A Cognitive Intervention to Manage 'Brain Fog' in Menopause Transition: Feasibility Study

February 3, 2026 updated by: University College, London

Cognitive complaints at menopause transition (MT), often described as 'brain fog'; can include difficulty recalling words and numbers, misplacing items, trouble concentrating and forgetfulness. Whilst these difficulties resolve for most people, several years of reduced cognitive functioning can be highly damaging and result in problems including leaving work, depression and relationship breakdown.

Study Aims: This project aims 1) to develop and finalise a cognitive intervention for the menopause, 2) To evaluate the feasibility, acceptability and preliminary effects of the intervention. 3) To evaluate the interventions preliminary effects on subjective and objective cognition

Relevance: Traditionally Menopause Hormone Therapy (MHT) is offered to women with cognitive complaints due to its beneficial effect. However, many women are unable to take it due to medical reasons or choose not to. If this intervention is concluded as feasible and acceptable it may then be appropriate to conduct a full RCT of this intervention. It could reduce excess disability, potentially enabling people to remain at work and function better in daily life. Costs to the NHS might be reduced through decreased service and medication use.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient Health Questionnaire-9 (PHQ-9)
Time Frame: Pre-intervention and within 6 weeks post intervention
The PHQ9 is a self-administered questionnaire measuring levels of depression over the past 2 weeks. The questionnaire uses a 4-point Likert rating scale, ranging from 0 (not at all) to 3 (nearly every day). The total score can range from 0 to 27, with high scores meaning high depression.
Pre-intervention and within 6 weeks post intervention
Generalised Anxiety Disorder (GAD-7)
Time Frame: Pre-intervention and within 6 weeks post intervention
The GAD 7 is a self-administered questionnaire measuring levels of anxiety over the past 2 weeks. The questionnaire uses a 4 Likert rating scale, ranging from 0 (not at all) to 3 (nearly every day). Total score can range from 0 to 21 and is categorised by 0-4 was no anxiety, 5-9 was mild anxiety, 10-14 was moderate anxiety, and 15 or above was severe anxiety.
Pre-intervention and within 6 weeks post intervention
Menopause-Specific Quality of Life (MENQoL)
Time Frame: Pre-intervention and within 6 weeks post intervention
The MENQoL measures the quality of life over 4 domains of menopausal symptoms: Vasomotor, Psychosocial, Physical and Sexual, asking if a symptom is present or not and if it is to score how bothersome it is on a 7-point Likert scale, ranging from 0 'not bothered at all' to 6 'extremely bothered.
Pre-intervention and within 6 weeks post intervention
Hot Flush Rating Scale (HFRS)
Time Frame: Pre-intervention and within 6 weeks post intervention
The HFRS is a self-report measure of the frequency and problem rating of hot flashes and night sweats (also known as vasomotor symptoms [VMS]) over the past week.
Pre-intervention and within 6 weeks post intervention
The Multifactoral Memory Questionnaire (MMQ)
Time Frame: Pre-intervention and within 6 weeks post intervention
The MMQ measures self-reported cognitive functions with three subscales: abilities, contentment, strategies. Items are rated on a 5-point scale (0-4), lower scores indicate worse perceived memory.
Pre-intervention and within 6 weeks post intervention
Menopause-specific Cognitive Scale (MENO-Cog)
Time Frame: Pre-intervention and within 6 weeks post intervention
The measure is in development with a PhD student in the same research team. It measures self-reported cognition functioning with a 5-point Likert scale; higher scores indicate worse perceived cognitive function.
Pre-intervention and within 6 weeks post intervention
Rey Auditory Verbal Learning Test (RAVLT)
Time Frame: Pre-intervention and within 6 weeks post intervention
The RAVLT is a neuropsychological test measuring verbal learning and (immediate and delayed) verbal memory.
Pre-intervention and within 6 weeks post intervention
Trail Making Test (TMT)
Time Frame: Pre-intervention and within 6 weeks post intervention
The TMT (Part A and B) is a neuropsychological test assessing executive function; shorter reaction times indicate better performance.
Pre-intervention and within 6 weeks post intervention
Digit Span subtest (WISC-V)
Time Frame: Pre-intervention and within 6 weeks post intervention
The Digit Span test (backward and forward) is a neuropsychological test assessing attention and working memory.
Pre-intervention and within 6 weeks post intervention
Controlled Word Association Test
Time Frame: Pre-intervention and within 6 weeks post intervention
The Controlled Word Association Test is a neuropsychological test assessing verbal fluency.
Pre-intervention and within 6 weeks post intervention

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Post intervention interviews
Time Frame: Pre-intervention and within 6 weeks post intervention
Around 15 participants will be invited to qualitative semi-structured audio-recorded interviews to explore their feedback of the intervention.
Pre-intervention and within 6 weeks post intervention
