The Brazilian Sleep Association brought together specialists in sleep medicine, in order
to develop new guidelines on the diagnosis and treatment of insomnias. The following
subjects were discussed: concepts, clinical and psychosocial evaluations, recommendations
for polysomnography, pharmacological treatment, behavioral and cognitive therapy,
comorbidities and insomnia in children. Four levels of evidence were envisaged: standard,
recommended, optional and not recommended. For diagnosing of insomnia, psychosocial
and polysomnographic investigation were recommended. For non-pharmacological
treatment, cognitive behavioral treatment was considered to be standard, while for
pharmacological treatment, zolpidem was indicated as the standard drug because of its
hypnotic profile, while zopiclone, trazodone and doxepin were recommended.
Key words: insomnia, diagnosis of insomnia, treatment of insomnia, cognitive behavioral
therapy.
