Impairment in at least two of the four typically involved cognitive domains (impaired and often fluctuating attention; dysexecutive changes; impaired visuospatial abilities; and impaired free recall that improves with cueing) must be documented without prominent language dysfunction, as demonstrated by clinical and cognitive examination. The authors take into account that the main behavioral or neuropsychiatric symptoms seen in PD-D include visual hallucinations, delusions, apathy, depressed mood, anxiety, and excessive daytime sleepiness. These features are frequent in PD-D, but their presence is not invariable. The presence of at least one symptom from this set supports, but is not required for, the diagnosis of PD-D. Further details on diagnostic criteria for PD-D can be found in Emre et al. (2007a) and the proposed neuropsychological assessment methods to be carried out with these patients have been published in Dubois et al. (2007), from the same workgroup.
