Post Concussion Syndrome Treatment
There are many people living with post concussion syndrome, and most don’t know that there are things they can do to support their body to heal. Post concussion syndrome is a result of unresolved physiology that occurred because of a concussion injury. And this can be treated. If your symptoms have persisted beyond the expected recovery window, there is a reason. This is where we find it and address it.
What is Post Concussion Syndrome?
Post concussion syndrome (PCS) describes the continuation of concussion symptoms beyond the expected recovery period, generally defined as three months, though many people live with symptoms for years or decades. Research estimates that between 15 and 30 percent of people who sustain a concussion will develop PCS, although it is likely much higher.
The symptoms are wide-ranging and can include persistent headache, brain fog, fatigue, sleep disruption, mood changes, gut issues, light and noise sensitivity, hormonal dysregulation, and cognitive difficulties. What connects them is not a single injury site but a systemic cascade of physiological disruption that has not resolved.

Why Symptoms Persist…
When the brain is injured, the body responds immediately. Immune cells in the brain activate to contain the damage. The lining of the gut becomes more permeable. Blood flow shifts. Stress hormones change. This is the body doing exactly what it is designed to do after trauma.
The problem is when this response does not always switch off.
In a straightforward recovery, the initial inflammatory response settles, the gut lining repairs, hormones stabilise and the brain gradually restores normal function. In post-concussion syndrome, one or more of these systems stays disrupted. And because they are all connected, a disrupted system in one area keeps the others from settling.
Here is how the cycle works in practice. The gut becomes more permeable after head injury, allowing substances into the bloodstream that the immune system treats as a threat. This keeps the brain's immune cells in a state of activation. Those activated immune cells sustain inflammation in the brain. That inflammation interferes with the systems governing sleep, stress and hormonal balance. Disrupted sleep undermines the brain's ability to clear inflammatory waste overnight. Hormonal disruption affects energy, mood and cognitive function. And the whole cycle continues, each part feeding the next.
This is why rest does not resolve post-concussion syndrome. It is also why treating one symptom at a time rarely produces complete recovery. The systems driving your symptoms are connected. They need to be treated that way.

The Naturopathic Approach to Post Concussion Syndrome
Naturopathic concussion care addresses the specific physiological mechanisms driving persistent symptoms. Treatment is personalised to your injury history, current presentation, and the systems most affected. The clinical framework used at The Concussion Naturopath includes:
Neuroinflammation resolution
Targeted herbal and nutritional compounds that support microglial regulation and resolution of chronic low-grade neuroinflammation. The kind you can’t see on scans, but we know it’s there, we see it posthumously in CTE.
Mitochondrial support
Supporting cellular energy production in brain and peripheral tissues to address the neurometabolic deficit that follows injury. The mitochondria are the energy powerhouse of cells, and they take a real hit in concussion injuries and addressing their optimal functioning is key to moving through post concussion syndrome
Nutrition and Lifestyle strategy
Anti-inflammatory nutritional protocols, blood glucose regulation and targeted nutrient repletion to support recovery conditions and to address specific needs. Paired with lifestyle strategies that support recovery, nervous system regulation and return to your normal activities.
Gut-brain axis restoration
Assessment and treatment of intestinal permeability, dysbiosis and gut-derived immune signalling that amplifies neuroinflammation. The very bacteria living in your gut matters greatly when it comes to concussion injuries and post concussion syndrome.
HPA axis and hormonal support
Addressing cortisol and other hormonal dysregulation, post-traumatic pituitary dysfunction and the downstream hormonal consequences that affect energy, mood and sleep. Everything is connected and nothing is random - and when your communication channels (hormones) are disrupted the body struggles to heal and rebalance.
Functional testing
Where clinically relevant, functional testing guides treatment including gut microbiome assessment, and comprehensive pathology inflammatory markers and hormonal panels. Clinical questioning and assessment can give a great deal of information, but we take a ‘test - don’t guess’ approach where deeper insight is required, as so often is the case in post concussion syndrome
The short answer is no, it’s never too late. People often assume that because time has passed, the window for meaningful recovery has closed. That is not how this works. The underlying mechanisms driving your symptoms, the ongoing inflammation, the gut disruption, the hormonal shifts, do not become untreatable simply because they have been present for a long time. They become the new normal for your body, but normal is not the same as permanent.
What does change with time is the clinical picture. Someone presenting two months post-injury looks different to someone presenting two years in, and the approach reflects that. But the same systems are at play. And those systems respond to treatment regardless of how long they have been dysregulated.
A significant proportion of people who come to The Concussion Naturopath have been symptomatic for years. Some for decades. The length of time since injury does not determine whether recovery is possible. It shapes how we approach it.
The body is capable of a great many things, when given the right conditions.

FAQs
How long does post concussion syndrome last?
1
Duration varies depending on injury history, health status, treatment approach and how quickly targeted intervention is initiated. With appropriate multimodal treatment addressing the systemic mechanisms, meaningful recovery is achievable at any stage. Naturopathic care adds a crucial element to healing from post concussion that no other modality can offer - working systemically, with consideration for the entire health picture of the person and utilising cutting edge funcitonal testing, evidence based herbal medicine, supplements and dietary and lifestyle modifications. ~ Louise Cork, 2026
Research supports personalised, multimodality approaches that address the specific physiological drivers of symptoms rather than symptom management alone. Naturopathic care addresses neuroinflammation, gut-brain axis disruption, hormonal dysregulation and mitochondrial dysfunction as interconnected systems, in conjunction with consideration for your whole health history, genetics, and even the very bacteria living in your gut.
What is the best treatment for post concussion syndrome?
2
Yes. The physiological disruption driving persistent symptoms does not simply resolve with time. Treatment addressing the underlying mechanisms is effective regardless of how long symptoms have been present. It is always possible to improve health outcomes - the body has a remarkable capability to function when given the right circumstances, which is one of the cornerstones of naturopathic practice.
Can post concussion syndrome be treated years after injury?
3
Do I need a referral for post concussion syndrome treatment?
4
No referral is required. All consultations are delivered via telehealth, available Australia-wide and internationally, please just check with us for availability internationally.
Can I see a Naturopath alongside my other practitioners?
5
Yes. Naturopathic concussion care is designed to work alongside your GP, physiotherapist, neurologist, neuropsychologist or any other treating practitioners. It addresses the systemic layer that other disciplines cannot treat. Communication with your team is welcomed and supported. A multimodality approach to concussion recovery is well supported by research.
