self-harm” factor-based subscale, which includes refusal to eat, drink, or take medication. Discussion: These results suggest that passive self-harm behaviors predict mortality in nursing home residents.

Background and Aim: Previous research suggested caregiver singing could influence persons with severe dementia to communicate with increased competence, to cease aggression, and to cease disruptive screaming, while at the same time they seemed to understand what was going on when being cared for during morning care sessions. The aim of this study was to illuminate the posture, body movements, and sensory awareness of patients with dementia during three types of morning care sessions with professional caregivers: (a) the usual morning care situation, (b) a caring session in which familiar background music was played, and (c) a caring session in which the caregiver sang to and/or with the patient throughout. Nine patients with late-stage dementia and 5 professional caregivers participated in this study, and 27 sessions were videotaped (9 patients x 3 caring situations). Data Collection and Method: Data collection was done by means of video recording and the data were analyzed using qualitative content analysis. Results: During the usual caring situation, patients demonstrated slumped posture, sluggish and asymmetric motion, listlessness, minimal awareness of both egocentric space and the physical environment, and a poor ability to perform to completion activities necessary for personal care. Both background music playing and caregiver singing had strong influences on the body and on sensory awareness. Patients had straightened posture, stronger and more symmetric movements, and a greatly increased awareness of themselves and their environment. Patients appeared to regain skills necessary for daily living, and demonstrated that they could perform tasks with intention, purpose, and competence. Caregiver singing, in particular, was very effective at drawing out capabilities that appeared to be lost in these patients. In addition, caregiver singing elicited a larger degree of mutuality in the interaction between patient and caregiver than was seen with background music. Discussion: These results provide further support for the use of caregiver singing in dementia care, and the findings on how caregiver singing can be used to help in dementia caring situations are discussed.

Objective: To determine correlates of hoarding behavior in frail elderly persons. Methods: Information about nursing home residents (n = 408) and community-dwelling senior day-care participants (n = 177) was gathered through interviews with family and professional caregivers, medical chart review, and physician examinations, and included the following areas of assessment: hoarding behavior, demographic and health information, level of cognitive functioning, activities of daily living (ADL) performance, depressed affect, social functioning, manifestations of agitated behaviors, and previous stressful life experiences. Results: We found that 15% of the nursing home residents and 25% of the community-dwelling senior day-care participants manifested hoarding behavior at a rate of several times a week or higher. For nursing home residents, hoarding behavior was significantly related to a larger appetite, taking fewer medications, higher social functioning, comparatively less ADL impairment, and manifestations of physically nonaggressive agitated behaviors. For senior day-care participants, hoarding behavior was significantly associated with being female, a larger appetite, comparatively less gait impairment, fewer medical diagnoses, more involvement in activities, a positive diagnosis of dementia, hallucinations, the delusion of infidelity, and manifestations of three syndromes of agitated behaviors. Conclusion: While hoarding behavior in our samples presents differently from compulsive hoarding described in the literature, we obtained robust findings that show that despite differences in living conditions, the elderly persons who manifested hoarding behavior were those with relatively fewer health and functional disabilities. In addition, those who exhibited hoarding behavior also manifested agitated behaviors. We suggest that future researchers develop alternative measures of hoarding behavior so as to further clarify the phenomenon of hoarding behavior in the elderly.

Diseases of small cerebral blood vessels are heterogeneous in etiology and manifestations. Lipohyalinosis, venous collagenosis, amyloid angiopathy, and CADASIL affect different populations of blood vessels. Large and small hemorrhages, lacunae, cortical microinfarcts, and leukoaraiosis are the most important consequences of the small vessel angiopathies. Altered permeability as well as ischemia may be involved in the pathogenesis of the latter.

Aggressive behavior in dementia often has a severe impact on the quality of life of the patient and the caregivers, and is therefore important to handle. The strategy of treatment should be broad. Nonpharmacological interventions, including environmental adjustments and supporting and training the caregivers, should always be considered. Pharmacological treatment of aggressive behavior in patients with dementia often includes the use of neuroleptics. The atypical compounds clozapine, risperidone, and olanzapine have been shown to have an effect on aggressive behavior at low dosage with limited extrapyramidal side effects. The anticonvulsants carbamazepine and sodium valproate are further alternatives. In treatment-resistant cases, buspirone or lithium may be tried, although the effect of these substances on aggressive behavior in dementia has not been well established. In the end, however, a considerable degree of aggressive behavior sometimes remains after careful treatment trials, particularly in patients with severe aggressive behavior. In addition, treatment is sometimes limited by side effects.
