Cognitive complaints in patients with untreated obstructive sleep apnea versus patients with neurological and respiratory diseases: prevalence, severity and risk factors.

PURPOSE: Little is known about cognitive complaints (self-reported problems in cognitive functioning) in patients with Obstructive Sleep Apnea (OSA). We compared the prevalence and severity of cognitive complaints in patients with untreated OSA to patients with neurological and respiratory diseases. We also studied risk factors for cognitive complaints across these diseases, including OSA. METHODS: We used a convenience sample to compare untreated OSA patients (N = 86) to patients with stroke (N = 166), primary brain tumor (N = 197) and chronic obstructive pulmonary disease (COPD, N = 204) on cognitive complaints (Cognitive Failure Questionnaire, CFQ), anxiety and depression (Hospital Anxiety and Depression Scale, HADS) and cognitive impairments using neuropsychological tests. We combined all patient groups (OSA, stroke, brain tumor and COPD) and studied potential risk factors (demographic variables, anxiety, depression and cognitive impairments) for cognitive complaints across all patient groups using regression analysis. RESULTS: The prevalence of cognitive complaints was higher in OSA patients and complaints of forgetfulness and distractibility were more severe compared to stroke and primary brain tumor patients, but similar to or lower than COPD patients. Regression analysis for the combined sample of all patient groups showed that cognitive complaints were most strongly associated with symptoms of anxiety and depression. CONCLUSION: A high rate of OSA reported clinically significant cognitive complaints, comparable to other respiratory and neurological patients. Symptoms of anxiety and depression are important risk factors for cognitive complaints in patients with various neurological and respiratory diseases. Future studies should examine the relation between anxiety, depression and cognitive complaints in patients with OSA.

Age of Alzheimer's disease diagnosis in people with Down syndrome and associated factors: Results from the Horizon 21 European Down syndrome consortium.

INTRODUCTION: People with Down syndrome (DS) have high risk of developing Alzheimer's disease (AD). This study examined mean ages of AD diagnosis and associations with co-occurring conditions among adults with DS from five European countries. METHODS: Data from 1335 people with DS from the Horizon 21 European DS Consortium were used for the analysis. RESULTS: Mean ages of AD diagnosis ranged between 51.4 (SD 7.0) years (United Kingdom) and 55.6 (SD 6.8) years (France). Sleep-related and mental health problems were associated with earlier age of AD diagnosis. The higher number of co-occurring conditions the more likely the person with DS is diagnosed with AD at an earlier age. DISCUSSION: Mean age of AD diagnosis in DS was relatively consistent across countries. However, co-occurring conditions varied and impacted on age of diagnosis, suggesting that improvements can be made in diagnosing and managing these conditions to delay onset of AD in DS. HIGHLIGHTS: Mean age of AD diagnosis was relatively consistent between countries Sleep problems and mental health problems were associated with earlier age of AD diagnosis APOE ε4 carriers were diagnosed with AD at an earlier age compared to non-carriers Number of co-occurring conditions was associated with earlier age of AD diagnosis No differences between level of intellectual disability and mean age of AD diagnosis.

Music and Lyric Characteristics of Popular Dutch Funeral Songs.

This study compared the characteristics of 150 songs (Dutch lyrics, N = 47, English lyrics, N = 103), popular at Dutch funerals, to an equal number of non-funeral songs. The variables explored included those linked with the music (valence, energy, danceability, acousticness, key, and tempo); and lyrics, namely: linguistics-related (first-person singular/plural, second-person pronouns; past, present, future tense; expressed emotion (positive, negative words, and the discrete emotional categories anger, anxiety, sadness); and category words (those relating to family, friends, death, religion). Funeral music was lower in valence, energy, and danceability and higher in acousticness than non-funeral music. Furthermore, English funeral music lyrics contained more second-person pronouns and were more future-focused than comparison songs. Funeral lyrics were not particularly negative, but English texts contained more words relating to sadness. In conclusion, funeral music differs in severable notable respects from general popular songs that may reflect the special purpose of this music.

Predicting self-esteem in informal caregivers of people with dementia: Modifiable and non-modifiable factors.

While informal caregivers often feel burdened by the care for a person with dementia, they can also experience positive consequences due to caregiving; caregiver gains. One of these, relatively overlooked, caregiver gains is heightened self-esteem. We assessed the predictive ability of non-modifiable (caregiver sociodemographic- and dementia related-) and modifiable (psychological-) factors for caregiver self-esteem). A cross-sectional study in which 201 caregivers, who spent at least eight hours a week on caring for a community-residing person with dementia, completed a semi-structured interview and five questionnaires. One two-block (1: non-modifiable-; 2: modifiable variables) hierarchic multiple regression analysis was used to assess which variables predicted self-esteem. None of the non-modifiable variables significantly predicted self-esteem. Regarding the modifiable variables, depression and relationship quality with the person with dementia significantly predicted self-esteem (adjusted R2 = .460, ß = -.207, p = .015 and ß = .632, p < .001 respectively). Caregivers who experience a better relationship quality with the person with dementia, and fewer depression symptoms, experience a higher level of self-esteem. Interventions focused on heightening self-esteem should strive to optimize these factors to enhance the lives of informal dementia caregivers.

Episodic memory and executive functioning in informal dementia caregivers.

Objectives: Informal dementia caregivers are thought to experience high levels of depression and burden, which can contribute to worse cognitive functioning. However, poorer cognitive functioning in caregivers is not always found. The current study explored whether caregivers perform better, worse, or similar to non-caregivers on tasks for executive functioning and memory. Whether sociodemographic and psychosocial characteristics are associated with caregivers' performance was also assessed.Methods: One hundred forty-five caregivers completed the Letter Fluency and Category Fluency, the Logical Memory test from the WMS-III, and five questionnaires assessing psychological characteristics. Standardized z-scores (based on age, education, and sex) were calculated using data from a matched control group (187 non-caregivers). One sample z-tests were executed to examine if the caregivers' standardized mean z-score significantly deviated from the population mean of z = 0. The z-scores were used as dependent variables in multivariable regression analyses.Results: The caregivers performed significantly better on Logical Memory - Immediate Recall than non-caregivers (z = 2.92, p = .004). The obtained z-scores on the other tasks did not deviate significantly from 0. Male sex and social reliance predicted higher scores on Category Fluency, but the F-test was non-significant, and the explained variance was low (adjusted R2 = .068).Conclusions: We found no evidence for poorer cognitive performance among informal caregivers compared to non-caregivers. Our results suggest that caregiving for a loved one with dementia does not impair the caregivers' episodic memory or executive functioning when measured cross-sectionally.

Motor Impairment Three Months Post Stroke Implies A Corresponding Cognitive Deficit.

BACKGROUND: While both motor and cognitive impairment are common after stroke, the focus of (early) treatment has always been on motor deficit. AIMS: The objective of the current study was to explore the link between motor and cognitive performance in stroke patients and to examine whether motor performance is associated with cognitive functioning at three months post stroke. METHODS: In both stroke patients (n = 142) and controls (n = 135), with the groups matched on age, gender and premorbid IQ, motor functioning was evaluated using both objective (Purdue Pegboard Test) and subjective measures (specific items from the Frenchay Activities Index and Barthel Index). Cognition, specifically information processing speed, working memory and cognitive flexibility, was assessed using objective tasks. The data were analyzed using Pearson product-moment correlation coefficients and logistic regression. RESULTS: Significant correlations between motor and cognitive functioning were found in stroke patients. The objective motor task was stronger than subjective measures in statistically explaining and predicting cognitive deficit, irrespective of stroke severity. CONCLUSIONS: We conclude that motor impairment at three months post-stroke should serve as a 'red flag' for professionals: cognitive impairment is likely and should also be evaluated.

Course and Predictors of Subjective Cognitive Complaints During the First 12 Months after Stroke.

BACKGROUND: Subjective Cognitive Complaints (SCC) are common after stroke. This study documents the prevalence and course of SCC in the first year after stroke and determines which patient characteristics in the first 3 months predict subsequent SCC at 1-year follow-up. METHODS: Using a longitudinal design, 155 patients (mean age 64.0 ± 11.9 years; 69.7% men) were assessed at 3 and 12 months after stroke. SCC were assessed using the Checklist for Cognitive and Emotional consequences following stroke (CLCE) inventory (content component [CLCE-c] and worry component [CLCE-w]). Potential predictors of 12 months SCC included demographics, stroke severity, objective cognitive impairment, psychological factors (depression, anxiety, perceived stress, fatigue, personality traits, coping style), and activities of daily life functioning assessed at 3 months poststroke. Multiple hierarchical linear regression analyses were used to determine predictors of SCC at 12 months poststroke. RESULTS: SCC remained stable from 3 to 12 months over time (CLCE-c from 3.3 ± 2.4 to 3.3 ± 2.6; CLCE-w: from 1.9 ± 2.2 to 2.1 2.5). Independent predictors of SCC at 12 months were baseline CLCE-c (ß = 0.54) and perceived stress (ß = 0.23) for content, and baseline CLCE-w (ß = 0.57) and depressive symptoms (ß = 0.23) for worry. CONCLUSIONS: Patients who report SCC at 3 months after stroke are likely to continue having these complaints at 1 year follow-up. Perceived stress and depressive symptoms additionally increase the likelihood of having SCC at 12 months, independent of SCC at 3 months poststroke. Rehabilitation programs that target reduction of stress and depression in the first months after stroke might reduce sustained SCC and improve well-being.

Psychological factors and subjective cognitive complaints after stroke: Beyond depression and anxiety.

Subjective Cognitive Complaints (SCC) are common after stroke and adversely affect quality of life. In the present study, we determined the associations of depression, anxiety, perceived stress and fatigue with post-stroke SCC, and whether these associations were independent of objective cognitive functioning, stroke characteristics and individual differences in personality traits and coping styles. Using a cross-sectional design, SCC and psychological measures were obtained in 208 patients (mean 3.3 ± 0.5 months after stroke; 65.9% men; mean age 64.9 ± 12.4 years). SCC were assessed using the Checklist for Cognitive and Emotional consequences following stroke (CLCE) inventory. Validated questionnaires were used to measure depression and anxiety (Hospital Anxiety and Depression Scale), perceived stress (Perceived Stress Scale), fatigue (Fatigue Assessment Scale), personality traits (Eysenck Personality Questionnaire Revised Short Scale) and coping style (Utrecht Coping List). Multivariate hierarchical linear regression analyses were used to adjust for covariates. Depression (ß = 0.35), anxiety (ß = 0.38), perceived stress (ß = 0.39), and fatigue (ß = 0.39) were associated with CLCE scores, independent of demographic, cognitive performance and stroke-related covariates. After including personality traits and coping styles in the model, independent associations with CLCE scores were found for fatigue (ß = 0.26, p = .003) and neuroticism (ß = 0.21, p = .05). Interventions aimed at improving psychological resilience and increasing energy levels might be a worthwhile addition to stroke rehabilitation programmes by reducing SCC and improving quality of life.

Illness identity in young adults with refractory epilepsy.

INTRODUCTION: Refractory epilepsy is an intrusive condition with important implications for daily functioning in emerging and young adulthood. The present study examined the degree to which refractory epilepsy is integrated in one's identity, and examined how such a sense of illness identity was related to health-related quality of life (HRQOL). METHODS: A total of 121 18- to 40-year-old patients with refractory epilepsy (56.2% women) completed self-report questionnaires assessing the four illness identity states of acceptance, enrichment, engulfment, and rejection (Illness Identity Questionnaire (IIQ)); HRQOL (Quality of Life in Epilepsy Inventory - 31); and seizure frequency and severity (Liverpool Seizure Severity Scale (LSSS)). Illness identity scores were compared with a sample of 191 patients with a nonneurological chronic disease (congenital heart disease). Hierarchical regression analyses were conducted to assess the predictive value of illness identity for HRQOL when simultaneously controlling for demographic and clinical features. RESULTS: Patients with refractory epilepsy scored higher on rejection and engulfment and lower on acceptance when compared with patients with congenital heart disease. Further, seizure severity and number of medication side-effects were positively related to engulfment and negatively to acceptance. Finally, when simultaneously controlling for various demographic and clinical variables, illness identity significantly predicted HRQOL (with engulfment being the strongest and most consistent predictor). CONCLUSION: The extent to which patients with refractory epilepsy succeed in integrating their illness into their identity may have important implications for HRQOL. Clinicians should be especially attentive for signs that patients feel engulfed by their epilepsy.

Prevalence and Profile of Poststroke Subjective Cognitive Complaints.

BACKGROUND: Subjective cognitive complaints (SCCs) are common after stroke, but detailed information about how SCCs differ between patients with stroke versus stroke-free individuals is not available. We evaluated the prevalence and profile of the 2 SCC components (content and worry) in patients 3 months after stroke versus controls using both a generic and a stroke-specific instrument. METHODS: Using a cross-sectional design, 142 patients were compared to 135 controls (matched at group level on age, sex, and estimate of premorbid intelligence quotient). SCC-content and SCC-worry were assessed using the Cognitive Failures Questionnaire (CFQ) and the Checklist of Cognitive and Emotional Consequences after stroke (CLCE-24). Univariate and multivariate linear (for continuous scores) and logistic (for dichotomous scores) regression analyses were used to explore differences between patients and controls on both instruments. RESULTS: Based on the CLCE, patients reported more SCC-content (standardized ß = .21, p.001) and SCC-worry (standardized ß = .18, p.02) than controls in multivariate analyses. Profiles indicated that stroke was associated in particular with SCC-content on the domains of memory, attention, executive functioning, expressive language, and with attention-related SCC-worry. In contrast, no group differences were found on SCC-content and SCC-worry assessed by the CFQ. CONCLUSIONS: The prevalence and profile of SCC-content and SCC-worry differ between patients and controls 3 months after stroke. The instrument used may, however, determine prevalence estimates. Stroke-specific inventories that differentiate between SCC-content and SCC-worry are preferable when attempting to determine SCC after stroke.

Quality of Life after Young Ischemic Stroke of Mild Severity Is Mainly Influenced by Psychological Factors.

BACKGROUND: Long-term prognosis in terms of quality of life (QoL) in young stroke patients is of importance because they usually have a long life expectancy and extensive daily life demands. We aimed at determining which medical and psychological factors influence the QoL in young stroke patients (<50 years), after long-term follow-up. METHODS: Young ischemic stroke patients admitted to the St. Elisabeth Hospital and the TweeSteden Hospital, Tilburg, the Netherlands, between 2000 and 2010 were included. One hundred seventy patients and 61 controls filled out the following questionnaires: (1) the Hospital Anxiety and Depression Scale, (2) the Fatigue Assessment Scale, and (3) the shortened World Health Organization Quality of Life scale. Using linear multiple regression analysis, we assessed the factors influencing QoL. RESULTS: QoL did not differ significantly between patients (median modified Rankin Scale score at follow-up, 0) and controls after a mean follow-up of 4.5 (standard deviation, 2.8) years. The presence of excessive fatigue was associated with lower scores on all domains of the QoL (P ≤ .003), but not for general health domain (P = .010). Similarly, depression was associated with worse QoL on the physical (P = .004) and psychological (P = .001) domains and anxiety with lower scores on the psychological (P < .001) QoL domain. No relationship was found between stroke-specific factors and QoL. CONCLUSIONS: Fatigue and to a lesser extent depression and anxiety affect the QoL in young adults after ischemic stroke of mild severity. Therefore, young stroke patients should be informed about, screened, and, if possible, treated for fatigue, depression, and anxiety.

Short-term cognitive effects after recovery from a delirium in a hospitalized elderly sample.

The aim of this study was to examine early cognitive performance after a delirium in elderly general hospital patients. Patients were divided into a delirium (n = 47) and a control (n = 25) group. One week before discharge and after delirium had cleared in the first group, all patients completed a neuropsychological test battery (The Cambridge Cognitive Examination-Revised [CAMCOG-R]). Group differences in cognitive performance were analyzed adjusting for differences in baseline sociodemographic and clinical variables. Adjusting for group differences in baseline variables, the delirium group performed significantly worse than the control group on CAMCOG-R; its subdomains language, praxis, and executive functioning; and on Mini Mental State Examination derived from CAMCOG-R. The occurrence of delirium in hospital thus detrimentally affects early cognitive performance.

Subjective cognitive complaints after stroke: a systematic review.

BACKGROUND: Most studies to date have assessed poststroke cognitive impairment objectively, whereas less attention is paid to subjective cognitive complaints (SCC). We, therefore, systematically searched the literature to summarize and evaluate the current knowledge about poststroke SCC. METHODS: Articles were included in this review if the study evaluated SCC in adult stroke survivors, and the publication was an original empirical article from which the full text was available. There were no year or language restrictions. RESULTS: Twenty-six studies were found on poststroke SCC. There is a huge heterogeneity among these studies with respect to stroke sample, SCC definitions, and instruments used, but they all showed that SCC are very common after stroke. Other main findings are that SCC tend to increase over time and that there is moderate agreement between patients and their proxies on prevalence and severity of patients' SCC. Furthermore, SCC are inconsistently associated with current depressive symptoms and objective cognitive performances, whereas they may predict future emotional and cognitive functioning. CONCLUSIONS: This review highlights that poststroke SCC are highly prevalent and that clinicians should take such complaints seriously. More research is, however, needed to gain further insight into poststroke SCC, to be able to accurately inform patients and relatives, and to develop adequate treatment programs. Based on the limitations of the studies to date, suggestions are made on how both future research and ultimately patient-centered care may be improved in stroke survivors.

The Effects of Neuropsychiatric Symptom Clusters in People with Dementia on Family Caregiver Burden.

Background: Neuropsychiatric symptoms are a robust risk factor for caregiver burden in family dementia caregivers. By grouping these symptoms, clinical interpretations regarding neuropsychiatric symptoms may facilitated because different groups of symptoms may require a different approach for intervention, thereby reducing caregiver burden. Objective: As clustering of neuropsychiatric symptoms could be clinically relevant, we aimed to explore the effects of these clusters on burden in family dementia caregivers. Methods: 152 family dementia caregivers were included. Caregiver burden was measured using the Ervaren Druk door Informele Zorg (EDIZ)/Self-Perceived Pressure from Informal Care, a Dutch questionnaire. Caregivers also reported the neuropsychiatric symptoms and functional impairments in daily activities of the people with dementia they cared for. Multiple regression analyses were used in this cross-sectional study. Results: Adjusted for functional impairments and sociodemographic variables, neuropsychiatric symptoms were associated with more caregiver burden (p < 0.001). However, this association did not differ between the three neuropsychiatric symptom clusters (p = 0.745). Conclusions: Neuropsychiatric symptoms were associated with more family caregiver burden, but no conclusive evidence was found that this association differed for the three clusters. Clustering of neuropsychiatric symptoms is, however, worth exploring further in future studies with more participants. If specific links are found, these could be targeted in clinical practice in order to prevent, reduce and/or postpone caregiver burden.

Can subjective cognitive complaints at three months post stroke predict alteration in information processing speed during the first year?

Cognitive impairment, particularly slowing of information processing speed (IPS), is prevalent after stroke. However, the link between subjective cognitive complaints (SCC) and cognitive deficit remains unclear. This study evaluated the link between SCC at three months post stroke and deficit as well as objective alterations in IPS in the first year post stroke. Patients (N = 200) and healthy controls (N = 105) took part in the COMPlaints After Stroke study (COMPAS). SCC, IPS and depression were evaluated at 3 months, 1 and 2 years post stroke. The Reliable Change Index was used to assess change in IPS in the first year post. Approximately one out of three patients showed deficit in IPS irrespective of time post stroke, while a change in IPS (N = 117) over time was relatively uncommon. SCC at three months post stroke did not predict change in IPS between three months and one year post stroke, where depressive symptoms did show a link. Cross sectional data showed a deficit in IPS in a substantial number of stroke patients irrespective of the point in time. Longitudinal data revealed a further decline in a small subgroup in the first year post stroke, which was not predicted by SCC at three months post stroke. The findings show that, irrespective of time post stroke and even when stroke is relatively mild, impairment in IPS is prevalent, but cannot be predicted by the complaints patients express. The link with depressive symptoms needs more exploration.

Influence of Sense of Competence, Empathy and Relationship Quality on Burden in Dementia Caregivers: A 15 Months Longitudinal Study.

Objectives: The aim is to explore the trajectory of caregiver burden and how this relates to caregiver and contextual factors in community-dwelling dyads. Methods: At baseline, 201 family caregivers were included. The multidimensional construct of family caregiver burden and the effects of sense of competence, empathy, and quality of the relationship on this burden were assessed over 15 months using semi-structured interviews and questionnaires. Results: We found an increase of burden linked to disruptions in the caregiver's own usual activities (p = 0.002) and physical health complaints (p = 0.001). Caregivers with a high sense of competence experienced lower caregiver burden during the entire caregiving process (p < 0.001). Discussion: Healthcare professionals should alert family caregivers to the importance of taking care of themselves as early as possible in their new caregiver role. Caregiving is demanding and could negatively influence their own activities and physical health.

Stimulus material selection for the Dutch famous faces test for older adults.

Worldwide, approximately 22% of all individuals aged 50 years and older are currently estimated to fall somewhere on the Alzheimer's disease (AD) continuum, which can be roughly divided into preclinical AD, mild cognitive impairment (MCI), and AD dementia. While episodic memory loss (among other aspects) is typically required for a diagnosis of AD dementia, MCI is said to have occurred when cognitive impairment (including memory loss) is worse than expected for the person's age but not enough to be classified as dementia. On the other hand, preclinical AD can currently only be detected using biomarkers; clinical symptoms are not apparent using traditional neuropsychological tests. The main aim of the current paper was to explore the possibility of a test which could distinguish preclinical AD from normal aging. Recent scientific evidence suggests that the Famous Faces Test (FFT) could differentiate preclinical AD from normal aging up to 5 years before a clinical AD diagnosis. Problematic with existing FFTs is the selection of stimulus material. Faces famous in a specific country and a specific decade might not be equally famous for individuals in another country or indeed for people of different ages. The current article describes how famous faces were systematically selected and chosen for the Dutch older (60+) population using five steps. The goal was to design and develop short versions of the FFT for Dutch older adults of equivalent mean difficulty. In future work, these nine parallel versions will be necessary for (a) cross-sectional comparison as well as subsequent longitudinal assessment of cognitively normal and clinical groups and (b) creating personalized norms for the normal aged controls that could be used to compare performance within individuals with clinical diagnoses. The field needs a simple, cognitive test which can distinguish the earliest stages of the dementia continuum from normal aging.

A Systematic Review on the Potential Acceleration of Neurocognitive Aging in Older Cancer Survivors.

As survival rates increase, more emphasis has gone to possible cognitive sequelae in older cancer patients, which could be explained by accelerated brain aging. In this review, we provide a complete overview of studies investigating neuroimaging, neurocognitive, and neurodegenerative disorders in older cancer survivors (>65 years), based on three databases (Pubmed, Web of Science and Medline). Ninety-six studies were included. Evidence was found for functional and structural brain changes (frontal regions, basal ganglia, gray and white matter), compared to healthy controls. Cognitive decline was mainly found in memory functioning. Anti-hormonal treatments were repeatedly associated with cognitive decline (tamoxifen) and sometimes with an increased risk of Alzheimer's disease (androgen deprivation therapy). Chemotherapy was inconsistently associated with later development of cognitive changes or dementia. Radiotherapy was not associated with cognition in patients with non-central nervous system cancer but can play a role in patients with central nervous system cancer, while neurosurgery seemed to improve their cognition in the short-term. Individual risk factors included cancer subtypes (e.g., brain cancer, hormone-related cancers), treatment (e.g., anti-hormonal therapy, chemotherapy, cranial radiation), genetic predisposition (e.g., APOE, COMT, BDNF), age, comorbidities (e.g., frailty, cognitive reserve), and psychological (e.g., depression, (post-traumatic) distress, sleep, fatigue) and social factors (e.g., loneliness, limited caregiver support, low SES). More research on accelerated aging is required to guide intervention studies.

Preclinical Alzheimer's dementia: a useful concept or another dead end?

The term, preclinical dementia, was introduced in 2011 when new guidelines for the diagnosis of Alzheimer's dementia (AD) were published. In the intervening 11 years, many studies have appeared in the literature focusing on this early stage. A search conducted in English on Google Scholar on 06.23.2022 using the term "preclinical (Alzheimer's) dementia" produced 121, 000 results. However, the label is arguably more relevant for research purposes, and it is possible that the knowledge gained may lead to a cure for AD. The term has not been widely adopted by clinical practitioners. Furthermore, it is still not possible to predict who, after a diagnosis of preclinical dementia, will go on to develop AD, and if so, what the risk factors (modifiable and non-modifiable) might be. This Review/Theoretical article will focus on preclinical Alzheimer's dementia (hereafter called preclinical AD). We outline how preclinical AD is currently defined, explain how it is diagnosed and explore why this is problematic at a number of different levels. We also ask the question: Is the concept 'preclinical AD' useful in clinical practice or is it just another dead end in the Holy Grail to find a treatment for AD? Specific recommendations for research and clinical practice are provided.

Cognitive functioning in the acute phase poststroke: a predictor of discharge destination?

Cognitive dysfunction occurs in more than half of stroke survivors and can have far-reaching consequences for functioning in daily life. Assessment of cognitive function can play a major role in determining the appropriate discharge destination after a hospital stay. The present study aimed to determine the feasibility of cognitive screening in the acute phase poststroke and to investigate whether this cognitive screening can accurately predict discharge destination to either a dependent or an independent living situation. A total of 287 patients with a first-ever cerebral stroke consecutively admitted to a stroke unit of a general hospital were eligible for the study. All patients underwent neuropsychological screening, consisting of the Mini-Mental State Examination (MMSE), Cognitive Screening Test (CST), and Clock-Drawing Test, within 7 days poststroke. Screening was feasible in 73.2% of the patients. Logistic regression analysis showed that the Barthel Index (BI) score (ie, ability to perform activities of daily living) could predict the discharge destination with 47% explained variance when age and BI score were taken into account. Adding the 3 cognitive tests to the model with age and BI improved the explained variance substantially (53%), with a significant contribution of BI and CST. Cognitive screening in the acute phase poststroke appeared to be feasible and capable of supporting the decision of whether to discharge a patient to home or to a dependent living situation. Functional status improved the predictive value of the model; the MMSE was not suitable for prediction. A comprehensive set of various predictors, including cognition, is recommended to support discharge planning.
