Alzheimer's Disease Flashcards
A step-wise, sudden deterioration in cognition including episodes of confusion , aphasia, and slurred speech
Cerebrovascular disease
A gradual on-set of short-term memory loss and functional impairment in more than 1 domain
Dementia
Acute cognitive impairment with clouded sensorium
delirium
Phenomenon that a high-frequency stimulus will change the neuron in a way in which the activity continues to be higher even with decreased stimulation
Long-term potentiation (LTP)
Alzheimer’s agent that is an uncompetitive NMDA receptor antagonist
Memantine
Area of the brain that contains the cell bodies of neurons that synthesize acetylcholine
basal forebrain nuclei
Cholinesterase that has a higher concentration in the brain and is relatively selective for acetylcholine
acertylcholinesterase
Function of acetylcholinesterases
terminate cholinergic transmission
acetylcholinesterase that is mainly localized in the peripheral tissues and glial cells and is relatively non-selective
butyrylcholinesterase
Isoform of acetylcholinesterase that is preferentially lost with Alzheimer’s progression
G4 (tetromer)
3 cholinesterase inhibitors commonly used in treatment of Alzheimer’s disease
- Donepezil
- Rivastigmine
- Galantamine
Cholinesterase inhibitor that is selective for AChE over BuChE
Donepezil
Cholinesterase inhibitor that is selective for both AChE and BuChE and has a greater potency for G1 than G4
Rivastigmine
Cholinesterase inhibitor that is 50x more selective for AChE over BuChE and is also a positive allosteric modulator of nicotinic acetylcholine receptors
Galantamine
Abnormality that occurs within neurons in Alzheimer’s disease
neurofibrillary tangles
