- 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. ClinicalTrials.gov identifier: NCT00211159.

- ObjectiveTo determine the prevalence of psychotropic drug use in very old persons with and without dementia in two time periods, and describe the patterns of psychotropic drug use between institutions and non-institutions.MethodsDescriptive analysis on a sample of subjects aged 81+ from a population-based study in Stockholm, Sweden. Psychotropic drug use data were collected from the 1987-1989 and 1994-1996 periods of the study. The diagnosis of dementia was based on the DSM III-R.ResultsAbout 41% of the subjects used at least one psychotropic drug in both periods. Women and subjects in institutions more commonly used psychotropic drugs. The most commonly reported were, in rank order, hypnotics-sedatives, anxiolytics, antipsychotics and antidepressants. Hypnotics-sedatives and anxiolytics were the most commonly used in both institutions and non-institutions. More persons with dementia used psychotropic drugs in both periods. The use of newer drugs, for example, SSRI, was evident. Multivariate analyses showed increased risk for psychotropic drug use among subjects in institutions.ConclusionsThis study confirms the high rate of psychotropic drug use in the very old, particularly in persons with dementia. Psychotropic drug use was high among subjects living in institutions.

- Objectives: To investigate the association between chronic subsyndromal symptoms of depression (SSD), cerebrospinal fluid (CSF) biomarkers, and neuropsychological performance in individuals with mild cognitive impairment (MCI). Methods: Participants included 238 older adults diagnosed with MCI from the Alzheimer's Disease Neuroimaging Initiative repository with cognitive and CSF amyloid beta (Aβ1–42), total tau (t-tau), and phosphorylated tau (p-tau) data. The Neuropsychiatric Inventory identified individuals with chronic endorsement (SSD group N = 80) or no endorsement (non-SSD group N = 158) of depressive symptoms across timepoints. CSF biomarker and cognitive performance were evaluated with linear regression models adjusting for age, education, gender, APOE genotype, global cognitive status, and SSD group. Results: As compared to the non-SSD group, the SSD group displayed lower CSF Aβ1–42 levels (β = −24.293, S.E. = 6.345, P < 0.001). No group differences were observed for CSF t-tau (P = 0.497) or p-tau levels (P = 0.392). Lower CSF Aβ1–42 levels were associated with poorer performance on learning (β = 0.041, S.E. = 0.018, P = 0.021) and memory (β = −0.012, S.E. = 0.005, P = 0.031) measures, whereas higher CSF t-tau levels were associated with poorer performance on measures of global cognition (β = 0.022, S.E = 0.008, P = 0.007) and language (β = −0.010, S.E = 0.004, P = 0.019). SSD was independently associated with diminished global cognition, learning and memory, language, and executive function performance over and above the effects of CSF biomarkers (all P < 0.05). Conclusions: MCI participants with SSD displayed diminished CSF Aβ1–42 levels but did not differ from non-SSD controls in CSF tau levels. Additionally, CSF biomarkers and SSD independently accounted for variance in cognitive performance, suggesting that these factors may uniquely confer cognitive risk in MCI.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In a just society, everyone should have equal access to healthcare in terms of prevention, assessment, diagnosis, treatment and care. Europe is a multicultural society made up of people who identify with a wide range of ethnic groups. Many older people from minority ethnic groups also have a direct migration background. Several studies have shown that there is a lack of equity in relation to dementia diagnoses and care because equal opportunities do not necessarily translate into equal outcomes. An expert ethics working group led by Alzheimer Europe has produced an extensive report on this issue, a policy brief and a guide for health and social care workers. In this brief summary, the authors/members of the expert working group present some of the key challenges and recommendations for healthcare clinicians striving to provide timely diagnosis and good quality care and treatment to people with dementia from all ethnic groups.
