A multicenter study published in Depression and Anxiety found that mecamylamine, a nicotine antagonist, significantly improved behavioral and emotional symptoms in children co-diagnosed with Tourette's syndrome and major depression. The study suggested that mecamylamine stabilizes mood by inhibiting nicotinic receptors.
A study found a common genetic link between depression and cardiovascular disease, with increased frequency of specific gene variants in patients with severe depression.

Researchers at the University of California - Irvine have discovered two new compounds, URB532 and URB597, that relieve anxiety by inhibiting the breakdown of natural neurotransmitters, similar to Prozac. These gentler biochemical approaches may lead to more effective and side-effect-free treatments for anxiety and depression.
A recent study published in Psychosomatic Medicine found that depression is more deadly for men over 70 than women, despite occurring less frequently. Depression was associated with increased mortality rates in men after accounting for other factors, while chronic and remitted depression had no significant impact on mortality rates.
A study of 39 hepatitis C patients found that 33% developed interferon-induced major depression, but 84% improved with antidepressant treatment. The research challenges the common practice of discontinuing interferon therapy for depressed patients.

The finding could lead to more targeted treatments and help identify family members at risk before they experience a major depression.

Chronic Prozac treatment was found to be effective in protecting females from the negative effects of stressful experiences on learning. The researchers also found that males and females respond differently to stressful experiences.

This discovery suggests important differences in the molecular basis of clinical depression between sexes, which may contribute to varying treatment responses and symptoms.
A computer-based system is being developed to assist astronauts on extended missions with conflict resolution and mild depression. The system uses problem-solving therapy and computer simulations to help users identify and address problems.

Researchers investigate how reducing serotonin levels affects people with and without depression. The study uses tryptophan depletion to temporarily lower serotonin levels in participants, aiming to discover new ways to predict who is at risk for major depression and when treatment can be safely discontinued.
Researchers have found that people with depression have a persistent biological abnormality in their serotonin systems, even when not depressed. The study, published in Neuropsychopharmacology, suggests depression reflects a genetic trait and may require longer medication use.
In a study involving 495 patients, Effexor XR showed significantly higher remission rates compared to placebo. At the end of 12 months, 67% of patients maintained remission after a year of therapy, with 46% on placebo.
Duke University researchers found depression to be a significant predictor of worse quality of life and perceived shortness of breath in patients awaiting lung transplantation. The study suggests that treating depression could improve outcomes after lung transplantation, which could benefit patients with severe lung disease like COPD.
The Stanford study found that the quality of care received by depressed patients has significantly improved since the introduction of selective serotonin reuptake inhibitors (SSRIs) in 1988. The study also revealed a notable increase in physician visits for depression, largely driven by the adoption of SSRIs.
Two studies found that hungry children are more likely to experience depression and suicidal thoughts, as well as lower academic performance. One study analyzed data from over 700 adolescents and found those living in food-insecure households were five times more likely to attempt suicide.
Researchers found nicotine shows promise as an antidepressant in a Wistar-Kyoto rat model of depression. The study suggests that nicotine or nicotinic agonists could be therapeutic options for treating depressive illnesses. However, the risks associated with cigarette smoking outweigh any potential benefits.
A study found that patients with depression experience lower disease improvement rates (4.7%) compared to mentally healthy patients (7.4%). Depressed individuals may be more likely to continue smoking and have impaired immune systems, leading to slower wound healing and poorer treatment outcomes.
A large clinical trial found St. John's wort to be no more effective than placebo in treating moderately severe major depression. Researchers tested the supplement against the antidepressant sertraline and concluded that patients with moderate to severe depression should not self-medicate with St. John's wort.
A study suggests that a high intake of DHA may reduce the risk of postpartum depression. Babies who receive sufficient levels of DHA also benefit from improved neurological development. The American Chemical Society research aims to raise awareness about the importance of nutrition for mothers and their babies.
A study by Pitt researchers found that men and women have different genetic markers associated with severe depression, which may lead to better diagnosis and treatment strategies. The findings suggest that sex-specific genes for recurrent major depression may be the rule rather than the exception.
A recent study found that postpartum fatigue is significantly linked to postpartum depression, with women reporting symptoms after just 28 days, highlighting the need for screening tools and self-care support
A team of researchers is tracking the health of rescue dogs and their handlers who searched at the World Trade Center and Pentagon. The study aims to identify potential long-term consequences, including cancer and mental health issues, and provide assistance to those affected.

Researchers found that cancer patients tend to lower their expectations to match their reality, leading to decreased anxiety and depression. However, spouses of cancer patients experienced increased anxiety and depression due to unchanging life values and care-taking responsibilities.
A genetic study found that a polymorphism in the serotonin transporter promoter region is associated with mood response during tryptophan depletion, indicating a potential link between diet and depression relapse. The study suggests that individual genetic differences may influence the impact of dietary changes on depressive symptoms.
A systematic review of prison populations in 12 Western countries found that prisoners were two to four times more likely to have psychosis and major depression, and about ten times more likely to have antisocial personality disorder. This suggests that mental health issues among prisoners may require increased attention and treatment.
A study of 78 older adults found that chronic, sub-clinical mild depression can suppress immune systems, leading to poorer responses to infections and diseases. The findings suggest that early detection and treatment of even mild depression may be crucial for better health in older adults.
A recent study found that depression treatments are less effective among certain populations, including elderly women and individuals with low education levels. These populations tend to have higher rates of non-response to treatment, suggesting the need for more intensive specialty mental health care.
Elderly women with depression are nearly twice as likely to develop heart failure over a 14-year period. Depression also increases the risk of physical illnesses like hypertension and diabetes that contribute to heart disease.

A University of Illinois study suggests that repetitive transcranial magnetic stimulation (rTMS) is a promising alternative to electroconvulsive therapy (ECT) for treating severe depression, with better tolerability and fewer side effects. rTMS showed significant improvement in depression scores, with a 55% reduction in the treatment g...
Children with chronic illnesses like cancer and diabetes may adapt by repressing emotions, but this defense mechanism can also hinder their ability to manage their illness.
Researchers at Georgetown University Medical Center are conducting a clinical trial to assess the effectiveness of venlafaxine HCI on post-traumatic stress disorder (PTSD).
