Causes of Epilepsy

Epilepsy, seizures or fits occur due to a disturbed brain function. This arises due to different causes which varies from person to person.

We now know that epilepsy is due to disturbed brain function. But what brings about these changes?

There are different causes for seizures or fits. These vary from person to person.

In several cases, no trigger is detected. Some seizures are idiopathic, in other words the cause of the seizure can not be identified. Such seizures are more common among the young, aged between 5 - 20 years. These individuals have no other neurological complaints, but often have a family history.

Sometimes seizures are related to a temporary condition, often arising as result of exposure to or withdrawal from drugs or alcohol, or as a result of abnormal levels of lood sodium or glucose. In these cases the seizures subside once the underlying problem is addressed.

Some of the important causes of epilepsy are listed below-

  • Developmental problems or congenital problems are known to cause epilepsy.
  • Prenatal or neonatal injuries may also be the causative factors.
  • Injury to the brain, such as a head injury, excites the brain tissue abnormally . Seizures commence within 2 years of the injury; this is commonly observed in young adults.
  • Disorders, such as stroke or TLA, that affects the blood vessels, are the most common reasons for seizures in the elderly.
  • Degenerative disorders such as Alzheimer’s disease may also bring about seizures.
  • Hormonal changes during menstruation or pregnancy can also induce an epileptic attack.
  • Complications related to HIV infection or other immune disorders may cause epilepsy.
  • Tumors and brain lesions give rise to partial or focal seizures that may evolve to more serious types.More common after 30 years.
  • Infections such as meningitis, encephalitis, neurosyphylis, or brain abscess may cause seizures.This may be reversed once the infection is cured.
  • Infection with tapeworm – sometimes the egg of the pork tapeworm can get lodged in a portion of the brain and can be the cause of epileptic fits.
  • Metabolic abnormalities may cause epilepsy in people of any age. Some of these illnesses are listed below-
    • Diabetes
    • Kidney failure
    • Electrolyte imbalance
    • Phenylketoneuria
    • Nutritional deficiency
    • Sensory stimuli such as Lights, sounds and touch are also capable of triggering convulsions. The ‘seizure threshold’ or the amount of stimulation that can trigger a seizure is low in several people who are epileptic.
    • Lack of sleep, taking or skipping certain doses of medicines can also start the seizures in an individual whose seizures are under control.

My son Michael Mirai was born with a rare type of epilepsy called Dravet syndrome, also known as Severe Myoclonic Epilepsy of Infancy [SMEI]. This is a rare and catastrophic form of intractable epilepsy that begins in infancy. Individuals with SMEI suffer from intellectual disabilities as well as severe behavioral and development delays. All effort made to be sure he did not live his life miserably with deadly disease proof abortive. I have carried him to different Doctors, use different prescription drug all to no avail.
Dr. Lawson!!! (with tears of joy) I will forever be indebted to you. Your medicine worked perfectly well and now my son is cured of Epilepsy completely. Continue your good job......

My daughter aged 13 years just suffered from fits for the first time. She attained age and the illness occurred on the 7th day morning of her second month's menstruation. She was partially unconscious for about 20 minutes followed with heavy vomiting several times. Doctor advised for several tests including ct scan. is it occurred due to some hormone changes in body, loss of blood ect? is it curable?
