PURPOSE: Depression is common in adolescents and long-chain polyunsaturated fatty acids (LCPUFA) are suggested to be associated with depression. However, research in adolescents is limited. Furthermore, self-esteem has never been studied in relation to LCPUFA. The objective here was to determine associations of depression and self-esteem with eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), Omega-3 Index (O3I), n-6 docosapentaenoic acid (n-6 DPA, also called Osbond acid, ObA), n-3 docosapentaenoic acid (DPA), and arachidonic acid (AA) concentrations in blood of adolescents attending lower general secondary education (LGSE)...

One of the typical symptoms of a psychological crisis is depression, an increasing concern in the elderly population. Although omega-3-polyunsaturated fatty acids (PUFAs) are reported to be promising nutrients for treating depression, currently, there are no systematic reviews or meta-analyses of randomized control trials that provide critical evidence regarding the potential benefits of omega-3 fatty acids in elderly patients with depression. This analysis was conducted to provide evidence for the clinical application of omega-3 fatty acids in the treatment of depressive symptoms of elderly subjects older than 65 years...

RATIONALE: Depression is a leading cause of disease burden and disability for older adults; thus, prevention is a priority. Biologic and observational data support potential mental health benefits of vitamin D and omega-3 fatty acids; however, it is unclear whether these supplements can prevent late-life depression. DESIGN: We describe the novel methodology of a large-scale prevention study: VITAL-DEP (VITamin D and OmegA-3 TriaL-Depression Endpoint Prevention), an ancillary to the VITAL trial...

The health benefits of fish oil, and its omega-3 long chain polyunsaturated fatty acid content, have attracted much scientific attention in the last four decades. Fish oils that contain higher amounts of eicosapentaenoic acid (EPA; 20:5n-3) than docosahexaenoic acid (DHA; 22:6n-3), in a distinctive ratio of 18/12, are typically the most abundantly available and are commonly studied. Although the two fatty acids have traditionally been considered together, as though they were one entity, different physiological effects of EPA and DHA have recently been reported...

Omega-3 polyunsaturated fatty acids (n-3 or omega-3 PUFAs) and melatonin receptor agonist ramelteon (RMT) both display antidepressant effects, while their cellular effects on anti-oxidative and neuroprotective mechanisms might be different. In this study, we aimed to decipher the individual and synergistic actions of n-3 PUFAs and RMT, as compared with the conventional antidepressant fluoxetine (FLX), in a cellular model of oxidative stress, which might play an important role in the pathophysiology of depression and associated disorders...

SCOPE: Recent studies have shown that omega-3 polyunsaturated fatty acids enriched phospholipids (n-3 PUFA-PLs) have beneficial effects on memory and cognition. However, most reports only attribute the benefit to DHA and pay little attention to EPA. METHODS AND RESULTS: We investigated the effect of EPA-enriched phospholipids on cognitive deficiency in SAMP8 mouse. Ten-month-old SAMP8 mice were fed with 2% (w/w) EPA-PC/PE (EPA: DHA = 46.8%: 3.01%) or 2% EPA-PS (biosynthesized from EPA-PC/PE) for 8 weeks; we then tested the behavioral performances in the Barnes maze test and Morris maze test; the changes of oxidative stress, apoptosis, neurotrophic factors, tau phosphorylation and Aβ pathology were also measured...

Omega-3 polyunsaturated fatty acids (PUFAs) include α-linolenic acid (ALA; 18:3 ω-3), stearidonic acid (SDA; 18:4 ω-3), eicosapentaenoic acid (EPA; 20:5 ω-3), docosapentaenoic acid (DPA; 22:5 ω-3), and docosahexaenoic acid (DHA; 22:6 ω-3). In the past few decades, many epidemiological studies have been conducted on the myriad health benefits of omega-3 PUFAs. In this review, we summarized the structural features, properties, dietary sources, metabolism, and bioavailability of omega-3 PUFAs and their effects on cardiovascular disease, diabetes, cancer, Alzheimer's disease, dementia, depression, visual, and neurological development, as well as maternal and child health...

Depression is the most common psychiatric disorder in the world population and the most frequent mental disorder in a primary health care. Unrecognized and untreated depression is associated with a poor outcome of treated chronic diseases which co-exist with depression. Depression and cardiovascular diseases are bidirectional related conditions, risks are for each other, and they often co-exist. Depression is a common disorder in cardiovascular patients with a prevalence of 20% to 45%, which is much more frequent than in the general population...

Abdominal pain is one of the key symptoms of irritable bowel syndrome (IBS). Studies have indicated an increase in the incidence of IBS in Asia. However, yet the pathophysiology of this disease remains unknown. Women are more likely to develop the condition than men, especially the constipation-predominant type. Essential fatty acid (EFA) malnutrition is one of several theories discussing the mechanism of IBS.The authors hypothesized that significant EFA deficiency may cause abdominal pain in patients with IBS...

There is increasing evidence about the role of nutrients in mental health. An adequate intake of nutrients contributes to better overall health and mental health in particular. Major depression is a severe mental illness with a high prevalence for which effective treatments exist but not in all cases the patient’s remission is achieved. Therefore, it is increasingly aimed at optimizing the supply of nutrients necessary for adequate brain functioning as adjunctive therapy to antidepressant treatment in depressive disorders...

BACKGROUND: Blood levels of polyunsaturated fatty acids (PUFAs) have been associated to current depression. However, it is unclear whether this association extends to remitted depression and to anxiety disorders. This study examined the relationship of PUFAs with the presence and clinical characteristics of depressive and anxiety disorders. METHODS: Cross-sectional data was used from the Netherlands Study of Depression and Anxiety, including persons with current pure depressive disorder (n=304), current pure anxiety disorder (n=548), current comorbid depressive and anxiety disorder (n=529), remitted depressive/anxiety disorder(s) (n=897), and healthy controls (n=634)...

Context • Psychoneuroimmunology is the interdisciplinary study that links behavioral health with the neuroendocrinal system and investigates that link's bidirectional impact on the human immune system. Mechanistic studies have shown how omega-3 polyunsaturated fatty acids (PUFAs), like those found in fish oil, can modulate key pathways involved in inflammation, sympathetic activity, oxidative stress, transcription factors, and inflammatory cytokine production. Objective • The research team intended to investigate the effects that PUFAs have on the brain and the immune system, including the effects of proinflammatory cytokines and oxidative stress, and their therapeutic benefits in major depressive disorder (MDD) and bipolar disorder, either as an alternative monotherapy or a complementary adjunct treatment...
