During aerobic exercise the performance of the heart is based on heart rate, the amount of blood pumped per beat (stroke volume), and heart contractility, or the forcefulness of each heart contraction. Combined, these variables increase blood flow and oxygen supply to meet the demands of the exercising muscles.
Non-epileptic seizures are paroxysmal events that mimic an epileptic seizure but do not involve abnormal, rhythmic discharges of cortical neurons.[1] They are caused by either physiological or psychological conditions. The latter is discussed more fully in psychogenic non-epileptic seizures.
Psychogenic nonepileptic seizures are episodes of movement, sensation, or behaviors that are similar to epileptic seizures but do not have a neurologic origin; rather, they are somatic manifestations of psychologic distress. Patients with psychogenic nonepileptic seizures frequently are misdiagnosed and treated for epilepsy. Video-electroencephalography monitoring is preferred for diagnosis. From 5 to 10 percent of outpatient epilepsy patients and 20 to 40 percent of inpatient epilepsy patients have psychogenic nonepileptic seizures.
