Formatted Abstract/Summary
Background: Although anxiety is thought to be highly prevalent among people with Alzheimer's disease and related disorders, more work is required to define the nature and significance of anxiety symptoms in this context. Accordingly, we investigated generalized anxiety in memory clinic attendees using a newly developed scale. Methods: We recruited a consecutive series of 100 community-residing memory clinic attendees and their caregivers at an academic medical centre. Generalized anxiety was measured on the Geriatric Anxiety Inventory (GAI), a 20-item self-report scale. In addition, we rated the patients on a standardized battery of measures. We compared our GAI findings with results from normal volunteers and psychogeriatric patients.Results: There were 58 female and 42 male patients with a mean age of 76.9 years (SD 7.8; range 61-95). Over two thirds had dementia (47% AD; 3% VaD; 16% mixed), with an additional 15% CIND or MCI. Mean sMMSE score was 23.2 (SD 5.1; range 5-30) and mean IQCODE score was 4.2 (SD 0.6; range 3-5). Mean GAI score was 4.97 (SD 5.32; range 0-20) with Cronbach's alpha 0.92. In comparison, a separate population-based cohort of 205 women aged 65+ years (mean 74.4; SD 5.5; range 65-86) had a mean GAI score of 2.32 (SD 4.03; range 0-19); a separate clinical sample of 46 male and female psychogeriatric patients (mean age 78.8 years; SD 6.7; range 66-94) had a mean GAI score of 5.22 (SD 5.83). As expected, GAI score was correlated with NPI anxiety severity (r = 0.31; p = 0.0037), NPI anxiety distress (r = 0.32; p = 0.0031) and GDS (r = 0.62; p = 0.000). GAI was also correlated with Barthel score (r = -0.2837; p = 0.0118), and leisure activities score (r = - 0.32; p = 0.0050). Conclusions: The mean levels of clinic attendees' self-reported anxiety were much higher than those reported by normal older volunteers but somewhat lower than those reported by psychogeriatric patients. Higher levels of anxiety were reported by patients with higher levels of physical dependency whereas lower levels of anxiety were reported by patients with greater involvement in leisure activities.
