Introduction: Depression represents a public health issue because it significantly increases the risk of disabilities and premature mortality, decreases the quality of life, and increases the costs of care. The incomplete remissions favor the aggravation of neurobiological dysfunctions and pathogenesis of severe somatic comorbidities. The etiopathogenic mechanisms of depression are complex and involve multisystemic risk factors (genetic, neuroanatomic, neurobiochemical, neuroendocrine and psychosocial).

Introduction: Atypical antipsychotics have numerous benefits compared to conventional ones in respect to the possible adverse effects. However, like the other ones, they may induce direct cardiovascular alterations, probably through the apoptotic effect of dopamine receptor D2 (DRD2) blockade. The main objective of the study was to assess the cardiac ejection fraction (EF) using transthoracic speckle tracking echocardiography (TSTE) in patients treated with long-acting injectable (LAI) atypical antipsychotics.

Patients with serious mental illness are a high-risk category of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Patients with schizophrenia are not participatory and have increased mortality and morbidity, patients with dementia cannot be cared for while depression, anxiety, bipolar tubing are associated with low immune status. Social stress is amplified by social isolation, amplifying depression and the mechanisms of decreased immunity.

In recent decades, traumatic brain injury (TBI) has become one of the most important health problems worldwide and is a major cause of morbidity, mortality and economic losses. Mild traumatic brain injury (mTBI) is less considered, with clinical underestimation leading to an epidemiological underevaluation of its incidence. Many of the signs and symptoms induced by mTBI are difficult to highlight clinically, especially those related to cognitive, behavioral, or emotional impairment.

Objective: The present placebo-controlled study evaluated the efficacy and safety of 8 weeks of treatment with tianeptine 25-50 mg/d in elderly patients suffering from major depressive disorder (MDD) according to DSM-IV-TR. Escitalopram 5-10 mg/d was used as an active comparator.

Methods: Elderly outpatients aged at least 65 years with a primary diagnosis of moderate to severe episode of recurrent MDD were recruited by psychiatrists in 44 clinical centers in 10 countries from October 2013 to January 2016.

Incidence of Alzheimer's disease (AD) in people over 75 years is much higher, and the progression of cognitive deficit become faster, leading to a decrease of quality of life for patients and their families. In this context, it is proposed a multifactorial pathogenic model of disconnected cognitive circuits, which is combined with genetic and vascular-cerebral vulnerability elements, allowing an aggressive progression of neurodegenerative factors, favoring onset of dementia. Data from research studies on animal model (rat) highlighted central role of cerebral cholinergic deficit (which is amplified by cerebral ischemia) on the background of apolipoprotein E4 (ApoE4) genotype, favoring multifactorial disconnected mechanisms, by excess of beta-amyloid (β-A) or increase of vascular dysfunction.

Introduction: Schizophrenia is the most severe psychiatric illness, with a biological support in the brain. There is evidence that the adequate dopamine balance in the frontal cortex is associated with a better outcome of the disorder, while the alteration of dopamine mechanism at this level may affect the vascular system leading to secondary neuronal alterations. Our study was conducted post-mortem and its objective was to identify the alterations in the neuronal architecture, in the integrity of the microvascular unit in the frontal cortex of patients treated with potent and excessive D2-blocking antipsychotics.
