Seizure frequency can be reduced through a combination of medication, lifestyle changes, dietary strategies, and in some cases surgery or implanted devices. Most people with epilepsy achieve significant improvement with the right approach, though finding that approach often takes time and adjustment. Here’s what actually works, how well it works, and what each option involves.
Medications: The First Line of Defense
Anti-seizure medications are the starting point for nearly everyone with epilepsy, and they control seizures completely in about two-thirds of people. These drugs work through two main strategies. Some stabilize sodium channels in nerve cells, essentially preventing neurons from firing too rapidly. When a nerve cell fires, sodium channels open and close in a cycle. These medications lock the channels in their “off” position during rapid firing, which stops the runaway electrical activity that causes a seizure.
Other medications boost the activity of GABA, the brain’s primary calming chemical. GABA works by allowing chloride ions to flow into nerve cells, which makes them less likely to fire. By enhancing this natural braking system, these drugs raise the threshold your brain needs to cross before a seizure begins. Some newer medications combine both approaches or target additional pathways.
Finding the right medication often requires patience. Your neurologist may try several options before landing on one that controls your seizures without intolerable side effects. Taking medication consistently, at the same time each day, is one of the simplest and most important things you can do. Missed doses are a common and avoidable seizure trigger.
Avoiding Known Triggers
Certain everyday factors lower your seizure threshold, and managing them can meaningfully reduce how often seizures occur. Sleep deprivation is one of the most potent triggers. Research using brain stimulation and EEG monitoring has shown that the excitability of the frontal cortex progressively increases the longer you stay awake, and only drops back down after recovery sleep. Even one night of poor sleep can be enough to provoke a seizure in someone who is otherwise well controlled.
Alcohol has a complicated relationship with seizures. During active drinking and especially during withdrawal, seizure risk climbs significantly. Even occasional drinking can shift the seizure threshold in susceptible people, despite alcohol’s short-term sedating effects. Stress is another major trigger, though its effects are harder to pin down because stress is constant and variable. The key is recognizing your personal pattern: many people notice warning signs in the hours or days before a seizure, often during periods of high stress or disrupted sleep.
Stress Reduction Techniques
A study presented by the American Academy of Neurology tested whether structured relaxation training could reduce seizures in people whose medications weren’t fully working. Participants who learned progressive muscle relaxation, a method where you systematically tense and then release each muscle group along with controlled breathing, practiced the technique twice daily using an audio recording. On days when they noticed warning signs of an approaching seizure, they added an extra session. All participants continued to have at least four seizures over roughly two months before starting the program, so these were people with difficult-to-control epilepsy. While this isn’t a replacement for medication, building a consistent relaxation practice gives you an additional tool for lowering your baseline excitability.
Dietary Approaches That Work
The ketogenic diet has decades of evidence behind it, particularly for children and adults with drug-resistant epilepsy. This high-fat, very-low-carbohydrate diet forces the brain to use ketone bodies instead of glucose for fuel, which appears to stabilize electrical activity. A 2025 meta-analysis found that children on the ketogenic diet were nearly eight times more likely to achieve a 50% or greater seizure reduction compared to controls, and similarly more likely to achieve a 90% or greater reduction.
The classic ketogenic diet is strict. Every meal is carefully weighed and measured, calories and fluids are restricted, and the ratio of fat to protein and carbohydrates is tightly controlled. It typically requires a hospital stay to initiate, and families often find it difficult to sustain long-term.
The Modified Atkins Diet offers a more practical alternative with comparable results. About 40 to 50 percent of people on this diet see a greater than 50% seizure reduction, and roughly 15% become seizure-free. The key differences that make it easier to follow: there’s no calorie or fluid restriction, proteins are unlimited, foods don’t need to be weighed (though you do track carbohydrate counts), and it can be started at home without fasting. You can eat in restaurants and manage the diet without the precise calculations the classic version demands. For many families, this flexibility makes the difference between sticking with the diet and abandoning it.
CBD as an Add-On Treatment
Pharmaceutical-grade cannabidiol (CBD) is now FDA-approved for certain severe epilepsy syndromes, including Dravet syndrome and Lennox-Gastaut syndrome. Clinical data from an expanded access program showed a median reduction of about 52% in total seizures at 12 weeks, improving to 60% by 48 weeks. For convulsive seizures specifically, the reduction was even larger: 58% at 12 weeks and nearly 64% at 48 weeks. Compared to an external control group, CBD provided a 43% greater seizure reduction.
This is a prescription medication, not the same as over-the-counter CBD products you’d find in a store. The dosing, purity, and formulation matter enormously, and it’s used alongside other anti-seizure medications rather than as a standalone treatment.
Implanted Devices for Drug-Resistant Epilepsy
When medications and diet aren’t enough, neuromodulation devices offer another layer of seizure control. These are surgically implanted systems that deliver electrical stimulation to interrupt or prevent seizure activity.
Vagus nerve stimulation (VNS) is the most established option. A small device implanted under the skin of the chest sends regular electrical pulses to the vagus nerve in the neck, which relays signals to the brain. Many people also carry a magnet that lets them trigger an extra burst of stimulation when they feel a seizure coming on. Seizure reduction tends to improve over time, often taking a year or more to reach its full effect.
Responsive neurostimulation (RNS) takes a more targeted approach. Electrodes placed directly on or within the brain continuously monitor electrical activity and deliver stimulation only when they detect the beginnings of a seizure. In clinical trials, this system produced a 25 to 28% seizure reduction during the initial blinded evaluation period, with improvements continuing over months and years as the device learns each person’s seizure patterns. Neither device typically eliminates seizures entirely, but both can make a meaningful difference when other treatments have fallen short.
Surgery: The Most Effective Option for Some
For people whose seizures consistently originate from one identifiable area of the brain, surgery can be the most effective treatment available. A long-term study published in The Lancet followed hundreds of patients after epilepsy surgery and found that 55% of those who had anterior temporal lobe resection, the most common procedure, were seizure-free at five years. At ten years, about 49% remained seizure-free. Across all surgery types, roughly half of patients were free of disabling seizures for the entire follow-up period, and 40% were completely seizure-free.
These are remarkable numbers for a population that, by definition, had already failed to respond adequately to medication. Surgery isn’t right for everyone. It requires extensive testing to locate the seizure focus precisely and to confirm that removing or disconnecting that tissue won’t cause unacceptable deficits in language, memory, or movement. But for candidates who do qualify, it offers the highest probability of seizure freedom of any available treatment.
What to Do During a Seizure
Reducing seizure frequency is a long-term project, but knowing how to respond when one happens matters just as much. If someone near you has a seizure, stay with them, move away anything they could hit, and gently roll them onto their side with their mouth pointing toward the ground to keep their airway clear. Put something soft under their head. Loosen anything tight around their neck. Do not put anything in their mouth, and do not try to restrain them.
Time the seizure from the start. If it lasts longer than five minutes, call 911. You should also call for emergency help if a second seizure follows quickly, if the person has trouble breathing or waking afterward, if they’re injured, if the seizure happens in water, if they’ve never had a seizure before, or if they’re pregnant.
