The crash ends in seconds. The rest takes years.

What happened

Clipped by a right-turning car on a familiar route home. He wasn't wearing a helmet — he'd left it at work that morning. Loss of consciousness at the scene, moderate TBI diagnosed in the ER.

The long tail

• Six months off work; returned part-time for another year.
• Persistent short-term memory issues — still uses lists for everything.
• Diagnosed with post-injury depression 14 months later.
• Chronic light and noise sensitivity; migraines several times a month.

What happened

Rear-ended at a red light. Airbag didn't deploy. She walked away, refused an ambulance, went to urgent care two days later when the headaches wouldn't stop.

The long tail

• Nine months of post-concussion syndrome: brain fog, word-finding trouble, exhaustion.
• Had to drop from full-time graduate study; took an extra year to finish.
• Anxiety around driving that took cognitive behavioural therapy to unwind.
• Now an outspoken advocate for taking mild TBI seriously.

What happened

Fell from scaffolding onto a concrete edge. Severe TBI, two-week ICU stay, months of inpatient rehab. Hard hat was on-site but not on his head.

The long tail

• Permanent changes to executive function; can no longer run a crew.
• Retrained into a desk-based estimating role after two years off.
• Marriage strain; couples counselling for the mood changes and irritability.
• Volunteers at a local BI association support group every second Saturday.

What happened

Two mild concussions in one season, cleared to play too quickly each time. A third hit in the playoffs led to a longer, harder recovery — a suspected second-impact effect.

The long tail

• Retired from contact sport at 17.
• Return-to-learn took a full semester; grades slid before school accommodations kicked in.
• Depression and identity loss common in young athletes who lose their sport.
• Now studies kinesiology and speaks in classrooms about concussion protocols.
