Scenаriо 6 A 4-yeаr-оld mаle was brоught by his mother to the sleep clinic for evaluation and management of bouts of screaming that occur during the night. The patient’s mother noted that the patient has “always been a restless sleeper” since infancy and has struggled with nighttime awakenings and independent sleep. However, over the past 6 months, the patient started disruptive nighttime screaming. During a typical event, he would suddenly start screaming loudly, typically a few hours after sleep onset. During these episodes, he would sweat and breathe quickly, and as the patient’s mother tried to calm him down, she could feel his heart racing. These episodes lasted a few minutes but sometimes as long as 30 minutes. There was no history of stereotyped or rhythmic movements. When asked about the episodes, the patient stated that he did not know what his mother was talking about and claimed he did not wake up at night. He denied vivid dreams or waking up in places other than his room and did not remember having awakened feeling inexplicably injured. During these episodes, the patient’s mother was unable to console him. The family has not found any intervention that shortened the duration of the episodes. Even when not having these episodes, the patient has frequent arousals where he tosses, turns, and might vocalize but falls back to sleep shortly. The patient snores during sleep and often falls asleep outside of nap times. Daytime and nighttime enuresis were present, but the parents are trying to potty-train the patient.
