What happens in the brain epilepsy?
In epilepsy the brain’s electrical rhythms have a tendency to become imbalanced, resulting in recurrent seizures. In patients with seizures, the normal electrical pattern is disrupted by sudden and synchronized bursts of electrical energy that may briefly affect their consciousness, movements or sensations.

What causes brain epilepsy?
Abnormalities in the brain, including brain tumors or vascular malformations such as arteriovenous malformations (AVMs) and cavernous malformations, can cause epilepsy. Stroke is a leading cause of epilepsy in adults older than age 35.
How serious is a brain seizure?
Generally speaking, a generalized tonic-clonic seizure lasting 5 minutes or longer is a medical emergency. If seizures can’t be stopped or repeated seizures occur one right after another, permanent injury or death can occur.
What epilepsy means?
Epilepsy, which is sometimes called a seizure disorder, is a disorder of the brain. A person is diagnosed with epilepsy when they have had two or more seizures. A seizure is a short change in normal brain activity. Seizures are the main sign of epilepsy.
What happens if EEG is abnormal?
Abnormal results on an EEG test may be due to: Abnormal bleeding (hemorrhage) An abnormal structure in the brain (such as a brain tumor) Tissue death due to a blockage in blood flow (cerebral infarction)
Is epilepsy a mental illness?
Epilepsy is not a mental illness. In fact, the vast majority of people living with epilepsy have no cognitive or psychological problem. For the most part, psychological issues in epilepsy are limited to people with severe and uncontrolled epilepsy.

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.
Will an EEG show past seizures?
The likelihood of recording a seizure during a routine EEG is small. The EEG generally records brain waves between seizures, called interictal brain waves. These waves may or may not show evidence of seizure activity.
What are 10 conditions diagnosed with an EEG?

Can seizures cause brain damage?
To summarize, prolonged seizures can result in brain damage, while recurring seizures can also have adverse effects on brain functioning. In turn, traumatic brain injuries can also lead to various types of seizures, which may cause further damage.
What happens right before a seizure?
Seizure warning signs before the first ‘full-blown’ seizures
These warning signs may include feeling “funny” or dizzy, or having jerking and twitching for several years. Other signs include fainting, headaches, vomiting, losing sensation in a certain parts of the body, daydreaming, and blackouts.
