How does a concussion react?

Concussion usually occurs dizziness, headache, blurred vision, vomiting and other reactions.

1, dizziness

concussion, brain by external force impact, resulting in temporary changes in intracranial pressure, may stimulate meninges and intracranial blood vessels, and then cause dizziness.

2, headache

when the head is subjected to external force impact, brain tissue may be vibration and distortion, resulting in neuronal activity disorder, and then stimulate the pain sensitive structure in the brain, resulting in headache symptoms.

3, blurred vision concussion

, increased intracranial pressure may lead to transient brain optic nerve damage, or traumatic optic nerve damage, retinal concussion, macular edema and other conditions, will affect the normal function of the visual conduction pathway, resulting in blurred vision.

4, vomiting

concussion may lead to increased intracranial pressure, stimulation of central vomiting, resulting in vomiting.

If the symptoms are serious, should seek medical advice.
