This study investigated the relationship of executive impairment and heart disease burden to remission of major depression among elderly patients. A total of 112 elderly subjects suffering from major depression received treatment with citalopram at a target daily dose of 40 mg for 8 weeks. Diagnosis was assigned using the Research Diagnostic Criteria and the DSM-IV Criteria after an interview with the Schedule for Affective Disorders and Schizophrenia. Executive dysfunction was assessed with the Initiation/Perseveration subscale of the Dementia Rating Scale (DRS) and the Color-Word Stroop test. Medical burden, including heart disease burden, was rated with the Cumulative Illness Rating Scale, and disability with Philadelphia Multilevel Instrument. Both abnormal initiation/perseveration and abnormal Stroop scores were associated with low remission rates of geriatric depression. Similarly, heart disease burden and baseline severity of depression also predicted low remission rates. The relationship of heart disease burden to remission was not mediated by executive dysfunction. Impairment in other DRS cognitive domains, disability, medical burden unrelated to heart disease did not significantly influence the outcome of depression in this sample. Executive dysfunction and heart disease burden constitute independent vulnerability factors that increase the risk for chronicity of geriatric depression. The findings of this study provide the rationale for investigation of the role of specific frontostriatal-limbic pathways in predisposing to geriatric depression or worsening its course.

Quality of life is an important indicator in assessing the burden of disease, especially for chronic conditions. The Health Utilities Index (HUI) is a recently developed system for measuring the overall health status and health-related quality of life (HRQL) of individuals, clinical groups, and general populations. Using the HUI (constructed based on eight attributes: vision, hearing, speech, mobility, dexterity, cognition, emotion, and pain/discomfort) to measure the HRQL for chronic disease patients and to detect possible associations between HUI system and various chronic conditions, this study provides information to improve the management of chronic diseases. This study is of interest to data analysts, policy makers, and public health practitioners involved in descriptive clinical studies, clinical trials, program evaluation, population health planning, and assessments. Based on the Canadian Community Health Survey (CCHS) for 2000-01, the HUI was used to measure the quality of life for individuals living with various chronic conditions (Alzheimer/other dementia, effects of stroke, urinary incontinence, arthritis/rheumatism, bowel disorder, cataracts, back problems, stomach/intestinal ulcers, emphysema/COPD, chronic bronchitis, epilepsy, heart disease, diabetes, migraine headaches, glaucoma, asthma, fibromyalgia, cancers, high blood pressure, multiple sclerosis, thyroid condition, and other remaining chronic diseases). Logistic Regression Model was employed to estimate the associations between the overall HUI scores and various chronic conditions. The HUI scores ranged from 0.00 (corresponding to a state close to death) to 1.00 (corresponding to perfect health); negative scores reflect health states considered worse than death. The mean HUI score by sex and age group indicated the typical quality of life for persons with various chronic conditions. Logistic Regression results showed a strong relationship between low HUI scores (< or = 0.5 and 0.06-1.0) and certain chronic conditions. Age- and sex-adjusted Odds Ratio (OR) and p values showed an effect among individuals diagnosed with each chronic disease on the overall HUI score. Results of this study showed that arthritis/rheumatism, heart disease, high blood pressure, cataracts, and diabetes had a severe impact on HRQL. Urinary incontinence, Alzheimer/other dementia, effects of stroke, cancers, thyroid condition, and back problems have a moderate impact. Food allergy, allergy other than food, asthma, migraine headaches, and other remaining chronic diseases have a relatively mild effect. It is concluded that major chronic diseases with significant health burden were associated with poor HRQL. The HUI scores facilitate the measurement and interpretation of results of health burden and the HRQL for individuals with chronic diseases and can be useful for development of strategies for the prevention and control of chronic diseases.

Epidemiologic evidence has linked elevation of serum homocysteine to an increased risk of coronary artery disease, stroke, and dementia. An increase in homocysteine levels in Parkinson disease (PD) recently has been discovered. Although B vitamin status and genetic factors are important modifying influences determining the degree of this elevation, the main cause appears to be therapy with L-dopa. It has been suggested that breakdown of L-dopa by catechol-O-methyltransferase results in increased homocysteine formation. Therefore, there are reasons to suggest that management of PD may render patients at increased risk of stroke, heart disease, dementia, and even accelerated nigral degeneration. At present, no controlled prospective studies have evaluated this phenomenon, although they are ongoing.

In the present paper we discuss two issues about relationships between congestive heart failure and the brain. First, major acute cerebrovascular events are very frequent among elderly people, but stroke does not appear to be frequently associated with congestive heart failure. Second, some cardiovascular conditions may determine progressive damage of cerebral tissue, with consequent impairment of cognitive functions. The association of cognitive impairment and cardiovascular diseases may dramatically increase morbility and mortality risks in the elderly. Recent studies seem to show that hypotension and congestive heart failure are risk factors for dementia in elderly people. In view of this data, an Italian multicentric study on congestive heart failure in hospitalized elderly patients (CHF Italian Study I) included a brief screening of cognitive abilities (MMSE). The presence of congestive heart failure induced a significant decrease of MMSE scores: mean MMSE score after statistical adjustment for the other variables was about one point lower in patients with congestive heart failure respect to elderly patients affected by heart disease but without congestive heart failure. A novel multicentric study (CHF Italian Study II) has been performed to identify cognitive functions more specifically impaired during congestive heart failure in the elderly. Preliminary data relative to 385 patients, confirmed that congestive heart failure may induce a generalized impairment of cognitive functions. These data have relevant clinical implications because they demonstrate that a multidisciplinary approach is necessary in these patients, both for prevention and rehabilitation therapy.

We investigated the influence of brain atrophy and white matter lesions on cognitive function in elderly people. We selected 33 subjects (mean age, 79.2 +/- 5.1yrs) with a MMSE score from 14 to 30 who had no previous history of stroke from the outpatients in the Memory Clinic of our hospital. These subjects were divided into four groups on the basis of their MMSE score as follows: 14-20; moderate dementia (Moderate-D, n = 9), 21-23; mild dementia (Mild-D, n = 9), 24-27; mild cognitive impairment (MCI, n = 10), 28-30; normal (Normal, n = 5). Among these four groups, we compared the frequency of the associated risk factors for cerebral infarction (hypertension, diabetes mellitus, hyperlipidemia, heart disease), and the severity of brain atrophy and cerebral white matter lesion which were visually evaluated by MRI technique. Brain atrophy and white matter lesions were assessed by reviewing the cerebral cortex and hippocampus, and deep white matter lesion (DWML) and periventricular hyperintensity (PVH), respectively. Brain atrophy was divided into three grades (mild, moderate, severe) and white matter lesions were classified into four grades (0-3) using Fazekas's criteria. We performed statistical analysis to detect t parameters which correlate with and influence MMSE scores from among the MRI findings. The cases with dementia were all diagnosed as Alzheimer's disease. There were no significant differences among the four groups in mean age, the incidence of individual associated risk factors, the severity of cortical atrophy, or the grade of DWML (< or = 2) and PVH (< or = 2). However, the frequency of hippocampal atrophic change greater than a moderate grade increased in parallel with the exacerbation of reduced cognitive function (Normal; 20%, MCI: 40%, Mild-D; 56%, Moderate-D 89%), and approximately 76% with such a change were AD cases. Statistical analysis showed a significant negative correlation between the grade of hippocampal atrophy and MMSE score (r = -0.518, p < 0.005) and a great influence of hippocampal atrophy on that score (step-wise regression analysis: r = 0.518, p < 0.005). From the above results, it was suggested that more than moderate atrophic change in the hippocampus might possibly be related with cognitive impairment and that both DWML and PVH less than the second grade had little influence on the decline of brain function.

Clinical trials show that hormone therapy (HT) is an effective treatment for vasomotor symptoms and vaginal dryness. HT improves other symptoms including sleep and quality of life in women who have menopause symptoms. In the Women's Health Initiative controlled clinical trials, both estrogen therapy (ET) and estrogen plus progestin therapy (EPT) reduced fracture risk, neither reduced the risk of heart disease, and both increased the risk of stroke, deep vein thrombosis, and dementia. EPT, but not ET, increased breast cancer risk and reduced colon cancer risk. Differences between EPT and ET may reflect chance, baseline differences between the EPT and ET cohorts, or a progestin effect. Studies of younger women and lower HT doses with intermediate endpoints are beginning.

Dementia, a diagnostic syndrome that includes Alzheimer's disease (AD) and vascular dementia, affects more than 4 million Europeans. Its prevalence will increase as the population ages, even though half of cases remain undiagnosed. Dementia has a marked impact on the general health economy. The direct costs of caring for persons with AD alone exceed the cost of heart disease, cancer and stroke combined, primarily because of the need for expensive care in the later stages of the disease. Yet research spending for AD remains disproportionately small. Effective planning for the public health issues posed by AD mandates reduction of either the dependency or the prevalence of the disease. Some drug treatments have alleviated the symptoms of AD and improved the quality of life for patients and their families. However, many countries have introduced inappropriately stringent regulations for the use of medical therapy. These and related issues were addressed during the recent Facing Dementia Forum, in which 175 experts in dementia care discussed results of an extensive international survey. The experts identified three main barriers to effective care: (i) dementia is not considered a health care priority; (ii) there is a mistaken belief that nothing can be done about dementia; and (iii) early dementia is difficult to recognise. These observations provided a basis for the Agenda for Change, a series of strategies to overcome these barriers. The specific findings of the survey, as well as the Agenda for Change, will be reviewed in subsequent articles in this supplement.

A progressive chain of pathophysiological events links cardiovascular risk factors to clinical manifestations of disease and life-threatening cardiovascular events. This chain--the cardiovascular continuum--underlies cardiovascular disease and holds the key to its prevention and treatment. Progressive tissue damage can result in morbidity from congestive heart failure, end-stage heart disease, nephrotic proteinuria and dementia and, eventually, death from cardio- or cerebrovascular causes. The renin-angiotensin-aldosterone system (RAAS) is involved at all stages of the cardiovascular continuum, because the effector molecules of the RAAS, angiotensin II in particular, have direct pathobiological effects on a variety of tissues, including the endothelium, vascular smooth muscle and the renal mesangium. Clinical trials of angiotensin II receptor blockers (ARBs) and angiotensin-converting enzyme (ACE) inhibitors have demonstrated the essential validity of this hypothesis. Interruption of the RAAS has been shown to reduce cardiovascular morbidity and mortality in patients with left ventricular hypertrophy, heart failure and post-myocardial infarction, as well as renal disease in patients with type 2 diabetes. Key questions remain, however. What are the clinical effects of combination ARB and ACE inhibitor treatment? How will combinations of RAAS blockade with other agents, such as statins, affect the cardiovascular continuum? Answers to these questions will require well-planned, adequately powered clinical trials, such as the Programme of Research tO evaluate Telmisartan End-organ proteCTION (PROTECTION) and the ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET) programmes. However, it is already clear that RAAS blockade is an essential part of blocking progression along the cardiovascular continuum.

Pathologically, Binswanger's disease is subcortical periventricular leucoencephalopathy sparing the U fibers. Clinically it is characterised by executive dysfunction, gait problems, urinary incontinence, pseudobulbar palsy, mood disturbances and dementia. The pathomechanism of Binswanger's disease is unclear. It is hypothesized that it results from an ischemic-hypoxic injury of the periventricular white matter, which, in turn, can be caused by a sclerotic elongation of the medullary arteries, widening of the perivascular spaces or decreased brain perfusion due to hypotension or heart disease. The symptoms of Binswanger's disease frequently overlap with those of normal pressure hydrocephalus, vascular parkinsonism and Alzheimer's disease. A diagnostic criterion of Binswanger's disease is radiologically demonstrated leukoaraiosis, which, on the other hand, is not equivalent with Binswanger's disease. A good clinical response after lumbar puncture or shunt implantation might lead to confusion with normal pressure hydrocephalus, which further complicates the clinical diagnosis. It is likely that among the above mentioned disorders there are a number of transitional forms and overlaps, which might be explained by the common pathomechanism of disturbance in cerebrospinal fluid circulation.

This study assessed clinical, demographic, facility, and regional factors associated with documented do-not-resuscitate (DNR) orders, feeding/medication/other treatment (FMT) restrictions, and living wills among nursing facility residents. Using the Nursing Home Component of the 1996 Medical Expenditure Panel Survey, a nationally representative sample of 815 facilities and 5899 residents, three separate multivariate logistic regression models were developed. DNR orders were more prevalent among residents aged 75+ and those with severe cognitive impairment, dementia, emphysema, and cancer, but less common among African Americans and Latinos than whites. Residents with living children were more likely to have DNR orders. Latinos were less likely to have FMT restrictions. Living wills were more common among residents aged 75+ and those with psychiatric/mood disorders and heart disease, but less prevalent among African Americans. Residents with less social engagement and household incomes below 400% of the Federal Poverty Level were less likely to have a living will. Residents with Medicaid as their largest payer were less likely to have an advance care plan than those with Medicare or other payment mechanisms. To increase the use of advance care plans, interventions should focus on groups with less social engagement and lower household income.
