Depression treatment responses vary widely among individuals. Identifying objective biomarkers with predictive accuracy for therapeutic outcomes can enhance treatment efficiency and avoid ineffective therapies. This study investigates whether functional near-infrared spectroscopy (fNIRS) and clinical assessment information can predict treatment response in major depressive disorder (MDD) through machine-learning techniques. Seventy patients with MDD were included in… Continue reading Application of functional near-infrared spectroscopy and #machine learning to predict treatment response after six months in major #depressive disorder

Adaptive #cognitive control circuit changes associated with problem-solving ability and #depression symptom outcomes over 24 months
Behavioral intervention therapies can improve symptoms of depression but do not work for all patients. To identify brain circuit changes that might underlie treatment response, Zhang et al. performed a longitudinal fMRI imaging study on patients with depression and comorbid obesity who received either problem-solving therapy (I-CARE) or usual care (U-CARE). They found that decreased cognitive… Continue reading Adaptive #cognitive control circuit changes associated with problem-solving ability and #depression symptom outcomes over 24 months
Clinical #EEG slowing induced by electroconvulsive therapy is better described by increased frontal aperiodic activity
Electroconvulsive therapy (ECT) is one of the most efficacious interventions for treatment-resistant depression. Despite its efficacy, ECT’s neural mechanism of action remains unknown. Although ECT has been associated with “slowing” in the electroencephalogram (EEG), how this change relates to clinical improvement is unresolved. Until now, increases in slow-frequency power have been assumed to indicate increases… Continue reading Clinical #EEG slowing induced by electroconvulsive therapy is better described by increased frontal aperiodic activity
The predictive validity of a #Brain Care Score for late-life #depression and a composite outcome of #dementia, #stroke, and late-life #depression: data from the UK Biobank cohort
Introduction: The 21-point Brain Care Score (BCS) is a novel tool designed to motivate individuals and care providers to take action to reduce the risk of stroke and dementia by encouraging lifestyle changes. Given that late-life depression is increasingly recognized to share risk factors with stroke and dementia, and is an important clinical endpoint for brain… Continue reading The predictive validity of a #Brain Care Score for late-life #depression and a composite outcome of #dementia, #stroke, and late-life #depression: data from the UK Biobank cohort
Personalized brain circuit scores identify clinically distinct biotypes in #depression and #anxiety
There is an urgent need to derive quantitative measures based on coherent neurobiological dysfunctions or ‘biotypes’ to enable stratification of patients with depression and anxiety. We used task-free and task-evoked data from a standardized functional magnetic resonance imaging protocol conducted across multiple studies in patients with depression and anxiety when treatment free (n = 801) and after… Continue reading Personalized brain circuit scores identify clinically distinct biotypes in #depression and #anxiety
Long-term exposure to residential #greenness and decreased risk of #depression and #anxiety
Residential greenness is considered a unique and potentially modifiable exposure construct to reduce physiological stress and improve human health. Here this study aims to investigate the longitudinal relationships of residential greenness with incident depression and anxiety and to explore and compare the pathways in which greenery may influence mental health. After excluding participants with depression… Continue reading Long-term exposure to residential #greenness and decreased risk of #depression and #anxiety
Adherence to #Mediterranean diet is inversely associated with #depressive symptoms in older women: findings from the NutBrain Study
Data on the association of the Mediterranean diet with depressive symptoms in older people at high risk of depression are scarce. This study aimed to investigate the cross-sectional association of the adherence to the Mediterranean diet and its components with depressive symptoms in the Italian NutBrain cohort of older men and women. A total of… Continue reading Adherence to #Mediterranean diet is inversely associated with #depressive symptoms in older women: findings from the NutBrain Study
Most #GLP-1 Medications Correlated with a Lower Likelihood of #Anxiety and #Depression Diagnoses
Key FindingsDiabetic patients prescribed tirzepatide, semaglutide, dulaglutide, and exenatide are less likely to be diagnosed with depression after starting the medication compared to those not on a glucagon-like peptide-1 receptor agonist (GLP-1) medication. The likelihood of anxiety in diabetic patients is lower for those on all five GLP-1 medications studied. Among non-diabetic patients, semaglutide is correlated with… Continue reading Most #GLP-1 Medications Correlated with a Lower Likelihood of #Anxiety and #Depression Diagnoses
Elevated body #temperature is associated with #depressive symptoms: results from the TemPredict Study
Correlations between altered body temperature and depression have been reported in small samples; greater confidence in these associations would provide a rationale for further examining potential mechanisms of depression related to body temperature regulation. We sought to test the hypotheses that greater depression symptom severity is associated with (1) higher body temperature, (2) smaller differences… Continue reading Elevated body #temperature is associated with #depressive symptoms: results from the TemPredict Study
