after birth and applies to children and adults
can occur via traumatic causes such as injury or non traumatic causes such as disease, stroke, infection
Examples of non- traumatic brain injury
stroke- hemorrhagic/ischemic
brain tumor
hypoxia/anoxia
dementia
encephalitis
Examples of traumatic Brain injuries
diffuse:
-concussion
-diffuse axonial injury
-hypoxia anoxia
focal:
-subdural hematoma
-epidural hematoma
Do you routinely image patients to diagnose mTBI
NO
Define Concussion
traumatic brain injury induced by biomechanical forces. it may be caused by either a direct blow to the head, face, neck or indirect blow to the body that transmits forces to the head
Clinical signs and symptoms reflect a _______ disturbance rather than a structural injury.
functional

How do we classify a TBI?
Glasgow coma scale
Score of 8 or less on GCS
severe
Score of 9-12 on GCS
moderate
Score of 13-15 on GCS

falls -49%
MVA- 24%
other- 25%
-unintentionally being struck by or against an object
-unintentional self harm
-assault
concussion mechanism is _____ not structural.
physiological
injury occurs resulting in alteration of neuronal membrane
increase cellular demand for ATP
increase glucose demand
deregulation of blood flow in brain
metabolic demand may be greater than supply

No
Should an MRI be used to diagnose an MRI?
no
What is the timeframe for recovery after a concussion
24 hours to 7-10 days
What are some poor prognostic factors?
severity of acute and subacute symptoms
prior concussion
history of anxiety, depression or learning disabilities
cognitive deficits
females have greater risk than males
