one or two copies of Apolipo-protein E4)
What happens to the acetylcholine in Alzheimer’s Disease?
DECREASES
What neurotransmitter increases with Alzheimer’s Disease?
Glutamate
What happens during the mild stage of the Alzheimer’s Disease? (3)
-Short Term Memory Loss
-Lost in familiar event
-Lose Self management skills
What happens during the moderate stage of the Alzheimer’s Disease? (3)

-Lost the ability to recognize family and friends
-Unconsciously fill in memory gaps with imaginary event
What happens during the severe stage of the Alzheimer’s Disease?
-Lose the ability to eat, speak, understand language, ambulate, and control elimination
What are the 3 medical options for the Alzheimer’s Disease?
Cholinesterase Inhibitor
Memantine
Atypical Antipsychotics
(Risperidone + Olanzapine)
Most common cholinesterase inhibitor?
DONEPEZIL
When is Donepezil prescribed?
All stages of the Alzheimer’s Disease
What is the mechanism of action of the Alzheimer’s Disease?
Alzheimer’s Disease damages neurons that releases acetylcholine
What does Donezepil do?
it breaks the enzyme that breaks down acetylcholine
What happens to acetycholine when you take Donepezil?
INCREASES
Does alzheimer’s disease slows the progression of disease?
NO
-it only temporarily improves clients memories = neurons keep dying
How is Donepezil differ from other cholinesterase inhibitor?
It crosses BBB
True or False? Donepezil is a cholinergic medication
TRUE
What are the adverse effect of taking Donepezil
-Urinary Frequency
-Nausea
-Vomiting
-Diarrhea
-GI issues
-Watery Eyes
-Too much Saliva
What is the rare effect of taking Donepezil?
Bradycardia
Patient taking Donepezil would experience Bardycardia when ______
Patient is taking medication that decreases the heart rate
What kind of medication should you take with Donepezil?
Anticholinergic medications
What medications should the client avoid when taking Donepezil
TCA
Oxybutynin
Older antihistamines
True or False? Donepezil does not stop or slow down the progression of Alzheimer’s Disease
True
Why is Donepezil prescribed?
-Cheap
-Well tolerated
-Patient can experience a period of improvement
How is Memantine prescribed?
For moderate and severe stages of Alzheimer’s Disease
What does Myasthenia Gravis do to acetylcholine receptors?
Attacks it on skeletal muscle
What happens during Myasthenic Crisis?
Client experience EXTREME muscle wellness and may stop breathing
What are the 2 Medication Option for Myasthenia gravis?
- Cholinesterase Inhibitor
- Immunosuppressive Drugs (Prednisone)
What are the 2 Cholinesterase Inhibitor for Myasthenia Gravis?
- Neostigmine
- Pyridostigmine
Aside from treating Myasthenia Gravis, what does neostigmine and pyridostigmine do?
Reverse Nondepolarizing Neuromascular blocking agents AFTER SURGERY
What releases acetylcholine?
Motor Neurons = causes Muscle Contraction
In Myasthenia Gravis, what happens after the acetylcholine is released
Cholinesterase (enzyme) QUICKLY breaks down acetylcholine
What does cholinesterase inhibitor do to cholinesterase?
TEMPORARILY binds to cholinesterase, SLOWING IT DOWN
What happens when there is an increase in acetylcholine?
STRONG MSUCULAR CONTRACTION
Cholinesterase I. can be give PO, what should you asses before giving it?
Person’s ability to swallow
-Ask the client to take few sips of water, If the client has difficulty, request PARENTERAL Form
What are the signs of UNDER MEDICATION of Cholinesterase Inhibiotr (MG)
-Ptosis
-Difficulty Swallowing
What are the signs of OVERMEDICATION for Cholinesterase I. (MG)
Excessive Salivation
SYMPTOPMS of CHOLINERGIC CRISIS
S - salivation
L - lacrimation (excessive tearing)
U - urination
D - diaphoresis / diarrhea
G - gastrointestinal cramping
E - emesis (vomitting)
3B’s

2. Bronchospasm
3. Bronchorrhea
Which part of the brain does Alzheimer’s disease begin to damage?
Hippocampus - associated with LEARNING and MEMORY
what happens to the cerebral cortex of a person with Alzheimer’s disease?
Cortex is Dying = neuronal death
