De GDS-8: een korte, cliënt- en gebruikersvriendelijke versie van de Geriatrische Depressie Schaal voor verpleeghuizen

The GDS-8; a short, client- and user-friendly shortened version of the Geriatric Depression Scale for nursing homes The objective of this study was to construct a patient- and user-friendly shortened version of the Geriatric Depression Scale (GDS) that is especially suitable for nursing home patients. The study was carried out on two different data bases including 23 Dutch nursing homes. Data on the GDS (n=410), the Mini Mental State Examination (n=410) and a diagnostic interview (SCAN; n=333), were collected by trained clinicians. Firstly, the items of the GDS-15 were judged on their clinical applicability by three clinical experts. Subsequently, seven items that were identified as unsuitable were removed using the GDS-data of the Assess-project (n=77), and internal consistency was calculated. Secondly, with respect to criterion validity (sensitivity, specificity, area under ROC and positive and negative predictive values), the newly constructed 8-item version of the GDS was validated in the AGED data set (n=333), using DSM-IV diagnosis for depression as measured by the SCAN as ‘gold standard’. In the AGED dataset, the GDS-8 was internally consistent (a=.80) and high sensitivity rates of 96.3% for major depression and 83.0% for minor depression were found, with a specificity rate of 71.7% at a cut-off point of 2/3. The GDS-8 has good psychometric properties. Given that the GDS-8 is less burdening for the patient, more comfortable to use and less time consuming, it may be a more feasible screening test for the frail nursing home population.

Prevalence and diagnosis of depression in frail nursing home patients; a pilot study

The prevalence and recognition of depression among physically frail patients living in an urban Dutch nursing home were estimated. To patients with Mini-Mental-Status-Examination (MMSE) scores of 15 or above, the Geriatric Depression Scale (GDS) was administered (N = 80). With this screen clinically relevant depressive symptoms can be established. For diagnosing major depression according to the DSM-IV criteria, the Diagnostic Interview Schedule (DIS) (N = 57) was administered using a MMSE cut-off of 20. 49% of the respondents showed a score above the GDS cut-off (> 11), which means having clinically relevant depressive symptoms. 16% met the criteria for major depression according to DIS. Nursing home physicians recognized 39% of the patients with clinically relevant depressive symptoms and 67% of those with a major depression. Nurses recognized depressive patients slightly better but they were less specific in their judgement (more false-positive rates). We also found that in situations in which physicians and nurses had the same opinion the recognition of depression improved. Therefore it is recommended that physicians and nurses exchange their judgements on patients' mood on a regular basis.     

Cognitive Impairment,Depression, Comorbidity of the Two and Associated Factors among the Early Sixties in a Rural Korean Community

This study was conducted to investigate the prevalence of cognitive impairment, depression, and comorbidity of the two conditions and related factors in subjects aged in early 60s. This cross-sectional study included 3,174 inhabitants aged 60–64 years old in a rural area of Korea. Cognitive function was evaluated by the Korean version of the Mini-Mental State Examination (MMSE-K), and depression was measured using the short form of the Geriatric Depression Scale (GDS-15). The overall prevalence of cognitive impairment (MMSE-K≤24) was 17.4%, that of depression was 26.0% (GDS-15≥8), and the co-morbidity was 7.1%. Female gender, living with one housemate, and high GDS-15 score were significantly associated with increased cognitive impairment. Employment status and more years of schooling were associated with a decreased probability of cognitive impairment. Increased depression was significantly associated with bereavement and receiving benefits from the Medical Aid Program. Employed status, more years of schooling, and higher MMSE-K scores were significantly associated with decreased depression. The risk of comorbidity was associated with bereavement and receipt of Medical Aid benefits (odds ratio[OR], 1.85; 95% confidence interval[CI], 1.26–2.71; OR, 5.02; 95% CI, 2.37–10.63; respectively). Employment and more years of schooling were associated with a lower risk of comorbidity (OR, 0.46; 95% CI, 0.34–0.62, P-trend <0.01). The correlated factors for cognitive impairment, depression, and comorbidity of the two conditions were similar, and employment status and years of schooling were associated with all three conditions.     

A Depressive Endophenotype of Mild Cognitive Impairment and Alzheimer’s Disease

Background

Alzheimer’s disease (AD) is a devastating public health problem that affects over 5.4 million Americans. Depression increases the risk of Mild Cognitive Impairment (MCI) and AD. By understanding the influence of depression on cognition, the potential exists to identify subgroups of depressed elders at greater risk for cognitive decline and AD. The current study sought to: 1) clinically identify a sub group of geriatric patients who suffer from depression related cognitive impairment; 2) cross validate this depressive endophenotype of MCI/AD in an independent cohort.

Methods and Findings

Data was analyzed from 519 participants of Project FRONTIER. Depression was assessed with the GDS30 and cognition was assessed using the EXIT 25 and RBANS. Five GDS items were used to create the Depressive endophenotype of MCI and AD (DepE). DepE was significantly negatively related to RBANS index scores of Immediate Memory (B=-2.22, SE=.37, p<0.001), visuospatial skills (B=-1.11, SE=0.26, p<0.001), Language (B=-1.03, SE=0.21, p<0.001), Attention (B=-2.56, SE=0.49, p<0.001), and Delayed Memory (B=-1.54, SE = 037, p<0.001), and higher DepE scores were related to poorer executive functioning (EXIT25; B=0.65, SE=0.19, p=0.001). DepE scores significantly increased risk for MCI diagnosis (odds ratio [OR] = 2.04; 95% CI=1.54-2.69). Data from 235 participants in the TARCC (Texas Alzheimer’s Research & Care Consortium) were analyzed for cross-validation of findings in an independent cohort. The DepE was significantly related to poorer scores on all measures, and a significantly predicted of cognitive change over 12- and 24-months.

Conclusion

The current findings suggest that a depressive endophenotype of MCI and AD exists and can be clinically identified using the GDS-30. Higher scores increased risk for MCI and was cross-validated by predicting AD in the TARCC. A key purpose for the search for distinct subgroups of individuals at risk for AD and MCI is to identify novel treatment and preventative opportunities.     

Serum Zinc Concentrations Correlate with Mental and Physical Status of Nursing Home Residents

Introduction

Zinc (Zn) is one of the most important trace elements in the body. Zn deficiency seems to play a role in the development of age-related diseases and impairment of quality of life. Zn status has been especially studied in free-living or hospitalised people, but data from older residents of nursing homes are scarce. This study aimed to determine the Zn status among the older individuals in correlation to their mental and physical performance.

Methods

A total of 100 participants aged between 60-102 years were recruited between October 2010 and May 2012 at the nursing home in Bialystok (Poland). Zn status was evaluated by determining the concentration in serum by flame atomic absorption spectrometry. Anthropometric variables and fitness score (FS) were measured. Abbreviated Mental Test Score (AMTS), Geriatric Depression Scale (GDS), Self-Rated Health (SRH), independence in Activities of Daily Living (ADL) were recorded.

Results and Discussion

The mean serum Zn concentration was 0.83±0.20 mg/L, 28% of residents had Zn deficiency. Cognitive functions were impaired (AMTS≤8) in 45% of the studied persons and 48% showed depressive symptoms (GDS≥1). The ability to independently perform activities of daily living (ADL = 6) was found in 61% of participants, but most of them (90%) had weak body type (FS<70), correlating with GDS, SRH and body mass index (BMI). Serum Zn concentration correlated with mental efficiency and was statistically significantly higher in older people with normal cognitive function and without depression than in patients with memory impairment and showing depressive symptoms.

Conclusions

Nursing home residents seem at risk of marginal Zn status, which correlates with their mental status as measured by the AMTS and GDS. Their low FS is associated with mental health deterioration and obesity.     

Involvement of a small GTP-binding protein (G protein) regulator, small G protein GDP dissociation stimulator, in antiapoptotic cell survival signaling

Small GTP-binding protein GDP dissociation stimulator (Smg GDS) regulates GDP/GTP exchange reaction of Ki-Ras and the Rho and Rap1 family members and inhibits their binding to membranes. In fibroblasts, Smg GDS shows mitogenic and transforming activities in cooperation with Ki-Ras. However, the physiological function of Smg GDS remains unknown. Here we show that mice lacking Smg GDS died of heart failure shortly after birth, not resulting from developmental heart defects but from enhanced apoptosis of cardiomyocytes triggered by cardiovascular overload. Furthermore, neonatal thymocytes and developing neuronal cells underwent apoptotic cell death. Smg GDS-/- thymocytes were susceptible to apoptotic inducers, such as etoposide and UV irradiation. Smg GDS-/- thymocytes were protected from etoposide-induced cell death by ex vivo transduction of the Smg GDS cDNA. These phenotypes partly coincide with those observed in Ki-Ras-deficient mice, suggesting that Smg GDS is involved in antiapoptotic cell survival signaling through Ki-Ras.     

Indicators of early Alzheimer dementia in family practice. Development and validation of the Observation List of Early Symptoms of Dementia (OLD)

Aim of the study was the development and validation of a short observation list of possible early signs of dementia (OLD) for use in general practice. A stepwise development was carried out using reviews of publications and expert consensus. Experimental observations were carried out by 22 general practitioners in 19 Dutch practices. A field study (with interviews and family forms) was conducted out afterwards, to evaluate reliability and validity. Data reduction techniques were used to construct a short version. The first two patients seen on 15 working days (N = 470) were observed. Inclusion criteria: age > 75, without a known diagnosis of dementia. Exclusion: psychiatric treatment, severe depression, acute illness with confusion. The patients were divided into three groups with no, intermediate, and the most signs (total of interviewed patients n = 60; family forms n = 39). Cronbach's alpha and factor-analysis were used to evaluate the reliability. The Cognitive Screening Test (CST), the Word Learning Test (WLT; total and retention), the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), the Groningen Activities Restriction Scale (GARS), and an IADL scale were used to evaluate convergent validity. The Geriatric Depression Scale (GDS) was used to evaluate discriminant validity. Construct validity was evaluated using PRINCALS. Incremental validity was evaluated using the intuitive opinion of the GP (McNemar test). The reliability in the total group was 0.88, the first factor explained 42.5% of the variance. Convergent validity (2-side ANOVA) results: CST (p = 0.00), WLT-total (p = 0.001), WLT retention (p = 0.00), IQCODE (p = 0.09). No statistically significant differences were found for GARS and IADL. The GDS (p = 0.30) showed no difference. The first factor of PRINCALS explained 48% of the variance. The OLD added to the GP opinion (McNemar p = 0.00). Reliability of the short version (12 items) was 0.89 (interviewed group), and 0.86 (total group). The conclusion is that the OLD is a valid and reliable method to detect early signs of dementia in general practice. (Partly adapted from: Hopman-Rock M, Tak ECPM, Staats PGM.

5-Hydroxyindoleacetic acid and homovanillic acid concentrations in cerebrospinal fluid in patients with Alzheimer's disease, depression and mild cognitive impairment

In this study we investigated the cerebrospinal fluid (CSF) concentrations of 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) in Alzheimer (AD) patients (n=75), patients with mild cognitive impairment (MCI, n=9) and patients with depression (n=7). CSF HVA was significantly elevated in AD with depression (Geriatric Depression Scale, 15 point version GDS>5) in comparison to AD without depression (p<0.05, ANOVA) and CSF HVA showed a significant positive correlation with the GDS score of AD-patients (p=0.03, Spearman Rho: 0.38, Spearman Rank Correlation). In the group of AD patients CSF 5-HIAA was positively correlated with cerebrospinal fluid beta-amyloid 1-42 (Abeta42), p<0.05, Spearman Rho: 0.3, Spearman Rank Correlation, but not with CSF tau. Additionally, there was a significant positive correlation between cerebrospinal fluid 5-HIAA and HVA in the group of AD patients (p<0.0001, Rho: 0.47, Spearman Rank correlation). Neither 5-HIAA nor HVA in CSF could differentiate between mild cognitive impairment, depression and AD. The results of this study support the hypothesis that the serotonergic system plays a role in the course of AD. They further suggest an important role of dopamine metabolism in depression within AD patients.     

Depression and subjective quality of life among outpatients with diabetes mellitus at a teaching hospital in Nigeria

Objective To determine the relationship between depression and the subjective assessment of quality of life (QoL) in a sample of patients with diabetes mellitus (DM) attending outpatient clinics at a regional university teaching hospital in Nigeria.Methods A cross-section of 200 patients were administered the depression module of the Schedule for the Clinical Assessment in Neuropsychiatry (SCAN) and the World Health Organization Quality of Life assessment - brief version (WHOQoL-Bref) over a two-month study period.Results A major depressive disorder (MDD) was diagnosed in 30% of patients. MDD was significantly associated with lower mean scores on the facets of overall QoL (p<0.01) and health satisfaction (p<0.01), but not in the domains of physical health (p=0.67), psychological health (p=0.59), environment (p=0.70), or social relations (p=0.58) of the WHOQoL-Bref.Conclusion Depression is associated with a poorer subjective assessment of QoL among DM patients in Nigeria.     

Neuropsychiatric inventory questionnaire (NPI-Q): A validity study of the Dutch form

The Neuropsychiatric Inventory is a clinical instrument for assessing behavioral and psychological symptoms in dementia. It is based on an interview with the primary caregiver. A brief questionnaire form of the NPI was developed, intended for use in routine clinical practice (NPI-Q). This study evaluates the validity of the NPI-Q Dutch form. The NPI-Q was compared to other questionnaires, i.e. the Revised Memory and Behavioural Problems Checklist (RMBPC), the short form Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE-N), the 15 items Geriatric Depression Scale (GDS-15) and the Cognitive Screening Test (CST-20). A data set was used of geriatric outpatients who were referred for neuropsychological assessment (n = 29). Correlations between the NPI-Q and RMBPC Depression- and Disinhibition subscales were relatively high. No relationship was found between the NPI-Q and the RMBPC Memory related behavioral changes subscale, or between the NPI-Q and the IQCODE-N and the CST-20. Informant ratings on the NPI-Q depression-item were related with patient ratings on the GDS-15, especially when patients were relatively mildly cognitive impaired. Caregiver distress was strongly associated with NPI-Q symptom assessment. In conclusion: our preliminary results support validity of the NPI-Q Dutch form. It is a practical rating scale for assessing neuropsychiatric symptoms in dementia and associated caregiver distress.     

Depression Affects the Scores of All Facets of the WHOQOL-BREF and May Mediate the Effects of Physical Disability among Community-Dwelling Older Adults

Background

Geriatric depression is associated with the overall quality of life (QOL). However, how depressive symptoms affect the different domains and facets of QOL in older adults, and whether depressive symptoms mediate the relationship between physical disability and QOL in older adults are unclear.

Methods

A total of 490 ambulatory community-dwelling older adults aged 65 years or above were interviewed using the brief version of the World Health Organisation Quality of Life instrument (WHOQOL-BREF), the Modified Barthel Index (MBI), the 15-item Geriatric Depression Scale (GDS-15), and the Mini-Mental State Examination (MMSE). Sequential models for multiple linear regressions were analysed to determine if the MBI, GDS-15 and MMSE scores predict the WHOQOL-BREF scores. The potential mediation effects of depression (as determined by the GDS-15) on the relationship between MBI and WHOQOL-BREF were also analysed.

Results

The GDS-15 score was predictive of the scores of the four domains and all 26 facets of the WHOQOL-BREF. The significant predictive effects of the MBI score on 15 of the 26 facets of the WHOQOL-BREF were reduced to three after the adjustment for the GDS-15 score. Depression (as assessed by the GDS-15) is a mediator of the relationship between MBI and the physical, psychological and environmental domains of the WHOQOL-BREF.

Conclusions

Depression (assessed by the GDS-15) may affect the scores of every domain and all facets of the WHOQOL-BREF in the elderly. Furthermore, it may mediate the relationship between the MBI and on QOL scores. We recommend taking depressive symptoms into consideration when measuring community-dwelling older adults’ QOL and providing active ageing programs.     

Detecting psychogeriatric problems in primary care: factors related to psychiatric symptoms in older community patients

Objective The aim was to determine the relationship and influence of different variables on the psychiatric symptomatology of older people who reside in the community, as detected by family practitioners.Design A cross-sectional and multi-centre study.Setting Twenty-eight general practices and two psychiatric practices in Huesca, Spain, from 19 primary care health centres.Subjects A sample of 324 patients aged over 65 years, representative of the older people who reside in the community in the province of Huesca.Main outcome measures Symptoms of depression (Yesavage GDS), cognitive impairment (MMSE), anxiety (GADS), psychotic symptoms, obsessive symptoms and hypochondriacal ideas (GMS) were measured by family practitioner and were detected following specific questions from the Geriatric Mental State (GMS-B) examination, following DSM-IV criteria, being defined as 'concern and fear of suffering, or the idea of having a serious disease based on the interpretation of somatic symptoms'. Sociodemographic, physical and somatic, functional and social data were evaluated. Analysis was carried out in three phases: univariate, bivariate and multivariate with logistic regression.Results At the time of the study, 46.1% of the older people studied suffered from some psychiatric symptom; 16.4% had cognitive impairment, 15.7% anxiety, 14.3% depression, 6.1% hallucinations and delusions, 7.2% hypochondriacal ideas and 4.4% obsessive symptoms. Female gender was significantly associated with depression (prevalence ration (PR) 3.3) and anxiety (PR 3.9). Age was a factor associated with cognitive impairment (PR 4.4). Depression was significantly related to severity of the physical illness (PR 61.7 in extremely severe impairment). Isolation (PR 16.3) and being single (PR 13.4) were factors which were strongly associated with anxiety; living in a nursing home was associated with psychotic symptoms (PR 7.6).Conclusions Severity of physical illness, isolation, living in a nursing home and female gender, among others, are related to psychiatric symptoms in community-residing older people identified in primary healthcare centres.     

Een handreiking voor familieleden over palliatieve zorg bij dementie: evaluatie door zorgverleners en familieleden

Families of nursing home residents with dementia are usually involved in care and treatment decisions. To this end, family needs to be informed on the course of the dementia and possible palliative care. Based on a Canadian booklet, we developed an adapted version for use in the Netherlands. Elderly care physicians (n = 30), nurses (n = 38), and bereaved families (n = 59) evaluated the booklet and possible implementation strategies. All respondents confirmed that in general, there is a need of an information brochure on comfort care and end-of-life issues for families. Most (93%) families believed they would have found the booklet useful when received earlier. Compared to the physicians, nurses more frequently found the booklet useful to most or all families (p = 0.04). Acceptance, as measured on an 8-item scale, was highest among families and lowest among physicians. Overall usefulness was often perceived as high (means 7.9 to 8.3; scale range 0-10; SD 0.9 to 1.4) and did not differ across groups of respondents (p = 0.29). All respondents agreed that professional caregivers should have a role in providing the booklet. Additionally, half (53%; no difference across groups) favoured availability of the booklet through families' own initiative; some already before admission. In conclusion, there is a high need for written information on palliative care. The booklet is highly appreciated. A further improved version may support professional and family caregivers in practice.     

The Relationship between Leukocyte Mitochondrial DNA Copy Number and Telomere Length in Community-Dwelling Elderly Women

Purpose

Both telomere length and mitochondrial function are accepted as reflective indices of aging. Recent studies have shown that telomere dysfunction may influence impaired mitochondrial biogenesis and function. However, there has been no study regarding the possible association between telomere and mitochondrial function in humans. Therefore, the purpose of the study was to identify any relationships between mitochondrial and telomere function.

Methods

The present study included 129 community-dwelling, elderly women. The leukocyte mitochondrial DNA copy number and telomere length were measured using a quantitative real-time polymerase chain reaction method. Anthropometric measurement, biochemical blood testing, a depression screening questionnaire using a 15-question geriatric depression scale (GDS-15), and a cognitive function test using the Korean version of the mini mental state examination (K-MMSE) were performed.

Results

Leukocyte mtDNA copy number was positively associated with telomere length (r=0.39, p=<0.0001) and K-MMSE score (r=0.06, p=0.02). Additionally, leukocyte mtDNA copy number was negatively correlated with GDS-15 score (r=-0.17, p=0.04). Age (r=-0.15, p=0.09), waist circumference (r=-0.16, p=0.07), and serum ferritin level (r=-0.13, p=0.07) tended to be inversely correlated with leukocyte mtDNA copy number. With a stepwise multiple regression analysis, telomere length was found to be an independent factor associated with leukocyte mtDNA copy number after adjustment for confounding variables including age, body mass index, waist circumference, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, hs-CRP, serum ferritin, HOMA-IR, K-MMSE, GDS-15, hypertension, diabetes, dyslipidemia, currently smoking, alcohol drinking, and regular exercise.

Conclusions

This study showed that leukocyte mtDNA copy number was positively correlated with leukocyte telomere length in community-dwelling elderly women. Our findings suggest that telomere function may influence mitochondrial function in humans.

Depression,Antidepressant Use and Mortality in Later Life: The Health in Men Study

Context

Depression is associated with increased mortality, but it is unclear if this relationship is dose-dependent and if it can be modified by treatment with antidepressants.

Objective

To determine if (1) the association between depression and mortality is independent of other common potential causes of death in later life, (2) there is a dose-response relationship between increasing severity of depression and mortality rates, and (3) the use of antidepressant drugs reduces mortality rates.

Methods

Cohort study of 5,276 community-dwelling men aged 68–88 years living in Perth, Australia. We used the Geriatric Depression Scale 15-items (GDS-15) to ascertain the presence and severity of depression. GDS-15≥7 indicates the presence of clinically significant depression. Men were also grouped according to the severity of symptoms: “no symptoms” (GDS-15 = 0), “questionable” (1≤GDS-15≤4), “mild to moderate” (5≤GDS-15≤9), and “severe” (GDS-15≥10). Participants listed all medications used regularly. We used the Western Australian Data Linkage System to monitor mortality.

Results

There were 883 deaths between the study assessment and the 30th June 2008 (mean follow-up of participants: 6.0±1.1 years). The adjusted mortality hazard (MH) of men with clinically significant depression was 1.98 (95%CI = 1.61–2.43), and increased with the severity of symptoms: 1.39 (95%CI = 1.13–1.71) for questionable, 2.71 (95%CI = 2.13–3.46) for mild/moderate, and 3.32 (95%CI: 2.31–4.78) for severe depression. The use of antidepressants increased MH (HR = 1.31, 95%CI = 1.02–1.68). Compared with men who were not depressed and were not taking antidepressants, MH increased from 1.22 (95%CI = 0.91–1.63) for men with no depression who were using antidepressants to 1.85 (95%CI = 1.47–2.32) for participants who were depressed but were not using antidepressants, and 2.97 (95%CI = 1.94–4.54) for those who were depressed and were using antidepressants. All analyses were adjusted for age, educational attainment, migrant status, physical activity, smoking and alcohol use and the Charlson comorbidity index.

Conclusions

The mortality associated with depression increases with the severity of depressive symptoms and is largely independent of comorbid conditions. The use of antidepressants does not reduce the mortality rates of older men with persistent symptoms of depression.     

Relationships between depression,lifestyle and quality of life in the community dwelling elderly: a comparison between gender and age groups

This study aimed to comprehensively investigate the comprehensive relationships between depression and the characteristics of lifestyle and quality of life (QOL) of healthy, community dwelling elderly, and compare them according to gender and age groups. 1302 subjects (657 males and 645 females) were used for analysis. The investigators in this study were researchers working at universities in each prefecture. Data collection was conducted in a general delivery survey and interview setting or an education class setting. The geriatric depression scale (GDS) consisting of 15 items with a dichotomous scale was used to assess depression symptoms in the elderly. In addition, 16 items selected from the four factors of economic situation, physical health, social activity, and personal status were used to assess lifestyle. Furthermore, this study investigated life satisfaction, morale, and physical function with the LSI scale, PGC morale scale and the ADL scale of the Ministry of Education, Science and Culture, respectively. According to our results, depression characteristics of the elderly differ between gender and age groups. Depression increases in the old-old elderly rather than in the young-old elderly and is highest in old-old females. The factors significantly related to depression in community dwelling elderly were the number of friends and morale. In particular, an increase in the number of friends was related to a decrease in depression. Depression in the old-old elderly was more significantly related to many lifestyle items compared with the young-old elderly, and especially in the old-old elderly, the extent of social activities related to a decrease in depression.     

Evaluación breve del estado cognitivo de la demencia en estadios avanzados: resultados preliminares de la validación española del Severe Mini-Mental State Examination

Introduction

The cognitive assessment of patients with advanced dementia needs proper screening instruments that allow obtain information about the cognitive state and resources that these individuals still have. The present work conducts a Spanish validation study of the Severe Mini Mental State Examination (SMMSE).

Material and methods

Forty-seven patients with advanced dementia (Mini-Cognitive Examination [MEC]<11) were evaluated with the Reisberg's Global Deterioration Scale, MEC, SMMSE and Severe Cognitive Impairment Profile scales.

Results

All test items were discriminative. The test showed high internal ( α = 0.88), test-retest (0.64 to 1.00, P < .01) and between observers reliabilities (0.69-1.00, p < 0.01), both for scores total and for each item separately. Construct validity was tested through correlations between the instrument and MEC scores (r = 0.59, P < 0.01). Further information on the construct validity was obtained by dividing the sample into groups that scored above or below 5 points in the MEC and recalculating their correlations with SMMSE. The correlation between the scores in the SMMSE and MEC was significant in the MEC 0-5 group (r = 0.55, P < .05), but not in the MEC>5 group. Additionally, differences in scores were found in the SMMSE, but not in the MEC, between the three GDS groups (5, 6 and 7) (H = 11.1, P < .05).

Conclusions

The SMMSE is an instrument for the assessment of advanced cognitive impairment which prevents the floor effect through an extension of lower measurement range relative to that of the MEC.From our results, this rapid screening tool and easy to administer, can be considered valid and reliable.     

Prevalencia de síntomas neuropsiquiátricos en pacientes institucionalizados con diagnóstico de demencia y factores asociados: estudio transversal multicéntrico

Objective

The aim was to estimate the prevalence and severity of neuropsychiatric symptoms in patients with dementia in nursing homes, assessing their association with certain factors that may influence their occurrence.

Material and methods

A cross-sectional study was carried out, and included all elderly patients diagnosed with degenerative, vascular, or mixed dementia, stage 4 to 7 on the Global Deterioration Scale of Reisberg (GDS), and residents in 6 nursing homes in the province of Ourense (Spain). A sample size of 120 individuals was determined to be necessary. The assessment of symptoms was performed using the Neuropsychiatric Inventory-Nursing Home test. The influence of the determined factors was investigated using logistic and linear regression analysis, and subsequently corrected for possible confounding factors.

Results

A total of 212 cases were included, with a mean age of 85.7 (SD = 6.7) years. The prevalence of neuropsychiatric symptoms was 84.4%. The most common symptom was apathy, followed by agitation and delirium, and the least frequent were euphoria and hallucinations. The symptom that produced most occupational disruption was agitation. Multivariate analysis showed that a higher score on the NPI-NH was associated with a higher score on the Global Deterioration Scale of Reisberg, the use of neuroleptics, cholinesterase inhibitors, and memantine.

Conclusions

In nursing home patients, prevalence of neuropsychiatric symptoms was high, and associated with the severity of dementia (GDS), the use of neuroleptics, cholinesterase inhibitors, and memantine.
