Abstract
An unusual case of sundown syndrome is here reported, in which a bilingual
patient would involuntarily change languages at sunset. Numerous theories
have been advanced in attempting to account for sundowning. Cameron has
suggested that nocturnal delirium was based on an inability to maintain a
spatial image without the assistance of repeated visualization. Kral and
Wolanin and Phillips have argued for a more psychogenic account, by stating
that psychosocial stressors may, in concert with impaired cognitive
functioning, account for sundowning. The present case concerns a 42-year-old
white male who in January 1989 suffered a closed head injury. A thorough
personal history as well as a detailed examination of the patient's daily
activities allowed us to account for the unusual manner in which the
sundowning manifested itself. The uniqueness of this case allows us to
underscore both the psychological as well as environmental and neurological
factors involved in sundowning. Thus, we have as a consequence been able to
synthesize the seemingly disparate accounts of both Cameron and more recent
published literature.
