Insomnia is a clinical diagnosis. Diagnostic studies are indicated principally for the clarification of comorbid disorders. Measures that may be considered include the following:

  • Studies for hypoxemia

  • Polysomnography and daytime multiple sleep latency testing (MSLT)

  • Actigraphy

  • Sleep diary

  • Genetic testing (eg, for FFI)

  • Brain imaging (eg, to assist in the diagnosis of FFI [2] )

See Workup for more detail.
