Q

management for parkinson’s

A
  • at diagnosis if they have significant impact of motor symptoms of ADLs then treat with co-careldopa
  • if they don’t have significant impact of motor symptoms of ADLs then treat with a choice of either dopamine agonists, co-careldopa or MAO-BI
  • can also give anti-muscarinics which help with tremor and rigidity
  • can also give amantidine which increases dopamine release and prevents reuptake in the synapses

assume capacity

maximise decision making capacity - support given to reach decision

freedom to make seemingly unwise decisions
