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.
A non-epileptic seizure, or non-epileptic event, is a seizure that isn't caused by epilepsy but looks the same. These may be caused by a change or difference in electrical activity in the brain, but not an electrical disruption of the type that triggers an epileptic seizure. There are two types of non-epileptic seizures, called psychogenic and physiologic. A psychogenic non-epileptic seizure can be brought on by some sort of emotional stressor or trauma. It's a legitimate seizure and should be treated that way, but it is not caused by a problem in the brain.
