This period can last several seconds or minutes and can be accompanied with urination or defecation. After this period there is usually some fatigue, either mild or severe depending on the duration of muscular contractions. Almost always the seizures subside within one to two minutes. Knowledge of the anatomy of the CNS along with these signs is vital in pinpointing this source area initiating the electrical imbalance. In the vast majority of cases, the cause of seizures is not known and there is no source area.
Seizures are indeed serious clinical signs.
Awareness of the environment and body is lost. This is indeed a serious aberration of normal function. The internal check points and homeostatic mechanisms are ill functioning, thus allowing these periodic surges of uncontrolled discharge to propagate through the nervous system. Rather than having a specific cause, seizures are most commonly due to a combination of factors that build up and inhibit minimal acceptable functioning. The cause of seizures can be attributed to chemical imbalances and chemical deficiencies of one kind or another.
