BACKGROUND
Overlap of cognitive and anxiety symptoms (i.e., difficulty concentrating, fatigue, restlessness) contributes to inconsistent, complicated assessment of generalized anxiety disorder (GAD) in persons with dementia.
METHODS
Anxious dementia patients completed a psychiatric interview, the Penn State Worry Questionnaire-Abbreviated, and the Rating for Anxiety in Dementia scale. Analyses to describe the 43 patients with and without GAD included the Wilcoxon Mann-Whitney two-sample test, Fisher's exact test. Predictors of GAD diagnosis were identified using logistic regression.
RESULTS
Those with GAD were more likely to be male, have less severe dementia and endorsed more worry, and anxiety compared to patients without GAD. Gender, muscle tension and fatigue differentiated those with GAD from those without GAD.
CONCLUSIONS
Although this study is limited by a small sample, it describes clinical characteristics of GAD in dementia, highlighting the importance of muscle tension and fatigue in recognizing GAD in persons with dementia.
