signs of concussion?

Accepted Answer

Dizziness: Dizziness especially with rapid head movements; confusion, loss of consciousness, strange sensation in areas of the body; garbled speech; weakness in an extremity; these depend upon the part of the brain affected; so not all of them may show in a particular case.  I struck the back of my head and had black vision for several seconds followed by vertigo for about 6 weeks without loss of consciousness.

Question 3

what causes a concussion?

Accepted Answer

Concussion: Is a bruise of brain tissue caused by the brain's bouncing against the bony skull; loss of consciousness may result as may significant tissue damage, brain swelling, seizures, projectile vomiting. Head injuries should be followed up by doc to help determine severity & whether imaging studies are necessary.

Question 4

what's a double concussion?

Accepted Answer

Very dangerous: There's a syndrome called "second impact syndrome" which can occur as someone has a second concussion while recovering from their first concussion.  The resultant injury to the brain can cause malignant cerebral edema (swelling) and this can be fatal- mortality is 50-100%.

Question 5

can you be concussion prone?

Accepted Answer

Yes: I don't know about "concussion prone", but there is evidence that shows that athletes who sustain a concussion are more likely to have another concussion. The effect of repetitive concussions can be very serious.

what can cause a concussion?

Accepted Answer

Impact to head: Concussion is due to the brain absorbing force in either a direct or tangential force that causes the brain to "slosh" around inside the skull. This can cause neurological deficits that are usually temporary. Repeated concussions can lead to permanent brain damage, especially if they occur repeatedly before the effects of the prior concussion has resolved. Rarely in this situation death can occur.

Accepted Answer

NO : A concussion is a mild brain injury from trauma.  You will not die from a concussion but may suffer from a "post-concussion syndrome" . This can include headaches, nausea, irritability, poor focus, poor hand-eye-coordination, etc.   Mos patients who die from brain injury suffer from moderate to severe tbi (traumatic brain injury). Consult your md for full details.

Question 10

how many concussions is too many?

Accepted Answer

Depends on severity: Ideally, we would prefer that patients don't have any concussions. However, these do happen. The concern with multiple concussions is their cumulative effect. If the concussions occur within a short period of time serious brain injury can occur. The entity of "dementia pugilistica" occurs in boxers who suffer many concussions in a short period of time.
