Gronseth Cognition Disorders Flashcards
What are some limitations of the mini mental status exam?
It is biased to test the posterior brain and dominant hemisphere
What side of the brain is dominant in most people
Left brain dominant: most right handed, 50% of left handed are left brian dom (25% are R brain dom and 25% are bilateral dom)
What cortex is important for learned motor behavior (eg: pole vaulting, writing, grabbing a hand)
Prefrontal cortex
what area of the brain is important for object recognition/facial recognition
Ventral Temporal lobe
What are of the brain is important for understanding the relationship between objects?
Dorsal Parietal lobe
What area of the limbic system is important for coding unexpected events?
Anterior Cingulate Gyrus
Whats an important way to distinguish between diffuse and focal lesions
whether fluency, comprehension, and repetition are all impacted
How do you differentiate from cortical vs subcortical dementia?
Cortical dementia (Alzheimer’s) does not present with motor symptoms whereas subcortical (Parkinson’s) presents with motor symptoms including rigidity/weakness
If someone presents with a dementia that’s affecting personality, what part of the brain is implicated in that?
Frontotemporal Dementia (Pick’s disease)
If a patient presents with focal lesiom symptoms but the MRI is clear for neoplasms and a stroke, what must you consider?
Focal cortical degeneration
what part of the underside of the brain is important for transferring the contralateral visual information to Wernicke’s area for comprehension?
The splenium that is anterior to the visual cortex
Brain area for behavior problems
prefrontal/frontal
Brain area for memorizing a list
medial limbic (papetz)
Brain area for balancing a check book
symbolic
brain area is someone can’t remember names
