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.
During a seizure, there is abnormal and excessive electrical activity in the brain. This can cause changes in awareness, behavior, and/or abnormal movements. This activity usually lasts only a few seconds to minutes. Epilepsy refers to a condition in which a person has a risk of recurring epileptic seizures. Not everyone who has had a seizure has epilepsy. Nonepileptic seizures can be caused by other conditions such as low blood sugar, a fainting spell, or an anxiety attack. SEIZURE SYMPTOMS.
