The Long List of Parkinson's Disease Symptoms, Sorted by Stage

The journey through Parkinson’s disease varies from person to person, but most people experience a mix of motor (movement-related) and non-motor symptoms that evolve over time. Below is a comprehensive list of 40 symptoms, sorted roughly by early, mid, and advanced stages. If you’re worried about any of these signs, you might consider doing a free, online symptom check using the doctor approved Ubie Symptom Checker. Always speak to a doctor about anything that could be life-threatening or seriously affecting your daily life.

Early-Stage Symptoms (1–10)

In the beginning, symptoms are often subtle and may be mistaken for normal aging or stress.

1. Resting tremor (“pill-rolling” finger tremor)
2. Slight muscle stiffness (rigidity) in one limb
3. Slowness of movement (bradykinesia)
4. Small, cramped handwriting (micrographia)
5. Reduced facial expression (mask-like face)
6. Decreased arm swing on one side when walking
7. Diminished sense of smell (anosmia)
8. Mild sleep disturbances (REM sleep behavior disorder)
9. Occasional constipation or slow digestion
10. Low mood, mild depression or anxiety

Mid-Stage Symptoms (11–25)

As the disease progresses, symptoms typically become more pronounced and begin to affect daily activities.

11. Generalized muscle rigidity, affecting both sides
12. Noticeable shuffling gait
13. Mild postural instability—trouble keeping balance
14. “Freezing” episodes when initiating steps
15. Stooped or forward-leaning posture
16. Soft, monotone voice (hypophonia)
17. Difficulty swallowing (dysphagia)
18. Dribbling saliva or increased drooling
19. Urinary urgency or increased frequency
20. Erectile dysfunction or reduced libido
21. Dizziness upon standing (orthostatic hypotension)
22. Daytime fatigue or excessive sleepiness
23. Aches, cramps, or unexplained limb pain
24. Sleep fragmentation—waking repeatedly at night
25. Mental fog, difficulty concentrating

Advanced-Stage Symptoms (26–40)

In later stages, both motor and non-motor symptoms can severely affect independence and quality of life.

26. Marked loss of balance, frequent falls
27. Severe rigidity, “cogwheel” movements
28. Pronounced freezing of gait, even when walking aid is used
29. Worsening speech issues—slurred or barely audible speech
30. Swallowing becomes dangerous—risk of choking or aspiration
31. Uncontrolled, involuntary movements (dyskinesias), often from long-term medication use
32. Cognitive decline—memory lapses, slowed thinking
33. Hallucinations or vivid dreams
34. Psychosis—delusions or paranoia
35. Complete urinary incontinence
36. Significant weight loss or difficulty maintaining weight
37. Severe depression or apathy interfering with motivation
38. Autonomic dysfunction—excessive sweating or temperature regulation issues
39. Breathing difficulties—shallow or uncoordinated breaths
40. Total dependence for activities of daily living (eating, dressing, bathing)
