Diagnostic tools to identify a sleep disorder
What are some diagnostic tools that can objectively identify a sleep disorder?
In addition to the history and physical examination, sleep testing is helpful for the evaluation of sleep disorders.
This may include an overnight polysomnography (PSG), ambulatory home study (used in adults), actigraphy, mean sleep latency test (MSLT), sleep logs, and sleep questionnaires.
The International Classification of Sleep Disorders-Third edition (ICSD-3) is a diagnostic and coding manual that provides a thorough review of sleep disorders that is available to all practitioners.
The manual includes essential features, diagnostic criteria, predisposing factors, pathophysiology, clinical findings, and differential diagnoses.
