Forgetfulness and Word-Finding Difficulties Are Directly Related to Menopause
Yes, forgetfulness and word-finding difficulties are recognized symptoms associated with menopause, though the evidence linking them directly to hormonal changes is less consistent than for vasomotor symptoms like hot flashes. 1
What the Evidence Shows About Cognitive Changes in Menopause
Recognized Cognitive Symptoms
Cognitive dysfunction, often described as "brain fog," is commonly reported during the menopausal transition and includes: 1
- Forgetfulness and memory difficulties - particularly affecting verbal learning and memory 2
- Word-finding difficulties - specifically mentioned as a patient-reported symptom 2
- Difficulty with concentration 2
- Distractibility 2
Important Distinction: Correlation vs. Direct Causation
The direct link between cognitive changes and menopause is less consistently established than other classic menopausal symptoms (like hot flashes, night sweats, vaginal dryness, and sleep disturbances). 2, 1 This means while many women experience these cognitive symptoms during menopause, they may not be solely or directly caused by hormonal changes. 2
Contributing Factors Beyond Hormones
Sleep Disruption as a Major Culprit
Night sweats and hot flashes disrupt sleep patterns, which independently causes cognitive impairment, fatigue, and memory problems. 1, 3 This creates a cascade where hormonal changes cause vasomotor symptoms, which disrupt sleep, which then impairs cognition. 4
Mood and Psychological Factors
- Depression and anxiety are consistently linked to the menopausal transition and independently affect cognitive function 2, 1
- Mood disturbances can manifest as perceived cognitive difficulties even when objective testing shows minimal impairment 2
Other Confounding Variables
Cognitive changes may be related to aging itself, psychological disorders, or treatment effects (in cancer patients) rather than menopause specifically. 2 The challenge is that these factors often overlap during midlife, making it difficult to isolate menopause as the sole cause. 5
The Hormonal Mechanism (When Present)
When cognitive changes are hormonally mediated, the mechanism involves: 2
- Estrogen's neuroprotective effects - estrogen regulates oxidative metabolism in brain mitochondria and influences neuroplasticity 2
- Reduced estradiol decreases BDNF (brain-derived neurotrophic factor) expression, which affects memory formation 2
- Estrogen receptors in the forebrain are associated with cognitive function 2
Clinical Implications
What to Tell Patients
These symptoms are real and commonly reported, but they typically improve over time as the body adjusts to new hormonal levels. 3, 5 Women should be reassured that experiencing forgetfulness and word-finding difficulties during menopause is common and does not indicate dementia or permanent cognitive decline. 4
Assessment Approach
Look specifically for: 2
- Frequency and severity of vasomotor symptoms (hot flashes, night sweats)
- Sleep quality and duration - disrupted sleep is a major contributor to cognitive complaints
- Mood symptoms - depression and anxiety screening
- Impact on daily activities and quality of life
Treatment Considerations
Hormone therapy is NOT recommended for treating cognitive symptoms alone. 6 Higher-quality guidelines specifically recommend against using hormone replacement therapy to treat cognitive symptoms. 6
Instead, address the underlying contributors: 4, 7
- Treat vasomotor symptoms (which improves sleep, which improves cognition)
- Address mood disturbances with appropriate interventions
- Optimize sleep hygiene
- Consider mind-body interventions (cognitive behavioral therapy, mindfulness, yoga) which have empirical support for improving menopause-related quality of life 3, 7
Critical Caveat
Patient-reported cognitive symptoms (forgetfulness, difficulty with concentration, word-finding difficulties) rarely correlate with objective neuroimaging studies and neuropsychiatric testing. 2 This means women may feel more cognitively impaired than they actually are on formal testing, likely due to the combined effects of sleep disruption, mood changes, and the stress of managing multiple menopausal symptoms simultaneously.
