Neuropsychological test performance and prediction of functional capacities among Spanish-speaking and English-speaking patients with dementia.

Neuropsychological measures have been widely used by clinicians to assist them in making judgments regarding a cognitively impaired patient's ability to independently perform important activities of daily living. However, important questions have been raised concerning the degree to which neuropsychological instruments can predict a broad array of specific functional capacities required in the home environment. In the present study, we examined 127 English-speaking and 56 Spanish-speaking patients with Alzheimer's disease (AD) and determined the extent to which various neuropsychological measures and demographic variables were predictive of performance on functional measures administered within the clinical setting. Among English-speaking AD patients, Block Design and Digit-Span of the WAIS-R, as well as tests of language were among the strongest predictors of functional performance. For Spanish-speakers, Block Design, The Mini-Mental State Evaluation (MMSE) and Digit Span had the optimal predictive power. When stepwise regression was conducted on the entire sample of 183 subjects, ethnicity emerged as a statistically significant predictor variable on one of the seven functional tests (writing a check). Despite the predictive power of several of the neuropsychological measures for both groups, most of the variability in objective functional performance could not be explained in our regression models. As a result, it would appear prudent to include functional measures as part of a comprehensive neuropsychological evaluation for dementia.

Deterioration of functional capacities in Alzheimer's disease after a 1-year period.

There is a paucity of data regarding Alzheimer's disease (AD) patients' longitudinal deterioration in the ability to conduct numerous activities required for daily living. In this study, 52 patients with AD were assessed at baseline and at a 1-year follow-up using the Direct Assessment of Functional Status (DAFS) scale, an objective, well-validated measure of a broad spectrum of functional capacities that is administered within the clinical setting. An important finding was that the level of initial performance on each of the 11 functional tasks measured did not relate to the degree of functional decline in that particular area. Communication skills, such as using the telephone (deterioration among 35.4% of the patients) and preparing a letter for mailing (deterioration among 32.7%), showed the most frequent deterioration among patients upon follow-up. More than half of the AD patients studied demonstrated impairment on one or both of these measures. The pattern of findings indicates that many subtests of the DAFS were sensitive to functional decline after a 1-year period and that the scale has utility in objectively establishing longitudinal patterns of deterioration.

Caregiving for Hispanic Alzheimer's disease patients: understanding the problem.

The authors analyze aspects of caregiving for Hispanic Alzheimer's disease (AD) patients. A review of the literature on caregiving and ethnicity and data concerning caregiving for AD patients in different Hispanic groups are presented. The presence of ethnicity-related differences in caregiving for Hispanic AD patients is confirmed. These differences, however, appear to be present largely in certain areas, such as household composition, distribution of caregiving roles, help-seeking behavior, and site of caregiving. The authors consider areas that need to be addressed in future research and specific modifications to current caregiving models for the study of AD patients in the Hispanic community.

Daughters caregiving for Hispanic and non-Hispanic Alzheimer patients: does ethnicity make a difference?

This study assessed Cuban-American Hispanic and White non-Hispanic daughters who were major caregivers for their mothers suffering from Alzheimer's Disease. Although patients in both ethnic groups did not differ in their level of cognitive and functional impairment, Cuban-American Hispanic patients were significantly more likely to be living in their daughters' homes while the White non-Hispanic patients resided in institutional settings. Caregivers were equivalent in their knowledge and utilization of community services, but Cuban-American daughters were significantly more aware of financial aid resources. Cuban-American patients were significantly more depressed than their White non-Hispanic counterparts with daughters showing similar but nonsignificant trends. The impact of cultural factors on caregiving is discussed.

Attention deficit disorder in children at risk for anxiety and depression.

The comorbidity between attention deficit disorder (ADD) and anxiety and/or depressive disorders was examined in the children of parents with panic disorder, major depressive disorder, or with no diagnosis. A child received a diagnosis by a self-report, parent report, and by consensus, using a best estimate procedure. The prevalence rates of ADD were significantly greater in offspring of parents with depressive and panic disorder by the parents' report and in children of depressed parents by consensus. A significant relationship between ADD and anxiety and/or depression was found for parent, child, and consensus diagnoses. Higher rates of ADD were reported by children (1% versus 13%), parents (8% versus 31%), and in the consensus diagnoses (13% versus 29%) when anxiety and/or depression was present. These results suggest that in children referred for evaluation of ADD, the possibility of a primary anxiety or depressive disorder should be considered.

Coping resources and depression in the caregiving spouses of Alzheimer patients.

This study deals with the self-rated impact of caring for a spouse with Alzheimer's disease at home. Impacts on the caregiver's marriage, work, recreation and mood were investigated as a function of the patient's disability level and of the coping resources which caregivers reported were available to and/or used by them. The patient's disability level had a more negative impact on the caregiver's marriage and recreation than did the coping resource variables whereas the reverse was true for work. The caregiver's work was the only life area in which the availability and mobilization of coping resources influenced the caregiver's level of depression. To clarify these results, additional regression analyses were conducted separately for homemakers and employed subjects. While mobilized coping resources (social activity level and homemaking activity level) were correlated with depression among homemakers, none of the indicators of mobilized coping resources was correlated with depression among workers. These findings suggest that the role in which stress occurs is an important factor in understanding stress and the coping process.

Interpersonal concomitants and antecedents of depression among college students.

Depressed college students were compared with other-psychopathology and normal controls regarding the relationship they developed with dormitory roommates during a 9-month period. Diagnostic status was periodically assessed via SADS interviews, thus also permitting identification of new cases of depression during the year. Psychosocial characteristics found to be uniquely associated with current depression were: (a) low social contact with roommates, (b) low enjoyability of these contacts, and (c) high life-event stress. Roommates of depressives reported low enjoyability of the relationship and high levels of aggressive behavior towards the depressive. No features were found to be uniquely associated with new cases before they became depressed; however, several antecedents of general psychopathology were identified.
