Processing speed was the cognitive function most often affected by depression, with a slower capability when individuals are depressed.
A longitudinal study found that pregnant mothers who experience depression are four times more likely to have children exhibiting violent behavior at age 16. The study suggests a link between maternal depression during pregnancy and increased antisocial behavior in children, with no apparent influence from family environment factors.

A meta-analysis of randomized trials found that antidepressant medications provide substantial benefit for patients with very severe depression, but little to no benefit for those with mild or moderate symptoms. The study suggests that the efficacy of these medications largely depends on the severity of depression symptoms.
A study found that many Americans with major depression do not receive adequate treatment, with racial and ethnic groups facing disparities. Psychotherapy is more commonly used than pharmacotherapy, but individuals with specific ethnic backgrounds have lower odds of receiving concordant care.

Researchers pinpointed prime factors identifying elderly persons at high risk for developing major depression, including low-level depressive symptoms and poor social support. Preventive treatments hold promise for providing the greatest health benefit at the lowest cost.
A new study found that physical activity increases self-efficacy, which in turn reduces disease-related depression and fatigue. Higher levels of physical activity correspond to higher self-efficacy and lower levels of depression and fatigue, but the effect is reduced when controlling for self-efficacy.
Researchers found that anxiety sensitivity significantly predicted depression symptoms in above-average worriers. The fear of cognitive dyscontrol and publically observable anxiety symptoms specifically correlated with depression. Understanding this link may lead to new depression treatments by addressing anxiety sensitivity.
Researchers found that depressed women had no significant difference in weight loss success compared to non-depressed women. The key factor was attendance at a minimum of 12 sessions, regardless of depression status.
Researchers found that children whose mothers had more depressive symptoms experienced more frequent asthma symptoms, while those with fewer depressive symptoms had less frequent symptoms. The study suggests maternal depression is an independent risk factor for childhood asthma symptoms.

Depression following stroke is a significant public health problem affecting one-third of patients.
Research suggests preschool depression is a continuous, chronic condition that increases the likelihood of subsequent depression and psychiatric disorders. Early intervention during the preschool period may be crucial in addressing childhood major depressive disorder.
