Childhood sleep terrors, which often send children into screaming fits, may be inherited.In a new study researchers looked at 390 sets of twins. They found identical twins were more likely to experience night terrors than fraternal twins.

The researchers say environmental factors could also play a role in sleep terrors because the twins were raised together in similar settings.

The scientists say that while the findings show genetic factors contribute to sleep terrors, they have not yet identified any specific genes behind the phenomenon.
