Parkinson's Supplementary Flashcards
What 2 diagnostic tests can be helpful in Parkinson’s?
- structural brain imaging
- SPECT scan - a DatScan (dopamine injected and check where its picked up)
Men are ___ times more likely to develop Parkinsons than women.
1.5 times
List 5 risk factors for Parkinsons.
- advancing age
- positive family history
- being male
- genetics
- environment e.g. pesticide exposure
Symptomatic treatment for Parkinson’s disease aims to increase dopamine concn or stimulate dopamine receptors. List some drugs that can be used.
don’t use 3MB drug question use this
- levodopa
- dopamine agonists e.g. bromocriptine/ropinirole
- monoamine oxydase type B inhibitors
- amantadine
What enzyme converts levodopa to dopamine in the brain?
DOPA decarboxylase
What is a major side effects of dopamine agonist use?
impulsive and compulsive behavioural issue e.g. gambling, hypersexuality, binge eating
What do Lewy bodies contain?
alpha-synuclein
Define hypomimia, hypophonia and micographia - what symptom of Parkinson’s do they fall under?
- Hypomimia: decreased facial expression
- Hypophonia: soft speech
- Micographia: progressively smaller handwriting
- all types of Bradykinesia
Parkinson’s tremor persists in movement. True/false?
False
What are the most common Parkinson tremors? (3)
- pill-rolling
- finger flexion-extension
- finger abduction-adduction
Head tremors are not typical in PD but patients can get jaw, tongue and lower limb tremors. True/falsE?
True
List some red flags of PD. (5)
symmetry in symptoms severe lower limb involvement frequent falls severe cognitive dysfunction other unexpected movement disorder e.g. tics, chorea
Vascular Parkinsonism predominantly affects upper/lower limbs. Rest tremor is common/uncommon. Other vascular brain lesions may be present and it will show good/poor levodopa response.
- lower
- uncommon
- poor
Drug induced Parkinsonism is associated with drugs that block dopamine action & stops after drug has been withdrawn. It tends to be symmetrical/asymmetrical. It often has resting/postural tremor.
- symmetrical
- postural
