A rare case of tongue biting during sleep in childhood.

UNLABELLED: Bleeding tongue-biting episodes during sleep are a rare and alarming situation that can negatively impact the child's and parents' sleep, affecting their quality of life. Although highly suggestive of epilepsy, a differential diagnosis should be made with sleep-related movement disorders such as bruxism, hypnic myoclonus, facio-mandibular myoclonus, and geniospasm when this hypothesis is excluded. The clinical history, electroencephalogram, and video-polysomnography are essential for diagnostic assessment. Treatment with clonazepam can be necessary in the presence of frequent tongue biting that causes severe injuries and sleep disturbance. This study reports the challenging case of managing and diagnosing a 2-year-old boy with recurrent tongue biting during sleep since he was 12 months old, causing bleeding lacerations, frequent awakenings, and significant sleep impairment with daytime consequences for him and his family.
