So when it comes to conditions that affect the brain and its functioning, there is a lot of information to memorize.
00:12
So it can be helpful just to run through a few at a time and see if you can identify each one correctly.
00:20
So here we're going to be trying to find out which of these disorders is characterized by a progressive loss of memory and emotional and intellectual functioning.
00:31
So the two key things we're looking at is, is it progressive and does affect these three categories we listed of memory, emotion, and intelligence? first, we have meningitis.
00:46
This is an infectious disease causing inflammation of the meninges for the layers surrounding the brain, and it causes an accumulation of cerebrospinal fluid that exerts additional pressure on the brain and can cause brain damage.
01:02
So right off the bat, we see that this is an infectious disease, so probably not progressive, not what we're looking for.
01:10
And while brain damage can include memory, emotion, and intelligence, it can also span a wide range of things.
01:18
That's just kind of a catch -all term for damaging the brain in some way.
01:22
We're not really sure what way.
01:25
The next we have parkinson disease.
01:27
This is a neurodegenerative disease.
01:29
It is progressive.
01:31
So we've ticked off that box.
01:32
However, it targets dopaminergic neurons, otherwise known as neurons that produce dopamine.
01:40
And the destruction of these neurons results in impaired movement.
01:44
This is a very serious disease.
01:46
Impaired movement can eventually be fatal if it leads to paralysis of the respiratory tract.
01:53
But this is not hitting the three categories of memory, emotion, and intelligence that we're looking for...
