Parkinson's disease is a progressive neurodegenerative disorder. Symptoms evolve over years to decades. For paraquat litigation, the stage of disease at the time of claim affects both medical reality and case value.
Stage 1 — early unilateral symptoms
Tremor, rigidity, or bradykinesia (slowness of movement) on one side of the body. Posture and balance are normal. Many people in Stage 1 still work and live independently. Diagnosis at this stage is often delayed because symptoms can be subtle.
Stage 2 — bilateral involvement
Symptoms become bilateral. Walking and balance are affected but the person remains independent. Daily activities take longer. Most people are diagnosed during Stage 1 or Stage 2.
Stage 3 — significant balance impairment
Postural instability becomes prominent. Falls become more frequent. Independence in daily activities is partially affected. Most people in Stage 3 can still live at home with modifications.
Stage 4 — significant disability
Severe symptoms. The person can stand and walk only with assistance. Cannot live alone. Daily care assistance is required.
Stage 5 — wheelchair or bedridden
The person is wheelchair-bound or bedridden. Around-the-clock nursing care is required. Cognitive symptoms may dominate.
How staging affects case value
More advanced disease typically supports higher economic damages (lost income, future medical care) and higher non-economic damages (pain, suffering, loss of consortium). However, younger plaintiffs with earlier-stage disease often score well in points-based settlement matrices because of longer expected disability.
