III: Acquired Communication Disorders Flashcards
(122 cards)
acquired LD
aphasia (4)
caused by acquired brain damage, language impairment NOT a speech impairment, intact nonverbal cognition and intelligence, anomia
acquired LD
grammatical competence (3)
the expression and comprehension of the formal grammatical aspects of language, syntax and morphology, deficits aka agrammatism
acquired LD
auditory comprehension (A/C) (1)
the ability to attach meaning to the words spoken by others
acquired LD
verbal repetition (2)
a skill to help differentiate the aphasia syndromes, repetition tasks: verbal short-term memory, verbal working memory
acquired LD
reading and writing deficits (6)
alexia, deep dyslexia (preserved whole word reading, difficulty with sound-by-sound), surface dyslexia (preserved sound-by-sound reading, difficulty with whole word), pure alexia without agraphia, letter-by-letter (LBL) reading, agraphia
acquired LD
persevervation (2)
inappropriate repetition of a response of continuation of a behavior when it is no longer required or appropriate, can be recurrent or continuous
acquired LD
recurrent vs continuous preservation
repeating a response to fill a delay :: immediately repeating a response without delay
acquired LD
stuck-in-set (1)
inability to shift response set when directed to (for example, stuck on counting when pt is asked to recite alphabet)
acquired LD
apraxia (1)
a disorder of the execution of a learned movement that is not cause by motor weakness, incoordination or sensory loss and it is not due to failure to understand the command
acquired LD
ideomotor apraxia (2)
most common particularly following left hemisphere strokes, difficulty with: selection, sequencing and spatial orientation of movements for gestures
acquired LD
AOS (2)*
apraxia of speech, a sensorimotor speech disorder with symptoms of impaired volitional production of articulation and prosody that does not result from: abnormal muscle strength, tone or timing NOR does it arise from aphasia, confusion, generalized intellectual impairment or hearing loss
*may co-occur in persons with aphasia
acquired LD
agnosia (3)
generally associated with cortical brain damage (parietal, temporal, occipital), not a result of primary sensory deficits, a disorder of recognition of: objects, people, sounds, colors, etc
acquired LD
prosopagnosia vs anosognosia
inability to recognize faces :: inability to recognize one’s own illness
acquired LD
language zone (2)*
fed by the middle cerebral artery (MCA) so often a left MCS stroke will result in an aphasia, includes: angular gyrus, broca’s area, wernicke’s area, arcuate fasciculus, supra marginal gyrus
*includes the cortical and subcortical regions of the frontal, parietal and temporal lobes of the left hemisphere
acquired LD
anterior vs posterior lesions (1::1)*
leads to confluent aphasia :: leads to fluent aphasia
*damage to both regions of the language zone of the left hemisphere may result in a severe aphasia with concomitant right hemiparesis
acquired LD
right hemiparesis (2)
impairment of motor functioning on the right side of the body, caused by damage to the motor strip (left pre central sulcus and deeper)
acquired LD
right hemiplegia (1)
paralysis on the right side of the body
acquired LD
etiologies (4)*
cerebrovascular disease (leading cause), TBI, brain tumor, neurodegenerative disorders
*damage occurs on the language zone of the left hemisphere
acquired LD
TIA (3)
transient ischemic attack, temporary loss of neurological function caused by interruption of blood flow to a brain region, warning sign for stroke
acquired LD
CVA (2)
cerebrovascular accident aka stroke, most common cause of aphasia
acquired LD
embolus vs thrombosis (1::1)*
blood clot formed in another body area and traveled up to the brain (usually from heart) :: blood clot formed in the brain
*each are considered occlusive strokes and may be treated using clot-bursting rugs such as TPA
acquired LD
hemorrhagic CVA (1)
rupture of vessels in the brain (rather than blockage of blood flow)
acquired LD
types of brain hemorrhages
ruptured aneurysm (ballooned-out area), arteriovenous malformation (AVM – tangled blood vessels usually congenital), intracerebral hemorrhage (rupture within neural tissue), subdural/subarachnoid hemorrhage (rupture in the meningeal coverings of the brain)
acquired LD
TBI (2)*
traumatic brain injury, damage may be focal or diffuse, causes include: motor vehicle accidents (MVAs), falls, head trauma, chronic traumatic encephalopathy (CTE – multiple concussions), blast injuries, gunshot/stab wounds, closed head injuries (CHIs)
*common site of damage is uni/bi-lateral prefrontal area(s)
