Depression research, explained
17 open-access depression studies, each with a flashcard deck and a quiz.
- Does astrocyte pyroptosis help explain stress depression in mice?
In a mouse chronic-mild-stress model, hippocampal astrocytes died by NLRP3/caspase-1/GSDMD pyroptosis; knocking out that cascade (or giving an SSRI) eased depression-like behavior, while putting GSDMD-N back in astrocytes wiped out the benefit.
- Can a gut antibiotic ease stress depression in adolescent rats?
In 56 adolescent rats, 150 mg/kg rifaximin during 4 weeks of CUMS restored sucrose preference, open-field and water-maze performance, raised Ruminococcaceae/Lachnospiraceae and brain butyrate, and shifted microglia toward anti-inflammatory functions.
- Does saying 'I' more often link to depression and anxiety?
Using first-person singular pronouns while remembering sad events is linked to higher anxiety and depression in healthy individuals and those with eating disorders, but not in clinically depressed patients.
- Do thinking problems in first-time depression outlast the low mood?
A year after their first depressive episode, most patients had largely recovered from their symptoms but still did worse than matched controls at suppressing automatic responses and at naming words from a category.
- Can an Online Program Help Prevent Postpartum Depression?
An online cognitive behavioral therapy program successfully reduced depressive symptoms by helping at-risk mothers improve their self-compassion and emotion regulation skills.
- How does brain activity during body awareness relate to alexithymia?
Healthy people with difficulty describing emotions show altered brain activity during body-awareness tasks, a pattern that is disrupted in individuals with major depression.
- How do people with unexplained symptoms perceive their bodies?
People with unexplained physical symptoms do not detect bodily signals more intensely, but they struggle more with worrying, ignoring, and trusting their physical sensations.
- Can an action video game help people with depression?
Depressed patients who played a fast action video game for six weeks reported less rumination and better thinking than a wait-list group, but their depression scores did not change and the effects were fragile.
- Do the benefits of metacognitive therapy for depression last?
Three years after just 10 sessions of metacognitive therapy, most depressed patients were still recovered and many had moved off benefits and back into work, though there was no comparison group at follow-up.
- Can computer programs find signs of depression in our speech?
Computerized analysis of brief speech samples revealed that people with depression use more negative words, more past tense, fewer prepositions, and fewer words expressing uncertainty compared to healthy individuals.
- Do people with dysphoria feel less daily pleasure?
In daily life, college students with dysphoria experience less pleasure both when anticipating upcoming events and during actual activities compared to healthy peers, though they do not differ on traditional trait-level surveys.
- How depression affects emotional voice and word perception
People with depression perceive positive words and positive vocal tones as less emotionally intense than healthy individuals do.
- Is cognitive control in depression linked to serotonin receptors?
People with major depressive disorder who have fewer 5-HT1A serotonin receptors show worse cognitive control and altered brain activity during impulse-control tasks.
- How does depression affect how we tell our feelings apart?
People with both active and recovered depression have a harder time distinguishing between different negative and positive feelings compared to healthy individuals.
- Can hidden 'stay calm' words help depressed people hold back responses?
Flashing emotion-control words too briefly to be seen made people with depression better at withholding responses to emotional faces, but did not change healthy people's performance.
- How does metacognitive training ease depression in older adults?
For older adults with depression, a group metacognitive training programme reduced rumination and negative beliefs more than a brain-training control, and these changes statistically accounted for later improvements, though which one mattered depended on who rated the depression.
- Do people with depressive symptoms learn fear less well?
Students with mild-to-higher depressive symptoms did not show a learned fear response in their skin conductance, even though they reported knowing which shape predicted a shock.
