[Primary and secondary insomnias and sleep related breathing disturbances]

Insomnias and sleep-related breathing disturbances are a heterogeneous group of primary and secondary pathological conditions. Primary insomnias develop due to the hyperarousal condition and sleep preventing practices. Diagnosis of the secondary insomnia is always difficult because the presence of the temporarily association between the causative disease and sleep disorder needs to be confirmed. Along with the general principles of treatment for the primary and secondary insomnia, the specific treatment modalities exist. It could be the correction of the primary disease or special techniques for the separate form of insomnia. From the sleep-related breathing disturbances the most common and clinically important form is the obstructive sleep apnea syndrome. There are adult and pediatric forms of this disorder. Primary or secondary origin of these syndromes is discussed, but the most effective treatment by nasal continuous positive airway pressure (nCPAP) is nonspecific. This makes such doubt not important yet.
