Exam 1 (weeks 1-3) Flashcards
Cog-Com skills
problem-solving, planning, decision-making, behavior regulation, social communication
Associated cognitive function
Attention, memory, reasoning, inferencing, abstract thinking, etc.
Associated communication function
Prosody, facial expression, social scripts, turn taking, non-literal language, etc.
Cognitive Communication
- language in use, not structure
- functional communication
- cognitive processes supporting functional communication
- neurological structure and functions supporting cognitive processes
functional communication
- communicating wants and needs
- communicating emotional state appropriately
- taking social context into account
Injuries that cause cog-com dis
- cerebrovascular accident (CVA), aka stoke
- trauma
- sudden onset, subsequent recovery
CVA (stroke)
- caused by clot or hemorrhage
- disrupt blood flow and cause cell death
- localized damage
trauma
- closed or open (through dura) head injury
- penetrating (always open) or blunt (either)
- impact and movement cause causes cell death
- swelling, bleeding, and neurochemical changes exacerbate and can have global impact
Disease that cause cog-com
- multiple possible disease processes
- micro changes lead to macro differences
- progressive deterioation
multiple possible diseases process
- multi-infarct
- protein clumps or other cell abnormalities
- lead to cell death and atrophy
Micro-changes lead to macro differences
global impact possible
causes of cog-com dis
CVA, trauma, and disease
cognitive communication profiles
- dementia
- traumatic brain injury (TBI)
right hemisphere disorder (RHD)
not a one to one correspondence
- CVA and trauma can lead to RHD or TBI
- Multiple CVA and repeated trauma can lead to dementia
Hippocampus
the main area for memory formation
damage to fornix
results in amnesia, important structure for memory formation
occipital lobe
vision- in between preoccipital notch and the parieto-occipital sulcus
parietal lobe
- somatosensory (post central )
- sensory homunculus
- pain and temperature
- integrative! (making sense of signals)
temporal lobe
- receptive language (left side only)
- memory
- hearing (auditory processing cortex)
frontal lobe
- executive function
- primary motor (precentral gyrus)
- expressive language
- Brocas area
- memory attention, decision making, impulse control
Limbic system
- emotion regulation
- memory consolidation (Papez)
basal ganglia
motor coordination/ feedback loop
cerebellum
- memory/sensory (proprioception) integration
- cognitive involvement
Meninges
- skull
- dura mater (outermost layer)
- arachnoid (blood vessel)
- subarachnoid space (present) where the cerebralspinal fluid lives
- pia mater
