Perimenopause intrusive thoughts aren't a sign of mental illness — they're a predictable neurological consequence of progesterone and estrogen withdrawal. When progesterone falls, so does allopregnanolone, the brain's primary GABA-activating calm signal. Simultaneously, declining estrogen disrupts serotonin pathways that normally interrupt looping thought patterns. This article explains the neuroscience and what the evidence actually shows works.

Perimenopause rage is neurological, not personal. Estrogen volatility disrupts the amygdala–prefrontal cortex circuit governing impulse control, while declining progesterone removes the brain's GABA-A calming buffer. This article covers the 2025 Menopause Society research on hormonal anger and which interventions — HRT, CBT, sleep, exercise — have the strongest evidence.
