Types of Epilepsy

No More Shadows

Often people are only informed about -Epilepsy- but this case goes much deeper. There is not just one form of Epilepsy; There are many that are known at this moment. They are often notified as the epilepsies. Each type of epilepsy also has differences in the types of seizures an individual encounters.

Some of these include:
Febrile Epilepsy      Benign Rolandic Epilepsy      Reflex Epilepsy  Temporal Lobe Epilepsy       Frontal Lobe Epilespy

Febrile Epilepsy
 Febrile Epilepsy occurs in children ages 3 months to 5 years. This results in Febrile seizures, which are tonic-clonic seizures with a high fever, and often occur in 2% - 5% of most children. If Epilepsy runs in the family, such as mothers, fathers, siblings, and other relatives, especially Febril Epilepsy, there is a slight chance that the child is likely to have them as well.
In a sense, you might think that because fevers occur with this type of Epilepsy, cooling a child's body or head may preventy these siezures. Studies have shown that cooling the temperature of a child's body does not prove to be effective. Giving a child medications for fevers or giving them baths, does not prevent these types of seizures. They will only make the fevers the child has feel better. 
 If there is abnormal development before the febrile seizure, complex febrile seizures (lasting longer than 15 minutes or more than one in 24 hours,) or a parent or brother that has no fever with seizures, 2.5% these children is more likely to develop other epilepsies later in life.
          Outlook: Half of the children with Febrile Epilepsy that have their first seizure before their first birthday will have atleast one more. A fourth of those older than 1 when they have their first febrile seizure will experience more. Most children with Febrile Epilepsy do not have these seizures without fevers after the age of five.
     
 
Benign Rolandic Epilepsy
This type of Epilepsy is named after the rolandic area of the brain. The rolandic area in the brain is the part of the brain that controls the movement in the affected areas of the face. It is also known as the Benign Childhood Epilepsy with centrotemporal spikes. This refers to the type of spikes seen on the child's EEG, a test that helps define the type of syndrome the child has.
Benign Rolandic Epilepsy occurs with partial seizures. This may include any or all of the effects of this type of seizure: twitching, numbness, tingling of the face or tongue, which may cause speech interferences and drooling. These seizures only last about 2 minutes while the child will remain fully conscious.
Benign Rolandic Epilepsy often is about 15% of  the types of Epilepsies in children. It is often that it begins in the age of 6 to 8 years old, but the starting range may also range from 3 to 13 years old. This syndrome is more likely to affect boys, but can affect either gender.
              Outlook: It is very rare, but completely possible for the seizures the individual encounters from Benign Rolandic Epilepsy to stop by age 15.
 
 
Reflex Epilepsy
Reflex Epilepsy is a syndrome where a certain stimulus brings on the seizures a child has. The stimulus that triggers these seizures can be anything in the enviorment, or something as simple as writing or reading, sometimes even talking about a certain subject. It has also been noted that certian patterns such as the brushing of the teeth, moving excalator steps, back rubbing, etc etc, can cause seizures as well.Certain video games and the switching of the different patterns in the game, tv shows, or not limiting time with these activities can also cause seizures. Sleep deprivation or stress from video games has also been proven to trigger a seizure in an individual. However, it is wise to know that seizures that occur after the game is stopped from play is not caused by the game. The cause of the seizure is elsewhere.  The types of seizures that occur in Relflex Epilepsy are usually varied, but mostly include mono-clonic seizures, absence seizures, or myoclonic seizures.
The most common type of Reflex Epilepsy is the photosensitive epilepsy, in which the seizures are triggered by flashing lights or loud sounds. Other times, certain colors may trigger seizures. This may make it extremely hard to drive because of the sun flasing through the trees, this can produce the same effect as a strobe-light would.  These triggers usually trigger primary generalized seizures and occasionaly partial siezures.Reflex Epilepsy often occurs in childhood and is mostly outgrown before the individual hits hood. If a person does not stop having seizure caused by photosenstivity by the age of 25, it is likely that the individual will never stop having these seizures. However, this is not always the case. It is completely possible that an individual may outgrow seizures. Other types of Reflex Epilepsies can occur at any age, but only affect a small percentage of people with Epilepsy.
           Outlook: Most seizures caused by Reflex Epilepsies can be controlled with low doseages of medication. Some people outgrow their seizures, but the decrease of susceptibility may not happen for many years. 75% of the people with Reflex Epilepsy will continue to have seizures caused by Reflex Epilepsy if they are not treated before the age of 25. Stopping treatment will also cause the seizures to reappear.
 
 
Temporal Lobe Epilepsy
Temporal Lobe Epilepsy often occurs with Complex-partial and Simple-partial seizures. They begin in the temporal lobe of the brain and occur with a mixture of feelings, emotions, thoughts, and experiences. Some of these may be familure, others completely foreign to the individual. In some cases old memories from the individual's childhood or memories that were repressed. If the seizures have occured for more that 5 years, the individual may have memory problems occuring. Most often, these problems aren't severe. Other things that may occur are hallucinations of voices, figures, music, smells, and tastes. These are called "auras" (ore-uh-z) or "warnings" that will last anywhere from a few seconds to a minute or two. These are called warnings because it is often a sign that a bigger seizure is about to happen. Some of these seizures may not even be felt at all, at other times the individual may be consumed with fear during the seizure. They are almost impossible to describe, especially when it is a child in whom the seizures are occuring in.
Temporal Lobe Epilepsy occurs in the two temporal lobes of the brain (one on each side). These lobes are the most common area for the partial seizures to start because they start in one localized area most of the time. This type of Epilepsy can occur at any age and can often be a result of a head injury or infection that affects the brain. Other causes are unknown. Most children who have TLE usually pause what they are doing and do not respond to any action or voice when spoken to. 40%-80% of the individuals with TLE often engage in repetitive acts called automatisms. This may include smacking of the lips or rubbing the hands together, etc. etc.
In 60% of the individuals with Temporal Lobe Epilepsy, the seizures spread from the temporal lobes to a larger part of the brain where convulsive (grand-mal) seizures are the result. The process of the seizures spreading to a larger part of the brain is called secondary generalization.  
                   Outlook: The outlook greatly varies on the type of seizures a person has from Temporal Lobe Epilepsy. Half of the children with TLE may outgrow it before too long. If the various medications or other treatments are unsuccessful any individual may be evaluated for surgery which can result in fairly good or complete control in their seizures.
 
 
Frontal Lobe Epilepsy
The frontal lobes of the brain are fairly large and include many of the areads that do not have a precisly known function. When seizures begin with this type of Epilepsy, there may be know symptoms until it spreads to other parts of the brain causing tonic-clonic seizures. When the areas of the brain that control the movement is affected, many abnormal movements often occur on the opposite side of the body. This may cause weakness or even inability to move or use certain muscles, such as in the arms, legs, or even muscles that allow someone to speak.
Alot of times frontal lobe seizures are common with complex partial seizures, which tend to be shorter in Frontal Lobe Epilepsy than the ones that start in teh Temporal Lobe. These seizures are less likely to be followed by confusion or tiredness, and they more often occur in clusters. Laughing and very rarely crying may occur in frontal lobe seizures. Also, smirking, giggling, or full laughter may occur.
            Outlook: Frontal Lobe Epilepsy also varies depending on the causes of the seizures. People that have a brain malformation or acquire lesions such as scar tissue caused by injury are less likely to require life-long treatments for seizures by medication. If genetic reasons are the cause of the Epilepsy, the seizures may stop eventually.
