RESUMEN
BACKGROUND: Late-life depression is thought to differ in clinical presentation from early-life depression. Particularly, late-life depression is considered to be more characterized by apathy than is early-life depression. Lacking convincing evidence, this study examines the presence and associated socio-demographic/clinical characteristics of apathy in older compared to younger depressed persons. METHODS: This cross-sectional study used data from two naturalistic cohort studies, i.e. the Netherlands Study of Depression in Older Persons (NESDO) and the Netherlands Study of Depression and Anxiety (NESDA). These studies included 605 persons (aged 18-93 years) with a major depressive disorder, divided into 217 early-life (< 60 years) and 388 late-life (≥ 60 years) depressed persons. Apathy was considered present if a score of ≥14 on the Apathy Scale. RESULTS: Apathy was strongly associated with age: it was more frequently present in persons with late-life depression (74.5%) than in those with early-life depression (53.5%). Independent of age, the following characteristics were associated with the presence of apathy: male gender, low education, use of benzodiazepines, chronic diseases, and more severe depression. Of all potential risk factors, only former and current smoking was associated with the presence of apathy in older depressed persons but not in younger depressed persons (p-value for age interaction = 0.01). LIMITATIONS: No causal relationships can be drawn due to the cross-sectional design of the study. CONCLUSIONS: In depressed individuals, clinically relevant apathy was more frequently present in older compared to younger persons. Both age groups showed largely the same associated risk factors. Apathy was independently associated with older age, male gender and more severe depression.

OBJECTIVES: Apathy is a common behavioral syndrome, influencing different areas of daily functioning and often seen in depression. Little is known about the course of apathy in depression. In this study, we examine the course and predicting factors of apathy in older persons with depression. METHOD: Data of 266 older persons with depression participating in the Netherlands Study of Depression in Older Persons, all aged at least 60 years with complete Apathy Scale scores at baseline and 2-year follow-up, were included in this study. Associations between several baseline variables and severity, incidence, and persistence of apathy were examined using regression analyses. RESULTS: At 2-year follow-up, the severity of apathy was predicted by the severity of apathy at baseline, and incidence rate of apathy was 36%, with a lower baseline Mini-Mental State Examination score being an independent predictor. Older persons with incident apathy did not differ in remission rate of depression compared to those without apathy at follow-up. Persistence rate of apathy was 80% and was independently predicted by a higher baseline Apathy Scale score and, surprisingly, by less use of benzodiazepines. Persons with persistent apathy were less likely to recover from depression than those who remitted from apathy. CONCLUSION: Severity of apathy at baseline, but not depression, predicted apathy at follow-up. Incident apathy was predicted by poorer cognitive function, whereas severe apathy at baseline predicted its persistence. Remarkably, new apathy was not associated with worse outcome of depression whereas persistent apathy was.

OBJECTIVES: To identify clinically relevant subtypes of apathy in older persons using latent class analysis (LCA) and investigate the distribution of different characteristics across these subtypes. MEASUREMENTS: Cross-sectional data of 122 older persons (mean age 84 years, 60% female) participating in the general population-based PROactive Management Of Depression in the Elderly study, with apathy according to a score of 14 or higher on the Apathy Scale, were included for LCA. All 14 items of the Apathy Scale were used as indicator variables. Several characteristics were examined including sociodemographics, depressive, and anxiety symptoms; global cognitive function; quality of life indicators; hazardous alcohol intake (drinking ≥ 14 consumptions per week); and perceived chronic pain. RESULTS: Three distinct LCA classes were found classifying 17%, 7%, and 76% of the participants respectively. Individuals in the first class had a higher level of education and were less likely to live alone. Those in the second class had higher apathy and depression scores, lived more frequently alone and used more alcohol. Individuals in the third class showed a lower level of education and worse cognitive function. In multivariable multinomial analyses, only a lower educational level and higher scores on the Apathy Scale were significant predictors for class membership. CONCLUSION: Differences between LCA-derived classes were minimal, suggesting that in a general population-based cohort the Apathy Scale measures a homogeneous construct.

Background and Objectives: Apathy is a behavioral syndrome that often co-occurs with depression. Nonetheless, the etiology of apathy and depression may be different. We hypothesized that apathy occurs more often in depressed compared to non-depressed older persons; and that independent correlates for apathy will be different in depressed and non-depressed older persons. Methods: In this cross-sectional study of Netherlands Study of Depression in Older Persons (NESDO), a total of 350 depressed older persons according to the Composite International Diagnostic Interview (CIDI) and 126 non-depressed older persons, aged at least 60 years were recruited in several Medical Centres and general practices. In both depressed and non-depressed older persons, those with and without apathy as assessed with the Apathy Scale (score greater than or equal to 14) were compared with regard to socio-demographic, clinical, and biological characteristics. Results: Apathy was present in 75% of the depressed and 25% of the non- depressed older persons. Independent correlates of apathy in both depressed and non-depressed older persons were male gender and less education. Furthermore, in depressed older persons, higher scores on the Inventory of Depressive Symptomatology (IDS) and, in non-depressed older persons, a higher C-reactive protein (CRP) level correlated independently with apathy. Conclusions: Apathy occurred frequently among both depressed and non-depressed older persons. Among depressed older persons, apathy appeared to be a symptom of more serious depression, whereas among non-depressed persons apathy was associated with increased CRP being a marker for immune activation, suggesting a different a etiology for apathy in its own right (AU)

OBJECTIVE: To investigate the relationship between apathy and perceived quality of life in groups both with and without depressive symptoms or cognitive impairment. METHODS: We conducted a cross-sectional study comparing quality of life in older persons with and without apathy in 19 Dutch general practices. Participants were 1,118 older persons aged at least 75 years without current treatment for depression and a Mini-Mental State Examination score of at least 19. Perceived quality of life was determined using Cantril's Ladder for overall quality of life, EuroQol (EQ)-5D thermometer for subjective health quality, and De Jong-Gierveld Loneliness questionnaire for perceived loneliness. Apathy was assessed with the Apathy Scale. RESULTS: Of the 1,118 older persons, apathy was present in 122 (11%) of them. Overall, apathy was associated with having no work, lower level of education, presence of depressive symptoms, cognitive impairment, and decreased scores on all quality of life measures. Among the 979 (88%) older persons without depressive symptoms and cognitive impairment, apathy was present in 73 (7.5%) of them, showing similar associations as in the total population. In the 77 (7%) persons with cognitive impairment only, apathy was correlated to a lower score on the EQ-5D thermometer. However, in the 51 (5%) depressed persons without cognitive impairment, presence of apathy did not contribute to their decreased quality of life. CONCLUSION: Apathy frequently occurred in community-dwelling older persons, also in the absence of depressive symptoms and cognitive impairment. In them, apathy contributed to the perception of a diminished quality of life in various aspects of daily life.
