the role of antidepressant treatments on cognitive deficits: a review of recent literature
2011
Objective: Nowadays, the interaction between cognition and emotions during a depressive disorder in an area of interest in the scientific literature. Patients with major depressive disorder (MDD) usually show alterations in various cognitive functions: attention, working memory, mental processing speed, executive functions. Clinical observation of the effects of cognitive deficits on quality of life in patients with MDD, in euthymic and relapse phases, needs a review of recent scientific literature on the impact of antidepressant treatment as a protective factor of the improvement of cognitive performances. Methods: Electronic PubMed and PsycInfo searches were conducted to identify research…
Linoleic acid: Is this the key that unlocks the quantum brain? Insights linking broken symmetries in molecular biology, mood disorders and personalis…

Abstract In this paper we present a mechanistic model that integrates subneuronal structures, namely ion channels, membrane fatty acids, lipid rafts, G proteins and the cytoskeleton in a dynamic system that is finely tuned in a healthy brain. We also argue that subtle changes in the composition of the membrane’s fatty acids may lead to down-stream effects causing dysregulation of the membrane, cytoskeleton and their interface. Such exquisite sensitivity to minor changes is known to occur in physical systems undergoing phase transitions, the simplest and most studied of them is the so-called Ising model, which exhibits a phase transition at a finite temperature between an ordered and disorde…
Associations of neuropsychiatric symptoms and antidepressant prescription with survival in Alzheimer's disease
2017
Objective Depression is associated with increased mortality in community samples. The use of antidepressant medication may also increase mortality, however, it is still unclear whether taking antidepressants before or after a diagnosis of dementia influences survival. Design Retrospective. Setting A cohort with a diagnosis of Alzheimer disease (AD) from a large mental health and dementia care database in South London, linked to hospitalization and mortality data. Participants Mild dementia (Mini-Mental State Examination ≥18/30) at the point of diagnosis. Measurements We ascertained antidepressant prescription, either in the 6 months before or after dementia diagnosis, and used the HoNOS65+,…
Common genes associated with antidepressant response in mouse and man identify key role of glucocorticoid receptor sensitivity.
2017
Response to antidepressant treatment in major depressive disorder (MDD) cannot be predicted currently, leading to uncertainty in medication selection, increasing costs, and prolonged suffering for many patients. Despite tremendous efforts in identifying response-associated genes in large genome-wide association studies, the results have been fairly modest, underlining the need to establish conceptually novel strategies. For the identification of transcriptome signatures that can distinguish between treatment responders and nonresponders, we herein submit a novel animal experimental approach focusing on extreme phenotypes. We utilized the large variance in response to antidepressant treatmen…
