0:00diseases and disorders of the nervous
0:02system can be quite complicated they
0:05generally start within the brain and the
0:07spinal cord
0:08and so here in this slide we have
0:10different types of paralysis so you have
0:13paraplegia
0:15quadriplegia
0:17hemiplegia and monoclegia and what you
0:21can see here in the picture is the
0:23different areas that are affected so
0:26paraplegia paralysis of the legs
0:30quadriplegia paralysis of the arms and
0:33the legs
0:34Hemi is going to be half of the body and
0:39mono affects just one limb
0:42so four different types of paralysis
0:45here all caused by spinal cord injuries
0:48you have neuralgia algaea means pain
0:52neural is nerve so neuralgia would be
0:55nerve pain
0:56we also have what's called ALS or Lou
1:00Gehrig's disease
1:02and with Lou Gehrig's disease you can
1:04see here with your healthy motor neuron
1:07compared to one that has been affected
1:10with ALS remember in our healthy neurons
1:13they have the ability to communicate
1:15with others uh sell to sell they create
1:18movement they create sensation and when
1:21that is affected which you can see here
1:23in the damaged motor neuron there won't
1:26be the ability to communicate throughout
1:28the dendrites because they're they're
1:30affected uh and so this is a fatal
1:33disorder
1:34it is degenerative it can occur over a
1:37long period of time it varies Patient to
1:40Patient but it starts with having
1:42healthy neurons that then become
1:44affected and they lose the ability to
1:46communicate with others and that can
1:49cause what you see here in the photo uh
1:52paralysis and then eventually leads to
1:54unfortunately can lead to death
1:56meningitis uh also known as kissing
1:59disease uh very common within the youth
2:03the teenagers it's an inflammation or
2:06infection of the lining of the brain in
2:08the spinal cord
2:09Parkinson's disease something that we're
2:11still learning a lot about it is
2:14Progressive degenerative so it can take
2:17a period of time to affect the system
2:19but it does eventually affect the motor
2:22system motor system
2:24and what it does is it causes
2:27uncontrollable Tremors or shakes
2:30Tia transient ischemic attack otherwise
2:34known as a stroke
2:37starts with what's called a mini stroke
2:39and that mini stroke we refer to as a
2:42warning sign typically when someone has
2:45the signs or symptoms of a mini stroke
2:47it's letting us know what may be to come
2:50and so it's important when someone does
2:53experience these types of um uh
2:56disorders that they seek treatment
2:58immediately we want to be able to get
3:00ahead of problems that could arise in
3:03the future
3:04Bell's Palsy is what you see in the
3:07photograph here
3:08and Bell's Palsy uh also part of the
3:11nervous system can be caused by various
3:14reasons uh it's also linked to pregnancy
3:17stress
3:19causes weak or paralyzed facial muscles
3:22and it's temporary
3:24so as long as that stress is a factor we
3:28typically see the bell's palsy occur
3:30once that stress is reduced so is the
3:33paralysis within the face
3:37epilepsy these are seizures the body has
3:41its own electrical conductivity that's
3:43happening within the cardiovascular
3:45system uh also there's electrical
3:48conductivity happening within the brain
3:50and so uh seizures result from burst of
3:54electrical signals in the brain it's
3:56just a whole mess of signals that are
3:58happening at once and the Brain can't
4:01take in what's happening and so uh it it
4:04seizes is what happens
4:08a stroke last term there otherwise known
4:11as CVA a blood vessel in the brain is
4:15either blocked by a clot or burst
4:18and brain damage can occur due to the
4:22lack of blood flow Strokes do restrict
4:25the amount of blood that is flowing
4:28through to the brain and so uh if this
4:31is not treated very very quickly this
4:33could be extremely detrimental
4:37uh and CVA cerebrovascular accident
4:41headaches uh part of diseases and
4:44disorders associated with the nervous
4:46system different types of headaches we
4:48see patients experience we have
4:51migraines which is the most common and
4:54migraines are classified by their
4:57symptoms their symptoms are different
4:58from your typical headache so with
5:00migraines we see nausea vomiting light
5:03sensitivity
5:05whereas cluster headaches are just that
5:07their severe form of migraines that
5:10occurs in groups
5:12so one after the other and then tension
5:15tension can be chronic over a period of
5:18time or episodic dealing with stress
5:21that's happening right now in this
5:22moment can cause a tension headache very
5:26last disorder there is called Julian
5:27Barr syndrome and this is an autoimmune
5:30disease that attacks the peripheral
5:31nervous system over time and when you
5:34hear the term autoimmune that means that
5:36the body is fighting its own healthy
5:39cells
