Post-Concussion Red Flags for Calabasas Patients
First things first: you are not alone, and recovery is absolutely possible. Calabasas is a community that loves movement trail runs, school sports, weekend pickleball so concussions happen. What matters now is smart monitoring. In the early days after a head injury, certain symptoms deserve immediate attention. In this guide, I’ll explain those Post-Concussion Red Flags in calm, clear language, show you what’s normal vs. not, and give you practical steps you can follow today. My goal is simple: keep you safe, encouraged, and moving steadily toward full recovery.
What Counts as a Concussion and Why Red Flags Matter

A concussion is a transient disturbance in brain function after a blow to the head or body that jars the brain. Most concussions improve with time and pacing. Yet a small number can evolve into more serious conditions this is why knowing the Post-Concussion Red Flags is so important. Think of red flags as your “do-not-ignore” signals: when they show up, we change the plan quickly and safely.
Traumatic Brain Injury Recovery — Red flags deserve swift triage and, once cleared, a measured plan. We turn the “scare” into structure: sleep and screen rules, hydration, symptom pacing, and when to escalate. Expect a one-page action sheet so the whole family knows what to watch for over the next 72 hours.
The 24/72/10 Rule: A Friendly Timeline to Anchor Your Decisions
When patients ask how to watch for Post-Concussion Red Flags, I offer a simple timeline:
-
First 24 hours: The brain is most sensitive. Rest, hydrate, keep stimulation low. If severe symptoms appear (see red-flag list below), act immediately.
-
24–72 hours: Gradual improvement should begin. Light activity that doesn’t worsen symptoms is okay. Red flags here still require prompt medical attention.
-
3–10 days: You should see a clear trend toward better. If symptoms plateau or intensify, especially if new Post-Concussion Red Flags develop, it’s time for a re-evaluation.
If you’re unsure at any point, assume your brain is asking for help and reach out.
The Core Post-Concussion Red Flags (Act Now)

These are the classic Post-Concussion Red Flags that warrant urgent evaluation today, not tomorrow. If you see any of the following, seek emergency care right away:
-
Worsening, severe headache that is not relieved with rest and becomes more intense over hours.
-
Repeated vomiting (more than once).
-
Increasing confusion, agitation, or unusual behavior (e.g., not recognizing familiar people or places).
-
Loss of consciousness at the time of injury or any new episodes of fainting afterward.
-
Seizure-like activity (jerking movements, unresponsiveness).
-
Weakness, numbness, or clumsiness on one side of the body; difficulty walking.
-
Slurred speech, new trouble finding words, or profound drowsiness that’s hard to wake from.
-
Unequal or abnormally large pupils, or double vision that appears or worsens.
-
Neck pain with concerning stiffness after trauma, especially if paired with neurologic symptoms.
-
A sudden, dramatic change in symptoms after a period of seeming okay.
These are not “wait and see” signs. They are true Post-Concussion Red Flags.
Yellow Flags: Concerning but Often Manageable with Prompt Guidance
Some symptoms aren’t full-on emergencies, but they should prompt same-day contact with a clinician especially if they escalate:
-
Headaches that wax and wane but trend more intense after day two.
-
Vertigo or severe dizziness that makes it hard to stand or turn your head.
-
Photophobia (light sensitivity) or phonophobia (sound sensitivity) that moves from mild to moderate despite rest.
-
Cognitive fog that worsens with simple tasks paying bills, reading a page, following a recipe.
-
Sleep disruption (can’t fall asleep, can’t stay asleep) that fuels daytime exhaustion.
-
Mood shifts irritability, anxiety, or low mood that feel unlike you.
-
New sensitivity to motion in the car (passenger or driver).
If any of these yellow-flag symptoms cross your personal comfort threshold, treat them like Post-Concussion Red Flags and get evaluated.
Concussion Sleep Routine Blueprint — After urgent concerns are addressed, this blueprint helps you stabilize nights—arguably the strongest lever for next-day symptoms. It outlines exact wind-down steps and timing so your brain can repair consistently.
Special Situations: Children, Older Adults, and “Hidden Risk” Groups

Some patients are more vulnerable to complications and should be watched extra closely for Post-Concussion Red Flags:
-
Children & teens: They may not have the language to describe worsening symptoms. Watch for inconsolable crying, refusal to eat, unusual sleep, loss of interest in favorite activities, or a teacher’s note about decline in attention.
-
Older adults: Subtle changes slower walking, “just a little more tired” can mask hazard. A minor bump can still lead to significant issues.
-
People on blood-thinning medications: Even small head impacts can be higher risk. Any red flag warrants immediate assessment.
What’s “Normal Enough” vs. Not: Context for Common Symptoms
After a concussion, it’s typical to have a mild version of the following for a few days:
-
Headache that responds to hydration, quiet, and limited screen time.
-
Light dizziness when getting up quickly that improves when you sit back down.
-
Some concentration trouble late in the day that resets after a good night’s sleep.
These are not automatic Post-Concussion Red Flags unless the severity or frequency increases, or they stop improving after day three.
A Simple Home Monitoring Plan (So You Don’t Have to Guess)
Use this quick daily checklist for the first week:
Morning (rate 0–10):
-
Headache: __
-
Dizziness: __
-
Light/Sound sensitivity: __
-
Cognitive clarity (“I can focus”): __
-
Mood/Anxiety: __
-
Fatigue: __
Evening notes:
-
Activities attempted (walk, reading, work emails).
-
Did symptoms spike (Y/N)? By how much (0–3)?
-
Any Post-Concussion Red Flags? (If yes, what and when?)
What you’re looking for is trend. A gentle downward slope in symptom numbers is reassuring. A jagged line that climbs especially with one of the Post-Concussion Red Flags means call your clinician.
Activity Pacing: How to Progress Without Provoking Red Flags

Rule of 6/10: During early recovery, keep activities at a symptom intensity of six out of ten or less, and no spikes that linger more than an hour afterward. If a walk, a Zoom call, or homework pushes you past that, dial it back. This approach actively reduces the risk of triggering Post-Concussion Red Flags.
Recovery Rhythm for Calabasas life:
-
Morning: Short walk in low light (hat + sunglasses if needed), water, high-protein breakfast.
-
Midday: Work or study in 25-minute blocks, 5-minute eye/neck breaks.
-
Afternoon: Light vestibular drills if prescribed, gentle breathing (4–6 breaths/min), hydration.
-
Evening: Dim lights an hour before bed, devices on night mode, calming routine.
Sleep: Your Brain’s Repair Window
Good sleep is a natural stabilizer. Tips:
-
Consistent bedtime and wake time even weekends.
-
Cut caffeine after noon; keep screens dim at night.
-
If daytime naps are necessary, keep them under 30 minutes.
Sleep that worsens or becomes fragmented over several days can be a precursor to Post-Concussion Red Flags especially if paired with heavier headaches or irritability.
Hydration, Nutrition, and the “Inflammation Curve”
Dehydration and blood-sugar dips amplify concussion symptoms. Simple wins:
-
Aim for steady water intake through the day (carry a bottle; sip, don’t chug).
-
Pair carbohydrates with protein and fiber (apple + nut butter; yogurt + berries).
-
Consider omega-3–rich foods (salmon, chia, walnuts) and colorful produce to support the brain’s natural recovery processes.
A diet that steadies energy often dampens symptoms that might otherwise drift toward Post-Concussion Red Flags.
Driving, Screens, and Exercise Three Common Triggers
-
Driving: Delay until you can scan mirrors, process visual motion, and react quickly without symptom spikes. If driving reliably provokes headache, nausea, or confusion, that’s functionally a Post-Concussion Red Flag and you should pause and seek guidance.
-
Screens: Use night-mode or blue-light filters; follow 20-5 breaks (20 minutes on, 5 off) in the first week.
-
Exercise: Start with walking; progress to light aerobic activity when symptom-stable. Avoid contact sports or high-risk movements until cleared.
What to Bring to a Neurology Visit After a Concussion
Arriving prepared helps us help you:
-
Your symptom diary with any Post-Concussion Red Flags noted by time and trigger.
-
A list of activities that make things better or worse.
-
A brief timeline of the injury and the first 48 hours after it.
-
Questions you want answered (top three is perfect).
Together, we translate your real-life data into a targeted plan.
Myths That Keep People Stuck (Let’s Clear Them Up)
-
“If I rest completely for weeks, I’ll heal faster.”
Not exactly. Gentle, graded activity (below symptom threshold) generally supports recovery and reduces the chance of Post-Concussion Red Flags appearing later when you suddenly ramp up. -
“If the first scan was normal, nothing serious can happen.”
Most concussions don’t show on standard imaging. That’s why we follow function over time and watch carefully for Post-Concussion Red Flags. -
“Kids bounce back quicker, so I don’t need to be strict.”
Children recover well, but they need structured pacing and consistent monitoring just as much as adults.
Emotional Health Is Brain Health
Irritability, anxiety, or low mood can appear after concussion. That does not mean you’re failing; it means your stress system is working overtime. Simple practices two minutes of slow breathing, sunlight, a short walk with a friend can shift your nervous system toward recovery. If mood changes are severe or worsening, treat them as Post-Concussion Red Flags and get timely support.
When to Seek Same-Day Care vs. Emergency Care
-
Emergency care now: any item from the “Core” Post-Concussion Red Flags list.
-
Same-day neurology or primary care: yellow flags that are escalating, no meaningful improvement after 72 hours, or a “something isn’t right” intuition you trust.
Your safety net is stronger than you think. Reaching out early changes outcomes.

Summary
Knowing the Post-Concussion Red Flags gives you calm control in a stressful moment. In the first 24–72 hours, prioritize rest, hydration, and gentle pacing while watching for severe headache, repeated vomiting, worsening confusion, seizures, weakness, slurred speech, troubling vision changes, or profound drowsiness. Use a simple daily checklist, progress activities below your symptom threshold, and protect sleep. Children, older adults, and people on blood-thinning medications deserve extra vigilance. When in doubt, ask for help early small course corrections now prevent big problems later.
Frequently Asked Questions
1) How long should I watch for Post-Concussion Red Flags?
Keep close watch for at least the first 72 hours, then continue daily check-ins for a week. Any sudden worsening whenever it occurs counts as a Post-Concussion Red Flag.
2) Is it safe to sleep the first night after a concussion?
Yes if no Post-Concussion Red Flags are present. Arrange gentle check-ins (e.g., a family member observes normal breathing and easy arousability) during the first night. If waking is difficult or confusion appears, seek care.
3) When can I return to school or work?
When you can complete short blocks of cognitive activity (20–30 minutes) without symptom spikes that last more than an hour. If attempting this triggers Post-Concussion Red Flags, pause and contact your clinician.
4) Can I exercise?
Light, sub-symptom walking is encouraged within 24–48 hours if no Post-Concussion Red Flags are present. Progress gradually with professional guidance.
5) What if my child seems “almost normal” but gets cranky and tired at practice?
That pattern suggests incomplete recovery. Treat persistent irritability and fatigue with exertion as potential Post-Concussion Red Flags for youth sports and scale activity down until cleared.
6) Do screens make concussions worse?
They can in the early phase. Use night mode, frequent breaks, and larger fonts. If screen use consistently triggers Post-Concussion Red Flags (like severe headache or dizziness), limit and discuss alternatives with your clinician.
7) My headache is improving, but I suddenly have double vision.
New double vision is a true Post-Concussion Red Flag seek urgent evaluation.
8) If my initial ER visit was “normal,” can I ignore new symptoms later?
No. New or worsening symptoms still qualify as Post-Concussion Red Flags and require prompt reassessment, even after a normal early evaluation.
You’ve got this. With a clear plan, compassionate support, and attention to the Post-Concussion Red Flags, recovery isn’t just possible it’s likely. Keep going, and let us help you make each day a little steadier than the last.
