Seizures are characterized by the uncontrollable bodily movements that are instigated by erratic electrical activity inside the brain. The indications of a seizure tend to vary based on the region of the brain that is affected. Tonic or grand mal seizures are characterized by the classic sense of convulsions along with muscle jerking and loss of consciousness.
An individual suffering from a partial seizure can appear to be in a daze. There is rapid eye blinking and an absent look on the face. Remember that a seizure of any type can last for a few seconds up to a few minutes. The medications that are given to prevent and manage seizures are called as anticonvulsants.
The seizures are more likely to occur among individuals who have epilepsy. Seizures typically manifest with this condition and a minimum of 2 seizures unexplained by other means are required for a diagnosis of the condition.
The electrical impulse signals in the brain of an epileptic are in disarray which results to seizures. Always bear in mind that epilepsy requires continuous assessment and treatment. Certain activities such as driving and swimming are dangerous due to the unpredictable seizure activity that can occur at any time. Some of the possible causes of epilepsy include head trauma, hereditary factors, prenatal injury, developmental disorders as well as dementia, diseases that affect the brain such as meningitis, viral encephalitis, AIDS and other medical conditions.
There are certain diseases that can also cause seizure activity in the brain. These diseases disrupt with the electrical impulses inside the brain. Some of the diseases that are known to trigger seizure activity include Alzheimer’s disease, brain abscesses, advanced liver disease, diseases of the nervous system and brain infections.
The other conditions that have the capacity of prompting seizures include anomalous structure of blood vessels inside the brain, congenital diseases, brain tumors, high blood pressure, transient ischemic attack as well as problems linked with pregnancy.
There are various injuries especially to the head that can cause seizures. Take note that these injuries disrupt the electrical impulses in the brain that can lead to seizures. Even though having a seizure of any form is an issue for concern, a single seizure does not indicate that the individual is epileptic.
Some of the recognized events that might cause seizures include a head injury such as those that occur while playing sports or in vehicular accidents, electrical injuries, choking, poisonous insect stings or bites as well as injuries during pregnancy or child birth.
Other possible causes
There are also other circumstances that can disrupt the normal electrical activity in the brain. An individual who is alcoholic can experience seizures if he/she stops drinking during the withdrawal. In some cases, a craniotomy which is a surgical procedure that involves opening the skull can also cause an episode. Even drug addicts who stop using illicit drugs can also end up with seizures. Prescription drugs can also cause seizures either as side effects or after cessation of use. In addition, high fever especially in children can also induce seizures.
