Epilepsy Across the Lifespan – Epilepsy: The Untold Side

Living with epilepsy over time

Epilepsy is not static. Seizure types, syndromes, treatment priorities, independence, cognition, reproductive health, work, bone health and other medical conditions can all change across a lifetime. Good epilepsy care should change with them.

Key point: age alone does not determine epilepsy care. NICE recommends individualising treatment according to age, seizure type, epilepsy syndrome, comorbidities, reproductive considerations, medicines, personal circumstances and the person’s own priorities.

Epilepsy can begin at any age

Some epilepsies begin in infancy or childhood, others emerge during adolescence or adult life, and new-onset epilepsy is also common in older age. The likely causes, seizure patterns and associated conditions are not the same at every stage.

Age at onset can help clinicians recognise an epilepsy syndrome, but it does not by itself determine prognosis.

Childhood: development matters as much as seizure count

In childhood, epilepsy care may need to consider language, learning, behaviour, sleep, development, school participation and the effects of both seizures and treatment on a developing brain.

Some childhood syndromes are self-limited and remit with age. Others persist, evolve into another recognised syndrome or are associated with developmental and epileptic encephalopathy.

A syndrome can evolve over time

An epilepsy syndrome is defined by a characteristic combination of seizure types, EEG findings, age at onset and other clinical features. Those features can change with age.

A seizure type may disappear while another becomes more prominent. EEG patterns may change. A syndrome diagnosed in childhood may look different by adolescence or adulthood.

Adolescence brings more than a service change

Adolescence can bring changes in sleep, medication responsibility, social life, education, alcohol exposure, reproductive health, driving expectations and independence.

NICE specifically recommends discussing daily living, medication adherence, mood, memory, education or work, independent living, cognition, alcohol and drugs, safety, SUDEP, reproductive health, sleep, disclosure and stigma during transition to adult services.

Transition should be planned, not abrupt

NICE recommends involving young people in planning the move from children’s to adult epilepsy services and tailoring transition to the individual.

For young people with uncontrolled seizures, learning disabilities or complex health and social needs, planning should begin early. Paediatric and adult teams should jointly review the diagnosis and management plan.

Information should be provided in an accessible form, repeated when needed and checked for understanding.

Puberty and hormones can alter seizure patterns

Hormonal changes around puberty may coincide with changes in seizure frequency or the emergence of some age-related epilepsy syndromes.

Not every change during puberty is caused by hormones; sleep disruption, growth, adherence and changes in routine may also contribute.

Young adulthood often shifts the practical risks

For many people, young adulthood is when epilepsy begins to affect decisions about driving, employment, relationships, contraception, pregnancy planning, living independently and travel.

Even when seizure frequency is unchanged, the consequences of an unpredictable seizure can change because the person’s responsibilities and environment have changed.

Medication choices can have lifelong consequences

NICE recommends individualised antiseizure medication treatment that takes account of age, sex, seizure type, syndrome, other medicines, comorbidities, education, employment, likelihood of pregnancy, driving, alcohol use and travel.

A medicine that was reasonable at one life stage may need reviewing later because of pregnancy plans, side effects, bone health, interactions, kidney or liver function, or new comorbidities.

Reproductive health should not begin with pregnancy

NICE recommends age-appropriate information for women and girls about contraception, folic acid, conception, pregnancy, breastfeeding, caring for children and menopause.

Current UK safety measures also affect the use of sodium valproate in both males and females younger than 55 and the use of topiramate in women and girls of childbearing potential.

These are treatment-planning issues, not reasons to stop medication without specialist advice.

Pregnancy changes monitoring as well as medication decisions

Pregnancy can alter the blood levels of some antiseizure medicines, and seizure control may change in some people. Pregnancy care therefore needs coordination between epilepsy and maternity services when appropriate.

The balance is individual: uncontrolled seizures can carry risks, while some medicines carry fetal risks. Treatment decisions should be planned rather than made by abruptly stopping medication.

Parenthood can change sleep and seizure risk

Caring for a baby or young child can introduce sleep deprivation, disrupted medication routines and new safety considerations.

A care plan may need to cover night-time support, safe feeding or bathing arrangements, medication timing and what another adult should do if a seizure happens while the person is caring for a child.

Work and epilepsy can change with age

Employment needs can shift as seizure control, medication side effects, cognition and job responsibilities change. A role that was safe at one stage may need new adjustments later — or restrictions may be reduced if seizure control improves.

Risk assessment should be based on the actual job and seizure pattern, not the diagnosis alone.

Driving status can change more than once

Driving eligibility depends on seizure history, seizure type, licensing rules and treatment circumstances. Someone may lose, regain and later need to surrender a licence again if their clinical situation changes.

Cognition deserves repeated review

Memory, attention, processing speed and executive function can be affected by the epilepsy itself, underlying brain disorder, mood, sleep, medication burden and seizure frequency.

Cognitive difficulty is not necessarily fixed. It may improve, worsen or change in character over time, so new problems should not automatically be attributed to longstanding epilepsy.

Mental health can change across life stages

Anxiety, depression, stigma and loss of independence can affect people at any age, but the pressures may differ between school, university, work, parenting, unemployment, retirement and later life.

NICE includes psychological, neurobehavioural, cognitive and developmental comorbidities within epilepsy care rather than treating them as unrelated extras.

Bone health becomes increasingly important

Fracture risk reflects several interacting factors: falls and seizures, age, menopause, mobility, nutrition and long-term exposure to some antiseizure medicines.

NICE notes that long-term use of medicines including carbamazepine, phenytoin, primidone and sodium valproate is associated with reduced bone mineral density and osteomalacia, and recommends considering vitamin D and calcium supplementation for people at risk.

Midlife may introduce new interactions

By midlife, people may be taking medicines for blood pressure, pain, mood, diabetes, cardiovascular disease or other conditions. Drug interactions and cumulative side effects can become more important even if the epilepsy itself has been stable for years.

Medication review should therefore consider the whole prescription list rather than antiseizure medicines in isolation.

Menopause belongs in epilepsy review

NICE specifically includes menopause among the topics that should be reviewed with women and girls with epilepsy over time.

Menopause can coincide with changes in sleep, bone health, cardiovascular risk and use of hormone replacement therapy. Any interaction between HRT and antiseizure medication should be checked individually rather than assumed.

New-onset epilepsy in older age is different from ageing with epilepsy

An older adult may have lived with epilepsy for decades, or may develop seizures for the first time in later life. Those are different clinical situations.

In later-onset epilepsy, acquired causes such as cerebrovascular disease, brain tumours, trauma and neurodegenerative disease become increasingly relevant.

Older adults often need slower, broader medication review

NICE advises particular attention to drug interactions and comorbidities in older people starting antiseizure medication, usually using lower starting doses and slower titration where appropriate.

Kidney and liver function, frailty, falls, sedation and the total medicine burden may all influence treatment choices.

Falls and fractures can become a larger part of risk

The consequences of a seizure-related fall can become more serious when osteoporosis, frailty, anticoagulant use or impaired balance is present.

This is why later-life safety planning should consider both seizure control and the person’s wider health.

Epilepsy and dementia can overlap

Epilepsy and dementia have a bidirectional association. A 2024 systematic review and meta-analysis found increased seizure/epilepsy risk in people with dementia and also examined dementia risk among people with epilepsy.

New episodes of confusion or altered awareness in an older person therefore need careful assessment: they may reflect seizures, postictal states, delirium, medication effects, stroke or neurodegenerative disease.

Longstanding epilepsy does not explain every new symptom

As people age, new medical conditions become more likely. New weakness, speech problems, fainting, confusion, memory decline, falls or behavioural changes should not automatically be labelled as “the epilepsy”.

Stroke, cardiac disease, infection, metabolic disturbance and medication toxicity are among the alternative explanations clinicians may need to consider.

Some people need more frequent review

NICE recommends at least annual monitoring for adults with factors such as learning disability, drug-resistant epilepsy, high SUDEP risk, serious comorbidity, complex cognitive or mental-health problems, or antiseizure medicines associated with long-term side effects or interactions.

People with ongoing seizures should also have access to epilepsy specialist nursing support, with NICE recommending specialist nurse sessions at least twice yearly and after A&E visits.

Independence is not a straight line

Support needs can increase or decrease across life. A young adult may become more independent; later, worsening seizures, cognitive change, frailty or another illness may increase the need for help again.

Care planning should therefore be reviewed when circumstances change rather than assuming that one level of support will remain appropriate indefinitely.

Quality of life is a lifespan outcome

Seizure frequency matters, but it is not the only outcome. Education, relationships, work, cognition, mental health, independence, sleep, side effects and social participation all contribute to quality of life.

A person whose seizures are “better” may still need substantial support if medication adverse effects, memory problems or fear of seizures remain disabling.

The central point

Epilepsy care should evolve with the person. The relevant questions at age 8, 18, 38 and 78 are not identical, even when the diagnosis is.

Regular review should ask not only “How many seizures?” but also “What has changed in this person’s life, health, treatment, risks and priorities?”
