Antivirals (Paxlovid, Ensitrelvir)
Mixed results in trials. The virus is already gone in most Long COVID patients.
You've been told it's anxiety. That your tests are normal. That you just need more rest. We see what others miss: measurable brain dysfunction that responds to targeted treatment.
The infection cleared months ago, but you're still not yourself. The brain fog that makes simple tasks feel impossible. The crushing fatigue that sleep doesn't fix. The frustrating moment when you can't find the right word.
Despite billions in research funding, clinical trials keep failing. The treatments that should work, don't.
The RECOVER-NEURO trial, published in JAMA Neurology in January 2025, tested three evidence-based rehabilitation approaches across 328 patients at 22 sites.[1]
None of them demonstrated meaningful improvement over placebo.
Computerized brain training failed. Cognitive behavioral rehabilitation failed. Transcranial direct current stimulation failed. And this isn't an isolated finding. Trials of antivirals and anti-inflammatories have produced similarly disappointing results.[2]
Mixed results in trials. The virus is already gone in most Long COVID patients.
Eight randomized controlled trials show "no effect" on quality of life, cognition, or fatigue.[3]
Without imaging guidance, these programs can't target your specific dysfunction patterns.
Research from Johns Hopkins, the UK Biobank study, and imaging centers worldwide has documented measurable brain changes that persist long after viral clearance.[4]
Blood vessels fail to deliver oxygen where neurons need it. Brain regions become starved of resources, forcing inefficient compensation patterns that cause fatigue and brain fog.
PET and fMRI studies show activated microglia and reactive astrocytes across multiple brain regions, persisting long after viral clearance.[5]
The balance between "fight or flight" and "rest and digest" systems becomes disrupted, causing palpitations, temperature issues, dizziness, and POTS.
The landmark Douaud et al. study in Nature documented reduced grey matter thickness and tissue damage in frontal and memory areas.[6]
Our free consultation helps determine if your symptoms match the patterns we've successfully treated in thousands of patients.
Schedule Free ConsultationIt might seem unusual. But peer-reviewed research shows Long COVID and post-concussion syndrome cause remarkably similar brain dysfunction.
Peer-reviewed data shows substantial overlap across all major cognitive symptoms
The overlap isn't a coincidence. Both conditions involve the same underlying brain dysfunction: disrupted neurovascular coupling, neuroinflammation, and autonomic dysregulation.
A 2024 direct comparison study found no statistically significant differences in psychological functioning between the two groups.[7]

Unlike generic rehabilitation programs, we use functional brain imaging to identify your specific dysfunction patterns and design treatment that targets them directly.
Our specialized fMRI protocol measures brain function across 56 regions while you perform cognitive tasks. The scan produces over 7,000 images revealing exactly which areas are underperforming and which are overcompensating.
One intensive week of multidisciplinary therapy targeting your specific dysfunction patterns. Neuromuscular, cognitive, vision, vestibular, sensorimotor, autonomic regulation, and psychotherapy are sequenced to maximize neuroplasticity.
A follow-up fNCI scan objectively documents changes in brain function. You'll see the before-and-after comparison yourself, with clear evidence of your progress.
The RECOVER-NEURO trial used generic, non-personalized rehabilitation. Participants received the same treatments regardless of their specific brain dysfunction patterns.
Our approach is fundamentally different:
The majority of patients who complete our program report meaningful improvement in their symptoms.
Our outcomes have been independently validated by researchers at the University of Groningen, representing rare third-party verification in the neurorehabilitation field.
See If You're a CandidateIf you're struggling with persistent symptoms after Lyme disease treatment, you're facing a remarkably similar challenge to Long COVID patients.
A 2022 Johns Hopkins study found that 14% of Lyme patients who were diagnosed early and treated promptly still developed lasting symptoms.[13]
Why antibiotics can't fix PTLD: Northwestern University research (2025) shows bacterial cell wall fragments accumulate in tissues and continue triggering inflammation long after live bacteria are eliminated. More antibiotics can't clear debris that isn't alive.[14]
Long COVID and Lyme disease are examples of a pattern that has repeated throughout medical history. Various infections can trigger lasting brain dysfunction.
We also work with patients experiencing lasting cognitive symptoms from:
If an infection has left you with persistent cognitive symptoms and standard treatments haven't worked, our imaging-guided approach may help.
We carefully screen all potential patients to ensure we only accept those we believe we can help. Not everyone is a candidate, and we'll be honest about whether our approach is likely to work for your situation.
You may be a good candidate if:
You've been dismissed, misunderstood, and told your symptoms might be psychological. We see the measurable brain dysfunction these conditions cause. We have the imaging to prove it. And we have a track record of helping patients reclaim their cognitive function and their lives.
