Can a simple test diagnose epilepsy?

Diagnosing epilepsy is not simple. Doctors gather lots of different information to assess the causes of seizures. If you have had two or more seizures that started in the brain you may be diagnosed with epilepsy. Getting a diagnosis is not always easy as there is no single test that can diagnose epilepsy.

Will an EEG show past seizures?

An EEG can usually show if you are having a seizure at the time of the test, but it can't show what happens to your brain at any other time. So even though your test results might not show any unusual activity it does not rule out having epilepsy.

Can doctors tell if you've had a seizure?

Tests for diagnosing seizures

If this is your first seizure, your doctor may want to do some scans to look at the structures in your brain. A common form of imaging is MRI. Your doctor may also want to assess how the naturally occurring activity in your brain is functioning. To do this, an EEG is performed.

What is the most accurate test to confirm a seizure?

An electroencephalogram (EEG).

The electrodes record the electrical activity of your brain, which shows up as wavy lines on an EEG recording. The EEG may reveal a pattern that tells doctors whether a seizure is likely to occur again.

What does a neurologist do for seizures?

If you have spells that may be seizures, your primary doctor probably will send you to see a neurologist, a doctor who specializes in the brain and nervous system. The neurologist will perform a complete neurological exam to find out whether an area of your brain is functioning abnormally.

Will MRI show past seizures?

People sometimes think that imaging tests such as an EEG, CT scan or an MRI will determine that they have had a seizure. However, information from tests alone can't always confirm that a seizure has occurred, or that the person has epilepsy.

Why can't epileptics donate blood?

Abstract. Throughout the world people who have epilepsy and seizures are prohibited from donating blood. These restrictions are based on the assumption that they are prone to adverse donor reactions, specifically, syncope and convulsions.

What is the root cause of epilepsy?

There are many possible causes of epilepsy, including an imbalance of nerve-signaling chemicals called neurotransmitters, tumors, strokes, and brain damage from illness or injury, or some combination of these. In the majority of cases, there may be no detectable cause for epilepsy.

Can you suddenly develop epilepsy?

Epilepsy and seizures can develop in any person at any age. Seizures and epilepsy are more common in young children and older people. About 1 in 100 people in the U.S. has had a single unprovoked seizure or has been diagnosed with epilepsy.

How do you prove you don't have epilepsy?

Your doctor may also suggest tests to detect brain abnormalities, such as: Electroencephalogram (EEG). This is the most common test used to diagnose epilepsy. In this test, electrodes are attached to your scalp with a paste-like substance or cap.

Can someone have epilepsy and not know it?

Some people with undiagnosed epilepsy may not even realize that the strange sensations or emotions they're experiencing are due to a seizure. Epileptic seizures can vary by the type of epilepsy causing them.

What is the difference between epilepsy & seizure?

A seizure is a single occurrence, whereas epilepsy is a neurological condition characterized by two or more unprovoked seizures.

What if epilepsy is left untreated?

The consequences of epilepsy can be quite severe and include shortened lifespan, excessive bodily injury, neuropsychological and psychiatric impairment, and social disability. There is evidence that seizures cause brain injury, including neuronal death and physiological dysfunction.

How many hours should a person with epilepsy sleep?

People with epilepsy should get adequate sleep - enough to feel refreshed the next day. In general, adults should try for at least 7-8 hours a night. Going to bed late (for example, 3 a.m. instead of 11 p.m.) can be compensated for by sleeping late (10 a.m. instead of 6 a.m.) and thereby avoiding sleep deprivation.

Can epilepsy go away?

The odds of becoming seizure-free are not as good for adults or for children with severe epilepsy syndromes, but it is possible that seizures may decrease or even stop over time.

What triggers epilepsy?

Missed medication, lack of sleep, stress, alcohol, and menstruation are some of the most common triggers, but there are many more. Flashing lights can cause seizures in some people, but it's much less frequent than you might imagine.

How can a neurologist tell if you had a seizure?

High-density EEG

During a high-density electroencephalogram (EEG) test, electrodes are placed on your scalp closely spaced together. Like conventional EEG , high-density EEG records brain activity. A high-density EEG test can help your doctor locate the area in your brain where seizures occur.

Can a CT scan detect a seizure?

A guideline developed by the American Academy of Neurology recommends immediate brain CT scans to screen certain emergency room patients with seizures. Evidence shows such scans can help doctors select the right treatment option.

What foods should epileptics avoid?

Stimulants such as tea, coffee, chocolate, sugar, sweets, soft drinks, excess salt, spices and animal proteins may trigger seizures by suddenly changing the body's metabolism. Some parents have reported that allergic reactions to certain foods (e.g. white flour) also seem to trigger seizures in their children.

Unusual smells, tastes, sounds, or sensations. Nausea. A Déjà vu feeling (you feel like you are experiencing something that has occurred before) Intense fear and panic.
