The mental health status of asylum seekers in middle- to high-income countries: a synthesis of current global evidence.

INTRODUCTION: The last 5 years have witnessed a significant increase in the number of people fleeing their countries of origin and seeking refuge in host countries. By the end of 2018, there were 3.5 million asylum seekers awaiting outcomes on their applications, the majority of whom were hosted by middle- to high-income countries. This review aimed to identify and synthesize current knowledge regarding the mental health status of asylum seekers in middle- to high-income countries. SOURCES OF DATA: A search was conducted across various databases for research literature published within the last 5 years (2014-2019). The final review and synthesis included 25 articles. AREAS OF AGREEMENT: Findings highlighted significant differences in the mental health status of asylum seekers compared to those with refugee status and permanent residence. AREAS OF CONTROVERSY: Guidelines from the World Health Organization and the United Nations High Commissioner for Refugees emphasize the need to understand and address mental health issues. Instead, there have been policy changes in many host countries regarding asylum applications, and the associated effects of these changes have been shown to negatively impact mental health. GROWING POINTS: The synthesized findings from the present review provide information regarding the current mental health status of asylum seekers hosted by middle- to high-income countries. Areas of intervention and resource allocation were also identified. AREAS TIMELY FOR DEVELOPING RESEARCH: Future research should consider the impact of large-scale, low-cost interventions to support the mental health of those seeking asylum.

Delirium in Elderly Patients:Frequency and Precipitants in a Tertiary Hospital Setting.

OBJECTIVE: There is paucity of information on delirium in sub-Saharan Africa (SSA) particularly in the older persons (>60 years of age), leaving questions about the burden of the disease in an environment with lower health care standards. In this article, we set out to determine the frequency, precipitants and symptomatology of delirium in elderly patients admitted into medical wards in a teaching hospital in South-West Nigeria. METHODS: This was a descriptive study involving a pre-planned sample of one hundred and fifty patients aged 60 years and over, assessed for cognitive impairment and delirium using the previously validated IDEA cognitive screen, and the Confusion Assessment Method (CAM) respectively. Diagnosis of delirium was made using the CAM and DSM-IV criteria. RESULTS: Delirium was diagnosed in 32 patients giving a frequency of 21.3% (95%CI: 14.7-30.0%). Patients with delirium were significantly older (p<0.05). A quarter of the patients had dementia. Hypertension was a notable co-morbid condition. All the patients had altered sleep wake cycle, inattention, disorientation, and altered consciousness. Neurological diseases were the most common precipitant. There was a good agreement between the DSM-IV and CAM diagnoses. CONCLUSION: Delirium is common in hospitalised elderly patients particularly those with neurological diseases. Co-morbidities like hypertension, dementia, and depression should be looked for in delirious elderly patients.

Parietal Involvement in Constructional Apraxia as Measured Using the Pentagon Copying Task.

Deficits in copying ("constructional apraxia") is generally defined as a multifaceted deficit. The exact neural correlates of the different types of copying errors are unknown. To assess whether the different categories of errors on the pentagon drawing relate to different neural correlates, we examined the pentagon drawings of the MMSE in persons with subjective cognitive complaints, mild cognitive impairment, or early dementia due to Alzheimer's disease. We adopted a qualitative scoring method for the pentagon copy test (QSPT) which categorizes different possible errors in copying rather than the dichotomous categories "correct" or "incorrect." We correlated (regional) gray matter volumes with performance on the different categories of the QSPT. Results showed that the total score of the QSPT was specifically associated with parietal gray matter volume and not with frontal, temporal, and occipital gray matter volume. A more fine-grained analysis of the errors reveals that the intersection score and the number of angles share their underlying neural correlates and are associated with specific subregions of the parietal cortex. These results are in line with the idea that constructional apraxia can be attributed to the failure to integrate visual information correctly from one fixation to the next, a process called spatial remapping.

Diagnostic Value of Time-Constrained Naming Test in Mild Cognitive Impairment.

BACKGROUND: Naming difficulties have recently garnered more interest in elderly individuals with mild cognitive impairment (MCI). We anticipate that naming tests with the consideration of response time can provide more informative and distinct neuropsychological profiles of individuals with MCI. METHODS: Naming tests were administered to 76 elderly individuals with MCI and 149 healthy elderly (HE). We analyzed the impact of MCI on naming performance and occurrence of "delayed" response. We also validated the predictive power of naming tests with a time-constrained scoring system. RESULTS: MCI participants performed poorer on the noun naming test than HE participants (p = 0.014). MCI was significantly associated with the occurrence of "delayed" response on the noun (odds ratio [OR] = 3.57; 95% confidence interval [CI] = 1.78-7.17) and verb naming tests (OR = 4.66; 95% CI = 2.07-10.46). The time-constrained naming scores were significantly better able to distinguish the MCI from the HE group than the conventional spontaneous naming score on both the noun (p < 0.001) and verb (p = 0.002) naming tests. CONCLUSIONS: Our findings broaden the knowledge related to the naming ability in individuals with MCI, with respect to the response time. We also confirmed the validity of the naming tests by applying the "delayed" responses as supplementary assessments in the diagnosis of MCI.

The cognitive profile of ALS: a systematic review and meta-analysis update.

Cognitive impairment is present in approximately 30% of patients with amyotrophic lateral sclerosis (ALS) and, especially when severe, has a negative impact on survival and caregiver burden. Our 2010 meta-analysis of the cognitive profile of ALS showed impairment of fluency, executive function, language and memory. However, the limited number of studies resulted in large confidence intervals. To obtain a more valid assessment, we updated the meta-analysis and included methodological improvements (controlled data extraction, risk of bias analysis and effect size calculation of individual neuropsychological tests). Embase, Medline and PsycInfo were searched for neuropsychological studies of non-demented patients with ALS and age-matched and education-matched healthy controls. Neuropsychological tests were categorised in 13 cognitive domains and effect sizes (Hedges' g) were calculated for each domain and for individual tests administered in ≥5 studies. Subgroup analyses were performed to assess the influence of clinical and demographic variables. Forty-four studies were included comprising 1287 patients and 1130 healthy controls. All cognitive domains, except visuoperceptive functions, showed significant effect sizes compared to controls. Cognitive domains without bias due to motor impairment showed medium effect sizes (95% CI): fluency (0.56 (0.43 to 0.70)), language (0.56 (0.40 to 0.72)), social cognition (0.55 (0.34 to 0.76)), or small effect sizes: delayed verbal memory 0.47 (0.27 to 0.68)) and executive functions (0.41 (0.27 to 0.55)). Individual neuropsychological tests showed diverging effect sizes, which could be explained by bias due to motor impairment. Subgroup analyses showed no influence of bulbar disease onset and depression and anxiety on the cognitive outcomes. The cognitive profile of ALS consists of deficits in fluency, language, social cognition, executive functions and verbal memory. Social cognition is a new cognitive domain with a relatively large effect size, highlighting the overlap between ALS and frontotemporal dementia. The diverging effect sizes for individual neuropsychological tests show the importance of correction for motor impairment in patients with ALS. These findings have implications for bedside testing, the design of cognitive screening measures and full neuropsychological examinations.

Effect of CPAP therapy on C-reactive protein and cognitive impairment in patients with obstructive sleep apnea hypopnea syndrome.

PURPOSE: Obstructive sleep apnea hypopnea syndrome (OSAHS) is associated with neurocognitive impairment. We examined the role of the systemic inflammatory response, measured by high-sensitivity C-reactive protein (hsCRP) assay, and the effect of CPAP treatment on hsCRP and cognitive impairment in patients with OSAHS. METHODS: Eligible subjects (n = 178) were categorized into two groups: absent or mild OSAHS, and moderate to severe OSAHS. First, the Montreal Cognitive Assessment (MoCA) and serum hsCRP concentration were measured. Then, the moderate to severe OSAHS group was further divided into a conservative treatment subgroup (n = 68) and a CPAP subgroup (n = 68). After 6 months of treatment, MoCA scores and hsCRP concentrations were re-measured in the moderate to severe group. RESULTS: Compared with the absent or mild OSAHS group, hsCRP concentration was higher (1.00 ± 1.28 mg/L versus 2.71 ± 1.8, p < 0.001) and MoCA scores were significantly lower (27.4 ± 1.4 versus 26.3 ± 2.0, p < 0.001) in the moderate to severe group. After adjustment for age, education, body mass index, and neck circumference, hsCRP and MoCA scores correlated with parameters of overnight hypoxia. hsCRP and the proportion of time spent with blood oxygen saturation < 90 % (T90) predicted MoCA score. hsCRP and MoCA score improved, and the subdomains of the MoCA were partially improved, in the CPAP treatment subgroup. In conservatively managed patients, hsCRP concentration increased, and there was no improvement in neurocognitive dysfunction, with the memory subdomain significantly worse. CONCLUSIONS: hsCRP may play a role in neurocognitive dysfunction in OSAHS. Long-term CPAP treatment could normalize the serum hsCRP concentration and partially reverse cognitive dysfunction in OSAHS.

Can we forget the Mini-Mental State Examination? A systematic review of the validity of cognitive screening instruments within one month after stroke.

OBJECTIVE: To review systematically studies investigating the convergent, criterion, and predictive validity of multi-domain cognitive screening instruments in the first four weeks after stroke. DATA SOURCES: Electronic databases (Pubmed, PsycINFO, CINAHL, Embase) were searched until June 2014. REVIEW METHODS: Studies concerning screening for cognitive dysfunction in stroke patients using multi-domain instruments, within four weeks postinfarct or haemorrhagic stroke, using tests taking no longer than one hour. Convergent, criterion, and predictive validity were examined. RESULTS: A total of 51 studies investigating 16 cognitive screening instruments were identified. None of the instruments covered all of the most affected cognitive domains. Only one study investigated the convergent validity of a multi-domain test during the (sub)acute phase after stroke. A total of 15 studies examined the criterion validity of cognitive measurements during the acute phase after stroke. The Montreal Cognitive Assessment and Higher Cortical Function Deficit Test had good criterion validity. A total of 24 studies examined the predictive ability of multi-domain cognitive instruments applied in the acute phase after stroke. The Cognistat, Montreal Cognitive Assessment, and Functional Independence Measure-cognitive showed good predictive validity. The Mini-Mental State Examination is the most widely used cognitive screening instrument, but shows insufficient criterion validity. CONCLUSION: None of the existing instruments fulfils all criteria. The Montreal Cognitive Assessment is the best candidate at present, provided items measuring speed of information processing are added, and further studies investigating the optimal cut-offs are conducted.

[Pain measurement in cognitively impaired patients with the Doloshort scale]. / Schmerzmessung bei kognitiv beeinträchtigten Patienten mit der Doloshort-Skala.

BACKGROUND: Until recently the measurement of pain in cognitively impaired patients represented a neglected field in the diagnostics and treatment of pain. Investigations indicate a prevalence of pain in nursing home residents of between 45 % and 80 %. MATERIAL AND METHODS: This study investigated the reliability of the German translation of the Doloshort scale and compared it with the visual analog scale (VS). The aim of this study was to determine the practical applicability of this scale in the clinical routine and to calculate the intrarater reliability (retest) and interrater reliability. RESULTS: The interrater and intrarater reliability of the Doloshort scale was between 0.949 and 0.970. There was a highly significant correlation between the values of the Doloshort scale and the VAS. CONCLUSION: The Doloshort scale is a well suited measurement instrument for the evaluation of pain in cognitively impaired patients. Because of the short form only simple instructions are necessary and it has a high acceptance with users.

Comparisons of clinical symptoms in biomarker-confirmed Alzheimer's disease, dementia with Lewy bodies, and frontotemporal dementia patients in a local memory clinic.

BACKGROUND: There has been no previous Chinese study that differentiated the clinical symptoms among biomarker-confirmed Alzheimer's disease (AD), dementia with Lewy bodies (DLB) and frontotemporal dementia (FTD). The objective of this study was to compare the cognitive, behavioural, and neuropsychiatric symptoms in biomarker-confirmed AD, DLB, and FTD patients. METHODS: We recruited 30 patients (14 AD, 7 DLB, 9 FTD) who presented to the memory clinic at Queen Mary Hospital from 1 January 2007 to 31 December 2013. AD was diagnosed according to the National Institution of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association criteria with cerebrospinal fluid biomarkers (tau, phosphorylated tau, and amyloid ß-42) fulfilling locally determined cut-off values for AD. DLB was diagnosed based on the McKeith diagnostic criteria. The behavioural variant of FTD was diagnosed based on the revised diagnostic criteria proposed by the International bvFTD Criteria Consortium, and language variant FTD was diagnosed based on the latest published criteria. In addition, patients with DLB and FTD had typical imaging features on single-photon emission computed tomography or (18) fludeoxyglucose-positron emission tomography, either with or without Pittsburgh Compound B imaging, which supported their diagnoses. Data on patient characteristics including demographics, presenting clinical features, Mini-Mental State Examination, clinical dementia ratings, and neuropsychiatry inventory scores were collected. RESULTS: There were no differences in age, education level, dementia severity, and duration of symptoms before presentation among the three subgroups of patients. All patients had amnesia symptoms, which were not statistically significant. Apraxia was most common in AD. While 83% of the patients were affected by behavioural and neuropsychiatric symptoms of dementia, behavioural disinhibition and decline in executive function were most common in FTD patients. Recurrent hallucinations, fluctuation of consciousness, parkinsonism, and rapid eye movement sleep behaviour disorder were most common in DLB. CONCLUSION: Memory impairment and apathy are not useful discriminative symptoms in diagnosing AD, DLB, and FTD. Apraxia favours AD. Hallucinations, particularly well-formed visual hallucinations, favour DLB. Overall, behavioural and neuropsychiatric symptoms of dementia symptoms are common among the three groups of dementia patients.

Test the reliability of doubly robust estimation with missing response data.

In statistical inference, one has to make sure that the underlying regression model is correctly specified otherwise the resulting estimation may be biased. Model checking is an important method to detect any departure of the regression model from the true one. Missing data are a ubiquitous problem in social and medical studies. If the underlying regression model is correctly specified, recent researches show great popularity of the doubly robust (DR) estimates method for handling missing data because of its robustness to the misspecification of either the missing data model or the conditional mean model, that is, the model for the conditional expectation of true regression model conditioning on the observed quantities. However, little work has been devoted to the goodness of fit test for DR estimates method. In this article, we propose a testing method to assess the reliability of the estimator derived from the DR estimating equation with possibly missing response and always observed auxiliary variables. Numerical studies demonstrate that the proposed test can control type I errors well. Furthermore the proposed method can detect departures from model assumptions in the marginal mean model of interest powerfully. A real dementia data set is used to illustrate the method for the diagnosis of model misspecification in the problem of missing response with an always observed auxiliary variable for cross-sectional data.

Acceptance of and attitudes towards Alzheimer's disease screening in elderly German adults.

BACKGROUND: Considering the discussion on implementing routine dementia screening in Germany, the objective of the current study was to validate the German version of the Perceptions Regarding Investigational Screening for Memory in Primary Care (PRISM-PC) questionnaire and to determine the acceptance of Alzheimer's disease screening in elderly German adults. METHODS: The German version of the PRISM-PC was administered to a subsample of participants who attended the Berlin Aging Study II (n = 506). The questionnaire was validated by exploratory as well as confirmatory factor analysis. RESULTS: Regarding acceptance of Alzheimer's disease screening (Section B) a single factor structure fitted best. In terms of attitudes regarding Alzheimer's disease (Section D), a hierarchical factor structure was modeled with the higher-order factor "Harms" covering the domains "Family Burden," "Dependence," "Emotional Suffering," "Stigma," and "Medical Care" on the one hand and the domain "Future Planning" on the other hand. Internal consistency of the different scales reached from α = 0.67 to α = 0.94. Overall, 71.2% of the participants indicated that they wanted to be screened for Alzheimer's disease on a regular basis. CONCLUSIONS: This study suggests that acceptance can reliably be assessed with the section "Acceptance of Alzheimer's disease screenings" of the German PRISM-PC questionnaire. Furthermore, the majority of elderly German adults would like to be screened for Alzheimer's disease regularly, which might be an effective starting point in order to implement routine dementia screenings. As the sample is a convenience sample of (relatively) healthy older adults, generalizability of these results is limited.

The prevalence and recognition rate of delirium in hospitalized elderly patients in Turkey.

OBJECTIVE: Delirium is frequently observed, but generally under recognized in elderly hospitalized patients. The aims of this study were to determine the prevalence of delirium in elderly patients hospitalized at a university hospital, and to determine the recognition rate by hospital staff during hospitalization. METHODS: The study included 108 consecutive patients aged ≥ 65 years that were hospitalized in the medical and surgical inpatient departments at Baskent University Hospital, Ankara, Turkey. All the patients were evaluated using the Mini Mental State Examination (MMSE) upon admission and Confusion Assessment Method (CAM) on a daily basis during hospitalization. Written documents and consultation requests from psychiatry and/or neurology departments were reviewed for recognition of delirium by hospital staff. RESULTS: Among the 108 patients in the study, delirium was noted in 18 (16.7%) during their hospital stay. Consultation from psychiatry or neurology departments was requested for 5 of the 18 patients, only 1 with a delirium diagnosis, indicating that 17 of the cases (94.4%) were not recognized by their primary physicians. CONCLUSIONS: The delirium non-recognition rate in elderly hospitalized patients was very high. We think that hospital staff must be trained to recognize the symptoms of delirium and identify high-risk patients.

Processing speed in the aging process: screening criteria for the Spanish Quick Test of Cognitive Speed.

A Quick Test of Cognitive Speed was administered to 357 participants without cognitive impairment, aged 18 to 85 years, to explore the effects of age on processing speed variables in Spanish speakers and to provide normative data for the test adapted to this population. Results were consistent with previous findings: correlations between age and naming times were high and statistically significant. Linear regression indicated that cognitive processing speed on this test slows 2 to 4 sec. per decade, depending on the task. Normalized data were provided. The findings concur with several studies that have linked age-cognitive impairment with slowing processing speed. This study attempted to assess the importance of this relation, as information processing speed could be considered a measure of cognitive impairment in everyday clinical screening evaluations.

The heterogeneity of cognitive symptoms in Parkinson's disease: a meta-analysis.

Several studies have reported heterogeneity in cognitive symptoms associated with specific characteristics of patients with Parkinson's disease (PD). Indeed, researchers have characterised subtypes of patients suffering from PD according to various criteria. Those most frequently used are the type of predominant motor symptoms (tremors or non-tremor symptoms), age at onset and presence of depression. Some characteristics, like the predominant motor subtypes, as well as the presence of depression, are more widely used to categorise cognitive differences between patients. The goal of this study was to analyse the impact of the type of predominant motor symptoms and depression on cognition in PD. A meta-analysis of 27 studies (from 1989 to 2012) was carried out to calculate the average effect size of these factors on the most often used cognitive test during those past years to evaluate cognitive skills, the Mini-Mental State Examination. The studies analysed showed significant mean weighted effect sizes on cognition for the type of motor symptoms (d=0.42; 95% CI 0.30 to 0.54) and for depression (d=0.52; 95% CI 0.38 to 0.66). These results suggested that PD participants with non-tremor predominant motor symptoms or with depression had more or more severe cognitive impairments. Identification of different subtypes in PD is important for a better understanding of the cognitive symptoms associated with this disease. Better knowing the impact of different features of PD subgroups could help to design more appropriate treatments for patients with PD.

The association between social stress and global cognitive function in a population-based study: the European Prospective Investigation into Cancer (EPIC)-Norfolk study.

BACKGROUND: Stress is thought to exert both positive and negative effects on cognition, but the precise cognitive effects of social stress and individuals' response to stress remain unclear. We aimed to investigate the association between different measures of social stress and cognitive function in a middle- to older-aged population using data from the European Prospective Investigation into Cancer (EPIC)-Norfolk study. METHOD: Participants completed a comprehensive assessment of lifetime social adversity between 1993 and 1997 and the short form of the Mini Mental State Examination (SF-MMSE), an assessment of global cognitive function, during the third health check between 2004 and 2011 (a median of 10.5 years later). A low MMSE score was defined as a score in the bottom quartile (20-26). RESULTS: Completed MMSE scores and stress measures were available for 5129 participants aged 48-90 years. Participants who reported that their lives had been more stressful over the previous 10 years were significantly more likely to have low MMSE scores [odds ratio (OR) 1.14, 95% confidence interval (CI) 1.04-1.24 per unit increase in perceived stress], independently of sociodemographic factors, physical and emotional health. The effects were restricted to the highest level of stress and the association was stronger among participants with a lower educational level. Adaptation following life event experiences also seemed to be associated with MMSE scores after adjusting for sociodemographic factors, but the association was attenuated with further adjustment. CONCLUSIONS: In this generally high-functioning population, individuals' interpretations and responses to stressful events, rather than the events themselves, were associated with cognitive function.

Mini-Mental Status Examination as predictors of mortality in the elderly.

OBJECTIVE: Because the number of elderly is increasing worldwide, cognitive dysfunction becomes important health care issue. This study investigated the association between cognitive dysfunction and mortality in the elderly. METHOD: Data were analyzed from a longitudinal mortality follow-up study of 2712 Korean elderly aged 60 and over, examined in 2002 with complete data followed an average 6.03 years. Measurements included socio-demographic and clinical factors and Mini-Mental State Examination (MMSE). MMSE was categorized into groups with no, mild, or moderate cognitive dysfunction, and the subscores of MMSE domains were categorized into no dysfunction or dysfunction. The Cox proportional hazards models were conducted to examine the association between MMSE score and mortality, after adjusting for age, gender, education and other socio-demographic factors. RESULTS: Death during follow-up occurred in 318 subjects. The mortality risk was significantly associated with the elderly with mild cognitive dysfunction [hazard ratio (HR) = 1.93] and with moderate cognitive dysfunction (HR = 2.66). 'Orientation-to-time' (HR = 1.39) and 'Attention' (HR = 1.48) domains of MMSE were independently associated with mortality. CONCLUSION: This study showed that cognitive dysfunction independently predicted mortality in the elderly. Cognitive dysfunction should be considered part of identifying the elderly at high risk for mortality.

Limits of the Epworth Sleepiness Scale in older adults.

PURPOSE: Excessive daytime sleepiness (EDS) in older adults is associated with obstructive sleep apnea, falls, reduced quality of life, and mortality. The Epworth Sleepiness Scale (ESS) is widely used to assess sleepiness. However, EDS assessment with the ESS may not be accurate in older adults. We aimed to (1) describe the responsiveness of nondemented older subjects to the ESS and (2) compare the self-report ESS scores to those of close relatives (CR) proxy and identify factors influencing any discrepancies between them. METHODS: This is a cross-sectional observational study including 104 independently living nondemented older subjects with daytime sleepiness complaints and 104 nondemented CRs. Cognitive tests (Mini-Mental State Examination) and the ESS were completed separately by subjects and CRs to assess the subject's daytime sleepiness. RESULTS: Almost 60 % of subjects and CRs were not able to answer at least one question on the ESS. Despite the fact that all subjects complained of EDS, only 24 % of them had an abnormal ESS score (>10). Subjects rated their sleepiness lower (7.10 ± 4.31) than their CR proxy did (9.70 ± 5.14) (p < 0.0001). In multivariate analysis, an increase in age and a decrease in cognitive status of the subjects appeared related to the difference in ESS between subject and CR. CONCLUSIONS: The majority of older adults were not able to answer all of the ESS items. The ESS may underestimate sleepiness severity in older subjects. Despite EDS complaints in all subjects, only one quarter of them had a pathological ESS score.

Effects of education on very mild dementia among Chinese people in Hong Kong: potential mediators in the Cantonese Mini-Mental State Examination tasks.

BACKGROUND: In Hong Kong, older Chinese adults generally have a low level of education. This study examined the effect of education on very mild Alzheimer's disease (AD), as quantified by Clinical Dementia Rating (CDR) scale (CDR 0.5 versus 0), in a Chinese community. The Cantonese version of the Mini-Mental State Examination (C-MMSE) was used to estimate cognitive abilities that were related to the level of education, and that in turn serve as protective factors for AD. METHODS: A total of 788 community-dwelling older adults (383 CDR 0 and 405 CDR 0.5) were recruited in this cross-sectional study, which was derived from a population-based prevalence project. The participants' number of years of education and C-MMSE scores were used to predict their CDR scores using logistic regression and the mediation effects of C-MMSE scores were analyzed. RESULTS: Consistent with previous studies, the chance of being rated as having very mild AD increased with age, but decreased with years of education, among the older adult community of Hong Kong. The effect of education on very mild dementia was weakened substantially when C-MMSE scores were included as mediating variables. CONCLUSIONS: The findings indicate that the protective effects of education on dementia were mediated by an enhancement of older adults' performance on some C-MMSE items, including attention and orientation to time and place.

Positive effects of Ska game practice on cognitive function among older adults.

BACKGROUND: Ska is a traditional board game in Thailand that involves high levels of cognition, planning, and decisionmaking. There have been no previous studies on the benefits of the Ska game as a cognitive function aid for older adults. OBJECTIVE: To examine the effects of Ska game practice on improving cognitive functioning among older adults. MATERIAL AND METHOD: Forty older adults living in the municipality of Phetchabun province, volunteered to take part in the present study. They were randomly selected and arranged into two intervention groups, an experiment and a control group (20 participants each group; 10 females and 10 males). Each group was repeatedly trained as planned for at least 50 minutes per day, three sessions per week for the continuous duration of 16 weeks. The cognitive function measured in term of memory, Verbal Pair Association I and II (VPA I; VPA II), Visual Reproduction I and II (VR I; VR II), the attention used of Trail Making Test part A (TMT-A), and the executive function used by means of the Wisconsin Card Sorting Test (WCST). The examination was done by a clinical psychologist and a medical technologist using neurotransmitter to measure Acetylcholinesterase (AChE) activity, before and after the intervention. The independent variables were measured with t-test to compare the mean scores of two different groups and between males and females of the Ska group. The level of significance considered was p < 0.05. RESULTS: The findings revealed that those who joined the Ska group reported statistically significant better scores of cognitive function in memory, attention, executive function from VPA I, VPA II, VR I, VR II, TMT-A, and WCST compared to those who were in the control group (p < 0.05). However, there was no significant difference of AChE activity between the Ska and the control group (p > 0.05). In addition, there was no significant difference mean in cognitive function between male and female Ska group (p > or = 0.05). CONCLUSION: Finding shows that the Ska game could enhance the cognitive functioning in terms of memory, attention, and executive function in older adults.

Discrepancy between subjective and objective assessments of wandering behaviours in dementia as measured by the Algase Wandering Scale and the Integrated Circuit tag monitoring system.

AIM: Although wandering is one of the major research focuses of the behavioural psychological symptoms of dementia, assessment of wandering has mostly relied on caregiver-administered questionnaires. The purpose of this study was to compare staff-administered Algase Wandering Scale outcomes with objective temporal and spatial movement indicators obtained from the Integrated Circuit (IC) tag monitoring system. METHODS: Patients with dementia were recruited from a dementia care unit in Osaka, Japan in 2007. Primary nurses administered the Algase Wandering Scale, and the temporal and spatial movements of the subjects were monitored by the IC tag. Written informed consent was obtained from each subject's proxies. RESULTS: Nurses' assessments of wandering were in agreement with the IC tag outcomes only during the day shift. Spatial movements assessed by the staff did not reflect those measured by the IC tag. CONCLUSION: This objective measurement of wandering showed the limitations in the assessment of spatial and temporal movement by the staff.
