Depression and low mood الاكتئاب

وَتَوَلَّىٰ عَنۡهُمۡ وَقَالَ يَٰٓأَسَفَىٰ عَلَىٰ يُوسُفَ وَٱبۡيَضَّتۡ عَيۡنَاهُ مِنَ ٱلۡحُزۡنِ فَهُوَ كَظِيمࣱ‏

and he turned away from them, saying, ‘Alas for Joseph!’ His eyes went white with grief and he was filled with sorrow

وَقَالُواْ ٱلۡحَمۡدُ لِلَّهِ ٱلَّذِيٓ أَذۡهَبَ عَنَّا ٱلۡحَزَنَۖ إِنَّ رَبَّنَا لَغَفُورࣱ شَكُورٌ

They will say, ‘Praise be to God, who has separated us from all sorrow! Our Lord is truly most forgiving, most appreciative

إِذۡ تَمۡشِيٓ أُخۡتُكَ فَتَقُولُ هَلۡ أَدُلُّكُمۡ عَلَىٰ مَن يَكۡفُلُهُۥۖ فَرَجَعۡنَٰكَ إِلَىٰٓ أُمِّكَ كَيۡ تَقَرَّ عَيۡنُهَا وَلَا تَحۡزَنَۚ وَقَتَلۡتَ نَفۡسࣰ ا فَنَجَّيۡنَٰكَ مِنَ ٱلۡغَمِّ وَفَتَنَّٰكَ فُتُونࣰ اۚ فَلَبِثۡتَ سِنِينَ فِيٓ أَهۡلِ مَدۡيَنَ ثُمَّ جِئۡتَ عَلَىٰ قَدَرࣲ يَٰمُوسَىٰ

Your sister went out, saying, “I will tell you someone who will nurse him,” then We returned you to your mother so that she could rejoice and not grieve. Later you killed a man, but We saved you from distress and tried you with other tests. You stayed among the people of Midian for years, then you came here as I ordained

أَهَٰٓؤُلَآءِ ٱلَّذِينَ أَقۡسَمۡتُمۡ لَا يَنَالُهُمُ ٱللَّهُ بِرَحۡمَةٍۚ ٱدۡخُلُواْ ٱلۡجَنَّةَ لَا خَوۡفٌ عَلَيۡكُمۡ وَلَآ أَنتُمۡ تَحۡزَنُونَ

And are these the people you swore God would never bless? [Now these people are being told], “Enter the Garden! No fear for you, nor shall you grieve.”’

۞إِذۡ تُصۡعِدُونَ وَلَا تَلۡوُۥنَ عَلَىٰٓ أَحَدࣲ وَٱلرَّسُولُ يَدۡعُوكُمۡ فِيٓ أُخۡرَىٰكُمۡ فَأَثَٰبَكُمۡ غَمَّۢا بِغَمࣲّ لِّكَيۡلَا تَحۡزَنُواْ عَلَىٰ مَا فَاتَكُمۡ وَلَا مَآ أَصَٰبَكُمۡۗ وَٱللَّهُ خَبِيرُۢ بِمَا تَعۡمَلُونَ

You fled without looking back while the Messenger was calling out to you from behind, and God rewarded you with sorrow for sorrow. [He has now forgiven you] so that you may not grieve for what you missed or for what happened to you. God is well aware of everything you do

ثُمَّ أَنزَلَ عَلَيۡكُم مِّنۢ بَعۡدِ ٱلۡغَمِّ أَمَنَةࣰ نُّعَاسࣰ ا يَغۡشَىٰ طَآئِفَةࣰ مِّنكُمۡۖ وَطَآئِفَةࣱ قَدۡ أَهَمَّتۡهُمۡ أَنفُسُهُمۡ يَظُنُّونَ بِٱللَّهِ غَيۡرَ ٱلۡحَقِّ ظَنَّ ٱلۡجَٰهِلِيَّةِۖ يَقُولُونَ هَل لَّنَا مِنَ ٱلۡأَمۡرِ مِن شَيۡءࣲۗ قُلۡ إِنَّ ٱلۡأَمۡرَ كُلَّهُۥ لِلَّهِۗ يُخۡفُونَ فِيٓ أَنفُسِهِم مَّا لَا يُبۡدُونَ لَكَۖ يَقُولُونَ لَوۡ كَانَ لَنَا مِنَ ٱلۡأَمۡرِ شَيۡءࣱ مَّا قُتِلۡنَا هَٰهُنَاۗ قُل لَّوۡ كُنتُمۡ فِي بُيُوتِكُمۡ لَبَرَزَ ٱلَّذِينَ كُتِبَ عَلَيۡهِمُ ٱلۡقَتۡلُ إِلَىٰ مَضَاجِعِهِمۡۖ وَلِيَبۡتَلِيَ ٱللَّهُ مَا فِي صُدُورِكُمۡ وَلِيُمَحِّصَ مَا فِي قُلُوبِكُمۡۚ وَٱللَّهُ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ

After sorrow, He caused calm to descend upon you, a sleep that overtook some of you. Another group, caring only for themselves, entertained false thoughts about God, thoughts more appropriate to pagan ignorance, and said, ‘Do we get a say in any of this?’ [Prophet], tell them, ‘Everything to do with this affair is in God’s hands.’ They conceal in their hearts things they will not reveal to you. They say, ‘If we had had our say in this, none of us would have been killed here.’ Tell them, ‘Even if you had resolved to stay at home, those who were destined to be killed would still have gone out to meet their deaths.’ God did this in order to test everything within you and in order to prove what is in your hearts. God knows your innermost thoughts very well

" Oh, my grief for Joseph! " And his eyes turned white because of the sorrow that he was suppressing. Revelation came from the Compeller of all engendered beings: " O Jacob! You grieve so much for him, but you do not grieve for what you are missing of Me by being busy with grief for him! " O Jacob, how long this sorrow and regret at separation from Joseph? How long will you suffer grief and coldly sigh? Do you not suffer grief that you are held back from Me while busy with him? " With two kiblahs you can't walk straight on the road of tawḤīd- either the Friend's approval, or your own caprice. [DS 488] " O Jacob! Be careful not to pass Joseph's name over your tongue any more, or I will remove your name from the register of the prophets. " The Pir of the Tariqah said, " Jacob's remembrance of Joseph was the seed of heartache, and Joseph's remembrance of Jacob was the seed of ease. Since Ja

And they shall say, “Praise belongs to God, who has put away sorrow from us.” O chevalier! The worth of the antidote is known by the snake-bitten, the worth of burning fire is known by the moth, the worth of Joseph's shirt is known by grieving Jacob. When someone is de- luded by his own safety and is given the antidote, how will he know its worth? If you want some- one to know the worth and gravity of the antidote, you need him whose spirit has reached his lips. A poor man is needed, broken-hearted, suffering pain, and burdened with grief to know the worth of this caress and the exaltedness of this address: “Praise belongs to God, who has put away sorrow from us.” Wait until tomorrow when that wounded-hearted poor man is placed on the throne of joy in the palisade of holiness while the serving boys and servants act like his slaves to spread the carpet before the seat of his good fortune.

And We tried thee with trials. In other words, “We cooked you well with trial until you became limpid and immaculate, then We took you totally to Ourselves, so that you would not belong to any other.” “O Moses, We took you to the oven of trial and put you into self-purification so that nothing would remain in your heart but My love and nothing on your tongue but My remembrance.” What were those trials and troubles that sat on his head? When he was first born he was born in secrecy, in a house without lamp, poor, without pleasures. His mother could not have a son be- cause of fear of Pharaoh, who was killing sons. She put him into the casket and threw it in the river. His first home was the river. His second home was the sword, the execution ground, and seeing the enemy. His third home was fear of the Egyptians, because he had killed one of them. Then he fled looking back at them, his hea

And he turned away from them no longer addressing them and said ‘Alas my grief for Joseph!’ yā asafā the final alif of asafā has taken the place of the possessive yā’ of genitive annexation sc. yā asafī in other words it means yā huznī ‘O my sorrow’. And his eyes turned white their dark colour was effaced and became white on account of his tears with grief for him such that he was filled with suppressed agony anguished and grief-stricken but not manifesting his grief.

And they will say ‘Praise be to God Who has removed all grief from us. Truly our Lord is Forgiving of sins Appreciative of obedience

Are these the ones of whom you swore that God would never grant them mercy?’ it has already been said to them ‘Enter Paradise; no fear shall come upon you nor shall you grieve’ a variant reading for udkhulū ‘enter’ imperative second person plural has the passive udkhilū ‘they have been admitted’ or dakhalū ‘they entered’; the negation clause ‘no fear shall come upon you nor shall you grieve’ is a circumstantial qualifier in other words they enter Paradise while this is being said to them.

Usama b. Zaid reported that Allah's Messenger (way peace be upon him) said:I stood at the door of Paradise and I found that the overwhelming majority of those who entered therein was that of poor persons and the wealthy persons were detained to get into that. The denizens of Hell were commanded to get into Hell, and I stood upon the door of Fire and the majority amongst them who entered there was that of women

Narrated Abu Sa`id Al-Khudri and Abu Huraira:The Prophet (ﷺ) said, "No fatigue, nor disease, nor sorrow, nor sadness, nor hurt, nor distress befalls a Muslim, even if it were the prick he receives from a thorn, but that Allah expiates some of his sins for that

Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "The example of a believer is that of a fresh tender plant; from whatever direction the wind comes, it bends it, but when the wind becomes quiet, it becomes straight again. Similarly, a believer is afflicted with calamities (but he remains patient till Allah removes his difficulties.) And an impious wicked person is like a pine tree which keeps hard and straight till Allah cuts (breaks) it down when He wishes." (See Hadith No. 558, Vol)

Jabir b. Abdullah reported that Allah's Apostle (ﷺ) happened to walk through the bazar coming from the side of 'Aliya and the people were on both his sides. There he found a dead lamb with very short ears. He took hold of his ear and said:Who amongst you would like to have this for a dirham? They said: We do not like to have it even for less than that as it is of no use to us. He said: Do you wish to have it (free of any cost)? They said: By Allah, even if it were alive (we would not have liked to possess that), for there is defect in it as its ear is very short; now it is dead also. Thereupon Allah's Messenger (ﷺ) said: By Allah, this world is more insignificant in the eye of Allah than it (this dead lamb) is in your eye

Jabir reported Allah's Apostle (ﷺ) narrating a hadith like this with a slight variation of wording

Are psychological and pharmacologic interventions equally effective in the treatment of adult depressive disorders? A meta-analysis of comparative studies.: Objective: A large number of studies suggest that both psychological and pharmacologic therapies are effective in the treatment of mild-to-moderate depressive disorders. Whether both types of intervention are equally effective has not been established definitively. Data sources: A database was developed through a comprehensive literature search (from 1966 to May 2007) in which 6947 abstracts in PubMed (1244 abstracts), PsycINFO (1736), EMBASE (1911), and the Cochrane Central Register of Controll

Adding psychotherapy to pharmacotherapy in the treatment of depressive disorders in adults: a meta-analysis.: Objective: A considerable number of studies has examined whether adding psychotherapy to pharmacotherapy results in stronger effects than pharmacotherapy alone. However, earlier meta-analyses in this field have included only a limited number of available studies and did not conduct extended subgroup analyses to examine possible sources of heterogeneity. Data sources: We used a database derived from a comprehensive literature search in PubMed, PsycINFO, EMBASE, and the Cochrane Central Register o

Efficacy of an adjuvant non-face-to-face multimodal lifestyle modification program for patients with treatment-resistant major depression: A randomized controlled trial.: Background: The high prevalence of depression is partly attributable to the poor response of patients to first-line antidepressants. Multimodal programs that promote a healthy lifestyle are successful in treating depression when used as a complementary therapy, but their medium- and long-term benefits have not been demonstrated for patients with treatment-resistant depression (TRD). The main aim of this study was to compare the effectiveness of a lifestyle modification program (LMP) with mindful

Antidepressant drug effects and depression severity: a patient-level meta-analysis.: Context: Antidepressant medications represent the best established treatment for major depressive disorder, but there is little evidence that they have a specific pharmacological effect relative to pill placebo for patients with less severe depression. Objective: To estimate the relative benefit of medication vs placebo across a wide range of initial symptom severity in patients diagnosed with depression. Data sources: PubMed, PsycINFO, and the Cochrane Library databases were searched from Janua

Interventions to improve return to work in depressed people.: Background: Work disability such as sickness absence is common in people with depression. Objectives: To evaluate the effectiveness of interventions aimed at reducing work disability in employees with depressive disorders. Search methods: We searched CENTRAL (The Cochrane Library), MEDLINE, Embase, CINAHL, and PsycINFO until April 4th 2020. Selection criteria: We included randomised controlled trials (RCTs) and cluster-RCTs of work-directed and clinical interventions for depressed people that in

Identification of depression and anxiety during pregnancy: A systematic review and meta-analysis of test accuracy.: Introduction: Depression and anxiety are significant contributors to maternal perinatal morbidity and a range of negative child outcomes. This systematic review and meta-analysis aimed to review and assess the diagnostic test accuracy of selected screening tools (Edinburgh Postnatal Depression Scale [EPDS], EPDS-3A, Patient Health Questionnaire [PHQ-9]-, PHQ-2, Matthey Generic Mood Question [MGMQ], Generalized Anxiety Disorder scale [GAD-7], GAD-2, and the Whooley questions) used to identify wom

Dietary Nutrient Deficiencies and Risk of Depression (Review Article 2018-2023).

Depression is classified as one of the most common mental disorders. Its prevalence has recently increased, becoming a growing public health threat. This review focuses on clarifying the role and importance of individual nutrients in the diet and the impact of nutrient deficiencies on the risk of depression. Deficiencies in nutrients such as protein, B vitamins, vitamin D, magnesium, zinc, selenium, iron, calcium, and omega-3 fatty acids have a significant impact on brain and nervous system function, which can affect the appearance of depressive symptoms. However, it is important to remember that diet in itself is not the only factor influencing the risk of or helping to treat depression. There are many other aspects, such as physical activity, sleep, stress management, and social support, that also play an important role in maintaining mental health. The data review observed that most o…

Digital Mental Health Interventions for Depression: Scoping Review of User Engagement.

Background: While many digital mental health interventions (DMHIs) have been found to be efficacious, patient engagement with DMHIs has increasingly emerged as a concern for implementation in real-world clinical settings. To address engagement, we must first understand what standard engagement levels are in the context of randomized controlled trials (RCTs) and how these compare with other treatments. Objective: This scoping review aims to examine the state of reporting on intervention engagement in RCTs of mobile app-based interventions intended to treat symptoms of depression. We sought to identify what engagement metrics are and are not routinely reported as well as what the metrics that are reported reflect about standard engagement levels. Methods: We conducted a systematic search of 7 databases to identify studies meeting our eligibility criteria, namely, RCTs that evaluated use of…

Clinicians' Emotional Reactions toward Patients with Depressive Symptoms in Mood Disorders: A Narrative Scoping Review of Empirical Research.

The purpose of this article is to narratively review the empirical literature on clinicians' emotional, cognitive, and behavioral responses (i.e., countertransference) to depressive and other symptoms of patients with mood disorders. Therapist subjective responses (countertransference) can negatively affect both diagnostic and therapeutic processes, especially when they are not recognized and managed promptly. However, at the same time, countertransference recognition, processing, and management can help inform the diagnostic process and improve the therapy process and outcome. In the last couple of decades, the number of studies that empirically explore countertransference toward mood disordered patients, as well as its relationship with various characteristics of both patients and treatment, has increased. Current evidence suggests that patients with depression tend to elicit more posi…

Treatment resistance in psychiatry: state of the art and new directions.

Treatment resistance affects 20-60% of patients with psychiatric disorders; and is associated with increased healthcare burden and costs up to ten-fold higher relative to patients in general. Whilst there has been a recent increase in the proportion of psychiatric research focussing on treatment resistance (R2 = 0.71, p < 0.0001), in absolute terms this is less than 1% of the total output and grossly out of proportion to its prevalence and impact. Here, we provide an overview of treatment resistance, considering its conceptualisation, assessment, epidemiology, impact, and common neurobiological models. We also review new treatments in development and future directions. We identify 23 consensus guidelines on its definition, covering schizophrenia, major depressive disorder, bipolar affective disorder, and obsessive compulsive disorder (OCD). This shows three core components to its definit…

Chronic mild stress paradigm as a rat model of depression: facts, artifacts, and future perspectives.

Rationale: The chronic mild stress (CMS) paradigm was first described almost 40 years ago and has become a widely used model in the search for antidepressant drugs for major depression disorder (MDD). It has resulted in the publication of almost 1700 studies in rats alone. Under the original CMS procedure, the expression of an anhedonic response, a key symptom of depression, was seen as an essential feature of both the model and a depressive state. The prolonged exposure of rodents to unpredictable/uncontrollable mild stressors leads to a reduction in the intake of palatable liquids, behavioral despair, locomotor inhibition, anxiety-like changes, and vegetative (somatic) abnormalities. Many of the CMS studies do not report these patterns of behaviors, and they often fail to include consistent molecular, neuroanatomical, and physiological phenotypes of CMS-exposed animals. Objectives: To …

The Role of the Locus Coeruleus in Pain and Associated Stress-Related Disorders.

The locus coeruleus (LC)-noradrenergic system is the main source of noradrenaline in the central nervous system and is involved intensively in modulating pain and stress-related disorders (e.g., major depressive disorder and anxiety) and in their comorbidity. However, the mechanisms involving the LC that underlie these effects have not been fully elucidated, in part owing to the technical difficulties inherent in exploring such a tiny nucleus. However, novel research tools are now available that have helped redefine the LC system, moving away from the traditional view of LC as a homogeneous structure that exerts a uniform influence on neural activity. Indeed, innovative techniques such as DREADDs (designer receptors exclusively activated by designer drugs) and optogenetics have demonstrated the functional heterogeneity of LC, and novel magnetic resonance imaging applications combined wit…

The Microbiota-Gut-Brain Axis in Psychiatric Disorders.

Modulating the gut microbiome and its influence on human health is the subject of intense research. The gut microbiota could be associated not only with gastroenterological diseases but also with psychiatric disorders. The importance of factors such as stress, mode of delivery, the role of probiotics, circadian clock system, diet, and occupational and environmental exposure in the relationship between the gut microbiota and brain function through bidirectional communication, described as "the microbiome-gut-brain axis", is especially underlined. In this review, we discuss the link between the intestinal microbiome and the brain and host response involving different pathways between the intestinal microbiota and the nervous system (e.g., neurotransmitters, endocrine system, immunological mechanisms, or bacterial metabolites). We review the microbiota alterations and their results in the d…

Role of the Intestinal Microbiome, Intestinal Barrier and Psychobiotics in Depression.

The intestinal microbiota plays an important role in the pathophysiology of depression. As determined, the microbiota influences the shaping and modulation of the functioning of the gut-brain axis. The intestinal microbiota has a significant impact on processes related to neurotransmitter synthesis, the myelination of neurons in the prefrontal cortex, and is also involved in the development of the amygdala and hippocampus. Intestinal bacteria are also a source of vitamins, the deficiency of which is believed to be related to the response to antidepressant therapy and may lead to exacerbation of depressive symptoms. Additionally, it is known that, in periods of excessive activation of stress reactions, the immune system also plays an important role, negatively affecting the tightness of the intestinal barrier and intestinal microflora. In this review, we have summarized the role of the gu…

Anhedonia as a central factor in depression: Neural mechanisms revealed from preclinical to clinical evidence.

Anhedonia is one of the core symptoms of major depressive disorder (MDD), which is often inadequately treated by traditional antidepressants. The modern framework of anhedonia extends the definition from impaired consummatory pleasure or interest in rewards to a broad spectrum of deficits that impact functions such as reward anticipation, approach motivation, effort expenditure, reward valuation, expectation, and reward-cue association learning. Substantial preclinical and clinical research has explored the neural basis of reward deficits in the context of depression, and has implicated mesocorticolimbic reward circuitry comprising the nucleus accumbens, ventral pallidum, ventral tegmental area, amygdala, hippocampus, anterior cingulate, insula, orbitofrontal cortex, and other prefrontal cortex regions. Dopamine modulates several reward facets including anticipation, motivation, effort, …

Sex differences in anxiety and depression: circuits and mechanisms.

Epidemiological sex differences in anxiety disorders and major depression are well characterized. Yet the circuits and mechanisms that contribute to these differences are understudied, because preclinical studies have historically excluded female rodents. This oversight is beginning to be addressed, and recent studies that include male and female rodents are identifying sex differences in neurobiological processes that underlie features of these disorders, including conflict anxiety, fear processing, arousal, social avoidance, learned helplessness and anhedonia. These findings allow us to conceptualize various types of sex differences in the brain, which in turn have broader implications for considering sex as a biological variable. Importantly, comparing the sexes could aid in the discovery of novel therapeutics.

Sleep and Sex: A Review of the Interrelationship of Sleep and Sexuality Disorders in the Female Population, Through the Lens of Sleeping Beauty Syndrome.

Introduction: For many, sleep and sex are crucial for physical, emotional, and mental well-being. Poor sleep quality is linked to a myriad of ailments from coronary artery disease to major depressive disorder. Likewise, a decrease in the frequency of sexual activity is associated with a decrease in self-rated health status. Kleine-Levin syndrome (KLS) is a rare sleep disorder that provides a unique lens to examine the intricate interplay between sleep and sex as it is one of the few sleep disorders defined by concomitant sexual dysfunction. Objectives: This study reviews the literature on links between sleep disorders and sexuality with a focus on women's health followed by a case study of unusual patient with KLS with persistent genital arousal disorder.

Depression and heart failure: the lonely comorbidity.

Depression is a frequent and debilitating comorbidity that affects heart failure (HF) patients. Up to 30% of HF patients suffer from depression and even more have depressive symptoms. Moreover, depression carries a risk for HF, especially in high-risk groups, and is significantly associated with worse quality of life and clinical outcomes. The pathophysiology of depression and HF is poorly understood, but both diseases share several mechanisms and risk factors, including dysregulation of platelet reactivity, inflammation, neuroendocrine function, arrhythmias, high-risk behaviours, and social factors. Current HF guidelines advise to screen HF patients for depression and several screening questionnaires are available. Ultimately, the diagnosis of depression is based on DSM-5 criteria. Depression treatment consists of non-pharmacological and pharmacological therapies. Non-pharmacological th…

Depression-an underrecognized target for prevention of dementia in Alzheimer's disease.

It is broadly acknowledged that the onset of dementia in Alzheimer's disease (AD) may be modifiable by the management of risk factors. While several recent guidelines and multidomain intervention trials on prevention of cognitive decline address lifestyle factors and risk diseases, such as hypertension and diabetes, a special reference to the established risk factor of depression or depressive symptoms is systematically lacking. In this article we review epidemiological studies and biological mechanisms linking depression with AD and cognitive decline. We also emphasize the effects of antidepressive treatment on AD pathology including the molecular effects of antidepressants on neurogenesis, amyloid burden, tau pathology, and inflammation. We advocate moving depression and depressive symptoms into the focus of prevention of cognitive decline and dementia. We constitute that early treatme…

Gender Differences in Depression: Biological, Affective, Cognitive, and Sociocultural Factors.

The odds ratio (OR) for gender differences in major depression is 1.95, averaged meta-analytically over all ages and nations. The gender difference appears by age 12, OR = 2.37, and peaks at OR = 3.02 for ages 13-15. Using the ABC (affective, biological, cognitive) model as a framework within a vulnerability-stress approach, we consider the evidence for biological vulnerabilities (genes, pubertal hormones, and pubertal timing), affective vulnerabilities (temperament), and cognitive vulnerabilities (negative cognitive style, objectified body consciousness, and rumination). The impact of stress is central to the vulnerability-stress model, and we review evidence on gender differences in stress exposure, emphasizing gender differences in sex-related traumas such as child sexual abuse and rape. Finally, we examine sociocultural factors that may contribute to the gender difference, including …

A critical review of current evidence on multiple types of discrimination and mental health.

Little is known about people who experience multiple types of discrimination (e.g., racism and heterosexism). While some work suggests that multiply discriminated groups are at higher risk for poor mental health, other studies propose that they may develop resilience against additional kinds of discrimination. We conducted a review of published studies on the relationship between multiple types of discrimination and mental health to critically examine evidence in support of broad risk and resilience models. Using PRISMA guidelines, we identified 40 studies that met our inclusion criteria. Typically, studies examined either whether experiencing multiple discrimination was related to poorer mental health, or whether one kind of discrimination was more predictive of poor mental health. Studies generally showed support for the risk model, with multiple forms of discrimination associated with…

Role of Interleukin-6 in Depressive Disorder.

Major depressive disorder (MDD), which is a leading psychiatric illness across the world, severely affects quality of life and causes an increased incidence of suicide. Evidence from animal as well as clinical studies have indicated that increased peripheral or central cytokine interleukin-6 (IL-6) levels play an important role in stress reaction and depressive disorder, especially physical disorders comorbid with depression. Increased release of IL-6 in MDD has been found to be a factor associated with MDD prognosis and therapeutic response, and may affect a wide range of depressive symptomatology. However, study results of the IL6 genetic effects in MDD are controversial. Increased IL-6 activity may cause depression through activation of hypothalamic-pituitary-adrenal axis or influence of the neurotransmitter metabolism. The important role of neuroinflammation in MDD pathogenesis has c…

The Psychological Impact of Epidemic and Pandemic Outbreaks on Healthcare Workers: Rapid Review of the Evidence.

Purpose of review: We aim to provide quantitative evidence on the psychological impact of epidemic/pandemic outbreaks (i.e., SARS, MERS, COVID-19, ebola, and influenza A) on healthcare workers (HCWs). Recent findings: Forty-four studies are included in this review. Between 11 and 73.4% of HCWs, mainly including physicians, nurses, and auxiliary staff, reported post-traumatic stress symptoms during outbreaks, with symptoms lasting after 1-3 years in 10-40%. Depressive symptoms are reported in 27.5-50.7%, insomnia symptoms in 34-36.1%, and severe anxiety symptoms in 45%. General psychiatric symptoms during outbreaks have a range comprised between 17.3 and 75.3%; high levels of stress related to working are reported in 18.1 to 80.1%. Several individual and work-related features can be considered risk or protective factors, such as personality characteristics, the level of exposure to affect…

Maternal depressive symptoms and early childhood cognitive development: a review of putative environmental mediators.

Despite the abundance of research investigating the associations between maternal depressive symptoms (MDS) and children's cognitive development, little is known about the putative mechanisms through which depressive symptoms are associated with children's cognitive development. The aim of this review was to summarize the literature on family mediators (i.e., maternal parenting behaviors, mother-child interactions, and family stress) involved in this association in early childhood. The review includes seven studies, five longitudinal and two cross-sectional, which tested putative mediators of the association between MDS and children's cognitive development. Studies were selected from online databases (PubMed, PsycNet) and manual searches. Only studies which quantitatively assessed associations between MDS in the postnatal period and child cognitive development in early childhood (i.e., 0…

Potential Role of Vitamin D for the Management of Depression and Anxiety.

Vitamin D, a fat-soluble vitamin, plays a role not only in calcium and phosphate homeostasis but also in several other functions, including cell growth and neuromuscular and immune function. The deficiency of vitamin D is highly prevalent throughout the world and has been suggested to be associated with an enhanced risk of major depressive disorder (MDD) and anxiety disorders. Therefore, vitamin D supplementation has been investigated for the prevention and treatment of these disorders. This review presents preclinical and clinical evidence of the effects of vitamin D supplementation in these disorders. Although preclinical studies provide limited evidence on the possible mechanisms underlying the beneficial effects of vitamin D for the management of these disorders, most of the clinical studies have indicated that vitamin D supplementation is associated with the reduction of symptoms of…

Sex differences in the neuro-immune consequences of stress: Focus on depression and anxiety.

Women appear to be more vulnerable to the depressogenic effects of inflammation than men. Chronic stress, one of the most pertinent risk factors of depression and anxiety, is known to induce behavioral and affective-like deficits via neuroimmune alterations including activation of the brain's immune cells, pro-inflammatory cytokine expression, and subsequent changes in neurotransmission and synaptic plasticity within stress-related neural circuitry. Despite well-established sexual dimorphisms in the stress response, immunity, and prevalence of stress-linked psychiatric illnesses, much of current research investigating the neuroimmune impact of stress remains exclusively focused on male subjects. We summarize and evaluate here the available data regarding sex differences in the neuro-immune consequences of stress, and some of the physiological factors contributing to these differences. Fu…

Adverse physiological and psychological effects of screen time on children and adolescents: Literature review and case study.

A growing body of literature is associating excessive and addictive use of digital media with physical, psychological, social and neurological adverse consequences. Research is focusing more on mobile devices use, and studies suggest that duration, content, after-dark-use, media type and the number of devices are key components determining screen time effects. Physical health effects: excessive screen time is associated with poor sleep and risk factors for cardiovascular diseases such as high blood pressure, obesity, low HDL cholesterol, poor stress regulation (high sympathetic arousal and cortisol dysregulation), and Insulin Resistance. Other physical health consequences include impaired vision and reduced bone density. Psychological effects: internalizing and externalizing behavior is related to poor sleep. Depressive symptoms and suicidal are associated to screen time induced poor sle…

Inflammation and depression: a causal or coincidental link to the pathophysiology?

This review summarises the evidence that chronic low grade inflammation triggers changes that contribute to the mental and physical ill health of patients with major depression. Inflammation, and the activation of the hypothalamic pituitary axis by stress, are normal components of the stress response but when stress is prolonged and the endocrine and immune system become chronic resulting in the activation of the peripheral macrophages, the central microglia and hypercortisolemia, the neuronal networks are damaged and become dysfunctional. The proinflammatory cytokines, in addition to activating the hypothalamic-pituitary-adrenal axis and thereby increasing cortisol synthesis, also activate the tryptophan-kynurenine pathway. This results in the synthesis of the neurotoxic N-methyl-d-aspartate (NMDA) glutamate agonist quinolinic acid and 3-hydroxykynurenine thereby enhancing oxidative str…

Neural basis of major depressive disorder: Beyond monoamine hypothesis.

The monoamine hypothesis has been accepted as the most common hypothesis of major depressive disorder (MDD) for a long period because of its simplicity and understandability. Actually, most currently used antidepressants have been considered to act based on the monoamine hypothesis. However, an important problem of the monoamine hypothesis has been pointed out as follows: it fails to explain the latency of response to antidepressants. In addition, many patients with MDD have remained refractory to currently used antidepressants. Therefore, monoamine-alternate hypotheses are required to explain the latency of response to antidepressants. Such hypotheses have been expected to contribute to identifying hopeful new therapeutic targets for MDD. Past studies have revealed that the volume of the hippocampus is decreased in patients with MDD, which is likely caused by the failure of the hypothal…

Gut Microbiota, Bacterial Translocation, and Interactions with Diet: Pathophysiological Links between Major Depressive Disorder and Non-Communicable Medical Comorbidities.

Background: Persistent low-grade immune-inflammatory processes, oxidative and nitrosative stress (O&NS), and hypothalamic-pituitary-adrenal axis activation are integral to the pathophysiology of major depressive disorder (MDD). The microbiome, intestinal compositional changes, and resultant bacterial translocation add a new element to the bidirectional interactions of the gut-brain axis; new evidence implicates these pathways in the patho-aetiology of MDD. In addition, abnormalities in the gut-brain axis are associated with several chronic non-communicable disorders, which frequently co-occur in individuals with MDD, including but not limited to irritable bowel syndrome (IBS), chronic fatigue syndrome (CFS), obesity, and type 2 diabetes mellitus (T2DM). Methods: We searched the PubMed/MEDLINE database up until May 1, 2016 for studies which investigated intestinal dysbiosis and bacterial …

Vagal Nerve Stimulation for Treatment-Resistant Depression.

Major depressive disorder (MDD) is prevalent. Although standards antidepressants are more effective than placebo, up to 35% of patients do not respond to 4 or more conventional treatments and are considered to have treatment-resistant depression (TRD). Considerable effort has been devoted to trying to find effective treatments for TRD. This review focuses on vagus nerve stimulation (VNS), approved for TRD in 2005 by the Food and Drugs Administration. Stimulation is carried by bipolar electrodes on the left cervical vagus nerve, which are attached to an implanted stimulator generator. The vagus bundle contains about 80% of afferent fibers terminating in the medulla, from which there are projections to many areas of brain, including the limbic forebrain. Various types of brain imaging studies reveal widespread functional effects in brain after either acute or chronic VNS. Although more ran…
