Can seizures be caused by environmental factors?

Can seizures be caused by environmental factors?

These types of epilepsies are the result of changes in many genes. These genes can also be affected by environmental factors. When this happens, there is a higher chance of epilepsy in other family members, but no clear pattern of inheritance.

Can the cause of a seizure be identified?

Medical history or MRI will identify a cause (such as trauma, stroke or meningitis) in about half of the people who have focal seizures. Developmental scars — ones that occur as part of fetal and early growth of the brain — are common causes of focal seizures in children.

Can climate change cause seizures?

The researchers found that people were most likely to experience a seizure during times of high relative air humidity and low atmospheric pressure—conditions that can cause wind, rain, thunderstorms, and even tornadoes. Finally, the researchers found that low air temperatures did not have an effect on seizure risk.

What can trigger a seizure?

Abnormal electrical activity in the brain triggers seizure activity. A person may have a seizure disorder (epilepsy) and require medications. Other factors such as hypoglycemia (low blood sugar), which is a diabetic reaction, may cause seizures. Meningitis or a head injury may also cause a seizure.

Can sounds trigger seizures?

Similar to the flashing lights, music and loud noises can cause a person to have a seizure. This type of trigger is very difficult to research and understand. The short definition is that the sound causes over stimulation to the nerves in the brain.

What are the signs of epilepsy?

Though seizures are the main symptom of all types of epilepsy, the full scope of epilepsy symptoms and signs varies. Common symptoms include muscle jerking and contractions, brief loss of consciousness or awareness, weakness, anxiety, and staring.

What are the causes of epilepsy?

Some of the main causes of epilepsy include: Low oxygen during birth. Head injuries that occur during birth or from accidents during youth or adulthood. Brain tumors. Genetic conditions that result in brain injury, such as tuberous sclerosis. Infections such as meningitis or encephalitis.
