Causes Of Epilepsy

Epilepsy is a general term for the tendency to have seizures. Epilepsy is usually diagnosed only after a person has had more than one seizure.

Epilepsy is usually caused by brain injury. The causes of epilepsy are not known by most people.

What Are Seizures?

Seizures are caused by an excessive amount of electrical impulses reaching the brain that exceeds their normal levels. The electrical impulses can spread to other areas creating an uncontrolled flood of activity. These electrical impulses can cause convulsions or twitches by transmitting them to muscles.

Which Seizures Are There?

There are two kinds of seizures.

Focal seizures.

Seizures can cause abnormal brain activity in one area of the brain. They can lead to loss of consciousness. Or, you might remain alert.

Without losing consciousness. You may experience changes in your mood, your perception of smell and taste, as well as altered hearing, sight, touch, or senses. It is possible to jerk your arm or leg unintentionally, feel dizziness or tingling sensations, and even see flashing lights. Loss of consciousness. These seizures may cause your sense of awareness to be reduced or lost. Sometimes you may look into the distance, chew, rub your hands or walk in circles.

Generalized seizures.

Generalized seizures can affect all parts of the brain. Six kinds of generalized seizures are available:

Absence seizures are most common in children. They involve tiny movements like eye blinking and lip smacking.

Tonic seizures cause stiffening of the muscles and back in your arms, legs, and can sometimes lead to falling down.

Atonic seizures take away your muscle control. Drop seizures are also known as these because you can fall to the ground.

Many times, clonic seizures can cause repetitive, jerking movements to your neck, face, arms, and head.

Myoclonic seizures can be described as short, quick and often jerking movements of your arms or legs.

Grand-mal seizures were once known as tonic-clonic seizures. They can lead you to become unconscious, lose control of your body and even shake. Your bladder may become obstructed or you might bite your lips.

How can Epilepsy be caused?

Each year, there are approximately 180,000 cases of epilepsy. Children account for 30%. Most of the victims are elderly people and children.

Only a small percentage of epilepsy cases have a known cause. The most common cause of seizures is brain injury. Epilepsy can be caused by:

The family history. The role of genes is important. Epilepsy can affect up to 40% of cases. This is because epilepsy patients have a higher likelihood of getting it. Epilepsy is not caused by one gene. Experts believe there could be up to 500 genes.

You have a greater chance of developing epilepsy if you are related to someone with it, such as a parent who has epilepsy or an older sibling. Although doctors aren't certain how the condition is passed on, they believe it could be due to a genetic mutation in brain nerve cells. You can also have the mutation without ever developing epilepsy.

Experts believe that the problem may lie in a combination of genes and a medical condition.

Birth injury before, during or shortly after birth. The possibility of epilepsy increases if the brain develops in the wrong way in the womb. There are many causes that brain damage may occur in babies while they're still developing.

This can lead to epilepsy if there is a problem during pregnancy or if the baby has brain defects.

Head or brain trauma. Either can trigger seizures. Sometimes, they disappear. If they stop, it's not an indication that you have epilepsy. If they do not stop, it is a sign you may have post-traumatic epilepsy (or PTE). You can get epilepsy even during pregnancy. It is possible to develop epilepsy long after you have suffered a brain injury. Sometimes, it can take years.

Conditions of the brain. Epilepsy is most common in those over 35 who have suffered brain damage after a stroke, or brain surgery. The following brain conditions can cause epilepsy:

Infectious diseases. Epilepsy can also be caused by infections, particularly if the infection infects your brain. These are some of the common reasons for epilepsy:

Developmental disorders. This could result from the way the brain developed during pregnancy. Some conditions increase your chances of developing epilepsy.

The genetic condition neurofibromatosis is a disorder that results in non-cancerous growth of tumors on nerve covers. There is no known cause for epilepsy in as high as 70% of the cases.

What are the causes of seizures?

Although epilepsy is not usually caused by a specific cause, there are certain factors that can trigger seizures. These triggers are easy to avoid and can make it easier for you to live with epilepsy.

About 1 in 2 epileptic women experience seizures during menstrual cycles. It is possible to help your epilepsy by changing or adding drugs prior to menstrual periods.
