FIGURE 2.

Percentage of participants who report having “severe” symptoms of each NPI‐Q item at initial visit stratified by CDR Stage. Figure 2 shows participants who responded having “severe” neuropsychiatric symptoms in each NPI‐Q item by AD stages at initial visit (i.e., MCI due to AD, mild, moderate, and severe AD dementia). The y axis shows each of the NPI‐Q items. The x axis is the percent of participants who responded “severe” to each of the item in the NPI‐Q. Higher NPI‐Q score indicates more impaired AD. AD, Alzheimer's disease; CDR, Clinical Dementia Rating Scale; MCI, mild cognitive impairment; NPI‐Q, Neuropsychiatric Symptoms Questionnaire
