Epilepsy: Detection and Treatment Methods

Epilepsy is one of the most common neurological disorders worldwide, caused by abnormal and uncontrolled electrical activity of nerve cells in the brain. These momentary changes in the brain's electrical transmission lead to epileptic seizures. Seizures can cause temporary alterations in a person's consciousness, movements, sensations, or behavior.

Experiencing a single seizure does not always mean a person has epilepsy. However, recurrent, unprovoked seizures may indicate an underlying epileptic condition. With accurate diagnosis and consistent treatment, the majority of people with epilepsy can achieve seizure control and lead active, healthy lives.

In this article, we cover what epilepsy is, its symptoms, detection and diagnostic methods, current treatment options, and when to consult a neurology specialist.

What Is Epilepsy?

Epilepsy is a chronic condition characterized by sudden and disorganized electrical discharges among groups of cells in the brain called neurons. This condition can affect only a specific region of the brain (focal) or involve the entire brain (generalized).

Epileptic seizures can manifest in various ways. While some seizures involve only a few seconds of blank staring or spacing out, others may present with full-body muscle contractions, convulsions, and loss of consciousness. The type of seizure varies depending on which area of the brain is affected.

What Are the Symptoms of Epilepsy?

Epilepsy symptoms can vary significantly from person to person and according to the type of seizure. Various signs can be observed before, during, and after a seizure.

Common symptoms associated with epilepsy include:

• Sudden detachment from surroundings and staring blankly at a single point

• Uncontrolled jerking movements and twitching in the arms and legs

• Stiffening of the entire body followed by rhythmic shaking

• Loss of consciousness or temporary confusion

• Sudden waves of fear, anxiety, or déjà vu

• Abnormal perceptions of smell, taste, or sound

• Repetitive involuntary movements such as lip-smacking, hand-rubbing, or chewing

• Fatigue, headache, and drowsiness following a seizure

Some individuals may experience a warning sensation known as an "aura" right before a seizure begins. These feelings can present as sudden dizziness, a rising discomfort in the stomach, or flashes in the visual field.

What Causes Epilepsy?

In about half of epilepsy cases, no clear underlying cause can be identified, a condition referred to as "idiopathic epilepsy." In other cases, conditions that cause brain tissue damage or electrical imbalances stand out as the primary causes.

Possible causes of epilepsy include:

• Genetic factors and family history

• Head trauma and brain injuries

• Stroke or vascular blockages

• Brain infections such as meningitis and encephalitis

• Brain tumors or cysts

• Prenatal or perinatal oxygen deprivation

• Structural abnormalities in brain development

How Is Epilepsy Diagnosed? (Detection Methods)

The most crucial step in diagnosing epilepsy is a detailed clinical history provided by witnesses who observed the seizure, alongside the evaluation of the patient's symptoms by a neurologist. The duration of the seizure, how it started, and the recovery period play a key role in the diagnosis.

Primary diagnostic tools used to detect epilepsy include:

Electroencephalography (EEG)

EEG is the most widely used and fundamental diagnostic tool in epilepsy. The brain's electrical activity is recorded using electrodes placed on the scalp. By identifying abnormal waves during or between seizures, specialists determine the type and origin of the epilepsy.

Magnetic Resonance Imaging (MRI)

A brain MRI provides detailed images of brain tissue. It helps detect underlying structural issues such as tumors, vascular anomalies, cysts, infection scars, or malformations that may cause epilepsy.

Computed Tomography (CT)

CT scans are preferred primarily in emergency settings to rapidly identify post-traumatic bleeding or acute intracranial masses.

Laboratory Tests

Blood tests and metabolic screenings are performed to rule out electrolyte imbalances, infections, or toxic conditions that could trigger seizures.

What Are the Treatment Options for Epilepsy?

The primary goal of epilepsy treatment is to achieve complete seizure freedom or minimize seizure frequency and severity while preserving the patient's quality of life. Treatment is tailored to the individual, the seizure type, and the underlying cause.

Medication (Antiepileptic Drugs)

Antiepileptic drugs (AEDs) are the first-line and most common form of treatment. These medications suppress seizures by regulating the brain's electrical balance. In approximately 70% of patients, seizures can be successfully managed with the appropriate medication and dosage. Taking medications consistently without abrupt discontinuation is vital.

Surgical Treatment

For patients with drug-resistant epilepsy where the seizure focus can be precisely localized to a single operable area of the brain, surgical options may be considered. Surgically removing the epileptogenic zone can help achieve seizure control.

Neuromodulation (Device Therapies)

For patients who are not candidates for resective surgery or who have refractory epilepsy, approaches such as Vagus Nerve Stimulation (VNS) may be used. A small device implanted in the chest area sends electrical pulses to the brain at set intervals to reduce seizure frequency.

Ketogenic Diet

Especially in drug-resistant childhood epilepsies, specialized high-fat, low-carbohydrate dietary therapies managed under the supervision of a specialist physician and clinical dietitian can help control seizures.

First Aid During a Seizure

Proper intervention when encountering someone experiencing a seizure is essential:

• Help the person down to a safe surface and clear away hard or sharp objects.

• Place a soft support (such as a folded jacket or pillow) under their head.

• Loosen tight clothing around the neck (ties, collars, scarves).

• Gently turn the person onto their side (recovery position) to keep the airway clear and allow fluids to drain.

• Do not put anything in their mouth, force their teeth apart, or attempt to give them water.

• Do not restrain the person or attempt to stop their movements by force.

• Time the duration of the seizure.

When Should You See a Doctor?

Anyone experiencing a seizure for the first time should undergo immediate medical evaluation. For individuals diagnosed with epilepsy, regular neurology follow-ups are essential to monitor treatment efficacy.

Emergency medical services (such as 911 or 112) should be contacted immediately if:

• The seizure lasts longer than 5 minutes

• A second seizure occurs before the person regains consciousness

• Breathing difficulties or prolonged unresponsiveness continue after the seizure stops

• The seizure occurs in water (pool, ocean, bathtub)

• A significant head injury or trauma occurs during the seizure

• The individual having the seizure is pregnant or has diabetes
