Book Synopsis Dementia diagnostics in primary care by : Anna Segernäs Kvitting
Download or read book Dementia diagnostics in primary care written by Anna Segernäs Kvitting and published by Linköping University Electronic Press. This book was released on 2019-09-20 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background Age is the greatest risk factor for developing dementia and the total number of people aged 60 years and above is expected to more than double globally from 2013 to 2050 (1). Primary health care (PHC) is important for basic diagnostic evaluations. Objective test measurements have been shown to be more reliable than a patient's subjective memory complaints in dementia assessments (2). However, several studies indicate the low use of objective cognitive screening tools in dementia diagnostics in PHC (3). Some general practitioners (GPs) do not perceive today’s cognitive instruments as helpful in the diagnostic process and administration problems have been reported in PHC (4, 5). The overall aim of this thesis was to investigate the accuracy of several cognitive tests used in dementia assessments in PHC, especially among older patients: A Quick Test of Cognitive Speed (AQT), Cognistat and Cognitive Assessment Battery (CAB). The normative values of the Mini Mental Status Examination (MMSE) in the oldest old was also studied. Methods The studies included in this thesis are from two different study populations. Studies I, II and IV. Patients with and without cognitive symptoms were recruited from four primary health care centres in Sweden between 2007 and 2009.Study III. The Elderly in Linköping Screening Assessment (ELSA 85) cohort-population examined people born in 1922 in the municipality of Linköping, Sweden. Results Study I. Results showed that AQT is a usable test for dementia diagnosis in PHC. Sensitivity for AQT is superior to the Clock Drawing Test (CDT), equivalent to MMSE and the combination MMSE and CDT. The AUC for AQT was 0.773, valued good enough. Study II. Overall, the results for Cognistat in this study are superior to MMSE and CDT, also in combination. Cognistat is promising for improved dementia diagnosis in PHC with a quick and easily administered multi-domain test for dementia assessments. Study III. This study presents valuable information about normative MMSE data for the oldest patients. Results, suggest using the 25th percentile in MMSE of 25 to 26 points, and indicate that MMSE 26 is as a reasonable cut-off for cognitive decline and further medical evaluation in older persons aged from 85 to 93 years. Study IV. In summary, the additive value of the CAB test in dementia investigations in PHC is not obvious. In addition to questionable accuracy, the test is quite time consuming and normative values are scarce. By introducing the numerical sum (CABsum) the accuracy was increased. Conclusion In conclusion, objective cognitive tests are an important part of dementia diagnosis in PHC and there is a need for improved instruments and norm-values. From our results, several cognitive quick tests are usable in PHC - MMSE, AQT and Cognistat - but they have some disadvantages. MMSE 26 is a reasonable cut-off for cognitive decline in the oldest patients 85 to 93 years from a well-educated population with quite good socioeconomic. There is a great interest in finding short and better multi-domain instruments but the additive value of CAB in dementia investigations in PHC is questionable.

Book Synopsis Diagnosis of Dementia and Cognitive Impairment by : Andrew J. Larner
Download or read book Diagnosis of Dementia and Cognitive Impairment written by Andrew J. Larner and published by MDPI. This book was released on 2019-12-10 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this special issue of Diagnostics, expert contributors have produced up-to-date research studies and reviews on various topics related to the diagnosis of dementia and cognitive impairment. The methods of the assessments discussed extend from simple neurological signs, which may be elicited in the clinical encounter, through cognitive screening instruments, to sophisticated analyses of neuroimaging and cerebrospinal fluid biomarkers of disease. It is hoped that these various methods may facilitate earlier diagnosis of dementia and its subtypes, and provide differential diagnosis of depression and functional cognitive disorders, as a prelude to meaningful interventions.

Book Synopsis Dementia and Memory by : Lars-Göran Nilsson
Download or read book Dementia and Memory written by Lars-Göran Nilsson and published by Psychology Press. This book was released on 2013-11-20 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: A negative effect of the ageing population is that more individuals are experiencing cognitive decline and some form of neurodegenerative disease. With the number of people experiencing dementia likely to double in the next 20 years, this change in society presents one of greatest challenges facing public health personnel in the 21st century. The aim of this volume is to describe research that is in progress, and the major findings that have been obtained in the scientific study of dementia. The chapters in the first section of the book focus upon early signs of dementia, and consider several approaches to finding early cognitive signs and biological markers of dementia. The second section considers whether dementia is inevitable for people who become very old, and features chapters on risk factors and proactive influences, cognitive reserve and intervention. Each chapter in the final section describes phenomena which are related to differences in function between memory systems, including anterograde memory in fronto-temporal dementia, and the role semantic memory and semantic cognition may play in developing an understanding of the development of the degenerative processes in dementia. With contributions from world-class researchers in this area, the volume offers a concise overview of key findings in recent research on dementia and memory. It will be of great interest to researchers and advanced students of cognitive psychology, and to those working in related fields, such as gerontology, rehabilitation sciences, and allied health.
