In Detail
Cognitive complaints during perimenopause and menopause are common and well-documented. Women describe word-finding difficulty, trouble multitasking, slower mental processing, and short-term memory lapses. Research has confirmed measurable changes in verbal memory during the transition.
Estrogen plays an important role in brain regions involved in memory and executive function, including the hippocampus and prefrontal cortex. Sleep fragmentation, hot flashes, and elevated cortisol compound the cognitive picture. The good news: these changes are typically not progressive in the way dementia is. Most women stabilize or improve once hormones are addressed and sleep is restored.
A thorough evaluation rules out other contributors — thyroid dysfunction, B12 deficiency, sleep apnea, and medication side effects — before attributing brain fog to hormones alone.
