[Light therapy in 3 children with winter depression].

In three children, boys of 5 and 13 years old and a girl aged 10, seasonal affective disorder was diagnosed based on mood changes (listlessness, fears) and increased sleepiness in the winter season. They were treated successfully with light therapy (5 consecutive days 30 min 10,000 lux of full spectrum light without ultraviolet). In two patients the disorder recurred in the fall/winter the year(s) thereafter, and they were again treated successfully.
