RESUMO

INTRODUCTION: Family caregivers of patients with dementia suffer a high burden of depression and reduced positive emotions. Mentalizing imagery therapy (MIT) provides mindfulness and guided imagery skills training to improve balanced mentalizing and emotion regulation. OBJECTIVE: Our aims were to test the hypotheses that MIT for family caregivers would reduce depression symptoms and improve positive psychological traits more than a support group (SG), and would increase dorsolateral prefrontal cortex (DLPFC) connectivity and reduce subgenual anterior cingulate cortex (sgACC) connectivity. METHODS: Forty-six caregivers participated in a randomized controlled trial comparing a 4-week MIT group (n = 24) versus an SG (n = 22). Resting state neuroimaging was obtained at baseline and post-group in 28 caregivers, and questionnaires completed by all participants. The primary outcome was change in depression; secondary measures included anxiety, mindfulness, self-compassion, and well-being. Brain networks with participation of DLPFC and sgACC were identified. Connectivity strengths of DLPFC and sgACC with respective networks were determined with dual regression. DLPFC connectivity was correlated with mindfulness and depression outcomes. RESULTS: MIT significantly outperformed SG in improving depression, anxiety, mindfulness, self-compassion, and well-being, with moderate to large effect sizes. Relative to SG, participants in MIT showed significant increases in DLPFC connectivity - exactly replicating pilot study results - but no change in sgACC. DLPFC connectivity change correlated positively with mindfulness and negatively with depression change. CONCLUSIONS: In this trial, MIT was superior to SG for reducing depression and anxiety symptoms and improving positive psychological traits. Neuroimaging results suggested that strengthening DLPFC connectivity with an emotion regulation network might be mechanistically related to MIT effects.

RESUMO

PURPOSE OF REVIEW: With the current demographic shifts, the USA will soon become a "majority minority" country. While the population of the USA over the age of 65 years is projected to increase from 13.5% to 20% in 2030, racial and ethnic minority elderly, who are now 21% of the population, will increase to 44% by 2060. As the population of racial and ethnic minority elderly continues to grow, there is a demographic and public health imperative to understand how to better care for this population. RECENT FINDINGS: This review evaluates the impact of race, ethnicity, and culture on the aging process, psychopathology, psychiatric care, psychiatric education, and clinical research. Relevant advances in recent literature are reviewed, and gaps in cultural competency education and training, and clinical research are identified. Clinical recommendations and future directions are highlighted, as an effort to improve care for this underserved population at risk. By striving to better care for racial and ethnic minority elders, one of the most marginalized populations, health care is improved for all.

RESUMO

BACKGROUND: The optimal dose of S-adenosyl methionine (SAMe) for major depressive disorder (MDD) remains unclear. The objective of this analysis was to address whether a dose increase provided further improvement in cases of insufficient response using data from an existing randomized clinical trial. METHODS: Sixty-five patients with MDD who failed to respond to SAMe 1,600 mg/day, escitalopram 10 mg/day, or placebo for 6 weeks were treated with doubled doses of the allocated treatments for the following 6 weeks. Changes in 17-item Hamilton Depression Rating Scale, Inventory of Depressive Symptomatology-Self Rated, and Systematic Assessment for Treatment Emergent Events-Specific Inquiry were compared between the lower and higher dose treatments in each treatment group and among the higher dose treatments of SAMe, escitalopram, and placebo. RESULTS: Various depression severity scores decreased significantly for all three treatment arms during the higher dose treatment. No within-group and between-group differences were found in any of the efficacy measures when comparing the doses and treatments. There was a significant difference in reported abdominal discomfort among patients receiving the higher dose of SAMe (31.3%), compared to escitalopram (8.7%) and placebo (3.8%) (χ2=7.32, p = 0.026). LIMITATIONS: The sample size was relatively small. The study duration for dose increase was relatively short. CONCLUSIONS: Patients with MDD failing to respond to 1,600 mg/day of SAMe may improve after increasing the dose to 3,200 mg/day, but we cannot rule out the contribution of a placebo effect and time-related improvement. The risk of abdominal discomfort may be increased with higher doses of SAMe.
