Disease profile of 400 institutionalized mentally retarded patients in Kuwait.

In this preliminary report we summarize the results of a 4-year multidisciplinary systematic, etiological clinicogenetic survey of 400 institutionalized mentally retarded patients in Kuwait. All had an intelligence quotient below 50. A constitutional disorder, as the direct cause of the mental retardation, was found in 203 patients (50.75%)): a chromosomal abnormality in 37 (9.25%), Mendelian disorders in 137 (34.25%), MCA/MR in 22 (5.55%) and CNS malformations in 7 cases (1.75%). In 157 patients (39.35%) a pre-, peri or postnatal cause was ascertained. No etiological diagnosis was detected in 40 patients (10%). A detailed analysis of the "disease profile" is given and compared with the results of previous diagnostic genetic surveys among different institutionalized mentally retarded populations in Western and developing countries.

Alcohol-related dementia in the institutionalized elderly.

This study examined the distribution of alcohol-related and other dementias in a sample of 130 cognitively impaired residents of long-term care facilities in a Northern Ontario community. Study procedures entailed standardized psychiatric, neurological, and neuropsychological evaluations. Diagnoses of dementia of the Alzheimer type (DAT) and vascular dementia were based on criteria of the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association. The diagnosis of alcohol-related dementia (ARD) was based on extensive review of medical history to assess before alcohol abuse and stabilization or improvement in cognitive functioning following institutionalization in conjunction with no other identifiable cause of dementia. ARD comprised 24% of this population compared with DAT (35%), vascular dementia (19%), and other causes (22%). The ARD group was, on average, 10 years younger than the other groups. It had nearly twice the average length of institutionalization and had milder cognitive impairment on both clinical ratings and neuropsychological tests. A diagnosis of ARD was present in the medical records for only 25% of patients in this group. These findings suggest that ARD may be more common than previously suspected in the distribution of dementias in long-term care facilities.

Daily sleep patterns observed among institutionalized elderly residents.

The sleep/wake patterns of 16 institutionalized demented women were visually monitored hourly for 14 consecutive days. Individual mean total sleep time varied markedly from 5.0 to 12.1 hours per 24 hours. Unexpectedly, amounts of day sleep and night sleep correlated positively, suggesting a general sleep tendency manifested throughout the 24-hour day. Consistent individual sleep patterns and high inter-day correlations were found. A high degree of individuality in the sleep/wake patterns was also found, contrary to expectations that elderly obtain less sleep than others. Night sleep in the institutionalized elderly was not lessened by daytime sleep. Visual monitoring of sleep/wake patterns generated reliable data.

Longitudinal study of death and institutionalization in patients with primary degenerative dementia.

We studied the outcome of 101 patients with primary degenerative dementia. The patients were outpatients at the time of the initial evaluation, and all had family caregivers. There were substantial differences in mortality and institutionalization between the mild and advanced patients, as defined by scores on mental status examination. Similar differences in those two outcomes were also evident when the patients were stratified by scores on activities of daily living and disruptive behavior assessments. Thus, certain patient characteristics may be of value in predicting risk for institutionalization and death.

Asymptomatic bacteriuria, urinary antibody, and survival in the institutionalized elderly.

OBJECTIVE: To compare clinical status of elderly institutionalized subjects with asymptomatic bacteriuria and normal urinary antibody to those with elevated urinary antibody to the major outer membrane of Escherichia coli. DESIGN: Retrospective review. SETTING: Long term facility for the elderly. PARTICIPANTS: Convenience sample of 63 elderly subjects, 26% of those resident in the institution, aged 78.8 +/- 8.4 years with urine specimens collected and stored in 1987. MAIN OUTCOME MEASURES: Differences in clinical or functional status, demographic features, and outcome during 3-years follow-up between bacteriuric subjects with normal and elevated urine antibody. RESULTS: Thirteen subjects had no bacteriuria, and 12 had infrequent, intermittent bacteriuria; 38 (60%) had persistent bacteriuria, including four with frequent, intermittent infections. In the persistently bacteriuric group, 18 (47%) had persistently elevated urine antibody. There was no significant differences between bacteriuric residents with normal vs elevated urine antibody in clinical or functional status, age, duration of residence, or infecting organisms. However, 11 of 20 in the cohort with normal urine antibody were alive at 3 years compared to 3 of 18 with elevated urine antibody (P = 0.014). CONCLUSIONS: Elderly institutionalized subjects with persistent bacteriuria and elevated urine antibody have decreased survival compared to those with normal urine antibody. No differences in underlying illness or clinical course to explain this survival difference were identified.

Prevalence of associated diseases in different types of dementia among elderly institutionalized patients: analysis of 3447 records.

OBJECTIVE: To determine the prevalence of dementia in a population of hospitalized or institutionalized elderly patients, and that of associated diseases according to dementia type. DESIGN: Retrospective analysis of a database of diagnostic codes. SUBJECTS: All patients admitted to 1 of the 4 geriatric units participating in the study at the Charles Foix Hospital between 1980 and 1989. MEASUREMENTS: All diagnoses mentioned in the discharge summary that could cause or contribute to hospitalization were recorded for each patient. A final list of 54 different diagnoses could be recorded for each patient. Dementia was subdivided into 3 subtypes: Alzheimer dementia (DAT), vascular dementia (VD), and other types of dementia (unclassifiable dementia). MAIN RESULTS: The study involved 3447 patients aged 81.0 +/- 8.3 years, of whom 27.7% were men. Dementia was the most frequent disease in this population (34.3%); Alzheimer disease was responsible for 15%, vascular dementia for 9.5%, and other types for 9.8%. The average number of associated diseases was 3.23 +/- 2.10 in the Alzheimer dementia group, 4.73 +/- 2.38 in the vascular dementia group, and 3.96 +/- 2.26 in the nondemented group. Parkinson disease was present in 15.5% of patients with unclassifiable dementia, compared with 7.6% in the nondemented group (P < 0.001). There were significantly more diseases commonly seen in bedridden patients in the group of patients with both other types of dementia and Parkinson disease than in the group of other types of dementia patients without Parkinson disease (P < 0.01). CONCLUSION: Dementia was the most common disease observed in our elderly institutionalized population. Alzheimer patients had significantly fewer associated diseases than nondemented patients, whereas the reverse was found in the vascular dementia group. The co-existence of Parkinson disease and dementia in our population was associated with the poorest health status, as these patients were more likely to present simultaneously such conditions as pressure sores, incontinence, dehydration, or iatrogenesis.

Energy-containing nutritional supplements can affect usual energy intake postsupplementation in institutionalized seniors with probable Alzheimer's disease.

OBJECTIVES: To determine whether increases in caloric intake associated with consumption of a mid-morning nutritional supplement for 3 weeks were maintained in the week after stopping the supplement and to investigate the effects of body mass index (BMI) and cognitive and behavioral measures on this response. DESIGN: Secondary analysis of a previously published randomized, crossover, nonblinded clinical trial. SETTING: A fully accredited geriatric care facility affiliated with the University of Toronto. PARTICIPANTS: Thirty institutionalized seniors with probable Alzheimer's disease (AD) who ate independently. MEASUREMENTS: Investigator-weighed food intake, body weight, cognitive (Severe Impairment Battery; Global Deterioration Scale) and behavioral (Neuropsychiatric Inventory--Nursing Home version; London Psychogeriatric Rating Scale) assessments. RESULTS: Individuals who responded successfully to supplementation as indicated by increases in daily energy intake were likely to maintain 58.8% of that increase postsupplementation, although stopping the supplement was associated with decreased habitual energy intake in low-BMI individuals who reduced their daily intakes during supplementation in response to the extra calories. Cognitive/behavioral tests were not reliable predictors of postsupplement intake. CONCLUSION: Institutionalized seniors with probable AD are likely to alter their usual energy intakes to maintain changes resulting from 3 weeks of supplementation. This effect may allow for rotating supplementation schedules in nursing homes that could reduce staff burden, but only for those individuals who are most likely to respond favorably. These data indicate that nutritional supplements and diet plans should be carefully prescribed in low-BMI individuals to limit variability in total energy provided and thus prevent lower-than-normal intake.

Interviewing institutionalized elders: threats to validity.

In the course of an ethnographic study of an intergenerational Geriatric Remotivation Program in a Southeastern U.S. nursing home, we encountered difficulties in interviewing institutionalized elders that threatened the validity of the data. The purpose of this paper is to explicate the difficulties and to recommend strategies for overcoming them. Four main clusters of elder characteristics threatened the validity of data: (1) physical characteristics; (2) cognitive characteristics; (3) affective characteristics; and (4) personal characteristics. Problematic data were categorized as "insufficient," "unclear," "nice" and "emotionally charged." Strategies for increasing validity when interviewing impaired institutionalized elders included increasing the sample size, returning to the setting frequently, lengthening observation periods, recognizing the value of stories, recognizing the value of socializing, using videotapes, collecting both interview and observation data, and having elders view and respond to videotaped recordings.

Denture status and need for prosthodontic treatment among institutionalized elderly in Denmark.

The purpose of the present study was to estimate the realistic need for prosthodontic treatment among institutionalized elderly in Denmark. The study population comprised 486 elderly in nursing homes and 199 in hospital long-term care facilities. The realistic need for treatment was estimated on the basis of the normative and the perceived needs, taking into account the general mental and physical state of each individual as assessed by the charge nurses. The investigation revealed that the majority of the elderly were markedly handicapped, two-thirds were unable to care for themselves, and 15% were in poor mental condition. Among the residents of nursing homes 67% had a normative need for prosthodontic treatment, e.g. new dentures, relining and/or corrections of occlusion, as compared to 71% of the elderly in hospital long-term care facilities. However, only 19% of the nursing home residents and 32% of the elderly in long-term care facilities has a realistic treatment need. The differences between the two groups of elderly are explained by differences in age and general health status. It can be concluded that the realistic need for prosthodontic treatment among institutionalized elderly in Denmark is far from being met, and that this problem can only be solved if given higher priority by the political decision-makers.

Oral health conditions and denture treatment needs in institutionalized elderly people in Japan.

Oral health conditions, including dental conditions, temporomandibular joint (TMJ) conditions, denture status, and oral hygiene status, were assessed on 1908 institutionalized elderly people 65 yr of age and older at 29 of the 30 existing institutions in the city of Kitakyushu, Japan. The percentage of edentulous people was 27% in the 65-74-yr-old group, and increased with age to 56% in the 85 yr and older group. In dentate persons, the mean number of remaining teeth and DF teeth were 13.4 and 8.6, 9.5 and 6.8, and 8.4 and 6.5 in the groups aged 65-74 yr old, 75-84 yr old, and 85 yr and older, respectively. 81% of all the persons examined had no unusual symptoms in their TMJ. A clicking sound was the most frequent symptom (17%). Hygiene of both their teeth and dentures was very poor. Of all the subjects, 36% needed new full and/or partial denture(s), and 41% needed only repair. When the institutionalized elderly people were compared according to their general health condition, no clear differences were observed in percentage of edentulousness, mean number of remaining teeth and DF teeth, and TMJ conditions. However, a higher level of both untreated teeth and denture treatment needs, and poorer oral hygiene, was found in elderly people having poor general health than was observed in those with better health.(ABSTRACT TRUNCATED AT 250 WORDS)

Factors connected with alveolar bone resorption among institutionalized elderly people.

In this socio-dental investigation among 175 institutionalized somatically disabled edentulous elderly people correlations are described between the test subjects' degree of alveolar bone resorption, their gender and age, their duration of edentulousness, and the number of complete dentures worn. All test subjects were interviewed by dental students and clinically examined by dentists. The mandibular alveolar bone resorption was significantly stronger in women than in men and stronger in people who had been edentulous longer. The longer the test subjects had been edentulous and the greater their degree of mandibular alveolar bone resorption was, the more mandibular dentures they had worn. This study among institutionalized elderly people provides for the most part the same results as a previously presented study among much younger people. Obviously, in these respects there are no differences between these groups.

Ethical issues encountered by dentists in the care of institutionalized elders.

Increasing numbers of institutionalized elders have very poor oral health. It has been suggested that ethical problems may influence dentists who attempt to provide oral care for these people, but little attention has been given to research in this area. A qualitative interview method was used to investigate the the views and experiences of dentists working with institutionalized elders. Particular attention was given to the ethical difficulties encountered and how the dentists resolved them. Ten dentists experienced in long-term care were interviewed individually by means of open-ended questions. Thematic analysis identified ethical problems focused on the difficulty of identifying the wishes of patients or predicting the outcome of treatment. The participants reported few difficulties in making clinical decisions in this setting. However, analysis revealed that the ethical perspectives of the dentists varied substantially. Variation was notable particularly in their preference for ideal or practical treatment and in their preference for autonomy of beneficence.

Dental health among institutionalized psychiatric patients in Spain.

This study assessed the dental health of an institutionalized psychiatric population in Spain. The study population was composed of 347 males and 218 females with a mean age of 58.0. The mean length of hospitalization was 26.1 years. The largest proportion of the patients (62%) was diagnosed as having schizophrenia. All subjects were taking psychotropic drugs, with a mean number of 2.1 medications. The sample was examined according to the WHO dental criteria. The DMFT index demonstrated the mean number of carious teeth to be 7.9; missing teeth, 17.0; and filled teeth, 0.0. The DMFT index increased significantly with the patient's age and length of hospitalization. Female and demented patients had significantly higher DMFT scores. These findings suggest that institutionalized patients with mental illness in Spain have extensive untreated dental disease.

Agitation in Dutch institutionalized patients with dementia: factor analysis of the Dutch version of the Cohen-Mansfield Agitation Inventory.

BACKGROUND/AIMS: To establish the construct validity of the Dutch version of the Cohen-Mansfield Agitation Inventory (CMAI-D) in institutionalized patients with dementia. METHODS: The CMAI-D was administered to a large sample of 1,437 patients with moderate to severe dementia, receiving nursing home or outreaching nursing home care. Exploratory factor analysis was used to examine the behavioral dimensions underlying CMAI-D observations. RESULTS: A restricted 3-factor solution showed 3 factors, i.e. physical aggression, physically nonaggressive behavior and verbally agitated behavior, with prevalences of 62, 67 and 62%, respectively. An unrestricted factor solution revealed 3 additional behavioral dimensions: hiding/hoarding, vocal agitation and a factor of miscellaneous items (i.e. repetitious mannerisms, spitting), which occurred in 30, 28 and 35% of the patients, respectively. CONCLUSION: The 3-factor solution of physical aggression, physically nonaggressive behavior and verbally agitated behavior corroborates earlier findings in other patient samples and therefore establishes the construct validity in institutionalized patients with severe dementia. The robustness of these findings across different care settings suggests that agitated behaviors have a common basis. In addition, unrestricted factor analysis showed 3 other important independent behavioral symptoms in dementia, but they are in fact too small to be used as a subscale. These findings might add to the taxonomy of agitation and aggression in dementia.

Prevalence of movement disorders in institutionalized elderly.

The proportion of the population over age 65 years is steadily increasing in Canada and the elderly who are unable to live independently are frequently institutionalized in chronic care facilities. We report our observations on movement disorders (MD) in an institutionalized elderly population of Saskatchewan. A representative sample of 67 subjects aged > or = 65 years had a detailed neurological evaluation on three separate occasions. MD were detected in 13 (19%) cases. The majority, 11 (16%), were females. Seven (10%) had essential tremor, 4 (6%) Parkinson's disease and 2 (3%) had drug-induced parkinsonism.

Microbiology of severe aspiration pneumonia in institutionalized elderly.

We sought to investigate prospectively the microbial etiology and prognostic indicators of 95 institutionalized elders with severe aspiration pneumonia, and to investigate its relation to oral hygiene in using quantitative bronchial sampling. Data collection included demographic information, Activity of Daily Living, Plaque Index, antimicrobial therapy, and outcome. Out of the 67 pathogens identified, Gram-negative enteric bacilli were the predominant organisms isolated (49%), followed by anaerobic bacteria (16%), and Staphylococcus aureus (12%). The most commonly encountered anaerobes were Prevotella and Fusobacterium species. Aerobic Gram-negative bacilli were recovered in conjunction with 55% of anaerobic isolates. The Plaque Index did not differ significantly between the aerobic (2.2 +/- 0.4) and the anaerobic group (2.3 +/- 0.3). Functional status was the only determinant of the presence of anaerobic bacteria. Although seven cases with anaerobic isolates received initially inadequate antimicrobial therapy, six had effective clinical response. The crude mortality was 33% for the aerobic and 36% for the anaerobic group (p = 0.9). Stepwise multivariate analysis identified hypoalbuminemia (p < 0.001) and the burden of comorbid diseases (p < 0.001) as independent risk factors of poor outcome. In view of the rising resistance to antimicrobial agents, the importance of adding anaerobic coverage for aspiration pneumonia in institutionalized elders needs to be reexamined.

Severity of symptoms in chronically institutionalized geriatric schizophrenic patients.

OBJECTIVE: The goal of this study was to characterize the symptoms of geriatric, chronically ill, institutionalized schizophrenic patients and investigate age-related differences in schizophrenic symptoms and cognitive performance from early adulthood to late senescence. METHOD: The Positive and Negative Syndrome Scale and the Mini-Mental State examination were used to assess the schizophrenic symptoms and cognitive performance, respectively, of 393 institutionalized schizophrenic patients stratified into seven groups designated by 10-year age intervals from 25 years to over 85 years. RESULTS: In the comparisons of the seven age groups, significant differences between groups in positive and negative subscale scores on the Positive and Negative Syndrome Scale and in Mini-Mental State scores were revealed. Significant correlations between Mini-Mental State scores and Positive and Negative Syndrome Scale negative symptom scores, but not positive symptom scores, were found for all age groups, except for the youngest patients studied. Current treatment with neuroleptics and prior treatment with ECT, insulin coma, or leukotomy could not account for the poor cognitive performance of the older schizophrenic patients. CONCLUSIONS: The older schizophrenic patients continued to experience psychotic and nonpsychotic symptoms in senescence. Their positive symptoms were moderately less severe and their negative symptoms and cognitive impairment were significantly more severe than those of the younger patients. Somatic treatment appeared not to be responsible for the severe cognitive impairment and negative symptoms of the older patients. These data are relevant to chronically hospitalized geriatric schizophrenic patients but not necessarily to all geriatric schizophrenic patients.

Risk of mortality and institutionalization in demented patients with delusions.

Delusions are a common symptom during the course of dementia. Despite their clinical relevance, however, it is still unclear whether they are of prognostic value. This longitudinal study involving, at baseline, 99 demented Alzheimer disease (AD) and multi-infarct dementia (MID) patients, investigates the risk of mortality and institutionalization at 2 years after discharge from a dementia unit in patients with and without delusions at baseline. Results indicate that the presence of delusions is a significant predictor of future institutionalization (odds ratio 3.6, confidence interval 1.3-9.6), even when confounding factors such as age, educational level, and severity of cognitive and functional impairment are statistically controlled. No significant impact on survival was found.
