seizures involve brief and sudden lapses of consciousness. Patient may seem disconnected
from the surrounding people and not respond to them. Patient may also stare
blankly into space, follow by is a quick return to normal level of alertness. These
types of seizures typically last only a few seconds, and the patient may not even
remember having one (Lava, 2017). This type of seizures usually does not lead
to physical injuries.

seizures are most commonly observed in children and often have a genetic predisposition.

In general, seizures are caused by abnormal electrical impulses originating
from neurons in the brain. Normal functions of the brain will send electrical
and chemical signals via connecting synapses. In individuals who experience seizures,
however, the brain’s usual electrical activity is altered. In an event of an
absence seizure, these electrical signals are constant repeating themselves
over 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 have
altered levels of the chemical messengers that help neurotransmitters (Mayo
Clinic, 2017).

seizures are classified into two categories: typical and atypical. Typical
absence seizures begin abruptly, last 10 to 30 seconds, and resolve themselves
without complications. Generally speaking, typical absence seizures have no observable
cause. During the seizure, patient may fumble their hands, flutter their
eyelids, smack their lips, or make chewing motions. When the seizure passes,
the patient resumes activity as if nothing had occurred, with no memory of the
event and no lingering effects. Atypical seizures are similar to typical
seizures; however, they tend to begin slower, last longer (up to a few
minutes), and can cause the patient to slump (of posture) or fall down. The
patient may also feel confused for a short period of time after regaining
consciousness. While the cause of atypical seizures is still unknown, they are
sometimes traced to abnormalities in the brain that were congenital, caused by
trauma, or from health complications such as liver or kidney disease. This type
of seizures may continue into adulthood (Lava, 2017).

seizure is considered an idiopathic disorder in early childhood and is rare
after age 20.  Some patients must take
anti-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 have
any related disorders with side effects for dental treatment. However, it can
increase the risks of dental caries, oral trauma, ulcerations, lacerations such
as bite injuries to the tongue, and glossitis as a result of medication-induced
B12 deficiency. Also, anticonvulsant medications might induce gingival
hyperplasia, bleeding gums, and delayed healing (Fitzpatrick, J.J., McArdle,
N.S., Wilson, M.H., Stassen, L.F., 2008).
