Focal Seizures

Focal seizures either affect a specific area of the brain or spread havoc in entirety for the brain. As mentioned, a seizure can appear unexpectedly for people; however, it is mostly evident in those who have a medical history to display signs of congenital epilepsy, strokes or are prone to frequent migraine attacks.

Types of Seizures

There are two types of seizure that occur in humans: 1) Simple; and 2) Complex focal seizures. When a focal seizure strikes, the individual may be conscious or may fall unconscious. When the person is aware of what is happening, the individual is said to be enduring a simple seizure. If these seizures continue to bother the individual, it may cause one to experience muscle spasms, numbness, nausea thereby causing vision impairment. This may also result in frequent episodes of palpitations, hallucinations and difficulty in articulating sentences. A simple partial seizure occurs predominantly in children. Simple focal seizures in children may not involve the child losing consciousness, however there are some cases where the child may fall unconscious, thus requiring treatment. Partial seizures in children in the age group of 3 to 13 are bound to disappear when the child grows and thereby falls in the age group of 14 to 16.

In a complex focal seizure the individual falls unconscious and may not remember the moment during which the seizure occurred. The individual may lose control over his body movements and chances are high that the individual may black out totally during the seizure. The time period within which the seizures take place, ranges anywhere between a couple of seconds to five minutes.

Causes of Focal Seizures

Occurrence of Seizures After a Stroke
A cerebrovascular accident, also known as CVA, is one factor that causes seizures in adults. Majority of people who have endured a stroke later develop seizures. This type of seizure and its intensity displays as to which part of the cerebral cortex has been affected. If the eye starts to twitch, there are probabilities that the frontal cortex is affected thereby causing seizures. If the hand or the leg muscles start to convulse, it has to be understood that a part that is responsible to control the leg or hand movements is affected that is causing the seizure.

Congenital Defect
Congenital epilepsy is caused when abnormal tissues in the brain pile up and is often the primary cause of seizures continuing well after the child has grown and has passed the age of 14. This type of epileptic seizure appears during childhood and refuses to cease when the child steps into adulthood.

Brain Tumor
A focal seizure in adults can also indicate the occurrence of brain tumors. It could thus be a primary symptom of brain tumor that could be originating from the brain cells and secondary that has its originate points in the brain from another part of the body that is affected.

Bacterial infections or the intake of certain long term drugs could prove to be other causative. Hope this section has answered your quandary on what causes seizures. If you have been diagnosed with seizures that re-appear in the due course of time, consulting a medical practitioner is very important. The medical practitioner will advise a conduction of the electroencephalogram (EEG) in order to understand the affected area that has an abnormal electrical activity in the brain. Blood tests coupled with EEG are the best remedies that could help the practitioner diagnose the reason and curb future events. If infection is detected to be a causative for seizure recurrence, the individual may have to continue with an antibiotic course. If brain tumor is one factor that causes seizures, it has to be surgically removed. Whatever be the cause, ample sleep, exercise routines and a good diet maintenance can contribute in controlling and curbing the occurrence of seizures.

Remember: Your health is one factor that you cannot, by no means, afford to ignore. Attend to the condition promptly and give your health the much deserved care it needs.
