About this study

Cognitive overload can be a common occurrence in an information saturated world (Eppler et al., 2008; Graf et al., 2021; Pass et al., 2004), and chronic cognitive overload is considered an initiating step in the emergence of various physical and emotional health concerns, likely due to high processing demands on the working memory neural system (Graf et al., 2021). Over time, psychological and physiological stress may arise, however current chemical interventions may be unsuitable for those experiencing mild-to-moderate levels of stress (Ghazizadeh et al., 2021). Indeed, long-term use of psychotropic medicines have previously been associated with a worsening of psychological symptoms (Bertuccioli et al., 2022). Therefore, identifying interventions for those experiencing mild-to-moderate stress will have strong public health implications for the prevention or reduction of symptoms. In addition, an opportunity for dietary supplementation as an over-the-counter option for those who do not wish to take chemical interventions is becoming a popular choice (Ghazizadeh et al., 2021; Bertuccioli et al. 2022).

The current study will employ a parallel, double-blind, randomised placebo-controlled trial, assessing the effect of a single dose intervention of lemon balm extract (or matched placebo) in young-to-middle-aged adults with moderate levels of perceived stress. Subjects will be pre-screened to determine eligibility using the perceived stress questionnaire, where scores between 14 to 26 are indicative of moderate stress, to provide a total of 130 participants. The study comprises a familiarisation visit followed by an acute test day at the Nutritional Psychology Unit based at the University of Reading. The familiarisation visit will allow participants to practice the cognitive battery, complete calmness and mood measures, and provide information on habitual diet (Epic-Norfolk FFQ) and general health and lifestyle patterns to confirm eligibility. On the acute test day, subjective calmness and mood ratings will be recorded at various timepoints throughout the day, beginning with an initial baseline measurement (0h), and then 1h, 3h and 5h after consuming an acute dose of lemon balm extract (300mg) or a matched placebo. At these same timepoints, a computer-based cognitive battery will be completed, consisting of several tasks assessing domains of executive function, attention and memory. On the acute test day participants will arrive fasted and will be provided with a standardised breakfast (two croissants and a glass of water) to be consumed prior to 0h baseline measures. A standardised lunch (cheese sandwich, packet of crisps, and water) will also be provided after the 3h timepoint.

  22. Modified Attention Network Task (with two blocks of Serial 3's)

    Time frame: Baseline

    A standardised measure to assess executive function and attention. In this task participants respond to the direction of a centrally presented arrow by pressing the corresponding left and right arrow keys. Across multiple trials, the target stimuli are either flanked by arrows pointing in the same direction (congruent) or opposite (incongruent). The number of flanking arrows also varies between trials (load). Two blocks are presented. In the second block, participants will be distracted by noise through headphones. In addition, during further subsections of the ANT an oral serial 3 (S3) subtractions task will also be performed to further assess attention and working memory function. In this S3 task participants subtract backwards starting with the number 50 until they can go no further. The S3 performance will be in place to add additional cognitive load and the dependent variable will be ANT performance (accuracy and reaction time) under varying conditions of congruency and load.

  26. Task Switching Test

    Time frame: Baseline

    A standardised cognitive task to assess executive function. In this task participants are presented with a computerised visual circle with 8 equally spaced radii that form 8 segments, 4 above and 4 below a bold line. A stimulus digit appears sequentially in each segment in a clockwise direction. If the digit was located above the bold line, participants then indicate whether the digit was odd or even using labelled arrow keys (left for odd, right for even). When the digit is below the bold line, participants again use the arrow keys to indicate whether the digit is higher or lower than 5 (left for higher, right for lower). The dependent variable will be TST performance (accuracy and reaction time) across all trials, and comparing switch trials (where the rule changes from the previous trial) and non-switch trials (where the rule stays the same as the previous trial).
