I Have Seizures

Causes of Epilepsy

Epilepsy is a general term for the tendency to accept seizures. Epilepsy is normally diagnosed only afterwards a person has had more one seizure.

When identifiable, the causes of epilepsy usually involve some course of injury to the brain. For most people, though, epilepsy's causes aren't known.

What Are Seizures?

A seizure occurs when a burst of electrical impulses in the brain escape their normal limits. They spread to neighboring areas and create an uncontrolled storm of electrical activity. The electric impulses tin can be transmitted to the muscles, causing twitches or convulsions.

What Are the Types of Seizures?

At that place are 2 types of seizures:

Focal seizures. These seizures involve abnormal activity in just one part of your brain. You may lose consciousness, or you may stay warning when yous take them.

• Without loss of consciousness. These seizures may just change your emotions, or alter your sense of sight, smell, gustatory modality, or sound. You might likewise jerk an arm or a leg without pregnant to, or feel tingling, dizziness, or see flashing lights.
• With loss of consciousness. During these seizures, you lot aren't quite aware of your environs as usual. You lot may stare into space, or motility repetitively by chewing, rubbing your hands, or walking in circles.

Generalized seizures. This type of seizure tends to involve all the parts of your brain. There are six kinds of generalized seizures:

• Absence seizures happen mostly in children and involve small movements such every bit lip smacking or eye blinking.
• Tonic seizures make y'all stiffen the muscles in your arms, legs, back and sometimes fall downwardly as a upshot.
• Atonic seizures take away your muscle control. They're besides chosen drop seizures, considering they can make you collapse onto the flooring.
• Clonic seizures often make you repeat jerking movements in your neck, face, and arms.
• Myoclonic seizures involve short, twitching and jerking motions in your arms and legs.
• Tonic-clonic seizures, which used to be chosen grand-mal seizures, tin make you lose consciousness, stiffen your whole torso, and milk shake. Yous may likewise bite your tongue or lose control of your float.

What Are the Causes of Epilepsy?

At that place are around 180,000 new cases of epilepsy each year. Almost 30% occur in children. Children and elderly adults are the ones most often affected.

There is a clear cause for epilepsy in only a minority of the cases. Typically, the known causes of seizure involve some injury to the brain. Some of the main causes of epilepsy include:

Family history. Genes play a big part. As many as forty% of all epilepsy cases happen because the person with it has a genetic makeup that makes them more than probable to get it. There isn't just one gene behind epilepsy. In fact, some experts remember there may exist as many as 500.

If yous take a parent or a sibling with epilepsy, yous have a higher take a chance of getting it than someone who doesn't. Doctors aren't sure how it'due south passed downwards, just they think it may have something to do with a cistron mutation that affects nervus cells in the brain. Information technology'southward also possible to accept this mutation and never get epilepsy.

Experts think the combination of genetics and something else, like a medical condition, may be to blame.

Injury before, during, or soon after birth. Any issues with encephalon development in the womb or in early infancy heighten the chance of epilepsy. Brain damage can happen to babies in the womb for many reasons, including:

• An infection in the female parent
• Poor nutrition
• Besides little oxygen

If there are problems during birth, or if a baby is built-in with brain defects, this can also bring on epilepsy.

Head or brain trauma. Either tin can trigger seizures. Sometimes they get abroad. If they practice, you don't take epilepsy. However, if they go along, that's a sign that you have post-traumatic epilepsy, or PTE. It can also happen during birth. Yous may not get epilepsy until long after your encephalon injury -- sometimes years later.

Brain conditions. Most cases of epilepsy in people older than 35 happen considering of encephalon impairment from a stroke or even after brain surgery. Other encephalon problems that can trigger epilepsy include:

• Tumor
• Blood vessel problems, like the hardening of your encephalon's arteries
• Stroke
• Alzheimer'south illness
• Tuberous sclerosis, a genetic condition that tin cause growths in the brain.

Infectious diseases. Conditions caused by a viral or bacterial infection can crusade epilepsy, too, especially if they infect your brain. Some common culprits are:

• AIDS
• Viral encephalitis
• Meningitis

Developmental disorders. It could exist caused by how the encephalon itself developed in the womb. Certain disorders raise your take chances of epilepsy, including:

• Down's syndrome
• Autism
• Neurofibromatosis, a genetic condition that causes noncancerous tumors to grow on nervus coverings.

In up to 70% of all cases of epilepsy in adults and children, no cause tin be discovered.

What Are the Causes of Seizures

Although the underlying causes of epilepsy are usually non known, certain factors are known to provoke seizures in people with epilepsy. Avoiding these triggers tin help yous avoid seizures and live better with epilepsy:

• Missing medication doses
• Heavy alcohol use
• Cocaine, ecstasy, or other illegal drugs
• Lack of sleep
• Other medicines that interfere with seizure medications

• Flashing lights, images, and repetitive patterns may cause seizures in persons with photosensitive seizure disorder.

For near 1 in 2 women with epilepsy, seizures tend to occur more around the time of menstrual periods. Irresolute or adding certain drugs earlier menstrual periods tin help.
