Most people remember the big hit. Fewer remember the small ones: the bump on a cabinet door, a fall on wet steps, a collision during a rec-league game, a fender-bender at a red light. Your body keeps track of these whether or not your memory does. Writing them down before an appointment is one of the simplest things you can do.
This week, The Guardian reported on a new study published Wednesday in JAMA Network Open. The research estimates that about 75% of former NFL players who died over a 15-year period had evidence of chronic traumatic encephalopathy, a brain disease associated with repeated head impacts. The study looked at players after they died. It cannot tell a living reader whether they have the condition, and no news item can do that. What it does is keep repeated head trauma in the public conversation, which is a good reason to start a personal record.
What to Write Down
Start a simple list with one line per event. For each one, note the approximate year, what happened, and whether you were dazed, saw stars, lost consciousness, or had a headache, nausea, or trouble concentrating afterward. Approximate answers are fine. "Around 2012, during a soccer season" is far more useful than a blank line.
Look beyond sports. Car accidents, work incidents, falls at home, ladder slips, and childhood playground injuries all count. So do organized sports at every level, including the ones you played for only a season or two. Many people leave out the injuries that happened long ago because they never saw a doctor for them, and those are often the entries an examiner most wants to hear about.
Why the Pattern Matters
A single event and several events over many years tell different stories. An examiner will usually ask how many impacts you can recall, how recent the most serious one was, and whether symptoms fully cleared each time. Those questions are easier to answer from a page than from memory in a waiting room. A written timeline also shows gaps, such as a stretch of years with no reported incidents, which can be just as informative.
How to Bring It to the Exam
Bring the list on paper or on your phone. Add your current medicines, including over-the-counter pain relievers and any blood thinners, since these change how a head injury is handled. Note any changes you have noticed in sleep, mood, memory, or focus, along with the month each one began, even if they seem unrelated to an old knock.
Keep the list with your other visit notes so you can update it later. A new event, a change in symptoms, or a question you forgot to ask can all go on the same page.
Do not wait for an appointment if a head injury is followed by confusion, repeated vomiting, a seizure, unequal pupils, a worsening headache, or weakness on one side of the body. Those signs call for emergency care right away.
Writing down your history does not mean you need a particular test or a particular answer. It gives your examiner a timeline to work from and gives you a document to revisit. If you have had several head impacts over the years and you are noticing changes now, the best time to share that history is before you feel pressed to explain it on the spot.
