    Monologue: Probable CTE - What We Know, What We Don't and Why the Words Matter

    Send us Fan Mail This episode unpacks what "probable CTE" actually means — where the term comes from, what the science can and can't currently tell us, and why a single case (former Socceroos captain Paul Wade) has reignited debate about diagnosing a disease that's only ever been confirmed after death. It walks through the genuine case for and against using this label in living patients, and why the language we use around it matters. Note: This episode is for educational purposes only and is not medical advice or a diagnostic tool. While I've done my best to accurately interpret the cited journal articles, please read the original sources yourself for full context before drawing conclusions.   06:00 - Segment One: What Chronic Traumatic Encephalopathy Actually Is   09:45 - Segment Two: Why You Can't Diagnose It in the Living — Yet   12:00 - Segment Three: "Probable CTE" — Where the Term Actually Comes From   17:09 - Segment Four: Why This Topic Divides Even the Experts — The Dose-Response Problem   21:30 - Segment Five: The Case For Diagnosing Probable CTE in Living Patients   24:00 - Segment Six: The Case Against — Or At Least, the Case for Caution   29:27 - Segment Seven: Why the Words We Use Actually Matter   32:50 - Segment Eight: Where This Leaves Us     Episode — Reference List 1.

    Concussion and Return-to-Drive with Dr Julianne Schmidt

    Send us Fan Mail Dr. Schmidt is the Georgia Athletic Association Endowed Professor at the University of Georgia and Co-Director of the UGA Concussion Research Center. Her research program focuses on the continuum of concussion management, including injury assessment, clinical recovery, rehabilitation strategies, and evidence-based return-to-activity protocols. She is particularly recognised for advancing the evidence surrounding post-concussion return-to-drive decision-making, an emerging area of clinical importance given the cognitive, visual, and motor demands of driving following mild traumatic brain injury. Her sustained contributions to concussion science were recognised in 2025 with her induction as a Fellow of the National Athletic Trainers' Association (NATA), one of the profession's highest distinctions. With more than 3,500 citations in the scientific literature, Dr. Schmidt's work has substantially influenced contemporary concussion research, clinical guidelines, and interdisciplinary approaches to patient care.   01:10 - Journey into Concussion and Return-to-Driving 05: 15 -What is a concussion? 06:50 - Why Don’t We Really Think of Concussion and Return-to-Drive? 09:00 – Drink Driving Paradox and Concussion 11:30 – Messaging Around Return-to-Drive 15:10 – What Does Return-to-Drive Protocols  21:00 – Development of Protocols  28:00 – Heavy Machinery  34:00 - Where to Find and Help Dr Julianne Schmidt’s Work    Twitter: @first concussion Facebook: Headfirst: A concussion podcast Instagram: Headfirst_ Concussion   Email: headfirstconcussion@gmail.com

    Return-to-Learn (RTL) and Concussion in Preforming Arts Populations with Dr Allyssa Memmini

    Send us Fan Mail Dr. Allyssa Memmini, PhD, LAT, ATC, is an Assistant Professor in the Department of Health, Exercise and Sports Sciences at the University of New Mexico and an internationally recognised researcher in concussion management. Her work has focused on improving recovery pathways for individuals with concussion, particularly university students and performing artists—groups that have historically lacked evidence-based return-to-activity guidelines. During her doctoral studies at the University of Michigan Concussion Center, she developed one of the first structured Return-to-Learn protocols specifically designed for post-secondary students, helping universities better support students' safe return to academic participation following concussion. 01:22 – Journey into Athletic Training and Concussion Research  04:40 - What is a concussion? 6:45 - Difficulties in assessing and diagnosing concussion in collegiate/ university athletes 07:50 – Barriers & Difficulties in Assessing Students and Athletes for Concussion 12:10 - What’s the Return-to-Learn Process Look Like  21:20 – Concussion in Preforming Arts  24:50 – Concussion in Sport 29:40 – Return-to-Learn in Preforming Arts 33:20 – Favourite Moments in Sport/ Work 35:45 – Where to Find and Support Dr Memmini   Assistant Professor Allyssa Memmini  https://coehs.unm.edu/faculty-staff/profiles/memmini-allyssa.html   Google Scholar: https://scholar.google.com/citations?user=m1a6H_QAAAAJ&hl=en   Twitter: @first concussion Facebook: Headfirst: A concussion podcast Instagram: Headfirst_ Concussion   Email: headfirstconcussion@gmail.com

    The Buffalo Concussion Treadmill Test (BCTT) with Dr John Leddy

    Send us Fan Mail Dr. John J. Leddy is a primary care sports medicine physician with UBMD Orthopaedics & Sports Medicine and Professor of Clinical Orthopaedics at the University at Buffalo Jacobs School of Medicine and Biomedical Sciences. He serves as the Medical Director of the University at Buffalo Concussion Management Clinic, where he has played a leading role in advancing the clinical assessment and management of concussion. In collaboration with Dr. Barry Willer, Dr. Leddy co-developed the Buffalo Concussion Treadmill Test (BCTT), a validated exercise tolerance assessment that has become an internationally recognised tool for guiding safe, individualised return-to-activity protocols following concussion. His work has significantly influenced contemporary concussion rehabilitation by challenging the traditional recommendation of prolonged rest and supporting the use of carefully prescribed sub-symptom threshold aerobic exercise as an evidence-based treatment strategy. Dr. Leddy's contributions to sports medicine and concussion research have been recognised through numerous prestigious awards, including the American Medical Society for Sports Medicine's Best Overall Research Award and the 2022 Stockton Kimball Award for Outstanding Scientific Achievement and Service from the University at Buffalo. He has authored more than 200 peer-reviewed publications, with his research receiving over 20,000 citations, reflecting his substantial impact on the scientific understanding and clinical management of concussion worldwide. His body of work continues to inform international clinical guidelines and best-practice approaches to concussion diagnosis, rehabilitation, and return-to-sport decision-making.       01:30 - Journey into Medicine, Concussion research and Introduction to Buffalo Concussion Treadmill Test 11:20 – Shifting From ‘Cocooning to Exercise’ Induced Recovery  19:25 - Differences Between the Treadmill and Bike Test 25:30 – Completing Exertion Testing Without Heart Rate Monitor  30:25 – Full Return-to-Play  35:50 – ‘Myth Around Concussion/ Evolving Research’ 40:20 – Supporting and Where to Find Professor John Leddy Professor John Leddy  https://www.buffalo.edu/news/experts/john-leddy-faculty-expert-concussions.html https://www.researchgate.net/profile/John-Leddy-3     Twitter: @first concussion Facebook: Headfirst: A concussion podcast Instagram: Headfirst_ Concussion   Email: headfirstconcussion@gmail.com
