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.
One clue that epilepsy is not involved in what turn out to be PNES seizures is that anti-seizure medications fail to stop the symptoms, says Brandt, senior author of the study published online in the journal Seizure. That, he says, suggests that nothing is wrong with electrical activity in the patientsâ brains.
