1. What is a concussion?
A concussion is a mild traumatic brain injury caused by a bump, blow, or jolt to the head or body that shakes the brain inside the skull. It can temporarily affect brain function.
2. What causes a concussion?
Concussions are usually caused by falls, sports injuries, car accidents, or any trauma to the head. Even a minor impact can cause a concussion if the brain moves quickly inside the skull.
3. What are the symptoms of a concussion?
Symptoms can appear immediately or within hours and may include headache, dizziness, nausea, vomiting, blurred vision, sensitivity to light or noise, confusion, memory problems, balance issues, and sometimes loss of consciousness.
4. How is a concussion diagnosed?
Diagnosis is made through a medical history, symptom assessment, and neurological examination. Imaging such as CT or MRI may be used if a more serious brain injury is suspected.
5. How long does it take to recover from a concussion?
Recovery usually takes a few days to a few weeks, depending on the severity of the concussion and individual factors. Some people may experience lingering symptoms for longer (post-concussion syndrome).
6. How is a concussion treated?
Treatment primarily involves rest and gradual return to normal activity. Avoiding physical and cognitive strain in the first few days is important. Pain can be managed with simple analgesics like paracetamol. Monitoring for worsening symptoms is crucial.
7. Can repeated concussions be dangerous?
Yes. Multiple concussions over time can lead to long-term brain problems, including cognitive impairment, mood changes, and neurological issues. Protective measures are important, especially in contact sports.
8. When should I see a doctor after a head injury?
See a doctor immediately if there is loss of consciousness, worsening headache, repeated vomiting, confusion, slurred speech, weakness or numbness, vision changes, or seizures, as these may indicate a serious brain injury.
9. Can I prevent a concussion?
Prevention includes using protective gear like helmets, following safety rules in sports and activities, using seatbelts in vehicles, and minimizing fall risks at home or work.
10. What activities should be avoided after a concussion?
After a concussion, it is important to avoid strenuous physical activity, contact sports, heavy lifting, and activities requiring intense concentration until cleared by a healthcare professional. Gradual return to normal activities should be guided by symptom resolution.
