Epilepsy

Epilepsy is a neurological condition that affects the brain’s electrical activity and can cause repeated seizures. Seizures can take many forms, from brief periods of staring or confusion to involuntary movements and loss of consciousness. Because epilepsy and seizures vary greatly from person to person, accurate diagnosis and personalised treatment are important for reducing risks and supporting everyday life.

An epileptic seizure may be frightening for the person experiencing it and for those around them. However, many people achieve good seizure control with appropriate epilepsy medicine, specialist follow-up, and practical lifestyle adjustments.

Understanding the symptoms of epilepsy, its possible causes, and available treatment options is an important first step towards living safely and confidently with the condition.

What is Epilepsy?

Epilepsy is a chronic neurological disorder in which a person has a tendency to experience recurrent unprovoked seizures. A seizure happens when there is a sudden disruption in the brain’s normal electrical activity. Depending on the area of the brain involved, this may affect consciousness, movement, sensation, behaviour, emotions, memory, or bodily functions.

Having one seizure does not always mean that a person has epilepsy. A seizure may occur in connection with fever, low blood sugar, alcohol withdrawal, certain medicines, head injury, or another acute medical problem. Epilepsy diagnosis generally involves assessing whether seizures are recurrent and whether there is a continuing risk of further unprovoked seizures.

The condition can begin at any age. Some forms develop during childhood, while others appear after brain injury, stroke, infection, or another neurological condition later in life. In many cases, no single cause can be identified.

Symptoms of Epilepsy

The symptoms of epilepsy depend on the type of seizure, the part of the brain where it begins, and how seizure activity spreads. Some seizures are obvious to others, while others are subtle and may be mistaken for daydreaming, panic attacks, fainting, sleep problems, or changes in behaviour.

A person may experience the same seizure pattern repeatedly, although symptoms can also change over time. Sleep deprivation, illness, stress, missed medication, alcohol, hormonal changes, and other epilepsy triggers may increase seizure risk in some people.

Common Seizure Symptoms

Seizure symptoms can occur before, during, and after an episode. Common symptoms include:

• Brief loss of awareness or reduced responsiveness

• Staring into space and not responding to conversation

• Sudden confusion or memory loss

• Repetitive movements, such as lip-smacking, chewing, swallowing, rubbing the hands, or picking at clothing

• Jerking movements of one limb, one side of the body, or the whole body

• Sudden body stiffening

• A sudden fall or loss of muscle tone

• Tingling, numbness, unusual smells, tastes, sounds, or visual changes

• Sudden fear, anxiety, déjà vu, or an unfamiliar feeling

• Loss of bladder control during some severe seizures

• Tiredness, headache, muscle soreness, or confusion after the seizure

A tonic clonic seizure usually causes loss of consciousness, stiffening of the body, and then rhythmic jerking of the limbs. Breathing may appear irregular, and the person may be confused or deeply tired during recovery.

An absence seizure, previously called a petit mal seizure, is usually brief. The person may stare, blink rapidly, or make small movements and then return to their activity without realising that a seizure occurred. Absence seizures are more common in children but can occur at other ages.

Auras: Warning Signs of a Seizure

Some people have an aura before a larger seizure. An aura is a focal seizure in which awareness remains intact, but the person experiences a sudden change in sensation, emotion, or perception.

Possible aura symptoms include:

• A rising feeling in the stomach

• Sudden fear or panic without an obvious reason

• Déjà vu or a feeling that familiar surroundings are unfamiliar

• Strange tastes, smells, sounds, or visual experiences

• Tingling or numbness in part of the body

• Dizziness or nausea

• A feeling of detachment from surroundings

Recognising auras can help a person move away from hazards, sit or lie down safely, alert someone nearby, or follow an individual seizure-action plan.

When to Seek Immediate Medical Attention

Most seizures stop on their own within a few minutes, but some require urgent medical care. Status epilepticus is a medical emergency in which a seizure lasts too long or seizures occur repeatedly without the person regaining full consciousness between them.

Emergency medical attention is needed if:

• A seizure lasts five minutes or longer

• Another seizure begins before the person recovers

• The person has trouble breathing or does not wake as expected

• The seizure occurs in water

• The person is injured during the seizure

• The person is pregnant

• The person has diabetes or another serious medical condition

• It is the person’s first known seizure

During a seizure, move nearby hazards away, place something soft under the person’s head if possible, and gently turn them onto their side after the movements stop or when it can be done safely. Do not restrain the person, do not put anything in their mouth, and do not offer food, drink, or medication until they are fully awake.

Types of Epilepsy and Seizures

Types of epilepsy are classified according to where seizure activity begins, how it spreads, and whether a cause or specific epilepsy syndrome can be identified. Correct classification helps guide treatment for epilepsy and the selection of epilepsy medicine.

Focal epilepsy begins in one area of the brain. A focal seizure may occur with retained awareness or impaired awareness. It can cause unusual sensations, emotional changes, repetitive movements, changes in behaviour, or confusion.

Generalized epilepsy involves seizure activity affecting both sides of the brain from the beginning. Generalized seizures may include absence seizures, tonic clonic seizures, myoclonic seizures, tonic seizures, and atonic seizures.

Common seizure types include:

• Focal aware seizures: The person remains aware but may experience sensory, emotional, or movement symptoms.

• Focal impaired-awareness seizures: Awareness is reduced, and the person may stare, appear confused, or repeat automatic movements.

• Tonic clonic seizures: Consciousness is usually lost, followed by stiffening and rhythmic jerking.

• Absence seizures: Brief periods of reduced awareness, commonly presenting as staring.

• Myoclonic seizures: Sudden, brief muscle jerks, often in the arms or shoulders.

• Atonic seizures: Sudden loss of muscle tone that can cause the head to drop or the person to fall.

• Tonic seizures: Sudden stiffening of the muscles, sometimes leading to falls.

Some people have more than one seizure type. A detailed account from a witness, together with EEG and imaging tests, can help a neurologist identify the type of epilepsy.

Causes and Risk Factors of Epilepsy

The causes of epilepsy can be structural, genetic, infectious, metabolic, immune-related, or unknown. In many people, especially when seizures begin in childhood or early adulthood, routine testing may not identify one clear cause.

Possible causes of epilepsy include:

• Brain injury before, during, or shortly after birth

• Traumatic head injury

• Stroke or reduced blood flow to the brain (carotid artery stenosis)

• Brain tumors and other structural brain changes

• Infections such as meningitis or encephalitis

• Developmental conditions affecting the brain

• Autoimmune disorders involving the nervous system

• Metabolic conditions

• Previous prolonged seizures in childhood

• Genetic epilepsy syndromes

Genetic epilepsy may result from an inherited genetic factor, a new genetic change, or several genes that increase susceptibility to seizures. A family history of epilepsy can increase risk, but it does not mean that every family member will develop the condition.

The risk of epilepsy may also rise after severe head injury, stroke, serious brain infection, or certain developmental disorders. However, most people with these risk factors do not develop epilepsy.

Diagnosing Epilepsy

Epilepsy diagnosis begins with a detailed medical history. The neurologist may ask the person and anyone who witnessed the event about what happened before, during, and after the seizure. A video of the episode, when safely available, may provide useful information because the person may not remember the seizure clearly.

Tests used during epilepsy diagnosis may include:

• A neurological examination

• Blood tests to identify metabolic, infectious, or other possible causes

• Electroencephalography, known as EEG, which records electrical brain activity

• Magnetic resonance imaging, or MRI, to examine brain structure

• Computed tomography, or CT, in urgent or selected situations

• Video EEG monitoring to record seizures and brain activity together

• Genetic testing in selected cases, especially where genetic epilepsy is suspected

A normal EEG does not rule out epilepsy, because unusual electrical activity may not occur during the recording. Likewise, an MRI may be normal even when a person has epilepsy. Diagnosis depends on the full clinical picture rather than one test alone.

Treatment Options for Epilepsy

Treatment for epilepsy aims to prevent or reduce seizures while minimising treatment side effects. The best plan depends on seizure type, epilepsy type, underlying cause, age, other health conditions, medication use, lifestyle needs, and pregnancy plans.

Epilepsy Medicine

Epilepsy medicine, also known as antiseizure medication, is the main treatment for many people. These medicines help reduce abnormal electrical activity in the brain and can provide good seizure control when they are correctly matched to the seizure type.

Important principles of epilepsy medicine include:

• Taking medication consistently at the prescribed time

• Not stopping treatment suddenly without medical advice

• Reporting side effects, new symptoms, or breakthrough seizures

• Reviewing interactions with other prescription medicines, supplements, and alcohol

• Discussing contraception and pregnancy plans before making changes

• Attending regular follow-up appointments

Some people achieve seizure control with one medication. Others may need a different medicine or a combination of treatments. If seizures continue despite appropriate medication trials, further evaluation by an epilepsy specialist may be needed.

Other Treatment Approaches

When medicine alone does not control seizures, additional options may be considered. These treatments are selected carefully after detailed assessment of seizure type, brain imaging, EEG findings, and overall health.

Possible options include:

• Epilepsy surgery: Removal or disconnection of the brain area responsible for seizures in carefully selected patients.

• Vagus nerve stimulation: A device that sends electrical signals through the vagus nerve.

• Responsive neurostimulation: A device that detects abnormal electrical activity and provides targeted stimulation.

• Deep brain stimulation: Electrical stimulation of specific brain regions for selected treatment-resistant cases.

• Ketogenic or modified diets: Supervised dietary treatment, used more often in epilepsy in children but sometimes considered for adults.

• Treatment for an underlying cause: For example, treating a structural, immune-related, or metabolic condition when identified.

Living with Epilepsy

Living with epilepsy often involves medication, regular specialist care, practical safety planning, and support from family, friends, school, or work. The aim is not only to reduce seizures, but also to help people maintain independence, relationships, education, employment, and quality of life.

Epilepsy triggers differ between individuals. Some people notice a link between seizures and missed medication, poor sleep, stress, alcohol, dehydration, illness, flashing lights, or hormonal changes. Others do not identify a clear trigger.

Helpful approaches to living with epilepsy include:

• Taking medication consistently

• Keeping a seizure diary

• Maintaining regular sleep and meals

• Limiting or avoiding known personal triggers

• Learning seizure first aid and teaching it to trusted people

• Using medical identification when appropriate

• Taking care around water, heights, hot surfaces, and machinery

• Seeking epilepsy support for emotional, social, educational, or workplace concerns

• Discussing mental health symptoms with the clinical team

Anxiety, depression, stigma, and fear of having a seizure in public can affect people with epilepsy. Psychological support and patient-support resources can help individuals and families manage these challenges.

Epilepsy and Special Considerations

Epilepsy can affect important life stages and daily activities differently, so care plans should be adapted to factors such as pregnancy, driving, age, overall health, and the person’s individual seizure type and treatment needs.

Epilepsy and Pregnancy

Epilepsy and pregnancy require specialist planning before conception whenever possible. Many people with epilepsy have healthy pregnancies, but seizure control and epilepsy medicine should be reviewed with a neurologist and obstetric team before pregnancy or as early as possible once pregnancy is confirmed.

Stopping medication without medical advice can increase the risk of seizures. Treatment decisions aim to balance good seizure control with the safest medication plan for pregnancy. Folic acid supplementation and closer monitoring of medication levels may be recommended according to individual needs.

Epilepsy and Driving

Epilepsy and driving require careful consideration because a seizure while driving can put the person and others at risk. Driving regulations vary by country and may depend on seizure type, seizure-free period, awareness during episodes, and medical assessment.

Anyone who has had a seizure should discuss driving with their neurologist and follow applicable licensing and reporting rules. Temporary restrictions can be difficult, but transport planning and workplace support can help people maintain independence.

Epilepsy in Children

Epilepsy in children may present differently from epilepsy in adults. Brief absence seizures can be mistaken for daydreaming or attention difficulties, while other seizure types may involve sudden falls, unusual movements, or changes in awareness.

Children with recurrent unexplained staring episodes, falls, involuntary movements, or loss of awareness should be assessed by a pediatric neurologist. Treatment plans should consider development, learning, sleep, behaviour, family routines, and the child’s specific epilepsy type.

Epilepsy in Older Adults

Epilepsy can develop later in life. In older adults, focal seizures may be subtle and may resemble confusion, memory problems, fainting, or temporary behavioural changes.

Stroke is a common cause of new-onset epilepsy in older adults. Medication choice should account for other health conditions, kidney and liver function, fall risk, and possible interactions with medicines used for heart disease, diabetes, blood thinning, or other conditions.

Potential Complications of Epilepsy

Epilepsy complications can arise from seizures, medication side effects, injuries, and the wider effect of seizure-related restrictions on daily life. Risks vary between individuals and often decrease when seizures are well controlled.

Possible epilepsy complications include:

• Falls, burns, drowning, and injuries during a seizure

• Prolonged seizures and status epilepticus

• Anxiety, depression, or social isolation

• Problems with memory, concentration, or sleep

• Restrictions affecting driving, work, education, and independent living

• Side effects from epilepsy medicine

• Pregnancy-related concerns requiring specialist care

• Sudden unexpected death in epilepsy, known as SUDEP, which is uncommon but is more closely associated with uncontrolled tonic clonic seizures

Regular neurological follow-up, adherence to treatment, and a clear safety plan can help reduce avoidable risks.

Research and Advancements in Epilepsy Treatment

Epilepsy research continues to improve understanding of seizure networks, genetic epilepsy, advanced brain imaging, surgical planning, and individual treatment response. Improved EEG monitoring, high-resolution MRI, genetic testing, and neurostimulation techniques are helping clinicians identify seizure types more accurately and offer more personalised treatment.

Current research also examines new epilepsy medicines, improved methods of seizure prediction, immune-related epilepsy, and treatments for people whose seizures do not respond adequately to standard medicine. These advances may provide additional options for treatment-resistant epilepsy in the future.

Comprehensive Epilepsy Care at Medical Park

Medical Park Hospitals provide comprehensive epilepsy care in Turkey through Neurology services supported by EEG assessment, advanced imaging, laboratory testing, and specialist consultation. A detailed evaluation considers seizure symptoms, medical history, imaging findings, electrical brain activity, and potential underlying causes.

Treatment for epilepsy is planned individually and may include epilepsy medicine, regular monitoring, lifestyle guidance, and counselling on epilepsy and pregnancy, epilepsy and driving, school, work, and daily safety. Pediatric Neurology services can support epilepsy in children, while patients with complex medical needs may benefit from coordinated care involving additional specialists.

For people with difficult-to-control seizures, Medical Park can assess whether more advanced diagnostic monitoring, epilepsy surgery evaluation, dietary therapy, or neurostimulation approaches may be appropriate. The goal is to improve seizure control while supporting safety, independence, and quality of life for people living with epilepsy.
