Neurocognitive Flashcards
delirium
disturbance in attention and awareness and change in cognition that develop rapidly over short period
delirious speech
rambling, irrelevant, pressure, incoherent and unpredictably switches from subject to subject
onset of delirium
brief - rarely more than one month
symptoms usually diminish over 3-7 day period, up to 2 weeks
factors affecting risk of delirium
system infection febrile illness metabolic DO - hypoxia, hypercarbia, hypoglycemia hepatic encephalopathy head trauma seizure migraine brain abscess stroke postop states electrolyte imbalance
aphasia
inability to speak
apraxia
inability to carry out motor activities
confabulation
creating imaginary events to fill in memory gaps. usually in mild to moderate cognitive decline
sun downing
symptoms seems to worsen in the late afternoon and evening
stages of major NCD
- no sx
- forgetfulness
- mild cognitive decline
- mild to moderate decline - forget major events, declining ability to perform tasks, confabulation
- moderate decline - lose ability to perform some ADL, disorientation, loss of names, addy. frustration and w/d from others
- moderate to severe - incontinence, wandering, insomnia, disorientation, ADL only with assistance, agitation and aggression, sun-downing.
- severe decline - bedfast, aphasic, no recognition, decubiti, contractures
onset of AD
slow and insidious
etiology of AD
- ach alterations - decrease
- plaques and tangles (amyloid beta and tau protein)
- head trauma
- genetic factors
Pick’s DO
shrinking of the frontal and temporal anterior lobes of the brain
genetic etiology?
Pick’s sx
2 patterns:
- behavioral and personality changes - inappropriate, lack of judgement and inhibition. repetitive compulsive beh.
- speech and language problems - difficulty understanding written and spoken
which sx if most common following head trauma
amnesia
dementia pugilistica
syndrome characterized by emotional lability, dysarthria, ataxia and impulsivity
lewy body sx
rapid progression
earlier appearance of visual hallucination and parkinsonian features
lewy bodies
eosinophilic inclusion bodies seen in cerebral cortex and brainstem
ataxia
motor incoordination
huntington’s sx
involuntary twitching of limbs or facial muscles mild cog changes depression occurs between 30 and 50 ataxia
prion sx
rapid progression insidious onset motor features of prion dz - myoclonus, ataxia, biomarker involuntary movements muscle rigidity 40-60 years
psuedodementia
depression
meds for cog impairment
donepezil (aricept)
revastigmine (exelon)
Galantamine (razadyne)
memantine (namenda)
meds for agitation
olanzapine (zyprexa)
quetiapine (seroquel)
Haloperidol (haldol)
risperidone (resperidal)
which med for cog impairment is an NMDA receptor agonist
memantine (namenda)
