Seizures can be reduced or controlled through a combination of medication, lifestyle changes, dietary therapy, surgical options, and implanted devices. Most people with epilepsy achieve significant improvement with anti-seizure medications alone, but roughly one in three will need additional approaches. The best strategy depends on seizure type, frequency, and how well you respond to initial treatment.
Avoiding Common Triggers
Not everyone with epilepsy has identifiable triggers, but many people notice patterns that make seizures more likely. The most common triggers include lack of sleep, alcohol use, flashing lights, missed medication doses, and illicit drug use. Stress and menstruation are also frequently reported.
Keeping a seizure journal helps you spot your personal patterns. Each time a seizure happens, note the time, type, duration, and anything unusual from the prior 24 hours: poor sleep, a skipped dose, higher stress, or your point in the menstrual cycle. Over weeks or months, this log often reveals which factors matter most for you, giving you something concrete to manage.
Dietary Approaches
The ketogenic diet, a high-fat, very-low-carbohydrate eating plan, has been used to treat epilepsy for over a century. It works by shifting the brain’s primary fuel source from glucose to molecules called ketones, which appear to stabilize electrical activity in the brain. In a meta-analysis of clinical studies, about 57% of people on the classic ketogenic diet achieved at least a 50% reduction in seizure frequency.
A less restrictive version, the modified Atkins diet, showed a 46% rate of the same benchmark. It allows more protein and doesn’t require weighing food as precisely, making it easier to maintain long-term. Both diets require medical supervision because they change your metabolism significantly and can affect cholesterol, kidney function, and nutrient levels. A dietitian experienced with epilepsy will typically design and monitor your plan.
Rescue Medications for Emergencies
Rescue medications are fast-acting treatments designed to stop a seizure cluster or a seizure lasting longer than usual. They’re meant to be given at home or in public by a caregiver, not just in a hospital. Several options are now available in forms that don’t require an injection.
Nasal spray versions include midazolam (approved for ages 12 and up) and diazepam (approved for ages 6 and up). Midazolam nasal spray reaches its peak concentration in about 15 minutes. If a seizure hasn’t stopped 10 minutes after the first dose, a second spray can be given. Rectal diazepam gel remains the only rescue therapy approved for children as young as 2. In Europe, a form of midazolam placed inside the cheek is approved for infants through age 17, though it isn’t available in the United States.
These medications shouldn’t be used more than once every five days, and no more than five times per month. If you or someone you care for has frequent seizure clusters, having a rescue plan and the right medication on hand can prevent emergency room visits and reduce the risk of prolonged seizures causing harm.
Surgery for Drug-Resistant Epilepsy
When two or more medications fail to control seizures, the condition is considered drug-resistant. For people whose seizures originate in a specific, identifiable area of the brain, surgery to remove that tissue can be remarkably effective. The most studied procedure targets the temporal lobe, the most common origin point for focal seizures.
In a long-term study of 621 patients who had temporal lobe surgery, 73.6% were free from disabling seizures afterward. That rate held up well over time: patients followed for more than 20 years still had seizure-free rates around 65%. The standard approach, which removes a broader section of temporal lobe tissue, produced better results (78.6% seizure freedom) than a more selective technique targeting only deeper structures (67.2%).
Not everyone is a candidate. Surgery works best when imaging clearly shows where seizures start and that area can be removed without damaging critical functions like language or memory. If drug-resistant epilepsy is suspected, referral to a specialized epilepsy surgery center for evaluation is the recommended next step.
Implanted Neurostimulation Devices
For people who aren’t surgical candidates or who continue having seizures after surgery, implanted devices that deliver electrical pulses to the brain or nervous system offer another layer of control.
Vagus Nerve Stimulation (VNS)
A VNS device, implanted under the skin in the chest, sends regular electrical pulses to the vagus nerve in the neck, which relays signals to the brain. It doesn’t stop seizures instantly but gradually reduces their frequency over months. After three months of use, patients typically see a 46% reduction in seizure frequency. The device reaches optimal effectiveness around the six-month mark, with reductions of 50 to 100%. Results continue to improve at the one- and two-year follow-ups. Side effects are generally mild, most commonly hoarseness or a tingling sensation during stimulation.
Responsive Neurostimulation (RNS)
The RNS system takes a different approach. Electrodes placed directly on or within the brain continuously monitor electrical activity and deliver targeted stimulation the moment abnormal patterns begin, essentially interrupting a seizure before it fully develops. In clinical trials, the median seizure reduction was 44% at one year and 53% at two years. Real-world data from individual centers has been even more encouraging, with one cohort showing 57% reduction at one year and 81% at two years. The overall median reduction across about three years of follow-up reached 74.5%.
CBD-Based Medication
A purified form of cannabidiol (CBD) is now an approved prescription medication for certain severe epilepsy syndromes, including Lennox-Gastaut syndrome and Dravet syndrome. These are conditions that typically resist standard treatments and cause frequent, dangerous seizures.
In clinical trials involving 215 patients, those taking CBD saw a median reduction in drop seizures (the type that cause sudden falls) of about 37 to 44%, compared to 17 to 22% for placebo. Sixty percent of patients were rated by their caregivers as at least “slightly improved” overall, and 31% were rated “much improved” or better after 14 weeks. Patients rated as “much improved” had an average seizure reduction of nearly 58%. This medication is taken as an oral liquid and is used alongside other anti-seizure drugs, not as a standalone treatment.
Seizures Linked to the Menstrual Cycle
Some women notice their seizures cluster around specific points in their menstrual cycle, a pattern called catamenial epilepsy. This happens because of natural fluctuations in hormones: estrogen tends to increase brain excitability, while progesterone has a calming effect. When progesterone drops sharply before menstruation, the seizure threshold can fall with it.
Progesterone supplementation during the second half of the menstrual cycle has shown meaningful results. In one study, women who took progesterone from day 15 to day 25 of their cycle, alongside their regular medications, experienced significantly fewer seizures than those on placebo. A separate study using higher-dose progesterone during a similar window found a 54 to 68% monthly reduction in seizure frequency in 72% of participants over three months. Among those who continued for three years, reductions of 62 to 74% were maintained.
Wearable Seizure Detection Devices
Wearable devices that detect seizures and alert caregivers have become increasingly accurate, particularly for the most dangerous seizure type: generalized tonic-clonic seizures (the kind involving full-body convulsions and loss of consciousness). Across three large clinical studies, devices using motion sensors, muscle activity sensors, or combinations of heart rate and motion data detected 90 to 96% of these seizures, with only 0.2 to 0.7 false alarms per day.
Detection of seizures without a tonic-clonic component remains less reliable, with sensitivities ranging from 32 to 90% and significantly higher false alarm rates. These devices are most useful for nighttime monitoring, since seizures during sleep carry a higher risk of going unnoticed. Studies on SUDEP (sudden unexpected death in epilepsy) prevention found that nighttime supervision and monitoring reduced risk in 50% of patients evaluated.
What to Do During a Seizure
If someone near you has a seizure involving convulsions, stay with them and clear away anything nearby that could cause injury. Ease them to the ground if they’re standing, then gently roll them onto one side with their mouth pointing downward to keep the airway clear. Place something soft under their head, remove their glasses, and loosen anything tight around their neck. Time the seizure from the start. If it lasts longer than five minutes, call 911.
Do not put anything in their mouth, try to hold them down, or offer food or water until they are fully alert. Most seizures end on their own within one to three minutes. Afterward, speak calmly and help orient them, as confusion following a seizure is normal and can last several minutes.
