Insomnia disorder is a sleep disorder that involves difficulty falling asleep, staying asleep, or both. People with insomnia often report feeling tired, irritable, and unable to concentrate during the day.
Insomnia disorder can be classified into different types based on the cause and associated factors.
- Primary insomnia: When insomnia is not related to any other medical, psychiatric, or sleep disorder, it is called primary insomnia.
- Comorbid insomnia: When insomnia is related to other conditions such as mental health disorders (e.g., depression, anxiety, post-traumatic stress disorder) or medical conditions (e.g., chronic pain, asthma, heart disease), it is called comorbid insomnia.
- Sleep onset insomnia: This type of insomnia involves difficulty falling asleep at the beginning of the night.
- Sleep maintenance insomnia: This type of insomnia involves difficulty staying asleep, resulting in frequent awakenings throughout the night.
- Early morning awakening insomnia: This type of insomnia involves waking up too early in the morning and having difficulty falling back asleep.
Difficulty falling or staying asleep, has become increasingly common in recent years. With the rise of digital technology and the 24/7 nature of modern life, more and more people are struggling to get the rest they need. This lack of sleep can have serious physical health effects, including a weakened immune system, increased risk of chronic diseases such as diabetes and heart disease, and even decreased life expectancy. Additionally, insomnia can lead to mental health issues such as anxiety and depression, as well as impaired cognitive function and decreased productivity. As such, it is important for individuals to prioritize sleep and seek treatment if they are struggling with insomnia.
The diagnosis and treatment of insomnia disorder may involve a thorough evaluation of medical and psychiatric history, as well as sleep habits and patterns. Treatment may include behavioral interventions, such as cognitive behavioral therapy for insomnia (CBT-I), medication, or a combination of both.
