WHAT IT’S REALLY ABOUT
Micky Collins: Concussions Are Treatable With Targeted Active Therapy, Not Rest
- Collins describes concussion as a cellular energy crisis, with potassium leaking out and calcium flowing in, causing a supply-demand mismatch without structural damage or cell death, and says there is no biomarker or imaging that can diagnose it.
- He says concussion has six overlapping types (cognitive fatigue, vestibular, ocular, migraine, anxiety, and neck), and that matching treatment to the type is the key to recovery.
- Collins argues against rest and for active, exposure-based treatment: vestibular and ocular retraining, aggressive exertion, regulated sleep, and exposure to busy environments, with medications used only if behavioral treatment falls short.
- He reports that early specialist care, ideally within seven days, best predicts recovery, that playing through symptoms adds substantial recovery time, and that even chronic cases from years earlier can usually be treated.
- The conversation also covers hyperbaric oxygen and ketones, CTE and dementia risk, APOE4, concussions in older adults, and the need for more concussion specialists and fellowship programs.
IDEAS WORTH REMEMBERING
5 ideasConcussion is a functional energy problem, not structural damage
Collins says stretched neuronal membranes cause potassium efflux and calcium influx, creating a mismatch between energy demand and supply, with no cell death and nothing visible on MRI, PET, EEG, or blood tests.
Dizziness and fogginess predict worse outcomes better than loss of consciousness
Collins says on-field dizziness is six times more predictive of a month or longer recovery than any other symptom, with fogginess second, whereas loss of consciousness is not the best predictor.
Playing through symptoms lengthens recovery substantially
In the retrospective study Collins describes, kids removed immediately recovered in about 18 days versus 44 days for those who played 15 more minutes, and a follow-up found roughly seven to eight extra days per minute.
Treatment is active and targeted, not rest
Collins says rest makes things worse; he prescribes vestibular and ocular retraining, aggressive exercise, regular sleep, and exposure to busy environments matched to each patient's concussion type.
Pre-existing vulnerabilities shape who gets concussed and how
Collins says histories of car sickness, migraine, lazy eye, or anxiety mean less force causes injury and steer patients down the corresponding pathway, and that girls are more vulnerable.
WORDS WORTH SAVING
5 quotesRather, Peter, and this is important, concussion fights dirty. Like, whatever you bring to the table that's weak seems to be affected more
— Micky Collins
too much awareness without a solution is called hysteria, and we see that happen with this injury.
— Micky Collins
So for every minute you try to play through your injury, you add on, like, seven or eight days of recovery.
— Micky Collins
You're exactly right, and you're absolutely wrong in how we approach this injury.
— Micky Collins
So just because you're a neurologist doesn't mean you know concussion. Just because you're a neurosurgeon doesn't mean you know concussion.
