: Major Depressive Disorder (MDD) is a prevalent and debilitating mental disorder that has been linked to hyperhomocysteinemia and folate deficiency. These conditions are influenced by the methylenetetrahydrofolate reductase () gene, which plays a crucial role in converting homocysteine to methionine and is essential for folate metabolism and neurotransmitter synthesis, including serotonin. : This study explored the association between and polymorphisms among Saudi MDD patients attending the Erada Complex for Mental Health and Erada Services outpatient clinic in Jeddah, Saudi Arabia.

Objective: To determine the relative effectiveness of combination therapy of antidepressants with low-dose methylfolate versus antidepressant monotherapy in patients with depressive disorder.

Methods: In an open-label clinical trial, forty-four patients with depressive disorder (6A70, 6A71, and 6A72 according to ICD-11) received an evidence-based antidepressant therapy (either escitalopram 10-20 mg, sertraline 50-100 mg, fluoxetine 20-40 mg, duloxetine 30-60 mg, mirtazapine 15-30 mg, venlafaxine 75-150 mg, trazodone 50-100 mg, amitriptyline 25-75 mg, or clomipramine 25-75 mg orally daily for 4 weeks).

Background: Few studies have explored the effects of arsenic exposure on depressive symptoms and the underlying mechanisms of its influence on this relationship. This study aimed to assess the impact of urinary arsenic on depressive symptoms and the mediating and moderating roles of folate and dietary inflammation index (DII).

Methods: Cross-sectional data from 9775 participants (≥20 years) in the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2020 were used for analysis.

Association of Vitamin B12 and Polymorphism of with Early-Onset Post-Stroke Depression.

Neuropsychiatr Dis Treat

November 2024

Department of Neurology, Xiangya Hospital, Central South University, Changsha, Hunan, 410005, People's Republic of China.

Article Synopsis
  • - The study investigates the connection between vitamin B12, folate, their transporter genes, and post-stroke depression (PSD) in 173 ischemic stroke patients, finding a significant link between low vitamin B12 levels and a high incidence of PSD (48.6%).
  • - Results show that individuals with the GG genotype of the rs1801198 SNP have an increased risk of developing PSD, with odds ratios indicating a strong association after adjusting for other factors.
  • - The findings suggest that vitamin B12 levels and the rs1801198 SNP may play a role in the onset of early PSD, offering new perspectives for potential treatments.
