Seizures can be a frightening experience, both for the individual experiencing them and for those witnessing them. Accurate diagnosis and appropriate care are crucial for managing seizures and improving the quality of life for those affected. This guide provides a detailed overview of seizure diagnosis methods and the comprehensive care strategies available.
Diagnosing Seizures: Identifying the Cause
After someone experiences a seizure, healthcare professionals focus on understanding the event and determining the likelihood of future occurrences. Diagnosis involves a thorough review of symptoms, medical history, and a physical examination. Several tests may be conducted to pinpoint the cause of the seizure and assess the risk of recurrence.
Neurological Examination
A neurological exam is a fundamental step in seizure diagnosis. This assessment evaluates various aspects of neurological function, including behavior, motor skills, and cognitive function. By observing these areas, healthcare professionals can gain insights into how the brain is working and identify any potential neurological issues.
Blood Tests
Blood tests are often performed to gather additional information. These tests can reveal important details, such as blood sugar levels, which can sometimes contribute to seizures. They can also detect signs of infections or genetic conditions that might be underlying causes. Electrolyte levels, the salts in the body that manage fluid balance, are also checked.
Spinal Tap (Lumbar Puncture)
In some cases, a spinal tap, also known as a lumbar puncture, may be necessary. This procedure involves collecting a sample of cerebrospinal fluid from the spine. Analyzing this fluid can help determine if an infection is the cause of the seizure.
Electroencephalogram (EEG)
An electroencephalogram (EEG) is a key diagnostic tool for seizures. This test measures the electrical activity of the brain using electrodes placed on the scalp.

The EEG recording displays brain activity as wavy lines, allowing doctors to identify abnormal patterns that may indicate a predisposition to seizures or confirm the presence of epilepsy. EEG testing can also help rule out other conditions that mimic seizure symptoms. EEGs can be performed in a clinic, at home overnight, or during extended monitoring in a hospital setting.
High-Density EEG
For a more detailed assessment of brain electrical activity, a high-density EEG may be utilized.

This advanced EEG technique uses a larger number of electrodes for a more precise recording and localization of seizure activity. Electrodes are attached to the scalp, sometimes using an elastic cap, and connected to the EEG machine.
Imaging Tests: Visualizing the Brain
Imaging tests play a critical role in seizure diagnosis, providing detailed views of the brain’s structure.
MRI (Magnetic Resonance Imaging)
MRI scans utilize strong magnets and radio waves to create detailed images of the brain. An MRI can reveal structural abnormalities in the brain that might be causing seizures, such as lesions, malformations, or tumors.
CT Scan (Computed Tomography)
A CT scan uses X-rays to generate cross-sectional images of the brain.

CT scans are useful for detecting changes in the brain that could lead to seizures, including tumors, bleeding, and cysts. They are often used in emergency situations for rapid assessment.
PET (Positron Emission Tomography) Scan
A PET scan uses a small amount of radioactive material to highlight active areas of the brain. This can help identify brain regions that are functioning abnormally and potentially contributing to seizures.
SPECT (Single-Photon Emission Computerized Tomography) Scan
SPECT scans, similar to PET scans, use radioactive material to create detailed 3D maps of blood flow in the brain.

SPECT is particularly useful for pinpointing the seizure location by measuring blood flow during and between seizures. Subtraction ictal SPECT coregistered to MRI (SISCOM) is a specialized SPECT technique that combines SPECT and MRI results for even greater accuracy in localizing seizure onset zones.
Comprehensive Seizure Care and Treatment Options
Seizure care goes beyond just diagnosis and extends to various treatment strategies aimed at controlling seizures and improving the patient’s overall well-being. Treatment approaches are tailored to the individual and may include medication, dietary changes, surgery, and electrical stimulation therapies.
Medications: Antiseizure Drugs
Medication is often the first line of treatment for seizures. Antiseizure medications are designed to reduce the frequency and severity of seizures. There are numerous types of antiseizure drugs available, and finding the right one and the optimal dosage can sometimes require time and adjustments.
Common side effects of antiseizure medications can include weight changes, dizziness, fatigue, and mood alterations. While rare, more serious side effects such as liver or bone marrow damage are possible. Healthcare professionals carefully consider the individual’s seizure type, frequency, age, and other health conditions when prescribing antiseizure medication. They also review other medications the patient is taking to prevent potential drug interactions.
Dietary Therapy: Ketogenic Diet and Alternatives
Dietary therapy, particularly the ketogenic diet, has proven effective in managing seizures, especially in children with epilepsy. The ketogenic diet is a high-fat, very low-carbohydrate diet that alters the body’s metabolism. While effective, it is restrictive and requires careful monitoring by a healthcare professional and dietitian.
Alternative, less restrictive high-fat, low-carbohydrate diets, such as the low glycemic index and Atkins diets, are also being explored for seizure management, although their effectiveness may be less pronounced than the ketogenic diet.
Surgery: When Medications Are Not Enough
When seizures are not adequately controlled with at least two antiseizure medications, surgery may be considered. Surgery is most effective for individuals whose seizures originate from a specific, localized area in the brain. Surgical options include:
- Lobectomy: Removal of the brain lobe where seizures originate.
- Thermal Ablation (Laser Interstitial Thermal Therapy): A minimally invasive procedure using focused laser energy to destroy seizure-causing brain cells.
- Multiple Subpial Transection: Creating cuts in brain tissue to disrupt seizure spread, often used when the seizure origin cannot be safely removed.
- Corpus Callosotomy: Severing the connections between the brain’s hemispheres to reduce the severity of seizures that spread from one side to the other.
- Hemispherotomy: Disconnecting one hemisphere of the brain, a radical procedure reserved for severe, medication-resistant seizures affecting only one side of the brain.
Electrical Stimulation: Neuromodulation Therapies
Electrical stimulation devices offer alternative treatment options, particularly when surgery to remove the seizure focus is not feasible. These devices work in conjunction with antiseizure medications to reduce seizure frequency.
- Vagus Nerve Stimulation (VNS): A device implanted under the skin stimulates the vagus nerve, sending signals to the brain to reduce seizure activity.
