What is the purpose of this trial?

This trial aims to understand how stress affects memory and navigation in healthy aging. Researchers will divide participants into two groups: one will navigate tasks with anticipatory psychological stress (also known as stress manipulation or psychological stress induction), and the other without. The study will explore how stress might cause people to rely on habits rather than planning efficient routes. It seeks adults aged 65-80 who are fluent in English and can attend sessions at Georgia Tech. Those with conditions like epilepsy, dementia, or untreated diabetes are not eligible.

As an unphased study, this trial offers participants the opportunity to contribute to groundbreaking research on aging and stress.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it excludes those taking medication affecting the cardiovascular system, like beta-blockers. It's best to discuss your specific medications with the trial coordinators.

What prior data suggests that this protocol is safe?

Research has shown that stress affects the body in various ways. For instance, stress can accelerate cellular aging by shortening telomeres, which act as protective caps on DNA ends. It can also increase inflammation, linked to numerous health issues.

In this trial, the stress is anticipatory, involving the expectation of a stressful event rather than direct experience. Studies have examined how this type of stress affects individuals, such as increasing reliance on habits over careful planning in certain situations.

Overall, psychological stress is considered safe in controlled research settings like this one. Researchers closely monitor participants to manage any discomfort. While stress can have significant effects over time, the type used in this study is not expected to cause harm in the short term. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores how anticipatory psychological stress affects navigation in aging, which is a relatively uncharted area. Unlike traditional treatment approaches that focus on pharmacological interventions or cognitive training to support navigation skills in older adults, this trial investigates the impact of psychological stress, specifically the anticipatory threat of shock, on cognitive tasks. By understanding this relationship, researchers hope to uncover new insights into how stress affects cognitive processes, potentially leading to innovative strategies to enhance navigation and cognitive resilience in aging populations.

What evidence suggests that anticipatory psychological stress is effective for studying navigation in aging?

This trial will compare the effects of psychological stress on navigation skills in aging. Research has shown that stress significantly impacts aging, particularly memory and navigation skills. For older adults, sudden stress might hinder tasks requiring quick thinking or strategy changes. Studies have found that stress can lead older adults to rely on less effective habits rather than using memory to plan better routes. Consequently, stress might impair the ability to think ahead and adapt to new situations. These findings highlight stress's impact on the brain's ability to process and respond to information in older adults. Participants in this trial will perform tasks either under manipulated psychological stress or without stress manipulation, allowing for a direct comparison of these effects. ^{1 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• Anticipatory psychological stress

Trial Overview

The study examines how stress affects memory and navigation in aging adults by assigning them to a stressed group or control group during a novel navigation task. Using neuroimaging and behavioral measures under stress-induced conditions versus normal circumstances will reveal the impact on spatial memory and route planning abilities.

How Is the Trial Designed?

Group I: Stress group Experimental Treatment 1 Intervention

Participants in this group will perform the psychology tasks (virtual navigation) under manipulated psychological stress (anticipatory threat of shock)

Group II: No-stress control group Active Control 1 Intervention

Participants in this group will perform the psychology tasks (virtual navigation) without any manipulation of psychological stress

About 19% of older adults experienced at least one medically serious adverse medical event (AME), with a higher risk among those in poorer health and with more comorbidities, indicating a need for targeted monitoring and prevention strategies.

Experiencing an AME significantly increased Medicare expenditures during and after the event, and was associated with a lower survival rate, as only 55% of those with an AME survived to the end of the study compared to nearly 80% of those without an AME.

Psychological stress significantly impacts the elderly, leading to anxiety, insecurity, and depression, which can hinder their overall well-being.

The review highlights that the cellular and molecular mechanisms of psychological stress are not well understood, yet they play a crucial role in compromising healthy aging.

In a study of 838 health professionals in Colombia from 2017 to 2021, 33.8% reported experiencing adverse events, with 21.91% showing medium-high emotional overload and 3.53% experiencing extreme acute stress.

The risk of developing acute stress after an adverse event was found to be significant, with a prevalence ratio of 1.30, indicating that health institutions need to address this issue to improve care capacity and support their staff.

A study involving 94 elderly participants showed that an educational intervention based on the PRECEDE model significantly reduced stress levels, as measured by the DASS 21 questionnaire, after eight weeks of training.

The intervention improved knowledge, attitudes, and practical skills like deep breathing and relaxation techniques, indicating that structured educational programs can effectively help manage stress in older adults.

The safety of psychological interventions is critical, as adverse events (AEs) can occur and must be carefully evaluated to ensure that these interventions do not cause harm before being deemed beneficial.

There is a pressing need for standardized protocols for assessing and reporting AEs in psychological interventions to improve transparency, consistency, and ultimately enhance clinical practice.

In a study of 212 older adults aged 58 to 103, optimism was found to significantly mediate the relationship between perceived stress and psychological health, indicating that a positive outlook can help buffer the effects of stress.

Perceived control over internal states also played a crucial role, mediating the relationships among stress, optimism, and psychological health, suggesting that enhancing these factors could improve psychological adjustment in older adults facing stress.

In a survey of 874 older adults, 20.3% reported experiencing adverse drug events (ADEs), with stronger concerns about medications and more reported symptoms significantly linked to these events.

Interestingly, the use of inappropriate medications was not significantly associated with self-reported ADEs, suggesting that patients' beliefs and concerns about their medications may play a more critical role in their experiences of side effects.

A study involving 240 adults aged 25-65 found that anticipating stress in the morning negatively impacts spatial working memory performance later that day, regardless of actual stress experienced throughout the day.

Psychological stress has a significant and lasting impact on the aging process, potentially accelerating epigenetic aging, which is measured by DNA methylation and serves as a biomarker for aging.

While some evidence suggests that epigenetic aging may be modifiable through interventions, further research is needed to explore the preventability or reversibility of these changes and their clinical implications.
