The Chronos Diagnostic Review asks why your symptoms persist and whether recovery is possible.
Most clinics ask what your symptoms are. We ask whether recovery is possible.
Most clinics ask what your symptoms are. The Chronos Diagnostic Review asks why your persist, which systems are generating them, and what your recovery potential is.
Chronic and complex conditions are rarely the product of one single cause, system, or missed diagnosis. They are the accumulated expression of multiple dysregulated systems — interacting, reinforcing, and compounding across months and years.
Standard medical assessment is not designed to map that complexity. A GP appointment captures a presenting complaint. A specialist referral addresses a single system. Investigations confirm or exclude structural pathology. What none of these reliably capture is the full picture of how a person's nervous system, metabolic function, immune regulation, breathing mechanics, movement capacity, and psychological architecture are collectively driving their symptoms. That is precisely what the Chronos Diagnostic Review is designed to do.
Before any assessment begins, one clinical principle shapes everything at Chronos: the significance of chronicity. When persistent symptoms extend beyond twelve weeks, they are no longer simply acute processes that have lingered. They represent established patterns of multi-system dysregulation — neural pathways reinforced by repetition, metabolic environments adapted to dysfunction, nervous systems calibrated to sustained threat. Reversing these patterns requires sustained, structured, multi-system input over time.
Twelve weeks is not an arbitrary timeframe length. It is the minimum amount of time required to establish foundational regulation across all six recovery systems simultaneously. Less than that, and the neurological and metabolic retraining that genuine recovery demands cannot take root.
The Chronos process begins before the first conversation takes place. Every prospective client completes a detailed pre-consultation screening evaluation — the most comprehensive intake assessment in virtual chronic condition care. It maps red flags, nervous system function, neuroplastic indicators, physical health and movement capacity, metabolic status, immune system function, infection history, psychological architecture, and full clinical history across every relevant dimension.
This is not a symptom checklist. It is a systems-level clinical map — designed to identify not just what a person is experiencing, but which systems are driving it, how they are interacting, and what the recovery landscape actually looks like. The completed screening is analysed in detail before the first appointment takes place. By the time client and clinician meet, the clinical picture is already forming.

The Chronos Diagnostic Review is a 75-minute consultation — structured, unhurried, and clinically substantive in a way that no standard appointment allows.
It begins with a detailed review of the screening findings — feeding back what the evaluation revealed and where the key system dysregulations lie. It then moves into deeper clinical exploration of the client's condition, history, and recovery context — the layers that no screening form alone can capture. By the close of the consultation, two things are established with clarity.
First, a clinical assessment of recovery potential — an honest, evidence-informed evaluation of what recovery, relief, or remission looks like for this individual, and what the pathway toward it requires.
Second, eligibility for a Chronos recovery programme — specifically, which of the four symptom-specific pathways is most appropriate, and which of the three complexity tiers reflects the depth and duration of support the case requires. Complexity tier determines session frequency across the 12-week process — ensuring that the most complex or long-standing cases receive the clinical intensity their recovery demands.
Chronos accepts only cases where relief, recovery, or remission is genuinely considered possible. This is not a threshold designed to exclude — it is a clinical commitment to integrity. Every person who enters a Chronos programme does so with a clinician who believes recovery is within reach.
“As soon as I completed my screening form, I knew Chronos was different to anything I'd tried before. They ask questions nobody had ever asked me, which brought a sense of relief I wasn't expecting.”
The Chronos Diagnostic Review provides a structured multi-system baseline assessment across neurological, metabolic, immunological, respiratory, and behavioural domains — with a documented recovery pathway and programme recommendation. GP correspondence is provided on request. The process is fully virtual, globally accessible, and appropriate for complex, long-standing cases where single-system approaches have not produced sustained outcomes.
