Demystifying Epilepsy and Seizures: Types, Triggers, and Care

Epilepsy is one of the most common neurological conditions worldwide, yet it remains widely misunderstood. This lack of awareness often leads to stigma, social isolation, and incorrect first aid responses. Demystifying epilepsy—understanding what causes seizures, how they are treated, and what to do when someone has one—is crucial for supporting those living with the condition.

What is a Seizure?

A seizure is a sudden, uncontrolled electrical disturbance in the brain. It can cause temporary changes in behavior, movements, feelings, and levels of consciousness.

Having a single seizure does not mean you have epilepsy. Epilepsy is generally diagnosed when a person has had two or more unprovoked seizures, spaced at least 24 hours apart, that are not caused by an immediate medical issue (like low blood sugar or high fever).

Types of Seizures

Seizures can look very different depending on where they start in the brain and how far they spread. They are broadly divided into two main categories:

1. Focal Seizures

Focal (or partial) seizures start in a specific area of the brain:

Focal Aware Seizures: The person remains fully conscious but may experience sensory changes (like a strange taste or smell), sudden emotional shifts, or involuntary jerking of a limb.
Focal Impaired Awareness Seizures: The person experiences a change in consciousness or awareness. They may stare blankly, repeat certain movements (like lip-smacking or hand-rubbing), or seem confused and unresponsive.

2. Generalized Seizures

Generalized seizures involve both sides of the brain from the onset:

Tonic-Clonic Seizures (formerly Grand Mal): The most dramatic type. The person loses consciousness, their body stiffens (tonic phase), and their muscles rhythmically jerk (clonic phase).
Absence Seizures (formerly Petit Mal): More common in children. The person briefly stares blankly into space for a few seconds, with no memory of the event, and immediately returns to normal.
Myoclonic and Atonic Seizures: Involve sudden, brief muscle jerks (myoclonic) or a sudden loss of muscle tone causing the person to fall (atonic or “drop attacks”).

Common Seizure Triggers

While seizures can occur unexpectedly, many individuals with epilepsy find that certain factors increase their risk:

Missed Medication: The most common trigger for breakthrough seizures.
Lack of Sleep: Fatigue significantly lowers the brain’s seizure threshold.
Stress & Anxiety: Extreme emotional stress can act as a major trigger.
Alcohol or Substance Use: Both drinking and the subsequent withdrawal phase can trigger seizures.
Illness or Fever: Infections can strain the neurological system.
Photosensitivity: Flashing lights or specific visual patterns (affects a small percentage of patients).

Seizure First Aid: What to Do

If you witness someone having a tonic-clonic seizure, remaining calm and following these basic steps can save them from injury:

Keep Them Safe: Gently help them to the floor. Move sharp or hard objects out of the way. Place something soft (like a folded jacket) under their head.
Turn Them on Their Side: Once the shaking stops, or if they are salivating/vomiting, gently roll them onto their side (the recovery position) to keep their airway clear.
Time the Seizure: Note when it started and how long it lasted.
DO NOT Restrain Them: Do not try to hold them down or stop their movements.
DO NOT Put Anything in Their Mouth: Contrary to popular myth, people cannot swallow their tongues, and putting objects in their mouth can cause choking or dental damage.

When to Call an Ambulance: Call emergency services if the seizure lasts longer than 5 minutes, if another seizure starts immediately after the first, if the person is injured, or if they do not regain consciousness.

Modern Treatment Options

Most people with epilepsy can live full, active lives with appropriate treatment:

Anti-Seizure Medications (ASMs): The primary treatment method, which effectively controls seizures in about 70% of patients.
Dietary Therapies: Specific diets, such as the ketogenic diet, are sometimes used alongside medication, particularly in children.
Neuromodulation and Surgery: For drug-resistant epilepsy, advanced procedures like Vagus Nerve Stimulation (VNS) or surgical resection of the seizure focus can offer significant relief.

Consulting an experienced neurologist is key to achieving seizure control and finding the right medication regimen. For expert guidance on diagnosis, EEG evaluation, and long-term care, consult Dr. Annapureddy Jagadish at Medicover Out Patient Center, Hitech City, Hyderabad.
