The research also highlights the significant economic benefits, as the estimated annual cost of depression in Canada is $14 billion.
A two-year study of over 10,000 Medicare beneficiaries with diabetes found that depression was associated with a 36% increased risk of dying from any cause. Participants with both diabetes and depression were more likely to be female, have severe medical illness, and less likely to be African-American.
The adult brain's capacity for neurogenesis is closely tied to stress and depression, with research showing that chronic stress can inhibit new cell growth in the hippocampus. However, antidepressant treatment has been shown to stimulate neurogenesis, suggesting a potential therapeutic target for treating major depressive disorders.

A new study has found that women are 33 percent more likely to achieve full remission of their depression symptoms with the commonly used antidepressant citalopram compared to men. The study, which involved over 2,800 participants, controlled for various factors and suggests a biological basis for the difference in response.
Researchers at UT Southwestern Medical Center discovered that antidepressants need new nerve cells to reduce depression-like behavior in mice. Exercise also stimulates the generation of new nerve cells in the same area. The study suggests a possible mechanism for developing drugs to treat depression by stimulating growth of nerve cells.
A new study suggests that blocking the corticotrophin releasing factor-1 (CRF1) receptor and the vasopressin-1B (V1B) receptor may retain their efficacy in treating depression, even when neurogenesis is disrupted. The researchers found that restoration of the stress axis may be key to how these new antidepressant approaches work.
A study published by the American Psychological Association found that people taking antidepressants drive worse than those who aren't taking such drugs. Depressed drivers on meds performed significantly poorer in a driving simulation test.

This improvement was associated with a reduced risk of premature medication discontinuation and enhanced treatment adherence.
A study published in Biological Psychiatry found that deep brain stimulation (DBS) in the subcallosal cingulate region significantly improves symptoms of treatment-resistant depression. The procedure showed continued and sustained benefits over time, with no long-term side effects reported.
A new study has replicated the association between genetic variation in the FKBP5 gene and treatment response to antidepressants, suggesting a potential link to childhood maltreatment. The findings support earlier research implicating the same gene and provide encouragement for personalized medicine approaches to depression treatment.

Researchers found that white patients with two distinct gene variations were more likely to experience remission of symptoms associated with major depression. Pharmacogenetic testing could improve patient outcomes by matching patients with the right drug from the start.
Researchers at UNC have identified specific prescription drugs that increase the risk of falls for patients aged 65 and older who take four or more medications. These medications, including antidepressants and painkillers, work to depress the central nervous system, making patients less alert and slower to react.
Chronic stress can affect the adult brain's ability to generate new cells. Stress is associated with reduced neurogenesis, a process critical for developing novel antidepressant drugs.
Despite controversy over potential side effects on suicidal behaviour, antidepressant use in western countries correlates with declining suicide mortality. Experts like Professor Erkki Isometsä argue for a balanced view of clinical and epidemiological facts to inform treatment decisions.
A study found that selective serotonin reuptake inhibitors (SSRIs) are associated with increased gastrointestinal bleeding risk, especially when combined with other stomach-harming medications. Acid-suppressing agents may reduce this risk.
