Seizure

If you or a loved one has ever had a seizure, you know how intense, frightening, and perplexing the experience can be. It is, however, not as dangerous as you might think. In fact, seizures are so common that up to 10% of people worldwide will experience at least one seizure at some point in their lifetime. Yet, having one seizure does not indicate that you have epilepsy, even if they are closely related.
A seizure is a temporary disturbance in the brain’s electric activity that causes dramatic or no symptoms. It’s a complex neurological event with various possible causes. There are nearly 29 different types of seizures, which are often difficult to distinguish due to the time span for which they occur. But, understanding everything about seizures is essential for improving your overall health and wellness.

Symptoms of Seizure

Symptoms of seizures usually vary depending on the type. Some general warning signs and symptoms of an episode include:

Abnormal jerky movements of arms and legs

Loss of consciousness

Frothing or drooling from the mouth

Urinary incontinence

Stiffening of body

Loss of balance

Blank starring

Psychic symptoms (such as fear, anxiety, or a feeling of déjà vu)

Weird feeling in the stomach

Repetitive, uncontrolled movements such as lip-smacking, chewing motion, and rubbing hands

Confusion and extreme tiredness after a seizure

In most cases, symptoms appear quickly and vanish in a few seconds. In others, they stay for several minutes. However, if the symptoms last for more than 5 minutes, consider it a medical emergency and call an ambulance right away.

Triggers of Seizure

Seizures are unpredictable and can affect anyone with no indication of their cause. Although each person has their own set of triggers, some things or situations that affect the brain to bring on a convulsive event include:

  • Head injuries
  • Genetic disorder
  • Improper sleep schedule
  • Extreme stress
  • Use of recreational drugs like cocaine and heroin
  • Alcohol abuse or withdrawal
  • Epilepsy
  • Birth defects
  • Brain injury during birth
  • Brain cancer
  • Brain infections like meningitis
  • Stroke
  • Uncontrolled fever
  • Hormonal changes during monthly periods
  • Some prescription medications (anti-depressants, benzodiazepine, anti-histamine, etc.)
  • Abnormal blood glucose and electrolyte levels

Diagnosis and Treatment

Identifying the type of seizure a person has can be tricky. So before making a diagnosis, your doctor may take a complete medical history and the episode you experienced to determine the pattern of occurrence. Your doctor may also perform a neurological exam and order EEG, PET, MRI scan, and other blood tests as part of your complete evaluation. 

Usually, a random seizure doesn’t require treatment unless it has occurred more than 2 to 3 times. Your doctor will be then likely to prescribe specific treatments based on your medical evaluation, which include:

  • Anti-convulsant medications
  • Surgery
  • Vagal nerve stimulation
  • Deep brain stimulation (Lobectomy)
  • Dietary therapy (mostly recommended for children)

Keep in mind that seizures are manageable—if you know what causes them. You may want to work with your doctor to prevent the occurrence and improve your quality of life.

FAQ's :

Can you inherit seizures from your parents?
While uncommon, it is still possible if one of your parents has a genetic condition that causes seizures, like genetic epilepsy. In such a scenario, you’re two to four times at greater risk of having the condition.
What genes are responsible for seizures?
In the absence of other precipitating factors such as high fever, head trauma, or brain infection, epilepsy seems to be one of the significant causes of seizures. In fact, many forms of epilepsy have a strong genetic basis with mutations in over 500 specific genes such as SCN1A, SCN9A, GABRD, KCNQ2, and CACNB4 linked to several systemic abnormalities and epilepsy or seizures.
Is there a genetic test available for epilepsy?
Several genetic tests are available to help identify your genetic predisposition to epilepsy. Some tests look for specific genes or groups of genes, whereas others target chromosomes. The results of biomarker testing may vary depending on the laboratory. The most common tests are:
•   Whole exome sequencing
•   Targeted sequencing
•   Chromosomal microarray analysis
•   Epilepsy specific panel testing
What result can I expect from genetic testing?
A genetic test can have significant implications regarding treatment and reproductive options. If you are epileptic, a genetic test can determine whether you are resistant to anti-epileptic drugs. It may also provide valuable information about how epileptic genes are passed down through your family members so that you can make informed decisions about the preventive steps.
How do I know if I need genetic testing?
Genetic testing isn’t usually recommended for everyone. Still, it can be pretty helpful for those who have a family history of epilepsy or any neurological defects.
