Psychogenic Nonepileptic Seizures (PNES): What Are Pseudoseizures?

What Are Psychogenic Nonepileptic Seizures?

PNES are sudden episodes involving movement, sensation, awareness, emotion, or behavior that resemble epileptic seizures but are not driven by epileptic electrical activity in the brain. They are classified within functional neurological disorder (FND), a condition in which the nervous system’s functioning is disrupted even though the symptoms are not explained by the electrical pattern that defines epilepsy.

The word functional does not mean minor or imaginary. It describes a problem with how brain networks communicate and control attention, movement, emotion, and bodily responses. Researchers continue to study these networks, and modern care uses a biopsychosocial model: biological vulnerability, physical stress, emotional experiences, learned responses, relationships, and the surrounding environment may all contribute.

Why “Pseudoseizures” Is Outdated

Calling an episode a pseudoseizure can unintentionally accuse the person of faking. By definition, PNES are not consciously produced. Intentional symptom production belongs to different diagnoses and should never be assumed merely because an EEG does not show an epileptic seizure. Preferred terms include functional seizures, psychogenic nonepileptic seizures, and functional or dissociative seizures.

PNES Versus Epileptic Seizures

Epileptic seizures result from abnormal, excessive electrical activity in the brain. Functional seizures can look remarkably similar from the outside, but their underlying mechanism is different. That distinction matters because the treatments are not interchangeable.

Antiseizure medication may reduce epileptic seizures, but it does not directly treat PNES. Conversely, psychotherapy and functional-neurological rehabilitation may help PNES but do not replace epilepsy treatment when epilepsy is present. Some people have both epilepsy and functional seizures, which is why a careful specialist evaluation is essential.

No Single Symptom Proves the Diagnosis

Certain patterns may raise suspicion for PNES, including long or fluctuating episodes, tightly closed eyes, side-to-side head movement, out-of-sync limb movements, whole-body shaking with retained awareness, or events linked to overwhelming situations. However, none of these features is a do-it-yourself diagnostic test. Some epileptic seizures can look unusual, and some functional seizures can look highly stereotyped. The brain enjoys ignoring simple checklists, apparently.

What Do PNES Symptoms Look Like?

Functional seizures vary widely. One person may have dramatic shaking; another may become still and unresponsive. Episodes can include:

• Full-body shaking, jerking, trembling, or stiffening
• Collapsing, falling, or sudden loss of muscle control
• Staring, unresponsiveness, or altered awareness
• Eyes-closed episodes or resistance to eye opening
• Changes in breathing, crying, vocalizing, or panic-like sensations
• Numbness, tingling, dizziness, visual changes, or a sense of disconnection
• Memory gaps, confusion, fatigue, headache, or soreness afterward

Some people notice warning signs such as chest tightness, lightheadedness, rising anxiety, a detached feeling, pain, sensory overload, or rapid breathing. Others have little warning. Frequency may range from rare events to multiple episodes in one day, and the pattern can change over time.

What Causes Functional Seizures?

There is rarely one neat cause tied with a bow. PNES may emerge when the nervous system becomes sensitized to internal or external signals and begins producing an automatic seizure-like response. Possible contributors include:

• Acute or chronic stress
• Past trauma, abuse, loss, bullying, or frightening medical experiences
• Anxiety, depression, panic, post-traumatic stress, or dissociation
• Chronic pain, migraine, fatigue, sleep disruption, or physical illness
• Traumatic brain injury or a history of neurological symptoms
• Difficulty recognizing, processing, or communicating emotional and bodily signals
• Family, school, workplace, financial, or relationship strain

Trauma is a risk factor for some people, not a requirement. A person can have PNES without recalling trauma, without meeting criteria for a psychiatric disorder, and without identifying an obvious trigger. Telling someone, “You must be secretly stressed,” is not a diagnosis; it is an excellent way to make the next appointment awkward.

How Are PNES Diagnosed?

Diagnosis begins with a detailed history: what happened before, during, and after the event; how long it lasted; whether awareness changed; what witnesses observed; and whether there were injuries, sleep-related events, medications, heart symptoms, blood-sugar problems, or other possible explanations. A safe smartphone video may help a neurologist evaluate the episode, but nobody should delay first aid or place themselves at risk to record one.

Video-EEG Is the Diagnostic Gold Standard

When feasible, specialists use video-electroencephalogram monitoring, often called video-EEG or VEEG. The video records the person’s behavior while the EEG records electrical activity from the scalp. Capturing a typical event without the epileptic EEG changes expected for that event strongly supports a functional-seizure diagnosis when interpreted by an experienced clinician.

A routine EEG between episodes cannot settle the question by itself. People with epilepsy may have a normal interictal EEG, and some seizure types are difficult to detect on scalp recordings. Doctors may also consider brain imaging, heart monitoring, tilt-table testing, blood tests, sleep evaluation, and other studies to rule out epilepsy, fainting, arrhythmia, metabolic problems, migraine, sleep disorders, or movement disorders.

The Diagnosis Should Be Explained, Not Dropped Like a Plot Twist

A good clinician names the condition clearly, explains the positive evidence supporting it, confirms that the symptoms are real, and outlines a treatment plan. “Your tests are normal, so nothing is wrong” is both inaccurate and unhelpful. A better message is: “These are functional seizures. They are involuntary, they are treatable, and we will work on the nervous-system processes that maintain them.”

How Are Psychogenic Nonepileptic Seizures Treated?

Treatment is individualized, but the strongest plans usually combine education, psychological treatment, management of related conditions, and continued neurological follow-up. Current clinical guidance supports psychological interventions because they may reduce episode frequency and improve quality of life, anxiety, and daily functioning.

Psychotherapy and Skills-Based Treatment

Cognitive behavioral therapy (CBT) is among the most studied approaches. It may help patients recognize early warning signs, understand links among thoughts, emotions, physical sensations, and behavior, and practice grounding, paced breathing, attention-shifting, problem-solving, and healthier responses to stress. Other approaches may include neurobehavioral therapy, psychoeducation, trauma-focused treatment when appropriate, mindfulness-based strategies, motivational interviewing, or family-based therapy for children and teens.

Treating Related Health Problems

Depression, anxiety, PTSD, sleep problems, migraine, chronic pain, substance use, and other conditions deserve treatment in their own right. Medication may be prescribed for those conditions, but there is no medication that specifically switches off PNES. Physical therapy, occupational therapy, or speech therapy may be useful when functional seizures occur alongside weakness, gait problems, tremor, speech symptoms, or other FND features.

What About Antiseizure Medication?

Antiseizure drugs should not be used solely to treat functional seizures. When epilepsy has been reasonably excluded and there is no other reason for the medication, a clinician may recommend tapering it. Patients should never stop antiseizure medicine abruptly or without medical supervision, especially when the diagnosis remains uncertain or epilepsy also exists.

What Should You Do During an Episode?

For a person with an established PNES diagnosis, follow the individualized seizure action plan created with the care team. In general:

• Stay calm and note when the episode begins.
• Protect the person from traffic, sharp objects, heights, and hard surfaces.
• Do not restrain movements and do not place anything in the mouth.
• Reduce noise, crowds, and intense questioning.
• Use brief, calm reassurance and allow time to recover.
• Afterward, help the person reorient and review any agreed coping steps.

Seek emergency help for a first or unknown event, serious injury, blue or difficult breathing, pregnancy, an episode in water, repeated events without recovery, or an event lasting more than five minutes when epilepsy has not been confidently excluded. When in doubt, safety wins.

What Living With PNES Can Feel Like: Composite Experiences

The following examples are fictional composites based on common clinical themes. They are not quotations or histories from specific patients.

Jordan: Years in Diagnostic Limbo

Jordan’s first event happened at work. Coworkers saw shaking and unresponsiveness, an ambulance arrived, and the emergency department treated the episode as a possible epileptic seizure. That response was reasonable because nobody yet knew what was happening. The difficulty came later. Several routine EEGs were normal, medication caused fatigue, and the episodes continued. Jordan began avoiding public transportation, exercise, and social events for fear of collapsing. Every new appointment seemed to restart the same conversation from page one.

Eventually, an epilepsy-monitoring unit captured Jordan’s typical episode on video-EEG. The neurologist explained that the event was a functional seizure, not an epileptic discharge. Relief and anger arrived together: relief that there was an explanation, anger that it had taken so long. The diagnosis did not instantly stop the episodes, but it changed the map. Jordan could taper unnecessary medication under supervision, start targeted therapy, and build a practical action plan with family and coworkers.

Elena: When the Diagnosis Sounds Like Dismissal

Elena heard the phrase “psychogenic seizure” and thought the clinician was saying, “This is all in your head.” She had never chosen to fall, shake, or lose time. She left the appointment embarrassed and did not schedule therapy. Months later, a different specialist used clearer language: the symptoms were real, the attacks were involuntary, and functional brain networks could produce physical events without epileptic electrical activity. Therapy was not punishment for having emotions; it was treatment for a nervous system caught in an automatic pattern.

That explanation mattered. Elena began noticing a sequence before some attacks: poor sleep, neck pain, rapid breathing, tunnel vision, then disconnection. With practice, she sometimes interrupted the sequence using grounding, slower exhalation, and attention to her surroundings. Not every episode stopped, but fear decreased. Her family also learned to protect her quietly instead of crowding around, shouting questions, and turning each event into a five-alarm family meeting.

Marcus: Recovery That Is Bigger Than an Episode Count

Marcus expected treatment to work like an antibiotic: take the prescribed steps, wait a week, and declare victory. PNES recovery was less tidy. Some months brought fewer attacks; stressful periods brought temporary setbacks. Therapy addressed panic, grief, and avoidance, while physical activity was rebuilt gradually. Marcus kept a brief log of warning signs and recovery time rather than recording every sensation like a nervous-system accountant.

Progress showed up in several forms. He returned to classes part time, slept more regularly, stopped making unnecessary emergency visits, and felt less ashamed when symptoms occurred. Family sessions helped relatives support independence instead of treating him as breakable glass. Eventually, episodes became shorter and less frequent. The important lesson was that recovery did not require proving the events were “real enough.” It required understanding the diagnosis, treating the whole person, and practicing skills until the brain learned safer patterns.

Conclusion

Psychogenic nonepileptic seizures are real, involuntary events at the intersection of neurology, mental health, and nervous-system regulation. They are not epileptic seizures, but they are not fake seizures either. The outdated term pseudoseizures obscures that distinction and can deepen stigma.

Accurate diagnosisideally through expert assessment and video-EEG capture of a typical eventopens the door to appropriate care. Education, respectful communication, psychotherapy, treatment of coexisting conditions, family support, and a personalized action plan can improve both symptoms and daily life. Recovery may be gradual and occasionally zigzag like a shopping cart with one stubborn wheel, but meaningful improvement is possible.

If seizure-like episodes are new, changing, or not yet diagnosed, seek evaluation from a neurologist or epilepsy specialist. Anyone experiencing suicidal thoughts or an immediate mental health crisis in the United States can call or text 988 for confidential support.
