Disorder - characteristics - hemisphere

Question 1

Aphasia

• fluent
• nonfluent

Answer 1

impaired LEFT SIDE

fluent
= Wernicke’s aphasia
difficulty understanding speech

nonfluent
= Broca’s aphasia
difficulty producing speech

Question 2

Apraxia

- ideomotor

Answer 2

impaired LEFT SIDE

• posterior left parietal lesion
• disruption of parietofrontal connections
• patients are unable to copy movements or make gestures

Question 3

Aprosody

- auditory

Answer 3

impaired RIGHT SIDE

• severe limitation in interpretation of intonation and pitch
• monotonous speech + difficulty singing

Question 4

Alexia
- pure

think - dyslexia

Answer 4

impaired LEFT SIDE

• impaired ability to read aloud
• understanding the meaning of written words

Question 5

Agraphia

Answer 5

impaired LEFT side

• impaired ability to write

Question 6

Alcalculia

Answer 6

impaired LEFT side
- left parietal lesions

-> impaired a bility to perform mathematical calculations

Question 7

Object at the right side of the visual field is named

but object at the left visual field isn’t

Answer 7

impaired communication between LH and RH

- information from the left visual field can’t reach the RH via the CORPUS CALLOSUM

Question 8

Severe limitation in movements within spatial patterns

Answer 8

impaired RIGHT side

-> can’t walk in a straight line / grasp at objects

Question 9

Words spoken into the left ear are not recognized

Words spoken into the right ear are recognized

Answer 9

impaired communication between LH + RH

• > words from left ear can’t reach LH via corpus callosum
• > words from right ear directly processed by LH

Question 10

Hands are unable to work together

• > left hand doesn’t know where right hand is
• > vice versa

Answer 10

impaired communication between LH + RH

-> one hemisphere isn’t receiving info about the task from other hemisphere

Question 11

Spatial tasks are executed poorly when objects are presented to the right visual field - LH

But not when objects are presented to the left visual field - RH

Answer 11

impaired communication between LH + RH

-> impaired ability to recognize spatial relations + fore/background + geometrical ratios

Question 12

Neglect of left sided perception/surroundings

Answer 12

impaired RIGHT side
- right parietal lesions

-> neglect of left side of the visual field

Question 13

Severe limitation in mental figure rotation

Answer 13

impaired RIGHT side

-> inability to recognize objects given from an unusual perspective/angle

Question 14

Severely impaired recall - memory - for what has been said

Answer 14

impaired LEFT side

-> impaired immediate recall
