Diagnosis Of Dementia

Abstract Background Currently, many patients suffering from dementia do not have a diagnosis when admitted to geriatric hospitals. This is the case despite an increased risk of complications affecting the length of stay and outcome. Unfortunately, many dementia screening tests cannot be used on geriatric inpatients, who are often bedridden. Therefore, we aimed at evaluating the diagnostic accuracy of a small battery of bedside tasks that require minimal vision and fine motor skills in patients with suspected dementia. Methods In this prospective study, the Bamberg Dementia Screening Test (BDST) was administered to a consecutive series of 1295 patients referred for neuropsychological testing. The diagnosis of dementia was confirmed in 1159 and excluded in 136 patients. Sensitivity and specificity for the first subtest (ultra-short form), the first two subtests (short form), and the total score of the BDST were obtained via receiver operating characteristic curves and compared with the sensitivity and specificity values of the Mini-Mental Status Examination (MMSE). Results The overall diagnostic quality of the BDST was superior to the MMSE for mild Alzheimer’s dementia (sensitivity and specificity = .94 (95% CI .92 to .96) and .82 (95% CI .75 to .88) vs. .79 (95% CI .76 to .83) and .88 (95% CI .82 to .93)) as well as for other subtypes of mild dementia (sensitivity and specificity = .91 (95% CI .88 to .94) and .82 (95% CI .75 to .88) vs. .72 (95% CI .67 to .76) and .88 (95% CI .82 to .93)). Even the short form of the BDST was comparable to the MMSE regarding sensitivity and specificity. For moderate dementia, it was possible to identify dementia cases with sufficient and excellent diagnostic quality by using the ultra-short and the short form. Conclusions The BDST is able to detect dementia in geriatric hospital settings. If the adaptive algorithm is used, administration time can be reduced to less than 2 min in most cases. Because no test materials have to be exchanged, this test is particularly suitable for infectious environments where contact between the examiner and the person being tested should be minimized.

Diagnosis Of Dementia

The Mini-Mental State Exam (MMSE) is a brief cognitive test that assesses several cognitive domains, such as orientation, attention, concentration, memory, language, and constructional abilities. While the MMSE was found to be valid and reliable in the diagnosis of moderate dementia, its sensitivity and specificity for the diagnosis of mild dementia has been rarely examined. We assessed the specificity and sensitivity of the MMSE in a consecutive series of 44 patients with mild dementia, and a group of age-comparable normal controls. While the specificity of the MMSE for the diagnosis of mild dementia was very high (100%), the sensitivity was only 55% [20 of the 44 patients with mild dementia had an MMSE score in the normal range (≥26 points)]. On the other hand, the assessment with both the Buschke Selective Reminding and the Boston Naming tests discriminated mild Alzheimer's disease patients with normal MMSE scores from controls with a sensitivity and specificity of 64%. In conclusion, the assessment with verbal memory and naming tasks provided a significantly more sensitive measure of early dementia than the MMSE.

Diagnosis Of Dementia

Purpose – People with Down's syndrome are at increased risk of developing early onset Alzheimer's disease. It has been recommended that all adults with Down's syndrome receive baseline neuropsychological testing for dementia. In certain areas prospective screening of people with Down's syndrome takes place to ensure the early diagnosis of the condition. However, little has been published on the value of this type of screening. The purpose of this paper is to report on a prospective screening programme and asks whether the programme is effective in identifying dementia-related changes in people with Down's syndrome and whether the current screening intervals are appropriate. Design/methodology/approach – All adults with Down's syndrome in Plymouth (UK) are identified and offered a comprehensive test battery at baseline at the age of 20 and then have testing biennially from 40 to 50 and annually after 50. All individuals diagnosed with dementia between 2001 and 2013 were identified and their case notes examined. The symptoms at the time of diagnosis were identified and whether these symptoms had been identified through the screening programme or by other routes were recorded. Prevalence data and age at diagnosis were also recorded. Findings – In total, 26 people were diagnosed with dementia during the study period. Of these, the diagnosis of dementia followed concerns being identified during the routine screening programme in 54 per cent of cases. In the younger age group (age 40-49) 63 per cent of people were identified through the screening programme. At the time of diagnosis a mean of 5.5 areas of concern were in evidence. Research limitations/implications – Limited by small sample size, however service development not original research. Implications for the use of prospective dementia screening in people with Down's syndrome. Practical implications – Implications for how services choose to run their Down's syndrome and dementia screening programmes, including the frequency of screening. Originality/value – The paper adds to a growing evidence base around the value of prospective dementia screening in people with Down's syndrome. It is also one of a few studies exploring the frequency of screening. Additionally, it adds further data about prevalence of dementia in people with Down's syndrome.

Background: Shortly after the introduction of the first licensed vaccine against dengue fever (Dengvaxia), a serious outcome was attributed to the vaccine: vaccinated individuals without a previous dengue infection were at increased risk of developing severe dengue if subsequently infected by a heterologous serotype. In response, the World Health Organization recommended vaccination in regions where the seroprevalence of dengue is at least 50% and, ideally, greater than 70%. Hence, accurate estimates of regional seroprevalence are crucial for both population vaccination strategies and test-then-vaccinate decisions at the individual level. Currently, estimates of seroprevalence are based on surveys, using screening tests for previous dengue exposure. These estimates must consider the sensitivity and specificity of the tests, which depend on identification of those who have been exposed, ostensibly through a test, regarded as the gold standard. There is, however, no easily accessible gold standard test for dengue. Methods: We propose an approach to estimate the seroprevalence of dengue that does not require a gold standard test by modeling: (i) the uncertainty in the sensitivity and specificity, and (ii) the uncertainty in the “true” disease prevalence. Results: Through simulations, we demonstrate the effect of these extra sources of uncertainty on post-test estimates of dengue seroprevalence. Our simulations show, for example, that in a population of 1 million it is possible to overestimate or underestimate the number who are truly seropositive by as much as 76,000. Conclusions: Current estimates can substantially overestimate or underestimate the true probability of previous exposure when these extra sources of variability are not accounted for.

Introduction Studies show Aboriginal and Torres Strait Islander people are at increased risk of dementia. Whilst there have been several studies evaluating the use of telehealth for improving Aboriginal and Torres Strait Islander health outcomes, and studies validating telehealth dementia screening tools for the wider community, none have addressed the pressing need for culturally appropriate telehealth dementia screening for this at-risk population. The aim of the study was to examine the utility of using a culturally appropriate dementia screening tool (KICA-screen) in a telehealth setting. Methods A prospective field trial was used to compare administration of the short version of the Kimberley Indigenous Cognitive Assessment (KICA-screen) face-to-face and via telehealth. A total of 33 medically stable Aboriginal and Torres Strait Islander inpatients/outpatients participated. The stability of the KICA-screen scores, administered face-to-face and via telehealth, for each participant was measured. Results The two test delivery methods showed not only good correlation (Pearson’s r = 0.851; p < 0.01) but good agreement (intraclass correlation coefficient = 0.85; p < 0.01). Discussion Results of the assessment showed that KICA-screen can be reliably administered via videoconference and resulted in comparable scores to face-to-face testing in the majority of cases. The telehealth process was acceptable to participants, who were able to understand the process and complete the full screen via telehealth conditions.

Cerebral palsy (CP) is a disorder characterized by abnormal tone, posture and movement. The incidence of CP is 2–4 per 1,000 live births in the world. Prematurityand low birth weight are important risk factors for CP; however, multiple other factors have been associated with an increased risk for CP, including maternal infections and diseases, and abnormal birth process. In most cases of CP the initial injury to the brain occurs during early fetal brain development, later a brain area that is injured cannot function properly in the future. CP is classified clinically based on the predominant motor syndrome—spastic hemiplegia, spastic diplegia, spastic quadriplegia, ataxic and dyskinetic cerebral palsies. The diagnosis of CPis based on a combination of clinical history, use of standardized neuromotor assessment and findings on magnetic resonance imaging (MRI). If there is a suspicionof genetic or inborn metabolic disorders, screening tests should be provided additionally. Because CP is associated with multiple associated and secondary medical conditions, its management requires a multidisciplinary team approach

Abstract Introduction Insomnia is a common and impairing late effect experienced by many young adult cancer survivors (YACS). Although routine evaluation of sleep disorders in cancer survivors is recommended, lack of consensus on appropriate screening measures contributes to under-identification and under-treatment of these disorders in YACS. As screening measures are ideally as brief as possible while maintaining validity, we sought to validate the recently published three-item Insomnia Severity Index Short-Form (ISI-SF) in YACS. Methods 250 YACS completed the ISI and the Structured Clinical Interview for the DSM-5 (SCID-5). The ISI-SF was created by summing three ISI items: distress (item #6), interference (item #7), and satisfaction (item #4). In receiver operating characteristic (ROC) analyses, area under the curve (AUC) was calculated to compare discrimination on the ISI-SF to two criteria: the full-scale ISI using a cutoff of ≥8 recently validated in this sample, and the SCID-5 insomnia module. Consistent with previous research, we specified a priori that a cut-off score on the ISI-SF with sensitivity ≥.85 and specificity ≥.75 would be acceptable. Results The ISI-SF had excellent discrimination when compared to the full-scale ISI (AUC = .97) and a cut-off score of ≥4 met criteria with a sensitivity of 97% and specificity of 86%. The ISI-SF had good discrimination when compared to the SCID-5 (AUC = .88), but none of the cut-off scores met a priori criteria for sensitivity and specificity. A cut-off score of ≥4 came closest with a sensitivity of 94% and specificity of 70%. Conclusion Although the ISI-SF did not meet sensitivity and specificity criteria for a stand-alone screening measure when compared to a diagnostic interview, it demonstrated utility as the first step in a two-step screening procedure. Specifically, the high sensitivity of the ≥4 ISI-F cut-off score is well-suited to accurately screening out YACS who do not need insomnia services; as a second screen, the SCID-5 insomnia module could be administered only to those elevated on the ISI-SF in order to identify false positives cases before making referrals for insomnia specialists.

Abstract Aims Pulse pressure (PP) is a well-known risk factor for cardiovascular disease. However, the association between the PP and dementia is not well identified. This study aimed to determine the effect of PP on the risk of dementia development in different age subgroups using a longitudinal, population-based, and stroke-free cohort from the general population. Methods The association of PP with the development of incident dementia was assessed from January 1, 2005, to December 31, 2013, in 433,154 participants without a history of dementia or stroke from the Korea National Health Insurance Service-Health Screening cohort. The diagnosis of dementia was defined using the 10th revision of the International Classification of Disease codes. Results The mean age of the cohort was 55.7±9.2 years, 45.7% were women. Hypertension was 23.6%. The mean systolic and diastolic blood pressure of the entire cohort were 125.9±16.6 and 78.4±10.7 mmHg, respectively. Mean PP was 47.5±10.9 mmHg. In the middle-age group (40 to 50 year-old), increasing of 10 mmHg of PP was associated with incident dementia after adjusting mean blood pressure and clinical variables with a hazard ratio (HR) of 1.21 (95% confidence interval [CI]: 1.19–1.23, p&lt;0.001). The association was still significant even after censoring for stroke (HR: 1.16, 95% CI: 1.08–1.22, p&lt;0.001). In the older population, elevation of PP was not associated with dementia development (HR: 0.98, 95% CI: 0.95–1.01, p=0.247) Conclusion PP was associated with increased risk of dementia only in middle-aged population beyond that of mean arterial pressure.

AbstractThis cohort study aimed to compare the incidence of type 2 diabetes in adults with depression-related weight gain, depression-related weight loss, depression with no weight change, and no depression. The study sample included 59,315 community-dwelling adults in Ontario, Canada. Depression-related weight change in the past 12 months was measured using the Composite International Diagnostic Interview—Short Form. Participants were followed for up to 20 years using administrative health data. Cox proportional hazards models compared the incidence of type 2 diabetes in adults with depression-related weight change and in adults with no depression. Adults with depression-related weight gain had an increased risk of type 2 diabetes compared to adults no depression (HR 1.70, 95% CI 1.32–2.20), adults with depression-related weight loss (HR 1.62, 95% CI 1.09–2.42), and adults with depression with no weight change (HR 1.39, 95% CI 1.03–1.86). Adults with depression with no weight change also had an increased risk of type 2 diabetes compared to those with no depression (HR 1.23, 95% CI 1.04–1.45). Associations were stronger among women and persisted after adjusting for attained overweight and obesity. Identifying symptoms of weight change in depression may aid in identifying adults at higher risk of type 2 diabetes and in developing tailored prevention strategies.

Memory Complaints

It is not easy to differentiate patients with mild cognitive impairment (MCI) from subjective memory complainers (SMC). Assessments with screening cognitive tools are essential, particularly in primary care where most patients are seen. The objective of this study was to evaluate the diagnostic accuracy of screening cognitive tests and to propose a score derived from screening tests. Elderly subjects with memory complaints were evaluated using the Mini Mental State Examination (MMSE) and the Brief Cognitive Battery (BCB). We added two delayed recalls in the MMSE (a delayed recall and a late-delayed recall, LDR), and also a phonemic fluency test of letter P fluency (LPF). A score was created based on these tests. The diagnoses were made on the basis of clinical consensus and neuropsychological testing. Receiver operating characteristic curve analyses were used to determine area under the curve (AUC), the sensitivity and specificity for each test separately and for the final proposed score. MMSE, LDR, LPF and delayed recall of BCB scores reach statistically significant differences between groups (P=0.000, 0.03, 0.001 and 0.01, respectively). Sensitivity, specificity and AUC were MMSE: 64%, 79% and 0.75 (cut off &lt;29); LDR: 56%, 62% and 0.62 (cut off &lt;3); LPF: 71%, 71% and 0.71 (cut off &lt;14); delayed recall of BCB: 56%, 82% and 0.68 (cut off &lt;9). The proposed score reached a sensitivity of 88% and 76% and specificity of 62% and 75% for cut off over 1 and over 2, respectively. AUC were 0.81. In conclusion, a score created from screening tests is capable of discriminating MCI from SMC with moderate to good accurancy.

Abstract Introduction Osteoporosis and sarcopenia often co-exist (osteo-sarcopenia) and both are associated with increased risk of falls and fractures. Early identification and treatment of sarcopenia among older people with fragility arm fractures could prevent further fractures. This study evaluated the feasibility of assessing sarcopenia in a fracture clinic. Methods People aged 65+ years with arm fracture attending fracture clinics in one acute trust were recruited. Sarcopenia was assessed using gait speed, grip strength with unfractured arm (hand dynamometer using appropriate cut off adjusted for age and gender), skeletal muscle mass index SMI (Bioimpedance BIA), SARC-F questionnaire, the European Working Group on Sarcopenia in Older People (EWGSOP) I and II criteria. The sensitivity and specificity of each measure was calculated against the EWGSOP II criteria as the standard reference. Results 100 patients (Mean age 75 years±7.2; 80 female) were recruited. Sarcopenia was identified among 4% (EWGSOP I), 5% (SMI), 13% (EWGSOP II), 16% (gait speed test), 18% (SARC-F) and 39% (grip strength) and was more prevalent among men. SARC-F had the best sensitivity and specificity (100% and 96% respectively) when compared to the EWGSOP II criteria. Sensitivity and specificity for the remaining measures were respectively (100%, 71%) for grip strength, (75%, 94%) for gait speed, (25%, 97%) with SMI and (25%, 99%) for EWGSOP I. Time needed to complete the assessments was 1–2 minutes for gait speed, grip strength and SARC-F; five minutes for BIA test, and nine minutes when EWGSOP I and II criteria were applied. Data were complete for grip strength and SARC-F. Missing data was reported among 2% for gait speed, 8% for BIA test, 8% for EWGSOP II and 10% for EWGSOP I. Conclusion It was feasible to assess sarcopenia in fracture clinics and SARC-F was a quick, simple and sensitive tool suitable for routine use.
