Researchers uncover different types of insomnia, which will help make treatments more targeted

Scientists have identified five different types of insomnia, a finding they say paves the way for more targeted treatments and therapies for those who experience the condition.

The subtypes are not based on sleep complaints, such as difficulty falling asleep or early morning awakening, but on differences between personality traits, responses to treatment, life history and risk of depression.
