Abstract Objective Cognitive stimulation therapy (CST) is a well-supported nonpharmacological intervention, found to improve or maintain global cognition, daily functioning, and quality of life with persons with dementia. There are fewer studies assessing the effect of CST on neuropsychiatric symptoms; however, pilot studies have identified improvement in depression and anxiety in studies of persons with Alzheimer’s disease. The purpose of this program evaluation was to evaluate the impact of CST on neuropsychiatric symptoms and everyday functioning is a veteran sample. Method Twenty-six male veterans diagnosed with cognitive disorder (84.6% dementia, 15.4% mild cognitive impairment) completed a 7-week CST program. The sample was diverse (46.2% White/Caucasian, 42.3% Hispanic/Latino, 7.7% Black/African American; 38.5% bilingual). Most frequent etiologies included mixed (26.8%), Alzheimer’s (23.1%), and vascular (19.2%). Ages ranged from 43–86 (M = 74.5; SD = 7.6). Pre-group/post-group assessment included Geriatric Depression Scale-Short Form (GDS-SF), Geriatric Anxiety Inventory (GAI), Neuropsychiatric Inventory (NPI-informant), Everyday Cognitive (ECOG), and Texas Functional Living Scale (TFLS). Analyses included paired-samples t-test and Wilcoxon signed-rank test. Results Post-group GAI scores were significantly lower (Median = 1) than pre-group scores (Median = 3), z = −2.574, p = 0.01, r = −0.515. There were no significant declines or improvements across other measures of neuropsychiatric symptoms. Measures of IADLs/everyday functioning also remained stable. Conclusions Consistent with prior studies, CST was effective in reducing anxiety symptoms of veterans with cognitive disorders. While measures of everyday functioning did not improve, performance and informant-report remained stable. CST presents a unique opportunity to impact both cognition and neuropsychiatric symptoms that may cause significant distress in veterans with dementia and their caregivers.
