neurological sequelae

I noticed that there were 3 searches on “what is neurological sequelae” today that led to this blog site.  I’m thinking you didn’t find the answer, so I thought I might go into this a bit.  “Neurological sequelae”, whoa, big phrase, huh?  Let’s break it down.  The secret to answering the question is to look up the word ‘sequelae’.  Wikipedia covers it pretty well (I know, the instructors say not to use Wikipedia, but this is not to use as a reference in a paper, so….):  http://en.wikipedia.org/wiki /Sequela.  It states, “A sequela, (pronounced /sɨˈkwiːlə/, plural sequelæ) is a pathological condition resulting from a disease, injury, or other trauma”.  Now you can understand that ‘sequelae’ could be neurologic, cardiologic, metobolic, etc, right?

Of course to answer the question, you must know what the original disease, injury or other trauma is.  For example, herniation would be one neurological sequela to increased ICP.  Increased ICP could be a neurological sequela to a subdural hematoma.  In other words, of a certain neurological problem, what could it progress into.    

In Case You Don’t Know:  Subdural hematoma – a hematoma (internal bleeding) between the dura (the inner most ‘covering’ layer around the brain) and the brain. ICP or Intracranial Pressure – pressure within the cranium or head caused by swelling of the brain or bleeding in the cranial cavity (this is not a good thing, because, once your fontanelle’s grow together as a baby, your head doesn’t really expand; it is a closed cavity).  Herniation of the brain – if you have swelling of the brain or bleeding that is taking up space in the head, the brain, being crowded, only has one place to go; down the brain stem.  This is known as the brain herniating (This can be partial or full.  Full is rarely, if ever, recoverable and is assessed as a blown pupil):

If you have a question about specific neurological sequela, let me know what it is.  I’ll see what I can figure out for you.

I love neurology, so give me all the questions you have.
