Maybe it's not all in your head
Rethinking postpartum depression as a neuroimmune condition
I am 18, sat on the sofa with a small bowl of crisps in one hand and tissues in the other. It’s the day my brain started building a pathway to a thought that would haunt me for years. My screen shows De Gelukkige Huisvrouw (The Happy Housewife), a Dutch film starring Carice van Houten as Lea, that explores postnatal depression (PND).
Unsure whether I was more afraid of what might come after having a baby, or of what may have already unfolded in our home after my mother had us, the story of Lea and her baby Harry Jr really stuck. I imagine I’m not alone: the film won a Platinum Film Award and refreshingly broke the taboo that mothers can experience violent or ‘unnatural’ thoughts toward their children. Sometimes, this is part of PND. The lived reality for at least 15% of new mothers.
Lea’s plot thickens, and it later becomes clear her experience is actually postnatal psychosis. A diagnosis that, while it can overlap with PND, is less common (it ‘only’ affects 1 in 500–1000 people postpartum), and often confused with the clinical picture of what Postnatal Depression must look and feel like. An intense black hole where the mother loses her identity and finds herself physically unable to alchemise it into bonding, into secure attachment with this new, shared life.
Word of mouth also commonly abbreviates PND to ‘postpartum’. Leaving new mothers to think they’re probably ‘not postpartum’ because they haven’t experienced a breakdown, have moved past the baby blues, that day 3–5 sadness. They conclude their self-care without ever looking into the many adjustments the body navigates chronologically for at least the first year after birth (and in Āyurveda, up to two years—a timeline modern medicine is increasingly supporting when it comes to hormonal and nutritional recovery).
Now here’s the catch:
If one does feel ‘postpartum’, the general consensus {which, until very recently, included my own} is still that this is largely a mental health issue. A referral to counselling, or to organisations like PANDAS, is often presented as the mother’s best path to healing.
But what if that's not the whole story?
A growing body of research is now increasingly understanding postpartum depression as a (here it comes…) Neuroinflammatory event. Yep! A condition with biological roots as tangible as the swell of a sprained ankle.
The pathology starts with activated immune pathways, leading to oxidative damage, and culminating in stress responses in the brain that reduce the readily available serotonin. And that scarcity feels blue.
1. Brain Inflammation and Immune Cell Activation
When systemic inflammation reaches the brain, it activates microglia and astrocytes. These are your brains ‘resident’ immune cells. These cells, meant to protect, become overactive and begin releasing inflammatory signals within brain regions critical for mood regulation.
”Music exposure reduced levels of proinflammatory factors (IL-6, IL-1β, iNOS, TNF-α, and TGF-β) and the activation of microglia and astrocytes in these brain regions.” (1)
Imagine: the brain’s peaceful neighbourhood watch becoming agitated, knocking on every door, spreading alarm instead of calm.
2. Synaptic Plasticity Disruption
Inflammation and oxidative stress don’t just affect mood. They physically alter brain structure by damaging synaptic plasticity (the brain’s ability to form and maintain connections between neurons that is).
“Transcriptomic sequencing of hippocampal and prefrontal cortex tissues supported our findings, revealing that differential gene expression is primarily involved in regulating synaptic plasticity.” (2)
Recent research confirms that treatments which restore synaptic plasticity, mitigate oxidative stress, and reduce inflammation can effectively alleviate depressive behaviours.
Imagine: The forest paths between trees become overgrown and blocked. Messages can’t travel easily from one part of the mind to another.
3. The Kynurenine Pathway: A Tryptophan Tragedy
A particularly elegant mechanism involves the kynurenine pathway. Inflammation diverts tryptophan (the precursor to serotonin, our “peace and happiness” molecule) away from serotonin production and toward the production of neurotoxic metabolites (3).
And here’s where this takes us:
Lower serotonin: Less of the chemical that makes us feel happy while eating chocolate, without eating chocolate
Higher neurotoxins: More brain-damaging compounds
Imagine: A river meant to flow toward peaceful meadows is diverted toward barren, toxic lands. The meadows dry up; the toxins accumulate downstream. Ykes!!
So maybe we shouldn’t keep PANDAS under speed dial?
An emotional anchor (peer support, counseling, meditation) remains a priority because the experience of neuroinflammation is traumatic. But we've got to marry it with a medically sound physical plan.
Because we now understand PPD through this lens, researchers are actively exploring gentle, natural interventions:
“Due to the blood brain barrier, many drugs exhibit poor therapeutic efficacy and potential adverse effects... Therefore, prevention of postpartum depression is crucial, necessitating the development of more effective, side effect-free prevention strategies.”
This includes:
Music therapy (shown to normalise oxidative stress indicators and reduce proinflammatory factors… Hello, sound healing!) (4)
Traditional herbal formulations (like Sugemule-7, which alleviates oxidative stress and neuroinflammation. I'll elaborate on herbs for your Āyurvedic pantry soon). (5, 6)
Nutritional interventions that boost antioxidants and anti-inflammatory compounds (7).
Your Āyurvedic Pantry
As I sit with these new insights, various Āyurvedic formulae are taking shape in my mind's eye. Promisingly, we can now get our hands on Āyurvedically aligned superfine Pearl powder through Na'vi Organics—a remedy the Vedas framed as the embodiment of the 'Universal Mother', while doubling as a potent mental health support when harvested from divine sources and paired with Sandalwood.
Also worth exploring: an alkaline diet, turmeric milk, and liposomal glutathione.
Your specific approach will, as always, depend on your Dosha. So before I sign off, here's some food for thought. It’s a lens through which to wonder which metabolic type might fit any PND symptoms you or a loved one have faced:
Pitta-type PND manifests as inflammatory, agitated, perfectionistic, burnout depression
Vata-type PND manifests as anxious, fearful, exhausted, depleted depression
Kapha-type PND manifests as heavy, withdrawn, sluggish, numb depression
Each Dosha can experience PND, but the expression of depression: its symptoms, its root cause, and its treatment, will look different depending on the mother’s constitution and the Dosha that has fallen out of balance.
Watch this space. I’ll report back soon with a formula that is as poetic as it is potent for systemic neuroinflammation, all while safe for the breastfeeding dyad.
Signing off with gratitude,
