Post-concussion syndrome

What is post-concussion syndrome?

Post-concussion syndrome describes symptoms from a concussion that persist well beyond the typical expected recovery window, rather than resolving within the first weeks as most concussions do.

While many concussions resolve within a few weeks, a meaningful minority of cases develop this more prolonged, persistent symptom pattern extending for months or, in some cases, longer.

The condition remains functional rather than structural, meaning standard imaging studies frequently continue to appear normal despite genuine, significant ongoing symptoms and impairment.

This persistent gap between normal imaging and genuine, significant impact on daily functioning is precisely what makes these claims especially challenging to present effectively.

What symptoms characterize this condition?

The symptom pattern generally mirrors acute concussion symptoms but extends well beyond the typical expected recovery window.

• Persistent headaches, often different in character from the person's prior baseline
• Ongoing difficulty concentrating and genuine cognitive fog
• Continued dizziness and balance difficulties
• Sleep disruption that persists well beyond the initial injury period
• Mood changes, including increased irritability, anxiety or depression
• Sensitivity to light and noise that continues over an extended period

Why are these claims particularly challenging to present?

Because there is generally no single objective test confirming the diagnosis, and standard imaging frequently appears normal despite the genuine, significant reported impact on daily functioning.

This absence of a single, definitive confirming test makes these claims a frequent and predictable target for defense arguments regarding genuine severity, malingering, or unrelated causation.

Neuropsychological testing can provide more objective, measurable documentation of specific cognitive deficits, which helps considerably in building a more persuasive, less purely subjective case.

How is a claim involving this condition actually built?

Through consistent documentation from treating providers over time, showing a genuine pattern of persistent symptoms rather than an isolated, one time complaint.

Testimony from family, friends and coworkers describing specific, concrete changes they have personally observed carries genuine weight, since these are the people positioned to notice what has actually changed.

Neuropsychological testing, where appropriate, provides more objective measurement of specific cognitive deficits than symptom reporting alone can offer.

Common questions

How long do symptoms typically last with this condition?

This varies considerably by individual, ranging from several months to, in some genuinely persistent cases, considerably longer, and a specialist can help assess your own specific situation and trajectory.

Why does my imaging keep coming back normal despite my ongoing symptoms?

This is expected and does not disprove your condition, since it remains a functional rather than structural injury that standard imaging generally cannot directly detect or visualize.

Can this condition meet New Jersey's verbal threshold?

This is possible where supported by strong documentation, including neuropsychological testing and a clear physician opinion on permanency, though it is generally more challenging to establish than an injury with a clear imaging finding.
