Abstract

The efficacy of fluvoxamine on cognitive functioning and behavioral changes was evaluated in a double-blind, placebo-controlled study of 46 elderly demented patients. The patients had a DSM-III diagnosis of primary degenerative dementia or multi-infarct dementia and were aged greater than or equal to 65 years. Twenty-two patients were given 150 mg fluvoxamine per day and 24 received placebo tablets; 14 and 15 patients, respectively, completed 6 weeks of treatment. Within treatments, there were no significant changes in median scores on neuropsychological tests (picture recall and recognition, trail making and finger tapping) or the GBS scale scores (degrees of dementia) or GBS subscale score (clinical profiles, including symptoms common in dementia, motor, emotional and intellectual functioning). Between treatments, the median changes in psychometric test scores did not differ significantly. However, within and between treatments, there were trends favoring fluvoxamine on symptoms common in dementia (confusion, irritability, anxiety, fear-panic, mood level and restlessness). In conclusion, the study does not support the hypothesis that fluvoxamine improves cognitive functioning or behavioral changes in elderly dementia patients.
