Night terrors strike children, usually between the ages of 3 years and 8 years. They rarely occur in older children, adolescents and adults. In both adults and children, night terrors may be caused by unsettled psychological conflicts, upsetting events or tiredness.
Night terrors can often be mistaken for confusional arousal. Sleep terrors begin between ages 3 and 12 years and then usually dissipate during adolescence. In adults, they most commonly occur between the ages of 20 to 30.
