OBJECTIVES Psychogenic nonepileptic seizures (PNES) are frequently encountered in epilepsy monitoring units (EMU) and can result in significant long-term disability. We reviewed our experience with veterans undergoing seizure evaluation in the EMU to determine the time delay to diagnosis of PNES, the frequency of PNES, and cumulative antiepileptic drug(More)
OBJECTIVE To identify brain regions generating tics in patients with Tourette syndrome using sleep as a baseline. METHODS We used [15O]H2O PET to study nine patients with Tourette syndrome and nine matched control subjects. For patients, conditions included tic release states and sleep stage 2; and for control subjects, rest states and sleep stage 2. (More)
The physiology of control and suppression of natural urges is not well understood. We used [(15)O]H(2)O positron-emission tomography imaging to identify neural circuits involved in suppression of spontaneous blinking as a model of normal urges. Suppression of blinking was associated with prominent activation of bilateral insular-claustrum regions, right(More)
Background. Fatigue is the most common symptom in people with multiple sclerosis (MS). Poor sleep also occurs in this population. Objective. The objective of this study was to determine the relationship between fatigue and sleep quality in people with MS and cognitive impairment. Method. This cross-sectional study assessed relationships among fatigue,(More)
OBJECTIVES To evaluate the feasibility and safety of head-neck cooling in conscious normal volunteers (10) and patients with medically refractory epilepsy (5) without causing shivering. PATIENTS AND METHODS We used a non-invasive head-neck cooling system (CoolSystems Inc., Lincoln, CA, USA). The tympanic temperature (TT) and intestinal temperature (IT)(More)
Problems with sleep and cognitive impairment are common among people with multiple sclerosis (MS). The present study examined the relationship between self-reported sleep and both objective and perceived cognitive impairment in MS. Data were obtained from the baseline assessment of a multi-centre intervention trial (NCT00841321). Participants were 121(More)
PURPOSE Traumatic brain injury (TBI) is an important cause of epilepsy and has also been associated with psychogenic nonepileptic seizures (PNES). We designed a brief questionnaire assessing patient beliefs regarding TBI as the cause of their seizures (Patient Seizure Etiology Questionnaire; PSEQ). This study reports content validity for the PSEQ. METHODS(More)
OBJECTIVES The long-term outcome of patients with psychogenic nonepileptic seizures (PNES) is of importance given the disabling symptoms and tendency to affect patients early in their productive years. Health care utilization (HCU) is an important outcome measure reflecting overall health status and costs. There is little information regarding long-term HCU(More)
OBJECTIVES : The objectives of this study were to describe sleep quality and evaluate the association of sleep quality with delirium onset among patients enrolled in hospice. DESIGN : The study utilized secondary data from a prospective, observational, longitudinal study. SETTING : Veterans enrolled in hospice were recruited from the Portland Veterans(More)
Mice are one of the most commonly used animal models of alcoholism, and extensive genetic and behavioral data related to alcohol consumption and its consequences in different strains are available. However, only recently have researchers begun to combine magnetic resonance imaging (MRI) technology with other experimental strategies to study the effects of(More)
