The paper shows the results on the relationship between zinc status, psychological dimensions (cognitive functions, mood, perceived stress) and nutritional aspects in European healthy old subjects recruited for ZINCAGE Project (supported by the European Commission in the Sixth Framework Programme). The old healthy subjects were recruited in Italy, Greece, Germany, France, Poland taking into account the different dietary habits between Northern and Southern European Countries and the pivotal role played by zinc for psychological functions. Measures of the cognitive status, mood and perceived stress level were obtained at baseline, using the "Mini Mental State Examination (MMSE)"; the "Geriatric Depression Scale (GDS - 15 items)" and the "Perceived Stress Scale (PSS)", respectively. Nutritional status was assessed using "Frequency Food Questionnaire". The sample included 853 old subjects, classified in 4 groups of age: 60-69-years-old (n = 359); 70-74-years-old (n = 225); 75-79-years-old (n = 153); 80-84-years-old (n = 116). Subjects were studied on the basis of plasma zinc, in which zinc </=11 microM means marginal zinc deficiency. The total samples showed that the 82% had no cognitive decline, whereas 76% presented a low GDS value indicating no depression. However, all psychological variables were related to plasma zinc values and nutritional assessment. In particular, a relationship between marginal zinc deficiency and impaired psychological dimensions occurred in Greece than in other European countries due to low intake and less variety of foods rich of zinc. This phenomenon was independent by the age, suggesting that a correct zinc intake from a wide range of foods may be useful to maintain a satisfactory plasma zinc levels as well as psychological status in elderly with subsequent achievement of healthy ageing.

The role of thyroid function in Alzheimer's disease (AD) has been subject to a number of studies during the last years. We investigated the possible relationship between plasma levels of the biologically active free form of thyroxin (fT4) and cognitive function in 227 outpatients with mild to moderate Alzheimer s disease (AD) in a cross-sectional study design. A significant negative correlation was found between plasma fT4-levels and Mini-Mental state examination (MMSE) score (Spearman Rho = -0.14, p=0.04). When the lowest quartile of fT4-levels (<15.1 pmol/l) was compared to the highest quartile (>19.0 pmol/l), statistically significant lower mean MMSE-scores were seen in the group with the highest fT4-levels (p<0.05, ANOVA). The mean difference between the 1st and the 4th quartile of fT4 was 2.6 MMSE-score points. No correlations were found between plasma total T4-levels, plasma total T3-levels, plasma TSH-levels and the MMSE score (p>0.05). When fT4 quartile groups were compared for depression measured in the Geriatric Depression Score (GDS 15), a slightly higher score was seen in the 1s and 2nd compared to the 3rd and 4th quartile groups without reaching statistical significance (1st quartile of fT4: GDS 5.2 +/- 3.8; 2nd: 5.3 +/- 4.0; 3rd: 4.4 +/- 3.4; 4th: 4.5 +/- 3.8) pointing to a reverse correlation of fT4 levels and depressive mood. This study leads to the conclusion that high levels of plasma fT4 might result in a worsening of cognitive impairment and a positive effect on depressive mood in AD.

Religiosity is an important aspect of the life of older people, particularly in the Arab region where religiosity is an important part of daily social and political life. Studies have documented the relationship between religiosity and depression among older people, but none in the region. A total of 740 persons aged 60 + were interviewed in three poor urban areas of Lebanon, one of which was a Palestinian refugee camp. The questionnaire included five items on religiosity covering organizational and intrinsic religiosity. Depression was assessed using the 15-item Geriatric Depression Score (GDS-15). Depression was prevalent in 24% of the older persons interviewed with the highest proportion being from the Palestinian refugee camp (31%). Results suggest that only organizational religiosity was related to depression and this pattern was only significant among the refugee population. Religious practice is discussed as an indicator of social solidarity rather than an aspect of religiosity. Minority groups may rely on religious stratagems to cope with their distress more than other groups.

The study of the interactions among biological factors and psychosocial conditions is a very innovative field, because data are lacking in the scientific literature. Among biological aspects, zinc is an essential element in the elderly, especially in relation to one of the proteins, such as albumin, involved in zinc transport into the cells. In this study, the aim is the assessment of the interrelationship between albumin value (used as an index of the body zinc status) and some psychosocial dimensions in elderly Italian sample recruited for ZINCAGE project, supported by the European Commission in the "Sixth Framework Programme". Some tests and questionnaires were administered to older people included in the trial: the "life-style questionnaire"; the mini mental state examination (MMSE); the geriatric depression scale (GDS-15 items). On the basis of the Senieur Protocol for gerontological studies, a sample of 291 Italian healthy old subjects has been recruited in Central Italy and divided into 3 age groups: (a) 125 subjects aged from 65 to 74 years, (b) 89 subjects aged from 75 to 84 years, (c) 77 subjects aged >or=85 years (classified like successful old people). No cognitive impairment assessed by MMSE was observed in 67.5% of the sample; 64.0% had GDS score less than 5, indicating no depression, whereas the prevalence of biological albumin deficiency (<3.5 g/dl) found in Italian old people was 21.0%. Sixty one percent of subjects with albumin deficiency displayed higher values of GDS (>or=5). These preliminary results showed an interrelationship among serum albumin value and psychosocial aspects in Italian old population, suggesting that low albumin values may be involved in impaired psychological dimensions.

Dementias, in particular Alzheimer's disease (AD), are the main reason for availing of nursing home care. In the course of the illness, the clinical picture is affected by cognitive decline and by other psychopathological, "non-cognitive" symptoms such as apathy, depression, delusions or agitation. Little attention has been paid to these symptoms, although they lead to an increase in strain on the patients and their relatives as well as complications in nursing care. Psychopathological symptoms were evaluated by using the Neuropsychiatric Inventory in 145 nursing home residents (age: 85 +/- 7 years, duration of stay: 35 +/- 48 months); the majority of them with moderate to severe dementia (GDS: 5 +/- 2; MMSE: 11 +/- 9). In addition, the Apathy Evaluation Scale was applied. To meet potential regional effects, residents were recruited in nursing homes in the areas around Heidelberg as well as Munster. 87% of the participants showed psychopathological symptoms of an at least moderate degree, depressive mood (52%), apathy (41%) and agitation (38%) being most frequent. General condition, nutritional status and care status were evaluated as 'good', likewise general health care. In contrast, only 27% were treated by psychiatrists. 70% received psychopharmacological treatment, mostly sedatives (44%), while antidementive drugs were used only in 11%. The findings underline the need of further information and advanced training.

The purpose of this study was to compare the validity of the 15-item Geriatric Depression Scale (GDS-15) in nonelderly (<65 years), young-elderly (age, 65-75), and old-elderly (>75 years) patients with Parkinson's disease (PD). 57 nonelderly, 88 young-elderly, and 81 old-elderly PD patients were administered the GDS-15 and the Structured Clinical Interview for DSM-IV depression module. Receiver-operating characteristic (ROC) curves were plotted for GDS-15 scores against a DSM-IV diagnosis of major or minor depression. The discriminant validity of the GDS-15 was high for nonelderly, young-elderly, and old-elderly subjects (ROC area under curve = 0.92, 0.91, and 0.95, respectively), with optimal dichotomization at a cut-off of 4/5 (85% sensitivity and 84% specificity in nonelderly; 89% sensitivity and 82% specificity in young-elderly) and 5/6 (90% sensitivity and 90% specificity in old-elderly). In conclusion, the GDS-15 has comparable validity in younger and older PD patients, suggesting its appropriateness as a depression screening instrument in PD patients of all ages.

We have made a questionnaire survey on an enuresis rate among old males living in Vilnus. Using questionnaires on enuresis, MMSE-30 test and GDS-15, we have examined a random sample of 294 males aged 75 to 95 years and older from January 2003 to December 2004. Enuresis was diagnosed in 26.5% of them. In age groups 75-79, 80-84, 85-89, 90-94, 95 years and older enuresis symptoms occurred in 32.8, 24.0, 12.2, 36.4, 9.1% males, respectively. Only 58.4% males with enuresis sought medical advice. Most of the patients suffered from enuresis for 1 to 5 years. The type of incontinence was stated according to international criteria of ICS (2002). The incontinence was urgent in 66.2% and stress in 3.9%. Only 13.0% males used hygienic protectors. The following risk factors were revealed: intake of alpha-adrenoblockers (OR = 3.89, 95% CI = 1.98-7.67), depression (OR = 2.51, 95% CI = 1.13-5.55). The risk to develop continuous incontinence grows in the presence of Parkinson's disease (OR = 3.50; 95% CI = 1.01-12.23), prostatic adenoma (OR = 5.29; 95% CL = 2.91-9.65). The responders believe that their incontinence is due to combination of factors: 2-3 factors were pointed by 36.4%, 4-5 factors--20.8%, 6 and more--by 22.0%.

Depression is one of the most common affective illnesses. The investigation of changeable factors that are associated with depression is an important condition for the establishment of preventive measures. In a cross-sectional study, data on social factors were recorded from 580 geriatric patients of the municipal hospital in Munich. Ordinal logistic regression was used to analyse their association with depression (clinical diagnoses by ICD-10) and depressive symptoms (GDS). The results indicate that the occurrence of depressive symptoms and of depression was associated with less social contacts and less support, even after adjustment for other risk factors (for example, physical and cognitive impairment). This association was more distinct for women (for example, depressive symptoms: moderate versus much contact: OR=2.7; 95% CI: 1.8-4.1) than for men (OR=1.3; 95% CI: 0.7-2.4). Further research is needed to investigate whether women could benefit more than men from programmes promoting social support.

The purpose of this article is to compare the advantages and limitations of developed depression assessment tools and provide recommendations for clinical staff to select an appropriate tool for use with Chinese older adults. A total of 7 Western tools translated into Chinese and 4 tools developed specifically for assessing Chinese older adults were found in 12 articles. Variability in instrument psychometric properties and cutoff scores is discussed. A reasonable strategy to efficiently assess depression in Chinese older adults is to first administer the Single Question or Geriatric Depression Scale-4 (GDS-4). If depression is likely, the Chinese GDS-15 could be used to increase the probability of identifying depression in Chinese older adults.

This study investigated the prevalence of depression by area and socio-economic status (SES). Study participants were 32,891 Japanese elderly aged 65 and over who responded to a postal survey conducted in 15 municipalities in 2003. Depression was assessed using a short version of the Geriatric Depression Scale (GDS-15). SES was measured using years of education and income adjusted for family size. After adjustment for age, illness, higher level of activities of daily living, sex, marital status, and self-rated health, depression was still significantly associated with lower SES and residential area. Further research should also examine the area effect on health.
