Let’s continue taking a
look at neuropathology.
Here, the overall theme
would be CNS infections.
With CNS infections, these are
topics that we’ll take a look at.
For the most part, it
comes under microbiology.
And what is the
that you want to take with CNS
infections will be the overall theme.
We’ll walk through quickly
some bacterial, viral, fungal;
to you the Lyme disease;
parasitic and, ultimately,
Prion itself, as you
know, in microbiology,
there’s a lot of research
in terms of how it behaves.
It’s quite interesting because it
is considered to be contagious,
it’s difficult to understands the
behavior of this prion disease
as you’ve heard of mad cow
disease for an example.
The classifications we’ll take
a look at under meningitis is,
as I said, the overall theme for
this is going to be CNS infections.
But under meningitis,
apart from the infections agents maybe
bacterial, viral or fungal, whatnot,
there will be other causes of meningitis
that is not so much infectious,
just keep that in mind as we walk
through more of these issues.
Now, what’s the difference between
meningitis and encephalitis?
Well, from neuroanatomy,
remember that the meninges,
well, if they undergo infectious changes,
that it undergoes an inflammatory process.
And then of course, the
lumbar puncture and
the evaluation of your cerebrospinal
fluid becomes incredibly important.
But what’s underneath the meninges,
what’s underneath that pia matter?
Oh yeah, you have the
What if the brain parenchyma
then becomes injured
and undergoes an
Well, at this point, you
call this encephalitis.
And we’ll take a look at various
causes of encephalitides.
Myelitis, referring to your spinal cord.
And then, quickly walk you through
some important abscess information.
