What is Epilepsy?


Epileptic seizure (or seizure) is a clinical condition that occurs when the normal activity of the brain is disrupted as a result of temporary abnormal electrical activity in nerve cells. Epilepsy, also known as "Sara Disease" among the people, manifests itself with epileptic seizures. Epilepsy is a chronic disease. It develops in people who have brain damage during or after birth for any reason. 

It is a disease seen in 1% of the population in the world and in our country, and about 70% of these patients can be treated with epilepsy drugs called antiepileptic.

More than 30 percent of all epileptic patients continue to have seizures despite taking appropriate medications (anticonvulsants) for epileptic seizures, a condition called refractory epilepsy. Several treatment options are available for patients in this condition.

Types of Epilepsy

Doctors have described more than 30 different types of seizures, ranging from very brief shifts of attention to prolonged seizures. The frequency of seizures is also variable, with some patients having less than one seizure per year, while others may experience multiple seizures per day. Seizures are generally divided into two main groups (partial or generalized seizures) depending on the area of abnormal electrical activity in the brain. 

Partial Seizures: Partial seizures begin and affect only one part of the brain. Also known as 'focal', these seizures can be seen in the following ways.

Secondary Generalized: seizure that begins as a partial seizure and spreads to the rest of the brain, becoming a generalized seizure.

Complex: The person experiences changes in consciousness and loss of consciousness, which causes confusion. The person may experience a dreamlike state or exhibit strange and repetitive behaviors such as emotional outbursts or blinks and tics. 

Generalized Seizures: Generalized seizures occur as a result of abnormal activity in both halves of the brain simultaneously. 

Absence Seizures: Associated with a shift of consciousness in which the person seems to be immersed in the void. This condition usually begins in childhood and is confused with attention deficit. 

Simple seizures: Despite seizure activity, the person is conscious and remains aware of those around them. An abnormal twitching, lethargy, sweating, drowsiness, nausea, disturbances of perception and memory, and a feeling of 'deja vu' may occur.

Treatment Options for Drug-Resistant Epilepsy 

Epilepsy Surgery

It is the surgical intervention of areas in the brain that cause epileptic seizures and do not perform their normal functions.

Invasive Vagus Nerve Stimulation (iVNS)

With a surgical intervention, a battery is placed under the chest and an electrode wire is placed on the vagus nerve in the neck. With the help of the electrode, the vagus nerve next to the carotid artery is stimulated at regular intervals.

Antiepileptic Drugs

They are designed to correct the chemical imbalance in brain cells that causes seizures. These drugs work in different ways, although some are not yet fully understood.


Transcutaneous Vagus Nerve Stimulation (tVNS)

It is a treatment option that stimulates the vagus nerve with the help of an electrode attached to the ear and stimulates the centers in the brain.
