A seizure is a condition produced by uncontrolled electrical impulses in the brain. In effect, the body may produce physical convulsion or uncontrolled and body movement. This may also be defined as synchronous neuronal brain activity. Seizure can be caused by several things. Some of which could be attributed to head injuries, brain tumors, lead poisoning, genetic and infectious disease, fever, multiple sclerosis, binaural beat brainwave entrainment, sleep deprivation, intoxication, metabolic disturbances and many others. The symptoms of seizures will depend on the type and the type of the seizure is dependent on the electrical impulses produced in the brain. There are two types of seizures, the generalized seizure in which the electrical impulses take place in the entire brain and the partial seizure. The partial seizure only takes place in certain or a particular part of the brain.
One type of seizure is generalized seizure. This type of seizure is produced by the entire brain and the symptom seizures are unconsciousness, convulsions, muscle rigidity, jerking movements and loss of muscle tone. A seizure goes through three stages, the early stage, middle stage and the end. Before a seizure starts, some patients claim to see an aura. An aura is a bright light that a patient sees before a seizure strikes. The vision of an aura could take place for just a second or in some cases the bright light appears a bit longer. Sometimes when an aura is not followed by any other symptoms, the doctors would usually refer to it as a partial seizure. The next stage is the middle stage; this is where the convulsion and jerking movements take place. At this stage the patient experiences convulsion, muscle rigidity and usually collapses and losses consciousness. In a generalized seizure the patient may have some injuries such as tongue biting. The last stage in a seizure is the end or the post-ictal stage. At this point, the patient may go to a deep sleep and when his or her consciousness resumes, he or she might have trouble remembering the seizure or doing other things such as writing.
Here is a summarized list of some of the symptoms of seizures for each stage. During early stage, the patient may experience blurring of vision, racing thoughts, stomach feeling, dizziness, headache, nausea, numbness, tingling sensations and the seeing a bright light. A seizure may also begin without any symptom of its beginning or warning. During the middle stage the patient may experience blackout, confusion, out of body experience, convulsion, difficulty breathing, chewing movements, eye rolling, inability to move, incontinence, shaking, teeth clenching, tongue biting, twitching and jerking movements and heart racing. Then in the last stage, the patient may have some physical injuries like bruises, wounds or cut tongue. The patient may also fall into a deep sleep, feel greatly exhausted, headache, nausea, shame, embarrassment, thirst weakness and many others.
