Older adults experience symptoms of depression, leading to suffering and increased morbidity and mortality. Although we have effective depression therapies, physical distancing and other public health measures have severely limited access to in-person interventions.

To describe the efficacy of virtual interventions for reducing symptoms of depression in community-dwelling older adults.

Systematic review.

We searched MEDLINE, EMBASE, Cochrane Libraries, PsycINFO, and gray literature from inception to July 5, 2021.

We included randomized trials (RCTs) comparing the efficacy of virtual interventions to any other virtual intervention or usual care in community-dwelling adults ≥60 years old experiencing symptoms of depression or depression as an outcome.

The primary outcome was change in symptoms of depression measured by any depression scale.

We screened 12,290 abstracts and 830 full text papers. We included 15 RCTs (3100 participants). Five RCTs examined persons with depression symptoms at baseline and ten examined depression as an outcome only. Included studies demonstrated feasibility of interventions such as internet or telephone cognitive behavioral therapy with some papers showing statistically significant improvement in depressive symptoms.

There is a paucity of studies examining virtual interventions in older adults with depression. Given difficulty in accessing in-person therapies in a pandemic and poor access for people living in rural and remote regions, there is an urgent need to explore efficacy, effectiveness, and implementation of virtual therapies.

Pilot randomized double-blind-controlled trial of repetitive paired associative stimulation (rPAS), a paradigm that combines transcranial magnetic stimulation (TMS) of the dorsolateral prefrontal cortex (DLPFC) with peripheral median nerve stimulation.

To study the impact of rPAS on DLPFC plasticity and working memory performance in Alzheimer’s disease (AD).

Thirty-two patients with AD (females = 16), mean (SD) age = 76.4 (6.3) years were randomized 1:1 to receive a 2-week (5 days/week) course of active or control rPAS. DLPFC plasticity was assessed using single session PAS combined with electroencephalography (EEG) at baseline and on days 1, 7, and 14 post-rPAS. Working memory and theta–gamma coupling were assessed at the same time points using the N-back task and EEG.

There were no significant differences between the active and control rPAS groups on DLPFC plasticity or working memory performance after the rPAS intervention. There were significant main effects of time on DLPFC plasticity, working memory, and theta–gamma coupling, only for the active rPAS group. Further, on post hoc within-group analyses done to generate hypotheses for future research, as compared to baseline, only the rPAS group improved on post-rPAS day 1 on all three indices. Finally, there was a positive correlation between working memory performance and theta–gamma coupling.

This study did not show a beneficial effect of rPAS for DLPFC plasticity or working memory in AD. However, post hoc analyses showed promising results favoring rPAS and supporting further research on this topic. (Clinicaltrials.gov-NCT01847586)

Ageism is defined as stereotypes, prejudice, and discrimination towards people because of their age. Although ageism can be directed towards people of any age group, most research has focused on ageism towards older people. Ageism towards older people is known to have a significant impact on their health and wellbeing and to even result in higher healthcare costs. The present study evaluated the use of virtual embodiment (VE) to reduce self- and other-directed ageism.

We randomized 80 individuals between the ages of 18 and 35 years to one of two conditions: VE as an older or a younger avatar.

No differences were found on explicit measures of ageism. Once multiple comparisons were accounted for, a nonsignificant reduction in implicit age bias following exposure to the older avatar (Cohen’s d = .75, p = .02) also was found.

Past research has established the effectiveness of VE in relation to implicit measures. However, once both explicit and implicit measures are included and multiple comparisons are accounted for, neither explicit nor implicit measures of ageism show a significant effect. Given the multidimensional nature of ageism, further research is needed to establish the effectiveness of VE once multiple measures of ageism are considered.
