How self-reported hot flashes may relate to affect, cognitive performance and sleep.

Area of Science:

• Reproductive medicine
• Neuroscience
• Psychology

Background:

• Hot flashes are a common symptom during midlife, often associated with menopause.
• The relationship between hot flashes and neuropsychological symptoms like affect, cognition, and sleep remains controversial.
• Inconsistent findings in previous studies may stem from varied measurement methods.

Purpose of the Study:

• To investigate the association between self-reported and diary-documented hot flashes and neuropsychological symptoms in midlife women.
• To clarify the controversy surrounding the impact of hot flashes on affective symptoms, cognitive performance, and sleep quality.

Main Methods:

• Retrospective data analysis of 88 women experiencing hot flashes.
• Mixed linear regression modeling was used to assess associations.
• Hot flashes were measured using Women's Health Questionnaire (WHQ) items and daily diary documentation.
• Affective symptoms, cognitive performance, and sleep quality were also assessed.

Main Results:

• Diary-documented hot flashes, but not estimated ones, were significantly associated with increased anxiety and depression scores.
• Diary-documented hot flashes correlated with decreased performance on the Stroop Color-Word test.
• Significant associations were found between hot flashes and both subjective and objective sleep disturbances.
• Nighttime diary-documented hot flashes showed a consistent correlation with affect measures in multivariate analyses.

Conclusions:

• The choice of measurement tools for hot flashes, affect, cognition, and sleep significantly influences study outcomes.
• Discrepancies in measurement methods contribute to the ongoing debate about the link between hot flashes and neuropsychological symptoms.
• Standardizing measurement approaches is essential for establishing a consensus on the relationship between hot flashes and midlife women's well-being.
