- Objectives: Mild cognitive impairment (MCI) is a state of mildly impaired cognitive functioning but with an intact capability of performing basic daily activities. Few studies have targeted personal narratives from persons living with MCI, the major focus in this study is directed to methods for better predictions of the likelihood for conversion to dementia. This study directly explores experiences among individuals who have lived with MCI over seven years without converting to dementia. Methods: Seventeen individuals, who had been diagnosed with MCI across four occasions over a seven-year period at a memory clinic, were interviewed at a single occasion about their experiences of living with MCI, life events, stress, coping, psychosocial resources, and lifestyle behaviors. Results: Thematic analysis of the transcripts of the interviews resulted in themes revolving around the life situation and events related to the first visit at the memory clinic, coping with lower cognitive capacity with the aim of enhancing quality of life, and worries about dementia and further cognitive deteriorations. Conclusion: The participants' experiences of living with MCI indicate that issues and changes in life situations such as long-term stress, retirement, loss of relatives, perceived heritability of dementia, needs to be understood in the context of the individual's understanding and interpretation of their everyday cognitive functioning. Also, supportive long-term contacts with the specialist care unit were vital for creating a personal understanding of MCI. Addressing the intra-personal dynamics of cognitive functioning in the boundary between normal and pathological cognitive aging can also improve diagnostic accuracy.

- Cognitive impairment is one of the most pronounced symptoms reported by patients with stress-related mental health problems. Impairments related to executive function and to some extent speed and attention are therefore common in patients with stress-related burnout/exhaustion. In this paper we present a follow-up of cognitive performance in patients with stress-related exhaustion several years after they initially sought medical care. Thirty patients and 27 healthy controls, mean age 49 years (SD 6.5) and 55 years (SD 6.7) respectively, were included, all of whom had undergone baseline measurements of neuropsychological functioning. The mean follow-up time was three years. Half of the patients still reported mental health problems at follow-up and over time no major changes in cognitive performance were noted. The patients still performed significantly poorer than controls with regard to cognitive functions, mainly related to speed, attention and memory function. Long-lasting impairment of cognitive functions related to speed, attention and memory function noted in patients with stress-related exhaustion should be acknowledged and taken into consideration during treatment and when discussing a return to work. Follow-up periods longer than three years are needed to explore the persistence of the cognitive impairment. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd

- The purpose of this study was to construct a Swedish version of the National Adult Reading Test (NART-SWE), a test for assessment of premorbid IQ, and to investigate its validity and reliability on healthy controls and patients with mild Alzheimer's disease. As Swedish pronunciation rules are fixed, NART-SWE was constructed using loan words. NART-SWE has satisfactory psychometric properties: Inter-rater and retest reliability as well as internal consistency are very high. The NART-SWE demonstrates face validity. In addition, high correlation with IQ was obtained. A significant model emerged when using NART-SWE to predict IQ. Furthermore, no significant differences were observed when comparing performance for healthy controls' with that of patients with Alzheimer's disease on NART-SWE. It does appear that reading of irregular words is intact in mild Alzheimer's disease.

Boston Naming Test automatic credits inflate scores of nonaphasic mild dementia patients
- 2016
-

Tidskriftsartikel (refereegranskat)abstract
- Introduction: The Boston Naming Test (BNT), a 60-item test of confrontation naming, may be administered either from Item 1 or Item 30, depending on assumptions of performance. If the BNT is administered from Item 30, 29 automatic credits are given for preceding items, allowing identical norms for either administration. We aimed to compare effects of automatic credits. Method: We compared effects of automatic credits in the Gothenburg Mild Cognitive Impairment Study, first between normal controls (n = 23) and patients (n = 259), and then between the same patients grouped by stage of impairment: subjective cognitive impairment (SCI, n = 75), mild cognitive impairment (MCI, n = 117), or mild dementia (n = 67). Results: Automatic credits added to all groups. Both administrations from Item 1 and those from Item 30 discriminated between controls (n = 23) and all patients (n = 259), as well as between the above stages of impairment. However, neither administration discriminated between normal controls and SCI patients. When earned scores were compared, with scores counted from Item 30 plus 29 automatic credits, mild dementia patients on average received a 3.4-credit boost. This equals 82% of the standard deviation of Tallberg's Swedish norms [Brain and Language, 94(1), 19-31 (2005)] or 117% of our normal controls' standard deviation. Conclusions: In our homogenous material, administration of BNT from Item 30 distinguished between stages of deterioration as well as administration from Item 1. In line with recent literature, we also find BNT results skewed. Thus, for clinical accuracy, we recommend use of cumulative percentages, careful consideration of education and demographic factors, and, most importantly, never to mix forms of administrations with and without automatic credits. While BNT automatic credits diminish accuracy on all levels, they inflate scores significantly for nonaphasic mild dementia patients.

- BACKGROUND: The epsilon4 allele of the apolipoprotein E (APOE) gene and low levels of cerebrospinal fluid (CSF) amyloid beta-proteins 42 (Abeta) have previously been associated with increased risk of cognitive decline in old age. In this study we examine the interaction of these markers with episodic memory in a sample identified as having mild cognitive impairment (MCI). METHODS: The sample (N = 149) was drawn from the Gothenburg MCI study and measured according to three free recall tests on three occasions spanning over four years. Second-order Latent Curve Models (LCM) were fitted to the data. RESULTS: Analyses accounting for age, gender, education, APOE, Abeta42, and interaction between APOE and Abeta42 revealed that the epsilon4 allele was significantly associated with level of memory performance in the presence of low Abeta42 values (< or = 452 ng/L). Associations between memory performance and Abeta42 were significant among the epsilon4 carriers but not among the non-carriers. The Abeta42 marker was, however, significantly associated with changes in memory over the study time period in the total sample. CONCLUSION: The findings support the hypothesis of an interactive effect of APOE and Abeta42 for memory decline in MCI patients.

Tidskriftsartikel (refereegranskat)abstract
- The challenges of today's society call for more knowledge about how to maintain all aspects of cognitive health, such as speed/attention, memory/learning, visuospatial ability, language, executive capacity and social cognition during the life course.Medical advances have improved treatments of numerous diseases, but the cognitive implications have not been sufficiently addressed. Disability induced by cognitive dysfunction is also a major issue in groups of patients not suffering from Alzheimer's disease or related disorders. Recent studies indicate that several negative lifestyle factors can contribute to the development of cognitive impairment, but intervention and prevention strategies have not been implemented. Disability due to cognitive failure among the workforce has become a major challenge. Globally, the changing aging pyramid results in increased prevalence of cognitive disorders, and the diversity of cultures influences the expression, manifestation and consequences of cognitive dysfunction.Major tasks in the field of cognitive medicine are basic neuroscience research to uncover diverse disease mechanisms, determinations of the prevalence of cognitive dysfunction, health-economical evaluations, and intervention studies. Raising awareness for cognitive medicine as a clinical topic would also highlight the importance of specialized health care units for an integrative approach to the treatment of cognitive dysfunctions.

- Objectives We examined cognitive functions before and in acute phase of stroke studying frequency and profile of cognitive impairment and relationships between cognitive status.MethodsSeventy-four patients with early phase after stroke and 49 healthy controls were included and examined using the Mini-Mental State Examination (MMSE) and a battery of neuropsychological tests. Cognitive status before stroke-onset was investigated using Cognitive Impairment Questionnaire.ResultsCognitive impairments were present in 96% of patients after stroke onset using the battery of neuropsychological tests and in 39% of patients using the MMSE, but in only 9% of controls. Seventy-six percent exhibited reduced executive function and 75% reduced psychomotor tempo. Cognitive dysfunction was present in 52% before stroke onset without any impact on the frequency of impairment in the various cognitive areas in early phase after stroke.ConclusionsCognitive impairment is frequent before the onset of stroke among older people and may partially explain the very high frequency of cognitive impairment observed after stroke onset.
