Why You Don't Easily Forget How to Ride a Bicycle
Riding a bike is stored as implicit, procedural memory in the cerebellum and basal ganglia — areas more protected from TBI than memory centers responsible for facts and dates.

Legal and medical guidance for traumatic brain injury victims in Colorado. Written by Attorney Dan D'Angelo.
A brain injury is commonly referred to as an invisible injury, and individuals with brain injuries often lack awareness of their injury and where to find answers. This can cause delay in medical treatment and legal representation. Bike Brain Law's mission is to help brain injury victims find help and a trusted legal advocate.

Riding a bike is stored as implicit, procedural memory in the cerebellum and basal ganglia — areas more protected from TBI than memory centers responsible for facts and dates.

Studies estimate 40–50% of mild TBI patients leave the ER without a documented TBI diagnosis. You may still have a valid claim — here's why.

The right questions to ask before hiring a TBI attorney — including experience with normal imaging, missed ER diagnoses, and insurance challenges.

T1, T2, FLAIR, fMRI, SWI, DTI, MRS, ASL — different MRI techniques look at different brain components. Why this matters for proving a TBI.

Imaging sensitivity, slice thickness, and timing all matter. A 'normal' scan does not mean no TBI occurred — particularly for mild TBI and concussion.

No. TBIs — especially mild ones — are diagnosed using clinical factors like loss of consciousness, post-traumatic amnesia, and Glasgow Coma Scale.

Loss of consciousness is only one of several diagnostic factors. Amnesia, altered mental state, neurological deficits, and intracranial lesions also matter.

Coup-contrecoup injuries, rotational forces, whiplash — the brain can be damaged inside the skull even without direct head impact.

Mild, moderate, severe, complicated mild — TBI severity classification is evolving. The new CBI-M framework aims to better reflect real outcomes.

TBI is often called the 'invisible injury.' Symptoms may overlap with other conditions, be delayed, or be masked by pain from other injuries.

A complete list of physical, cognitive, communication, and behavioral symptoms — plus the clinical signs doctors look for to diagnose a TBI.

Traumatic vs non-traumatic, primary vs secondary injury, diffuse axonal injury — a foundational guide to how brain injuries occur and evolve.

A bicycle helmet's protective lifespan is limited. Replace it after any crash, visible damage, fit changes — or every three to five years with regular use.
