Hypertension and stroke in centenarians, Okinawa, Japan

OBJECTIVE: To investigate the relationship between a history of hypertension, cigarette smoking and alcohol intake and the lifetime prevalence of stroke in the oldest-old population. DESIGN: A cross-sectional study. SUBJECTS: All of the Japanese centenarians in the Okinawa Prefecture (266 men and 1,378 women). METHODS: Okinawa Prefectural Government conducted health surveys among all of the centenarians in Okinawa. The variables used for analysis were sex, history of stroke, age at the first diagnosis of stroke, history of hypertension, cigarette smoking and alcohol intake. We used multiple logistic regression analysis taking the history of stroke as the dependent variable. RESULTS: The lifetime prevalence value for stroke was 11.0% in Japanese centenarians. Hypertension was independently associated with an increased lifetime prevalence of stroke (adjusted odds ratio = 2.97 and 95% confidence interval: 2.16-4.08). There was no material relationship between sex, cigarette smoking, oralcohol intake and the prevalence of stroke. When the lifetime prevalence of stroke was divided according to whether stroke had been diagnosed for the first time at the age of 90 years or less or over the age of 90, a significant positive association between hypertension and stroke was more pronounced in centenarians with a diagnosis of stroke at the age of 90 years or less than in those over the age of 90. CONCLUSIONS: The findings suggest that hypertension may increase the likelihood of stroke in Japanese centenarians in Okinawa although the association between hypertension and stroke was more pronounced in those having stroke at 90 years or younger.     

Age at onset, childhood psychopathology, and 2-year outcome in psychotic bipolar disorder

OBJECTIVE: The relationships of age at onset and childhood psychopathology to 2-year clinical and functional outcomes in first-admission patients with bipolar I disorder were examined. METHOD: Patients with bipolar I disorder (N=123) presenting with psychotic symptoms were followed over a 2-year period. Age at onset was stratified into <19 and >or=19 years. Childhood psychopathology was categorized as behavior problems, other psychopathology, and none. Functional and clinical outcomes were rated with standard measures. RESULTS: Childhood psychopathology and age at onset were independently related to poorer functional and clinical outcome. In the multivariate models that included psychopathology, age at onset, sex, and education, early age at onset was related to incomplete remission, and childhood psychopathology was related to functional outcome. CONCLUSIONS: Childhood psychopathology and age at onset contribute independently to outcomes of bipolar disorder. Childhood psychopathology is a much stronger predictor of functioning than age at onset.     

Influence of cognitive functioning on functional status in an older population: 3- and 6-year follow-up of the Maastricht Aging Study

BACKGROUND: To date, it remains unclear to what extent cognitive competence is related to a change in general functional status in older adults. OBJECTIVES: To evaluate both the cross-sectional and the longitudinal relation between cognitive functioning and functional status. METHODS: Sensorimotor speed, memory, and executive functioning were assessed in a large population of healthy adults aged 60 years and older (n = 485) who participated in the Maastricht Aging Study. Data from the baseline (1993-1995), three-year follow-up, and six-year follow-up were used. Functional status was measured using the SF-36, which was coded into a physical and a mental component summary measure. RESULTS: After adjustment for age, sex, and educational level, a high level of cognitive functioning appeared to be associated with better functional status in the cross-sectional analysis. Longitudinal analyses demonstrated, that cognitive functioning was not a predictor of functional status three or six years later. CONCLUSIONS: Thus while cognitive functioning is useful clinically for predicting the short-term functional status of an older person, it is not useful for predicting that person's long-term (>3 years) functional status and thus the period of validity of the results of these tests in answering such questions is limited.     

Retrospective age at onset of bipolar disorder and outcome during two-year follow-up: results from the STEP-BD study

Objective:  Symptoms of bipolar disorder are increasingly recognized among children and adolescents, but little is known about the course of bipolar disorder among adults who experience childhood onset of symptoms.
Methods:  We examined prospective outcomes during up to two years of naturalistic treatment among 3,658 adult bipolar I and II outpatients participating in a multicenter clinical effectiveness study, the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD). Age at illness onset was identified retrospectively by clinician assessment at study entry.
Results:  Compared to patients with onset of mood symptoms after age 18 years (n = 1,187), those with onset before age 13 years (n = 1,068) experienced earlier recurrence of mood episodes after initial remission, fewer days of euthymia, and greater impairment in functioning and quality of life over the two-year follow-up. Outcomes for those with onset between age 13 and 18 years (n = 1,403) were generally intermediate between these two groups.
Conclusion:  Consistent with previous reports in smaller cohorts, adults with retrospectively obtained early-onset bipolar disorder appear to be at greater risk for recurrence, chronicity of mood symptoms, and functional impairment during prospective observation.     

Depression, perceived family criticism, and functional status among older, primary-care patients.

OBJECTIVE: Relatively little research has examined the role of family factors in later-life depression, particularly in the broad range of depressive conditions seen in primary care. Authors tested the hypotheses that 1) perceived family criticism is independently associated with depression, 2) that family criticism and depression are independently associated with functional disability, and 3) that perceived family criticism moderates the association between depression and functional disability. METHODS: This cross-sectional study recruited 379 adults age > or =65 years from primary-care practices. Study measures included the Structured Clinical Interview for DSM-IV, the Hamilton Rating Scale for Depression, the Family Emotional Involvement and Criticism Scale, and several measures of functional disability. Multiple regression determined independent associations, and a multiplicative interaction term tested the moderator model of the third hypothesis. RESULTS: Perceived family criticism was independently associated with depression diagnosis and depressive symptoms. Depression diagnosis, depressive symptoms, and perceived family criticism were each independently associated with functional status. Perceived family criticism did not moderate the association between depressive symptoms and functional status in the overall study group, although it did moderate the association between depression diagnosis and instrumental activities of daily living when only early-onset depressed patients were included. CONCLUSIONS: Authors confirmed the first and second hypotheses; however data did not support the third hypothesis. These results provide support for clinicians to attend to quality of primary family relationships and perceived criticism in depressed older adults and for researchers to consider aspects of family functioning as covariates or potential targets for intervention studies.     

Poor mental and physical health differentially contributes to disability in hospitalized geriatric patients of different ages

OBJECTIVE: To evaluate the relationship between depressive symptoms, cognition and somatic diseases on functional status of geriatric patients at hospital discharge. METHOD: Patients 65+ years consecutively admitted to the acute care geriatric ward of the Internal Medicine Department I, Civil Hospital of Brescia, Italy, from February 1998 to December 2000 (n = 830) were examined. Functional disability was defined as need of physical assistance in at least one of the basic Activities of Daily Living (ADL). The Greenfield Index of Disease Severity (IDS) and the Geriatric Index of Comorbidity (GIC) were used to measure number and severity of diseases. The Mini-Mental State Examination (MMSE) assessed cognitive status and the Geriatric Depression Scale (GDS) measured depressive symptoms. RESULTS: Prevalence of functional disability at discharge was 29.3% in the younger age group (65-74 years) and 55.2% in the older age group (75+ years). Using logistic regression models, older age, poorer cognitive status, and depressive symptoms were independently associated with functional disability in the younger and older age group, respectively. Additionally cognitive impairment and depressive symptoms showed an additive association with disability, especially in younger patients, while comorbidity was correlated with functional status only in the oldest old, in particular among those who were cognitively impaired. CONCLUSION: Functional disability after acute hospitalization is highly prevalent in geriatric patients. Depressive symptoms, comorbidity, and cognitive impairment often coexist, interact and are differentially associated with function depending on age. Considering that depressive symptoms are a modifiable problem, their detection in hospital settings may help clinicians in targeting subjects at high risk of functional disability.     

Relationship of neuropsychological performance to functional status in nursing home residents and community-dwelling older adults.

OBJECTIVES: The authors examined the association between neuropsychological tests of executive functioning and episodic memory and functional disability in nursing home residents versus community-dwelling older adults. METHODS: The neuropsychological performance of 96 residents from the Jewish Home and Hospital, Bronx, NY and 192 gender- and age-matched older adults from residential communities in the New York metropolitan area was assessed in eight tasks (Word List Recall, Delayed Recall, Recognition, Boston Naming, Verbal Fluency, Trailmaking A and B, and Digit Symbol Substitution). Functional status was derived from the Clinical Dementia Rating scale (CDR) extended activities of daily living scores. Regression analyses were performed to test for differences in cross-sectional age-gradients for cognitive and functional status between nursing home residents and community-dwellers. Furthermore, regression analyses, controlling for age, gender, dementia status, and education, were performed to determine the association between neuropsychological performance and functional status, comparing domains of executive functioning and memory. RESULTS: Community-dwelling older adults showed age-related deficits both in overall cognitive status and functional disability, which were larger in nursing home residents. Executive functioning was associated with functional disability beyond the effects of age, gender, education, dementia status, residential status, overall cognitive status, memory, and cognitive speed. CONCLUSION: Executive functioning is associated with functional deficits in both community-dwelling older adults and nursing home residents. Measures of executive functioning may prove useful in intervention studies aimed at delaying institutionalization.     

Heterogeneity in functional status among older outpatients with schizophrenia: employment history,living situation,and driving

Schizophrenia and aging are both risk factors for deficits in independent functioning, yet relatively few studies have examined the level and predictors of functional status of older outpatients with schizophrenia. We compared employment history, current living situation, and driving status of 83 middle-aged and elderly outpatients with schizophrenia (mean age 59 years), and 46 demographically equivalent normal comparison subjects. We also examined the relationships of neuropsychological functioning and psychiatric symptoms to these aspects of everyday functioning. The schizophrenia patient group had consistently worse functional status than the normal comparison group, but 30% of the patients were employed at least 50% of the time during their post-schizophrenia-onset adult lives, 73% were living in a house or apartment and responsible for meeting most of their own daily needs, and 43% were current drivers. Severity of negative symptoms (but not that of positive symptoms) was inversely correlated with functional status. Worse performance on a neuropsychological battery was generally associated with worse functional status. These findings counter notions that functional impairment is inevitable in older schizophrenia patients, and highlight the importance of assessment of functional skills and possibly targeting them as a treatment focus.     

Genes related to vascular disease (APOE, VLDL-R, DCP-1) and other vascular factors in late-life depression.

OBJECTIVE: The authors asked whether polymorphic variation at three genes related to vascular disease, and other vascular disease risk factors, determine late-life depression. METHODS: A group of 370 participants, representing 57% of survivors of an initial cohort of 1,083 participants in the Medical Research Council treatment trial of hypertension in older adults, had been screened for depression at baseline and were traced and genotyped for genetic analysis 11 years later. Genetic analyses were performed to establish variability at three polymorphisms related to vascular disease: APOE encoding for apolipoprotein-E, VLDL-R encoding for the VLDL cholesterol-receptor, and DCP-1 encoding for angiotensin-converter enzyme. Information on vascular disease and its risk factors (ECG ischemia or arrhythmia, body mass index, serum cholesterol, smoking status, and systolic/diastolic blood pressure) and cognitive functioning was also available from baseline. RESULTS: The authors found no association between the three studied polymorphisms and depression. Female gender, higher diastolic blood pressure, poorer cognitive functioning, and smoking status at baseline were all associated with depression independently of antidepressant and NSAIDs use, age, ECG-established vascular disease, and the remaining vascular disease risk factors studied. CONCLUSIONS: This study found no association between late-life depression and three polymorphisms related to vascular disease. Depression was found to independently associated with smoking, female gender, poorer cognitive functioning, and higher diastolic blood pressure. Taken together, this study does not seem to support the notion of a specific link between the studied vascular risk factors or these vascular-related loci and late-life depression.     

Clinical and psychological correlates of poststroke fatigue. Preliminary results

BACKGROUND AND PURPOSE: Although poststroke fatigue concerns almost 60% of patients, still little is known about its pathogenesis and contributing factors. Therefore, the purpose of this study was to evaluate the severity of fatigue in terms of its impact on physical, psychological and social functioning as well as to determine the relation between fatigue and clinical, demographic and psychological factors. MATERIAL AND METHODS: Patients (n = 50) with acute first-ever stroke admitted to the neurological department were interviewed at 3 months after discharge. Poststroke fatigue was assessed using the Polish version of the Fatigue Impact Scale. Neurological status was examined with the Scandinavian Stroke Scale, functional status with the Barthel Index, and emotional status with the Beck Depression Inventory. Styles of coping with stress were identified using the Coping Inventory for Stressful Situations. Sex, age, type of stroke and lesion location were documented as well. RESULTS: Ninety percent of patients demonstrated high level of fatigue in physical functioning, 16% in the psychological domain, and 18% in the social domain. In the univariate analyses, impact of fatigue on patients functioning significantly correlated with age, lower mood, neurological and functional status, as well as with styles of coping. Emotion-oriented coping was associated with lower level of fatigue, whereas the reverse was found regarding task-oriented coping. In the multivariate analyses the emotion-oriented style of coping was the most important correlate of fatigue. CONCLUSIONS: The causes of poststroke fatigue appear to be multifactorial. Psychological factors, especially coping strategies, might be an important area for future interventions.     

Affect and loneliness among centenarians and the oldest old: the role of individual and social resources

Objectives: Affect and loneliness are important indicators of mental health and well-being in older adulthood and are linked to significant outcomes including physical health and mortality. Given a large focus on young–old adults within gerontological research, the primary aim of this study was to examine the ability of individual and social resources in predicting affect and loneliness within a sample of oldest-old individuals including centenarians, an understudied population.

Methods: Participants were assessed during the most recent cross-sectional data collection of the Georgia Centenarian Study. The eligible sample included 55 octogenarians (M?=?83.70 years, SD?=?2.68; range?=?81–90) and 77 centenarians (M?=?99.78 years, SD?=?1.64; range?=?98–109). Subjects scored 17 or greater on the Mini-Mental Status Exam and completed mental health assessments.

Results: Hierarchical regression analyses were conducted to examine the relation of affect and loneliness with demographic characteristics, physical and social functioning, cognition, and personality. Within this sample of cognitively intact oldest old, measures of executive control and cognitive functioning demonstrated limited association with mental health. Personality, specifically neuroticism, was strongly related to mental health indicators for both age groups and social relations were particularly important associates of centenarians’ mental health.

Discussion: Findings indicate the distinctiveness of mental health indicators and the need to distinguish differential roles of individual and social resources in determining these outcomes among octogenarians and centenarians     

Impact of psychometrically defined deficits of executive functioning in adults with attention deficit hyperactivity disorder

OBJECTIVE: The association between deficits in executive functioning and functional outcomes was examined among adults with attention deficit hyperactivity disorder (ADHD). METHOD: Subjects were adults who did (N=213) and did not (N=145) meet DSM-IV criteria for ADHD. The authors defined having deficits in executive functioning as having at least two measures of executive functioning with scores 1.5 standard deviations below those of matched comparison subjects. RESULTS: Significantly more adults with ADHD had deficits of executive functioning than comparison subjects. Deficits of executive functioning were associated with lower academic achievement, irrespective of ADHD status. Subjects with ADHD with deficits of executive functioning had a significantly lower socioeconomic status and a significant functional morbidity beyond the diagnosis of ADHD alone. CONCLUSIONS: Psychometrically defined deficits of executive functioning may help identify a subgroup of adults with ADHD at high risk for occupational and academic underachievement. More efforts are needed to identify cost-effective approaches to screen individuals with ADHD for deficits of executive functioning.     

Neurocognitive dysfunction and psychosocial outcome in patients with bipolar I disorder at 15‐year follow‐up

Burdick KE, Goldberg JF, Harrow M. Neurocognitive dysfunction and psychosocial outcome in patients with bipolar I disorder at 15‐year follow‐up. Objective: Despite increasing interest in cognitive dysfunction in bipolar disorder, little is known about its impact on functional outcome relative to affective symptoms. Method: A total of 33 bipolar I subjects were evaluated at index hospitalization and prospectively followed up 15 years later. Affective symptoms, cognition, global functioning, work, and social adjustment were assessed at follow‐up and analyzed by linear regression. Results: Global functional impairment was significantly associated with poor performance on a cognitive measure of processing speed (WAIS Digit Symbol). Digit symbol performance also was the sole significant predictor of social functioning. Neither symptom severity nor course of illness features significantly contributed to global and social functioning. In contrast, verbal learning deficits, recent depression, and lifetime hospitalizations all were independently associated with work disability. Conclusion: Processing speed is robustly associated with social and global functioning in bipolar disorder. Poor work functioning is significantly related to subsyndromal depression, course of illness, and verbal learning deficits. Cognitive and mood symptoms warrant consideration as independent determinants of functioning in patients with bipolar disorder many years after an index manic episode.     

The EEG in centenarians.

1. The EEGs of ten centenarians were described. 2. In most healthy centenarians, posterior dominant rhythms are within the lower part of the alpha range (average 8.62 c/sec). 3. Although slowing of the posterior dominant rhythm at age 100 is greater than in younger groups, there is no evidence in this study of a progressive decrease in frequency during the two decades between 80 and 100 years. 4. Most records of centenarians contained other abnormalities, either of diffuse slowing or of slow wave foci, the latter most often in the left temporal area. 5. The relationship of the observed EEG changes to the process of aging as distinct from reduced cerebral metabolism and blood flow resulting from disease is discussed.     

Relationship of the Brief UCSD Performance-based Skills Assessment (UPSA-B) to multiple indicators of functioning in people with schizophrenia and bipolar disorder

Mausbach BT, Harvey PD, Pulver AE, Depp CA, Wolyniec PS, Thornquist MH, Luke JR, McGrath JA, Bowie CR, Patterson TL. Relationship of the Brief UCSD Performance‐based Skills Assessment (UPSA‐B) to multiple indicators of functioning in people with schizophrenia and bipolar disorder. Bipolar Disord 2010: 12: 45–55. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objective: This study assessed the relationship between multiple indicators of ‘real‐world’ functioning and scores on a brief performance‐based measure of functional capacity known as the Brief University of California San Diego (UCSD) Performance‐based Skills Assessment (UPSA‐B) in a sample of 205 patients with either serious bipolar disorder (n = 89) or schizophrenia (n = 116). Methods: Participants were administered the UPSA‐B and assessed on the following functional domains: (i) independent living status (e.g., residing independently as head of household, living in residential care facility); (ii) informant reports of functioning (e.g., work skills, daily living skills); (iii) educational attainment and estimated premorbid IQ as measured by years of education and Wide Range Achievement Test reading scores, respectively; and (iv) employment. Results: Better scores on the UPSA‐B were associated with greater residential independence after controlling for age, diagnosis, and symptoms of psychopathology. Among both bipolar disorder and schizophrenia patients, higher UPSA‐B scores were significantly related to better informant reports of functioning in daily living skills and work skills domains. Greater estimated premorbid IQ was associated with higher scores on the UPSA‐B for both schizophrenia and bipolar disorder participants. Participants who were employed scored higher on the UPSA‐B when controlling for age and diagnosis, but not when controlling for symptoms of psychopathology. Conclusions: These data suggest the UPSA‐B may be useful for assessing capacity for functioning in a number of domains in both people diagnosed with schizophrenia and bipolar disorder.     

Predictors of functional outcome in individuals at high clinical risk for psychosis at six years follow-up

BackgroundThe long-term functional status of subjects at ultra high risk for psychosis (HR) is relatively under investigated. This study explores baseline predictors of long-term functional outcome in HR subjects who did not convert to psychosis during a 6 years follow-up period.MethodsA total of 154 HR were followed up for an average of 6 years. The primary outcome variable was global assessment of functioning at the last follow-up visit as assessed with the Global Assessment of Functioning tool. A multinomial logistic regression was performed to identify potential predictors of functional outcome.ResultsBaseline and follow-up data on functioning was available for 92 HR. Twenty-four (43%) individuals who did not convert to psychosis reported poor functioning at follow-up. Baseline scores in the GAF (Exp(b) = 0.857; 95% CIs: 0.75/0.97), employment status (Exp(b) = 0.029; 95% CIs: 0.00/0.268), and CAARMS total scores (Exp(b) = 1.976; 95% CIs: 1.00/1.14) predicted functional outcome in HR subjects at 6 years.ConclusionsDespite the preventive treatments received, many individuals who did not convert to full-blown psychosis in the longer term do not functionally remit. These individuals are lower functioning, unemployed and have higher symptom loading at the time of their presentation to the prodromal clinic. Our study suggests the need for innovative treatments targeting long term functional status beyond the prevention of psychosis onset in the HR population.     

Presurgical seizure frequency and tumoral etiology predict the outcome after extratemporal epilepsy surgery

OBJECTIVE: To examine the predictive value of demographic data for the seizure outcome after extratemporal epilepsy surgery. METHODS: Eightyone patients who underwent resective extratemporal epilepsy surgery were retrospectively studied concerning (a) age at surgery, (b) onset of epilepsy, (c) duration of epilepsy, (d) number of seizures at the time of presurgical evaluation, (d) number of presurgically tested antiepileptic substances and (f) number of seizure types. The data were correlated to the postoperative seizure outcome after two years. RESULTS: 33 patients (40.7%) were seizure free two years after surgery. Univariate and multivariate analysis revealed that both tumor etiology and low presurgical seizure frequency were independently associated with seizure freedom after epilepsy surgery. The recurrence rate in patients with one or more seizures per day was more than two-fold if compared with patients with fewer seizures. The remaining demographic factors did not show a significant association with seizure outcome in our 81 patients. CONCLUSIONS: Fewer than daily seizures prior to surgery and a tumoral etiology independently increase the likelihood of remaining seizure free two years after extratemporal epilepsy surgery.     

Health-related quality of life and functioning of middle-aged and elderly adults with bipolar disorder

OBJECTIVE: Data characterizing bipolar disorder in older people are scarce, particularly on functional status. We evaluated health-related quality of life and functioning (HRQoLF) among older outpatients with bipolar disorder as well as the relationship of HRQoLF to bipolar illness characteristics. METHOD: We compared community-dwelling middle-aged and older adults (age range, 45 to 85 years) with bipolar disorder (N=54; mean age=57.6 years), schizophrenia (N=55; mean age=58.5 years), or no psychiatric illnesses (N=38; mean age=64.7 years) on indicators of objective functioning (e.g., education, occupational attainment, medical comorbidity) and health status (e.g., Quality of Well-Being scale [QWB] and the Medical Outcomes Study-Short Form Health Survey [SF-36]). Within the group with bipolar disorder, we examined the relationship between HRQoLF and clinical variables (e.g., phase and duration of illness, psychotic symptoms, cognitive functioning). RESULTS: Patients with bipolar disorder were similar in educational and occupational attainment to the normal comparison group, but they obtained lower scores on the QWB and SF-36 (with large effect sizes). Compared with schizophrenia, bipolar disorder was associated with better educational and work histories but similar QWB and SF-36 scores and more medical comorbidity. Patients in remission from bipolar disorder had QWB scores that were worse than those of normal comparison subjects. Greater severity of psychotic and depressive symptoms and cognitive impairment were associated with lower HRQoLF. CONCLUSIONS: Bipolar disorder was associated with substantial disability in this sample of older adults, similar in severity to schizophrenia. Remission of bipolar disorder was associated with significant but incomplete improvement in functioning, whereas psychotic and depressive symptoms and cognitive impairment seemed to contribute to lower HRQoLF.     

Loss of ability to work and ability to live independently in Parkinson's disease

ObjectiveAbility to work and live independently is of particular concern for patients with Parkinson’s disease (PD). We studied a series of PD patients able to work or live independently at baseline, and evaluated potential risk factors for two separate outcomes: loss of ability to work and loss of ability to live independently.MethodsThe series comprised 495 PD patients followed prospectively. Ability to work and ability to live independently were based on clinical interview and examination. Cox regression models adjusted for age and disease duration were used to evaluate associations of baseline characteristics with loss of ability to work and loss of ability to live independently.ResultsHigher UPDRS dyskinesia score, UPDRS instability score, UPDRS total score, Hoehn and Yahr stage, and presence of intellectual impairment at baseline were all associated with increased risk of future loss of ability to work and loss of ability to live independently (P ≤ 0.0033). Five years after initial visit, for patients ≤70 years of age with a disease duration ≤4 years at initial visit, 88% were still able to work and 90% to live independently. These estimates worsened as age and disease duration at initial visit increased; for patients >70 years of age with a disease duration >4 years, estimates at 5 years were 43% able to work and 57% able to live independently.ConclusionsThe information provided in this study can offer useful information for PD patients in preparing for future ability to perform activities of daily living.
