Brain Fog, Irritability, and ‘I Don’t Feel Like Myself’: The Hormonal Rollercoaster of Perimenopause

Brain Fog, Irritability, and “I Don’t Feel Like Myself”

Perimenopause — the years leading up to menopause — is often more destabilizing than menopause itself. Cycles become unpredictable, ovulation becomes irregular, and hormone levels fluctuate wildly.

These ups and downs can affect not just the body but also the brain — triggering anxiety, depression, irritability, and cognitive fog. Many women describe it as “not feeling like myself” like their usual resilience has vanished.

But what’s really happening isn’t aging or burnout — it’s hormonal unreliability.

Loop Cycles and Hormonal Whiplash

During perimenopause, the brain and ovaries stop communicating as smoothly as they once did. The HPO axis (hypothalamic-pituitary-ovarian loop) starts to misfire, producing cycles that are too short, too long, or skipped altogether.

These “loop cycles” cause estrogen and progesterone to spike and crash unpredictably. Some months, estrogen soars without progesterone’s balance; others, both hormones drop too soon. The result? A biochemical rollercoaster that can wreak havoc on mood, cognition, and sleep.

Why Labs Can Look “Normal” Even When You Don’t Feel Normal

Here’s the tricky part — a single blood test might show “normal” hormone levels even when symptoms are severe.
That’s because hormones fluctuate daily, sometimes hourly. A normal-looking result doesn’t reflect what your brain is experiencing.

This disconnect often leads women to feel dismissed or told “everything looks fine,” even as they struggle with symptoms that profoundly affect their quality of life.

How Perimenopause Affects the Brain

Estrogen and progesterone regulate neurotransmitters like serotonin, dopamine, and GABA, which shape mood and cognition. When these hormones fluctuate:

  • Serotonin levels fall → irritability and anxiety rise
  • Dopamine drops → motivation and focus decline
  • GABA modulation weakens → sleep becomes restless, and calm feels out of reach

It’s a neurochemical storm — and one that can mimic depression or ADHD if the hormonal context is missed.

Finding Relief: Restoring Rhythm

Treatment during perimenopause focuses on stabilizing, not suppressing, hormone activity. Options may include:

  • Transdermal estradiol and micronized progesterone for physiologic replacement
  • SSRIs or SNRIs to buffer mood instability and anxiety
  • Lifestyle support: consistent sleep, resistance training, blood sugar regulation, and mindfulness

At Conscious Psychiatry, we address both the neurotransmitter and hormonal sides of the equation — because balance isn’t just emotional, it’s biological.
