Seizure Disorders and Epilepsy
What is Seizure Disorders and Epilepsy?
Seizure disorders are conditions that cause sudden, uncontrolled electrical activity in the brain. This electrical disruption can lead to changes in behavior, movements, feelings, or consciousness. Epilepsy is the most common chronic seizure disorder, defined as having two or more unprovoked seizures.
Seizures happen when nerve cells in the brain send out wrong signals at the wrong time. These bursts of electrical activity can affect part of the brain or the entire brain. Not all seizures look like convulsions. Some people stare blankly, experience confusion, or have temporary muscle twitches.
Around 3.4 million people in the United States live with epilepsy. Many seizure disorders can be managed with medication, lifestyle changes, and monitoring key health markers. Understanding what triggers seizures and keeping your body chemistry balanced can help reduce seizure frequency and severity.
Symptoms
- Temporary confusion or staring spells
- Uncontrolled jerking movements of arms and legs
- Loss of consciousness or awareness
- Sudden falls without apparent cause
- Muscle stiffness or limpness
- Strange sensations like tingling or visual disturbances
- Unusual sounds, smells, or tastes
- Sudden fear, anxiety, or déjà vu
- Lip smacking or chewing movements
- Temporary inability to speak or respond
Some people experience warning signs called auras before a seizure starts. Others have no symptoms between seizures and feel completely normal. Seizure symptoms vary widely depending on which part of the brain is affected and how far the electrical activity spreads.

Causes and risk factors
Seizure disorders have many possible causes. Genetic factors play a role in some types of epilepsy, running in families. Brain injuries from trauma, stroke, or infections like meningitis can damage brain tissue and lead to seizures. Developmental disorders, brain tumors, and abnormal blood vessel formations also increase seizure risk. In about half of all epilepsy cases, doctors cannot identify a specific cause.
Certain metabolic imbalances can trigger seizures or make them worse. Low magnesium levels, called hypomagnesemia, lower the seizure threshold by causing neuromuscular hyperexcitability. Severe magnesium deficiency below 1.0 mg/dL can directly precipitate seizures. Other triggers include lack of sleep, stress, flashing lights, alcohol use, fever, and skipping seizure medications. Hormonal changes during menstruation can also affect seizure patterns in women.
How it's diagnosed
Doctors diagnose seizure disorders through medical history, physical examination, and neurological testing. An electroencephalogram, or EEG, records brain wave patterns and can detect abnormal electrical activity. Brain imaging with MRI or CT scans helps identify structural problems like tumors or scarring. Blood tests play an important role in seizure workups by checking for metabolic causes and electrolyte imbalances.
Rite Aid's testing panel includes serum magnesium, which is checked in seizure evaluations. Low magnesium can trigger seizures or make existing seizure disorders harder to control. Testing magnesium levels is especially important in refractory cases where seizures do not respond well to medication. Regular monitoring helps ensure your body chemistry supports brain health and seizure control.
Treatment options
- Anti-seizure medications prescribed by a neurologist to control electrical activity
- Magnesium supplementation if blood tests show deficiency
- Consistent sleep schedule with 7 to 9 hours nightly
- Stress reduction through meditation, yoga, or counseling
- Avoiding known triggers like alcohol, flashing lights, or missed meals
- Ketogenic diet or modified Atkins diet in some cases
- Regular exercise to support overall brain health
- Seizure diary to track patterns and identify triggers
- Vagus nerve stimulation or brain surgery for medication-resistant epilepsy
- Safety measures like wearing medical alert jewelry

Frequently asked questions
A seizure is a single event of abnormal electrical activity in the brain. Epilepsy is a chronic condition defined as having two or more unprovoked seizures. Anyone can have a seizure from fever, head injury, or low blood sugar. Epilepsy means seizures happen repeatedly without an immediate trigger.
Yes, severe magnesium deficiency can trigger seizures. Magnesium helps regulate nerve and muscle function throughout your body, including your brain. When magnesium drops below 1.0 mg/dL, it lowers your seizure threshold and increases neuromuscular excitability. Checking magnesium levels is part of a thorough seizure workup.
Testing frequency depends on your medications and overall health. Many doctors recommend checking magnesium and other metabolic markers every 6 to 12 months. More frequent testing may be needed if you take medications that affect electrolyte balance or if seizures are poorly controlled. Talk to your neurologist about the right schedule for you.
Common triggers include lack of sleep, stress, flashing lights, alcohol, fever, and skipped medications. Hormonal changes during menstruation can trigger seizures in some women. Low blood sugar, dehydration, and electrolyte imbalances like low magnesium also increase seizure risk. Identifying your personal triggers helps you avoid them.
Some people outgrow certain types of childhood epilepsy. Others become seizure-free with medication and may eventually stop treatment under doctor supervision. About 70% of people with epilepsy can control seizures with medication. Surgery can cure epilepsy in some cases when seizures start in one specific brain area.
Yes, regular exercise is generally safe and beneficial for people with epilepsy. Physical activity supports overall brain health and can help reduce stress, a common seizure trigger. Choose activities appropriate for your seizure type and avoid swimming alone or climbing at heights without supervision. Always talk to your doctor about exercise safety.
Stay calm and time the seizure. Move nearby objects to prevent injury but do not restrain the person. Turn them gently on their side if possible to keep airways clear. Never put anything in their mouth. Call 911 if the seizure lasts more than 5 minutes or if the person is injured.
Yes, diet can play a role in seizure management. The ketogenic diet, high in fats and very low in carbohydrates, helps reduce seizures in some people. Eating regular meals prevents low blood sugar, which can trigger seizures. Ensuring adequate magnesium through leafy greens, nuts, and seeds supports healthy nerve function.
About 30% of people with epilepsy have medication-resistant seizures. Causes include incorrect diagnosis, wrong medication choice, or structural brain abnormalities. Metabolic issues like chronic magnesium deficiency can also make seizures harder to control. Refractory epilepsy may require multiple medications, diet therapy, or surgical options.
Yes, stress is one of the most commonly reported seizure triggers. Stress hormones affect brain chemistry and can lower seizure threshold even in people taking medications. Managing stress through adequate sleep, regular exercise, and relaxation techniques helps reduce seizure frequency. Some people benefit from counseling or cognitive behavioral therapy.
