COTE (OC) Flashcards
How does frontotemporal dementia usually present?
- gradual onset personality changes
- Memory and visuospatial skills remain
In vascular dementia what is seen in the progress of the patient’s condition?
Since it is based on mini-strokes, patient will have sudden mini decreases in health
What might we see in lewy body dementia?
- Motor symptoms over memory loss
- Freindly hallucinations
- Tremor/shuffle gaint (similar to parkinsons)
What medication classes are used for dementia (give examples)
- Cholinesterase inhibitors
(donepezil, rivastigmine galantamine,) - NMDA antagonists
(memantine) (like ketamine)
(stops uptake of calcium from blocking glutamate)
Way to remember the cholinesterases?
Riva(stigmine) in Don(epezil) eGala(ntamine)
What is olanzapine?
An antipyschotic (2nd gen)
What considerations are there with antipsychotics & dementia?
- Increases risk of mortality
- Only to be used with patients at high risk of harming themselves
The term lewy body dementia covers two types of dementia? What are they
- Parkinson’s dementia
- Dementia with lewy bodies
What is the difference between parkinsons dementia and dementia with lewy bodies?
Parkinsons dementia is when the memory and thinking issues come on a year later than the movement issues
Whereas D w/ LB sametime with parkinsons
what is amaurosis fugax?
sudden loss of vision in one or both eye(s), caused by an infarct in the retinal artery(ies).
classically - curtain coming down.
give three adverse effects due to the difficulty in achieving steady dose of levodopa for Parkinson’s
- combined with decarboxylase inhibitor (e.g. carbidopa)
- dyskinesia at peak dose (writhing movements),
- on-off effect, large variation in motor performance
list some alternative drugs (i.e. not L dopa) for Parkinson’s treatment
- MAO-B inhibitors (stops MAO from recycling old dopamine)
- COMT Inhibitors (similarly needed like decarboxylase inhibs to prevent peripheral breakdown)
- Dopamine agonists
what possible side effects might you see in a patient on a dopamine receptor agonist?
(e.g. bromocriptine, ropinirole, cabergoline, apomorphine)
- impulse control disorders
- excessive daytime somnolence
- hallucinations in older people
(also: nasal congestion, postural hypotension)
