OBJECTIVES To evaluate the reliability of home respiratory polygraphy for the diagnosis of sleep apnea-hypopnea syndrome (SAHS) and to compare the cost of this technique with that of nighttime polysomnography performed in a sleep laboratory. PATIENTS AND METHODS This was a prospective study of a random sample of patients with clinically suspected SAHS in which the participants who underwent b...

OBJECTIVE To determine the accuracy of snoring and apnea analysis by SNAP (SNAP Laboratories; Glenview, IL), a technology that uses snoring recorded by a home microphone system and nasal airflow, to diagnose obstructive sleep apnea (OSA) as well as determine its severity. METHODS For all patients who had undergone a prior SNAP study and were referred to the Sleep Disorders Center of Lifespan ...

BACKGROUND Epilepsy patients commonly suffer from sleep disturbances, and these can exacerbate memory dysfunction and seizures. Sleep can be affected by seizures, independent sleep disorders, or anticonvulsant drugs. Levetiracetam is a novel anticonvulsant effective for the treatment of partial seizures. We studied the effects of levetiracetam (LEV) on sleep using polysomnography in normal subj...

OBJECTIVES Bipolar disorder is an illness characterized by sleep and circadian disturbance, and monitoring sleep in this population may signal an impending mood change. Actigraphy is an important clinical and research tool for examining sleep, but has not yet been systematically compared to polysomnography or sleep diary in bipolar disorder. The present study compares actigraphy, polysomnograph...
