Your mind in menopause

Let’s talk brains. Specifically, how your brain rewires itself during perimenopause. It’s real, it’s chemical, and no, it’s not just “in your head” (though it is happening in your head). Hormonal changes during menopause can affect the brain’s structure and function, which often lead to mood changes, memory lapses, and changes in behaviour effecting your mental health. These neuropsychiatric symptoms are real, serious – but absolutely manageable with the right support.

What are the neuropsychiatric symptoms in perimenopause?

This is the all-star lineup of cognitive and emotional shifts triggered by hormonal fluctuations:

• Brain fog – Like someone dimmed the lights in your head.
• Memory lapses – Short-term recall takes a casual leave of absence.
• Poor concentration – Attention span: now buffering.
• Mood swings – From zen monk to rage squirrel in 3.5 seconds.
• Anxiety and depression – Emotional states that appear like surprise software updates.
• Insomnia and panic sessions – Your brain decides 2am is ideal for a full existential audit.

These symptoms can be unsettling. But don’t panic: this is biology, not burnout. That said, if these symptoms feel overwhelming or persistently interfere with daily life, consult a healthcare professional – especially if you’re experiencing severe mood disturbances or anxiety.

Why does this happen?

During perimenopause, oestrogen and progesterone – the hormonal co-pilots for your neurotransmitters – start ghosting your brain. Oestrogen affects:

• Serotonin (mood regulation)
• Dopamine (motivation and pleasure)
• Acetylcholine (memory and learning)

When oestrogen levels dip or spike, these brain chemicals get thrown into disarray. Sprinkle in poor sleep (thanks, night sweats) and cortisol overload your mental bandwidth shrinks faster than your patience when someone breaths too loudly.

Scientific studies confirm menopause alters brain structure, connectivity, and metabolism—including how your brain handles memory and even amyloid-beta, a protein linked to Alzheimer’s disease (Mosconi et al., 2021). While this doesn’t mean menopause causes dementia, the research is ongoing and complex, it does show just how important oestrogen is to brain energy metabolism and resilience. It’s not to scare you, it’s to show you: this is real, but it can be managed.

What can help (it’s not just yoga and tea)

Here’s what science (and experience) says can help bring your brain back online. Please consult your healthcare provider before starting any new treatments or supplements, especially if you have underlying health conditions or take other medications.

Medical options

• HRT (Hormone Replacement Therapy): Replaces missing hormones and commonly prescribed to help some women manage symptoms such as mood changes, sleep disruption or cognitive difficulties. Suitability depends on your personal and family medical history.
• SSRIs (e.g. paroxetine, fluoxetine): Are sometimes prescribed to help manage anxiety, low mood or hot flushes.
• Gabapentin: For treatment-resistant anxiety (NICE-approved, 2024 update).

Non-Medical options

• CBT (Cognitive Behavioural Therapy): Proven to reframe anxious thoughts and improve resilience.
• Strength training: Helps regulate cortisol and boost brain-derived neurotrophic factor (BDNF).
• Yoga/Pilates: Calms the nervous system, improves balance (literal and emotional).
• Cut smoking and alcohol: Both disrupt neurotransmitter function and impair sleep quality.

Nutrition & supplements

• Magnesium (glycinate or threonate): Calms the mind and supports memory.
• B Vitamins (B6, B9, B12): Fuel for brain function and emotional regulation.
• Omega-3 fatty acids: Anti-inflammatory support for mood and cognition.
• Rhodiola Rosea & L-theanine: Adaptogens that combat stress and enhance mental clarity.
• Phytoestrogens (soy, flaxseed): Gentle oestrogen support from plants.

Effectiveness of supplements vary between individuals and aren’t suitable for everyone, particularly where other treatments or medications are involved.

Final thoughts

If your brain feels like it’s been swapped for a slower, sadder, more anxious version, know this: it’s not permanent, it’s not a character flaw, and it’s not all in your head. It is in your brain chemistry, and that means there are tools (science-backed tools!) to help can navigate the hormonal haze and reclaim your cognitive spark.

So repeat after me: It’s the hormones. I’m still me. I just need better WiFi up there – and maybe some magnesium.
