Are there long term risks to my health from epilepsy?
Living with epilepsy is a journey that often requires looking beyond immediate seizure control to consider long term health and wellbeing. While most people with epilepsy live full and healthy lives, the condition can have cumulative effects on the body and brain over many years. Clinically, these risks are not guaranteed but are potential complications that medical teams monitor during annual reviews. Many of the long term risks associated with epilepsy are related to the frequency of seizures, the underlying cause of the condition, and the physiological impact of long term medication use.
The goal of modern epilepsy management is to mitigate these risks through early and effective intervention. By understanding how the condition can affect areas like bone density, memory, and heart health, you and your medical team can take proactive steps to protect your future health. Knowledge of these risks is not meant to cause alarm but to empower you with the information needed to make informed choices about your treatment and lifestyle.

- Emergency guidance for identifying signs of health deterioration
Cognitive function and memory over time
One of the most common concerns for individuals with long term epilepsy is how the condition might affect their thinking and memory skills.
Memory and processing speed
Recurrent seizures, particularly those that are frequent or involve the temporal lobe, can place a strain on the brain electrical networks. Over many years, this may lead to subtle changes in memory, word finding, and the speed at which you process information. In some cases of uncontrolled epilepsy, the brain memory centers, such as the hippocampus, can undergo structural changes. However, it is important to note that achieving good seizure control is the most effective way to protect your cognitive health for the long term.
Bone health and anti seizure medication
Long term use of certain anti seizure medications can have a significant impact on your bone mineral density.
Risk of osteoporosis and fractures
Some older generations of epilepsy drugs are known to interfere with how the body processes vitamin D and calcium. This can lead to a gradual weakening of the bones, known as osteopenia or osteoporosis, which increases the risk of fractures. Clinicians often recommend regular bone density scans, also known as DEXA scans, for patients who have been on these medications for many years. Supplementing with vitamin D and maintaining a diet rich in calcium are standard clinical strategies to mitigate this specific long term risk.
Mental health and emotional wellbeing
Epilepsy and mental health are closely linked, with research suggesting a bidirectional relationship between the two.
Depression and anxiety
Individuals with epilepsy have a higher statistical risk of developing mood disorders such as depression and anxiety compared to the general population. This can be due to the biological impact of seizures on the brain emotional centers, the side effects of certain medications, or the psychological stress of living with an unpredictable condition. Proactive mental health support and regular screening during epilepsy reviews are vital components of long term care to ensure that emotional wellbeing is prioritized alongside physical safety.
Cardiovascular and general health
Clinical research has highlighted the importance of monitoring heart health in people with chronic epilepsy.
The heart brain connection
Repeated seizures can place intense physical demands on the cardiovascular system. Over a lifetime, this can potentially lead to changes in heart rhythm or structure, a concept sometimes referred to as the epileptic heart. Additionally, people with epilepsy may have a slightly higher risk of other conditions such as high blood pressure or stroke. Maintaining a heart healthy lifestyle, including regular exercise and a balanced diet, is an essential part of a comprehensive long term health strategy.
Comparison of potential long term risks
| Health Area | Potential Long Term Risk | Primary Prevention Strategy |
| Cognition | Memory loss or mental slowing | Optimize seizure control early |
| Skeletal | Osteoporosis and fractures | Vitamin D and DEXA screenings |
| Psychological | Chronic depression or anxiety | Regular mental health screening |
| Cardiac | Changes in heart rhythm | Regular blood pressure and EKG checks |
| Physical | Cumulative injury from falls | Safety modifications and monitoring |
| Social | Isolation or unemployment | Vocational support and counseling |
Reducing long term risks through proactive care
The best way to manage long term risks is through consistent, high quality clinical care and healthy lifestyle choices. Attending your annual epilepsy review is the most important step in protecting your future health. These reviews allow your specialist to check for silent side effects of medication, monitor your mental health, and ensure your treatment plan is still the most effective option. Staying physically active, avoiding tobacco, and limiting alcohol also play a significant role in reducing the overall burden of the condition on your body over time.
Emergency guidance
Knowing when to seek urgent help is vital for preventing long term neurological damage. Call 999 immediately if a seizure lasts more than five minutes or if a person has a cluster of seizures without regaining consciousness. This state, known as status epilepticus, is a medical emergency that can have serious long term health consequences if not treated rapidly. If you notice a sudden and significant decline in your memory or a dramatic shift in your mental health, seek a priority clinical review with your specialist to ensure your treatment plan is safe and effective.
Will I definitely develop memory problems?
No. Many people with well controlled epilepsy have normal memory and cognitive function throughout their lives. The risk is highest for those with frequent, uncontrolled focal seizures.
Does everyone on epilepsy medication need bone scans?
Not everyone, but it is often recommended for those who have been taking enzyme inducing medications for more than two years or for individuals with other risk factors for bone loss.
Can long term epilepsy be cured?
While some people outgrow epilepsy or achieve permanent remission through surgery or medication, for others it is a managed long term condition similar to diabetes or asthma.
Is SUDEP a long term risk?
SUDEP is a rare but serious risk. The best way to reduce this risk over the long term is to achieve the best possible control of generalized tonic clonic seizures.
Should I take vitamin D supplements?
Many specialists recommend vitamin D for patients on long term anti seizure medication, but you should discuss the appropriate dosage with your doctor based on your blood test results.
Does epilepsy cause dementia?
While chronic uncontrolled epilepsy can lead to cognitive decline, it is not the same as Alzheimers disease. Effective seizure management is the primary way to protect long term brain health.
