Whether called psychogeriatrics, old-age psychiatry, geriatric psychiatry, geriatric psychology, or mental health of the elderly, the clinical disciplines focusing on the mental health problems of older individuals are increasingly becoming recognized as subspecialties of their parent disciplines. Although the rate at which this is occurring is variable, interest is spreading worldwide and will continue to grow.

Recent studies have identified cognitive deficits in semantic memory and verbal language abilities among women with Alzheimer's disease (AD). Few studies to date have explored gender differences in episodic memory function in AD. The present study compared the performance of men and women diagnosed with AD on a battery of neuropsychological measures. Results indicated the presence of gender-related cognitive deficits on tasks of confrontation naming, expressive world knowledge, and both episodic and semantic memory for women with AD, relative to findings in men.

The present study examined the prevalence of dementia in the Nagasaki Prefecture. The purposes of our investigation were (a) to study the relationship between aging and the prevalence of dementia and the ratio of Alzheimer's disease (AD) to vascular dementia (VD), (b) to understand the features of early-onset dementia as seen in patients from 60 to 65 years, and (c) to examine the recognition of dementia by family members. The subjects of the study, a total of 4,368, were all 60 years old and over and were residing in the three areas of Nagasaki Prefecture at the time of the investigation, August 1995. We adopted a two-stage design. The first-stage questionnaire that we developed was delivered to subjects, and we selected for the second stage those subjects who met the criteria outlined in the Methods section. The second-stage investigation was an interview by community nurses and psychiatrists. The prevalence of dementia in subjects 60 years and over was 6.2% (men: 5.9%; women:6.8%). The prevalence increased with age. The AD/VD ratio was 1.4, and was similar to the recent trend in Japan in that the ratio has reversed to resemble the western pattern. In regard to the family members' recognition of illness, the higher the severity of dementia, the higher the recognition ratio of family members became. Only half of these subjects were recognized as having dementia by their family members. In conclusion, the westernization of the AD/VD ratio in Japan was proved. There was little study about family recognition of dementia. In this study, it was remarkable that only half of the subjects were recognized as having dementia by their family members.

This study examines the psychometric properties of two new abbreviated versions of standard measures of depression, a revised eight-item Center for Epidemiological Studies--Depression Scale (CES-D) and a short-form Composite International Diagnostic Interview (short-form CIDI). A sample of 6,133 elders, age 70 years or older, completed both measures as part of the Asset and Health Dynamics Study of the Oldest Old. The revised CES-D had an internal consistency and factor structure comparable to that of prior versions of the CES-D. The sources of discordance between the two measures were examined and the two measures were compared on self-report of four clinical variables: medical illness, physician diagnosis, psychiatric treatment, and antidepressant or tranquilizer use. Both measures were associated with self-report of physician diagnosis and psychiatric treatment. Respondents positive for depression on the CES-D reported higher rates of antidepressant use. Respondents positive on the short-form CIDI only did not report more antidepressant use than nondepressed respondents.

Caregiver support is an important factor in recovery from depression among older patients. We examined whether caregivers' perceptions regarding patients' ability to control depressive symptoms were related to depression recovery. Depression treatment, demographics, number of depressive symptoms, and health were controlled. The sample comprised 51 geriatric psychiatry inpatients who met DSM-IV criteria for major depression and who had a primary caregiver. Depression was assessed at both admission and discharge. Caregivers were asked to indicate whether they believed their patient-relatives could control their depressive symptoms. At discharge, 33 patients (64.7%) were “remitted” and 18 (35.3%) were “nonremitted.” Multivariate analyses indicated that receiving electroconvulsive treatment, having fewer depressive symptoms caregivers perceived to be within patient control, and being female predicted depression remission at discharge. This study highlights the important relationship between family dynamics and course of depression.

The reliability and validity of the Subjective Burden Scale (SBS) were investigated in 255 Japanese family caregivers of elderly relatives with dementia. Values of the Cronbach's alpha reliability, split-half reliability (r), and test-retest reliability (r) were .87, .80, and .72, respectively. The SBS score was significantly positively correlated with the degree of mental health, which was assessed with the Japanese version of the 60-item General Health Questionnaire (r = .41). The family caregivers who gave up the caregiving of their relatives showed significantly higher SBS scores than those who did not. The SBS scores for caregivers indicated satisfactory predictive validity both in the degree of their mental health and in the prospects of family caregiving about 6 months later. These findings suggest that the SBS is adequately reliable and valid and can be used to assess the subjective burden of Japanese caregivers.

Most of the tests, questionnaires, and neuropsychological batteries for the assessment of dementia have been translated and adapted for use in the Hispanic population without having normative data, which results in a high number of false positives when age and educational level are not considered. The Short Cognitive Performance Test (SKT) is a psychometric instrument evaluating memory and attention deficits that has been developed and standardized in Germany (Erzigkeit, 1989a, 1989b). The objective of this study was to adapt the SKT, to establish normative criteria that take into consideration age and educational level, and to establish its concurrent validity in comparison to other neuropsychological tests: Brief Neuropsychological Evaluation for Spanish-Speaking Subjects (Ostrosky-Solís et al., 1994), the Mini-Mental State Examination (Folstein et al., 1975), and the Blessed Functional Scale (Blessed et al., 1968) in 238 neurologically intact subjects and 97 subjects with mild to moderate dementia. The SKT showed adequate sensitivity (80.5%) and specificity (80.3%) in subjects with medium and high educational level; however, the sensitivity and specificity diminished (75% and 56.7%) in subjects with no education or low educational level. The adapted and validated version of the SKT in the Mexican population has been shown to be a psychometric instrument that in subjects with medium educational level can detect cognitive alterations and is able to determine the severity of deterioration; however, in subjects with low educational level and severe dementia, the SKT cannot be usefully administered.

The Revised Memory and Behavior Problems Checklist (RMBPC) is a 24-item caregiver report that measures observable behavioral and memory problems in dementia patients and their caregivers' reaction to these problems. The purpose of the present study was to evaluate the applicability of the RMBPC for use in Taiwanese patients with Alzheimer's disease (AD). The subjects included 76 AD patients (39 men and 37 women, mean age 72.3) and their caregivers (34 men and 42 women, mean age 53.5) who participated in a comprehensive assessment at the Veterans General Hospital-Taipei. The Chinese version of the Cognitive Abilities Screening Instrument was administered to the patients. Their caregivers rated the RMBPC and the short version of the Geriatric Depression Score (GDS). To assess the test-retest reliability, 30 caregivers rated a second RMBPC 3 days after the first evaluation. The mean score for the frequency rating on the RMBPC was 32.63 (SD = 12.44, range = 5–61) and the mean reaction score was 10.96 (SD = 11.53). The reaction score was significantly correlated with the GDS score (r = .363, p = .001). The Cronbach's alpha coefficients for frequency and reaction scores were .816 and .895 respectively. The test-retest reliabilities of total frequency and reaction scores were significantly correlated; overall correlations were .89 for frequency (p < .001) and .74 for reaction (p < .001). These findings suggest that the RMBPC be recommended as a reliable tool to assess behavioral and memory disturbance in Taiwanese AD patients.

Although estimates as to the incidence of personality disorder in the elderly remain controversial, it is well known that such a disorder is prevalently ego-syntonic and capable of interfering with the onset and treatment of other somatic and psychic pathologies, especially in later life, when individuals tend to be particularly vulnerable. Misdiagnosis or failure to treat these disorders may greatly diminish the quality of life of older adults and their families. The aim of this work is to define the chief psychopharmacological and psychotherapeutic guidelines for treating personality disorders in the elderly. Pharmacologically, patients require treatment with molecules designed to rebalance neurotransmitter system alterations, which underlie the symptomatological picture. As regards psychotherapeutic treatment, although there are only a few validation studies, we believe that dialectical behavior therapy and interpersonal psychotherapy may constitute valid therapeutic approaches that meet both the needs and the individual characteristics of patients affected by personality disorder and those of elderly patients.
