25
When imaging Alzheimer's disease, amyloid plaque deposition will be seen in this type of scan
PET
26
Does this describe dementia, pseudodementia, or normal aging: Severe memory loss with decrease in IQ
Dementia
27
Does this describe dementia, pseudodementia, or normal aging: Moderate memory loss with no change in IQ
Pseudodementia (depression that mimics dementia)
28
Does this describe dementia, pseudodementia, or normal aging: Minor forgetfulness with no change in IQ and no disruption of normal life
Normal aging
29
This measure is decreased in dementia but not pseudodementia or normal aging
IQ
30
Centrally acting inhibitors of this enzyme may be used to treat Alzheimer's disease
Cholinesterase (Increase and prolong acetylcholine concentrations at the synapse)
31
This is an NMDA receptor antagonist that may be used to treat Alzheimer's disease
Memantine
32
Donepezil is a centrally acting inhibitor of this enzyme, and can be used to treat Alzheimer's disease
Cholinesterase
33
Rivastigmine is a centrally acting inhibitor of this enzyme, and can be used to treat Alzheimer's disease
Cholinesterase
34
This is the preferred formulation of centrally acting cholinesterase inhibitors in Alzheimer's disease
Rivastigmine Patch
35
The presumed MOA of this drug in Alzheimer's disease is reduction in glutamatergic overstimulation at the NMDA receptor
Memantine
36
What is the MOA of Memantine in Alzheimer's disease?
Reduction in glutamatergic overstimulation at the NMDA receptor
37
These receptors in CNS appear critical for memory formation, but overstimulation is damaging
Glutamate
38
This type of drug for Alzheimer's disease has a black box warning of increased risk of death by cardiovascular or infectious diseases in elderly demented patients (risk highest in patients with Lewy body dementia)
Antipsychotics
39
Antipsychotics have a black box warning of increased risk of death from these diseases in elderly demented patients
Cardiovascular / infectious diseases
40
Type of dementia characterized by impaired attention, early language changes, and memory can be intact
Fronto-temporal dementia
41
Type of dementia that is more likely to have concurrent motor deficits
Vascular dementia
42
Vascular dementia is more likely to have concurrent deficits of this type
Motor
43
Dementia that must have attention and executive function deficits, and delayed memory impairment
Dementia with Lewy Bodies
44
In Dementia with lewy bodies, this impairment must be delayed
Memory
45
Patients with this type of dementia may have fluctuating cognition, recurrent visual hallucinations, REM sleep disruptions early in disease, and spontaneous features of parkinsonism
Dementia with lewy bodies
46
Type of dementia with gradual progressive decline of general memory
Alzheimer's disease
47
Type of dementia that may be acute with recovery sometimes
Vascular
48
Type of dementia that may have visual hallucinations
Lewy body
49
Parkinson's develops about a year into disease with this type of dementia
Lewy body
50
This condition develops about a year into disease with Dementia with lewy bodies
Parkinson's
51
Type of dementia characterized by deficits in attention, language changes, early and odd behaviors often noted
Frontotemporal
52
Is delirium acute or delayed onset?
Acute and sudden
53
This condition is a disturbance in attention and awareness that develops over a short period of time and tends to fluctuate
Delirium
54
What are the two requirements of a delirium diagnosis?
Acute onset and fluctuating course Inattention
55
Is there reduced consciousness in delirium?
Yes
56
Is there reduced consciousness in dementia?
No
57
Is delirium short or long duration?
Brief
58
Is there disorganized speech in delirium?
Yes
59
Is there disorganized speech in dementia?
Mostly no (aphasia or anomia in severe states)
60
Haloperidol is first-line therapy for this
Hyperactive delirium
61
This drug is the first-line therapy for hyperactive delirium
Haloperidol
62
This drug should be avoided in delirium due to its ability to worsen confusion, increase risk of falls, and disinhibited behaviors
Benzodiazepines
63
What drug should be avoided in the treatment of delirium?
Benzodiazepines
64
Risperidone, Quetiapine, Haloperidol, and Olanzapine are commonly used medications to treat this condition
