Can You Feel a Seizure Coming On? A Comprehensive Guide

Yes, for many individuals with epilepsy, it is possible to feel a seizure coming on. This experience can manifest in various ways, ranging from subtle premonitions to distinct physical or emotional changes. These warning signs can be broadly categorized into prodromes and auras, offering valuable time for preparation and potential intervention. Understanding these signals is crucial for managing epilepsy and improving the quality of life for those affected.

Understanding the Premonitory Signals

It’s important to differentiate between prodromes and auras, as they represent different phases and intensities of pre-seizure symptoms.

Prodrome: The Distant Early Warning

The prodrome refers to changes in mood, behavior, or physical state that can occur hours or even days before a seizure. These signs are often nonspecific and can be easily overlooked or attributed to other causes. Common prodromal symptoms include:

• Changes in Mood: This could involve increased irritability, anxiety, depression, or a general sense of unease.
• Headache: Some individuals experience a persistent or intensifying headache in the days leading up to a seizure.
• Sleep Disturbances: Both insomnia and excessive sleepiness can be prodromal symptoms.
• Cognitive Changes: Difficulty concentrating, memory problems, or a feeling of mental fogginess may also occur.

Aura: The Immediate Precursor

The aura, on the other hand, is considered the initial part of the seizure itself. It’s a focal seizure that provides a more direct and immediate warning. Auras are more distinct and often consistent for each individual, making them a reliable indicator of an impending seizure. Aura sensations can vary widely and may include:

• Sensory Changes: These are some of the most common auras, including visual disturbances (flashing lights, blurred vision), auditory hallucinations (ringing in the ears, distorted sounds), olfactory hallucinations (strange smells), or gustatory hallucinations (unusual tastes).
• Emotional Changes: Intense feelings of fear, anxiety, déjà vu, or jamais vu (the opposite of déjà vu, a feeling of unfamiliarity with a familiar place or situation) can occur.
• Physical Sensations: These may include a rising sensation in the stomach, tingling or numbness in a limb, dizziness, or a feeling of detachment from the body.
• Cognitive Changes: Difficulty speaking, understanding speech, or experiencing distorted perceptions of time or space.

Recognizing Your Personal Warning Signs

The key to effectively managing epilepsy and utilizing these pre-seizure signals lies in meticulous self-observation and communication with your healthcare team. Keeping a detailed seizure diary can be invaluable in identifying patterns and triggers. Record the following:

• Date and Time: When did the prodrome or aura occur?
• Specific Symptoms: Describe the sensations, emotions, or changes you experienced in detail.
• Duration: How long did the prodrome or aura last?
• Triggers: Were there any potential triggers present, such as stress, sleep deprivation, or missed medication?
• Seizure Outcome: Did a seizure follow the prodrome or aura? If so, what type of seizure was it?

By consistently tracking this information, you can gain a deeper understanding of your individual seizure patterns and identify your personal warning signs. Share this information with your doctor to develop a personalized management plan.

What to Do When You Feel a Seizure Coming On

Recognizing an impending seizure allows you to take proactive steps to protect yourself and minimize potential harm. Depending on the severity and predictability of your seizures, these steps may include:

• Moving to a Safe Location: If you’re in a potentially dangerous environment (e.g., driving, swimming, using machinery), immediately move to a safe place.
• Alerting Others: Inform someone nearby that you’re about to have a seizure so they can provide assistance if needed.
• Taking Rescue Medication: If prescribed by your doctor, administer your rescue medication (e.g., nasal spray, rectal gel) as directed.
• Relaxation Techniques: If anxiety or stress is a trigger, practice relaxation techniques such as deep breathing, meditation, or visualization.
• Avoiding Triggers: If you know specific triggers that precede your seizures (e.g., strong smells, flashing lights), try to avoid them.
• Laying Down: If possible, lie down on your side to prevent injury and aspiration.

When to Seek Medical Attention

While recognizing pre-seizure signals can be empowering, it’s essential to seek medical attention in the following situations:

• New or Changing Auras: If you experience new or different auras, it could indicate a change in your seizure pattern or underlying condition.
• Prolonged Auras: Auras that last longer than usual may be a sign of status epilepticus, a medical emergency.
• Increasing Seizure Frequency: If you notice an increase in the frequency of your seizures, even with recognizable auras, consult your doctor.
• Uncertainty: If you’re unsure whether you’re experiencing an aura or another medical condition, err on the side of caution and seek professional evaluation.

Living Well with Epilepsy

Epilepsy management is a collaborative effort between you and your healthcare team.

Frequently Asked Questions (FAQs)

1. What is the difference between an aura and a hallucination?

An aura is part of a seizure, caused by abnormal electrical activity in the brain. A hallucination, on the other hand, is a sensory perception that occurs without an external stimulus and is typically associated with psychiatric or neurological conditions. Auras tend to be more consistent for each individual, while hallucinations can vary widely.

2. Can stress trigger an aura?

Yes, stress can be a significant trigger for seizures and, consequently, auras. Emotional and physical stress can disrupt the brain’s electrical balance, increasing the likelihood of a seizure.

3. Are auras always followed by a full-blown seizure?

No, not always. Sometimes, an aura can occur without progressing to a generalized seizure. These are often referred to as simple partial seizures or focal aware seizures. However, it’s crucial to treat every aura as a potential warning sign and take appropriate precautions.

4. Can children experience auras?

Yes, children can experience auras, but they may have difficulty describing them. Pay attention to changes in their behavior, such as staring, confusion, or unusual movements.

5. What if I don’t experience any auras?

Many people with epilepsy do not experience auras. This doesn’t mean their epilepsy is more severe, but it highlights the importance of other management strategies, such as medication adherence and trigger avoidance.

6. Can lack of sleep trigger a seizure?

Yes, lack of sleep is a well-known seizure trigger. Sleep deprivation can lower the seizure threshold, making it more likely for a seizure to occur.

7. What are “silent seizures”?

Silent seizures, also known as absence seizures, are characterized by a brief loss of awareness without convulsions. They may involve staring, eye blinking, or subtle movements.

8. Can I drive if I have auras?

Driving restrictions vary depending on the laws in your area and the frequency and predictability of your seizures. Consult your doctor and your local Department of Motor Vehicles for specific guidelines.

9. Can dehydration cause seizures?

Yes, dehydration can increase the risk of seizures. Maintaining adequate hydration is essential for overall health and seizure management.

10. Is there a way to stop a seizure once the aura starts?

While there’s no guaranteed way to stop a seizure after the aura begins, some individuals find that certain techniques, such as taking rescue medication or practicing relaxation techniques, can help prevent the seizure from progressing. In the case of a Jacksonian seizure, firmly squeezing the muscles around those that are twitching can sometimes halt the attack.

11. What can be mistaken for an aura?

Various conditions can mimic auras, including migraine headaches, panic attacks, transient ischemic attacks (TIAs), and psychiatric disorders. It’s essential to consult a neurologist for accurate diagnosis and management.

12. Are there any dietary changes that can help prevent seizures?

While there’s no one-size-fits-all diet for epilepsy, some individuals find that following a ketogenic diet (high-fat, low-carbohydrate) can help reduce seizure frequency. However, it’s crucial to consult a registered dietitian or nutritionist before making significant dietary changes.

13. Can flashing lights trigger seizures?

Yes, flashing lights can trigger seizures in individuals with photosensitive epilepsy. Avoid exposure to strobe lights, video games with rapid flashing patterns, and certain television programs.

14. What vitamins are important for people with epilepsy?

While a balanced diet is generally recommended, certain vitamin deficiencies can increase the risk of seizures. In some rare cases, Pyridoxine (vitamin B6) deficiency is a recognised cause of intractable seizures. Talk to your doctor about whether vitamin supplementation is necessary.

15. Where can I find support groups for people with epilepsy?

Many organizations offer support groups for people with epilepsy and their families. Some of these groups may be found at GamesLearningSociety.org or through the Epilepsy Foundation, the Epilepsy Research Fund, or local hospitals and clinics. These groups can provide valuable emotional support, information, and resources.
