Strokes

Question 1

Middle Cerebral Artery (Left hemisphere)

Answer 1

• Contralateral hemiplegia/ hemiparesis (primary motor cortex)
• Contralateral Hemisensory Loss (Primary Somatosensory Cortex)
• Wernicke’s Aphasia (Inferior Parietal/Posterior Superior Temporal Gyrus)
• Cognitive and Perceptual Deficits
• Apraxias: Ideomotor and Ideational

Question 2

Middle Cerebral Artery (Right hemisphere)

Answer 2

contralateral hemiplegia (primary motor cortex)
contralateral hemisensory loss (primary somatosensory cortext)
perceptual deficits and left neglect syndromes (parietal)

Question 3

Posterior cerebral artery (pca)

Answer 3

• Memory Deficits (Temporal Lobe)
• Visual and Perceptual Deficits (Occipital Lobe)
• Visual Receptive Sensory Field Deficits or Visual Field Cuts
• Hemianopsias or Anopsias versus Neglect Syndromes

Question 4

Anterior Cerebral Artery (aca)

Answer 4

contralateral hemi (primary motor cortex)
contralateral hemisensory loss (pri somatosensory cortex)
cognitive and executive functions deficits (frontal lobe)
apraxia (premotor and supplementary motor cortex

Question 5

Posterior Inferior Cerebellar Artery (PICA)

Answer 5

-Ipsilateral hypertonicity -Vertigo, Nausea, Nystagmus

Question 6

Anterior Inferior Cerebellar Artery (AICA) and

Superior Cerebellar Artery (SCA)

Answer 6

-Ipsilateral hypertonicity
-Dysmetria, dysdiadochokinesia, Ataxia, Incoordination, Dysarthria,
Intention Tremor, Impaired Muscle Tone, Ataxic Gait
They lose proprioception
-Pts work hard to “feel the floor”
-Not smooth rhythmic steps

Question 7

Vertebral artery (brain stem)

Answer 7

-visual deficits (occipital lobe), ataxic gait,
vegetative state
-coma

Question 8

Basal Ganglia Disorders

Answer 8

parkinsons disease, cogwheel rigidity, brady kinesia, resting tremor,

Question 9

Disorders of cerebellum

Answer 9

posterior lobe- ataxic gait and ataxia, dysmetria, disdadochokinesia, intention tremor, rebound phenomenon

Question 10

motor assessments for cerebral dysfunction

Answer 10

intention tremor, postural tremor, dysmetria, ataxia and ataxic gait
