29-dementia Flashcards
DSM V Criteria for Major Neurocognitive Disorder (previously termed “dementia”)
A. Evidence of significant cognitive decline from a previous level of performance in one or more cognitive domains: attention, , learning/memory, language, social cog, perceptual -motor
B. interfere with at least IADLS
C. not in context of delirium
D. not better explained by another mental disorder
labs to order to rule out physical causes of dementia
CBC, CMP calcium thyroid vitamin B12 deficiency testing Folate deficiency RPR
CT or MRI
what do white matter changes found on MRI indicate?
They represent microvascular disease, which may be caused by hypertension, smoking, obesity or simply by aging.
Commonly found in asymptomatic individuals and are often felt to be clinically irrelevant.
Clinical Dementia Rating 5 point scale (0-3)
0: No cognitive impairment
0. 5: Very mild dementia
1: Mild dementia
2: Moderate dementia
3: Severe dementia
Which bedside instruments used for diagnosing delirium does evidence best support?
Confusion Assessment Method (CAM)
Causes of delirium
UTI Urinary retention (BPH) Resp infection electrolyte dysfunction Pain Depression CV events Adverse drug effects withdrawal
air-bronchograms are pathognomonic for
pneumonia
Hospital Interventions That Can Prevent or Minimize Delirium
Frequent reorientation and redirection by a familiar provider (eg. one-to-one sitter instead of restraints)
Avoid medications that can lead to delirium
Provide early mobility and range of motion exercises
Minimize unnecessary lines, cables, and catheters
Provide increased stimulation- lighting! hearing aids!
max of acetaminophe dose
3-4 g
meds to help with Alzheimer’s
Four cholinesterase inhibitors (donepezil, rivastigmine, tacrine and galantamine)
memantine
atypical antipsychotics for behavioral disturbance
vitamin E and AD
controversial
delay in the onset of death, institutionalization, or progression to severe dementia
memantine MOA
NMDA receptor antagonist
does Cognitive rehabilitation therapy help AD?
no evidence
