The study's findings suggest that cannabidiol rapidly triggers neuroplastic mechanisms to repair damaged neuronal circuitry, providing new hope for treating broad-spectrum depression.
A new study found that ketamine's antidepressant effect requires opioid system activation in humans, raising concerns about the risk of dependence. The study used naltrexone, an opioid blocker, to block ketamine's effects and found that it reduced antidepressant symptoms but not dissociative effects.
Stanford researchers found that ketamine works as an antidepressant by activating the brain's opioid system. The study overturns previous beliefs about the drug's mechanism and presents new treatment opportunities for depression, pain, and opioid addiction.
A study found that nearly 20% of children use prescription medications, with 7.5% using multiple medications simultaneously. Adolescent girls are most vulnerable to harmful drug-drug interactions due to higher concurrent use of antidepressants and other psychotropic medications.

The researchers discovered increased male aggression towards females receiving the medication, leading to a higher risk of mate failure and population decline.
Next-generation metabolomics may facilitate the discovery of new antidepressants by providing broader coverage and higher resolution than traditional methods. The technique has demonstrated great potential in accelerating pharmaceutical R&D, particularly for natural products like albiflorin, a promising multi-target drug candidate.
Individuals with MDD have lower LAC levels than healthy controls, increasing with disease severity and age of onset. Patients with low LAC levels often do not respond to standard antidepressant medications, suggesting LAC may aid in diagnosing severe, trauma-associated depression.
A new review of published observational studies reveals that depression and the use of antidepressants are both associated with an increased risk of VTE. The study's findings suggest that prescribers and healthcare professionals should evaluate patients to determine their excess risk of VTE during management.

A new study finds that antidepressant use in people with chronic obstructive pulmonary disease (COPD) is associated with a 20% increase in likelihood of death and a 15% increase in hospitalization due to respiratory-related symptoms. The study suggests strong association, but not cause and effect.
Researchers found ketamine's rapid antidepressant effect is linked to the fast release of G proteins from membrane patches. This allows for better communication among brain cells, alleviating depressive symptoms. The long-lasting effects may be due to slow G protein re-entry into lipid rafts.
Researchers used EEG to measure brain response to rewards in patients with depression and anxiety. They found that increased reward positivity was associated with symptom improvement, and those with blunted reward positivity responded better to antidepressant medication.
A study by University of California - Davis researchers finds that psychedelic drugs increase dendritic branches and spines, promoting neural plasticity. This structural change mirrors the effects of ketamine, a treatment-resistant antidepressant.
A study by Hiroshima University found a link between the protein RGS8 and depression behaviors in mice. RGS8 may be a promising candidate for developing new antidepressant drugs.
A new study analyzing data from Danish women found that taking antidepressants did not change significantly before or after an abortion, and actually decreased over time. The research supports recent reports concluding that abortion does not cause depression, anxiety, or PTSD.
Researchers at King's College London found that patients prescribed antidepressants were 21% more likely to experience weight gain than those not taking the drugs. The risk of weight gain remained elevated for up to six years, with peak risk periods after two to three years of continued use.
A UK-based research team found that prolonged antidepressant use is associated with a sustained increase in weight gain over at least five years. The study analyzed data from over 300,000 adults and showed that patients prescribed any of the 12 most commonly used antidepressants were more likely to experience weight gain.
Depression in male partners is associated with reduced conception and live birth rates among infertile couples. Women taking non-SSRI antidepressants also experience higher early pregnancy loss rates.
