Which condition involves difficulty falling or staying asleep unrelated to other issues?

Primary insomnia is characterized by sleep difficulties that are not attributable to other underlying medical or psychological conditions. This condition is often defined by individuals experiencing difficulty falling asleep or staying asleep, alongside complaints of sleep quality and quantity, all while not being influenced by external factors such as stress or other mental health disorders.

In contrast, other forms of insomnia, such as rebound insomnia, occur as a result of discontinuing sleep medication, while paradoxical insomnia refers to a situation where the individual believes they are getting little to no sleep, but objective measurements indicate otherwise. Chronic insomnia is defined as having sleep disturbances that persist for a longer duration, typically more than three months, often linked to underlying health issues. Therefore, primary insomnia stands out as it is identified by these sleep issues occurring independently of any other medical or psychological factors.
