- Aims. To follow weight changes in patients with moderate and severe dementia and analyse how these changes related to biological and psychological parameters after staff education and support in integrity promoting care. A further aim was to describe meal environment and routines relative to the intervention.Background. Weight loss in patients with dementia and in particular Alzheimer's disease is common. The aetiology appears multifactorial with the meal environment and a decreased independence while eating among the factors.Method. Over a three-month intervention period, an integrity-promoting care training programme was conducted with the staff of a long-term ward. Alzheimer's disease patients, 18 from an intervention ward and 15 from a control ward were included and possible effects were evaluated. Weighing was conducted at the start and after completion of the intervention. Weight changes were analysed in relation to psychological and biochemical parameters. In addition, the staff wrote diaries about, for example changes made in the environment and in their work.Results. The most prominent difference observed was weight increases in 13 of 18 patients compared with two of 15 patients in the control ward. No weight changes were related to the type of dementia. The individual weight changes correlated significantly to changes in the intellectual functions. Relationships between weight change, increased motor function and increased appetite were non-significant. There was no significant relationship between weight changes and changes in biochemical parameters. According to the staff, increased contact with the patients and a more pleasant atmosphere resulted when the meal environment and routines were changed.Relevance to clinical practice. Weight gain in patients with moderate and severe dementia was achieved by adjusting the meal environment to the individual's needs. Staff education was profitable, as increased competence seemed to promote individually adapted feeding situations. Ensuring good meal situations need to be given high priority.

- Background/Aims: Clinical short-term trails have shown positive effects of donepezil treatment in patients with Alzheimer's disease. The outcome of continuous long-term treatment in the routine clinical settings remains to be investigated. Methods: The Swedish Alzheimer Treatment Study (SATS) is a descriptive, prospective, longitudinal, multicentre study. Four hundred and thirty-five outpatients with the clinical diagnosis of Alzheimer's disease, received treatment with donepezil. Patients were assessed with Mini-Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog), global rating (CIBIC) and Instrumental Activities of Daily Living (IADL) at baseline and every 6 months for a total period of 3 years. Results: The mean MMSE change from baseline was positive for more than 6 months and in subgroups of patients for 12 months. After 3 years of treatment the mean change from baseline in MMSE-score was 3.8 points (95% CI, 3.0-4.7) and the ADAS-cog rise was 8.2 points (95% CI, 6.4-10.1). This is better than expected in untreated historical cohorts, and better than the ADAS-cog rise calculated by the Stern equation (15.6 points, 95% CI, 14.5-16.6). After 3 years with 38% of the patients remaining, 30% of the them were unchanged or improved in the global assessment. Conclusion: Three-year donepezil treatment showed a positive global and cognitive outcome in the routine clinical setting. Copyright © 2007 S. Karger AG.

- OBJECTIVES: To investigate the relationships between episodic memory, APOE genotype, CSF markers (total tau, T-tau; phospho-tau, P-tau; beta-amyloid, Abeta42) and longitudinal cognitive decline. METHODS: 124 memory clinic patients were retrospectively divided into 6 groups based on (i) episodic memory function (Rey Auditory Verbal Learning Test, RAVLT): severe, moderate or no impairment (SIM, MIM or NIM), and (ii) APOE genotype (epsilon4+ or epsilon4-). CSF marker levels and cognitive decline were compared across groups. RESULTS: Episodic memory function, according to RAVLT scores, was significantly correlated with CSF marker levels only among epsilon4+ subjects and not among epsilon4- subjects. When comparing the 6 subgroups, SIM epsilon4+ and MIM epsilon4+ groups showed significantly lower Abeta42 levels than the other groups. T-tau and P-tau levels were significantly increased in SIM epsilon4+ when compared to all the other groups, including the SIM epsilon4- group. However, both SIM epsilon4+ and SIM epsilon4- declined cognitively during the follow-up. CONCLUSION: It remains to be determined whether APOE genotype affects the expression of biomarkers in CSF, or whether the different biomarker patterns reflect different types of disease processes in patients with progressive cognitive dysfunction.

- <i>Background:</i> Individuals with Down syndrome (DS) invariably develop Alzheimer’s disease (AD) during their life span. It is therefore of importance to study young DS patients when trying to elucidate early events in AD pathogenesis. <i>Aim:</i> To investigate how levels of different amyloid-β (Aβ) peptides, as well as tau and phosphorylated tau, in cerebrospinal fluid (CSF) from children with DS change over time. The first CSF sample was taken at 8 months and the following two samples at 20–40 and 54 months of age. <i>Results:</i> Individual levels of the Aβ peptides, as well as total Aβ levels in CSF increased over time when measured with Western blot. Tau in CSF decreased whereas there was no change in levels of phosphorylated tau over time. <i>Conclusion:</i> The increasing levels of Aβ in CSF during early childhood of DS patients observed in this study are probably due to the trisomy of the Aβ precursor APP, which leads to an overproduction of Aβ. Despite the increased CSF concentrations of Aβ, there were no signs of an AD-indicating tau pattern in CSF, since the levels of total tau decreased and phosphorylated tau remained unchanged. This observation further strengthens the theory of Aβ pathology preceding tau pathology in AD.

- BACKGROUND: omega-3 fatty acids (omega-3 FAs) found in dietary fish or fish oils are anti-inflammatory agents that may influence Alzheimer's disease (AD).OBJECTIVE: To study the effects of dietary omega-3 FA supplementation on inflammatory markers in cerebrospinal fluid (CSF) and plasma from patients with mild to moderate AD.METHODS: Thirty-five patients (70.3 +/- 8.2 years) were randomized to a daily intake of 2.3 g omega-3 FAs or placebo for 6 months. The inflammatory markers interleukin (IL)-6, tumour necrosis factor-alpha and soluble interleukin-1 receptor type II (sIL-1RII) were analysed in CSF and plasma at baseline and at 6 months. The AD markers tau-protein, hyperphosphorylated tau-protein and beta-amyloid (Abeta(1-42)) were assessed in CSF. High-sensitivity C-reactive protein was assessed in plasma. A possible relation to the APOE genotype was investigated.RESULTS: There was no significant treatment effect of omega-3 FAs on inflammatory and AD biomarkers in CSF or on inflammatory markers in plasma, nor was there any relation with APOE. A significant correlation was observed at baseline between sIL-1RII and Abeta(1-42) levels in CSF.CONCLUSIONS: Treatment of AD patients with omega-3 FAs for 6 months did not influence inflammatory or biomarkers in CSF or plasma. The correlation between sIL-1RII and Abeta(1-42) may reflect the reciprocal interactions between IL-1 and Abeta peptides.

- PURPOSE: To examine living setting and need for ADL assistance before and one year after a first-ever stroke with special focus on gender differences. METHODS: One-year survivors from a population-based stroke study (n = 377) were studied with regard to place of living, need for ADL assistance and who provided the help. Stroke severity, cognitive impairment, post-stroke depression as well as risk factors were evaluated. RESULTS: Before the stroke 48 patients (13%) lived in special housing (service flats or nursing homes), and one year after the stroke, 50 of the survivors (20%) lived in such accommodations. Before the stroke, 80 (21%) of the patients needed help with their personal ADL, while 90 (36%) needed help after one year. The increased need was fulfilled by relatives. Female spouses more often helped their male counterparts, and they tended to accept a heavier burden. Age, living alone, stroke severity, cognitive impairment, pre-stroke ADL dependency and depression were predictors for special housing. CONCLUSIONS: In a time when more and more stroke survivors are cared for at home, it is important to pay attention to the situation of the caregivers. Female caregivers seem to be in an especially exposed position by accepting a heavier burden.

- BACKGROUND: Little is known about longitudinal changes of cerebrospinal fluid (CSF) biomarkers during cognitive decline in neurodegenerative disease progression. OBJECTIVE: To investigate longitudinal changes in CSF biomarkers--total-tau (T-tau), phospho-tau (P-tau) and beta-amyloid (Abeta42)--during cognitive decline. METHODS: Forty memory clinic patients (47.5% females), aged 61.3+/-7.6 (S.D.) years, non-demented at baseline, underwent lumbar puncture and neuropsychological testing at two occasions. Baseline mean MMSE-score was 28.3+/-1.8. Patients were divided into three groups based on baseline memory functioning; severely impaired (SIM), moderately impaired (MIM) and no impairment (NIM). RESULTS: There was a significant increase in P-tau in the SIM-group during follow-up, while P-tau in MIM and NIM did not change. Eighty-three percent of the SIM-patients converted to dementia (80% AD), while most MIM- and NIM-patients remained non-demented. T-tau- and Abeta42-levels did not change in any of the memory groups during follow-up. CONCLUSION: Increasing P-tau levels during cognitive decline and conversion to dementia suggest that P-tau may be useful as a longitudinal marker of the neurodegenerative process.

- Background: Epidemiological and animal studies have suggested that dietary fish or fish oil rich in omega-3 fatty acids (ω3), docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), may have effects in psychiatric and behavioral symptoms in Alzheimer's disease (AD). An association with APOEω4 carriers and neuropsychiatric symptoms in AD has also been suggested. Objective: To determine effects of dietary ω3 supplementation to AD patients with mild to moderate disease on psychiatric and behavioral symptoms, daily functions and a possible relation to APOEgenotype. Methods: Randomized, double-blind, placebo-controlled clinical trial where 204 AD patients (74 ± 9 years) with acetylcholine esterase inhibitor treatment and a MMSE >15 points were randomized to daily intake of 1.7 g DHA and 0.6 g EPA (ω3 group) or placebo for 6 months. Then, all received the ω3 supplementation for 6 more months. Neuropsychiatric symptoms were measured with Neuropsychiatric Inventory (NPI) and Montgomery Åsberg Depression Scale (MADRS). Caregivers burden and activities of daily living (Disability Assessment for Dementia, DAD) were also assessed. Results: One hundred and seventy-four patients fulfilled the trial. 72% were APOEω4 carriers. No significant overall treatment effects on neuropsychiatric symptoms, on activities of daily living or on caregiver's burden were found. However, significant positive treatment effects on the scores in the NPI agitation domain in APOEω4 carriers (p = 0.006) and in MADRS scores in non-APOEω4 carriers (p = 0.005) were found. Conclusions: Supplementation with ω3 in patients with mild to moderate AD did not result in marked effects on neuropsychiatric symptoms except for possible positive effects on depressive symptoms (assessed by MADRS) in non-APOEω4 carriers and agitation symptoms (assessed by NPI) in APOEω4 carriers.
