Effect of sleep quality on repetitive transcranial magnetic stimulation outcomes in depression.

Front Psychiatry

September 2024

Brain Stimulation Mechanisms Laboratory, Division of Depression and Anxiety Disorders, McLean Hospital, Belmont, MA, United States.

Introduction: While repetitive transcranial magnetic stimulation (rTMS) is effective for 50-60% of those treatment-resistant depression, it is critical to identify predictors of response for optimal patient selection to improve therapy. Insomnia is a known symptom of depression that is both correlated with depression severity and associated with poor antidepressant response. Therefore, understanding this relationship may open new opportunities for the optimization of rTMS treatment.

This study investigates (a) age-related differences in how the intensity of stereotyped facial expressions influence the emotion label children, adolescents, and adults assign to that face and (b) how this perceptual sensitivity relates to subclinical symptoms of psychopathology. In 2015-2016, 184 participants aged 4-25 years viewed posed stereotypes of angry, fearful, sad, and happy expressions morphed with neutral expressions at 10%-90% intensity. Thin plate regression smoothing splines were used to chart nonlinear associations between age and the perceptual threshold participants needed to assign the emotion label expected based on cultural consensus.

Article Synopsis
  • Researchers aimed to create and validate Methylation Risk Scores (MRS) using machine learning to identify individuals at risk for PTSD based on genomic and trauma exposure data.
  • The study developed three models: eMRS (which combines trauma exposure and methylation data), MoRS (which relies only on methylation data), and MoRSAE (which adjusts MoRS for trauma exposure).
  • The eMRS model showed the best performance with a 92% accuracy, and all models were able to predict post-deployment PTSD significantly, suggesting that including trauma exposure improves risk assessment.

Hyperstable arousal regulation during a 15-min resting electroencephalogram (EEG) has been linked to a favorable response to antidepressants. The EMBARC study, a multicenter randomized placebo-controlled clinical trial, provides an opportunity to examine arousal stability as putative antidepressant response predictor in short EEG recordings. We tested the hypothesis that high arousal stability during a 2-min resting EEG at baseline is related to better outcome in the sertraline arm and explored the specificity of this effect.

Background: Major Depressive Disorder (MDD) is a heterogenous and etiologically complex disease often presenting with divergent appetitive phenotypes including Hyperphagic MDD (characterized by an increased appetite) and Hypophagic MDD (characterized by a decrease in appetite) which are closely related to comorbidities, including cardiometabolic disorders. Hyperphagia is associated with atypical depression, decreased stress-hormone signaling, a pro-inflammatory status, hypersomnia, and poorer clinical outcomes. Yet, our understanding of associated biological correlates of Hyperphagic and Hypophagic MDD remain fragmented.

Article Synopsis
  • Individuals with schizophrenia (SCZ) show altered sleep patterns, particularly in NREM sleep, with group-level differences seen in EEG metrics like spindles and slow oscillations compared to controls.
  • A study involving 103 SCZ patients and 68 controls confirmed these differences and revealed significant variability in sleep metrics among SCZ patients, suggesting individual differences beyond clinical factors are present.
  • The research indicated that medication regimens, especially olanzapine, significantly contribute to this variability and highlighted exaggerated age-related effects on certain sleep metrics in SCZ patients, raising concerns about biological aging and potential medication side effects.

Ketamine for refractory depression: Save the best for last?

J Psychopharmacol

September 2024

Department of Psychiatry, McLean Hospital, Belmont, MA, USA.

Ketamine has recently been shown to be non-inferior to electroconvulsive therapy (ECT), one of psychiatry's most effective treatments for depression. Given the novelty of ketamine as well as its interventional nature, ketamine is currently viewed as an alternative to ECT and as such, considered a third-line agent for treatment-refractory depression. However, available data suggest that ketamine carries a low side-effect burden and is better tolerated than many second-line augmentation strategies for depression.

Background: Aberrant functional connectivity is a hallmark of schizophrenia. The precise nature and mechanism of dysconnectivity in schizophrenia remains unclear, but evidence suggests that dysconnectivity is different in wake versus sleep. Microstate analysis uses electroencephalography (EEG) to investigate large-scale patterns of coordinated brain activity by clustering EEG data into a small set of recurring spatial patterns, or microstates.

Article Synopsis
  • Chronic posttraumatic pain (CPTP) is prevalent after traumatic stress exposure (TSE), especially in women, and higher levels of 17β-estradiol (E2) during the traumatic event are linked to lower CPTP risks in women.
  • In a study involving 543 samples, researchers found a significant negative relationship between peritraumatic E2 levels and subsequent CPTP in women but not in men.
  • An animal study revealed that administering E2 immediately after TSE in female rats helped prevent mechanical hypersensitivity, suggesting that timely E2 treatment could be a potential therapeutic approach for women at risk of developing CPTP.
