OBJECTIVE: To investigate the effect of ramelteon on sleep and daytime
functioning among individuals with traumatic brain injury (TBI).
DESIGN: A double blind placebo controlled study with a cross-over design.
SETTING: A research facility attached to an acute rehabilitation hospital.
PARTICIPANTS: Individuals with TBI (N=13) complaining of sleep difficulties with
a Pittsburgh Sleep Quality Index score greater than five.
INTERVENTIONS: A nightly dosage of ramelteon (8mg) was given over a period of
three weeks.
MAIN OUTCOME MEASURES: An actigraph and daily sleep log were used to measure
sleep/wake patterns along with a daily sleep log. Daytime functioning was
measured after three weeks of treatment using a computer-administrated
neuropsychological test battery (CNS Vital Signs software) in conjunction with
subjective questionnaires measuring mood, daytime sleepiness, and fatigue.
RESULTS: A significant increase in objectively measured total sleep time and a
small increase in sleep latency were observed after three weeks of treatment
compared with placebo. Treatment also showed a significant increase in
standardized neuropsychological test scores, with a particular improvement on an
index of executive functioning.
CONCLUSIONS: Preliminary evidence for the effectiveness of 8mg of ramelteon taken
nightly over a three week period was found in the treatment of sleep difficulties
among individuals with TBI. Improvements in total sleep time and some aspects of
cognitive functioning are discussed.
