Flashcards in Neurological Infections - Encephalitis Deck (16):
1

What is parenchyma?

Functional tissue in any organ

2

Why is encephalitis usually viral?

Because the parenchyma is made up of tissues and cells and viruses use the cells to replicate their data. And bacteria does not.

3

What are the two most common viruses that cause encephalitis?

HS1 and arbovirus

4

What is the patho of encephalitis?

Localized necrosis of neurons and hemorrhage leads to generalized necrosis of neurons and hemorrhage which leads to edema in the brain tissue itself

5

Is the progression of encephalitis predictable?

No

6

What are manifestations of encephalitis?

Neurological disturbances (lethargy)
Fever
Headache
Nausea and vomiting
Nuchal rigidity

7

What are complications of encephalitis?

Seizures

8

In encephalitis, what determines the neurological disturbances that may appear?

The area of the brain that is targeted

9

Which virus that causes encephalitis is the most aggressive virus?

HS1 virus

10

Which virus is less severe that causes encephalitis?

Arbovirus

11

What is the treatment for encephalitis If it is cause by HS1 virus?

Antiviral drugs (acyclovir) must be given IV

12

What is the treatment if encephalitis is caused by arbovirus?

Symptomatic management and must monitor for complications

13

How long does it usually take for encephalitis to subside if caused by a less aggressive virus?

About 2 weeks

14

What are possible long term severe neurological impairments that can arise from encephalitis?

Dementia and epilepsy

15

What is the mortality rate of encephalitis?

About 30%

16

What is encephalitis?

Inflammation of the parenchyma (brain and spinal cord)
