Folstein's Mini Mental State Exam, a test assessing the capacity to perform novel and/or repetitive motor tasks (Behavioral Dyscontrol Scale) and a brief measure of working memory were used in a sample of 50 male Veterans Affairs geriatric clinic patients who ranged in age from 63 to 105 (mean, 80.1). The purpose of this study was to attempt to predict the patients' capacity to regulate their behavior independently. We hypothesized that frontal lobe disorders often impair a patient's ability to function autonomously and that the Behavioral Dyscontrol Scale, a measure of frontal lobe impairment, would best predict the capacity for independent regulation of purposeful behavior. Therefore, we examined the relationship of the Behavioral Dyscontrol Scale with spouses' and caregivers' ratings of patients' independent living skills, and with behaviors that interfere with independent functioning. The results of hierarchical regression analyses indicated that the Behavioral Dyscontrol Scale was the only predictor of functional autonomy and was the best predictor of both impulsivity and apathy among geriatric patients. The Behavioral Dyscontrol Scale appears to assess a different functional domain than do the MMSE and similar measures, which rely heavily on the evaluation of orientation and gross cognitive status.
