Sleep after a knock to the head is often the first thing people stop noticing. You go to bed at the usual time, you wake up, and the day runs on the same tired rhythm as the one before. Over a week, though, those nights can tell a different story than memory does. A simple sleep note gives you something concrete to bring to an appointment in the St. Louis area, whether you are booking a visit this week or trying to make sense of how you have felt since the injury.
Why sleep belongs in the notes
Most people who see an examiner after a head injury are asked about symptoms in a rush. They are asked to recall when the headache started, what made it better, and how the last few days compared with the first few. Sleep is easy to forget in that moment. Yet changes in how long you sleep, how often you wake, and how rested you feel on waking are all things a person can observe without any equipment. They are plain facts about your own week, and they help an examiner understand the rest of the picture.
What to write each night
Keep a notebook or a note on your phone beside the bed. Each morning, before you check messages, write four things. First, the time you went to bed. Second, the rough time you fell asleep, if you can estimate it. Third, how many times you woke and whether you got up. Fourth, a short word for how you feel on waking, such as clear, heavy, foggy, or restless. Use the same words each day so the log is easy to compare. Skip the scoring and any app that promises a number. A few honest words are more useful than a figure nobody can explain.
Noticing the stretches that feel different
Some changes are quieter than others. You may find you are sleeping longer than usual and still waking tired. You may doze on the couch in the early evening and then lie awake at three in the morning. You may notice that light or noise wakes you more easily than it used to. Write these down as they happen. If you wake with the television on and cannot remember switching it off, that is worth a line. If a bedroom that felt fine last month now feels too loud, that is also worth a line.
Keeping the log from becoming a worry
A sleep log can start to feel like homework, and that is not its purpose. Pick a fixed moment, perhaps when you put the kettle on, and keep each entry short. If you miss a night, leave a blank and move on. The goal is a rough picture of the week, not a perfect record. Keep the log with your other notes about the days after the injury, so the pieces are easy to bring together when you sit down with an examiner.
What to bring and what to ask
When you arrive, bring the log and read it aloud if that helps. Note any changes that started after the injury and any that were already happening before it. Mention caffeine, screens late at night, and any new medicine you have taken for sleep or headache, without guessing at what those things mean. Ask the examiner which parts of your sleep pattern they want tracked over the next week, and whether they would like you to return with another log. A useful visit should leave you knowing what to watch and when to call again.
When a sleep change needs prompt attention
Some changes should not wait for a scheduled visit. If someone finds it hard to wake you, if sleep brings new confusion, if you vomit repeatedly, or if you notice weakness, slurred speech, or a headache that keeps getting worse, treat that as urgent and seek emergency care right away. The log is for ordinary observation between appointments. It is never a substitute for prompt examination when something feels seriously wrong.
A plain close
Sleep notes will not tell you what is happening inside your head, and they will not settle a question by themselves. What they do is give a busy person something steady to hold onto when the days blur together. Write the times, write the words, and let the examiner decide what the pattern means. This is general education, not a diagnosis, and it is meant to help you prepare for the conversation you are already planning.
