Late-life depression affects 2-6% of seniors aged 60 years and above. Patients are increasingly embracing non-pharmacological therapies, many of which have not been scientifically evaluated. This study aimed to evaluate a category of meditation, automatic self-transcending meditation (ASTM), in alleviating symptoms of depression when augmenting treatment as usual (NCT02149810). The preliminary results of an ongoing single-blind randomised controlled trial comparing a training programme involving ASTM with a wait-list control indicate that a 12-week ASTM programme may lead to significantly greater reductions in depression and anxiety severity. As such, ASTM may be an effective adjunctive therapy in the treatment of late-life depression.

BackgroundStructural brain abnormalities are associated with late-life major depression, with numerous studies reporting increased white matter hyperintensities (WMH) and reduced cortical/subcortical grey matter volumes. There is strong evidence linking vascular disease to WMH, but limited evidence on its association with subcortical volumes.AimsTo investigate the relationship of orthostatic blood pressure changes to WMH and subcortical grey matter volumes in late-life depression.MethodThirty-eight people with depression and a similarly aged comparison group (n = 30) underwent fluid attenuated inversion recovery (FLAIR) and T1-weighted magnetic resonance imaging as well as systematic orthostatic blood pressure assessments. Volumetric estimates of WMH and subcortical grey matter were obtained for each participant and the relationship to blood pressure drop on active stand was examined.ResultsAn association between orthostatic systolic blood pressure drop and WMH volumes in temporal and parietal regions was found in the depression group (age-corrected partial correlation r’ = 0.31–0.35, PConclusionsWe found evidence for an association between the degree of orthostatic systolic blood pressure drop and WMH volume in the depression group. Since blood pressure drops lead to WMH in animals our findings suggest systolic blood pressure drops may be a factor contributing to these lesions in late-life depression.

Aims and MethodA cross-sectional survey of patient drug prescriptions on two elderly psychiatric wards was carried out to estimate the potential of drug–drug interactions. Two standardised databases, British National Formulary (BNF; British Medical Association & Royal Pharmaceutical Society of Great Britain, 2007) and Upto Date (www.uptodate.com/), were employed.ResultsA majority (96%) of drug prescriptions in our study could potentially cause drug–drug interactions. Most patients were on multiple drugs (on average eight drugs per patient). There was poor concordance between the two databases: BNF picked up fewer cases of potential drug–drug interactions than Upto Date (43 v. 152 instances) and they also estimated the potential for hazardousness differently.Clinical ImplicationsPolypharmacy is common in elderly psychiatric patients and this increases the possibility of a drug–drug interaction. Estimating the risk of interactions depends on a sound knowledge in therapeutics and/or referring to a standardised source of information. the results of this study question the concordance of two well-referenced databases.
