Flashcards in 2. Cognitive Exam Deck (101)
inability to perceive/understand the import of sensory stimuli despite intact sensory mechanisms. perception devoid of meaning.
inability to recognize own neurological deficit.
inability to perform learned actions despite intact motor functions
define receptive aphasia
inability to understand. characteristic of Wernicke's
define expressive aphasia
inability to express via speech. characteristic of Broca's
define global aphasia
inability to comprehend, produce, repeat speech.
visual agnosia. inability to read.
inability to write. Akin to expressive aphasia
frontal lobe lesion accompanied by inappropriateness, etc
anomia, difficulty naming items
well-articulated but incorrect words. includes neologisms, semantic paraphasia, phonemic paraphasia
Language: bilateral or unilateral?
attention to the non-dominant world: bilateral or unilateral?
somatic sensation: bilateral or unilateral?
vision: bilateral or unilateral?
voluntary motor function: bilateral or unilateral?
hearing: bilateral or unilateral?
bi (Heschel's gyrus)
short term memory: bilateral or unilateral?
bi (medial temopral lobe)
frontal lobe functions (mood, behavior, emotional control, motivation, exec function): bilateral or unilateral?
long-term memory: bilateral or unilateral?
visuospatial function: bilateral or unilateral?
bi. parietal lobe
aphasia is lateralized where?
to the dominant hemisphere
patients with Broca's, Wernicke's, global and conductive aphasias will be unable to do what?
repeat complex phrases
Broca's area infarction results in what?
very reduced speech, repetition and naming. intact aud and visual language comprehension (reading). frustration.
Wernicke's area infarction results in what?
output that is active but nonsensical, inability to comprehend language. inability to repeat and name things. not frustrated.
conduction aphasia is due to a lesion where?
define conduction aphasia
reasonably normal expression and comprehension, but impaired repetition of simple and complex phrases.
Inability to repeat due to interruption of the arcuate fasciculus. Fluent, but with paraphasias. Comprehension may be OK.
damage to the dominant occipital lobe and splenium of the corpus callosum yields what?
alexia without agraphia. can write but can't read what they're written
immediate recall occurs where?
