(Lesson 2) - Answer: Ischemic: 87%
-Thrombotic
-Embolic
-Lacunar
Hemorrhagic: 13%
-Intracerebral
-Subarachnoid
Thrombotic Stroke (Ischemic) - Answer: 48% of all strokes
-typically occurs during sleep
Page 1 of 72
,-slow progressive onset of deficits
-50% are associated with prior TIA
Embolic Stroke (Ischemic) - Answer: 26% of all strokes
-typically occurs while awake
-sudden, immediate deficits (sometimes seizures)
-11% are associated with prior TIA
Lucunar Stroke (Ischemic)
small vessel disease - Answer: 13% of all strokes
-small infarct (>15-20 cm) deep in the brain
-onset can be gradual or sudden
-23% associated with proceeding TIA
-often pure sensory or motor symptoms
-typically no higher cortical functional involved
Intracerebral Hemmorhage (ICH) - Answer: 10% of all strokes
-90% happen with the patient is under "no stress"
-major cause of "hypertension"
-onset may be gradual or sudden
-8% are associated with prior TIA
-direct correlation with high blood pressure/ hypertension
Subarachnoid Hemorrhage (SAH) - Answer: 3% of all stroke
-occurs often during strenuous activity

,-cause: rupture aneurysms and vascular malformations
-sudden onset
-7% are associated with preceding TIA
Left Stroke with Right Hemiplegia - Answer: -Language/Perceptual problems
-expressive aphasia
-receptive aphasia
-global aphasia
-alexia, agraphia , acalculia
-apraxias: motor planning perceptual problems
(Impaired verbal and math skills with word letter discrimination
Left Stroke with Right Hemiplegia (BEHAVIORS) - Answer: -Slow, anxious, cautious,
normal attention span

, -perceptual language disorders
language
Right Stroke with Left Hemiplegia (BEHAVIORS) - Answer: -fast and impulsive
-short attention span
-overestimate abilities/ judgement
-denial of illness (anosognosia)
-lack of inhibition
-inability to express emotions /affect is flat
Cerebrum - Answer: -frontal, parietal, temporal, and occipital lobes
-consisting of two hemispheres, left and right, separated by a fissure
-responsible for the integration of complex sensory and neural functions and the
initiation and coordination of voluntary activity in the body.
initiates and coordinates movement and regulates temperature. Other areas of
the cerebrum enable speech, judgment, thinking and reasoning, problem-solving,
emotions and learning.
Frontal Lobe - Answer: -controls voluntary movement
-thinking problem solving
-reasoning judgement
-personality
Primary Motor Cortex
(motor homunculus) - Answer: -located on the pre-central gyrus
