Q

Pt has Parkinsons: cogwheel rigidity, resting tremor, small writing, orthostasis, intact congnition.
He’s 55 yo, what is 1st line treatment?
Over 60?

A

Anticholinergics: benztropine or hydroxyzine

>60: Amantadine = increase dopamine release (too many SE with old people on anticholinergics)*

Q

Pt with severe parkinsons starting to have symptoms of pyschosis. Why is this? What should you do?

Q

Medications for parkinsons

Goal is to increase dopamine

A
  1. Anticholinergic if <60; benztropine/hydroxyzine
    OR Amantidine >60
  2. Severe symptoms;
    Levo or Cardiodopa (more efficacious, can see on-off phenomenon)
    or
    Dopamine antagonist (pramipexole, ropinerole, cabergoline)
    Next
    COMT inhibitors: tolcapone/entacapone to prevent metabolism of dopamine
    MAO inhibitors: Selegiline or rasagiline
