Background: Diabetes, cardiovascular disease and metabolic syndrome are more prevalent in older patients with severe mental illness (smi) than in healthy older persons in the same age-group as the smi patients. Compared to the general population, smi patients are often in a poorer state of (physical) health and have a shorter life expectancy.
AIM: To assess the value of screening older smi patients (≥ 60) for metabolic syndrome.
METHOD: We performed a prospective evaluation of the metabolic screening outcome data relating to 100 older smi patients and 124 healthy older patients and compared the results.
RESULTS: In our smi patients (average age 69 years; 52% bipolar disorder, 48% schizophrenia) the frequency of metabolic syndrome (43%) was no higher than in healthy older persons (39.5%, p = 0.60). However, in 51% of the smi sample, metabolic screening detected at least one metabolic abnormality in a patient with no previous history for that specific parameter.
CONCLUSION: By making routine metabolic screening available to a greater number of older smi patients, we should be able to identify substantial numbers of metabolic abnormalities that have been previously overlooked.

In The Netherlands no detailed information about alcohol consumption among older persons (55 years and older) is available. Therefore we investigated the prevalence and determinants of alcohol consumption with data from the Longitudinal Aging Study Amsterdam. The results show that 13.4% of persons of 55 years and older are heavy drinkers (male >3 glasses per day, female >2 glasses per day). Most heavy drinkers are younger than 75 years of age, and in this age group more female (22.2%) than male (14.8%) are heavy drinkers. 13% of all participants frequently drinks 6 or more glasses in a short period of time (binge drinking). In the age group of 55-65 years alcohol consumption has considerably increased over a period of ten years. This increase is stronger among females than among males. When people grow older alcohol consumption decreases, which seems associated with a decline in physical or psychological health and/or cognitive decline. Heavy and binge drinking is associated with younger age, higher education and income, and may be strongly related to their social lifes.

The aim of this research is to investigate the often assumed relation between alcohol use and depressive symptoms among older men and women. For this study, a subsample of 2119 participants of the Longitudinal Aging Study Amsterdam, aged 65 to 85 years at baseline, was followed over time and visited in their homes in 1992, 1995, 1998 and 2002. Depressive symptoms are assessed with the Centre for Epidemiologic Studies Depression Scale (CES-D). Alcohol use is measured with questions about the frequency and quantities of alcohol use. A relation between depressive symptoms and alcohol use could not be demonstraded in a population based sample of older drinkers. Only older heavily drinking men with higher levels of depressive symptoms, higher levels of anxiety, and more chronic diseases at baseline significantly reduced the number of glasses consumed per week from 26 to 14 in the ten years of follow-up. Heavily drinking women do not reduce the level of alcohol intake during follow-up. Public prevention strategies are needed to make older heavy drinking women and men who are still in relatively good health aware of the potential risks of excessive alcohol use.

Background: It has still not been established unequivocally whether vascular risk factors and inflammatory reactions, determined by heredity, are a cause or a result of Alzheimer's disease, Aim: If the offspring of parents with AD have more risk factors and more frequent and severe inflammatory reactions than the offspring of parents without AD , this argues strongly in favor of a causal relationship between vascular risk factors, a pro-inflammatory cytokine response and AD., Aim: To determine whether the offspring of parents with ad have more risk factors and more frequent and severe inflammatory reactions than the offspring of parents without ad. method Vascular risk-factors, pro-inflammatory cytokines and the apoe genotype were determined in 206 offspring of parents with ad and in 200 offspring of parents without AD., Results: Offspring of parents with ad carried more apoe epsilon4 than offspring of parents without ad (47% vs 21%). Middle-aged offspring of parents with a history of ad also had higher blood pressure and a greater atherosclerotic burden than the offspring of parents without AD. Also their response to the pro-inflammatory cytokine was significantly higher., Conclusion: Hypertension and an inherited pro-inflammatory cytokine profile in middle age are early risk factors that contribute to the development of ad in old age. Offspring with a parental history of AD should therefore be offered screening and treatment for hypertension and have their blood pressure checked so that the development of AD in old age can be prevented.

Background: Assessment of psychomotor symptoms may lead to better classification of depressive disorders., Aim: To test the inter-rater reliability of the Dutch version of CORE, an observational instrument for psychomotor symptoms., Method: The CORE was used with 37 depressed in-patients and was scored by 5 psychiatrists. Intra-class correlation (ICCagreement) was tested., Results: ICCagreement of the total score (0.80), and the subscales non-interaction (0.74), retardation (0.70) and agitation (0.79) were sufficient., Conclusion: The Dutch version of the CORE is a reliable instrument.

Alexithymia (cognitive and affective emotion regulation) may be important for understanding mood disorders in older adults. In the present study it is examined whether alexithymia (i) acts as a stable personality trait, (ii) is independent from the Big Five personality traits, and (iii) is associated with the course and outcome of depressive disorder. Alexithymia was assessed at intake and after three months in older adults with a (sub)clinical depressive disorder using the The Bermond Vorst Alexithymia Questionnaire (BVAQ). The results show that alexithymia acts as a stable and independent personality trait. Alexithymia was no predictor for the outcome of depression after three months. It was concluded that alexithymia should be considered when assessing and treating depression in older adults. However, further research is necessary.

In this article, a report is provided of results from the Longitudinal Aging Study Amsterdam (LASA). LASA is a study on determinants and consequences of changes in daily functioning. In this article, the focus is on changes in physical functioning. From longitudinal data, it is observed that many older people experience function loss, especially at higher ages. A host of factors are associated with function loss, such as chronic diseases, cognitive decline, depressive complaints, socio-economic status, and life style. A few of these factors are causal, others are characteristics of groups with raised chances of function loss. From trend analyses, it is apparent that the prevalence of functional limitations is not fixed, but varies over time. The LASA study shows that this prevalence is increasing. In view of the absolute and relative rise of the number of older people in the population, it is of great importance to realise a lower prevalence of function loss and a delay of function loss to older ages. Based on the findings presented, some suggestions for this are given. Also, some directions for future research are described.

Cognitive decline without dementia is common among older persons. A variety of clinical concepts have been introduced in the past 30 years, in order to describe these cognitive deficits arising in older persons. The most frequently used concept is Mild Cognitive Impairment (MCI). MCI is generally seen as a prodromal phase of Alzheimer disease (AD). Several concepts are described, with the neuropsychiatric features and predictors of conversion to dementia c.q. AD. Finally, consequences of preclinically diagnoses for health care are clarified.

In order to identify persons who are at risk for dementia in an early phase, two classification trees were developed. Data were used from the Longitudinal Aging Study Amsterdam (LASA). The prevalence of dementia in the whole sample was 4.0%. In the first tree age seemed to be the strongest predictor, with an increased risk for persons older than 75. In this group the positive predictive value reached a maximum of 33.3% when the persons had memory complaints and a score on the Mini Mental State Examination (MMSE) <24. In a second classification tree, age was excluded as a predictor because of high association with the other potential predictors. In this tree functional limitations seemed the strongest predictor. In the group of persons with at least one functional limitations, the positive predictive value reached a maximum of 28.8% when the persons had memory complaints and a score <24 on the MMSE. In persons without memory complaints, persons with cardiovascular diseases or diabetes were at increased risk of dementia. Further research is necessary before these classification trees can be implemented in general health care.

The relation of aging and the stability of personality in late life is evaluated by a literature review. The findings of six longitudinal studies reveal that rank-order consistency continues into old age. The mean-level stability reveals a concave curve for 'neuroticism' with an increase after age 80, a decrease for 'extraversion', and an increase for 'agreeableness'. The methodological and conceptual issues of personality assessment with old adults can be resolved by using a self report scale which corresponds to the capacities and the lifestyle of older adults and by involving age related variables into analyses.

Apathy is defined as a disorder of motivation that expresses itself at an emotional, cognitive and behavioural level. Apathy can occur as a symptom and a syndrome. In the recent years diagnostic criteria and a number of scales for measuring apathy in elderly with psychiatric or neurological disorders have been introduced. Two scales are specifically developed to measure apathy, the Apathy Evaluation Scale (AES) from Marin and the Apathy Scale (AS) from Starkstein. Both scales have been translated into Dutch. The AS is more convenient. The AS in addition can be used when applying the criteria for the apathy syndrome which has been introduced in 2001 by Starkstein. In addition, the Neuropsychiatric Inventory (NPI) and the 'Gedragsobservatieschaal voor de Intramurale Psychogeniatrie' (GIP) (a scale in Dutch) have an apathy domain. Conceptual problems surrounding apathy have only partly been resolved. The criteria for the apathy syndrome can only be used for assessing the extent of the problem. Apathy and depression are strongly correlated. Studies show that apathy as a syndrome can occur without concomitant depression in the elderly, but regularly occurs besides a depressive disorder, in percentages varying between 9% and 53% of the population under study. Especially the varying validity of an apathy syndrome in relation to late life depression needs further clarification.

In this article methods are discussed which may keep participation in a longitudinal study among elderly persons high, for example adaptation of the interviews and proxy interviews. The LASA sample is described from the start in 1992 until now. The non-response is evaluated and we found that refusals are particularly important in the first part of the longitudinal traject. Also data quality is studied in relation to the aging of the respondents. Although there are theoretical reasons to expect that aging may impair data quality, no support for this hypothesis was found in the present study. Data quality was stable during a period of six years. But data quality seemed poorer for those respondents who dropped out from the study. Item non-response and duration of the interview were higher for drop-outs.
