dementia
most common form of dementia
alzheimer’s (60-80%)
How many areas of cognition need to be impaired for diagnosis of Alzheimer’s?
two
Earliest sign of Alzheimer’s
short-term memory loss
MRI finding that suggests AD
bilateral hippocampal atrophy
Scoring assessment of mini-mental status exam (MMSE)
20-26: mild functional dependence. 10-20: moderate dependence. Score < 10: severe, total dependence
Neuropathological hallmarks of AD
Amyloid-rich senile plaques, Neurofibrillary tangles, Neuronal degeneration
most common functioning deficit for patient’s at stage 4 of AD
decreased ability to manage instrumental (complex) activities of daily life.
characteristic functional change of stage 5 of AD
deficits in basic activities of daily life and can’t recall major events

cannot perform basic activities without help and cannot live at home without assistance. lasts 2.5 yrs
characteristic function changes of stage 7 of AD
inability to speak, walk, or sit up on their own. lasts 1 yr
most frequent cause of death of AD
aspiration pneumonia
MOA of cholinesterase inhibitors
curb the breakdown of acetylcholine
What is the only tx approved by FDA for all stages of Alzheimer’s?
Donepezil (Aricept)
Cholinesterase Inhibitors
Donepezil (Aricept), Rivastigmine (Exelon), Galantamine (Reminyl)/Razadyne
Cholinesterase inhibitor CI with severe renal or hepatic impairment
Galantamine (Reminyl)/Razadyne
MOA of NMDA receptor antagonists
protective role in the brain by regulating the activity of a glutamate.
NMDA receptor antagonists
Memantine (Namenda)
Supplement that may be helpful with Alzheimers due to antioxidant properties
vitamin E
SSRIs recommended for AD to treat depression or behavioral sx
sertraline (Zoloft), Paroxetine (Paxil), Citalopram (Celexa)
Anxiolytics helpful for anxiety, restlessness, verbally disruptive behavior and resistance in AD
lorazepam (Ativan) and oxazepam (Serax)
Pattern of deterioration associated with vascular dementia compared to AD
vascular is abrut, fluctuating or stepwise deterioration whereas AD is progressive
Characterized by focal atrophy of the frontal and temporal lobes
frontotemporal dementia
Characterized pathologically by the presence of Pick bodies in the neocortex and hippocampus.
Pick’s disease (subtype of FTD)
