6- Degenerative Disease Flashcards
understand common symptoms and presentation of patients with delirium
1) fluctuating consciousness
2) impaired attention (can’t focus on salient aspects)
3) incoherent speech
4) toxic/metab causes
common symptoms and presentation of patients with dementia
normal LOC
trouble with memory,
visuospatial skills, complex cognition, emotion or personality INTEREFERES WITH usual social/occup function
deterioration of global intellectual ability
Features of Alzheimer’s disease
early memory and visuospatial (can’t put on clothes or can’t find new places) (problems
early memory and visuospatial problems

features of creutzfeldt-jakob disease
rapidly progressive dementia
myoclonus (high velocity twitching movements faster than volitional movements)
prion disease
rapidly progressive dementia
myoclonus
creutzfeldt jakob disease
define prion
where is it found in most human tissues?
disease due to?
small infectious pathogen with protein but no nucleic acid
found in normal CNS
conformational change in protein
common features of prion disease
method of spread
age of onset?
ataxia
abnormal movements
visuospatial/exec dysfunction, cognitive problem
sporadic, heritable, and transmissible
usu 55-65 y/o
how does vCJD differ from typical sporadic CJD
1) younger age at present
2) slower progression
describe kuru
transmitted by
early tremor
ataxia
dementia late in course
transmitted by ritual cannibalism
early tremor
ataxia
dementia late in course
kuru
describe gerstmann syndrome
AD
clumsiness
incoordination
gait ataxia
variation within family
AD

fatal familial insomnia
onset age?
AD
35-60 y/o
insomnia, memory loss, confusion, hallucinations
insomnia, memory loss, confusion, hallucinations
fata familial insomnia
define neurodegenerative dz
spontaneous death of neurons
either due to intra/extracellular abnormal protein accum
clinical presentation of neurodegenerative disease
1) dementia = memory, language, exec fxn
depression, apathy, sociopathy
2) movement disorders= bradykinesia, rigidity, chorea, tremor
3) motor problems = weakness, atrophy
diseases under dementia
1) alzheimer’s
2) FTD
3) lewy body
4) huntington’s
5) CJD
diseases under movement
1) parkinson’s
2) PSP
3) CJD
4) huntington’s
diseases under motor problems

FTD
classic findings of alzheimer’s neuropath
NEED BOTH
neuritic (amyloid plaques and neurofibrillary tangles
diffuse atrophy (hydrocephalus ex vacuo)
spares deep structures

alzheimer’s
4 different FTD pathologies
if have tau-reactive intraneuronal inclusions then
1) neurofibrillary tangles (tau deposits)
2) ubiquitin inclusions
–> pick bodies
dementa wtihout histo features (decr neuron and cortex)
