The study found that depressed individuals have a greater proportion of Gs alpha protein confined to lipid rafts, which can be used to predict the efficacy of antidepressant therapy.
A new study found that depressed heart attack patients have a higher risk for sudden death in the months following a heart attack, and this risk continues for many years. The study of over 750 patients showed that even minor depression increases mortality risk.
A study found that adolescents with ineffective depression medication saw improved symptoms when switching to a different antidepressant and adding cognitive behavioral therapy. The combination of treatments resulted in a higher rate of clinical response compared to changing medications alone.
A recent study published in JAMA found that teenagers with difficult-to-treat depression who switched to another antidepressant medication and added psychotherapy showed significant improvement. The results suggest that a combination approach may be more effective than traditional treatment strategies for adolescents with treatment-res...
A study found that nearly 55% of teenagers with treatment-resistant depression showed improvement when switched to a different medication combined with cognitive behavioral therapy. The results suggest that clinicians should not hesitate to switch treatments, especially if an adolescent hasn't responded to initial treatment.
A new study published in PLoS Medicine suggests that antidepressants only provide clinically significant benefits for a small group of severely depressed patients. However, even among these patients, the improvement is not very great, and depressed people can still improve without chemical treatments.
A new study finds that ketamine's antidepressant effects are mediated by its ability to increase AMPA receptor stimulation, suggesting drugs enhancing this function may have rapid antidepressant properties. Researchers now aim to develop AMPA-boosting drugs without ketamine's side effects.
A meta-analysis of 34 clinical trials found venlafaxine (SNRI) outperformed SSRIs in treating depression, resulting in a 5.9% increased remission rate. This translates to the need for doctors to treat 17 patients with venlafaxine to achieve one patient's benefit.
Researchers found that patients with depression may not experience improvements in hopefulness until several weeks or months after their depressive symptoms lift. This delay can lead to reduced adherence to treatment, increasing the risk of suicidal thoughts and behaviors.
A new study by Yale School of Medicine researchers found that older women are more prone to depression and less likely to die from it compared to older men. The study, which evaluated 754 individuals aged 70+, found that women were more likely to experience symptoms of depression and remain depressed over time.
Research reveals that doctors are reluctant to prescribe sleep aids to patients with depression, anxiety, or mood disorders, except for psychiatrists. However, new guidelines are needed to address this knowledge gap and ensure patients receive appropriate treatment for their insomnia.
Researchers identified genetic variants that affect the efficacy of antidepressants, such as citalopram and venlafaxine. These variants influence the access of drugs to the brain by impacting protective transporter proteins like P-gp.
