Cognitive, Subjective and Demographic Data From the 'Addressing the Change in Memory' Study, 2021

The Addressing the ‘Change’ in Memory research project at Northumbria University assessed the cognitive performance and subjective state of 132 women experiencing self-reported ‘brain fog’ impacting on their work experience as a consequence of the menopause. This was followed by an investigation of whether daily use of extracts of rosemary Salvia rosmarinus over a three-month period would ameliorate any cognitive impairments or negative subjective states. The rosemary was consumed as either an infused water or via inhalation of the aroma of rosemary essential oil, with participants randomly allocated to one of the intervention conditions or a no intervention control group. Participants completed two practice assessments to counter any learning effects/familiarisation with the assessment platform, followed by a baseline assessment, three monthly intervention assessments and a final one-month post intervention assessment. All experimental data were collected online and provided eighteen measures of cognition (attention, working memory, executive function and long-term memory) and twenty measures of subjective state (mood, work experience, and health).
