191
Causes of parkinsonism?
Idiopathic-dementia with Lewy bodies Drug induced (dopamine antagonists) Vascular parkinsonism Parkinson's plus syndromes (multiple system atrophy, progressive supranuclear palsy/ corticobasal degeneration)
192
What is the early medical treatment of Parkinson's
Levodopa, MAO-B inhibitors- selegiline, rasagiline, safinamide COMT inhibitors- entacapone Dopamine agonists- ropinirole, pramipexole, rotigotine
193
What is the late treatment of Parkinson's
MAO-B inhbitors, COMT inhibitors, slow release levodopa (to prolong levodopa half life), add oral dopamine agonist, continuous infusion of apomorphine and duodopa functional neurosurgery
194
What are later drug-induced complications in Parkinson's
motor fluctuation- as levodopa wears off, dyskinesias- involuntary movements (levodopa), hallucinations, impulse control
