Concussion care is moving beyond rest and guesswork
How do concussions affect the brain?
The episode explains why concussion can disrupt brain function without obvious structural damage, while long-term risks and access to care remain uneven.
- 1Concussion primarily disrupts brain connectivity and energy use, making symptoms real even when scans show no obvious structural injury.
- 2CTE research raises serious concerns, but clinicians still lack reliable tests for predicting individual long-term risk in living patients.
- 3Active recovery emphasizing guided activity, nutrition, sleep, and holistic care has replaced prolonged isolation for many concussion patients.

Teena Shetty replaces the familiar concussion cocoon with a practical recovery model built around guided activity, nutrition, sleep, and holistic care.
The brief
Neurologist Teena Shetty opens with the gap between alarming CTE findings in football and the limited ability to predict who will develop lasting problems.
Shetty explains concussion as a functional disruption of brain connectivity, metabolism, and neurotransmitters—an injury that can be severe even without obvious structural damage.
The episode contrasts coordinated care for professional athletes with ordinary patients’ need to self-advocate, especially when symptoms are invisible and testing has limits.
Treatment has moved beyond the concussion cocoon: guided activity, adequate protein, sleep, and selected medications support recovery after dangerous complications are ruled out.
Shetty’s broader argument is that recovery must address identity, personality, daily life, and mental well-being—not just the initial neurological injury.
