Cognition in Patients With a Clinical Diagnosis of Parkinson Disease and Scans Without Evidence of Dopaminergic Deficit (SWEDD): 2-Year Follow-Up

Conclusions: This study provides evidence that some individuals clinically diagnosed with idiopathic Parkinson disease but with SWEDD demonstrate early cognitive decline. The results also suggest that recently diagnosed patients with SWEDD may be at even greater risk for cognitive decline than patients with DaTscan-confirmed early-stage Parkinson disease. While patients with SWEDD likely represent a heterogeneous group of etiologies, our results highlight the need to monitor these patients’ cognitive function over time.
