3.1 Meningitis, Encephalitis Flashcards
meningitis
inflammation of the meninges
s/s meningitis
- stiff neck
- achy
- feverish
- malaise
- diffuse headache
Why would someone with meningitis have a headache?
everything is inflamed
causes of meningitis
- bacteria
- virus
- fungal
worst type of meningitis
bacterial
viral meningitis
- typically caused by enterovirus
- usu virus runs its course and they get better
- don’t see too many with viral infections in the hospital
Where could fungal meningitis come from?
- moist environments
- dirt
- animal feces, esp bird droppings
What is a major issue with treating meningitis?
getting through the blood brain barrier
long term problems after meningitis?
scarring of the meninges
- get blockages (intermittent or permanent) preventing flow of CSF
- pt may need a shunt if it’s bad enough
What do blockages preventing the flow of CSF cause?
- pressure on the brain
- neuro changes, dizziness, vomiting, etc.
VP shunt
ventriculoperitineal
What do you need to pay attn to if a pt has a VP shunt?
headaches and other changes they had before (can become clogged or kinked) due to CSF buildup
purpose of spinal tap
drain some fluid to see what it
ICP
intracranial pressure
causes of encephalitis
- virus
- bacterial
- fungal
most common cause of encephalitis
viral
Why is it better to have meningitis over encephalitis?
typically doesn’t cause as many neurological issues
What is encephalitis?
inflammatory response inside the brain
Why is encephalitis such a bad thing?
nowhere for the brain to go within the cranial vault
s/s of encephalitis
- headaches
- bad sensitivity to light
- fever, achy, malaise
- more neuro symptoms because the entire brain is having issues
- quick decline in status
- anything the brain controls could cause s/s
What things may be affected when an encephalitis pt begins to decline quickly?
- confusion
- seizures
- nausea/vomiting
- vision
- hearing
- motor control
- sensory
*go to stupor/coma quickly
scarring and encephalitis
- same problems as with meningitis
- now, the ventricles can scar and more widespread
What are encephalitis pts treated with?
tons of steroids that can make it through the BBB
What happens if swelling gets really bad, brain swells into the foramen magnum?
uncal herniation
*worst case scenario
