Abstract

Background: Preliminary evidence suggests that demented patients may experience beneficial effects of light therapy. The authors tested whether bright light therapy (BLT) is capable of improving cognitive functions in patients with Alzheimer-type dementia (AD) or vascular dementia (VD). Methods: Twenty-three patients with AD or VD were randomly assigned to either evening BLT or dim light therapy (DLT). Effects of light therapy on cognitive functions were assessed before and after light therapy using Mini-Mental State Examination (MUSE) scores. Body temperature rhythm (BTR) was additionally recorded pre- and posttreatment. Results: Irrespective of their diagnosis, patients treated with BLT (p =.0012) but not with DLT (p =.73) showed a statistically significant increase in MMSE total scores after light therapy. Evening BLT simultaneously induced a significant phase delay of 56 min on BTR (p =.025). Conclusions: Our preliminary results suggest that shortterm evening BLT may exert beneficial effects on cognitive functioning in patients with dementia. 2001 Society of Biological Psychiatry.
