- Background: Some studies have suggested a lower incidence of cancer in patients with dementia. We studied this further for 18 cancer types in population-based registers. Methods: In 19,756 cases and in 147,324 age- and sex-matched controls a diagnosis of dementia was studied 9-45 months prior to the diagnosis of cancer. Results: Overall a diagnosis of dementia was significantly less common among the cancer cases (risk ratio, RR = 0.60; 95% CI = 0.52-0.69). Conclusion: The study confirms previous findings that patients with dementia have a lower risk of cancer. Because the effect was seen for all tumour types and especially for patients older than 70 years and since the deficit was more pronounced for patients with tumours situated within the body, the data suggest that malignancies are underdiagnosed for persons with dementia.

- <i>Background/Aims:</i> To explore the presenting and early symptoms of dementia with Lewy bodies (DLB). <i>Method:</i> Patients with mild dementia fulfilling diagnostic criteria for DLB (n = 61) and Alzheimer’s disease (AD) (n = 109) were recruited from outpatient dementia clinics in western Norway. At diagnosis, caregivers were asked which symptom had been the presenting symptom of dementia. <i>Results:</i> Caregivers reported that memory impairment was the most common presenting symptom in DLB (57%), followed by visual hallucinations (44%), depression (34%), problem solving difficulties (33%), gait problems (28%), and tremor/stiffness (25%). In contrast, 99% of AD carers reported impaired memory as a presenting symptom, whereas visual hallucinations were a presenting symptom in 3% of the AD cases. <i>Conclusion:</i> DLB should be suspected in predementia cases with visual hallucinations.

- Aims: To examine the degree of agreement between self-and informant ratings of personality in relation to cognitive function in patients with mild cognitive impairment (MCI), subjective cognitive impairment (SCI) and healthy controls (HC). Methods: Thirty-two patients and informants with MCI, 23 with SCI and 22 HC completed the Swedish universities Scales of Personality (SSP). Correlations and incongruence between self-and informant ratings were calculated. The Mini Mental State Examination (MMSE) was used to assess cognitive function. Results: The correlations between self-and and informant ratings were fair-to-moderate on a majority of SSP scales and significant in 44%. The incongruence between patients and informants was significantly larger in MCI than in HC across SSP scales. There was a significant negative correlation between the incongruence index and the MMSE for all subjects. Conclusions: Self-informant agreement on ratings of patients' personality was reasonable. Incongruence between patients and their informants was associated with MCI but not SCI or HC. Disagreement between patients and informants indicates cognitive impairment. Copyright (C) 2012 S.

- Background/Aims: Motor impairment is an important aspect of cognitive decline in older adults. It has been suggested that complex motor control is affected earlier than gross motor control. The aims were to investigate if complex hand motor function was more affected than gross motor function in cognitively impaired older subjects, and to present reference values. Methods: Alternating forearm movements and grip strength were studied in 301 cases, 419 intermediates and 1,207 controls, aged 60-93 years, controlling for demographic, health-related and functional factors and comorbidity. Global cognitive function was assessed by the Mini-Mental State Examination, and episodic memory by 3-word delayed recall. Grip strength was assessed by the Grippit(R). The frequency of alternating movements during 10 s was registered electronically. Results: Alternating movements but not grip strength was associated with cognitive impairment (right: p = 0.006; left: p = 0.022). The mean alternating movements for the 70-year-old male cases compared to the controls were 2.3 versus 2.5 Hz for the right, and 2.2 versus 2.4 Hz for the left arm (p < 0.05), and for the 60-year-old women 2.0 versus 2.3 Hz for the right arm (p < 0.05). Conclusion: Complex but not gross hand motor function is associated with early cognitive impairment.

- <b><i>Aims:</i></b> To evaluate the serum levels of interleukin (IL)-18, IL-23 and IL-17 in Chinese patients with Alzheimer's disease (AD), and explore correlations between the three cytokines and relevant parameters. <b><i>Methods:</i></b> Serum concentrations of IL-18, IL-23 and IL-17 were measured by ELISA for 53 AD patients and 53 sex- and age-matched healthy controls in a community of elderly individuals in a Shanghai suburb. <b><i>Results:</i></b> Serum concentrations of IL-18, IL-23 and IL-17 were significantly higher in AD patients than controls. The serum level of IL-23 was observed to be significantly higher (p = 0.049) in female AD patients than male AD patients. In addition, a significantly inverse correlation was found between IL-18 and MMSE score (r<sub>s</sub> = -0.356, p = 0.011) for all AD patients. <b><i>Conclusion:</i></b> Elevated IL-18, IL-23 and IL-17 levels are observed in AD patients and differences may exist between males and females. Besides, IL-18 may correlate with the severity of AD.

Does Vascular Burden Contribute to the Progression of Mild Cognitive Impairment to Dementia?
- 2012
-
Ingår i: Dementia and Geriatric Cognitive Disorders. - : S. Karger AG. - 1420-8008 .- 1421-9824. ; 34:3-4, s. 235-243

- Aims: To investigate the contribution of vascular risk factors (VRFs), vascular diseases (VDs) and white matter lesions (WMLs) to the progression of mild cognitive impairment (MCI) to dementia and Alzheimer’s disease (AD). Methods: Two hundred forty-five consecutive subjects with MCI (age 74.09 ± 6.92 years) were followed for an average of 2.4 years. The Hachinski Ischemic Score and the Framingham Stroke Risk Profile were used to summarize VRFs and VDs. WMLs were graded using the Age-Related White Matter Changes Scale. Results: One hundred twenty-nine (52.6%) out of 245 subjects at risk converted to dementia, including 87 cases of AD. When hypertension occurred in MCI with deep WMLs, a 1.8-fold increased risk of dementia was observed (95% CI = 1.0–3.4). When deep WMLs occurred in MCI with high scores (≥4) on the Hachinski scale, a 3.5-fold (95% CI = 1.6–7.4) and 3.8-fold (95% CI = 1.2–11.5) risk of progression to dementia and AD was observed, respectively. Analogously, the joint effect of WMLs and high scores (≥14) on the Framingham scale nearly doubled the risk of dementia (hazard ratio = 1.9, 95% CI = 1.1–3.3). Conclusions: Accelerated progression of MCI to dementia and AD is to be expected when VRFs and VDs occur together with WMLs.

- Background/Aims: Psychosocial intervention has shown positive effects on the caregivers' burden and satisfaction. The aims of this study were to describe the cost and cost-effectiveness of such an intervention. Methods: We analyzed resource use and costs of formal care for 308 persons with dementia and their caregivers' health-related quality of life (HRQoL). Results: The costs of home help services were lower in the subgroup of spouse caregivers in the intervention group and the cost of nursing home placement was lower in the intervention group. While the person with dementia lived at home, caregivers in the intervention group reported a higher HRQoL (p < 0.01). After the person with dementia had moved to a nursing home, spouses in the control group had a lower HRQoL (p < 0.001). Conclusion: The result can be interpreted as a positive effect of the intervention focusing on the identified specific needs of the family caregivers. © 2013 S. Karger AG, Basel.

- Background/Aims: To identify prodromal Alzheimer's disease (AD) subjects using a data-driven approach to determine cognitive profiles in mild cognitive impairment (MCI). Methods: A total of 881 MCI subjects were recruited from 20 memory clinics and followed for up to 5 years. Outcome measures included cognitive variables, conversion to AD, and biomarkers (e. g. CSF, and MRI markers). Two hierarchical cluster analyses (HCA) were performed to identify clusters of subjects with distinct cognitive profiles. The first HCA included all subjects with complete cognitive data, whereas the second one selected subjects with very mild MCI (MMSE >= 28). ANOVAs and ANCOVAs were computed to examine whether the clusters differed with regard to conversion to AD, and to AD-specific biomarkers. Results: The HCAs identified 4-cluster solutions that best reflected the sample structure. One cluster (aMCIsingle) had a significantly higher conversion rate (19%), compared to subjective cognitive impairment (SCI, p < 0.0001), and non-amnestic MCI (naMCI, p = 0.012). This cluster was the only one showing a significantly different biomarker profile (A beta(42), t-tau, APOE epsilon 4, and medial temporal atrophy), compared to SCI or naMCI. Conclusion: In subjects with mild MCI, the single-domain amnestic MCI profile was associated with the highest risk of conversion, even if memory impairment did not necessarily cross specific cut-off points. A cognitive profile characterized by isolated memory deficits may be sufficient to warrant applying prevention strategies in MCI, whether or not memory performance lies below specific z-scores. This is supported by our preliminary biomarker analyses. However, further analyses with bigger samples are needed to corroborate these findings. Copyright (C) 2013 S. Karger AG, Basel
