CTE Education
Start Here: CTE Education Guide
Plain-language guidance for families and caregivers learning about Chronic Traumatic Encephalopathy (CTE), early warning signs, behavior changes, overlap conditions, and caregiver support.
This page organizes RNA's full CTE education library into clear topic groups so you can start where you actually need to, without sorting through a long list of articles alone.
Start where you are
Important context: CTE cannot currently be definitively diagnosed during a person's lifetime. Many symptoms overlap with traumatic brain injury, PTSD, depression, sleep disorders, medication effects, and other neurological conditions. This education guide is designed to help families understand patterns and ask better questions. It is not a diagnostic tool and does not replace evaluation by a qualified medical professional.

Start here if you want to understand what CTE is, who may be at risk, how exposure is studied, and why so much public confusion surrounds this condition.

Not sure where to start?
Most families do best starting with the basics, then moving into early warning signs, then caregiver support. You do not need to read everything at once. Start with one section and go from there.
