How Is Insomnia Diagnosed?

Initial Screening & Sleep History
If you suspect you may have insomnia, the first step is to reach out to a Resolve Sleep Health specialist for a comprehensive evaluation. Our team will conduct an initial assessment that reviews your sleep patterns, symptoms, lifestyle, and medical history.

Rule Out Other Conditions
As insomnia is often linked to medical, psychological, or environmental factors, our care team will evaluate for any underlying issues such as anxiety, depression, chronic pain, or sleep apnea. If sleep apnea is suspected, a Home Sleep Apnea Test may be recommended to inform the best treatment plan.

Diagnosis & Treatment Planning
Based on your results, you may be recommended to start Cognitive Behavioral Therapy for Insomnia (CBT-I) treatment. CBT-I is often combined with lifestyle modifications. In some cases, short-term medication may be prescribed to support your recovery.
