The Purpose of Keppra and the Reality of Breakthroughs
Keppra, the brand name for levetiracetam, is an anticonvulsant medication used to treat various types of seizures in people with epilepsy. It is often prescribed as a standalone treatment or, more commonly, as an adjunct therapy alongside other antiepileptic drugs (AEDs) to help control seizure activity. While effective, Keppra, like any medication, cannot guarantee complete seizure freedom for every individual. Breakthrough seizures, which are seizures that occur despite taking medication as prescribed, can happen for a multitude of reasons.
Common Reasons for Breakthrough Seizures on Keppra
Understanding the potential causes behind breakthrough seizures is the first step toward better management. These reasons can be broadly categorized into medication-related issues and external or lifestyle factors.
Medication-related causes
- Missed or Inconsistent Doses: This is one of the most common causes of breakthrough seizures. Anti-epileptic medications like Keppra rely on maintaining a consistent level in the bloodstream to be effective. Skipping a dose or taking it irregularly can cause this level to drop, making a seizure more likely.
- Incorrect Dosage: The dose of Keppra may simply be too low to effectively control seizure activity for a specific individual, especially if it has been months since the last adjustment. Dosage requirements can change over time, and regular check-ups with a neurologist are crucial.
- Drug-Resistant Epilepsy: For about one-third of people with epilepsy, seizures cannot be fully controlled by medication alone. In these cases, consistent breakthrough seizures may indicate the epilepsy is resistant to the current medication regimen.
- Unexpected Drug Interactions: While Keppra is known for having minimal drug-drug interactions compared to other AEDs, taking certain other medications or substances (like large amounts of caffeine) can still affect its effectiveness.
Lifestyle and External Triggers
- Sleep Deprivation: Lack of sleep is a well-known seizure trigger. Even when on medication, an inadequate or inconsistent sleep schedule can disrupt brain activity and increase the risk of a seizure.
- Increased Stress: High levels of emotional or physical stress can lower a person's seizure threshold. For some, this stress can be a direct trigger, overriding the protective effect of Keppra.
- Alcohol and Substance Use: Consuming alcohol or other recreational drugs can interfere with Keppra's efficacy and increase seizure risk.
- Illness or Infection: A fever or other systemic illness can alter the body's chemistry and metabolism, potentially triggering seizures. This can also happen in patients with underlying autoimmune dysfunction and inflammation.
- Hormonal Changes: For women, hormonal fluctuations during the menstrual cycle, pregnancy, or menopause can influence seizure frequency and make breakthrough seizures more common.
What to Do After a Breakthrough Seizure
Experiencing a breakthrough seizure while on Keppra is a serious event that warrants a prompt and structured response. It is vital to consult your physician after any seizure to evaluate the cause and adjust your treatment plan.
- Seek Medical Consultation: After ensuring immediate safety during the seizure, contact your neurologist as soon as possible. Do not change your dosage or stop taking Keppra suddenly, as this can cause even more frequent and severe seizures.
- Start a Seizure Diary: Keep a detailed record of each seizure, including the date, time, duration, and any possible triggers. A diary can help identify patterns related to missed doses, sleep schedules, or stress levels. Numerous mobile apps, such as Epsy Health, can help with this.
- Review Medication Adherence: Honestly assess your medication schedule. If missed doses are a factor, discuss strategies with your doctor to improve consistency, such as using pillboxes or reminder apps.
- Evaluate Lifestyle Factors: Address potential triggers by prioritizing adequate sleep, managing stress through techniques like mindfulness or counseling, and reducing or eliminating alcohol consumption.
- Re-evaluate the Treatment Plan: Based on your seizure diary and discussion, your doctor may recommend adjusting your Keppra dosage. If dose optimization is not effective, they might consider adding a second antiepileptic medication or exploring alternative treatment options for drug-resistant epilepsy.
Management Strategies: Medications vs. Lifestyle Factors
Managing epilepsy effectively often requires a dual approach that addresses both pharmacology and lifestyle. The following table compares how these two aspects influence seizure control and what interventions are typically used.
| Aspect | Medication-Related Management | Lifestyle-Related Management |
|---|---|---|
| Primary Cause | Suboptimal drug level, drug-resistance, or interaction | Stress, sleep deprivation, alcohol, or illness |
| Assessment | Physician consultation, serum level monitoring, and efficacy review | Patient self-assessment, seizure diary, and trigger analysis |
| Key Interventions | Adjusting Keppra dosage or adding a different AED | Improving sleep hygiene, managing stress, and avoiding triggers |
| Effectiveness | Depends on severity of epilepsy and drug-resistance | Can significantly reduce frequency, but may not eliminate all seizures |
| Treatment Focus | Altering brain chemistry to increase seizure threshold | Modifying external and internal factors that lower seizure threshold |
Alternative Therapies for Drug-Resistant Epilepsy
If pharmacological interventions with Keppra and other AEDs prove insufficient, specialists may recommend alternative therapies for drug-resistant epilepsy. These options are typically explored in comprehensive epilepsy centers.
- Epilepsy Surgery: In some cases, seizures originate from a specific, resectable area of the brain. Surgery to remove this area can lead to seizure freedom or significant improvement.
- Neurostimulation Devices: The vagus nerve stimulator (VNS) or responsive neurostimulation (RNS) systems are surgically implanted devices that send electrical pulses to the brain to help regulate abnormal electrical activity.
- Ketogenic Diet: This high-fat, low-carbohydrate diet can be an effective treatment for some types of epilepsy, particularly in children. It must be managed under strict medical supervision.
- Autoimmune Therapy: If an underlying autoimmune dysfunction is suspected, specific treatments may be used to address the inflammatory and neurological issues.
Conclusion
While Keppra is a cornerstone of epilepsy treatment, the possibility of experiencing breakthrough seizures remains a reality for many patients. Effective management requires a proactive and collaborative approach between the patient and their healthcare provider. By meticulously tracking seizures, identifying and mitigating lifestyle triggers, and consistently adhering to the prescribed regimen, patients can improve their chances of achieving better seizure control. When seizures persist despite optimized medication and lifestyle management, exploring advanced treatment options with an epilepsy specialist is a crucial next step toward improving quality of life.
