Absenceseizures involve brief and sudden lapses of consciousness.
Patient may seem disconnectedfrom the surrounding people and not respond to them. Patient may also stareblankly into space, follow by is a quick return to normal level of alertness. Thesetypes of seizures typically last only a few seconds, and the patient may not evenremember having one (Lava, 2017). This type of seizures usually does not leadto physical injuries. Absenceseizures are most commonly observed in children and often have a genetic predisposition.In general, seizures are caused by abnormal electrical impulses originatingfrom neurons in the brain. Normal functions of the brain will send electricaland chemical signals via connecting synapses.
In individuals who experience seizures,however, the brain’s usual electrical activity is altered. In an event of anabsence seizure, these electrical signals are constant repeating themselvesover and over in a three-second pattern, this could be compared to an altered”loop” in the individual’s conscience. People who have seizures may also havealtered levels of the chemical messengers that help neurotransmitters (MayoClinic, 2017). Absenceseizures are classified into two categories: typical and atypical. Typicalabsence seizures begin abruptly, last 10 to 30 seconds, and resolve themselveswithout complications. Generally speaking, typical absence seizures have no observablecause.
During the seizure, patient may fumble their hands, flutter theireyelids, smack their lips, or make chewing motions. When the seizure passes,the patient resumes activity as if nothing had occurred, with no memory of theevent and no lingering effects. Atypical seizures are similar to typicalseizures; however, they tend to begin slower, last longer (up to a fewminutes), and can cause the patient to slump (of posture) or fall down. Thepatient may also feel confused for a short period of time after regainingconsciousness. While the cause of atypical seizures is still unknown, they aresometimes traced to abnormalities in the brain that were congenital, caused bytrauma, or from health complications such as liver or kidney disease.
This typeof seizures may continue into adulthood (Lava, 2017).Absenceseizure is considered an idiopathic disorder in early childhood and is rareafter age 20. Some patients must takeanti-seizure (anticonvulsant) medications throughout life to prevent seizures.Some might have full convulsions, such as generalized tonic-clonic seizures,eventually, which will cause several general health concerns such as ADHD,learning disabilities, anxiety, and depression. Absence seizure does not haveany related disorders with side effects for dental treatment. However, it canincrease the risks of dental caries, oral trauma, ulcerations, lacerations suchas bite injuries to the tongue, and glossitis as a result of medication-inducedB12 deficiency. Also, anticonvulsant medications might induce gingivalhyperplasia, bleeding gums, and delayed healing (Fitzpatrick, J.J., McArdle,N.S., Wilson, M.H., Stassen, L.F., 2008).
