Abstract
Chronic use of cocaine prompts neurodegeneration and neuroinflammation. Lipids play pivotal roles in neuronal function and pathology. Although evidence correlates cocaine use with the alteration of lipid metabolism in blood and brain, the precise mechanism remains to be elucidated. In this study, we explore the effect of cocaine on neuronal fatty acid profiles in vitro. Neuro2a cells following seven days of repeated exposure to cocaine (0, 600, 800, 1000 μM) showed apoptosis-irrelevant cell death, dysregulated autophagy, activation of atypical endoplasmic reticulum stress response, increased saturated and unsaturated fatty acid synthesis, and disrupted lipid metabolism. These preliminary findings indicated the association between lipid metabolism and cocaine-induced neurotoxicity, which should be beneficial for understanding the neurotoxicity of cocaine.

Abstract
The dopamine transporter (DAT) is a key site of action for cocaine and amphetamines. Dysfunctional DAT is associated with aberrant synaptic dopamine transmission and enhanced drug-seeking and taking behavior. Studies in cultured cells and ex vivo suggest that DAT function is sensitive to membrane cholesterol content. Although it is largely unknown whether psychostimulants alter cholesterol metabolism in the brain, emerging evidence indicates that peripheral cholesterol metabolism is altered in patients with psychostimulant use disorder and circulating cholesterol levels are associated with vulnerability to relapse. Cholesterol interacts with sphingolipids forming lipid raft microdomains on the membrane. These cholesterol-rich lipid raft microdomains serve to recruit and assemble other lipids and proteins to initiate signal transduction. There are two spatially and functionally distinct populations of the DAT segregated by cholesterol-rich lipid raft microdomains and cholesterol-scarce non-raft microdomains on the plasma membrane. These two DAT populations are differentially regulated by DAT blockers (e.g. cocaine), substrates (e.g. amphetamine), and protein kinase C providing distinct cholesterol-dependent modulation of dopamine uptake and efflux. In this chapter, we summarize the impact of depletion and addition of membrane cholesterol on DAT conformational changes between the outward-facing and the inward-facing states, lipid raft-associated DAT localization, basal and induced DAT internalization, and DAT function. In particular, we focus on how the interactions of the DAT with cocaine and amphetamine are influenced by membrane cholesterol. Lastly, we discuss the therapeutic potential of cholesterol-modifying drugs as a new avenue to normalize DAT function and dopamine transmission in patients with psychostimulant use disorder.

Abstract
We have recently reported alterations in the plasma concentrations of lysophosphatidic acid (LPA) in patients with substance use disorders. In order to further explore the potential role of the LPA signaling system as biomarker in cocaine use disorders (CUD) we conducted a cross-sectional study with 105 patients diagnosed with CUD and 92 healthy controls. Participants were clinically evaluated and blood samples were collected to determine plasma concentrations of total LPA and LPA species (16:0-, 18:0-, 18:1-, 18:2-, and 20:4-LPA), and the gene expression of LPA1 and LPA2 receptors in peripheral blood mononuclear cells. We found that patients with CUD had significantly lower plasma concentration of the majority of LPA species, while the mRNA expression of LPA1 receptor was found to be higher than controls. Moreover, we found a positive association between plasma concentration of 20:4-LPA and relevant CUD-related variables: age of onset cocaine use and length of cocaine abstinence. The statistical analysis revealed sex differences in concentrations of total LPA and LPA species, and women showed higher LPA concentrations than men. Furthermore, studies in rats of both sexes showed that plasma concentrations of total LPA were also altered after acute and chronic cocaine administration, revealing a sexual dimorphism in these effects. This study found alterations on the LPA signaling system in both, patients with CUD and rats treated with cocaine. Our results demonstrate that LPA signaling is impacted by CUD and sex, which must be taken into consideration in future studies evaluating LPA as a reliable biomarker for CUD.

Abstract
Disturbances in lipid metabolism in the CNS contribute to neurodegeneration and cognitive impairments. Through tight metabolic coupling, astrocytes provide energy to neurons by delivering lactate and cholesterol and by taking up and processing neuron-derived peroxidated fatty acids (pFA). Disruption of CNS lipid homeostasis is observed in people who use cocaine and in several neurodegenerative disorders, including HIV. The brain's main source of energy is aerobic glycolysis, but numerous studies report a switch to β-oxidation of FAs in response to cocaine. Unlike astrocytes, in response to cocaine, neurons cannot efficiently consume excess pFAs for energy. Accumulation of pFA in neurons induces autophagy and release of pFA. Astrocytes endocytose the pFA for oxidation as an energy source. Our data show that blocking mitochondrial/cytosolic citrate transport reduces the neurotrophic capacity of astrocytes, leading to decreased neuronal fitness.

Abstract
Substance abuse is a chronic relapsing disorder that results in serious health and socioeconomic issues worldwide. Addictive drugs induce long-lasting morphologic and functional changes in brain circuits and account for the formation of compulsive drug-seeking and drug-taking behaviors. Yet, there remains a lack of reliable therapy. In recent years, accumulating evidence indicated that neuroinflammation was implicated in the development of drug addiction. Findings from both our and other laboratories suggest that ω-3 polyunsaturated fatty acids (PUFAs) are effective in treating neuroinflammation-related mental diseases, and indicate that they could exert positive effects in treating drug addiction. Thus, in the present review, we summarized and evaluated recently published articles reporting the neuroinflammation mechanism in drug addiction and the immune regulatory ability of ω-3 PUFAs. We also sought to identify some of the challenges ahead in the translation of ω-3 PUFAs into addiction treatment.

Abstract
The usefulness of polyunsaturated fatty acids on inflammatory, cardiovascular, and the nervous system was studied in the last decades, but the mechanisms underlying their benefic properties are still partially unknown. These agents seem to express their action on the membrane phospholipid composition and permeability and modulation of second messenger cascades. In psychiatry, the efficacy and tolerability of omega-3 fatty acids were investigated in several psychiatric disorders, including major depression, bipolar disorder, personality disorders, high-risk conditions to develop psychosis, attention-deficit hyperactivity disorder, and autism spectrum disorders. Initial findings in this field are promising, and some relevant questions need to be addressed. In particular, the effects of these agents on the main symptom dimensions have to be investigated in a trans-diagnostic perspective. The present systematic review is aimed to examine the available data on the efficacy of omega-3 fatty acids on domains of psychotic symptoms, affective symptoms, impulsivity, and aggressiveness, and harmful behaviors, and suicide risk.

Abstract
Omega-3 (N3) fatty acids are dietary nutrients that are essential for human health. Arguably, one of their most critical contributions to health is their involvement in the structure and function of the nervous system. N3 fatty acids accumulate in neuronal membranes through young adulthood, becoming particularly enriched in a brain region known to be the locus of cognitive control of behavior-the prefrontal cortex (PFC). The PFC undergoes a surge in development during adolescence, coinciding with a life stage when dietary quality and intake of N3 fatty acids tend to be suboptimal. Such low intake may impact neurodevelopment and normative development of cognitive functions suggested to be protective for the risk of subsequent substance and alcohol use disorders (UD). While multiple genetic and environmental factors contribute to risk for and resilience to substance and alcohol use disorders, mounting evidence suggests that dietary patterns early in life may also modulate cognitive and behavioral factors thought to elevate UD risk (e.g., impulsivity and reward sensitivity). This review aims to summarize the literature on dietary N3 fatty acids during childhood and adolescence and risk of executive/ cognitive or behavioral dysfunction, which may contribute to the risk of subsequent UD. We begin with a review of the effects of N3 fatty acids in the brain at the molecular to cellular levels–providing the biochemical mechanisms ostensibly supporting observed beneficial effects. We continue with a review of cognitive, behavioral and neurodevelopmental features thought to predict early substance and alcohol use in humans. This is followed by a review of the preclinical literature, largely demonstrating that dietary manipulation of N3 fatty acids contributes to behavioral changes that impact drug sensitivity. Finally, a review of the available evidence in human literature, suggesting an association between dietary N3 fatty and neurodevelopmental profiles associated with risk of adverse outcomes including UD. We conclude with a brief summary and call to action for additional research to extend the current understanding of the impact of dietary N3 fatty acids and the risk of drug and alcohol UD.

Abstract
BACKGROUND Polyunsaturated fatty acids (PUFA) have been long implicated in the etiopathogenesis of mental illnesses, including disorders characterized by high impulsivity. The objective of most of the studies in this field is to determine the effect of omega-3 supplementation on the impulsive symptoms. In contrast, studies analyzing basal PUFA composition in patients with impulsive behaviors are very scarce, results are not yet conclusive, and to date, no publication has specifically evaluated this in gambling disorder. Therefore, the main purpose of this research is to examine the relationship between basal PUFA composition of plasma and erythrocyte membrane and impulsivity in subjects with gambling disorder. METHODS It is an observational and cross-sectional study. The sample consisted of fifty-five men with gambling disorder, who voluntarily accepted to participate. Basal composition of PUFA in plasma and erythrocyte membrane was assessed by gas chromatography and mass spectrometry. Trait impulsivity was measured by the Barratt Impulsiveness Scale version 11 (BIS-11). RESULTS Arachidonic acid (AA)/eicosapentaenoic acid (EPA) ratio in the erythrocyte membrane was negatively correlated with total scores in BIS-11. It was also observed that impulsive gamblers had a higher proportion of EPA and a lower value of AA/EPA and AA/docosahexaenoic acid (DHA) ratio in erythrocyte membrane than non-impulsive gamblers. CONCLUSIONS These results support the hypothesis that alteration of basal PUFA composition exists in disorders characterized by high impulsivity, although the direction of this is still unknown. Unfortunately, the empirical literature on this field is non-existent at the time and we have no direct means to support or refute these outcomes. Further research is needed to determine the relationship between essential fatty acids and disorders characterized by high impulsivity.

Abstract
BACKGROUND Pharmacological treatment for alcohol dependence has only three approved drugs: disulfiram, naltrexone and acamprosate. The effects of these drugs are, however, limited, presenting several side effects and a modestly higher efficacy compared to placebo. The administration of omega-3 might bring new perspectives to relapse prevention. METHODS This systematic review aimed to analyze the available literature, compiling the studies that used omega-3 to prevent relapse in alcohol dependents. RESULTS The databases used were PubMed and Web of Science. We identified 2,231 studies and only five articles addressed the administration of omega-3 and alcoholism. Preclinical studies evaluating the effects of PUFAs related to chronic alcohol administration showed improvements in behavioral, cellular and molecular levels. The clinical trial yielded inconclusive results. CONCLUSION Despite the reduced number of studies, omega-3 interventions seem to be promising for controlling issues related to alcohol dependence.

Abstract
INTRODUCTION Cocaine dependence affects millions of individuals worldwide; however, there are no pharmacotherapeutic and/or diagnostic solutions. Recent evidence suggests a role for lipid signaling in the development and maintenance of addiction, highlighting the need to understand how lipid remodeling mediates neuroadaptation after cocaine exposure. METHODS This study utilized shotgun lipidomics to assess cocaine-induced lipid remodeling in rats using a novel behavioral regimen that incorporated multiple sessions of extinction training and reinstatement testing. RESULTS Mass spectrometric imaging demonstrated widespread decreases in phospholipid (PL) abundance throughout the brain, and high-spatial resolution matrix-assisted laser desorption/ionization Fourier-transform ion cyclotron resonance mass spectrometry indicated hippocampus-specific PL alterations following cocaine exposure. We analyzed the expression of genes involved in hippocampal lipid metabolism and observed region-specific regulation. In addition, we found that cocaine exposure differentially regulates mitochondrial biogenesis in the brain. CONCLUSIONS This work presents a comprehensive lipidomic assessment of cocaine-induced lipid remodeling in the rat brain. Further, these findings indicate a potential interplay between CNS energetics and differential lipid regulation and suggest a role for cocaine in the maintenance of energy homeostasis.

Omega-3 decreases D1 and D2 receptors expression in the prefrontal cortex and prevents amphetamine-induced conditioned place preference in rats. J Nutr Biochem 2019; 67:182-189. [PMID: 30951972 DOI: 10.1016/j.jnutbio.2019.02.007] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2018] [Revised: 02/13/2019] [Accepted: 02/28/2019] [Indexed: 01/09/2023]
Abstract
Amphetamine (AMPH) abuse is a serious public health problem due to the high addictive potential of this drug, whose use is related to severe brain neurotoxicity and memory impairments. So far, therapies for psychostimulant addiction have had limited efficacy. Omega-3 polyunsaturated fatty acids (n-3 PUFA) have shown beneficial influences on the prevention and treatment of several diseases that affect the central nervous system. Here, we assessed the influence of fish oil (FO), which is rich in n-3 PUFA, on withdrawal and relapse symptoms following re-exposure to AMPH. Male Wistar rats received d,l-AMPH or vehicle in the conditioned place preference (CPP) paradigm for 14 days. Then, half of each experimental group was treated with FO (3 g/kg, p.o.) for 14 days. Subsequently, animals were re-exposed to AMPH-CPP for three additional days, in order to assess relapse behavior. Our findings have evidenced that FO prevented relapse induced by AMPH reconditioning. While FO prevented AMPH-induced oxidative damages in the prefrontal cortex, molecular assays allowed us to observe that it was also able to modulate dopaminergic cascade markers (DAT, TH, VMAT-2, D1R and D2R) in the same brain area, thus preventing AMPH-induced molecular changes. To the most of our knowledge, this is the first study to show a natural alternative tool which is able to prevent psychostimulant relapse following drug withdrawal. This non-invasive and healthy nutraceutical may be considered as an adjuvant treatment in detoxification clinics.

BMC Neurosci 2018; 19:4.

Abstract
Background Understanding the process of relapse to abused drugs and ultimately developing treatments that can reduce the incidence of relapse remains the primary goal for the study of substance dependence. Therefore, exploring the metabolite characteristics during the relapse stage is valuable. Methods A heroin self-administered rat model was employed, and analysis of the 1H-nuclear magnetic resonance-based metabolomics was performed to investigate the characteristic metabolite profile upon reintroduction to the drug after abstinence. Results Sixteen metabolites in the serum of rats, including phospholipids, intermediates in TCA (Tricarboxylic Acid Cycle) cycle, keto bodies, and precursors for neurotransmitters, underwent a significant change in the reinstatement stage compared with those in the control group. In particular, energy production was greatly disturbed as evidenced by different aspects such as an increase in glucose and decrease in intermediates of glycolysis and the TCA cycle. The finding that the level of 3-hydroxybutyrate and acetoacetate increased significantly suggested that energy production was activated from fatty acids. The concentration of phenylalanine, glutamine, and choline, the precursors of major neurotransmitters, increased during the reinstatement stage which indicated that an alteration in neurotransmitters in the brain might occur along with the disturbance in substrate supply in the circulatory system. Conclusions Heroin reinforcement resulted in impaired energy production via different pathways, including glycolysis, the TCA cycle, keto body metabolism, etc. A disturbance in the substrate supply in the circulatory system may partly explain heroin toxicity in the central nervous system. These findings provide new insight into the mechanism underlying the relapse to heroin use.

Abstract
Previous studies have demonstrated a link between protease inhibitor (PI)-based therapy and lipid dysregulation. The main objective of this study was to examine whether cocaine use may modify PI-associated dyslipidemia in adults. Between June 2003 and June 2014, 957 human immunodeficiency virus (HIV)-infected participants in Baltimore, Maryland were enrolled in a study that investigated HIV/antiretroviral therapy-associated comorbidities. Multiple linear and logistic regression models were fitted to examine the associations between PI therapy and lipid profiles for the pooled sample and cocaine use subgroups, respectively. Total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), TC/high-density lipoprotein cholesterol (HDL-C) ratio, and atherogenic index of plasma (AIP) levels were positively associated with duration of PI-based therapy in long-term cocaine users (all p < 0.05). However, longer-term PI therapy was significantly associated with increased HDL-C in non-chronic cocaine users (β = 0.109, SE = 0.042, p < 0.05). The participants who received PI therapy ≥12 months and used cocaine ≥15 years were more likely to have hypertriglyceridemia (OR = 2.82, 95% CI = 1.63, 4.88) and abnormal AIP (OR = 1.73, 95% CI = 1.08, 2.79) as compared to their counterparts. Our findings showed that long-term cocaine use may exacerbate adverse effects of PI therapy on lipid metabolism, suggesting that reduced cocaine use may be considered an alternative approach to managing PI-associated dyslipidemia in chronic cocaine users with HIV infection.

Abstract
Lipids are predominant components of the brain and key regulators for neural structure and function. The neuropsychopharmacological effect of cocaine has been intensively investigated; however, the impact of cocaine on brain lipid profiles is largely unknown. In this study, we used a LC-MS-based lipidomic approach to investigate the impact of cocaine on brain lipidome in two mouse models, cocaine-conditioned place preference (CPP) and hyperlocomotor models and the lipidome was profoundly modified in the nucleus accumbens (NAc) and striatum respectively. We comprehensively analyzed the lipids among 21 subclasses across 7 lipid classes and found that cocaine profoundly modified brain lipidome. Notably, the lipid metabolites significantly modified were sphingolipids and glycerophospholipids in the NAc, showing a decrease in ceramide and an increase in its up/downstream metabolites levels, and decrease lysophosphatidylcholine (LPC) and lysophosphoethanolamine (LPE) and increase phosphatidylcholine (PC) and phosphatidylethanolamines (PE) levels, respectively. Moreover, long and polyunsaturated fatty acid phospholipids were also markedly increased in the NAc. Our results show that cocaine can markedly modify brain lipidomic profiling. These findings reveal a link between the modified lipidome and psychopharmacological effect of cocaine, providing a new insight into the mechanism of cocaine addiction.

Abstract
BACKGROUND Lipid profiles in the blood are altered in human cocaine users, suggesting that cocaine exposure can induce lipid remodeling. METHODS Lipid changes in the brain tissues of rats sensitized to cocaine were determined through shotgun lipidomics using electrospray ionization-mass spectrometry (ESI-MS). We also performed pairwise principal component analysis (PCA) to assess cocaine-induced changes in blood lipid profiles. Alterations in the abundance of phospholipid species were correlated with behavioral changes in the magnitude of either the initial response to the drug or locomotor sensitization. RESULTS Behavioral sensitization altered the relative abundance of several phospholipid species in the hippocampus and cerebellum, measured one week following the final exposure to cocaine. In contrast, relatively few effects on phospholipids in either the dorsal or the ventral striatum were observed. PCA analysis demonstrated that cocaine altered the relative abundance of several glycerophospholipid species as compared to saline-injected controls in blood. Subsequent MS/MS analysis identified some of these lipids as phosphatidylethanolamines, phosphatidylserines and phosphatidylcholines. The relative abundance of some of these phospholipid species were well-correlated (R(2) of 0.7 or higher) with either the initial response to cocaine or locomotor sensitization. CONCLUSION Taken together, these data demonstrate that a cocaine-induced sensitization assay results in the remodeling of specific phospholipids in rat brain tissue in a region-specific manner and also alters the intensities of certain types of phospholipid species in rat blood. These results further suggest that such changes may serve as biomarkers to assess the neuroadaptations occurring following repeated exposure to cocaine.

Abstract
Chronic consumption of processed food causes structural changes in membrane phospholipids, affecting brain neurotransmission. Here we evaluated noxious influences of dietary fats over two generations of rats on amphetamine (AMPH)-conditioned place preference (CPP). Female rats received soybean oil (SO, rich in n-6 fatty acids (FA)), fish oil (FO, rich in n-3 FA) and hydrogenated vegetable fat (HVF, rich in trans fatty acids (TFA)) for two successive generations. Male pups from the 2nd generation were maintained on the same supplementation until 41 days of age, when they were conditioned with AMPH in CPP. While the FO group showed higher incorporation of n-3 polyunsaturated-FA (PUFA) in cortex/hippocampus, the HVF group showed TFA incorporation in these same brain areas. The SO and HVF groups showed AMPH-preference and anxiety-like symptoms during abstinence. Higher levels of protein carbonyl (PC) and lower levels of non-protein thiols (NPSH) were observed in cortex/hippocampus of the HVF group, indicating antioxidant defense system impairment. In contrast, the FO group showed no drug-preference and lower PC levels in cortex. Cortical PC was positively correlated with n-6/n-3 PUFA ratio, locomotion and anxiety-like behavior, and hippocampal PC was positively correlated with AMPH-preference, reinforcing connections between oxidative damage and AMPH-induced preference/abstinence behaviors. As brain incorporation of trans and n-6 PUFA modifies its physiological functions, it may facilitate drug addiction.

Abstract
Omega-3 fatty acids have received increasing interest due to their effects in stabilizing plasmatic membranes and regulating cell signaling. The efficacy of omega-3 fatty acids in psychiatric disorders, in particular mood disorders, has been studied. There have been two trials on eicosapentanoic acid (EPA) and docosahexanoic acid (DHA) in the treatment of borderline personality disorder (BPD). The present 12-week controlled trial aimed to assess the efficacy of the association of EPA and DHA with valproic acid, compared to single valproic acid, in 43 consecutive BPD outpatients. Participants were evaluated at baseline and after 12 weeks with: Clinical Global Impression - Severity (CGI-S), Hamilton Scales for depression and anxiety (HAM-D, HAM-A), Social and Occupational Functioning Assessment Scale (SOFAS), borderline personality disorder severity index (BPDSI), Barratt Impulsiveness Scale - version 11 (BIS-11), Modified Overt Aggression Scale (MOAS), Self-Harm Inventory (SHI) and Dosage Record Treatment Emergent Symptom Scale (DOTES).

Abstract
Background The lipid fraction of cell membranes consists of polyunsaturated fatty acids (PUFAS), and chronic alcohol use alters it, modifying its permeability, what might contribute for the dysfunctional metabolism observed in the central nervous system of alcohol dependent patients. Therefore, the supplementation of PUFAS can be an important adjuvant in alcoholism treatment. Methods This was a placebo controlled, double blind, randomized study where, 80 alcohol dependent patients, according to DSM-IV, were allocated in four groups with 20 patient each: 'PUFAS', 'Naltrexone', 'Naltrexone + PUFAS' and 'Placebo'. Those substances were administered for 90 days and scales were applied to assess patients craving (OCDS) and alcohol dependence severity (SADD) at baseline and after 90 days. PUFAS serum levels were assessed before and after treatment by high performance liquid chromatography assay. Results Forty-three patients completed the trial. There was a significant improvement over time on drinking days, SADD and OCDS scores in all groups (p < 0.001). The drinking days comparison between groups did not show statistical significant difference. The same effect was observed for compulsion (OCDS) and severity of dependence scale (SADD). The serum levels of PUFAS increased in all the supplemented groups after treatment, although not significantly. Conclusions The oral supplementation of 2 g PUFAS for 3 months did not significantly differ from placebo in reducing the amount of alcohol ingestion, or OCDS and SADD scores in a group of alcohol dependent patient.

Abstract
In the United States the rates for some mental, emotional, and behavioral problems (MEBs) have objectively increased over the past 20 to 50 years. The attributes of a public health approach to the treatment of MEBs are defined in this article. Multiple examples of how public health approaches might reduce or prevent MEBs using low-cost evidence-based kernels, which are fundamental units of behavior, are discussed. Such kernels can be used repeatedly, which then act as "behavioral vaccines" to reduce morbidity or mortality and/or improve human wellbeing. The author calls for 6 key policy actions to improve MEBs in young people.

Abstract
The polyunsaturated fatty acids (PUFAs), especially omega-3 and -6, play an important role in the functioning of membranes. Therefore, changes in their physical properties might entail impairment of the neurotransmission between cells. Studies emphasize the importance of omega-3 intakes, but they also highlight the need of a balance between omega-6 and -3, whose ideal ratio should be 4:1. The Western diet has very high amounts of saturated fat and omega-6, which might contribute, at least partially, to physiopathologies and high incidence as well as prevalence of psychiatric and neurodegenerative diseases. This narrow review aimed at systematizing the studies on the importance of PUFAs in some particular cases, that is, the extremes of life: pre- and post-natal development, and cognitive aging. Additionally, it aimed at studying the association between PUFAs and substance abuse disorders. We used the databases LILACs, MEDLINE and PUBMED.

Serum omega-3 fatty acids are associated with variation in mood, personality and behavior in hypercholesterolemic community volunteers. Psychiatry Res 2007; 152:1-10. [PMID: 17383013 DOI: 10.1016/j.psychres.2006.10.006] [Citation(s) in RCA: 59] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2006] [Revised: 09/12/2006] [Accepted: 10/01/2006] [Indexed: 10/23/2022]
Abstract
Low dietary intake of omega-3 polyunsaturated fatty acids has been linked to several features of psychiatric symptomatology, including depression, disorders of impulse control, and hostility. Preliminary intervention trials of omega-3 fatty acid supplementation for clinical depression and other disorders have reported benefit. However, few studies have investigated the relationships between these fatty acids and normative variability in mood, behavior and personality. Participants were 105 hypercholesterolemic, but otherwise healthy, non-smoking adults. Fasting serum alpha-linolenic (alpha-LNA), eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) were assayed with gas chromatography. Participants completed the Beck Depression Inventory (BDI), the NEO Five Factor Personality Inventory (NEO-FFI) and the Barratt Impulsiveness Scale (BIS). In multivariate analyses, higher levels of the long chain omega-3 PUFAs, EPA and DHA, were associated with significantly reduced odds of scoring >or=10 on the BDI. Similarly, DHA and EPA covaried inversely with NEO-Neuroticism scores, whereas DHA was positively associated with NEO-Agreeableness. On the BIS, DHA was inversely related to cognitive impulsivity and alpha-LNA was inversely related to motor and total impulsivity. These findings suggest that omega-3 fatty acid status is associated with variability in affect regulation, personality and impulse control.

Abstract
There is mounting evidence that low levels of n-3 polyunsaturated fatty acids (PUFAs) play a role in the pathophysiology of a number of psychiatric disorders. Preclinical studies have shown that n-3 PUFAs decrease anxietylike behaviors, but there is a paucity of information about their effects on anxiety in humans. In light of our observation that substance abusers have poor dietary habits and the strong association between anxiety disorders and substance use disorders, the possibility that the administration of supplements of n-3 PUFAs would decrease the anxiety level of a group of substance abusers was explored. Thirteen patients were given on a daily basis capsules containing 3 g of n-3 PUFAS (eicosapentaenoic acid + docosahexaenoic acid). Eleven patients received similarly looking placebo capsules containing vegetable oil. The trial was double-blind, randomized, and lasted 3 months. A scale assessing anxiety feelings was administered at baseline and on a monthly basis thereafter. Six PUFA group patients and 8 placebo group patients were followed for an additional 3 months after treatment discontinuation and administered the same questionnaire monthly. Patients who received n-3 PUFAs for 3 months showed a progressive decline in anxiety scores. This was not the case for patients who received placebos. A comparison of the 2 groups was significant (P = 0.010). Anxiety scores remained significantly decreased in the PUFA group for 3 months after treatment discontinuation. A comparison of the 2 groups followed for 6 months was also significant (P = 0.042). In conclusion, these preliminary data indicate that n-3 PUFA supplementation could be beneficial in the treatment of some patients with anxiety disorders.

Abstract
The brain is one of the organs with the highest level of lipids (fats). Brain lipids, formed of fatty acids, participate in the structure of membranes, for instance 50 % fatty acids are polyunsaturated in the gray matter, 1/3 are of the omega-3 family, and are thus of dietary origin. The omega-3 fatty acids (mainly alpha-linolenic acid, ALA) participated in one of the first experimental demonstration of the effect of dietary substances (nutrients) on the structure and function of the brain. Experiments were first of all carried out on ex vivo cultured brain cells, then on in vivo brain cells (neurons, astrocytes and oligodendrocytes) from animals fed ALA deficient diet, finally on physicochemical (membrane fluidity), biochemical, physiological, neurosensory (vision an auditory responses), and behavioural or learning parameters. These findings indicated that the nature of polyunsaturated fatty acids (in particular omega-3) present in formula milks for human infants determines to a certain extend the visual, neurological, and intellectual abilities. Thus, in view of these results and of the high polyunsaturated fatty acid content of the brain, it is normal to consider that they could be involved in psychiatric diseases and in the cognitive decline of ageing. Omega-3 fatty acids appear effective in the prevention of stress, however their role as regulator of mood is a matter for discussion. Indeed, they play a role in the prevention of some disorders including depression (especially post partum), as well as in dementia, particularly Alzheimer's disease. Their role in major depression and bipolar disorder (manic-depressive disease), only poorly documented, is not clearly demonstrated. The intervention of omega-3 in dyslexia, autism, and schizophrenia has been suggested, but it does not necessarily infer a nutritional problems. The respective importance of the vascular system (where the omega-3 are actually active) and the cerebral parenchyma itself, remain to be resolved. However, the insufficient supply of omega-3 fatty acids in today diet in occidental (less than 50 % of the recommended dietary intakes values for ALA) raises the problem of how to correct inadequate dietary habits, by prescribing mainly rapeseed (canola) and walnut oils on the one hand, fatty fish (wild, or farmed, but the nature of fatty acids present in fish flesh is the direct consequence of the nature of fats with which they have been fed), and eggs from laying hens fed omega-3 fatty acids.
