English to Bulgarian Medical Medical (general) SLEEP DISORDERS

Disturbed sleep is among the most frequent health complaints physicians encounter. More than one-half of adults in the United States experience at least intermittent sleep disturbances. For most, it is an occasional night of poor sleep and/or daytime sleepiness. However, at least 15 to 20% of adults report chronic sleep disturbance or misalignment of circadian timing, which can lead to serious impairment of daytime functioning. In addition, such problems may contribute to or exacerbate medical or psychiatric conditions.
