Perimenopause brain fog and memory: what is happening to you

Brain fog is real and it is one of the most-reported peri symptoms. Estrogen affects the brain areas that handle memory and word retrieval, so losing the word for "kettle" at 47 is biology, not early dementia.

What helps: write things down on paper before your phone (the act of writing builds the memory), one task at a time, and protect sleep; fog is dramatically worse on broken sleep. The good news: it typically improves after menopause, and many women report it lifts on hormone therapy. Mention it at your next appointment. It is a valid, documented peri symptom.
