1

What's the most common cause of long term disability?

Stroke

2

What is a stroke?

Acute onset of neurologic dysfunction secondary to abnormality in cerebral circulation. Resultant symptoms correspond to the involvement of certain brain areas

3

What is a CVA?

Refers to symptoms, Problems in the brain
Terms are used interchangeably with stroke

4

What are the types of CVA?

Ischemic-tissue died due to lack of blood flow
Hemorrhage-abnormal bleeding
Atherosclerosis

5

How long do symptoms of TIA last?

1-24 hours
no permanent damage

6

What side does a CVA effect?

Right CVA = Left hemiporesis

7

What's in the Frontal Lobe?

Motor cortex and premotor cortex
Broca's area (motor aspects of speech)
Emotions & Behaviors
Personality
Inability to attend to a task

8

What happens when you have a problem in the frontal lobe?

Attention
Memory-(ability to store experiences and perceptions for later recall)
Confabulation (inappropriate words or fabricated stories)
Confusion
Perseveration (Repetition of words, thoughts or acts not related to a context)
Executive functions (planning, acting and performing a task)

9

What happens if there is damage in the pre-frontal cortex?

Impulsiveness
Impaired organization and sequencing
Impaired judgement

10

What is multi-infarct dementia?

Scattered areas of brain are damaged

11

What is delirium?

Acute confused state

12

What does the temporal lobe consist of?

Auditory cortex
Wernicke's area (language reception & comprehension)

13

What are the types of Aphasia?

Receptive Aphasia (Wernicke's) = Difficulty understanding spoken or written words
Expressive Aphasia (Brocca's) = Inability to speak or express language
Global - impairments in both

14

What is Dysphagia?

Difficulty swallowing

15

What happens when there are problems in the parietal lobe?

Neglect (ignore the affected side of body)
Sensory cortex and somatosensory cortex
Perception and spatial relationships
Integrates sensory and visual information (Aphasia, Agnosia-ability to identify common objects by feeling it)

16

What is apraxia?

Deficits in motor planning
-Unable to complete sequence
-May take longer to learn task
-difficulty initiating and performing a task

17

What are the types of Apraxia?

Ideomotor - Can't perform a task when asked, but can do it automatically
Ideational - Purposeful movements not possible (automatically or on command)

18

What is Dysarthria?

Lesion in a location that mediates speech production
Volitional and automatic actions impaired (chewing, swallowing, slurred speech)

19

What is neglect?

Patient does not register stimuli from one side of the body
(vision may be intact but cant process info)
Denial of deficits are often present

20

What is in the occipital lobe?

Primary visual cortex and visual association area

21

What are some problems if the stroke is in the occipital lobe?

Visual field cuts
Hallucinations & Illusions

22

What is a Homonymous hemianopsia?

Pt will have deficits on right or left of both sides of eye

23

What happens with a Cerebellum stroke?

Ipsilateral problems
Coordinates voluntary movement
Balance and equlibrium
Dysdiadochokinesis-(rapid alternating movement)

24

What happens with brain stem strokes?

Attention, arousal and consciousness go out

25

What is Ataxia?

Drunken sailor gait (need to call a taxi)

26

Where do most of the problems occur in the brain?

Circle of willis
(Middle cerebral Artery)

27

What does the middle cerebral artery (MCA) supply?

Frontal, parietal, temporal lobes

28

What will you see with a MCA stroke?

Contralateral hemiparesis
Aphasia (Wernicke's and brocca's)
Ataxia (drunken sailor gait)
Neglect
Loss of depth perception
Agnosia (inability to process sensory info, can't tell what object is by feeling it)
Contralateral homonymous hemianopsia
The more proximal the infarct the more extensive the damage

29

What does the anterior cerebral artery (ACA) supply?

Frontal and Parietal

30

What will you see with a ACA stroke?

Contralateral hemiparesis and sensory loss
Urinary incontinence
Problems with imitation and bimanual tasks
Apraxia - deficits in motor planning
