    • 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.

  • Omega-3 supplementation in mild to moderate Alzheimer's disease : effects on neuropsychiatric symptoms
  • 2008
  • Ingår i: International Journal of Geriatric Psychiatry. - : Wiley. - 0885-6230 .- 1099-1166. ; 23:2, s. 161-169
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Omega-3 fatty acid supplementation effects on weight and appetite in patients with Alzheimer's disease : the omega-3 Alzheimer's disease study
  • 2009
  • Ingår i: Journal of The American Geriatrics Society. - : Wiley. - 0002-8614 .- 1532-5415. ; 57:1, s. 11-17
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To study the effects of omega (Omega)-3 fatty acid (FA) supplements on weight and appetite in patients with mild to moderate Alzheimer's disease (AD) in relation to inflammatory biomarkers and apolipoprotein E epsilon4 (APOEepsilon4). DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING: Specialist memory clinics in the Stockholm catchment area. PARTICIPANTS: Two hundred four patients (aged 73+/-9, 52% women) with mild to moderate AD. INTERVENTION: Patients with AD received 1.7 g of docosahexaenoic acid (DHA) and 0.6 g of eicosapentaenoic acid (EPA) (Omega-3/Omega-3 group; n=89, aged 73+/-9, 57% women) or placebo 0.6 g of linoleic acid per day (placebo/Omega-3 group; n=85, aged 73+/-9, 46% women) for 6 months. After 6 months, all patients received DHA and EPA for another 6 months. MEASUREMENTS: Anthropometry, biochemical nutritional and inflammatory markers, and appetite assessed by caregiver. RESULTS: Mean weight and body mass index (kg/m(2)) at baseline were 70.0+/-11.8 kg and 24.3+/-3.0 kg/m(2), respectively. At 6- and 12-month follow-up, weight had increased 0.7+/-2.5 kg (P=.02) and 1.4+/-2.9 kg (P<.001) in the Omega-3/Omega-3 group. In the placebo group, weight was unchanged at 6 months but had increased (P=.01) at 12 months follow-up after Omega-3 supplementation was initiated. Appetite improved in the Omega-3/Omega-3 group over the treatment period (P=.01). In logistic regression analyses, not carrying the APOEepsilon4 allele and high plasma DHA concentrations were independently related to weight gain in the combined group of patients at 6 months follow-up. CONCLUSION: A DHA-enriched Omega-3 FA supplement may positively affect weight and appetite in patients with mild to moderate AD. Not carrying the APOEepsilon4 allele and high DHA were independently associated with weight gain.
