Insomnia and mental disorders are linked. But exactly how is still a mystery

Insomnia and Mental Disorders: A Complex Relationship

What is Insomnia?

Insomnia is a common sleep disorder that affects approximately 12-15% of Australian adults at any given time. People with insomnia experience frequent and ongoing difficulties in falling asleep, staying asleep, or returning to sleep after waking up early. Insomnia not only affects the quality of sleep but also impairs daily functioning.

Is Insomnia a Mental Disorder?

Insomnia is not a mental disorder in the same way that depression, anxiety, or other mental health conditions are. However, it is closely linked to a wide range of mental disorders, including depression, anxiety, bipolar disorder, post-traumatic stress disorder, and substance-related disorders. In fact, around half of all people diagnosed with insomnia also have an associated mental disorder.

The Relationship Between Insomnia and Mental Disorders

The relationship between insomnia and mental disorders is complex and bidirectional. It’s not just a case of which comes first, the insomnia or the mental disorder. Instead, the two conditions are intertwined, with each influencing the other.

Shared Genetic Risk

One theory is that some people may have a shared genetic risk for insomnia and mental disorders. This means that certain genetic predispositions may increase the likelihood of developing both conditions.

Shared Neurobiological Response

Another theory is that the brain’s response to sleep loss may be connected to how it regulates cognition, emotion, and reward. Disturbances in these brain functions are implicated in a range of mental disorders, including insomnia.

Inflammation and Immune System Dysfunction

Some research suggests that inflammation and immune system dysfunction may underlie both insomnia and mental disorders.

Which Comes First?

The exact timing of when insomnia and mental disorders develop is unclear. Some research suggests that insomnia can occur before someone develops a mental disorder, while other studies indicate that mental disorders can precede insomnia.

Treating Insomnia and Mental Disorders

Cognitive behavioral therapy for insomnia (CBTi) is a type of talking therapy that aims to change unhelpful thoughts, feelings, emotions, and behaviors that contribute to insomnia. CBTi has been shown to be effective in treating insomnia and mental disorders, including depression, substance use, and post-traumatic stress disorder.

Filling the Gaps

Despite the complex relationship between insomnia and mental disorders, there are still many gaps in our understanding of the condition. Research is needed to better understand the causes, consequences, and treatment options for insomnia and mental disorders.

Conclusion

Insomnia and mental disorders are closely linked, but the exact nature of this relationship is still unclear. Further research is needed to fill the gaps in our understanding of the condition and to develop effective treatment options.
