Stress seizures fall into two distinct categories, and stopping them depends on which type you have. Some people have epilepsy where stress lowers the threshold for a seizure to occur. Others have what are called functional seizures (previously known as psychogenic nonepileptic seizures, or PNES), which look and feel like epileptic seizures but aren’t caused by abnormal electrical activity in the brain. They’re a physical reaction of your nervous system to stress, trauma, or pain. The treatment path for each is fundamentally different, so getting the right diagnosis is the critical first step.
Functional Seizures vs. Stress-Triggered Epilepsy
Functional seizures are surprisingly common and are frequently misdiagnosed as epilepsy for years. During a functional seizure, your brain’s electrical activity remains normal. There’s no misfiring of neurons the way there is in epilepsy. Instead, your nervous system essentially overloads in response to a trigger, producing episodes that can include full-body shaking, loss of awareness, rapid side-to-side head movements, out-of-sync limb movements, or eyes-closed unresponsiveness. Episodes often last longer than typical epileptic seizures, sometimes exceeding 10 minutes.
Stress-triggered epileptic seizures, on the other hand, involve genuine abnormal electrical discharges in the brain. Chronic stress raises cortisol levels through your body’s hormonal stress response, and over time this can alter brain chemistry in ways that lower your seizure threshold. Essentially, accumulated stress brings you closer to the point where a seizure fires. Some people with epilepsy also have functional seizures on top of their epileptic ones, which makes diagnosis even more important.
Why a Correct Diagnosis Matters
The gold standard for telling these apart is a video EEG, which records both your brain’s electrical activity and video of your body during an episode. If the EEG shows normal brain activity while you’re having a seizure, the diagnosis is functional seizures. If it shows abnormal electrical patterns, it’s epilepsy.
When video EEG isn’t possible, neurologists can often reach a reliable diagnosis by reviewing smartphone video of a typical episode alongside your medical history and any available EEG data. A 2024 practice guideline published in Neurology confirmed that smartphone recordings reviewed by a specialist allow accurate diagnosis in most cases.
This distinction isn’t academic. Anti-seizure medications, the standard treatment for epilepsy, do not work for functional seizures. Continuing them when the diagnosis is clearly functional seizures has actually been associated with worse outcomes. If you’ve been taking anti-seizure medication without improvement, it’s worth asking your neurologist whether your seizures might be functional rather than epileptic.
Stopping Functional Seizures
Because functional seizures originate from your nervous system’s response to stress and trauma rather than from electrical misfiring, the most effective treatments target the underlying psychological and physiological drivers.
Cognitive Behavioral Therapy
Therapy specifically adapted for functional seizures is the front-line treatment. It helps you identify the emotional and physical triggers that precede episodes, then build new responses to those triggers. In one clinical study, half of patients who completed a course of adapted cognitive behavioral therapy reduced their daily seizure frequency by 50% or more. The therapy typically involves learning to recognize early warning signs in your body, reprocessing traumatic memories that may be fueling episodes, and gradually building confidence that you can interrupt the cycle before a full seizure develops.
Antidepressants as a Bridge
For people who have difficulty engaging with therapy, whether because of low psychological insight or practical barriers, antidepressants can reduce the frequency of functional seizures. Evidence shows that antidepressants alone, and antidepressants combined with therapy, both lead to fewer episodes. They work by stabilizing the neurochemical environment that makes your nervous system reactive to stress. They’re best understood as a complement to therapy rather than a standalone solution.
Reducing Stress-Triggered Epileptic Seizures
If you have epilepsy and stress is a major trigger, your medication regimen stays in place, but layering stress-reduction techniques on top can meaningfully lower seizure frequency.
Mindfulness-Based Therapy
A controlled trial published in Neurology tested mindfulness-based therapy in people with drug-resistant epilepsy. The group practicing mindfulness showed significantly greater reductions in seizure frequency compared to a support-only control group, with a medium to large effect size. They also experienced less depression and anxiety. The program involved structured meditation, body awareness exercises, and techniques to observe stress responses without reacting to them. Participants practiced daily over several weeks, and the benefits appeared to build with consistent use.
Biofeedback Training
Biofeedback teaches you to consciously influence your body’s autonomic responses, things like heart rate and skin conductance that normally operate below awareness. People with epilepsy often show abnormal autonomic function even between seizures, and training this system appears to raise the seizure threshold. In a controlled trial of 40 patients with drug-resistant temporal lobe epilepsy, 45% of those who received biofeedback therapy achieved a greater than 50% reduction in seizures. Brain imaging revealed that the improvement correlated with strengthened connections between the brain’s emotional processing center and its frontal decision-making regions, suggesting biofeedback helps your brain regulate itself more effectively under stress.
Daily Habits That Lower Your Baseline Stress
Regardless of which type of stress seizure you have, your daily stress load acts as a kind of fuel. The more accumulated, unresolved stress you carry, the closer you sit to the threshold where a seizure can occur. This concept, sometimes called allostatic load, means that reducing your baseline stress level creates a wider buffer zone between your everyday state and a seizure.
Sleep is one of the most powerful levers. Sleep deprivation directly increases cortisol and lowers seizure thresholds, so consistent sleep schedules matter more for you than for the average person. Aim for the same bedtime and wake time every day, including weekends.
Regular physical activity reduces cortisol reactivity over time, meaning your body produces a smaller stress hormone spike in response to the same stressor. Even moderate exercise like brisk walking for 30 minutes most days can shift this pattern within weeks.
Caffeine and alcohol both affect seizure thresholds, with alcohol withdrawal being a particularly common trigger. If you notice a pattern between substance use and your episodes, tracking it in a seizure diary can help you and your care team identify modifiable triggers.
What to Do During a Stress Seizure
The first aid guidelines for functional seizures are the same as for epileptic seizures. Keep the person safe from injury. If they’ve fallen, place something soft under their head. Don’t restrain them or try to hold them down. Don’t put anything in their mouth. Stay with them until they’ve recovered. Only move them if they’re in immediate danger from their surroundings.
If you’re the person having seizures and you can sometimes feel an episode building, techniques learned in therapy, like grounding exercises, controlled breathing, or shifting your attention to specific sensory input, can sometimes interrupt the progression. These aren’t guaranteed to work every time, but many people with functional seizures develop the ability to shorten or occasionally prevent episodes as their treatment progresses.
Building a Treatment Plan
The most effective approach combines proper diagnosis with layered interventions. For functional seizures, that typically means therapy as the core treatment, potentially supported by antidepressants, with daily stress management as the foundation. For stress-triggered epileptic seizures, it means optimizing your medication while adding mindfulness, biofeedback, or both.
Progress usually isn’t linear. Many people see a gradual reduction in frequency and intensity over months rather than a sudden stop. Tracking your seizures, including what happened in the hours and days before each one, gives you and your treatment team data to refine your approach over time. The goal isn’t just fewer seizures. It’s building a nervous system that handles stress without tipping into crisis.
