Religiosity and Risk of Parkinson's Disease in England and the USA

Parkinson's disease (PD) is associated with low religiosity cross-sectionally. Whether low religiosity might be associated with an increased risk for developing PD is unknown. This study investigated whether low religiosity in adulthood is associated with increased risk for developing PD. A population-based prospective cohort study was conducted. Participants from the English Longitudinal Study of Aging and the Midlife in the United States study who were free from PD at baseline (2004-2011) and completed questionnaires on self-reported religiosity, were included in a pooled analysis. Incident PD was based on self-report. Multivariable logistic regression was used to estimate odds ratios (OR) for developing PD according to baseline religiosity, with adjustment for sociodemographic characteristics, health and lifestyle factors and engagement in religious practices. Among 9,796 participants in the pooled dataset, 74 (0.8%) cases of incident PD were identified during a median follow-up of 8.1 years. In the fully adjusted model, compared with participants who considered religion very important in their lives at baseline, it was found that participants who considered religion "not at all important" in their lives had a tenfold risk of developing PD during follow-up (OR, 9.99; 95% CI 3.28-30.36). Moreover, there was a dose-response relationship between decreasing religiosity and increasing PD risk (P < 0.001 for trend). These associations were similar when adjusting for religious upbringing and when cases occurring within the first two years of follow-up were excluded from the analysis. The association was somewhat attenuated when religious practices were removed from the model as covariates, though it remained statistically significant (OR for "not at all important" vs. "very important", 2.26; 95% CI 1.03-4.95) (P < 0.029 for trend). This longitudinal study provides evidence for the first time that low religiosity in adulthood may be a strong risk factor for developing PD.

Regional Brain Volume Changes in Catholic Nuns: A Cross-Sectional Study Using Deep Learning-Based Brain MRI Segmentation

OBJECTIVE

Religious behaviors are considered as complex brain-based phenomena that may be associated with structural brain change. To identify the pattern of regional brain volume change in nuns, we investigated structural alterations in the brains of nuns using a fast processing automated segmentation method based on deep learning algorithms.

METHODS

We retrospectively reviewed the medical records of the catholic sisters between the ages of 31 and 80 who are members of the charity of St. Vincent de Paul of Korea. A total of 193 asymptomatic subjects (86 nuns and 107 control subjects) received comprehensive health screening and underwent brain MRI scans. We compared cortical and sub-cortical volume between groups across multiple locations using our in-house U-Net++ deep learning-based automatic segmentation tool.

RESULTS

Compared to the control group, the nun group displayed increased gray matter volume in the right lingual cortex, left isthmus-cingulate, posterior-cingulate, rostral-middle-frontal, superior-frontal, supramarginal, temporal-pole cortices, and bilateral pars-triangularis cortices after correction for multiple comparisons. On the other hand, the nun group showed reduced gray matter volume in the temporal and parietal regions relative to healthy controls.

CONCLUSION

Our study suggests that spiritual practice may affect brain structure, especially in several frontal regions involved in a higher level of insight function.

Spirituality, religiousness, and mental health: A review of the current scientific evidence

Research in the field of “Spirituality and Health” has been growing, with spirituality/religiousness (S/R) being consistently related to both physical and mental health. The objective of this article is to provide an updated review of the current scientific evidence on the relationship between S/R and mental health, highlighting the most important studies. As a secondary objective, the mechanisms that explain this relationship and the interventions that utilize this information in treating mental disorders will be discussed. The findings reveal a large body of evidence across numerous psychiatric disorders. Although solid evidence is now available for depression, suicidality, and substance use, other diagnosis, such as post-traumatic stress disorder, psychosis, and anxiety, have also shown promising results. The effects of S/R on mental health are likely bidirectional, and the manner in which religious beliefs are used to cope with distress (i.e. negative and positive), may affect mental health outcomes. Despite these findings, the mechanisms that explain these associations and the role of S/R interventions need further study. Concerning clinical practice, mental health providers should ask patients about S/R that are important in their lives to provide holistic and patient-centered care.

The mechanism of electroacupuncture for depression on basic research: a systematic review

BACKGROUND

Electroacupuncture (EA) is generally accepted as a safe and harmless treatment option for alleviating depression. However, there are several challenges related to the use of EA. Although EA has been shown to be effective in treating depression, the molecular mechanism is unclear.

OBJECTIVE

To reveal the therapeutic effect of EA and its possible mechanism in the treatment of depression.

SEARCH STRATEGY

We performed a systematic search according to PRISMA guidelines. We electronically searched PubMed, Web of Science (WOS), the China National Knowledge Infrastructure (CNKI), Wanfang Data Information Site and the VIP information database for animal studies in English published from the inception of these databases to December 31, 2019.

INCLUSION CRITERIA

Electronic searches of PubMed, WOS, the CNKI, Wanfang and the VIP database were conducted using the following search terms: (depression OR depressive disorder OR antidepressive), (rat OR mouse) AND (acupuncture OR EA).

DATA EXTRACTION AND ANALYSIS

The data were extracted primarily by one author, and a follow-up review was conducted by the other authors.

RESULTS

Twenty-eight articles met the inclusion criteria. The most commonly used method for inducing depression in animal models was 21 days of chronic unpredictable mild stress. For the depression model, the most commonly selected EA frequency was 2 Hz. Among the 28 selected studies, 11 studies observed depression-related behaviors and used them as indicators of EA efficacy. The other 17 studies focused on mechanisms and assessed the indexes that exhibited abnormalities that were known to result from depression and then returned to a normal range after EA treatment. Treatment of depression by EA involves multiple therapeutic mechanisms, including inhibition of HPA axis hyperactivity and inflammation, regulation of neuropeptides and neurotransmitters, modulation of the expression of particular genes, restoration of hippocampal synaptic plasticity, increased expression of BDNF, and regulation of several signaling pathways.

CONCLUSIONS

This review reveals that the mechanisms underlying the effect of acupuncture involve multiple pathways and targets, suggesting that acupuncture is a wholistic treatment for people rather than for diseases. Our findings also explain why acupuncture can treat various disorders in addition to depression.

Spiritual Fitness: A New Dimension in Alzheimer's Disease Prevention

BACKGROUND

Religious and spiritual interventions may have an effect on Alzheimer's disease prevention. Kirtan Kriya meditation has been shown to mitigate the deleterious effects of chronic stress on cognition, reverse memory loss, and create psychological and spiritual wellbeing, which may reduce multiple drivers of Alzheimer's disease risk.

OBJECTIVE

To detail a new concept in medicine called Spiritual Fitness, a merging of stress reduction, basic wellbeing, and psycho/spiritual wellbeing to prevent Alzheimer's disease.

METHODS

The literature on the topics mentioned above is described, including an in-depth discussion on why and how each are critical to advancing the future of Alzheimer's disease prevention. The many negative effects of chronic stress, and the benefits of Kirtan Kriya, are reviewed. The four pillars of basic wellbeing, six practical aspects of psychological wellbeing, and the four new non-sectarian features of spiritual fitness are then disclosed. Moreover, instructions on practicing Kirtan Kriya are offered in the Supplementary Material.

CONCLUSION

Religious and spiritual practices, including Kirtan Kriya, are crucial components in the development of enhanced cognition and well-being, which may help prevent and, in some cases, reverse cognitive decline. The key point of this review is that making a commitment to live a brain longevity lifestyle including spiritual fitness is a critically important way for aging Alzheimer's disease free. We hope that this article will inspire scientists, clinicians, and patients to embrace this new concept of spiritual fitness and make it a part of every multidomain program for the prevention of cognitive disability.

Religious Coping, Hopelessness, and Suicide Ideation in Subjects with First-Episode Major Depression: An Exploratory Study in the Real World Clinical Practice

BACKGROUND

This study aimed to evaluate the potential relationships between religious coping, hopelessness, and suicide ideation in adult outpatients with the first episode of major depressive disorder (MDD).

METHODS

Ninety-four adult outpatients with MDD were assessed through the Hamilton Depression Rating Scale (HAM-D), the Beck Hopelessness Scale (BHS), and the Scale of Suicide Ideation (SSI). Religious coping was assessed with the Italian version of the Brief RCOPE scale, consisting of seven positive coping items (PosCop) and seven negative coping items (NegCop).

RESULTS

The results showed that the Brief RCOPE PosCop scale exhibited a strong inverse correlation with HAM-D, BHS, and SSI, whereas HAM-D and BHS were positively correlated with SSI. Brief RCOPE NegCop scores were positively correlated only with SSI. Regression analysis with SSI as the dependent variable showed that higher Brief RCOPE PosCop scores were associated with lower suicide ideation, whereas higher HAM-D and BHS scores were associated with higher suicide ideation.

CONCLUSION

Positive religious coping may be a protective factor against the development of suicide ideation, perhaps counteracting the severity of depressive symptoms and hopelessness. The evaluation of religious coping should be performed in all subjects with MDD in everyday clinical practice. However, this study was preliminary, and limitations must be considered.

Predicting Depression Symptoms in Families at Risk for Depression: Interrelations of Posterior EEG Alpha and Religion/Spirituality

BACKGROUND

Posterior EEG alpha has been identified as a putative biomarker of clinical outcomes in major depression (MDD). Separately, personal importance of religion and spirituality (R/S) has been shown to provide protective benefits for individuals at high familial risk for MDD. This study directly explored the joint value of posterior alpha and R/S on predicting clinical health outcomes of depression.

METHODS

Using a mixed-effects model approach, we obtained virtual estimates of R/S at age 21 using longitudinal data collected at 5 timepoints spanning 25 years. Current source density and frequency principal component analysis was used to quantify posterior alpha in 72-channel resting EEG (eyes open/closed). Depression severity was measured between 5 and 10 years after EEG collection using PHQ-9 and IDAS-GD scales.

RESULTS

Greater R/S (p = .008, η²_p = 0.076) and higher alpha (p = .02, η²_p = 0.056) were separately associated with fewer symptoms across scales. However, an interaction between alpha and R/S (p = .02, η²_p = 0.062) was observed, where greater R/S predicted fewer symptoms with low alpha but high alpha predicted fewer symptoms with lower R/S.

LIMITATIONS

Small-to-medium effect sizes and homogeneity of sample demographics caution overall interpretation and generalizability.

CONCLUSIONS

Findings revealed a complementary role of R/S and alpha in that either variable exerted protective effects only if the other was present at low levels. These findings confirm the relevance of R/S importance and alpha oscillations as predictors of depression symptom severity. More research is needed on the neurobiological mechanism underlying the protective effects of R/S importance for MDD.
