6.77 -> - Hello, I'm Valerie Parker
8.31 -> and I'm the inpatient
speech language pathologist
10.97 -> here at Vibra Rehab
Hospital in Amarillo, Texas.
14.87 -> I'm here today to talk to you a little bit
17.06 -> about brain injury and,
in particular, strokes.
20.27 -> Strokes are also known as
21.76 -> cerebrovascular accidents or CVAs.
24.75 -> And these terms are used
fairly interchangeably.
28.83 -> There are four main areas of the brain
31.3 -> that can be affected from a stroke.
33.67 -> These include the left hemisphere,
35.54 -> right hemisphere,
Cerebellum, and Brainstem.
39.3 -> So the effects of a
stroke depend on the size
42.76 -> and location of the stroke
45.94 -> and kind of the amount of brain tissue
48.96 -> that was affected as a
result of the stroke.
52.06 -> So I'm gonna talk about, a little bit
54.04 -> about the difference
between left hemisphere CVAs
57.2 -> and right hemisphere CVAs,
59.03 -> as there's some common characteristics
61.01 -> that are affected as a
result of the stroke.
64.92 -> So in general, a left hemisphere
67.19 -> controls the right side of our body.
69.83 -> So following a left hemisphere CVA,
72.84 -> patients will often have paralysis
75.05 -> or weakness on the right
side of their body.
78.21 -> The speech and language centers are housed
80.36 -> in the left hemisphere of our brain,
82.36 -> so patients with a left CVA
84.74 -> often have difficulty
with producing speech
88.49 -> or understanding language,
90.47 -> known as aphasia.
92.13 -> They can have difficulty
with reading and writing,
95.71 -> difficulty with math and problem solving,
99.31 -> time management, money management,
101.78 -> kind of the logical parts of our thinking
105.02 -> and reasoning processes.
107.55 -> They can often have
difficulty with swallowing
110.87 -> and can have some right
sided facial weakness,
114.14 -> which can result also in difficulty
116.21 -> chewing and swallowing their food.
118.33 -> So these are all kind of
common characteristics
120.98 -> of a left hemisphere stroke.
123.8 -> So conversely, a right hemisphere CVA
127.86 -> affects the left side of our body.
130.07 -> So, again, patients can have a paralysis
132.99 -> or weakness on the left
side of their body.
137.01 -> Patients with right hemisphere strokes
140.26 -> tend to have difficulty
with left visual fields.
145.12 -> So it can affect the left
visual field of each eye,
149.98 -> which can lead to what's
called left neglect,
152.83 -> meaning they just don't tend to see
155.09 -> or pay attention to the
left side of their body.
158.45 -> So these patients might run into things
161.35 -> in the left side of their room
163.07 -> or forget to put even makeup
166.21 -> on the left side of their face,
167.75 -> things like that.
169.39 -> Their left arm might be hanging
171.28 -> over the side of the wheelchair.
172.7 -> And they're kind of unaware
174.34 -> that it's not being intended to.
177.46 -> So that left neglect or left inattention
180.39 -> is a fairly common occurrence
182.06 -> with a right hemisphere stroke.
184.75 -> Another area that's often affected
187.81 -> in this area is what's called the Affect.
191.28 -> So patients can often appear,
195.07 -> kind of what we call flat affect,
196.81 -> meaning they don't show a lot of humor.
199.83 -> They don't often get jokes
201.61 -> or kind of some of those
abstract language ideas.
205.82 -> Conversely, they can have what's called
208.54 -> emotional lability, meaning they might
211.5 -> laugh inappropriately
or cry inappropriately
215.39 -> or cry quite a bit,
218.34 -> as a result of their stroke.
221 -> It's very common for patients
222.6 -> to have a left sided facial weakness,
225.35 -> which can lead to swallowing.
226.9 -> So swallowing deficits following
228.58 -> a right hemisphere stroke are very common.
232 -> Memory is often affected
234.5 -> by a right hemisphere stroke.
237.46 -> So these are some common characteristics
240.76 -> of a right hemisphere dysfunction
242.49 -> or a right hemisphere stroke.
245.13 -> So the brain has an amazing ability
248.1 -> to rewire itself
251.46 -> and relearn new areas.
255.32 -> So it's integral for a rehab team
258.46 -> to be involved following a stroke,
261.4 -> to begin that rehab process
263.39 -> and retraining the brain
266.764 -> to learn new techniques on how to function
270.31 -> for that part of the
brain that was affected
272.27 -> as a result of a stroke.
274.56 -> I hope this has explained
a little bit better,
277.07 -> the differences in common characteristics
279.62 -> between a right hemisphere
281.05 -> versus a left hemisphere stroke.
284.448 -> (energetic whooshing)
