Correct answer: C — Provide objective longitudinal measures of mobility and motor fluctuations to supplement

The best answer is “Provide objective longitudinal measures of mobility and motor fluctuations to supplement”. Wearables can quantify movement in daily life, but data must be interpreted alongside the clinical phenotype and what matters to the patient. “Diagnose Parkinson’s disease independently of examination” is a credible alternative elsewhere, but it fails the decisive discriminator in this case. “Determine levodopa dose automatically without clinician review” is a credible alternative elsewhere, but it fails the decisive discriminator in this case. “Replace assessment of cognition, hallucinations and falls” is a credible alternative elsewhere, but it fails the decisive discriminator in this case. “Prove that every reported off period is dopaminergic” is a credible alternative elsewhere, but it fails the decisive discriminator in this case.
