If noise, light, or touch have become suddenly unbearable, your perimenopause hormones are likely the reason. Declining estrogen disrupts the brain's sensory gating system — the filter that decides which inputs to amplify and which to suppress. When estradiol falls, GABA activity drops and sensory neurons fire more easily. This article explains the neuroscience, covers all five affected sensory channels, and outlines the evidence-based approaches that actually help — from env

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.

The feeling that you've lost yourself during perimenopause is not a personality crisis or a midlife cliché — it's a neurobiological event. Declining estradiol disrupts the brain's dopamine reward system and serotonergic circuits simultaneously, reducing motivation, blunting the sense of purpose, and creating the lived experience of not recognising yourself. This article explains the mechanism, the evidence, and the specific interventions that can help restore the disrupted sy

If old memories, buried grief, or feelings you thought you had dealt with are flooding back in perimenopause, this is not a breakdown. Estrogen directly regulates the amygdala — the brain's fear centre — and supports the prefrontal cortex's ability to suppress threatening memories. As it fluctuates and falls, your brain's buffer weakens, your window of tolerance narrows, and trauma that was held in place by hormonal stability can surface. The science explains why. What helps

Women are 40% more likely to develop depression during perimenopause — even with no prior mental health history. Estrogen withdrawal disrupts serotonin, dopamine, and GABA simultaneously: the three systems your brain relied on for emotional stability your entire adult life. Anxiety, rage, grey heaviness, and 3am dread are not a breakdown. They are neuroscience. Here's the hormonal mechanism, the window of vulnerability science, and the evidence-based protocol that actually he
