Pathway Overview
16 steps
Algorithm Steps
16 total
01Start 02Action Assess Motor Symptoms
Determine symptom severity and impact
- Bradykinesia (required for diagnosis)
- Rigidity
- Resting tremor
- Postural instability (later feature)
- Functional impairment level
03Decision Functional Impairment?
Are symptoms affecting daily activities?
- Work performance
- Activities of daily living
- Quality of life
- Patient perception of disability
04Action No Immediate Treatment
If minimal symptoms
- Education about PD
- Exercise program (beneficial)
- Monitor for progression
- Reassess in 3-6 months
05Decision Select Initial Therapy
Consider patient factors
- Age (younger vs older)
- Symptom severity
- Cognitive status
- Motor fluctuation concerns
- Patient preference
06Action Levodopa (+ Carbidopa)
Most effective for motor symptoms
- Start: carbidopa/levodopa 25/100 TID
- Most efficacious (Level A)
- Earlier motor fluctuations risk
- Better for older patients, significant impairment
- Monitor: dyskinesias, wearing off
07Action Monitor Treatment Response
Titrate to effect
- Assess motor function improvement
- Watch for side effects
- Levodopa: titrate slowly over weeks
- DA: start low, titrate very slowly
- Follow up in 4-8 weeks
08Decision Adequate Response?
Evaluate motor control
09Action Add/Adjust Therapy
Combination approach
- Add levodopa if on DA/MAO-B alone
- Add COMT inhibitor (entacapone)
- Increase levodopa dose/frequency
- Add amantadine for dyskinesias
- Consider specialist referral
- Path rejoins step 07Shared downstream outcome
10Warning ⚠️ Motor Fluctuations
Common after years of treatment
- Wearing off (end-of-dose deterioration)
- On-off fluctuations
- Dyskinesias (peak-dose or diphasic)
- May need advanced therapies
11Action Manage Fluctuations
Optimization strategies
- Fractionate levodopa (smaller, more frequent)
- Add COMT inhibitor
- Extended-release formulations
- Amantadine for dyskinesias
- Consider DBS or pump therapy
12Action Consider Advanced Therapies
For refractory motor fluctuations
- Deep brain stimulation (DBS)
- Levodopa-carbidopa intestinal gel (Duopa)
- Apomorphine infusion/injection
- Refer to movement disorders specialist
13Outcome Ongoing Management
Long-term follow-up
- Regular neurology follow-up (q3-6 months)
- PT/OT/Speech therapy as needed
- Fall prevention
- Advance care planning discussions
- Path rejoins step 13Shared downstream outcome
14Action Address Non-Motor Symptoms
Comprehensive care
- Depression/anxiety: SSRIs, SNRIs
- Cognitive impairment: rivastigmine
- Constipation: fiber, laxatives
- Orthostatic hypotension: fludrocortisone
- Sleep disorders: melatonin, clonazepam
- Path rejoins step 13Shared downstream outcome
15Action Dopamine Agonist
Consider in younger patients
- Pramipexole, ropinirole, rotigotine patch
- Lower dyskinesia risk short-term
- More side effects (impulse control, sleepiness)
- Less effective than levodopa
- Younger patients (<65) may prefer
- Path rejoins step 07Shared downstream outcome
16Action MAO-B Inhibitor
Mild benefit, well-tolerated
- Rasagiline 1 mg daily or selegiline
- Modest symptomatic benefit
- Generally well-tolerated
- May delay need for levodopa
- Can use as monotherapy in mild PD
- Path rejoins step 07Shared downstream outcome
- Path rejoins step 05Shared downstream outcome
