Sleep disturbances in patients with psychogenic non-epileptic seizures: Is it all subjective? A prospective pilot study of sleep-wake patterns

Poor sleep is a frequent complaint of patients with psychogenic non-epileptic seizures (PNES). Our group has recently reported that PNES subjects more frequently complained of poor sleep patterns relative to those with epilepsy [1], however the study was limited by use of a single item from the Beck Depression Inventory to assess changes in sleep patterns. Currently, little is known about the pattern and cause of sleep problems in PNES. One prior study investigated sleep architecture of 8 PNES and 10 epilepsy subjects using EEG recordings in the Epilepsy Monitoring Unit (EMU) [2].
