Q

ischemic vs hemorrhagic stroke
_________ Patho:

  1. large area effected - bleeding into the brain tissue can affect a large area, leading to significant damage
  2. increase in ICP - The accumulation of blood increases ICP and causes inflammation, compressing surrounding brain structures.
  3. herniation - This can result in life-threatening herniation, where brain tissue is shifted and compressed against the skull.
  4. death - Unrelieved herniation, particularly of the brainstem, can cause respiratory arrest and death.

_________ Patho
1. decreased blood supply (from occlusion)
2. oxygen deprivation
3. neuro deficits w/in 1 min
4. continued loss of supply leads to irreversible damage

hemorrhagic stroke Patho
1. large area effected - bleeding into the brain tissue can affect a large area, leading to significant damage
2. increase in ICP - The accumulation of blood increases ICP and causes inflammation, compressing surrounding brain structures.
3. herniation - This can result in life-threatening herniation, where brain tissue is shifted and compressed against the skull.
4. death - Unrelieved herniation, particularly of the brainstem, can cause respiratory arrest and death.

Q

Cerebrovascular disease
TIA vs stroke
1. Transient ischemia attack
2. Transient episode of neuro dysfunction w/out acute infarction
3. neurological deficits lasting >24 hours
4. acute focal cerebral insufficiency lasts <24 hours, usually <1 hour
