Prevalence and predictors of depressive symptoms in a nursing home

The aim of the study was to identify the prevalence of depressive symptoms (GDS score) and predictors of mood changes over a 12-month period in 56 nursing home residents (13 males and 43 females; mean age 81.1 ± 8.6). At baseline, 48.2% of the residents who scores above 11 on the MMSE had a GDS score > 15. GDS score was associated with pain, disabling diseases and self-evaluation of health, and independently with dissatisfaction with the nursing home environment, low level of nursing home social activities and younger age. Five depressed residents became non-depressed, eight non-depressed became depressed and 14 residents remained persistently depressed 12 months after baseline. After controlling for potential confounders, increasing GDS score was independently associated with decreasing basic activities of daily living, increasing number of clinical problems and younger age. Our data support the hypothesis that specific emotional adjustments can be found even in the apparently static environment of the nursing home.     

Prevalence of neuropsychiatric symptoms in a large sample of Dutch nursing home patients with dementia

OBJECTIVE: To estimate the prevalence of neuropsychiatric symptoms of dementia patients in Dutch nursing homes. METHODS: Cross-sectional study in a large sample of 1322 demented patients living in 59 dementia special care units (SCUs) in The Netherlands. Symptoms were observed by licensed vocational nurses during regular care-giving in a 2-week observational period prior to assessment. Neuropsychiatric symptoms were assessed using the Neuropsychiatric Inventory- Nursing home version (NPI-NH; frequency X severity score >/= 4) and the Cohen-Mansfield Agitation Inventory (CMAI; symptoms occurring at least once a week). RESULTS: More than 80% of these patients suffered from at least one clinically significant symptom, as defined with the NPI-NH frequency X severity score >/= 4. Measured with the NPH-NH agitation/aggression, apathy and irritability were the most frequently observed behaviors, with prevalences of 30-35%. Using the CMAI, 85% of the patients showed at least one symptom of agitation, of which general restlessness was observed most frequently (44%). Other frequently observed symptoms with prevalence rates of 30% were cursing or verbal aggression, constant request for attention, negativism, repetitious sentences, mannerisms, pacing, and complaining. Physically aggressive symptoms such as hitting, kicking, biting occurred less often (less than 13%). CONCLUSIONS: Prevalence rates of neuropsychiatric symptoms in Dutch nursing home patients with dementia residing in SCUs are high, especially agitation and apathy. Insight into the prevalence rates of individual symptoms in patients with dementia has important practical consequences for the accurate planning of staff allotment and stresses the need for patient oriented care.     

Prevalence of depressive symptoms and depression in elderly Finnish home nursing patients and home help clients

Depressive symptoms in a population (N = 419) aged 65 years or over and receiving home nursing, home help or both were assessed by postal questionnaires including the Zung self-rating depression scale (SDS). Eighty-six percent participated, and 38 percent of both men and women scored 45 raw sumpoints or more in the SDS. The mean of the raw sumpoints was 42.1 (+/- 9.6) for men (N = 100) and 41.4 (+/- 9.0) for women (N = 238, the difference being nonsignificant. Home help clients scored less than home nursing patients or patients receiving both home nursing and home help. The population scoring 45 raw SDS sumpoints or more was investigated by a general practitioner, and the diagnosis of depression was made according to DSM III-criteria. The clinical investigations showed 26 percent of both men and women who participated to be depressive. Chronic depression was the most common class, followed by atypical depression. About two thirds of the depressive men and half of the depressive women were 'new' cases in that it had not been realized earlier that they suffer from depression. Atypical depression was the class where underdiagnozing was most evident. Among elderly men psychomotor retardation, libido loss, anorexia and indecisiveness and among elderly women psychomotor retardation, indecisiveness, emptiness and diurnal variation were common symptoms of depression.     

Depressive symptoms among cognitively normal versus cognitively impaired elderly subjects

OBJECTIVES: The present cross-sectional study analyzed the prevalence and severity of depressive symptoms among patients with Alzheimer's disease (DAT), vascular dementia (VAD), and among the cognitively normal elderly. Putative risk factors contributing to depression were likewise evaluated. METHODS: Seventy-six DAT patients, 51 VAD patients, and 121 cognitively normal subjects were admitted to the study. Questionnaires concerning demography and their vascular and familial risk factors together with results of neuropsychological testing by combined Mini-Mental Status Examinations (MMSE), Cognitive Capacity Screening Examinations (CCSE), and Hamilton Depression Rating Scales (HDRS) were obtained so that resulting data would be statistically analyzed. RESULTS: Prevalence of depressive symptoms among VAD, DAT, and cognitively normal elderly were 31.4%, 19.9%, and 13.2%, respectively. 25.5% of VAD and 13.2% of DAT patients had depression of mild to moderate degrees. Regression analysis revealed that diagnosis of VAD and DAT, heart disease, and past history of depression was significantly associated with high HDRS scores. There was no correlation between degree of depression and severity of cognitive impairments. CONCLUSION: Mild to moderate depression is a common comorbidity with organic dementia, especially VAD, but associated depression is independent of severity of cognitive impairments.     

Thriving in relation to cognitive impairment and neuropsychiatric symptoms in Swedish nursing home residents

Objectives

The purpose of this study was to explore relations among thriving, cognitive function, and neuropsychiatric symptoms (NPS) in nursing home residents.

Methods

A national, cross‐sectional, randomized study of Swedish nursing home residents (N = 4831) was conducted between November 2013 and September 2014. Activities of daily life functioning, cognitive functioning, NPS, and thriving were assessed with the Katz activities of daily living, Gottfries' Cognitive Scale, Nursing Home version of the Neuropsychiatric Inventory, and Thriving of Older People Scale, respectively. Individual NPS were explored in relation to cognitive function. Simple linear and multiple regression models were used to explore thriving in relation to resident characteristics.

Results

Aggression and depressive symptoms were identified as negatively associated with thriving regardless of resident cognitive functioning. At higher levels of cognitive functioning, several factors showed associations with thriving; however, at lower levels of cognitive functioning, only the degree of cognitive impairment and the NPS was associated with thriving. Most of the individual NPS formed nonlinear relationships with cognitive functioning with higher symptom scores in the middle stages of cognitive functioning. Exceptions were elation/euphoria and apathy, which increased linearly with severity of cognitive impairment.

Conclusions

The lower the cognitive functioning was, the fewer factors were associated with thriving. Aggression and depressive symptoms may indicate lower levels of thriving; thus, targeting these symptoms should be a priority in nursing homes. Copyright © 2017 John Wiley & Sons, Ltd.     

Differences in neuropsychiatric symptoms between nursing home residents with young-onset dementia and late-onset dementia

Objective: The aims of the current study are (1) to explore the differences in neuropsychiatric symptoms (NPS) between young-onset dementia (YOD) and late-onset dementia (LOD), and (2) to investigate whether the possible differences can be attributed to differences in dementia subtype, gender, psychotropic drug use (PDU), or dementia severity.

Method: Three hundred and eighty-six nursing home (NH) residents with YOD and 350 with LOD were included. Multilevel modeling was used to compare NPS between the groups . Furthermore, dementia subtype, gender, PDU, and dementia severity were added to the crude multilevel models to investigate whether the possible differences in NPS could be attributed to these characteristics.

Results: Higher levels of apathy were found in NH residents with YOD. After the characteristics were added to the models, also lower levels of verbally agitated behaviors were found in YOD .

Conclusion: We recommend that special attention be paid to interventions targeting apathy in YOD. Although no differences in other NPS were found, the PDU rates were higher in YOD, suggesting that the threshold for the use of PDU in the management of NPS is lower. This underscores the need for appropriate attention to non-pharmacological interventions for the management of NPS in YOD.     

Neuropsychiatric symptoms in nursing home patients: factor structure invariance of the Dutch nursing home version of the neuropsychiatric inventory in different stages of dementia

BACKGROUND/AIMS: To examine the influence of dementia stage and psychoactive medication use on the factor structure of the Neuropsychiatric Inventory-Nursing Home version (NPI-NH) in Dutch nursing home patients. METHODS: The NPI-NH was administered to a large sample of 1,437 patients with mild to severe dementia receiving nursing home care. Exploratory factor analysis was used to examine behavioural dimensions underlying neuropsychiatric symptoms indicated by the NPI-NH across dementia stages (as assessed with the Global Deterioration Scale - GDS) and in patients with or without psychoactive medication prescribed. RESULTS: In GDS stages 4/5, 6 and 7, a 4- or 5-factor solution was found, with factors referred to as agitation/aggression, depression, psychosis, psychomotor agitation and apathy. These symptom clusters were replicated in the group of drug-naive patients, but only partially in the group of patients on psychoactive medication. CONCLUSION: The factor structure of the NPI-NH in nursing home patients is consistent with the clinical taxonomy of symptoms, is relatively stable across dementia stages, and is only moderately influenced by psychoactive medication use. The division of depression and apathy into separate behavioural dimensions - also in patients with severe dementia - may have important therapeutic consequences.     

Prevalence and clinical correlates of neuropsychiatric symptoms in dementia

The purpose of this research was to assess the frequency and severity of neuropsychiatric and behavioral symptoms and to examine the association between preexisting medical conditions and specific neuropsychiatric symptoms in demented individuals. We studied 211 demented subjects (87.7 percent male) who were participants in epidemiological studies of dementia. Using the Neuropsychiatric Inventory (NPI), we assessed the frequency and severity of neuropsychiatric symptoms. We collected medical history information during a structured telephone interview. Our analyses focused on determining prevalence of neuropsychiatric symptoms by dementia diagnosis and severity. We also examined the association of history of head injury, alcohol abuse, and stroke with development of neuropsychiatric symptoms. We found that neuropsychiatric symptoms were common, with approximately three-fourths of the subjects exhibiting at least one symptom during the preceding month. Apathy (39.3 percent), agitation (31.8 percent), and aberrant motor behavior (31.1 percent) were the most frequent symptoms. Frequency and severity of symptoms were similar for the all-dementia and Alzheimer's disease-only groups, neuropsychiatric symptoms varied by severity of dementia, but generally not in a consistent ordinal pattern. History of alcohol abuse, head injury, or stroke was associated with presence of specific neuropsychiatric symptoms in dementia. While psychiatric symptoms are common in dementia, they also vary by type and severity of dementia. The finding that certain medical conditions may increase risk for specific types of neuropsychiatric symptoms expands our knowledge of the natural history of dementia and should improve management of dementia in medically ill patients. Our results may also shed light on mechanisms that underlie neuropsychiatric symptoms.     

Adverse drug events in cognitively impaired elderly patients

BACKGROUND/AIMS: Adverse drug events (ADEs) are a frequent problem encountered in the elderly. The aim of this study was to elucidate the factors that influence ADEs in an elderly population with cognitive impairment. METHODS: 242 patients were recruited from dementia clinics and assessed after 6 months for ADEs. The use of natural health products (NHPs) was also documented. RESULTS: Backward logistic regression found that higher age (OR = 1.06; 95% CI 1.01-1.12), and greater cognitive impairment (OR = 0.94; 95% CI 0.90-0.98) were associated with an increased risk of developing an ADE while the use of NHPs (OR = 0.32; 95% CI 0.13-0.79) was associated with a decreased risk (chi(2) = 27.6, p < 0.001). CONCLUSION: Risk of ADEs increased with greater age and cognitive impairment but decreased with the use of NHPs.     

Neuropsychological predictors of self-neglect in cognitively impaired older people who live alone.

OBJECTIVE: The authors examined the accuracy of certain neuropsychological tests in the prediction of harm resulting from self-neglect in cognitively impaired seniors who lived alone. METHODS: The study included 130 participants, aged 65 and older, who scored less than 131 on the Dementia Rating Scale. Neuropsychological tests were administered at baseline, resulting in eight predictive scores. Informants and primary care physicians provided information about harm that occurred to the participants during the 18-month prospective follow up. An incident was defined as harmful if it occurred as the result of self-neglect or disorientation and resulted in physical injury or property loss or damage and required emergency interventions. Proportional hazard regression analysis was conducted to examine the predictive relationship between the eight neuropsychological tests and time to incident harm with age, sex, education, the Charlson Comorbidity Index, and the Mini-Mental State Examination included in the model as covariates. RESULTS: Twenty-seven participants experienced harm during the 18-month follow-up period. A proportional hazards model indicated that three neuropsychological tests, which measured recognition memory, executive functioning, and conceptualization, were independent risk factors for harm. CONCLUSIONS: These findings provide insight into why harm occurred in these cognitively impaired elders who lived alone. They also support the ecologic validity of these tests and suggest directions for the development of intervention strategies for harm prevention.     

Longitudinal follow-up of depressive symptoms among normal versus cognitively impaired elderly

OBJECTIVES: This prospectively designed longitudinal study assesses prevalence, incidence and prognosis of depressive symptoms among cognitively normal elderly volunteers compared with patients with mild cognitive impairment (MCI), dementia of Alzheimer type (DAT), and vascular dementia (VAD). Possible relationships between depressive symptoms, cognitive performance, disease types, and effects of antidepressant treatment were analyzed. METHODS: Two hundred and ninety four subjects exhibiting different levels of cognitive performance were admitted to this study. Demographics, cardiovascular and neurodegenerative risk factors, together with measures of neuropsychological test performance, were obtained at sequential visits. Depressive symptoms were selectively treated with antidepressant medications. RESULTS: One hundred and forty six subjects with normal cognition, 19 subjects with MCI, 42 patients with DAT, and 32 patients with VAD were followed for a mean of 3.5 years. With the passage of time, there were trends showing prevalence of depressive symptoms to decrease among DAT and to increase among VAD patients. VAD patients exhibited the highest incidences of new-onset depressive symptoms, followed in incidence by DAT and MCI groups. Depressive symptoms among VAD and MCI patients were more persistent and refractory to antidepressant medications than for DAT patients. Trends suggested that antidepressant treatment might benefit MCI and VAD subjects more than DAT patients. Motivationally related depressive symptoms accounted for major components of elevated Hamilton depression rating scale scores. CONCLUSIONS: Depressive symptoms among DAT patients have higher rates of spontaneous resolution, without requiring intensive drug treatment, than among VAD patients in whom depressive symptoms are more persistent and refractory to drug treatment. Early depressive symptoms among subjects with MCI may represent a preclinical sign and should be considered as a risk factor for impending DAT or VAD among the elderly.     

Prevalence and correlates of neuropsychiatric symptoms in Parkinson's disease without dementia

A cross‐sectional study of the profile of psychiatric symptoms and their relationships to medications, executive performance, and excessive daytime somnolence (EDS) was conducted on 1351 consecutive Parkinson's disease patients without dementia (PD‐ND). Ratings were: neuropsychiatric inventory (NPI); hospital anxiety and depression scale (HADS); executive performance (semantic, phonemic, and alternating verbal fluencies); and the Epworth sleepiness scale (ESS). Eighty‐seven percent of the subjects reported at least one psychiatric symptom. The most common were depression (70%), anxiety (69%), apathy (48%), and irritability (47%). Fifty percent of the patients had HADS‐depression scores ranging from possible (8–10; 22%) to probable (≥11; 28%) depression. Executive impairment was found in 41% and EDS in 26% of subjects. All considered variables were significantly more common with longer duration and more severe disease. Only depression appeared to be influenced by type of medication, being less prevalent among patients treated with DAs. Five NPI clusters were identified among patients scoring ≥1 on the NPI (87.3%): patients exhibiting predominantly apathy (12.7%), psychosis (3%), depression (13%), anxiety (15.6%), and “low‐total NPI” (43.2%). Neuropsychiatric symptoms are common in nondemented PD patients suggesting that they are an integral part of PD from the beginning of the disease and appears more related to disease progression than to the type of antiparkinsonian medication. Apathy emerged as an independent construct in PD‐ND, indicating the need to address specific therapeutical approaches targeted toward this particular symptom. © 2008 Movement Disorder Society     

Neuropsychological profile of cognitively impaired patients with schizophrenia

OBJECTIVE: Our purpose in undertaking the present study was to explore the existence of specific areas of cognitive deficits within the context of generalized poor performance in a group of Greek patients with schizophrenia. We also sought to identify any patients who might be cognitively normal. METHOD: Participants were 70 patients with schizophrenia and 42 healthy control subjects. The 2 groups were matched on age and male-female ratio but differed in their level of education. A battery of neuropsychological tests was selected to assess executive functions/abstraction, fluency, verbal and spatial working memory, verbal and nonverbal memory, attention, visuospatial ability, and psychomotor speed. RESULTS: Patients with schizophrenia performed more poorly than healthy control subjects, when we controlled for differences in level of education, on executive functions, working memory, verbal memory, nonverbal memory, fluency, visuospatial ability, and attention. In contrast, no significant differences were found between the 2 groups on psychomotor speed. Patients showed a more pronounced deficit on executive functions, verbal and visual memory, and visuospatial ability. Overall, 13% to 62% of the patients with schizophrenia scored within 1 SD of the mean z scores of healthy control group depending on the cognitive domains examined. In the entire sample of patients with schizophrenia, however, no individual scored within 1 SD of the mean z scores of the control group in all cognitive domains. CONCLUSIONS: We found a generalized deficit in cognitive functioning in a group of patients with schizophrenia. We failed to find any individual patients who were healthy across all cognitive areas. The current neuropsychological profile, indicating widespread impairment, is comparable to that reported in the international literature and thus appears to be characteristic of schizophrenia. Our findings of increased difficulties with executive functions, verbal and visual memory, and visuospatial ability support previous suggestions of generalized brain dysfunction in the pathophysiology of schizophrenia.     

The prevalence of neuropsychiatric disorders in a nursing home population

The prevalence of neuropsychiatric disorders and other medical illnesses was investigated in 65 nursing home residents. The authors found neuropsychiatric disorders to be present in 94% of the sample. The neuropathologic causes of these syndromes were found to be more diverse than in previous studies. The most frequent causes were degenerative, vascular, and toxic. The most common psychiatric syndromes that resulted from these neuropathologic disorders were dementia syndrome (72%), organic personality syndrome (14%), and organic psychotic disorders (12%). The most common behavioral problems, agitation and aggression, most likely reflected the high prevalence of frontal lobe damage and affected 48% of the sample. Other non-neuropsychiatric medical problems were significantly less common. While only 4% of the sample had no neuropsychiatric diagnosis, 39% had no other non-neuropsychiatric diagnosis. These results suggest that the nursing home is not used as a referral source for chronic medical conditions in general but almost exclusively for the care of chronic neuropsychiatric disorders.
