Most seizures can be significantly reduced or completely stopped with the right combination of medication, lifestyle changes, and sometimes surgery or implanted devices. About half of people with epilepsy become seizure-free on their first medication, and even those who don’t respond to initial treatments still have meaningful options. The path to seizure control looks different for everyone, but understanding what’s available helps you work with your care team toward the best outcome.
Why Seizures Happen and What Stops Them
Seizures occur when groups of brain cells fire electrical signals in an uncontrolled burst. In a healthy brain, there’s a balance between excitatory signals (which activate neurons) and inhibitory signals (which calm them down). When that balance tips too far toward excitation, a seizure results. Every treatment for seizures works by shifting this balance back, either by dampening the overactive signals or by boosting the brain’s natural braking system.
Anti-Seizure Medications
Medication is the first-line treatment for seizures, and it works well for a large number of people. These drugs fall into several categories based on how they calm brain activity. Some stabilize sodium channels, which are the tiny gates that neurons use to fire. By locking these channels in an inactive state, the drugs prevent the rapid, repetitive firing that causes a seizure. Others target calcium channels, which act as pacemakers for rhythmic brain activity. Blocking them stops the slow electrical waves that build into certain seizure types.
A third group boosts a natural brain chemical called GABA, which is the brain’s primary “slow down” signal. These medications work by increasing GABA production, preventing its breakdown, or blocking its removal from the spaces between neurons. Still other drugs reduce the effects of glutamate, the brain’s main excitatory chemical.
Your doctor will choose a specific medication based on your seizure type, age, other medications, and side-effect profile. The goal is always to find the single lowest-effective option first.
What Happens When Medications Don’t Work
If the first medication doesn’t control your seizures, your doctor will typically try a second, either alone or in combination. If two appropriately chosen medications fail to produce sustained seizure freedom, you meet the formal definition of drug-resistant epilepsy set by the International League Against Epilepsy. Roughly one in three people with epilepsy falls into this category.
But “drug-resistant” doesn’t mean untreatable. Research from the ILAE found that among people who tried a third medication, about 24% achieved seizure freedom. Even on a fourth, fifth, or sixth drug, roughly 14 to 15% became seizure-free. In one study of 403 patients who had already failed at least two medications, 31% eventually achieved seizure freedom with further treatment changes. Each new attempt carries a real chance of success, so persistence matters.
The Ketogenic Diet
One of the oldest treatments for epilepsy is a high-fat, very-low-carbohydrate diet that forces the body to burn fat for fuel instead of sugar. This metabolic shift produces molecules called ketones, which appear to have a stabilizing effect on brain activity. Johns Hopkins Medicine, a leading center for this therapy, uses a modified version for adults that resembles the Atkins diet and doesn’t require a hospital stay, fasting, food weighing, or calorie counting.
For children, the process is more structured. Families typically go through a three-day orientation to start the diet and learn how to manage it, followed by clinic visits every one to three months. During this time, you’ll track urine ketone levels, weight, and seizure frequency on a calendar. It’s important not to change seizure medications right away so the diet’s effects can be evaluated on their own. The ketogenic diet is most often used alongside medication, not as a replacement, and it works best under close medical supervision.
Surgery for Seizures
When medications and diet aren’t enough, surgery can be a powerful option for people whose seizures start in an identifiable area of the brain. The most common approach is surgical resection, where the tissue responsible for triggering seizures is removed. This can range from removing a small lesion to removing a larger section of a lobe. More than 85% of people who undergo temporal lobe resection experience a large decrease in seizure frequency afterward, according to Cleveland Clinic data.
A newer, less invasive option is laser thermal therapy, which uses MRI-guided laser probes to destroy the small cluster of nerve cells at the seizure’s origin. Because it doesn’t require open surgery, recovery is typically faster and the procedure carries fewer risks. Both approaches require extensive pre-surgical testing to map exactly where seizures begin and to confirm that removing or disabling that tissue won’t cause significant problems with movement, language, or memory.
Implanted Neuromodulation Devices
For people who aren’t candidates for surgery, or who want an additional layer of control, implanted devices can reduce seizure frequency by delivering electrical pulses to the brain or nervous system. Three FDA-approved options exist, and they differ in how and where they work.
- Vagus nerve stimulation (VNS) uses a small pulse generator implanted in the chest that sends regular electrical signals to the vagus nerve in the neck. It reduced seizures by about 33% in the first year, improving to roughly 54% by year three.
- Responsive neurostimulation (RNS) places a device directly in the skull, connected to electrodes that monitor brain activity in real time. When it detects abnormal patterns, it delivers a targeted pulse to interrupt the seizure before it starts. Seizure reduction averaged 66% in the first year and 68% by year three.
- Deep brain stimulation (DBS) sends programmed electrical pulses from a chest-implanted generator to electrodes placed in the thalamus, a relay center deep in the brain. It achieved about 58% seizure reduction in year one, rising to 64% by year three.
RNS and DBS both outperformed VNS in the first year after implantation, though the differences narrowed over time as VNS results continued to improve. Your neurologist will recommend one over the others based on where your seizures originate and whether they come from one focus or multiple areas.
FDA-Approved CBD for Specific Syndromes
A prescription CBD oral solution is FDA-approved for seizures associated with three specific conditions: Lennox-Gastaut syndrome, Dravet syndrome, and tuberous sclerosis complex, all in patients one year of age and older. This is not the same as over-the-counter CBD products, which are unregulated and have not been proven effective for seizures. The prescription form is a pharmaceutical-grade formulation with established dosing and safety monitoring, including regular liver function testing.
Lifestyle Changes That Reduce Seizures
Medication and procedures do the heavy lifting, but daily habits play a real role in how often seizures break through. Common triggers include sleep deprivation, high stress, flashing or flickering lights, heat illness, high fever, abnormal blood sugar levels (both low and very high), and alcohol use or withdrawal. Triggers vary from person to person, so keeping a seizure diary that tracks sleep, stress, meals, and other variables helps you identify your own patterns over time.
The most important lifestyle factor is medication consistency. Always take your medications as directed, even during periods when you feel well. Skipping doses or stopping medication abruptly is one of the most common reasons for breakthrough seizures. Beyond that, prioritizing seven to nine hours of sleep, managing stress through regular exercise or relaxation techniques, limiting alcohol, and staying hydrated all contribute to a lower seizure threshold.
What to Do During a Seizure
If you’re with someone having a seizure, the CDC recommends these steps: stay calm, stay with the person, and move any nearby objects that could cause injury. If they’re lying down, gently turn them onto their side with their mouth pointing toward the ground to keep the airway clear. Put something soft under their head, remove their glasses, and loosen anything around the neck. Time the seizure from the start.
Equally important is what not to do. Don’t hold the person down or try to restrain their movements. Don’t put anything in their mouth. Don’t attempt mouth-to-mouth breathing during the seizure, as breathing typically resumes on its own. Don’t offer food or water until the person is fully alert.
Call 911 if the seizure lasts longer than five minutes, if a second seizure follows quickly, if the person has trouble breathing or waking afterward, if they’re injured, or if the seizure happens in water. You should also call if it’s the person’s first seizure, if they have diabetes and lose consciousness, or if they’re pregnant.
