Post-traumatic complaint of somnolence was associated with variable degrees of impaired daytime functioning in more than 98% of patients. Patients who were in a coma for 24 hours, who had a head fracture, or who had immediate neurosurgical i nterventions were likely to have scores > 16 points on the Epworth Sleepiness Scale (ESS) and = 5 minutes on the MSLT. Pain at night was an important factor in nocturnal sleep disruption and daytime sleepiness. Sleep-disordered breathing was a common finding and was the only finding in whiplash patients with daytime sleepiness. Extensive evaluation of pretrauma behavior supported the conclusion that the onset of symptomatic sleep-disordered breathing was associated with the trauma. The patients who showed a "compulsive presleep behavior" were severely impaired in performing their daily activities. A systematic approach is required when dealing with patients complaining of hypersomnia following a head-neck trauma. |
