The consumption of a high-fat diet (HFD) and obesity have been associated not only with metabolic diseases but also with neuropsychiatric diseases, such as depression and anxiety. However, results on the effects of an HFD on anxiety are controversial, since both anxiogenic and anxiolytic effects have been reported. In this study, we evaluated the effects of both short- and long-term intake of an HFD on anxiety-like behaviors. To explore the impact of time on the association between an HFD and anxiety, mice were fed with an HFD for 4 weeks or 12 weeks...

Acute or chronic exposure to stress can increase the risk to develop major depressive disorder, a severe, recurrent and common psychiatric condition. Depression places an enormous social and financial burden on modern society. Although many depressed patients are treated with antidepressants, their efficacy is only modest, underscoring the necessity to develop clinically-effective pharmaceutical or behavioral treatments. Exercise training produces beneficial effects on stress-related mental disorders, indicative of clinical potential...

Major depressive disorder (MDD) is a chronic condition that affects one in six adults in the US during their lifetime. The current practice of antidepressant medication prescription is a trial-and-error process. Additionally, over a third of patients with MDD fail to respond to two or more antidepressant treatments. There are no valid clinical markers to personalize currently available antidepressant medications, all of which have similar mechanisms targeting monoamine neurotransmission. The goal of this review is to summarize the recent findings of immune dysfunction in patients with MDD, the utility of inflammatory markers to personalize treatment selection, and the potential of targeting inflammation to develop novel antidepressant treatments...

Depressive disorder is a mental health disorder caused by the dysfunction of nerve regeneration, neuroendocrine and neurobiochemistry, which frequently results in cognitive impairments and disorder. Evidence has shown that resveratrol offers benefits for the treatment of depressive disorder. In the present study, the therapeutic effects of resveratrol were investigated and the potential mechanisms mediated by resveratrol were analyzed in hippocampal neuron cells. The anti‑oxidative stress and anti‑inflammatory properties of resveratrol were also examined in vitro and in vivo...

Activation of immune-inflammatory and oxidative-nitrosative (IO&NS) stress pathways plays a role in major depression (MDD). Evidence suggests that curcumin (500-1000 mg/day), a polyphenol with strong anti-IO&NS properties, may have efficacy either as monotherapy or as an adjunctive treatment for depression. Further controlled trials with extended treatment periods (> 8 weeks) and higher curcumin doses are warranted. This 12-week study was carried out to examine the effects of adjunctive curcumin for the treatment of MDD...

Brain photobiomodulation (PBM) therapy using red to near-infrared (NIR) light is an innovative treatment for a wide range of neurological and psychological conditions. Red/NIR light is able to stimulate complex IV of the mitochondrial respiratory chain (cytochrome c oxidase) and increase ATP synthesis. Moreover, light absorption by ion channels results in release of Ca2+ and leads to activation of transcription factors and gene expression. Brain PBM therapy enhances the metabolic capacity of neurons and stimulates anti-inflammatory, anti-apoptotic, and antioxidant responses, as well as neurogenesis and synaptogenesis...

In our previous study, we found that the edible alcohol extract of the root of the medicinal plant Rhodiola crenulata (RCE) improved spatial cognition in a rat model of Alzheimer's disease. Another study from our laboratory showed that RCE enhanced neural cell proliferation in the dentate gyrus of the hippocampus and prevented damage to hippocampal neurons in a rat model of chronic stress-induced depression. However, the mechanisms underlying the neuroprotective effects of RCE are unclear. In the present study, we investigated the anti-apoptotic effect of RCE and its neuroprotective mechanism of action in a rat model of Alzheimer's disease established by intracerebroventricular injection of streptozotocin...

The functions of n-3 fatty acids are known to be diverse, and they play roles in cardiovascular and neuronal systems and in lipid metabolism. Docosahexaenoic acid (DHA), which is the most abundant n-3 fatty acid in the brain, is essential for the maintenance of brain functions throughout the human lifespan. Epidemiological studies have demonstrated that reduced n-3 fatty acid intake is closely associated with the onset of mental and neurological diseases such as brain developmental disorders, depression, and Alzheimer's disease...

Atopic dermatitis (AD) is an inflammatory disorder of the skin characterized by an impaired immune response and skin barrier function. It is very frequent in adult population being present in up to 10% of population. Quality of life is often reduced in AD patients due to disease burden and symptoms like itch. AD is also frequently associated with psychological diseases such as anxiety or depression. Due to its chronic nature and severity of presentation AD often may not respond to topical treatment and requires systemic treatments which can be associated with significant side effects...

BACKGROUND: The prevalence of anxiety and depression is significantly higher in individuals with psoriasis than in the general population. Clinical data also show that anti-anxiety and antidepression drugs can reduce skin lesions in patients with psoriasis, but the actual mechanism is still poorly understood. AIM: To investigate whether brain-derived neurotrophic factor (BDNF) and tropomyosin receptor kinase B (TrKB) signalling plays a role in the mechanism underlying psoriasis with depression and anxiety behaviours...

Alzheimer's disease (AD), a complex chronic progressive central nervous system degenerative disease and a public health problem of the world, often characters cognitive dysfunction accompaning aggression and depression, and may lead to death. More attentions should be paid on it because there is no modified strategy against AD till now. AD is featured with the loss of cholinergic neurons, the amyloid-beta peptide (Aβ) plaques and the neurofibrillary tangles and several hypotheses were established to explain the pathogenesis of AD...

Heterogeneity in response to conventional antidepressants is a well-recognized limitation of evidence-based pharmacological treatments of major depressive disorder (MDD). Abnormal activation of inflammatory pathways is postulated as one likely mechanism contributing to treatment resistance in MDD. In a subset of depressed patients, the balance between pro- and anti-inflammatory cytokines is thought to be altered, causing mood symptoms due to inflammation, as seen in co-morbid depression associated with inflammatory conditions (e...

Cerebral ischemia because of vertebrobasilar insufficiency (VBI) rarely presents as an initial sign within the systemic lupus erythematosus (SLE) population, and there are very few case reports supporting this manifestation. This report details 3 different patients with SLE who experienced VBI as an initial manifestation. Patient 1 was a 24-year-old female who developed a bilateral pontine lesion as a consequence of basilar artery stenosis. Patient 2 was a 34-year-old male with an acute ischemic lesion on the right side of his cerebellum and pons because of significant stenosis in the distal segment of the right vertebral artery...

RATIONALE: Evidence indicates that ketamine's rapid antidepressant efficacy likely results from its antagonism of NR2B-subunit-containing NMDA receptors (NMDAR). Since ketamine equally blocks NR2A- and NR2B-containing NMDAR, and has affinity to other receptors, NR2B-selective drugs might have improved therapeutic efficiency and side effect profile. OBJECTIVES: We aimed to compare the effects of (S)-ketamine and two different types of NR2B-selective antagonists on functional brain networks in rats, in order to find common circuits, where their effects intersect, and that might explain their antidepressant action...
