Cognition & Aphasia Flashcards
Focused attention
The ability to focus on and respond to stimuli and information
Sustained Attention
The ability to sustain or hold and manipulate information
Selective attention
The ability to attend and ‘select’ information within a larger set
Alternating attention
The ability to switch or alternate attention between tasks
Divided attention
The ability to attend and divide focus on multiple things at once
Right Hemisphere Disorder
- Visuospatial deficits
- Anosognosia: denial
- Prosodic, inferencing; and discourse deficits
- Sustained and selective attention deficits
Damage to frontal lobe results in:
- Executive functioning deficits
- Memory loss
- Motor planning/programming
Damage to parietal lobe results in:
- sensory deficits
- difficulty reading/writing
- mathematical deficits
Damage to temporal results in:
- deficits in auditory perception/sensation/integration
- categorization difficulties
Damage to Basal Ganglia results in:
- Hypokinetic dysarthria
- Hyperkinetic dysarthria
Damage to Hippocampus results in:
- Memory impairments
- Fears/anxieties may increase
Damage to Brainstem results in:
- attention deficits, consciousness, non-voluntary function damage
- CN damage = can present as dysarthria and/or dysphagia
- midbrain: Parkinson’s
Damage to cerebellum results in:
- motor coordination and balance deficits
- Ataxia (appearing drunk)
Damage to left hemisphere results in:
- expressive deficits
- receptive deficits
- global deficits
- cognitive impairment
- right visual field impairment
Difference between thrombosis and embolism
Thrombosis: blood clot in CEREBRAL blood vessels
Embolism: blood clot outside of CNS
