Sketchy Path: Neuro - "Alzheimer Disease and Dementia" Flashcards
Dementia is _____________________.
a chronic degeneration in at least one cognitive ability –memory, speech, attention–with clear consciousness
___________ leads to Alzheimer’s as early as 35.
Down syndrome (like the model for the new DOWNtown with the kid holding the APP crown)
Mutations in ______________ lead to increased risk of early-onset Alzheimer disease.
presenilin 1 and 2 (like the two princes fighting over the beta cloak with 1 and 2 on their tunics)
Being ____________ in apo E4 increases risk of late-onset AD.
homozygous
Think of the 4 E’s.
Which plaques are extracellular?
Beta amyloid (like the betas on the external cape)
The tau plaques are intracellular (like the purple taus on the central aspect of the king’s body).
Alzheimer’s presents with marked atrophy in the ______________.
hippocampi (like the two seahorses on the Earl’s jacket)
Alzheimer’s has low levels of which neurotransmitter?
Acetylcholine (particularly in the nucelus basalis of maynart)
(Think of the empty bottle of acetylcola.)
The two early features of Alzheimer’s are ________________.
short-term memory loss and visuospatial difficulties (like the Recent Events magazine and map that the king is holding)
Language, personality, and social function are preserved until late.
Frontotemporal dementia has what inheritance pattern?
AD (like the domino suit worn by the jester)
FTD primarily affects which functions?
Language and personality (not memory!)
Think of the jester with the hand over his mouth and the bizarre face on a stick.
FTD has what kind of protein deposit?
Tau (like the Tau beneath the jester’s cups that you PICK… get it?)
FTD is associated with what other neurologic disorder?
ALS (like the spine image on his collar with frayed edges)
Lewy body dementia presents with ______________ in the cells.
alpha-synuclein (Lewy bodies)
Think of the alpha on the dead king Lewy’s grave.
DLB presents with dementia, ____________, and ____________.
hallucinations; Parkinson’s
Think of the cogwheels on the grave and the demons in the painting.
What cells are seen in HIV dementia?
Microglial cells with multiple nuclei
Think of the cages with demons with multiple eyes.
