Did I Suffer a Concussion After a Bike Fall? Symptoms

The bike slipped, and I first hit my waist, followed by my head?

I fell off my bike today after slipping, hitting my lower back first and then my head.
After hitting my head, I felt a bit dizzy, but I was able to get up and stand without any issues.
I didn't experience any vomiting or other symptoms of a concussion, and I walked steadily.
So, doctor, do I have a concussion?

Dr. Jiang Junyi reply Neurology

Hello, based on your description, head trauma must be assessed through observation.
If the patient is conscious and only has scalp lacerations, mild headache, and dizziness, observation is sufficient and a CT scan is not necessary.
However, if there is post-traumatic amnesia, loss of consciousness, vomiting more than twice, severe headache, post-traumatic seizures, significant subcutaneous hematoma, multiple traumas, penetrating injuries, skull fractures, falls from a height greater than one meter, major accidents, age over 65, a history of coagulopathy, or long-term use of antiplatelet medications, a CT scan should be performed.
Approximately 3-5% of patients with mild head trauma may experience deterioration, which can even pose a life threat.
Therefore, if the CT scan results are abnormal, hospitalization for observation and treatment is warranted.
If the patient's Glasgow Coma Scale score is 15 within 48 hours of the injury, and they are conscious with no other symptoms or focal neurological signs, the chance of deterioration is extremely low.
It is recommended that you consult a neurosurgeon.
Wishing you good health and peace.

More Info

After a bike fall, it’s important to assess whether you may have suffered a concussion, even if you feel fine immediately afterward. A concussion is a type of traumatic brain injury (TBI) that can occur when the head experiences a sudden impact or jolt, causing the brain to move within the skull. Symptoms of a concussion can vary widely and may not appear immediately.
In your case, you mentioned that you experienced a brief moment of dizziness after hitting your head but were able to get up and walk without any issues. This is a positive sign, as many people who suffer concussions may experience more severe symptoms such as confusion, loss of consciousness, or persistent dizziness. However, it’s crucial to understand that not all concussions present with obvious symptoms right away.
Common symptoms of a concussion can include:
- Headache
- Dizziness or balance problems
- Nausea or vomiting
- Sensitivity to light or noise
- Difficulty concentrating or remembering
- Fatigue or drowsiness
- Mood changes
Since you did not experience vomiting or significant balance issues after the fall, it might suggest that you did not suffer a concussion. However, it is essential to monitor yourself for any delayed symptoms. Concussions can sometimes manifest hours or even days after the initial injury.
Given your situation, here are some recommendations:
1. Monitor Symptoms: Keep an eye on how you feel over the next few days. If you start to experience any symptoms such as persistent headaches, confusion, or difficulty concentrating, it’s important to seek medical attention.

2. Rest: Allow your brain to recover. This means getting plenty of sleep and avoiding activities that require intense concentration or physical exertion until you are sure you are symptom-free.

3. Avoid Alcohol and Drugs: These substances can impair your cognitive function and may mask symptoms that could indicate a concussion.

4. Consult a Healthcare Professional: If you have any concerns or if symptoms develop, it’s wise to consult a healthcare provider. They may recommend a neurological evaluation or imaging studies like a CT scan or MRI if they suspect a more serious injury.

5. Follow Up: If you have any lingering symptoms or if you feel uncertain about your condition, follow up with a healthcare professional. They can provide a thorough assessment and determine if any further evaluation or treatment is necessary.

In conclusion, while it sounds like you may not have suffered a concussion based on your immediate recovery, it’s crucial to remain vigilant for any delayed symptoms. If you have any doubts or if your condition changes, don’t hesitate to seek medical advice. Your health and safety should always come first.
