Causes: direct/indirect force to head, face, neck, etc. **it is not always loss of consciousness it may/may not. Acute signs/symptoms: headache, confusion, imbalance, visual problems, loss of memory, behaviour change. Use of the memory test -seeing how many words or numbers can be remembered. Use of reverse numbering can be very helpful for evaluation of the concussion -other test like today"s date is not good. Simple concussion: no loss of consciousness -it is brief symptoms around 10min to 10days. Symptoms recover within 30mins & full recovery is commonly 7-10days. Complex concussion: it is traumatic concussion after simple concussion as well as repeated concussion. They have loss of memory around more than 30min for more than 24hours. It is linked with loss of some motor task and other sensory type. Ongoing concussion evaluation: requires multiple diagnosis test for brain imaging and the test of the concussion.
