Q

subdural hematoma

A
  • blood btw dura matter and arachnoid layer

Q

intracerebral hematoma

A
  • blood deep in the brain tissue d/t injury form the frontal and temporal lobes
  • occurs when a blood vessel w/n the brain ruptures allowing blood to leak inside the brain
  • bone might become depressed and if there is an indentation we might need to do a craniotomy to get it back into shape
  • or craniotomy and then a cranioplasty to cover the area

  2. aural
  3. ictal
  4. postictal
78
Q

MS

A

plaque causes inflammation and starring in the CNS. IT causes damage to the myelin sheath and then eventually the nerve fiber.
- autoimmune, possibly d/t epstein barr virus

79
Q

What are the 3 mpathological processes that characterize MS?

A

chronic inflammation
demyelination
