a
Matis dementia rating supplied.
b
Indicates established criteria were used to define PD hallucinations.
FDG-PET, fluorodeoxyglucose positron emission tomography; MMSE, mini-mental state examination; PDVH, Parkinson’s disease with visual hallucinations; SPECT, single photon emission computed tomography; UPDRS, unified parkinson's disease rating scale score (part III, motor); VBM, voxel-based morphometry.
No significant differences between groups for any of these comparisons.
