Our brain is arguably the most complex organ in our body. To date, the
depth of its function is still not well understood. Its complexity allows us to
perform all conscious actions and thoughts. Unfortunately, with the complexity
come many disorders that ail the brain.

One of the most
prevalent conditions with serious physical manifestations are seizures. There
are many causes of seizures but if the causes are unknown, you may be diagnosed
with epilepsy.
What are seizures?
The brain is a big
bundle of nerves that uses electric current to communicate. These electrical
impulses send messages to all parts of the brain as well as down the spinal
cord to communicate with the rest of the body. In some people, one or more
parts of brain may, in a sense, short circuit and cause a burst of abnormal
electrical signals. This abnormal burst interferes with normal signals and
results in a seizure.
Seizures may often
be a symptom, rather than a condition. Seizures can occur in those with
high-grade fevers, high or low blood sugar, alcohol or drug withdrawal, or as
the result of a concussion.
If the cause of
the seizure is known, and the underlying condition is resolved, it is unlikely
that a seizure would occur again. However, in some cases, the cause of the
seizures is unknown, and this may meet the classification of epilepsy.
Seizures can occur in those with high-grade fevers, high or low blood sugar, alcohol or drug withdrawal, or as the result of a concussion.
Definitions of
epilepsy may vary slightly around the world but generally epilepsy is defined
as two seizures without a known cause occurring more than 24 hours apart.
Types of seizures and
epilepsy
Many people have a general idea of what seizures look like, but seizures
can come in a variety of forms. For those with epilepsy, understanding the type
of seizures that can occur is important in order to explain to others.
Generally
speaking, there are four classifications of epilepsy: focal, generalized,
mixed, and unknown. There are also subtypes of focal and generalized, which
affect how the seizures manifest.
Focal epilepsy
Focal seizures, also known as partial seizures, occur when the abnormal
impulses are limited to a specific area within one brain hemisphere. There are
two subtypes of focal seizures: focal seizures with retained awareness and
focal seizures with loss of awareness. Focal seizures with retained awareness
were previously known as simple partial seizures. The manifestations of this
type of seizure vary in different people, but can include motor changes, such
as twitches or convulsions, sensory changes, such as a tingling sensation, as
well as autonomic changes, such as sweating and rapid heart rate.
If you meet
someone with this condition, it is likely that they can tell you the signs of
their seizures because they are aware of what is happening.
Focal seizures
with a loss of awareness, on the other hand, may be harder to describe and have
the potential to be life threatening. The manifestations of focal seizures with
loss of awareness, previously known as complex partial seizures, are similar to
those of simple partial seizures, but because the person is unaware of their
surroundings, it can result in dangerous situations, such as walking into
traffic.
If you or someone
you know has this type of epilepsy, it is important to understand its
manifestations as quickly as possible in order to better keep safe.
In Jordan, simple
partial seizures account for 14.4 percent of total epileptics and complex
partial seizures account for 32.6 percent.
Generalized epilepsy
Generalized seizures occur when the abnormality is widespread and affects
both sides of the brain. Generalized seizures have six subtypes of seizures:
absence, tonic-clonic, atonic, clonic, tonic, and myoclonic.
Tonic-clonic
seizures, also known as convulsion seizures or grand mal seizures, are the most
common and most are familiar with. In Jordan, grand mal seizures account for
22.8 percent of total epileptics and is characterized by loss of consciousness
and violent muscle spasms. Absence seizures, also known as petit mal seizures,
are more subtle in their manifestations. Most people with petit mal seizures
will seem to stare out into nothing or blank out. This type of seizure is most
common in children and usually occurs between the ages of 4 and 14.

Petit mal seizures
are not as dangerous as other types, especially long-term, but because
manifestations may be subtle, the seizures may go unnoticed. If left untreated,
it is possible to have up to 100 seizures a day and in Jordan, 7.1 percent of
those diagnosed with epilepsy have petit mal.
Myoclonic seizures
are the third most common type of generalized epilepsy (7.1 percent). This form
manifests are jerks or muscle twitches, but the person usually remains
conscious. Myoclonic seizures are not particularly dangerous, but due to the
unpredictability of it, there should still be precautions. If a person is
holding something and a jerk occurs, it is likely that whatever is being held
would be dropped.
Atonic seizures,
also known as drop attacks, results in a sudden loss of muscle strength
throughout the body. The main concern with atonic seizures is the potential
fall that may occur, which may result in injury. Tonic and clonic seizures are
similar to grand mal seizures. Tonic means prolonged muscle contractions and
clonic means rhythmic jerking.
Myths about seizures and epilepsy
There are many myths surrounding seizures that can affect an individual
living with epilepsy. The attitudes toward seizures and epileptics vary
greatly, but in Jordan there seems to be a negative social stigma surrounding
this condition.
One study found
that 38.3 percent of Jordanians believe that epileptics are less intelligent
than the average person and 9.3 percent believe that they are insane. In fact,
the intellectual capacity is the same as of any other person, but it may be
more difficult to concentrate in school due to their condition.
Similarly, 42.7
percent reported that they would not work with an epileptic and an additional
56.3 percent reported that if they were an employer, they would not hire an
epileptic.
The attitudes toward seizures and epileptics vary greatly, but in Jordan there seems to be a negative social stigma surrounding this condition.
Given the proper
treatment, most epileptics can be free of seizures entirely. There may be some
liability in certain career choices, but generally speaking, if a person is on
the proper treatment, they can be indistinguishable from the average person.
When it comes to
first aid, there are also myths, many of which can cause harm to the individual
or yourself. One of the most common is placing something, such as a towel, in
the mouth of the afflicted to prevent them from swallowing their tongue. This
myth is especially dangerous to both involved. Firstly, an individual having a
seizure cannot swallow their tongue, but the object placed in their mouth may
cause choking. Secondly, forcibly trying to insert something in the person’s
mouth while the person has a seizure may result in injury to the jaw or teeth.
Lastly, the individual having a seizure is not in control of their muscles which
relax and contract. By placing your fingers inside the person’s mouth, they
could bite your finger and not be able to release for a period of time.
Similarly, it is
also a myth that you should restrain someone who is having a seizure. This will
only bring harm to yourself or the individual. The only course of action is to
make sure the area around them is safe and remain with them until the seizure
stops. If the person is a known epileptic, it is not necessary to call 911, but
if it is the first time or the seizure lasts longer than five minutes, be sure
to call 911.
