Biological Bases of Behavior IV: Cognitive Disorders Flashcards
rare dementia that is clinically indistinguishable from Alzheimer’s
Pick’s disease
primary neurotransmitter involved in delerium
acetylcholine
type of amnesia in korsakoff’s
anterograde
Parkinson’s is associated with degeneration of
neurons in the substantia nigra, which is in the basal ganglia
amnesia in concussions
retrograde- events just before the injury and the incident itself
intact language comprehension, speak fluently, able to execute verbal commands, but can’t repeat verbal phrases
conduction aphasia
where are plaques and tangles observed in alzheimer’s?
hippocampus and amygdala
indications of pseudodementia
acute onset with precise date, rapid progression, insight into issues
Parkinson’s dementia affects
speed of processing and executive functions
the onset of vascular dementia is
abrupt
thiamin deficiency leads to
korsakoff’s
used to treat movement components of Parkinson’s
levadopa
lack of awareness of a disability
anosagnosia
slow writhing movements
athetosis
prosopagnosia is caused by
injury to the visual association cortex
acquired partial or complete inability to read
alexia
Wernicke’s aphasia results from lesions to the
left temporal lobe
lack of foresight and concern, irresponsibility, loss of insight
frontal lobe syndrome from injury at the site of a coup or countrecoup
Neurotransmitters implicated in Huntington’s
acetylcholine and GABA
choreiform movements, athetosis, facial grimaces
Huntington’s
bradykinesia
slowed initiation of movement
severe problems with articulation, making speech slow and effortful, with intact comprehension
Broca’s
